Mu Yunfan subdued the spirit grass.

Suddenly, the spirit grass turned into wisps of extremely pure spiritual energy, and drilled into Mu Yunfan's body.

"What a rich aura!"

Sensing the huge aura, Mu Yunfan couldn't help but exclaim.

In his body, it was as if there was a volcano, spewing out aura frantically.

"Is this the speed at which a Yuanying realm cultivator absorbs the aura of heaven and earth?"

Mu Yunfan's eyes were full of amazement.

You must know that the aura contained in this spirit grass is only a little bit equivalent to the innate realm.

However, such a little aura can actually create a monk in the Yuanying realm, which shows the preciousness of this spiritual grass.

"Huhuhu~"

Mu Yunfan took a few deep breaths, and began to absorb the surrounding aura to replenish his consumption.

Soon, he realized that his strength had improved a little.

"It's worthy of spirit grass!"

Mu Yunfan praised.

He knew that the energy contained in this spirit grass was more precious than ordinary innate elixir, so it was like this.

However, he didn't know that the energy contained in this spirit grass was not as precious as he imagined, but it was a bit of a chicken rib, because the aura it contained could not make people advance to the Yuanying realm at all.

However, even so, it is absolutely impossible for a kid from the innate level to be promoted from the first level of the innate to the Yuan Infant realm, after all, he is not yet at the Yuan Infant realm.

Mu Yunfan's strength is not enough to support him, let him be promoted to the Yuanying realm, and his aura will not be able to withstand such a huge aura.

"It seems that my body still needs some special materials to withstand such a huge aura."

Mu Yunfan said secretly.

"Whew~"

He breathed a long sigh of relief and absorbed all the energy of this spirit grass.

Then, Mu Yunfan stood up, looked at the Black Tiger Demon King around him, and showed a bright smile.

"Hey, hey."

"Master, my strength has improved, and I can just try to break through to the peak of the innate second layer, or even go further!"

He clenched his fists, and his whole body was filled with strong fighting intent.

"Huh!"

He jumped up directly and landed on the ground, which was to start running the exercises in his body.

On the surface of his skin, a trace of lines appeared, exuding a faint silver light, like a silver net, all over his body.

"Hulala!"

In Mu Yunfan's body, there was a rattling sound, like a bell.

"Huh?"

"What's going on? Could it be because of the reason why I absorbed that spirit grass just now? “

"My body has actually changed, what is the situation?"

Mu Yunfan's eyes looked at his body in surprise.

At this moment, his whole body is like a silver god of war.

This change shocked Mu Yunfan to the extreme.

He had never been in this situation.

In the past, after absorbing the flesh and blood of spirit beasts and cultivating the "Nine Turns of the Yi Jin Sutra", the various attributes of his body reached a state of bottleneck.

However, this time, when he absorbed the aura of the spirit grass spiritual liquid, his body underwent a series of changes.

"Could it be that my body can also devour the flesh and blood of spirit beasts to increase my attributes?"

"If that's the case, that's good."

Mu Yunfan's heart was excited, his eyes were staring at his body, he was looking forward to his strength, and he made a qualitative leap again.

"Whoosh~"

Mu Yunfan's feet stomped on the ground suddenly, which immediately caused ripples, and the ground cracked several cracks.

His speed increased instantly.

In the blink of an eye, he came to the side of the Black Tiger Demon King.

He punched out.

The body of the Black Tiger Demon King was suddenly knocked away and smashed into the distance, blood flowing.

The Black Tiger Demon King's body, although it was seriously injured, still remained awake, and when he saw Mu Yunfan coming, he was immediately terrified.

His cheeks were even more distorted, and his voice was hoarse, and he roared: "Human, you dare to kill the demon king of our Black Tiger Demon Clan, you deserve death!" “

"Hmph, even if I'm going to kill you, what?"

Mu Yunfan glanced at the Black Tiger Demon King indifferently and said, "Didn't you say that you would kill me and then snatch the treasure from me?" Come on! “

"Human, you ......"

The Black Tiger Demon King's eyes were extremely resentful, looking at Mu Yunfan, wanting to say something.

But he was gagged by Mu Yunfan.

"Roar!"

Mu Yunfan raised his head to the sky and roared, with a hint of murderous intent in his eyes, and his palm waved out and slapped it fiercely.

"Boom!"

The body of the Black Tiger Demon King exploded again and turned into smithereens, leaving only a round golden pill.

"Haha, Jin Dan, it's finally mine."

A look of joy appeared on Mu Yunfan's face, and he reached out and grabbed the golden pill, and then put it in his mouth.

He felt the changes in his body, and his heart stirred.

"I didn't expect this spirit grass to have such a huge effect, after I absorbed it, it actually improved a lot."

"It seems that I underestimated this spirit grass before, but it turned out that it actually contained so much energy."

"Not bad, not bad, it seems that in the future, I will absorb some spiritual energy of the spirit grass, and the speed of cultivation will be accelerated."

Mu Yunfan's face was full of excitement, and his eyes rolled.

He carefully observed the changes in his body.

"Huh? Something is wrong, it doesn't seem that the changes in my body are due to the absorption of this spirit grass. “

Mu Yunfan narrowed his eyes slightly, and immediately, he saw that his body was constantly changing.

On his skin, a series of scale armor textures appeared, and these scale armors, like living creatures, slowly swam and exuded bursts of fluctuations.

Moreover, the muscles of his body have also become much harder.

His bones have also become stronger.

"It's ......"

Mu Yunfan's eyes widened.

He found that his physical body had transformed into a golden dragon.

It was a giant dragon, with golden scales all over it, like King Kong, and it was extremely strong.

"Hiss ......"

Mu Yunfan gasped.

"My body has transformed into a dragon?"

Mu Yunfan looked at this scene in horror.

This was only a first-order change, and he could be sure that if he took the Spirit Grass again, his body would definitely undergo a drastic change.

"No, I have to find a quiet place to practice."

Mu Yunfan immediately left the cave and walked outside.

His speed was extremely fast, and in a flash, he left the Black Tiger Demon Forest and entered the forest.

In the forest, there is abundant spiritual energy, and in this area, there are many demon beasts that can help Mu Yunfan cultivate.

However, Mu Yunfan did not choose to hunt demon beasts, but instead looked for a quiet valley and began a retreat, preparing to cultivate.

During this time, Mu Yunfan continued to devour the spirit grass, so that his body was greatly improved, so he was ready to take advantage of this time to break through to the foundation building realm.

Once he reached the foundation building realm, then he could use the fifth chapter of the "Dragon Imperial Technique" to cultivate the Dragon Elephant Gong to the fourth realm!

In this way, his strength will be greatly improved again.

Moreover, he also possessed a treasure.

This treasure is called the Aoki Sword.

This Aoki sword was a treasure weapon he had captured from the Black Tiger Demon King.

On the body of the Black Tiger Demon King, there is also a token.

In the token, the experience of the Black Tiger Demon King in cultivating the "Dragon Jue" is recorded, and this token can allow people to get some improvements in a short period of time.

However, the cultivation of the Black Tiger Demon King was too low, so this token did not have any effect.

However, even the content on this token is of great help to Mu Yunfan, which is enough to make Mu Yunfan's strength leap to a certain extent.

"Boom!"

Mu Yunfan sat cross-legged on the ground, and the black tiger phantom behind him exuded a terrifying coercion, causing the surrounding trees and flowers to sway.

The aura in his body frantically converged and entered the Aoki Sword.

The Aoki Sword emitted powerful fluctuations, fusing with the spiritual power in Mu Yunfan's body, causing Mu Yunfan's cultivation speed to skyrocket again.
