Lu Yong left the hall and was led to the secret realm.

There is a place in the secret realm that has been specially divided, and there is a simulated warehouse with a very high sense of technology.

Academician Li was busy outside the simulated warehouse, his eyes were bloodshot, and you can imagine how long he had been working.

"All I'm going to do is eat this, walk in, and start practicing, right?"

Lu Yong was holding a pill, which was refined for him by the secret realm, which allowed him to quickly gather spiritual energy, and the effect was much stronger than that of the little ginseng, but the cost performance was too different.

Academician Li nodded: "There is another point, after you enter the simulation warehouse, it is possible to encounter life-threatening dangers, but this can also stimulate your potential to the greatest extent, so that you can comprehend the exercises, have you thought clearly?" ”

Lu Yong didn't hesitate at all, and his short body got into the simulation warehouse.

"Let's get started."

Academician Li was stunned for a moment, then clenched his fists, he took a deep breath and said, "Start mobilizing fire aura and simulate the volcanic environment!" ”

……

By the next morning, when Mu Chen opened his eyes, the Dragon Kingdom team had already sent him a projection.

The cultivation method of the Fire Control Technique that has been optimized has been improved all the way to the fourth layer!

A trace of shock flashed in Mu Chen's eyes, even if he was a genius in the sky, he was afraid that he wouldn't be able to reach the fourth layer overnight, right?

"Everyone is working so hard, how can I fall behind?"

Mu Chen spent an hour practicing, and then hurried towards the crater with his head held high.

When he rushed to the crater, the two people from the Hundred Battle Gate and Li Yao had already arrived.

Li Yao still looked like he was underbeaten, and he looked at Mu Chen with disdain:

"What kind of hero am I? I'm afraid I almost didn't get up when I went back yesterday, right? ”

Mu Chen still just treats him as air, and the best way to deal with this kind of person is to slap him in the face with action!

Of course, the most important thing is that private fights are not allowed here, otherwise Mu Chen would have to throw him into the crater.

Mu Chen began to cultivate cross-legged, today's communication was extraordinarily relaxed, and his body not only had no pain, but also was very comfortable.

"The fourth layer of "Fire Mastery" is really extraordinary!"

Generally speaking, Condensing Realm cultivators like Mu Chen and them could only penetrate the Fire Control Technique to the third layer at most.

The method is actually a demonstration of the laws of the Great Dao of Heaven and Earth, and the realm determines the monk's perception of the Great Dao.

Only after reaching the Jindan period and having contact with the Great Dao of Heaven and Earth can you comprehend the next layer.

But it's not the same as the Vulcan Body!

What is an anti-heaven constitution? That's breaking the mold!

You can't take it for granted!

With the help of Lu Yong's strength, Mu Chen cultivated to the fourth layer of the "Fire Control Technique" in just half a day.

At this moment, he could no longer feel the rejection of him by the fire aura, but began to manipulate the fire aura, refining his body and eliminating impurities.

Flame is the best choice for refining the essence in this world.

Useless impurities will be incinerated to ashes.

And the Wanli Jinpeng transformation seems to work quite well in a harsh environment.

It's just that after half a day, Mu Chen feels that his physique has doubled again!

He felt that he could now blow Zhou Lang's Jindan with one hand.

Moreover, he also felt that the fire aura around him was gradually unable to meet his needs for quenching, and could no longer bring him improvement.

"I need a more powerful stimulus!"

Mu Chen's eyes flashed as he stared at the magma in front of him.

Li Yao suddenly let out a long roar: "Haha, Lao Tzu has finally reached the second layer, and by tomorrow, I will definitely be able to break through to the third layer!" ”

As he spoke, he looked at Mu Chen with very provocative eyes.

Mu Chen seemed to be pondering something, and he suddenly stood up and walked towards the crater.

His actions also caught the attention of the other three.

"What? Hit stupid by me? Thinking about suicide? ”

Li Yao said very insidiously, he really wished that Mu Chen would jump down.

The king was kind and persuaded: "Don't be anxious, there is still one day to go!" ”

Mu Chen asked her a clueless sentence: "How many zhang can the fairy dive now?" ”

Wang Bu was stunned, and another male cultivator from the Hundred Battles Gate replied: "Both of us can dive fifty-five zhang, but as time goes by, the distance we can dive every day is also shrinking. ”

Mu Chen nodded, pinched the magic technique, and a black-red spiritual power shield instantly enveloped him.

Li Yao jumped up directly in shock: "Impossible, how can you ......"

Before he could finish speaking, Mu Chen had already jumped into the magma.

Li Yao took a step back, his face instantly turned pale, his lips trembled, and he kept repeating:

"He has a six-grade spiritual root, how could he be, he is just a six-grade spiritual root......"

The two monks of the Hundred Battles Gate also glanced at each other in surprise, and hurriedly stepped forward to explore the crater.

"What kind of monster is this guy......" The corners of Wang Bu's eyes twitched, she had already been hit very hard here, but she didn't expect to be hit by Mu Chen, a guy with miscellaneous spirit roots, today.

The two of them have just reached the third layer of the first grade spiritual root!

……

Beneath the magma, Mu Chen's vision was completely covered in crimson, and he couldn't see anything at all.

His heart moved, and he let go of his senses, which made him feel better.

However, the fire aura in this magma was too strong, and the divine sense could only detect the situation around a few zhang.

Mu Chen manipulated the aura shield to keep descending, and with each drop point, the pressure on the aura shield increased by one point.

Mu Chen dropped about thirty zhang, and the pressure he was under here should be his limit, so he began to temper his body here.

The fire aura, which was ten times crazier than the outside, entered Mu Chen's body, once again allowing him to experience the heart-rending feeling of yesterday.

Mu Chen hurriedly took out the Tianyun wine gourd from the storage bag and took a sip, and the blood in his body immediately seemed to be ignited, and began to be presumptuous in Mu Chen's body.

But Mu Chen just wants these fire aura to be presumptuous in his body!

Destroy the weak! to be reborn stronger!

Wanli Jinpeng changed his full strength, and the skin on Mu Chen's body cracked like a dry riverbed.

It didn't take long for Mu Chen's whole body to be like a clay sculpture, covered with a shell.

Mu Chen shook his body, and these "shells" fell off one after another, revealing the golden skin inside.

"I didn't expect that the Jinpeng change would actually change in this kind of place!"

Mu Chen stripped off his clothes and sat naked in the shield.

Such restrictive footage naturally cuts off the live broadcast to the public.

Mu Chen's whole body seemed to be covered with a film made of gold, which looked sacrosanct, he shook his left hand vigorously, and suddenly felt as if he had the power to crush heaven and earth.

He had a faint feeling that something was calling out to him beneath the volcano.
