"Enemy attack! Help! Enemy attack!"
As soon as Yang Hong charged into the world behind the black portal, someone immediately shouted an alarm!
"Damn it! Void Cleaving Slash!"
He hadn't expected to be so unlucky as to encounter people behind a teleportation portal. According to Zi Yi's memories, this portal was supposed to be unguarded.
It could only be said that Yang Hong had his unlucky moments too. The moment he entered, a cultivator from the Demonic Sect happened to be attempting to plunder blood food from the outside world for their amusement.
That demonic cultivator was even more unfortunate. He only managed to cry out thrice before being split into four pieces by two silver sword energies, one horizontal and one vertical, without even a chance to resist.
However, three shouts were enough. A rapid clanging sound echoed throughout the entire secret realm,
Instantly, figures flew from afar.
"Who dares to trespass into my Heart Demon Sect?"
"A cultivator, don't kill him yet. I want to toy with him, to squeeze out all his negative emotions."
"Leave some for me too..."
Upon seeing Yang Hong, the arriving demonic cultivators did not attack to avenge their fellow disciple, but instead cheered and discussed how to torment Yang Hong.
"A bunch of idiots! Don't you even look at my cultivation level?"
"Divine Firmament Thunder Technique – Thunder Dragon Roll!"
After a brief complaint, Yang Hong first applied three tier-eight [Vajra Talismans] and one tier-nine [Golden Armor Talisman] to himself. Then, channeling his mana to its fullest, he unleashed the tier-nine thunder technique [Divine Firmament – Thunder Dragon Roll].
"Stop him! That's a tier-nine thunder technique!"
"Charge! All of you, charge! Kill him!"
"Demonic Illusions Dance – Bewilder All Beings – Yin Spirits Chaos..."
Seeing the terrifying thunder technique brewing, all the demonic cultivators panicked. Their earlier elation turned into utter horror!
Countless spells, almost simultaneously, struck Yang Hong.
However, he had three tier-eight and one tier-nine spells on him. These hastily cast spells were simply incapable of breaking through his defenses.
"Thunder Dragon – Roll!"
After a spellcasting duration of about fifteen minutes, a lifelike purple thunder dragon, a hundred zhang long, surged forth from behind Yang Hong, carrying supreme majesty and the power to dispel evil, charging towards the demonic cultivators attacking him.
"Run~"
"Oh my goodness~ I want to go home~"
"My lord, spare me~ Spare me!"
As soon as the purple thunder dragon appeared, the over a hundred demonic cultivators who had gathered around Yang Hong and were desperately attacking immediately turned to flee, or knelt and begged for mercy.
Not a single one dared to resist!
What this secret realm was originally called is unknown. After the Heart Demon Sect discovered it, they renamed it the Heart Demon Secret Realm.
The Heart Demon Sect had operated in this secret realm for 380 years and had achieved considerable scale.
However, during the war between immortals and demons, the scripture "Duren Jing" had an overwhelmingly restraining effect on the Heart Demon Sect, causing them heavy losses.
From Zi Yi's memories, it was known that the Heart Demon Sect currently had only two Grand Elders in the ninth-tier Mahayana realm, one sect master in the eighth-tier Tribulation Transcendence realm, and nine cultivators in the seventh-tier Integration realm.
As for demonic cultivators below the seventh tier, due to the shortcut of rapid advancement, there were over forty thousand of them.
With such combat power, Yang Hong was confident he could clear them all out alone, even though he was only ostensibly at the early stage of the eighth-tier Tribulation Transcendence realm.
The over one hundred demonic cultivators, the highest cultivation among them being only seventh tier, were reduced to ashes by the attack of the purple thunder dragon, despite their numbers!
Lightning was naturally the bane of demonic arts, let alone a purple thunder dragon with the attribute of dispelling evil.
All demonic cultivators who were grazed by it died, those hit directly were obliterated!
Without exception!
Yang Hong followed behind the purple thunder dragon, consuming pills as he flew slowly.
This medium-sized secret realm, spanning only twenty thousand li in area, covered an area of four hundred million li. Yet, under Yang Hong's divine sense, nothing could escape his notice!
Under his powerful divine sense, no Heart Demon Sect cultivator could escape. He killed every single one he found!
Having read Zi Yi's memories, Yang Hong could only describe the Heart Demon Sect with one word: "deserving of death."
The cultivation of the [Heart Demon Sect] was quite perverse; they tortured others and absorbed their fear, anger, sadness, resentment, and other negative emotions to cultivate.
Finally, after the tortured person died, their corpse would be cooked, and their soul captured for artifact refining.
If one were captured by a cultivator of the [Heart Demon Sect], the best outcome was to commit suicide as quickly as possible.
"Senior, is there some misunderstanding between us?"
"Once you're dead, there will be no misunderstanding."
