Chapter 837: Chapter 837: Fourth Layer of Tongxuan Realm

The Three-legged Demon Bull was preparing its massive attack, and the demonic power fermenting within its four horns was incredibly wild, posing a slight threat to Su Chengyu. Refusing to be negligent, Su Chengyu levitated into the sky, pointing his longsword towards the heavens, with bolts of lightning flashing in his eyes as he chanted an incantation.

"Nature’s spiritual energy of heaven and earth, dragon and tiger clash, endless heavenly thunder, heed my command!"

Over Su Chengyu’s head, dark clouds tumbled as a thick bolt of lightning descended. His body bathed in the majesty of the thunder, he swung the Dragon Slayer Sword, merging the True Way of Controlling Thunder with Sword Qi, bringing down might from the heavens, the thunder force immense.

The Three-legged Demon Bull’s powerful attack was also ready, as its four horns released demonic power, converging into a beam of light that shot into the sky, colliding with Su Chengyu’s Sword Qi imbued with the True Way of Controlling Thunder.

The demonic power of the Three-legged Demon Bull was indeed formidable, but Su Chengyu’s Dragon Slayer Sword naturally restrained the Beasts. Furthermore, heavenly thunder, being the most righteous and violent force in the world capable of purging all evil spirits, also greatly suppressed demonic power. When the Three-legged Demon Bull’s demonic power clashed with the thunder-infused Sword Qi, it only held for a moment before faltering.

The Thunder Sword Qi exploded on the body of the Three-legged Demon Bull, its scales emitting black light in an instant, blocking part of the divine might of the thunder and avoiding instant death. However, it was severely wounded, with smoke rising from its body, most of its scales fallen off, and two of its four horns broken.

The Three-legged Demon Bull scattered its hooves and ran towards the woods, knowing it was no match for the man before it and could only flee.

"Where do you think you’re going!"

Su Chengyu pursued the bull on his Sword Control flight, and the bull, already injured, could not run fast. Soon, Su Chengyu caught up, and with a sweep of azure Sword Qi, he chopped off the remaining two horns of the Demon Bull. The bull roared in anger and continued its flight.

With a point of his left hand, Su Chengyu released the Ruyi Golden Ring, trapping the Three-legged Demon Bull on the spot, immobilized. Then, he took out the God-Destroying Bow, nocked the bow, and shot The Arrow of The Bow of God Destructor, striking the bull’s head and piercing it through. The body of the Three-legged Demon Bull collapsed thunderously to the ground.

Su Chengyu flew to the side of the Three-legged Demon Bull’s corpse and extracted the Demon General’s Inner Pill.

"Give that inner core to me," demanded the Heaven-Mending Stone as it came out to claim its spoils of war and, incidentally, swallowed the corpse of the Three-legged Demon Bull.

"The Demon General’s Inner Pill isn’t much use to you. I’ll refine it myself. Here, I have a Demon King Inner Core that I forgot to give you," said Su Chengyu to the Heaven-Mending Stone, not being stingy and tossing it the Demon King Inner Core he had acquired from trading with the Beitang Clan.

"You little rascal, you had a Demon King Inner Core and didn’t bring it out sooner."

The Heaven-Mending Stone unceremoniously accepted the Demon King Inner Core and continued, "I sense that a powerful beast has arrived; you’d better leave quickly."

Not daring to linger, Su Chengyu leaped up and disappeared into the dense forest after a few bounds. Less than two minutes after Su Chengyu’s departure, a lion with golden fur emerged from the woods.

This Golden Lion, with two heads, was a descendant of the ancient Ferocious Beast, the Nine-Headed Golden Lion.

The Two-Headed Golden Lion looked around, sensed the residue of a presence in the air, and snorted, "The scent of a human, has the Kunwu Realm opened again? Doing the math, it doesn’t seem to be the time for it to open yet."

