On the night of the fifth day, Chen Jiuyou sat alone by the reef of the hot spring and pondered.

After all, he has failed five times, no matter how strong Rao Shichen Jiuyou's will is, he will inevitably feel lost, after all, he only has five chances left, if Yan Wuji is telling the truth, then he may really die.

Under the threat of death, Chen Jiuyou racked his brains these days and used various methods, although he could survive the first three levels, but the thunder in the fourth level could no longer be spent by manpower, so he could only walk hundreds of meters in the past five days, and Chen Jiuyou could feel that the closer he got to the end of the cave, the more powerful the subsequent levels would be.

Although the situation was already so bad, Chen Jiuyou did not give up.

Yan Wuji arranged for him to clear the Vulcan Cave, there must be a deep meaning, and there must be a way to break the level, otherwise if Yan Wuji has the intention to kill him, it will be useless for him to resist.

It's just that he hasn't found the right way these days.

At this time, a figure came behind Chen Jiuyou.

Judging from the footsteps, Chen Jiuyou already knew who the person who came, it was Chen Yidao who came here with him.

Now, compared with before, Chen Yidao's body is much stronger, and his original fair skin has disappeared, replaced by a healthy wheat color.

Looking at Chen Yidao's puffy face, Chen Jiuyou was sure that this must have been beaten out by someone.

"You're much stronger than before, One Knife." Chen Jiuyou was relieved.

When Chen Yidao heard this, he couldn't help grinning, but then he seemed to think of something terrifying, and his face suddenly turned pale.

Chen Jiuyou saw the change in his face, he understood it very well, he also felt this way, the hellish tempering during this period of time was indeed like purgatory for them, hovering on the verge of death every day, but there was no doubt that their strength had indeed improved by leaps and bounds.

"Brother Chen, I see that you have been very ...... these days," Chen Yidao said worriedly.

"It's miserable, isn't it?" Chen Jiuyou laughed at himself.

Immediately afterwards, his mood became more and more depressed, and he couldn't find a way to solve it, and death was imminent, and he began to be anxious.

"Don't mention me, how are you now?" Chen Jiuyou changed the subject.

Chen Yidao said solemnly: "Senior Yan is very harsh, but I think he is for my good, although it is very hard, I can still persevere." ”

Then, he turned to Chen Jiuyou and smiled, "Since you can't resist, you can only try to adapt." ”

Hearing this, Chen Jiuyou's mind seemed to think of something, but he couldn't grasp anything, and hurriedly grabbed Chen Yidao's shoulder and said:

"Say what you just said again!"

Chen Yidao felt the strength on his shoulders and replied, "Don't resist, learn to adapt." ”

"That's right, it's ...... adaptation," Chen Jiuyou muttered, and suddenly exclaimed, "That's right! It's adaptation, why am I so confused, manpower is irresistible, why do I have to blindly resist? ”

Thinking of this, Chen Jiuyou's mind burst out with several spiritual lights, and he turned around and walked towards the house, he couldn't wait to think of a way to get through the difficulty.

Only Chen Yidao remained in place.

Seeing that Chen Jiuyou seemed to have thought of a way, and felt that he seemed to have accidentally helped Brother Chen, Chen Yidao revealed his innocence on WeChat.

.........

On the sixth day, Chen Jiuyou re-entered the cave that had failed him five times.

This time, Yan Wuji was no longer used to take him back, but he took the initiative to walk in.

As soon as he entered the cave, Chen Jiuyou instantly activated the [Ghost Shadow Trace], his body was like electricity, several afterimages flickered, and he ran for three hundred meters in one breath.

At this time, the sea of fire was already near.

Chen Jiuyou was like a moth to a fire, and threw himself into the flames without stopping.

Chen Jiuyou, who stepped into the sea of fire, immediately used the fire prevention technique taught to him by Yan Wuji, and instantly wrapped his whole body with a red film.

At this moment, Chen Jiuyou seemed to be like a fish in water, the violent flames were already difficult to hurt him in the slightest, coupled with the movement of the Heavenly Dome Sun Breathing Method in his body, he was extremely easy to adapt to the temperature of the sea of fire, and he could also draw strength from the flames.

The sea of fire, which could only be resisted, was so easily broken through by Chen Jiuyou.

At the same time, Yan Wuji, who was sitting in the crater, suddenly raised his head, his eyes seemed to travel through space, and he saw the scene of Chen Jiu's escape.

"I've finally found a little bit of a door, but it's not so easy next, you only have five chances left, can you seize it?"

With that, the volcano regained its calm.

At this time, Chen Jiuyou once again took this opportunity to rush forward for four hundred meters, and immediately equaled the distance he had reached for the fifth time.

The next moment, the blade of the wind was already in front of him.

Chen Jiuyou still chose to use [Ghost Shadow Trace] to dodge first.

The first few times, Chen Jiuyou also planned to use his body to dodge the wind blades that kept coming, but after that, there were more and more wind blades, dense, and they were no longer something that could be dodged by his body, so Chen Jiuyou could only use his body to resist after that.

But this time, the purpose of Chen Jiuyou's body technique is no longer to dodge, but to observe, he is observing the strength of the wind blade, the speed of the wind blade, and the rhythm!

