"Fifth Order Backtracking ......"

Qingxu's gaze fell on the backtracking technique, and he frowned slightly: "The cooldown time has actually increased from twenty-two and a half hours to twenty-four hours? exactly two days, but this anomaly ...... Can you choose your own backtime?"

I can't say whether this effect is good or bad.

The previous retrospective technique had to wait for twelve hours before the retrospective technique could be activated, but now after giving birth to the mutation, he can choose the time of retrospection, that is, even if he has just used the retrospective technique, he can return his body state time to the time before the retrospective technique in the next second, without waiting for twelve hours, and the operability has greatly increased.

It's as if he sharpened his spiritual level with the help of sword intent, he could often only hold on for less than half an hour, and after half an hour, his soul collapsed, and in the next eleven and a half hours, he was in non-existence, wasting eleven and a half hours in vain, almost a day's time, and now the retrospective technique mutation is no longer this problem.

And if he is fighting to the death with an opponent, the two are fighting to lose, if he can rely on the retrospective technique to restore his state to the peak, he can immediately kill the opponent, but the retrospective technique time of the retrospective technique is twelve hours later, and when his retrospective technique is launched, the other party has already disappeared, or with the help of various external forces and recovery characteristics, he will restore his state to the same as before, so that he can regret it.

And now the time of the backtracking technique is controllable, which also perfectly solves this drawback.

One more point......

It's just being squatted by others.

Anyone who knows about backtracking understands that the backtracking time of backtracking is twelve hours, so it is easy to be targeted by people who set traps based on this time.

Kill more than one stone.

"The fifth-order retrospective technique is already like this, I really don't know what kind of changes will occur when the retrospective technique is upgraded to the sixth order, in addition, any skill will give birth to a new mutation after reaching the tenth order, and how mysterious will the tenth-order retrospective technique become?"

Qingxu was a little fascinated.

However, now he plans to use one hundred and twenty-six rhymes to spare, so as not to be able to survive by raising the chaos level when his life is in danger, and the other hundred rhymes are intended to be used to practice reversing yin and yang.

Reversing yin and yang is related to the secrecy of his whereabouts, once he reaches the realm of Dacheng, even the sword wielder who holds his spiritual imprint in the heavenly vault may not be able to lock his position and descend the main battle incarnation to kill him, so that it is enough to be foolproof.

"The retrospective technique has come up, and the transformation realm has been completed, so what is next...... You can try to condense the fusion reactor in your body and impact the endless realm. ”

Qingxu groaned, and kept recalling the knowledge about nuclear fusion that he had learned back then.

At the same time, he also took out the Burning World Formula, and through understanding the cultivation method in the Burning World Formula, he profoundly understood the various descriptions of the Endless Realm in this Method.

"You can try. ”

A gleam flashed in Qingxu's eyes.

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

Seeing the Qingxu appear, a guard at the level of the Qing Netherworld Realm immediately greeted him outside the courtyard and saluted respectfully: "Lord Yuqing." ”

"Huh?"

Qingxu's gaze swept towards this Qingxia Realm guard, and there was something strange in his heart.

He was also the benefactor who saved Su Yuan and restored Su Yuan's sanity, why did Su Xiao use the guards to protect him actually come to the underworld?

However, when he felt that there was not a single cultivator above the Qing Netherworld Realm in the entire courtyard, he seemed to think of something and asked, "What happened?"

"This ......"

The Qing Netherworld guard hesitated for a moment, but still replied: "It's Beiyue Peak, Beiyue Peak has sent people to intercept the goods of our Shenhui Chamber of Commerce four times in a row, and also took out those goods to sell in the trading market under Beiyue Peak, now this time the goods are very important to our Shenhui Chamber of Commerce, the eldest lady personally took a team of masters to secretly support, ready to teach those who dare to intercept the goods of our Shenhui Chamber of Commerce in Beiyue Peak a lesson that will never be forgotten for a lifetime." ”

"Hasn't the strategy of the Shenhui Chamber of Commerce always been based on defense?

"This is not clear to the subordinates, the eldest lady is estimated to have already investigated clearly, and has a foolproof grasp. ”

Qingxu nodded when he heard this.

Although he intends to meddle in the affairs of the Hidden Sword Continent, the Hidden Sword Continent is not the Eastern Wilderness World after all, the Eastern Wilderness World, he is already strong enough to suppress all the forces alone, but the Hidden Sword Continent ......

At least if the powerhouse of Beiyue Peak comes out, it will definitely not be something he can resist.

Besides, now that the Shenhui Trading Company has not yet reached the moment of imminent destruction, even if he wants to make a move, he has to wait a little longer, and only when the Shenhui Trading Bank is completely desperate can he make a move again, so that he can obtain the greatest benefits.

"Do you know the terrain nearby? I need an open place with few inhabitants to conduct a cultivation experiment. ”

"No Man's Land ......"

