For Chu Xun, every minute and every second of time is precious, so after returning to Cape City, Chu Xun also took action immediately.

Since Zhou Yulong was in retreat and cultivating with all his might, Chu Xun couldn't contact him at all. In desperation, Chu Xun could only enter the second world, bring out the doctor, Carmela and others, and let them negotiate to deal with the matter.

At the same time, Chu Xun also passed Emperor Xu's request to the speaker through special channels, waiting for the speaker's decision.

Facts have proved that the request made by the Void Emperor is not excessive, and even in many ways it is in line with the interests of the entire human race. Therefore, after a series of discussions, the doctor and others finally made a decision, that is, to agree to Emperor Xu's request.

However, after all, the Killer Guild and the Void Emperor are the existence that people fear, and in order to avoid unnecessary trouble, the Void Emperor was not sent by the Speaker and others to fight in the Inner Earth, but was left in the human world. In this way, it can prevent Zhou Yulong and others from not daring to go all out when fighting because of guarding against the Void Emperor, and secondly, they can also use the power of the Void Emperor and the killer to protect the human domain and balance the Southwest Alliance.

In this way, it is equivalent to eliminating the worries of Zhou Yulong and others. After all, there is a void emperor, and the fallen dragon must not be able to make any ghosts.

……

Chu Xun did not participate in this discussion, but after delivering a part of the elixir to Kwai Shui, he re-entered the second world and began to retreat and practice penance, striving to condense the golden law before the battle for the center of the earth began.

"Devouring metal?"

Looking at the gold-devouring insect in his hand that was constantly struggling and wildly waving its insect feet and pincers, Chu Xun squinted his eyes slightly, then took a deep breath and shook it hard with his right hand.

Click!

Although the body of the Gold Devouring Worm was extremely strong, it was only a larvae after all, how could it be able to resist Chu Xun's terrifying power?

I saw that with a crisp cracking sound, the tough golden armor on the gold devouring insect was also crushed by Chu Xun's huge force. Then, streams of brilliant golden light also burst out from Chu Xun's palm and merged into his body at an extremely fast speed.

And with the influx of the genetic power of the gold devouring insects, Chu Xun's body also began to bloom with a little bit of golden light. Under the shining light of this golden light, Chu Xun looked like he was wearing a set of gilded battle armor, which looked particularly magical.

Buzz!

However, this was only the beginning, and the next moment, the golden light surrounding Chu Xun's body began to tremble and hum. And under the trembling and humming of this golden light, an unprecedented sense of hunger and thirst also emerged from the bottom of Chu Xun's heart. Prompted by this feeling of hunger and thirst, Chu Xun subconsciously began to use the homology technique to collect the surrounding metal energy towards him.

Chu Xun was originally the master of this second world, and here, he had an affinity for the elements of each system far beyond others. Coupled with the effect of the homology technique, it was almost just a blink of an eye, and golden streamers condensed from all directions and merged into Chu Xun's body at an extremely fast speed.

With the integration of a large number of metallic elements, the strong sense of hunger in Chu Xun's body suddenly weakened a lot. At the same time, Chu Xun could also clearly feel that the continuous influx of gold elemental power was being integrated into every part of his body under the action of the gold devouring insect gene, making his muscles, bones, and even nails and hair more tough and sharp.

Soon, Chu Xun found that his nails began to shine like a metal blade. Then, curiously, he stretched out his thumb and middle finger and flicked it gently with the nails of both fingers.

Boom!

In an instant, a sound of metal rubbing like sharp blades rubbing against each other also sounded, and between Chu Xun's two nails, there were even sparks that flickered due to the violent friction.

Obviously, under the influence of this metal element, his physical strength has reached a higher level than before!

And more importantly, this is just the beginning. As time passed, more and more metal elements were incorporated into his body, which would definitely further enhance his strength.

Thinking of this, Chu Xun also meditated and retreated again, and began to absorb the power of the metal elements in the second world with all his might, hoping to condense the golden law as soon as possible.

However, it turned out that after fusing many ancestral witch law phases, Chu Xun's difficulty in fusing law phases at this moment was far greater than at the beginning. Even if he had the genetic help of the gold devouring insect at this moment, he could continuously absorb and assimilate the power of metal, but Chu Xun still found that the speed at which he fused this golden law phase was almost overwhelming.

At this rate, I'm afraid that he may not be able to condense the golden law before launching an attack on the inner world, let alone circulate the five elements to invoke the power of the second world.

Thinking of this, Chu Xun suddenly had a headache.

How can we further accelerate the process of condensing the golden dharma?

However, soon, Chu Xun got inspiration and inspiration from Zhou Yulong.

As far as he knew, Zhou Yulong was an extremely rare metal mimic ability, and this ability called "metal mimicry" was simply like the liquid metal robot in the movie "Terminator", which could be ever-changing and exert extremely strong combat power.

However, while this ability is powerful, it is also extremely difficult to cultivate and advance. In order to obtain enough metallic power, Zhou Yulong even began to devour various high-level alloys everywhere like this gold-devouring insect, and then decomposed these devoured alloys, and finally increased his ability strength by absorbing the decomposed metallic power.

Thinking of this, Chu Xun also had an idea.

Perhaps, he can also strengthen himself by devouring metal like Zhou Yulong. After all, isn't that what this gold eater worm does? There's no reason why you can't do this by fusing the genes of the gold-eating insects......

Subsequently, Chu Xun also returned to Cape City and managed to get various alloys. And as it turned out, his conjecture was correct. After fusing the genes of the gold devouring insects, Chu Xun's body seemed to have a strong ability to absorb metal. Even the hardest steel, when Chu Xun put his hand on it, it would melt like encountering high temperature ice and snow, and finally it was completely absorbed by Chu Xun's hands.

And after absorbing these high-grade alloys, Chu Xun could also feel an extremely powerful metal force pouring into his body. After all, by doing so, he was reversing the process of "elemental materialization" and re-dividing the metal substance into a powerful metallic force, so that the speed of improvement would naturally be much higher.

But how can the truth be as good as expected, Chu Xun found that although the metallic power obtained by devouring metal in this way is powerful, the metallic power needed to condense the law phase of gold is even more amazing. Unless he could obtain an infinite number of high-grade metals, the high-grade metals that Cape City now had would not be able to support his condensation of gold in any case.

In desperation, Chu Xun could only use various channels to purchase a large amount of high-grade metals with heavy money, while he himself returned to the second world while the major forces helped collect high-grade metals, and used the power of metals in the second world to further improve himself.

Time is running out, and he can only do his best in both ways.

I have to say that the bounty given by Chu Xun is tempting enough. Under the temptation of Chu Xun's high bounty, the price of high-grade metals in the entire human domain was also rising, and those who were originally frantically looking for suitable Zerg also began to look for suitable metals instead.

After all, this thing can be found much easier for the Zerg!

As a result, with the efforts of the major forces in the human domain and many powerhouses, a large number of high-grade metals began to be transported in Haijiao City every day. These high-grade metals were often classified by the staff arranged by Chu Xun, and then put them into the spatial portal that Chu Xun had always kept open in order of the highland of value, providing a lot of resources for Chu Xun's cultivation.

With the help of these many rare metals and high-grade metals, Chu Xun, who was already able to mobilize the power of powerful metals for his own use, also began to cultivate at a speed of thousands of miles a day. And with the integration of this large number of metal elements, Chu Xun's body became more and more tenacious and sharp, like a divine weapon that had been continuously refined and polished.