Although the law of the wind blade is chaotic, each of its wind blades has its own unique attributes, and Chen Jiuyou is to find the characteristics of the wind rhythm from it.

For the previous sea of fire, Chen Jiuyou has a fire resistance technique to help adapt to the high temperature and scorching of the sea of fire, and in the Sword Wind Pass, Chen Jiuyou also has a similar help.

That's the [Wind God Legs]!

Although Chen Jiuyou had never learned it, he and Yu Baifei had honed their martial arts many times before, practiced together, and felt the wind god legs thousands of times, and he already knew about it.

It's just that because he already has a top-level body technique [Ghost Shadow Trace], he has never tried to use the Wind God Legs.

Raising soldiers for a thousand days and using soldiers for a while, the Chen Jiuyou version of the wind god leg launched, and the footsteps turned into afterimages, and rushed into the sword wind in an instant.

When he first entered, his whole body was already covered with scars because he was not adapted, but gradually, Chen Jiuyou quickly adapted to the wind speed and wind power, and began to slowly blend into the wind, no longer being carried away by the wind.

With the passage of time, Chen Jiuyou was even able to use the power of the wind to reverse the impact, and the blade-like wind blade was no longer able to hurt him in the slightest, but instead became his help.

Because of the blessing of the wind, Chen Jiuyou ran forward for a full 1,500 meters during this time.

This astonishing progress made Chen Jiuyou see the hope of victory.

Landing from the wind, Chen Jiuyou gasped for breath, after all, it cost a lot to break through two levels in a row.

And the next level, there is a volcanic ash tide.

In fact, this level depends on whether it can survive it, and the gray tide that spreads all over the cave cannot be avoided.

Under those highly toxic gases, whether you can survive is the key.

For this level, there is no longer the help of the exercises, and he can only rely on himself.

Soon, a rumbling sound came, and after a while, the gray tide had already come to the eyes, and it had already submerged Chen Jiuyou in an instant.

Chen Jiuyou quickly closed his breath, his body felt the scorching pain, and his lungs had already begun to ache.

He hurriedly adjusted the oxygen in his lungs and resisted desperately.

I don't know how long it took for the gray tide that implied to be highly toxic to gradually subside.

Although this volcanic ash tide contains many highly toxic gases, these poisonous gases actually do not harm Chen Jiuyou much.

There is a characteristic in the system that shows his special physique, that is, it is invincible.

These toxins have quickly been converted into zero force by Chen Jiuyou, and the most important thing in this level is the damage to the lungs caused by gases such as carbon monoxide.

After the gray tide completely subsided, Chen Jiuyou suddenly exhaled the air, exhaling the remaining poisonous gas in his lungs in one breath, and the exhaled gas at this time was actually black.

After the detoxification was completed, Chen Jiuyou ran forward again.

This time, Chen Jiuyou walked nearly 2,800 meters again, plus the previous one, he had already walked 5,000 meters.

At 2,800 meters, he experienced the attacks of the sea of fire, the sword wind, and the gray tide in turn.

And after these two cycles, he is about to face the strongest level, Thunder Hell.

Although he doesn't quite understand why this Fire God Cave is connected to the heavenly thunder, but the heavenly thunder and the earth are hot, and it is impossible to say whether the earth fire can hook the heavenly thunder.

This is a real thunderstorm, so under this heavenly power, it is no longer possible for human beings to get through.

Although it seems that it is impossible to pass, Chen Jiuyou still thinks of some methods, and now it is time to put it into practice.

Soon, the lightning was already in sight, and the sound had not yet come.

Chen Jiuyou hurriedly lowered his breathing, and the breath of the whole person slowly fell, as if it was about to disappear from here.

In the next second, the dense heavenly thunder had already submerged Chen Jiuyou.

Chen Jiuyou's body only lasted for tens of seconds, and then it was about to explode.

The hand that had come five times stretched out from the void crack again, grabbing Chen Jiuyou in.

The sky swirled, and Chen Jiuyou landed next to the hot spring.

This time, Chen Jiuyou didn't have any abnormal reaction, and he didn't seem to care about this failure, and even had joy in his eyes.

After reflecting on the experience and lessons he had just broken through, Chen Jiuyou stepped into the hot spring.

.........

On the seventh day, after walking 6,400 meters, Lei Prison Pass insisted on a tea time.

On the eighth day, after 7,300 meters, the Thunder Prison Pass lasted for half an hour.

On the ninth day, 8,200 meters were traveled, and the Thunder Prison Pass lasted for four-thirds of the hour.

As the days passed, Chen Jiuyou had already traveled 8,200 meters in the Fire God Cave.

Tomorrow is his last chance, and his last life, if he fails, he still can't reach the end of the Vulcan Cave, then he will also fall.

Chen Jiuyou probably guessed that the Vulcan Cave should be 10,000 meters deep, and he was already about to reach the end, only the last 1,800 meters.

During this period, Chen Yidao was very worried about whether Chen Jiuyou would be able to break through this Vulcan Cave, and pleaded with Yan Wuji many times, but Yan Wuji refused indifferently.

But to Chen Yidao's surprise, his eldest brother Chen was still in the mood to hum while soaking in the hot spring.
