This belief is so pure that he can maintain the highest degree of concentration, independent of external circumstances.

This state is very, very difficult to achieve.

For example, people admired the warrior Qiu Shaoyun, but they couldn't understand how Qiu Shaoyun endured the great pain caused by his body being on fire, and remained motionless from beginning to end, but Qin Tian could fully understand it now.

Qiu Shaoyun's belief at that time was to sacrifice himself and not let the troops be exposed, for this belief, Qiu Shaoyun could endure the greatest pain of being burned alive, and he didn't move when he was burned alive, and used his life to save the troops and not let the troops be exposed, thus winning the victory of the troops.

Of course, compared with the state he is in at the moment, compared with the state Qiu Shaoyun is in, he is definitely not as noble as Qiu Shaoyun, the other party sacrificed for the sake of revolutionary beliefs, but in essence, it actually shows the impact of faith on a person.

A strong belief allows people to persevere even in absolute danger.

The temperature in the room is getting higher and higher, the air is getting thinner and thinner, if it is someone else, it has collapsed at the moment, and it will fall into a panic, either cursing endlessly, or slamming the door frantically, although Qin Tian is also in pain and sweating, he does not stop contemplating the fourth tone of the world.

"Damn, it's still now, Qin Tian is still cultivating Sonic Gong."

Shi Poyun was furious.

He had already used up almost a ton of wood, and the bluestones around the gate had been softened, and the temperature in the closed room had exceeded at least sixty degrees Celsius, but Qin Tian didn't even scold him, he was concentrating on cultivation.

Of course, he knew that Qin Tian must have relied on cultivating sonic skills to find a way out, but he thought that he couldn't do the same as Qin Tian in this situation.

"Damn. Isn't the air inside consumed? ”

Shi Poyun cursed and threw a large bundle of wood into the fire, and the flames jumped higher.

He needed Qin Tian to die immediately, it was best to hear Qin Tian's heart-rending screams, and only by confirming that this strongest opponent was dead, he could feel at ease.

Therefore, he didn't have the heart to search for treasures in other places in the World Destroying Mansion at all, and he was thinking about killing Qin Tian first and then talking about the rest.

In his mind, Qin Tian had actually become an existence similar to a "brain tumor", he was deeply affected and had to be cleared before he could recover.

"The combination of sound and qi is a very incredible thing in itself, but the World-Destroying Venerable has done it, and I have now touched some doorways, but something went wrong in the middle of the way, so I can't send out lightning."

Qin Tian thought to himself, and he didn't stop trying for a moment.

In fact, now, his throat was already hoarse, and he could cough up a large cloud of blood when he stopped and coughed casually, but his mind was highly concentrated, and he didn't pay attention to this, including his body being scorched by the heat.

Qin Tian continued to try again, and found that after the sound wave and the Gang Qi were combined, it came out of his mouth, only half of a lightning bolt was formed, and it was fleeting, but at this time, the aura in his mind suddenly flashed, and he grasped the most important point.

"Yes! I didn't do a good job here, and it was only with a single hair that I moved my whole body, so that the complete lightning could not be sent! ”

"Try again!"

Qin Tian's mouth opened, and this time, a complete lightning bolt came out of his mouth! Even though the lightning bolt is small, only as thin as the little finger, and it is also very short, the sign of the fourth tone of the world is "lightning and thunder", which means that he has entered the door!

At this moment, he also grasped many essences of sound wave changes, which he could not comprehend before today.

It's like going to school and studying, before the teacher teaches him a new knowledge point, he can't use the new knowledge point to solve the same exercise, but as long as he learns in class, even if he only learns a little bit, then at least when facing the same exercise, he has a different way of thinking.

And before you learn, you can't think differently at all.

The principle is the same.

Qin Tian mastered some of the essence of sound wave changes, and when he went back to learn the third tone of the world, he immediately found that the third tone still had defects when he learned it, and now he was able to make up for these few defects!

"Great!"

Qin Tian's heart was surging, and he immediately let out the third sound "Hiss"!

Sure enough, after trying, he found something, so he immediately corrected it, and after it was issued again, the power of the third tone of the world was significantly increased, and Qin Tian also had a hearty feeling.

The slight obscurity that I felt when I heard the third note before is completely gone at this moment!

Qin Tian knew that the third tone had finally come to pass!

First tone, second tone, third tone, all of them!

He thoroughly mastered the three tones before the destruction of the world.

"It's time."

Qin Tian stood up, and after his consciousness returned to paying attention to himself, he found that the temperature in the room was very high, so stuffy that it could make people faint, although he had already used the Nether Treasure Armor to protect his body, which could isolate the high temperature, but he was still affected by the extremely scarce air, and it was seriously difficult to breathe.

It is estimated that in another ten minutes or so, he will not be able to hold on.

And he only has one chance, if the three tones of the destruction can't cause some kind of change, then he is bound to die here.

Although he is not afraid of death, he is confident that he is a good man after eighteen years, but in the end, who is stupid and wants to die, not to mention anything else, the revenge has not been avenged, and the ancient Han Xiao of Chixiao Xuanmen has not been killed!

Qin Tian adjusted for a moment, and finally sent out the three tones of extinction.

Chemical element!

Phew!

Pyrimidine!

For the first time, Qin Tian used the three tones of the complete Dacheng World Destruction to send out a sonic attack!

Burst!

The super sonic resonance spreads inside the closed room, because the sound wave cannot spread quickly to the outside, so the whole room is the echo of a huge sound wave, which continues to stop.

