"Fifth-level backtracking technique..."

Qingxu's eyes fell on the backtracking technique and frowned slightly: "The cooling time has actually increased from twenty-two and a half hours to twenty-four hours? It's exactly two days, but this change... can you choose the backtracking time yourself?"

This effect cannot be said to be good or bad.

The previous retrospective technique had to wait for twelve hours before it could be activated. Now, after a change of change, you can choose the time to go back. That is to say, even if he just used the retrospective technique, he could restore his body state to before the retrospective technique in the next second, and there was no need to wait for twelve hours, and the operability increased significantly.

It’s like he used the sword intent to sharpen his spiritual level, and often he could only hold on for less than half an hour. After half an hour, his soul disintegrated, and for the next eleven and a half hours, he wasted eleven and a half, almost a day, and the current retrospective magical changes are gone.

Also, if he is fighting a life-and-death battle with an opponent, both of them will be in a loss. If he can restore his state to the peak by relying on the backtracking technique, he will be able to kill the opponent immediately. However, the backtracking technique of the backtracking technique will be twelve hours later. When his backtracking technique is activated, the opponent will have no idea where he has gone, or with the help of various external forces to restore his characteristics, he will restore his state as before, making him regret it.

Now the backtracking technique is controllable, which also perfectly solves this disadvantage.

Another point...

It was just being squatted by someone else.

Anyone who knows the backtracking technique understands that the backtracking time of the backtracking technique is twelve hours, and this is easy to target by people based on this time.

One kills multiple goals.

"The fifth-level backtracking technique is already like this. I really don't know what changes will happen when the backtracking technique is promoted to the sixth level. In addition, any skill will have a new change after reaching the tenth level. How mysterious will the tenth-level backtracking technique be derived?"

Qingxu was a little fascinated.

However, now he plans to use the 126 Dao Rhymes to avoid being able to survive by upgrading the level of chaos when he encounters life danger. The other hundred Dao Rhymes are intended to be used to practice and reverse Yin and Yang.

The inverted yin and yang are related to the secret of one's whereabouts. Once you reach the realm of great success, even the sword-holder who holds his spiritual imprint may not be able to lock in his direction and descend to the main battle incarnation to kill him. In this way, it is enough to be foolproof.

"The backtracking technique has come, and the transformation realm has been completed. Then... you can try to condense the fusion reactor in your body and impact the realm incessantly."

Qingxu pondered, constantly recalling the relevant knowledge about nuclear fusion that he learned back then.

At the same time, he also took out the Burning World Art and deeply understood the various descriptions of the Uninterrupted Realm in this magic formula by understanding the practice methods in the Burning World Art.

"It's OK to give it a try."

A flash of light flashed in Qingxu's eyes.

The next moment, his figure flashed and appeared in the courtyard.

Seeing Qingxu appear, a guard from the Qingming Realm level immediately greeted him outside the courtyard and saluted respectfully: "Master Yuqing."

"Um?"

Qingxu glanced at the Qingming Realm guard, and he felt a little strange.

After all, he was the benefactor who saved Su Yuan and restored Su Yuan's mind. Why did Su Xiao, who used the guard to protect him, actually have the Qingming Realm?

However, when he felt that there was no cultivator above Qingming Realm in the entire courtyard, he thought of something and asked, "What happened?"

"this……"

The Qingming Realm Guard hesitated for a moment and replied: "It's Beiyue Peak. Beiyue Peak sent people to intercept the goods of our Shenhui Chamber of Commerce for four consecutive times, and took out the goods to sell them openly in the trading market under Beiyue Peak. The goods are very important to our Shenhui Chamber of Commerce. The young lady personally led a team of masters to secretly protect them, preparing to teach those who dared to intercept the goods of our Shenhui Chamber of Commerce a lifelong lesson."

"Didn't the strategy of the Shenhui Chamber of Commerce always focus on defense? Now that it is full of people, aren't it afraid of Beiyue Peak's plan to lead the snake out of the cave?"

"I don't know this at all. The young lady probably has already investigated it and is sure to be foolproof."

Qingxu nodded after hearing this.

Although he intends to interfere in the affairs of the Tibetan Sword Continent, the Tibetan Sword Continent is not the Eastern Wilderness World after all. In the Eastern Wilderness World, he is already powerful enough to suppress all forces by one person, the Tibetan Sword Continent...

At least if the strong man from Beiyue Peak comes out in full swing, he will never be able to resist it.

Besides, Shenhui Trading Company has not yet reached its impending moment of destruction. Even if he wants to take action, he has to wait a little longer. Only when Shenhui Trading Company is completely desperate can he take action again to obtain the greatest benefit.

"Do you know about the nearby terrain? I need a practice experiment in a rare open space."

"Empty and uninhabited land..."

The Qingming Realm Guard pondered for a moment and immediately thought of something: "You may as well go to the Emerald Swamp 6,000 kilometers away. Although the Emerald Swamp is not a large swamp, it is also 800 kilometers in radius. Moreover, since there are no specialties inside, there are a large number of scorpion crocodiles that are equivalent to the second-level level, basically no one will stay in that area."

