After leaving the Southwood City, Ye Xiao once again arrived at the secret location from where he got his hands on the Golden Brick.

This time, when he entered into the dark tunnel, he changed the formation that was placed on the big round rock so that except for him, no one else can enter here after all to devour the four corpses of fifth-grade magical beasts, no place can be better than this one.

Here, no one will disturb him. He not only wanted to increase his strength, but he also wanted to cultivate the first level of the Myriad Fire Image Technique to its peak so that he can have one more trump card in his hands.

Ye Xiao sat down on the ground cross-legged and took out one of the four corpses of the Fifth Grade Magical Beasts.

He did not know exactly how much time it would take him to devour the four Fifth Grade Magical Beasts but he knew that it will definitely not be a short period of time.

"Devour!"

He placed his hands on the corpse and started devouring while circulating the First Layer of the Nine Dragon Universal Circulation Technique.

As he devoured the corpse of the magical beast, the amount of spirit energy within his body also started to increase rapidly.

Not long after, Ye Xiao's spirit energy had nearly doubled in amount within his body compared to before. He did not stop but continue to devour. But the spirit energy within his body looked as if it stopped increasing after doubling in the amount.

He was surprised to see this so he looked inside his body and followed the path of the spirit energy and to his surprise, he discovered that the Dragon-Shaped Core within his dantian was absorbing the spirit energy nonstop that he was devouring from the corpse of the magical beasts.

Because of this, he remained at the First Stage of the Origin Core Realm and did not achieve a breakthrough in his cultivation.

"What is happening? This never happened before!" Ye Xiao was shocked to the extreme but soon he discovered that as the Dragon-Shaped Core was absorbing the spirit energy, the Heaven Devouring Divine Dragon within his sea of consciousness was also becoming larger and larger in its height.

The aura of the Heaven Devouring Divine Dragon was also increasing continuously. Its aura was already frightening but now it was becoming more and more fearsome.

Time continues to pass. He had long devoured the corpse of the magical beast to the point where it became a very skinny dried-up corpse. But even so, he failed to breakthrough. It has to know that this corpse of a magical beast was actually a corpse of a Fifth Grade Magical Beast.

Ye Xiao immediately took out another corpse of the Fifth Grade Magical Beast and continue to devour it. This time, after he has almost done devouring the second corpse of the Fifth Grade Magical Beasts, the Dragon-Shaped Core stopped absorbing the spirit energy.

Ka-cha!

When he completely devoured the second corpse, a sound of something breaking rang out inside his body. Ye Xiao felt as if some type of shackle has broken inside his body and soon his body automatically started to absorb the spirit energy from his surrounding.

"Second Stage of the Origin Core Realm."

Ye Xiao opened his eyes and took a long breath while feeling the changes within his body.

"My strength... It seems even stronger than when I was at the Fourth Stage of the Origin Core Realm! Why is that?"

Ye Xiao felt that he was now even stronger than before. He did not know the reason behind it but he guessed that maybe it was related to the Dragon-Shaped Core within his dantian.

He did not stop here, he once again took out another corpse of the Fifth Grade Magical Beast and started devouring it.

Because of the ability of the Heaven Devouring Divine Dragon, even if he increased his strength continuously by four or five stages, his foundation will remain strong. It looked like a magical ability but it was true.

This time, the Dragon-Shaped Core did not absorb the spirit energy that he devoured so his strength started increasing with a frightening speed. Very soon, he once again reached the peak of the Second Stage of the Origin Core Realm and felt that he was going to breakthrough to the next stage.

If he were to enter into the next stage of the Origin Core Realm, he has no idea how much his strength will increase.

"Buzz!"

He continues to devour the corpse and circulate the First Layer of the Nine Dragon Universal Circulation Technique at the same time.

At this time, Ye Xiao had already completely released all the restrictions he had on the spirit energy.

"Boom!"

A burst of horrifying aura shook the circumference of fifty meters and everything within this area started to tremble. This aura actually burst out from within Ye Xiao's body. The ground was even cracking and its might was so vast that it violently fluctuated.

"Third Stage of the Origin Core Realm!"

Ye Xiao once again broke through and advanced to the Third Stage of the Origin Core Realm. And exactly at this time, the corpse of the third Fifth Grade Magical Beast completely dried-up.

Phuu!

Ye Xiao let out a breath of air from his mouth.

"The requirement to make a breakthrough is getting more and more difficult. Even after devouring three corpses of the Fifth Grade Magical Beast, my strength only increased by two stages. There is only the last corpse of a Fifth Grade Magical Beast left in my spatial ring. I just hope that it can help me to breakthrough to at least at the Fifth Stage of the Origin Core Realm."

Ye Xiao muttered in his heart as he took out the last corpse of the magical beast from his spatial ring. It was the corpse of the big black bear.

It looked like that all of this happened in a very short period of time but the truth was that almost it took him more than a week to devour the three corpses of the Fifth Grade Magical Beasts.

Ye Xiao adjusted his position, then once again placed his hands on the corpse of the big black bear and started devouring it.

"Devour!"

His strength once again started increasing at a very fast speed. Early Third Stage, Medium Third Stage, and soon his cultivation increased to the Peak of the Third Stage of the Origin Core Realm without stopping.

After his cultivation reached the Peak Third Stage of the Origin Core Realm, it stopped increasing as if it has encountered some type of bottleneck.

"Bring it on!"

Ye Xiao shouted and forced the spirit energy to circulate faster and faster inside his body.

"Rumble!!"

It was like a thunderbolt.

The spirit energy within his body seemed to have been completely released as it fiercely roared out. The moment that spirit energy, which had become like a wild horse escaping its reins, was forced, it began to move ten times faster than normal and it moved to every inch of Ye Xiao's muscles and meridians as fast as lightning!

"Ahh!"

Such a powerful circulation instantly started to destroyed Ye Xiao's meridians, causing him to groan out in pain. If it was not for his astonishing willpower, he would not have been able to withstand it!

"Shuu!"

Boundless amounts of spirit energy continue to flow inside his body.

"Break!"

Ye Xiao's blood started to boil at this moment as he shouted loudly.

"Boom!"

An explosion sound rang out and a trace of blood could be seen at the corner of Ye Xiao's mouth which started to flow out the moment he shouted.

But as if Ye Xiao did not felt it, his mouth curved slightly as he let out a comfortable smile.

"Fourth Stage of the Origin Core Realm!"

Finally, he once again arrived at the point where he previously was.

"Why is it getting more and more difficult for me to breakthrough?" Ye Xiao noticed that as he continue to breakthrough, it is getting more and more difficult. This time, even blood flew out from the corner of his mouth. And its reason was something, Ye Xiao did not know.

Ye Xiao did not think too much about this, he once again closed his eyes and started to devour again.

He had already made up his mind that he will breakthrough to the Fifth Stage of the Origin Core Realm. So, even though he faced great difficulty in breaking through to the next stage of his realm, he did not stop.

Time continues to pass hour by hour then day by day and his strength also continues to rise.

Soon, he once again increased his cultivation to the peak of the Fourth Stage of the Origin Core Realm.

And now it was the time to make another breakthrough!
