Seeing this, Gu Yu smiled and said, "It's right to be strong, but you kid don't be too ambitious either.

This technique is not that easy to practice. Every time you go to the level, the spiritual energy you need will be increased ten times.

Moreover, the process of bodybuilding is not so pleasant, it is like a burning fire, and it is extremely painful."

"If the foundation is not solid, then it will not be the phoenix that will be reborn from the ashes, but will be burned into ashes by the fire."

Hearing this, Chen Fei's face was solemn, nodded, and said, "Auntie, I remember, I will be careful."

Then, Chen Fei asked carefully, "Ancient, what level have you practiced in this Nine Phoenix Nirvana Sutra?"

When asked this, Gu Yu felt a little moved, sighed, and said leisurely: "I have practiced this technique hard for so many years, and in the end I can only barely enter the sixth level.

The seventh floor, with my qualifications, I can say that I have no hope for life."

“The sixth floor!”

Chen Fei felt a little emotional, and at the same time he showed a hint of doubt. He looked at Gu Lao and asked, "Gu Lao, you are so strong.

How could we be locked up here? Can we break the dungeon and escape together?"

When Gu Lao heard this, his face slightly darkened and he sighed: "This matter has been a long story.

At the beginning, too many things happened and too many people involved.

When the time is right, I or your master will tell you."

"As for escaping! My strength is no longer much lower than before, and I cannot break the cage."

Ancient words, some regrets and disappointments.

Chen Fei pursed his lips, feeling a little unwilling, gathered his true energy and blew down at the special railing of the cell.

However, a layer of light flashed on the railing, dissolving Chen Fei's attacks.

The railing remained motionless without any damage.

Afterwards, Chen Fei tried several more times, but even if he used the martial arts in the Dan core, he could not break the railing.

In the end, there was no way, Chen Fei could only say goodbye to the ancient, return to the previous stone chamber, take a deep breath, sneak into the dark red water surface, and start to return to the original route.

"Slam" and Chen Fei came out of the spiritual spring.

There was silence around. Chen Fei took off his coat and was still quietly lying around the spiritual spring without any change.

It seems that no one came here, and no one noticed that Chen Fei had ever penetrated the spring and reached the dungeon.

Of course, it is normal to think about it.

After all, this is the forbidden Tianluo Spirit Spring in Tianluo Palace, so no one dares to come here casually.

Originally, Chen Fei's body had reached a limit, but now that he had obtained the "Nine Phoenix Nirvana Sutra" from Gu Yu, Chen Fei was not in a hurry to leave.

He was immersed in the spiritual spring again, recalling the Nine Phoenix Nirvana Sutra in his mind, and began to practice carefully.

I have to say that Chen Fei has a good understanding, and the Nine Phoenix Nirvana Sutra is somewhat related to the Nine Yang Burning Heaven Decision that Chen Fei has practiced.

So, Chen Fei soon got started and began to practice the first level of the Nine Phoenix Nirvana Sutra.

According to the description in the exercises, Chen Fei used the spiritual energy in his body to temper his physical muscles.

The first thing he tried was the muscles on his right hand.

Control the muscles here and absorb the spiritual energy in the body.

Not long after, the muscle cells that had absorbed enough spiritual energy began to swell, heat up, and even became hotter, as if they were burning.

For a moment, Chen Fei couldn't help but have an illusion that his right hand seemed to be burned by fire.

An indescribable sense of severe pain spread from his right hand to Chen Fei's brain, causing Chen Fei's cheeks to twitch violently, and he couldn't help but take a deep breath.

Although he was ready after hearing Gu Yu's words.

But when this painful feeling of body refining really happened, Chen Fei almost cried out in pain.

He hurriedly used the wood meaning and emitted a cool and gentle breath, easing the pain of muscle cells in his right hand.

In this way, Chen Fei's muscles on his right hand used the spiritual energy in his body to burn and exercise himself, while constantly absorbing the spiritual energy and entering his body.

I don’t know how long it took, but after Chen Fei finished his first practice of the Nine Phoenix Nirvana Sutra, he almost fell into the spring without losing his energy.

After a while of slowing down, Chen Fei finally recovered.

He raised his right hand and looked in front of him, but it seemed that there was no difference. He could not see any abnormality from his appearance.

However, Chen Fei gathered his strength slightly, looked forward, and punched him straight out with a punch.

Suddenly, a powerful physical force came from his right hand.

The fist hit a hard stone beside the spring water, and with a bang, it smashed the stone directly into a pile of powder.

"This power!"

This scene made Chen Fei happy and showed an excited expression on his face.

Although with his strength, crushing a stone is not surprising at all.

But the current situation is a little different.

Because, his punch only had the strength of his body and did not use a trace of true energy.

Moreover, even the power of the body was not used, but just a random punch.

But with little force, the hard stone was smashed into powder with a fancy punch.

This is enough to show that Chen Fei's right hand is extremely powerful at this moment.

If he punched out with all his strength, Chen Fei would even be confident that he could really smash a hill with one punch.

Thinking of this, Chen Fei was extremely excited.

"The Nine Phoenix Nirvana Sutra is indeed magical!"

Excited, Chen Fei did not waste time. He hurriedly held his breath and concentrated his mind, practiced the Nine Phoenix Nirvana Sutra again, tempering other parts of his body.

In this way, under the double attack of pain and excitement, Chen Fei practiced tirelessly in the spiritual spring.

A week later, Chen Fei slowly opened his eyes in a burning and painful feeling.

Just a simple standing movement made Chen Fei stagger and almost fell to the ground.

However, Chen Fei soon adjusted and stood steadily in the spiritual spring.

He knew that this was caused by the increased physical strength and some of the situations that were not suitable.

After moving his body for a while, Chen Fei felt that his body was full of strength, as if he was about to explode from his body.

He knew that this practice should have reached a bottleneck.

It takes a period of time to refine and allow the body to adapt to digest these forces before further practice can be carried out.

"This time, I've gained a lot!"

Chen Fei looked full of joy and walked out of the spiritual spring.

And when he walked around, he realized the abnormality.