"Senior, spare me, this humble one is willing to surrender."
"No need for trouble, surrender is also death!"
"Master, this servant is willing..."
"Willingness to die is good."
Yang Hong showed no mercy to the pleas for mercy along the way, killing them all, even if they were children.
As long as they were demonic cultivators, as long as they had cultivation, they had at least ten lives on their hands. Therefore, there were genuinely no children in this secret realm.
Only demonic cultivators!
As Yang Hong's slaughter continued, the demonic cultivators began to flee towards the exit of the secret realm.
Unfortunately, at the exit, he had set up a tier-seven entrapment formation. Without tier-seven formation mastery, even a ninth-tier cultivator could not break it open.
*Boom*
The last Heart Demon Sect cultivator was blown into fragments by the collision of the Thunder Dragon Roll.
"Ninth-tier demonic cultivator? Heh heh~ Being restrained, it's still just a matter of one move."
After sensing and confirming that no one remained in the secret realm, Yang Hong prepared to leave and return to Clear Wind Manor.
However, as he reached the entrance of the secret realm, he couldn't help but look back.
"It would be a waste not to utilize such a secret realm. It's perfect for an experiment I've been unable to conduct. This secret realm is just right."
The more Yang Hong thought about it, the more feasible it seemed. He immediately turned and rummaged through his scale space.
"Heh~ I knew I had stored these two types of seeds in my scale space."
Saying this, Yang Hong scattered a silver seed and a golden seed before him.
With his left hand [Moonlight Jade Flowing Paste] and his right hand [Sunrise Creation Technique], he unleashed two spells, one silver and one purple. The cold demonic energy that had been surrounding Yang Hong was instantly forced back.
Laws of Creation and Time emanated from Yang Hong, and the twenty seeds instantly sprouted and began to grow rapidly.
To the outside observer, in just fifteen minutes, ten three-foot-tall, beautiful silver-blue "little grasses" began to bloom.
Ten golden-leafed large trees grew at a visible rate.
[Silver Moon Grass] and [Sunrise Fruit Tree] were both tier-four spiritual plants. They usually had little use and low medicinal value, only possessing Yin and Yang attributes respectively.
In this secret realm filled with demonic energy, they were perfect for purifying the demonic energy.
In just half an hour, the Silver Moon Grass bloomed with dandelion-like flowers. When the wind blew, the seeds scattered.
The Sunrise Fruit Tree bore fruit a little slower, but within an hour, it bore fruit and the fruits dropped.
As the twenty spiritual plants matured, Yang Hong's mana had been consumed by one-third;
When the newly dropped seeds matured again, his mana had only decreased by another quarter,
Because the matured spiritual plants would feed back a portion of mana to Yang Hong!
At this point, Yang Hong stopped his spell and walked to a Sunrise Fruit Tree, placing his hand on the trunk and simultaneously communicating with the [System] to issue the decree for boosting.
His mana flowed away rapidly, and the Sunrise Fruit Tree visibly grew larger.
"Ding~ You have boosted the tier-four spiritual plant Sunrise Fruit Tree with 2000 days of cultivation, gaining tenfold cultivation return, and receiving 20 million days of cultivation."
"Ding~ The Sunrise Fruit Tree has accumulated enough energy and begun to evolve... Evolution successful."
A surge of powerful spiritual energy poured into Yang Hong's body from the heavens and earth of the entire secret realm. He quickly circulated the "Clear Wind Breath Exercise" to continuously compress and refine the breakthrough cultivation.
An hour later, his suppression finally failed, and he broke through from the second level of Tribulation Transcendence realm to the third level.
But this was not the main point. The main point was that the karma generated on him this time was very little, only equivalent to the karma generated from killing a Mahayana realm cultivator.
"Haha~ As expected, although the secret realm is attached to the great world of Taiyuan Continent, it is still a separate world. The karma generated from plundering its world origin is much, much smaller than that of a true world!"
"Continue, continue!"
Yang Hong then switched to a Silver Moon Grass, and the effect was the same.
The only regrettable thing was that after the [System] was re-refined, it could only be used for boosting nine times a day.
After exhausting the daily boosting limit, Yang Hong immediately activated the Laws of Creation and Time to accelerate the growth of the two spiritual plants,
And also to plunder the world origin of this secret realm. His cultivation began to steadily increase.
A month passed in external time, and the entire secret realm was completely occupied by [Silver Moon Grass] and [Sunrise Fruit Tree].
"I hope this secret realm is sturdy enough."
Yang Hong muttered.
The demonic energy in the entire secret realm had completely vanished, becoming nutrients for the two spiritual plants. Other spiritual plants and creatures within the secret realm were also transformed into spiritual energy by the two laws, nurturing the two spiritual plants.
However, cracks began to appear in the sky of the secret realm.
