When both Ye Xiao and the poisonous beast arrived in front of each other in an instant, Ye Xiao slashed down his sword on the poisonous beast's head with his full strength.

"Clang!"

The sound of a metal collision rang out in his surrounding. Because Ye Xiao attacked with his sword first, the poisonous beast did not have the chance to attack.

"Srrr!"

When his sword landed on the poisonous beast's head, green blood gushed out from its head like a fountain.

"Zii! Zii!"

Ye Xiao flipped in the air and flew back. His sword was still stuck in the poisonous beast's head.

Not long after that, Ye Xiao saw a shocking scene. The part of his sword that was stuck in the poisonous beast's head actually melted down because of the terrifying poison. That terrifying poison acted as acid. And the other part of the sword soon falls down on the ground.

"This poison is so shocking!" Ye Xiao had no way to imagine how shockingly powerful the poison of this beast actually is. If it was him in the place of the sword, what would happen to him?

He could not help but tremble in fear of the poisonous beast's poison.

"Ziii!"

"Swish!"

The poisonous beast once again flapped its wings and flew toward Ye Xiao in rage while spitting out an arrow of poison from its mouth.

Ye Xiao also flew toward it while taking out another exactly same sword as the one which just melted down. Originally, what he got was the pair of a sword from the tomb of Mu Chen.

He turned aside and dodged the poison arrow and once again stabbed his sword down on the poisonous beast's head. This time, the poisonous beast becomes smart and immediately backed off.

It managed to avoid Ye Xiao's attack but Ye Xiao had also guessed that the same attack might not work on this beast as it was already a Fifth Grade Magical Beast which is about to become a Sixth Grade Magical Beast. It already has intelligence not inferior to that of an adult human.

Ye Xiao flapped his wings and with an increase in his speed, he once again appeared in front of the poisonous beast immediately and stabbed his sword on the wound of its head.

"Zii!"

The poisonous beast cried loudly in pain as the sword penetrated through its injured head. Ye Xiao did not stop here, he once again arrived in front of the poisonous beast, held its head from both sides with his dragon claws, and directly tore it open.

"Ziii!"

"Bang!"

The poisonous beast groaned loudly in pain and then fell down on the ground lifelessly. On the other hand, its green and poisonous blood scattered around everywhere in the circumference of one meter. Some of its blood also dropped on Ye Xiao's dragon claws as he used his two claws to tore open the poisonous beast's head.

He had no choice but to take the risk as this beast was actually very terrifying and if given any chance, it could instantly kill Ye Xiao. So, because he was wary of this beast, he took the risk and tore open its head.

When the blood of the poisonous beast fell down on his both claws, he was scared to the point where his mind went blank for a moment. He could not think of anything at this moment.

But then, he suddenly discovered that this poison actually did not affect his claws in any way.

Why is this?

When he thought about it, he guessed maybe it is because his claws came from the Heaven Devouring Divine Dragon. The dragon's scale that grew out on his hands when he transformed his hands in the dragon's claws, did not let the poisonous blood touch his skin and because of this, it did not affect him in any way.

"Thank god!" Ye Xiao heaved a long breath of relief when he found himself safe. He thanked God for this subconsciously.

After some time, Ye Xiao dragged the corpse of the poisonous beast out from the small and narrow cave. He was now preparing to devour its corpse so that he can break through to the Martial King Realm.

"Devour!"

Ye Xiao placed his hands on the corpse of the poisonous beast and started to devour it. Simultaneously, he also took out the pill that his master gave him and swallowed it.

"It is time to breakthrough!"

The energy contained within the pill was extremely violent. And at this moment, Ye Xiao was also devouring the poisonous beast which made the energy inside his body even more violent. However, right now, Ye Xiao did not think too much. He circulated the First Layer of the Nine Dragon Universal Circulation Technique and shaved off them bit by bit.

Once a small amount of energy was released, he started absorbing the energy into his stomach and started refining.

If it were a normal person, then doing something like this would be simply unimaginable because the energy within his body at this moment was really too terrifying. If a normal person had absorbed it like Ye Xiao, it was very likely that only a single strand would completely destroy their body.

But it did not affect Ye Xiao much as he circulated the First Layer of the Nine Dragon Universal Circulation Technique which is an unknown rank technique. With it, not only Ye Xiao was able to absorb this violent energy, but he was also able to refine it. He didn't even waste a single speck as he subdued the violent energy and refined it so that it could increase his cultivation.

In a situation like that, Ye Xiao's cultivation started growing rapidly. Although he was already a Peak Ninth Stage Origin Core Realm martial artist and was just half a step away from the Martial King Realm, this half step was still very hard to take.

To go from Origin Core Realm to Martial King Realm, one must experience a process that is like a river bursting out of a core.

"Boom!"

With an explosion, Ye Xiao's ordinary core in his dantian exploded and all the spirit energy within his dantian started to run havoc.

At the same time as the explosion, Ye Xiao's aura rapidly rose. It was extremely quick, and it was simply shocking.

"Ahh!"

Ye Xiao groaned in pain but he still did not stop and started to circulate the First Layer of the Nine Dragon Universal Circulation Technique with all of his strength, which slightly eased his pain.

As for Ye Xiao's aura, it had increased several times as his strength increased. That feeling was one of nearing the Martial King Realm. With one more step, he could step past the barrier blocking his way and become a Martial King.

Suddenly, with Ye Xiao as the center, spirit energy within several thousand miles, as if they were summoned, started quickly surging towards Ye Xiao's body and gathering around it.

At that instant, his aura was clearly different from before. There was a change, in essence, this... was the true power.

Ye Xiao could feel the changes that were happening within and outside of his body. The spirit energy from the world was entering his body as if he was a whirlpool sucking down everything that comes in contact with it.

The more he absorbed, the more he felt like absorbing the spirit energy. He does not know the reason behind it but his instinct told him to continue to absorb as much spirit energy as he could. He also felt as if fifty percent of the spirit energy that he absorbed disappeared after entering his body.

It was like, something or someone was stealing the spirit energy from his body rapidly. It was fortunate that there was no end of spirit energy here otherwise he would not be able to fill himself up completely.

Suddenly his dantian also started to expand, and only when it expanded to double its previous size, did it stopped expanding.

For most martial artists, advancing would only require breaking past a single barrier, which was often thought of as breaking out from a single pair of 'shackles'. Extremely talented people might have to break through multiple shackles. But no matter how talented someone was, to break through out of Origin Core Realm would definitely never double the size of one's dantian.

Only when a martial artist breaks through to the Martial Emperor Realm can their dantian expand in size. Before the Martial Emperor Realm, while breaking through, one's size could never expand but yes, the quality of the spirit energy within it will increase and grow denser and denser.

Just like when one breaks through to the Origin Core Realm from Qi Condensation Realm, their spirit energy's quality will increase as a core will form inside one's dantian.

"It is coming, it is coming!" Ye Xiao muttered excitedly as he felt his breakthrough is coming.