The trial in the Kunwu Realm was an opportunity for people to seek fortunes, acquiring the inner cores of Beasts as well as various treasures. Meanwhile, for the indigenous Beasts of the Kunwu Realm, it was a chance to feast. The opening of the Kunwu Realm was also a carnival for the native Beasts.

The Two-Headed Golden Lion saw no trace of humans around and started to leave as well.

Since he was unfamiliar with the situation in the Kunwu Realm, and the number of powerful Beasts on this sea island, he did not rashly run about anymore. After killing the Three-legged Demon Bull, he found a cave to temporarily reside in, planning to refine the inner core of the Three-legged Demon Bull first, and together with the over two thousand Heavenly Pills on him, his Realm could be raised another level.

The trial of the Kunwu Realm lasted a full six months, and Su Chengyu was not in a hurry, since this was just the beginning.

Refining the inner core of a Demon General was not difficult for Su Chengyu, who was in the Tongxuan Realm, unlike the cautious approach needed when refining the inner core of a Demon King, to prevent being backlashed by demonic power. The inner core of the Three-legged Demon Bull brought his Realm close to the peak of the Second Layer of Tongxuan Realm. After that, he consumed more than two hundred Heavenly Pills before finally advancing to the Third Layer of Tongxuan Realm.

Although Heavenly Pills were very suitable Elixirs for cultivation, eating too many reduced their effectiveness. After reaching the Third Layer of Tongxuan Realm, Su Chengyu did not continue cultivating; otherwise, with the Heavenly Pills he had, advancing to the Fourth Layer of Tongxuan Realm would not be a problem at all.

"I still need to refine higher-level Elixirs to benefit my cultivation more."

The nature’s spiritual energy in the Kunwu Realm was incredibly abundant. He believed that there must be mystical objects within that could not be found in the outside world.

Su Chengyu stepped out of the cave and continued to explore the sea island. He applied an invisibility charm to himself to hide his aura. Beasts were very sensitive to human scents, and without hiding his aura, he would easily be discovered by Beasts.

On his way towards the center of the sea island, he encountered some Beasts, but their Realms were not high, and they were weaker than the Three-legged Demon Bull he had encountered earlier; they did not pose any threat to him.

The sea island was not very large, and after one day of exploration, he had basically figured it out—the most powerful creature on this island was the Two-Headed Golden Lion, at the Demon Emperor Stage.

A Demon Emperor was equivalent to Nascent Soul Realm, before which Su Chengyu would be instantly killed in a single blow, even with the help of the Heaven-Mending Stone, he was no match for the Two-Headed Golden Lion, so Su Chengyu did not dare to provoke it.

The Two-Headed Golden Lion lived in a huge cave in the center of the island. Su Chengyu stood on a large tree and looked from a distance. There were glimmers of light inside the cave, suggesting that there were treasures in there, but he did not dare to get too close.

Su Chengyu silently withdrew and found a safe place to start practicing Qingcheng Mountain’s Thirty-Six Heavenly Qi-breaking Swords. There wasn’t much of value on this island, and he did not plan to stay long. He intended to leave after mastering the sword technique and explore other sea islands.

Two more days passed, and Su Chengyu’s Thirty-Six Heavenly Qi-breaking Swords had made small achievements. With a gesture of his Sword technique, thirty-six Dragon Slayer Swords materialized behind him, each wielding unparalleled sharpness and power.

He visited the lair of the Two-Headed Golden Lion again, where the Golden Lion was just lying in the cave, sleeping, with most of its head exposed.

"It’s strange, though," he murmured, "once the Kunwu Realm begins, these native Beasts should be on the move, hunting humans all around. Why is this Two-Headed Golden Lion still deep in sleep inside the cave, hardly moving an inch?"

As he stroked his chin, Su Chengyu speculated inwardly.

At that moment, the Heaven-Mending Stone lazily spoke up, "It must be guarding some mystical object inside the cave, something that requires its constant vigilance, preventing it from leaving. Ask around carefully, can you smell a faint fragrance wafting from the direction of its lair?"
