Sullen moved the books on the bookshelf into his storage space like an ant moving house.

Sereia's erudition made the words in these books very clear.

The two also cherished this rare master-disciple time.

Sereia taught wholeheartedly.

Sullen also asked any questions that came to mind.

Looking at the spider lances on Sereia's body, he asked, "Teacher, what level of fusion is your spider lance implant?"

It was like the Eight-Armed Spider Lance, his own and Sereia's were vastly different.

Sereia smiled and said, "First level."

She naturally understood what Sullen was thinking, and added, "When I fused the spider lance implant, the design blueprint was much simpler than your current golden blueprint."

"Teacher, then your..."

Sullen became even more puzzled as he listened.

They were both first-level implants, so why was the difference so great?

"You want to ask why my spider lance looks so powerful?"

Sereia watched Sullen nod, and then explained with a smile, "The original purpose of Master Nicholas Flamel of the Ancient Era creating alchemical implants was to give alchemists a certain amount of combat power and to compensate for certain inadequacies of the human body by transplanting some alien biological limbs. But in fact, the significance of alchemical implants is not limited to this, it also represents the warlock's understanding of biological alchemy. The implant can be said to be the alien creature that a warlock knows best. Many people only know how to use it, but don't understand it, which is actually a misunderstanding. Do you know why the ultimate subject of alchemy, 'creating life,' is so difficult? Biological bodies are the most complex existence known so far, this is an understanding of the level of life, and implants are also a shortcut for us to understand biological bodies..."

Sereia explained in great detail, and Sullen understood.

He originally thought that the implant was just a piece of equipment with level restrictions. Like the spider lance on his body, it would be very useful in the first and second levels, but would become "outdated" in the third and fourth levels.

But in reality, it was not like that.

The implants on everyone's body were "growth-type equipment" that would become stronger and more perfect as the warlock understood the biological limbs and fused with curse characteristics.

The premise was that you had to learn knowledge and understand everything about this biological limb.

Theoretically speaking, as long as you understood it thoroughly, you could use the principle of equivalent exchange to possess everything.

This was the magical alchemy.

Just like his "spatial ability," he only knew how to use some superficial things now, and couldn't talk about understanding the laws of space at all.

When he could truly understand it, this ability would gradually become stronger.

This was also the difference between true experts in Sereia's words.

.......

Refining the [Isaac Alchemy Heart] would take about a whole day.

The master and disciple chatted in the alchemy laboratory for a whole day.

Sullen also noticed that as time passed, the scenery in the room began to become a little distorted. Like a cassette tape, the light and shadows were distorted.

He knew that this was a sign that the space was about to collapse.

The atmosphere suddenly became a little sad.

Sullen had a deep respect for this teacher he had only known for a day.

It was a respect from the levels of knowledge, cognition, and spirit.

This was a master-disciple relationship that had been missed for a thousand years.

Sereia, however, seemed calm. She could accept the fact that she was already dead and was also used to this kind of separation.

She wore a warm smile on her face and said to Sullen, "Speaking of which, you are my only formal disciple."

Hearing this, Sullen respectfully bowed.

It was time to say goodbye.

Sereia suddenly thought of something, took off a ring from her hand, and quickly wrote a string of characters on the ring with her finger as a pen. Then she handed it to Sullen and said, "Let the teacher give you a small gift."

[Sereia's Blessing]

Concentration +21

Comprehension +2

Luck +1

Description: A ring full of blessings, engraved with the words "Given to my disciple Sullen";

Detailed explanation: A seventh-level alchemical product, with the [Concentration] effect, it can make the wearer more focused and efficient when learning, casting spells, and working;

Although it was not a cursed object, it was fortunate that it was of a high level.

It was like a first-level gold equipment and an eighth-level white board equipment, the panel attributes were vastly different.

They were all very practical attributes, which would be of great help to his future learning.

Sullen looked at the golden ring, his eyes slightly complicated, and put the ring on his right index finger, "Thank you, teacher."

"You don't have to be so polite. After all, you are my disciple. Oh, right..."

Sereia looked at Sullen, probably thinking of her daughter, and also took off another ring and refined it in the same way.

She handed it to Sullen and said, "Give this to Pestoya when you see her in the future. As a mother, I really owe her..."

Sullen nodded solemnly: "Yes."

At this moment, the ground trembled slightly, and the space began to collapse.

The nine-mang star alchemy formation suddenly appeared again under Sereia's feet. She looked at it, pinched out the warlock seal with both hands, and shouted softly, "Release!"

At this moment, a red light flashed, and two things floated on the alchemy formation.

One was a hexagonal ancient lamp, naturally the [Vulcan's Furnace Lamp].

And the other was a heart wrapped in layers of runes.

Unlike the previously throbbing and lively heart, the refined heart had lost its activity and completely turned into a metallic luster, like a mechanical heart.