The guards of the Green Netherworld pondered for a moment, and immediately thought of something: "Your Excellency, you might as well go to the Emerald Swamp six thousand kilometers away, although the Emerald Swamp is not a large swamp, but it is also eight hundred kilometers in radius, and because there are no special products in it, and there are a large number of scorpion crocodiles equivalent to the second level, basically no one will stay in that area." ”

"Emerald Swamp. ”

Qingxu nodded, and at the end, he said to the Qing Netherworld guard: "You might as well tell President Su Xiao, if she really has nothing to think of, you might as well send a message to me, maybe I will have a way to save the Shenhui Chamber of Commerce." ”

The guards of the Qing Netherworld were slightly stunned.

During this period of time, they already understood that although Qingxu cultivated to attain it, it was not at the level of transformation realm, and it was not as good as those elders of the Endless Realm of the Shenhui Chamber of Commerce, how could it be the opponent of Beiyue Peak, which had several Jindan Realm powerhouses?

This is also the reason why even if the situation of the Shenhui Chamber of Commerce is in crisis again in a month, Su Xiao still did not ask Qingxu to take action.

However, the other party was kind after all, and he had to promise: "I will convey these words to the eldest lady." ”

Qingxu nodded, jumped up, and the sword broke through the air, and in the blink of an eye, it had already turned into a streamer and flew towards the emerald swamp.

Stepping on the Flowing Fire Sword and feeling the oncoming wind, Qingxu couldn't help but sigh: "The flying sword also needs to be changed, although the grade of the Flowing Fire Sword has reached the upper grade of the ninth order, it is completely suitable for my current cultivation realm, and even the flying sword used by most of the Jindan realm powerhouses from ordinary backgrounds is still only the ninth order...... But...... I have always relied on the advantage of flying swords when fighting with people, and if I can purchase a tenth-order high-grade flying sword, I have a much greater chance of winning against a strong person in the Jindan Realm. ”

However, flying swords are different from divine weapons, and the price of flying swords is often much higher than that of divine weapons.

A tenth-order flying sword can be easily sold for an eleventh-order divine weapon.

Therefore, if Qingxu really wants to buy a tenth-order top-grade flying sword, he has to prepare hundreds of rhymes to carry the Tao, even if he encounters a seller who is in a hurry to sell, it is estimated that there is no hope for a body without dozens of rhymes.

"I remember that the last time the Divine Punishment was destroyed by our Heavenly Dome, there was a round of fire sales, when the tenth-order high-grade flying sword only needed thirty rhymes, and the twelfth-order lower-grade divine soldiers were actually willing to sell one hundred rhymes...... It's a pity that at that time, I didn't have any Tao rhyme at all, and I didn't catch up with such a rush to buy event...... It seems that people have to pay more attention to the movements in the Chaos Temple recently, once there is really any chaos organization facing the chaos battle, a large number of divine weapons, and the one hundred and twenty-six rhymes in hand will come in handy immediately. ”

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

They can't help him at all at the combat level now, but having the identity of the Children of Chaos is still quite useful to find out the news.

Two hours after Edgeworth's flight, the ruins appeared in the Emerald Swamp.

This swamp is just like what the Qing Netherworld Realm guard said, it is simply a forbidden area of life, because it is filled with a large number of poisonous fog and fierce beasts, not to mention the powerhouses of the Awakening Realm and the True Qi Realm, even if the powerhouses of the Refining Gang Realm are not careful, they may fall into this swamp, and as for the mortals below the Awakening Realm, how many people will die.

Qingxu searched in the sky above, and soon stopped at a relatively high place, and then flipped his hands, and six array flags shot out, enveloping a radius of ten kilometers.

These six array flags are not a great treasure, just one of the treasures collected in the Xuanmen of Creation, relying on the formation flags, you can derive a formation that confuses others, and has a warning effect, the power of the formation is not strong, the powerhouse of the True Yuan Realm can break it with a little effort, it is far from being comparable to the Forbidden Void Xuan Array, but it is more than enough to be used as a warning.

Laying down the formation, the green ruins fell to the ground, and soon fell into deep thought: " One of the most important factors in nuclear fusion is gravity, or high pressure, and in addition, the temperature, the critical temperature of complete nuclear fusion reaches 40 billion degrees, even if the Burning World Technique I have cultivated is extremely domineering, I can't heat my own energy elements to this extent, and the temperature of complete fusion explosion is far more than a hydrogen bomb, therefore, complete fusion is obviously not advisable, I can only use the tunnel effect, reduce the efficiency of fusion, and gradually test the limit of what I can bear now. ”

After repeating the plan in his mind, his eyes lit up.

The next moment, the retrospective technique was activated, and then, the thick and violent power in the body began to run and accelerate at an extremely terrifying speed, and under his extremely precise control, trace elements began to detach from the core of the element, simply put, the electrons outside the nucleus were separated from the bondage of the nucleus, and the two nuclei attracted each other and collided with each other to cause nuclear fusion, and in the process of collision and aggregation, a large number of electron neutrons broke away from the nucleus to form energy fluctuations released to the surrounding area, forming a terrifying torrent of energy!

And because of the mutual polymerization of two atomic nuclei from one nucleus to the other, a new nucleus is born, and it can be re-integrated with other nuclei, and continue to release energy, and the cycle is endless!

That's how fusion reactors work.

It is also the key to Qingxu's stepping into the realm of endlessness.
