Nie Yan took out another third-tier fire-系 crystal core. The Darkwing Dragon glanced at the fire-系 crystal core and turned its head away. It didn't seem to care much for fire-系 crystal cores, but it would definitely eat it. It was estimated that the effect wouldn't be very good.
It seemed that to feed a certain type of flying mount, you had to use crystal cores of the same type. For example, to feed the Darkwing Dragon, you had to use dark-系 crystal cores so as not to waste them.
Nie Yan tossed a dark-系 crystal core into the air.
The Darkwing Dragon quickly turned its head and snapped it up in its mouth with lightning speed, then crunched it and swallowed it.
Nie Yan could feel that the Darkwing Dragon was a little stronger than before, but it was just a vague feeling. He didn't know how long it would take for the Darkwing Dragon to advance.
After eating a crystal core, the Darkwing Dragon looked at Nie Yan expectantly, as if it wanted more.
Nie Yan took out another dark-系 crystal core and tossed it to the Darkwing Dragon.
The Darkwing Dragon chomped down on the crystal cores. Since the Darkwing Dragon was a sixth-tier creature, these first, second, and third-tier crystal cores had very limited effects on it, but if the quantity reached a certain level, the effect would be completely different. Nie Yan could feel the powerful dark energy emanating from the Darkwing Dragon, full of corrosive power. Plants within a three-yard radius of this dark energy immediately withered into dry grass.
The Darkwing Dragon burped, its belly bulging. It had eaten at least a dozen crystal cores since earlier.
After eating these crystal cores, the Darkwing Dragon dozed off. Nie Yan saw that it was about to fall asleep, so he took it back into his pet space.
Looking at the pet space, the Darkwing Dragon had already found a place to sleep, and a rich dark aura enveloped it, completely surrounding it.
The Darkwing Dragon fell into a deep sleep.
Nie Yan could feel the powerful force surging within it. He wondered what kind of changes would occur after it woke up.
Nie Yan withdrew his gaze. He continued to level up his various production skills while doing the Holy Shadow Dancer class-change quest. Gradually, he reached the depths of the jungle. Looking into the distance, a magical and bizarre building, suspended in the air above the jungle, attracted his attention.
This building was very magnificent, completely floating, without any support, like a huge fortress. It had experienced countless wars and was scarred, but it was still very grand and spectacular.
Like Carol City in Greenland, it was a Sky City.
System: You have discovered the World Heart.
Nie Yan was stunned when he saw this system prompt, and his heart trembled. It was actually the World Heart!
In the myths of the Curtis Codex, the World Heart was the center of the world, suspended above the Atlanta Continent, and was where the gods lived. However, after the Third War of the Gods, the World Heart disappeared without a trace and never appeared again.
Therefore, the World Heart was only described in a few words in some ancient books, and everyone regarded the World Heart as an ethereal existence.
Nie Yan intuitively felt that this World Heart must be related to the Holy Shadow Dancer class-change quest, so he proceeded in the direction of the World Heart.
The closer he got to the World Heart, the stronger the monsters that spawned. Nie Yan's speed gradually slowed down. Looking up, he saw some black dots circling and dancing around the World Heart. They were some flying creatures. Although he had never encountered these flying creatures, judging from their size, the tiers of these flying creatures were very high, much stronger than his Darkwing Dragon.
After about ten days, Nie Yan completed Quest Progress 3, and another system prompt sounded.
Quest Progress: Infiltrate the World Heart and find the lost inheritance.
The quest had finally changed somewhat. He would go crazy if he continued to clear monsters. Third-tier creatures were already very difficult to deal with, let alone fourth and fifth-tier creatures! After completing the first three quest progresses, the subsequent quests were very different, but infiltrating the World Heart was much more difficult than the previous quest progresses.
Looking at the World Heart in the distance, he would definitely need to use a flying mount to enter the World Heart. He looked down at his pet space. The Darkwing Dragon was still asleep.
Forget it, he could only wait for the Darkwing Dragon to wake up. Nie Yan collected materials everywhere and continued to improve his various production skills. He looked at the levels of his various production skills. Machinist, Forging, and Scroll skills had all reached Advanced and were ready to advance to Master. In addition, his Alchemy Master skill had reached 52% of Master level, and he could make more potions.
As he learned more and more production skills, Nie Yan had some new understandings of production skills. He suddenly had some magical ideas. Could he make his own weapons?
Nie Yan obtained some iron essence, forged and processed it, and then slowly ground it into a needle shape, about three inches long and about the thickness of a thumb. One end was ground very sharp, which could easily pierce protection. Then, using his Alchemy Master skill, he made bottles of blue poison and evenly smeared the poison on the needles.