However, there were many seemingly exquisite and mysterious alchemical components on this alchemical heart, which made people see its extraordinaryness at a glance.

[Isaac's Alchemy Heart]

Quality: Epic

Detailed explanation: An alchemical implant made from the heart of a god-level creature; this is a great creation enough to be recorded in history; provides a continuous supply of dark spirit energy; minimum fifth-level containment value S+ rating, dark spirit energy value greater than 3 million, fusion malformation probability less than 10%; non-Fallen Angel bloodline professionals, 100% malformation after fusion; dark spirit energy recovery efficiency greatly improved after fusion, overall body toughness greatly improved, Fallen Angel bloodline purity greatly improved...

(Don't worry about why 'Epic' is higher than 'Legendary', this is how the book is set)

When Sullen saw the detailed explanation of this thing, he knew that this thing was by no means ordinary.

The two sealed objects in his hand were still "Legendary", but this heart was "Epic".

Moreover, the level was secondary.

The most important thing was that after fusing this thing, Sullen would have the legendary "infinite mana bar"!

The heart of a god had special law abilities, forming its own domain. It could naturally breathe in one world, converting all energy into dark energy.

Moreover, it could also improve the bloodline purity of the "X serum" and greatly increase the body's attributes.

Sereia held the heart in her hand and said, "This heart implant requires a very high curse tolerance value, at least you must be at the fifth level before you can possibly fuse it. In the later stages, the more puppets a puppeteer controls, the more dark spirit energy will be needed. This implant has a very high compatibility with you. As for the others, you have the [Omniscient Eye], so I don't need to say more..."

"Yes."

Sullen frowned as he listened.

The thing was good, but the fusion conditions were too exaggerated.

His current dark spirit energy value was less than 30,000, and fusion would require an increase of almost a hundred times. This was still the case after his bloodline transformation, ordinary people...100% malformation.

Time was tight, Sereia didn't talk nonsense. She pinched out the warlock seal with one hand and suddenly slapped the heart towards Sullen's chest with the other hand, shouting softly, "Godslaying Seal · Seal!"

Before Sullen could react, he suddenly felt as if the skin on his chest was burned for a moment.

Looking down again, there was a hole burned in his shirt, and a nine-mang star mark appeared on the skin of his chest.

After doing all this, Sereia explained, "But the overflowing energy of this thing is too violent for your current level. Even if it is placed in the storage space, it will cause malformation. I sealed it in your body, and in the future, you will have a source that you can draw dark spirit energy from at any time to practice. Listen carefully to the method of unsealing..."

Sullen was amazed when he heard this.

The methods of Sereia, this top warlock, were indeed unbelievable.

He also tried it, and quickly mastered the essentials.

That [Isaac Alchemy Heart], this seal was like a "faucet".

Open it and dark spirit energy would gush out.

Draw as much as you want, and that's how much you get.

This solved a big problem in Sullen's practice.

He was also thinking before that only in this Dawn Ruins was the dark spirit energy abundant, and the absorption efficiency was at least dozens of times that of Old Lingdun.

If possible, he even planned to practice here until he couldn't be promoted any further.

However, there was another big problem.

That was that this underground world was just a "mine pit". To break through to a higher level, he always had to go to the surface.

He also wanted to see that wider world.

And in the future, after going to the surface, the "dark spirit energy" would be very thin, and the practice at that time would be a big problem.

Using curse crystals or energy conversion arrays was possible, but that kind of practice method was completely burning money.

Sullen didn't think he had the financial resources to support it.

Now, this [Isaac Alchemy Heart] perfectly solved this problem.

It had to be said that Sereia, as a teacher, was really thoughtful.

Sullen also suddenly thought of why Mr. Mirror and the others were robbing other god limbs.

In addition to limiting that Fallen Angel from obtaining the power of the main body, this was probably also the purpose.

.......

The space had already begun to collapse, and Sereia's body also began to disintegrate. She explained the last few words.

"There's not enough time. I won't say anything else. In the other notebooks, there are also several kinds of alchemical implants researched by Isaac. If you can find them in the future, it may give you a lot of resistance on your future path..."

"I don't know where the end of death is. Maybe it's the underworld in mythology, or maybe it's completely dissipated. But I vaguely feel that if one day you comprehend the 'law of death,' maybe we will have a chance to meet again...Become stronger, my disciple."

"But with the heart on your body, that Fallen Angel will be able to sense it as soon as you go out. He will definitely come to you. Be careful, no one knows what will happen..."

"..."

Sullen listened carefully, nodding from time to time.

Sereia's figure had already begun to disintegrate from her feet, "Okay, time's up..."

Sullen bowed and saluted, "Farewell, teacher."