The bronze door was closed, but there was still the tiniest gap between the bottom and the ground, and a very small part of the sound wave ran out of this crack, but it was such a tiny amount of sound wave, and after rushing outside, the vertical burning flame suddenly spread backwards, like a fire snake.

Shi Poyun was taken aback when he saw the fire snake spread more than ten meters and pounced towards him, although he dodged it easily, he was very surprised.

"Damn, what's going on?"

Discovering this change, Shi Poyun's face was very unsightly.

Qin Tian made such a big commotion, could he really find a way to break open the room and get out?

Swish!

Shi Poyun drew out the Purple Sun Sword and waited for it.

As soon as the bronze door was opened and Qin Tian had just shown his head, he would immediately attack. Anyway, Qin Tian must not be allowed to leave alive.

The longer Qin Tian grows, the more he is afraid that it will not be long before his strength will surpass him. He would not allow such a strong opponent to exist.

Inside the room, Qin Tian's Dacheng's world-destroying three tones emitted a huge sound wave like a terrifying wave, and Qin Tian himself was actually suspended by such a huge sound wave, as if he was being pushed by a huge wave in the ocean, up and down!

"There must be a change."

Qin Tian observed his surroundings, desperately hoping that something would change.

Whether it succeeds or not, whether it survives or not, it all depends on the next one.

His heart was as stable as Qin Tian, and he was also a little nervous.

The Venerable of the Destruction of the World hides the secret of the Eight Sounds of the Destruction of the World, so he should not be mad, and he will really come out of a Jedi and trap the person who receives the inheritance to death, right?

It can be guessed that this is the guess, but Qin Tian doesn't know what the result will be.

Do your best, obey the destiny of heaven. This is the truest portrayal of him at the moment.

Buzz, buzz.

Suddenly, Qin Tian seemed to hear an extremely subtle humming sound from the sound wave, the sound was too small, and the difference was extremely difficult, he couldn't be sure, but he caught a glimpse of the ground changing.

The ground that was originally paved with cyan stone slabs was now in an area about the size of two millstones in the center, and a little starlight appeared, accompanied by a humming sound, and then the starlight quickly formed a text.

Qin Tian hurriedly got out of the sound wave float, stood on the ground, and read this text.

This article is narrated in the form of classical Chinese, and the general idea is easy to understand.

This passage is the self-description of the Venerable Exterminator, who said that he had been pursuing the limit of martial arts all his life, and he did not hesitate to spend his whole life in penance, and had obtained a lot of treasures, martial arts, and exercises, but after he reached the realm of Wuzun, he was finally unable to break through to the mysterious realm above Wuzun, and came here to build the Extinction Mansion at the end of his life.

There is only one thing that is valuable in the World Destroying Mansion, and that is the cultivation method of the five tones after the destruction of the world. There are a lot of martial arts in the world, but I don't think there is any need to keep anything else, just leave the world-destroying eight tones that I am most proud of.

Because, the Eight Sounds of Destroying the World is a king-level martial art created by him, and after learning the eighth tone "Destruction", he will have the ability to reach the sky, and once the Eight Sounds of Destruction come out, he can kill the strong of Wuzun!

Therefore, he didn't leave anything in the World Destroying Mansion, but this martial art couldn't bear to be lost, so he hid it, hoping that someone with a great opportunity could inherit it.

"It turns out that it's really the World-Destroying Venerable."

After reading this text, Qin Tian sighed in his heart.

At the end of this text, there is a slightly smaller font, which roughly means: Those who are destined only need to accept the inheritance of the Eight Sounds of the Destruction of the World, and do not need to be involved with the Venerable of the Destruction of the World.

The implication is that there is no need for people who are destined to pay anything, as long as the eight tones of the world are passed on.

"It seems that the Venerable of the World Destroying really doesn't want to lose the Eight Sounds of the World."

"And from this passage of his text, it can also be seen that he has a strong confidence in the Eight Sounds of the Destroying World, and he can leave nothing else, except for this martial art."

Although the World-Destroying Venerable said that he didn't need anyone who was destined to give anything, Qin Tian still folded his hands and bowed to the ground, expressing his respect for the World-Destroying Venerable.

What Qin Tian didn't expect was that after he completed this action, this text composed of starlight quickly disappeared, and then there was a clicking sound in the room, Qin Tian looked back, and found that on the stone wall next to the door, a one-inch-long stone handle popped up!

Qin Tian was sure that he had carefully inspected it, it was obviously solid, and the density of the material was the same as that of other areas, so it was impossible to hide a mechanism at all, but now that he saw it with his own eyes, he could only sigh that this was a powerful means left by the World Destroying Venerable.

As a martial venerable powerhouse, the means left behind by the World Destroying Venerable were not visible to him as a heaven-level master, which was also normal.

Qin Tian was excited.

The appearance of the stone handle means that the open mechanism has appeared!

Holding the thing in his right hand, Qin Tian directly pulled the stone handle!

Click, click!

As if a winch was spinning slowly, the gate slowly moved to one side, and a blazing fire poured in through the exit.

In the firelight, Qin Tian could clearly see the stone breaking clouds outside the flames.

Of course, at this moment, Shi Poyun also discovered him.

"How so? Ahhh ”

Shi Poyun saw that the gate was reopened, and Qin Tian saw the light of day again, his expression was distorted with irritation, and he hurriedly sent out a gang qi to desperately hit the mechanism that had been destroyed outside the gate, trying to make the gate close again, but it was useless, the gate was not under his control, and continued to push it open slowly.

Qin Tian's figure flashed, he came out of the fire directly, and fell ten meters away from Shi Poyun, and the Colorful Divine Cone was facing Shi Poyun!