This could be considered a handy weapon, which could be used in some unexpected situations. Nie Yan thought for a while. This thing could be strengthened even further. He used his Machinist skill to give the iron needle a special treatment. Once this iron needle pierced into the enemy's body, it would form barbs, hooking the flesh. It was impossible to pull it out. If it was forcibly pulled out, a large piece of flesh would be torn off.
This could be regarded as a bit of Nie Yan's ingenuity. At this moment, a system prompt sounded.
System: You have invented a weapon, Attack Rating (Strength * 5 + 5000), Special Effect Rating. This weapon can cause 20% bleeding effect for ten seconds, and has a certain probability of crippling the opponent. Please name it.
Nie Yan looked at the attributes of this weapon. He didn't expect it to have such an effect. This attack was extremely amazing, and it also came with bleeding and crippling effects. Nie Yan's strength was about 6,000 points. If he used it to attack an enemy, it could cause more than 30,000 points of damage, and at the same time, it could cause more than 60,000 points of bleeding damage. It was simply terrifying.
What should he name this thing?
Nie Yan pondered for a moment, then decided to call it Bone Spike.
System: Naming successful.
System: You have successfully invented and crafted a Bone Spike. Forging and Machinist skills each gain 500 skill proficiency.
Two beams of white light lit up on Nie Yan's body. It was the sound of advancement! Nie Yan opened the skill list, and Forging and Machinist had both advanced to Master level. He didn't expect to gain so much skill proficiency all at once!
The skill proficiency increased so quickly! Nie Yan continued to make the second Bone Spike, but this time Forging and Machinist only gained 5 skill proficiency each. It seemed that only when inventing a weapon could he gain so much skill proficiency at once.
Even so, making Bone Spikes gave much more skill proficiency than making ordinary weapons, and it could improve both Forging and Machinist skills at the same time, which was obviously more cost-effective.
Only now did Nie Yan feel how useful it was to have learned all the production skills!
Ordinary players usually only have one production skill. Even if they improve it to a very high level, they can only produce various items according to blueprints and recipes. It is impossible for them to independently develop and produce a high-level item like Nie Yan, because generally high-level items require at least two or more technologies to assist them. Even just preparing and making new potions is not something that can be done casually. It also requires the assistance of other production professions, such as making special containers, etc.
The Bone Spike's power exceeded Nie Yan's expectations. In the future, it could be used as a powerful auxiliary weapon. In a few more days, all of his production skills would be at Master level. At that time, he could independently develop more things and use these special items to make himself even stronger.
Just as he was thinking, a violent fluctuation came from the pet space, and a powerful dark energy filled the entire pet space, overflowing from the pet space.
What happened? Nie Yan was shocked and looked into the pet space. He saw a powerful dark force being released from the Darkwing Dragon's body. It stood up, its body was a bit larger than before, and a layer of gray-black scales covered it, densely covering the Darkwing Dragon's entire body, like a layer of scale armor protecting the Darkwing Dragon, reflecting a black, crystal-clear luster.
The Darkwing Dragon's wings were more powerful than before, and its strong body gave people a feeling of unmatched power.
Nie Yan glanced at the Darkwing Dragon's attributes. All attributes had increased by at least 30%. The Darkwing Dragon was not far from advancing, only a little bit away. If he continued to feed the Darkwing Dragon crystal cores, it might advance to the seventh tier before long. If it could advance to the seventh tier, its strength would increase several times.
Currently, the highest-tier flying mounts owned by other players are only fourth tier. If there is a difference of three tiers or more, Nie Yan's Darkwing Dragon can easily crush all of their flying mounts.
The Darkwing Dragon had finally woken up. It could not continue to eat crystal cores in a short period of time. Nie Yan looked at the World Heart. He was going to ride the Darkwing Dragon up there!
Nie Yan prepared, made more than fifty Bone Spikes, and a large number of Master-level instant recovery potions. He also prepared some high-level bandages. After making sufficient preparations, he summoned the Darkwing Dragon.
The Darkwing Dragon appeared in the open space in front of him, and a powerful aura swept out. All the plants within a ten-yard radius were instantly drained of their vitality and withered in a moment.
Nie Yan looked up and found that the Darkwing Dragon's height had reached five yards, and its metallic scales were simply indestructible, giving people a sense of heavy oppression.
Nie Yan straddled the Darkwing Dragon's back. The Darkwing Dragon flapped its wings and soared into the air, rising tens of yards at once.