Sereia showed a loving smile. Before completely disappearing, she said one last sentence, "Oh, right. If possible, please take care of Pestoya for the teacher in the future. She has been in the cursed space alone for a thousand years, her temper may be a little strange, please be more accommodating to her..."

"Yes, teacher."

Sullen responded. When he looked up again, Sereia's last smiling face disintegrated before his eyes.

.......

The surrounding scenery changed, and the bright alchemy studio turned into a dark and dilapidated ruin.

The ruins of the five-mang star central prison were right in front of him, Sullen's eyes were like mist.

He touched his heart, where the seal was still hot.

Everything seemed so real, but it disappeared before his eyes.

The master-disciple relationship that spanned a thousand years had just begun and then ended.

Sereia's words were still vivid in his ears, Sullen's thoughts drifted a little.

At this time, Kai, who was not far away, saw him and called out, "Sullen, are you okay?"

Besides Kai, the only ones who were still alive were Leina and the old butler Anthony.

"Yes, I'm fine."

Sullen naturally knew that these few could survive, so he was not surprised.

In that cursed space, it was easy for Sereia to kill anyone.

As for the nearly a thousand people from the Oliver and Clark families, they were all buried in the space.

Sereia's silk threads that covered the entire prison made it easy to take anything, and the spoils naturally fell into Sullen's pocket.

The elite groups of the two major families, equipment, implants, supplies, job transfer materials...

The value was immeasurable.

It was not in vain that he had entered and exited the prison eight times before to arrange the layout and calculate this assassination.

Of course, Sullen felt that the biggest gain was meeting his teacher Sereia.

Kai was used to it.

Sullen could always do some unexpected things.

Even in this seemingly inevitable dead end.

But being able to survive this time completely exceeded Leina and Anthony's expectations.

Before, whether it was the siege by several major families or the "T-level" cursed space, they were unsolvable dead ends for them.

Unexpectedly, the situation reversed.

The ones who survived were actually them!

And all of this was because of the seemingly elegant and easy-going man in front of him.

Leina looked at the greatly changed Sullen, slightly incredulous, and obediently called out, "Mr. Sullen."

Sullen smiled at her, formally greeting her as "Sullen", "Yes. Long time no see, Miss Leina."

"Thank you for saving me again."

Leina couldn't see through where she was. The reason why she was able to survive was entirely because of the man in front of her.

Sullen smiled noncommittally.

After surviving the disaster, the pressure that had been suffocating her before disappeared. The worry that had been lingering on Leina's pretty face also disappeared. She blinked, and finally couldn't help but ask curiously, "Mr. Sullen, you... how could you be Zoro?"

"Now is not the time to talk,"

Sullen shook his head gently, not explaining this question much.

His eyes stared at the depths of the ruins, and he said with a serious expression, "You must leave the ruins immediately. Before long, there may be major changes in the ruins... It's best to stay far away from the ruins."

"Yes."

Hearing this tone, Leina's expression also became solemn.

She had always had a sense of inexplicable trust in Sullen's words. Although there were thousands of questions in her heart, she didn't ask much and nodded.

Kai, who was on the side, asked when he heard this, "Sullen, what about you?"

Sullen: "I still have things to do, it will be very dangerous for you to be with me."

Kai had now seen Sullen's true strength, so he naturally knew that this "monster" didn't need him to worry at all. He only said, "Well, then be careful yourself."

Leina also said, "Mr. Sullen, please take care of yourself."

.......

Although the old butler Anthony had not spoken all the time, when he was about to leave, he looked back for a moment, his eyes full of complexity. He sighed in his heart, "What a monstrous person..."

Although he had heard of the famous SS wanted criminal Sullen, he had never seen him before.

He never expected that this person was actually in the team before.

The young man with blue skin who had pretended to be "Zoro" before had already made his eyes light up.

He never thought that this Sullen was even more exaggerated to an unbelievable degree.

Looking at the young man with a gentle smile on his face, others would definitely not believe that his combat power was so amazing.

Even Anthony, a real third-level, felt a chill down his back.

If he was an enemy...he would probably have been killed already.

The scene quickly flashed through Anthony's mind.

He had personally witnessed Sullen's puppet legion head-on against the elite groups of the two major families, killed the "Wind and Thunder Sword King" Nero, and survived the battle with that bespectacled man who looked like a top expert...

No, maybe he had already killed him.

Moreover, he always felt that the Sullen in front of him gave him an unfathomable feeling.

However, everything was not important anymore.

The enemy was wiped out,

They survived.

Anthony also completely breathed a sigh of relief.

This time, the conspiracy of several major families to encircle and kill the eldest son of the Reis family was completely in vain. Even the two major families of Oliver and Clark would be greatly injured this time.

And the fact that he and Miss Leina did not die was already the best ending.

The group of three quickly evacuated, their figures disappearing into the thick fog of the ruins in the blink of an eye.