“Emerald Swamp.”

Qingxu nodded, and finally said to the Qingming Realm guard: "You might as well tell President Su Xiao that if she really has no way to think about it, she might as well send me a message. Maybe I have a way to save the Shenhui Chamber of Commerce."

The Qingming Realm Guard was slightly stunned.

After getting along during this period, they have already understood that although Qingxu has achieved cultivation, it is not as good as the veterans of the Shenhui Chamber of Commerce in the Continuous Realm. How could they be the opponent of Beiyue Peak, who has several powerful Jindan realm masters?

This is also the reason why Su Xiao never asked Qingxu to take action even if the situation in the Shenhui Chamber of Commerce is in crisis for a month.

But the other party was kind-hearted after all, so he had to promise: "I will convey these words to the young lady."

Qingxu nodded, jumped up, broke through the sky with his sword, and in the blink of an eye it turned into a stream of light and flew towards the emerald swamp.

Stepping on the Flowing Fire Sword and feeling the storm coming towards him, Qingxu couldn't help but sigh: "The flying sword also needs to be changed. Although the level of the Flowing Fire Sword reaches the top level of the ninth level, it is completely suitable for my current cultivation level. Even most of the Flying Swords who are from ordinary Jindan realm are still only at the ninth level... But... I have always relied on the advantage of flying swords when fighting with people. If I can buy a top level of ten-level flying sword, the possibility of winning when facing the powerful Jindan realm is much greater."

However, flying swords are different from magic weapons and powerful weapons. The price of flying swords is often much higher than magic weapons and powerful weapons.

It is easy to sell an eleventh-level magic weapon with a tenth-level flying sword.

Therefore, if Qingxu really wants to buy a top-grade tenth-level flying sword, at least he has to prepare hundreds of things that carry the Tao. Even if he encounters a seller who is eager to take action, there is probably no hope without dozens of Taoist rhymes.

"I remember the last time the Divine Punishment was sold before it was destroyed by our sky. At that time, the top-grade flying sword of the tenth level required only thirty rhymes, and the bottom-grade divine weapons of the twelve level were willing to sell 100 rhymes... Unfortunately, at that time, I didn't have any rhymes on me and I never caught up with such a rush to buy... It seems that people have to pay more attention to the movements in the Chaos Temple recently. Once a chaotic organization is facing the Chaos Battle, it will take many magic weapons and weapons, and the 126 rhymes that are reserved for use in my hands will be useful immediately."

Qingxu thought to himself that he had projected a spirit into the Chaos Temple and conveyed his instructions directly to Yan Huang, Xin Long, Ling Yue and others.

They can't help him at all at the combat level now, but it's still quite useful to find out the news as the Son of Chaos.

After two hours of flying with the sword, Qingxu appeared in the Emerald Swamp.

This swamp is just like the Qingming Realm guard said, it is simply a forbidden area for life. Because it is filled with a large amount of poisonous fog and ferocious beasts, let alone the awakening realm, the true Qi realm powerhouse, even if the strong man in the refining realm is not careful, he may fall into this swamp. As for the mortals below the awakening realm, they will die as many times as possible.

Qingxu searched in the sky and soon stopped at a relatively high place. Then he flipped his hand and shot out the six array flags, covering the radius of ten kilometers.

These six array flags are not a great treasure, but are just one of the treasures collected in the Xuanmen of Creation. With the array flag, a formation that confuses others and has a warning function can be derived. The formation is not powerful, and the True Yuan Realm power can be broken by a little bit of hands and feet. It is far from comparable to the Forbidden Xu Xuan Formation, but it is more than enough to be used as a warning.

After setting up the formation, Qingxu landed on the ground and soon fell into contemplation: "The most important factor in nuclear fusion is gravity, or high pressure, and in addition, it is temperature. The critical temperature of complete nuclear fusion reaches 40 billion degrees. Even if the Burning World Art I practiced is extremely domineering, it cannot heat its own energy elements to this level. Moreover, the temperature of complete fusion burst far exceeds a hydrogen bomb. Therefore, complete fusion is obviously not advisable. It can only use the tunnel effect to reduce the fusion efficiency, and gradually test the limits I can bear now."

After repeating the plan in his mind, a glimmer of light flashed in his eyes.

The next moment, the retrospective technique is activated, and then the strong and violent force in the body begins to operate at an extremely terrifying speed and accelerate. Under his extremely precise control, trace elements begin to break out from the elemental core. Simply put, the electrons outside the nuclear energy are separated from the nucleus, and the two nuclei are attracted and collided to each other to undergo a nucleus polymerization. During this collision and polymerization process, a large number of electron neutrons break away from the nucleus, forming an energy fluctuation and releasing to the surroundings, forming a terrifying torrent of energy!

And because two atomic nuclei are mutually polymerized from one atomic nucleus to another, a new atomic nucleus is born and can regenerate with other atomic nuclei again, and continue to release energy, repeating over and over again, endless!

This is the principle of the fusion reactor.
