In the next few days, Chu Xun almost stayed in the heavy truck that Optimus Prime had transformed, on the one hand, gradually adapting to his soaring spiritual power, and on the other hand, he also cooperated with some of Optimus Prime's detection and inspection abilities to analyze and test his plague power.

Thankfully, his plague power, though powerful, even terrifyingly lethal and contagious, was just as contained in his blood, as acidic as his blood, and could not be transmitted through saliva, breath, or even sweat, as he feared most.

Otherwise, then he really wouldn't be close!

At the same time, Chu Xun also deeply felt that it was necessary for him to find a weapon master to tailor a suitable set of high-level weapons for him. After all, after not being able to enter the combat form, his defense and melee combat power have been reduced a lot, and if he can have a set of high-level weapons that suit him at this time, it will definitely be able to play a big role.

You must know that some high-level weapons are not only strong in defense, but also can have the effect of amplifying the elemental attack ability like the thunder weapons of Zhang Xie and others, and can even use this to improve their reaction speed and attack power, which can be described as infinitely useful.

And after having high-level weapons and further improving his combat power, he can also try to avoid being forced out of the demonized clone to fight.

Anyway, before finding a way to control the demonized clone, Chu Xun really didn't want to release this terrible murder weapon that only knew about killing, and was even very likely to hurt his own people!

Chu Xun's sleepless practice along the way finally had a certain effect, and by the time he rushed back to the ice city, he had been able to initially adapt to his surging mental power. Although it can't be meticulous in terms of control, and it can't be compared with those old mental powerhouses, at least there is no need to worry about being too emotional and causing mental power to go berserk, so that it will accidentally hurt others.

……

After arriving at the Ice City, Chu Xun put away Optimus Prime and walked towards the Ice City on foot.

"It's like a world away......"

Looking at the huge and towering walls of the Ice City, Chu Xun suddenly recalled the shocked appearance he had when he saw the Ice City for the first time, and then couldn't help but shake his head and laugh.

The ice city is still the ice city, but Chu Xun is no longer the original Chu Xun. After personally destroying the Dead Soul City, which has a population of more than 10 million and is even larger than the Ice City, the Ice City can no longer make him feel the slightest shock and pressure.

It's just that although Ice City is slightly inferior to Dead Soul City in terms of scale and population, the thriving, prosperous and energetic atmosphere in Ice City is much better than the gloomy and lifeless atmosphere of Dead Soul City and Blood Bone City.

Only such a city is full of life. Instead of those cities in the corpse realm, although the humans in the city are alive, they are like walking corpses, without the slightest human dignity.

"Did you hear, the annual sky auction has been rescheduled, and it will start in 15 days!"

"Why did this year start so much earlier than usual?"

"It seems that the Aegis family and the Fallen City have joined forces to come up with something new, so I contacted the other three major families and opened the sky auction in advance, ready to make a big profit!"

"What is it that makes them go to such great lengths to make such a big deal of money?"

"I don't know, but there seems to be some news on the market, saying that it is a cross-era invention that can completely change the way humans fight and the composition of their strength, which sounds quite mysterious."

"If it's true, then the Aegis family and the fallen city are probably going to be in the limelight, and even their patriarchs, Lord Qin Pojun and Lord Fallen Dragon, will have a great deal of power to speak in the Supreme Council."

"I think so...... In short, this sky auction will definitely be very lively! ”

……

Just when Chu Xun came to the Ice City Airport, preparing to take the next flight to Sky City, the sound of some people's conversations also came into his ears.

After many evolutions of the insect ability, Chu Xun's perception has become extremely acute, so although the voice of those people's conversations is small, he can hear them clearly.

"Castle in the Sky auction?" Hearing the conversation of those people, Chu Xun's eyes suddenly lit up.

He was worried that there was no good way to make a name for the panacea, and promote it and sell it at a good price, but he didn't expect that someone would send a pillow when he fell asleep. When it comes to the promotion effect and the ability to attract gold, I am afraid that nothing can compare to the annual sky auction.

The Sky Auction is the largest auction in Sky City, and the auction items are not only from the major families of Sky City, but also from various cities in the Human Domain. Once these cities have acquired some treasures that are incredibly valuable but not easy to sell, or that no one in the nearby cities can afford, they will hand them over to the bounty unions in each city, which will then evaluate them.

Among the relatively low value, the bounty union will purchase them at a relatively reasonable price, while other truly rare and precious items will be escorted to Sky City by the Bounty Guild, and then participate in Sky City's annual sky auction, whichever is higher.

Don't underestimate this Sky Auction, he not only gathered the top treasures from all over the human realm in Sky City, but also brought huge wealth to the five giants jointly organized. After all, although the 10% handling fee does not seem like much, the total value of the auction items in each Sky Auction exceeds more than 1 billion standard crystal nuclei, and this money is a lot of wealth even if it is evenly distributed among the five major families.

Of course, most of this wealth will be spent on the auction itself. After all, for the five major families, there are many treasures worth fighting for at the auction.

So this time, he had to find a way to use the elixir as an auction item in the Sky Auction no matter what!

After making up his mind, Chu Xun also stepped on the next flying machine to fly to Sky City and entered Sky City.

……

"What, he's not dead?"

Chu Xun didn't know that when he stepped on the flying machine, the verification system of the flying machine also transmitted the information he registered to Sky City, and quickly spread through some special channels.

And at this moment, the "shadow" of the Aegis family was looking at the message from his subordinates, and roared with an ugly face: "Didn't you say that there is no news of him in any city in the human domain, and it is suspected that he has been teleported to the corpse domain, how can he come back!" ”

After Chu Hang and the others returned to Sky City, they immediately reported the news of Chu Xun's disappearance to the speaker and the doctor, and asked for their help.

After getting the news, the doctor naturally used all the intelligence networks of Dragon Castle to search for Chu Xun's whereabouts in various cities. However, to the surprise of Chu Hang and others, the speaker did not hesitate to help them with all his might, and even used his authority in the bounty union to search for Chu Xun's whereabouts as much as possible by issuing a task to find Chu Xun in the bounty union in each city.

But more than ten days have passed, but they still have no exact news about Chu Xun, only some specious and even random clues. But even so, Chu Hang and the others did not hesitate to follow these clues to search for Chu Xun's whereabouts in various parts of the human domain, even if there was only a glimmer of possibility, they did not give up.

It's just that the great crisis in the human realm is all over the place, coupled with the misdirection of some well-intentioned people, they are also frustrated in the process of searching for Chu Xun, and some people are even deeply injured and have to return to Sky City to heal.

So, later, almost everyone thought that Chu Xun was dead, and Shadow naturally thought the same.

It's just that he never expected that at this moment, this guy who everyone thought was dead would step on the flying machine to enter the sky city so magnificently, and it is estimated that it will not be long before he officially enters the sky city.

"No, this person's potential is too great, and he must be eliminated immediately!" After the initial shock and anger, the shadow quickly calmed down, and a cold murderous intent flashed in his eyes.

There are no impermeable walls, and while he is confident in the secrecy of his work, he is equally aware of the abilities of the Dragon Castle and the Speaker. As long as they want to check, then sooner or later they can find out that Lan Qingkong was sent by their Aegis family.

If Chu Xun was just a penniless kid, then he wouldn't worry about anything, but judging from the strength that Chu Xun is showing now, the amazing growth rate, and the relationship with Dragon Castle and the Speaker, if he continues to let Chu Xun grow, then I'm afraid that Chu Xun will sooner or later become Qin Zhan, and he, and even the biggest enemy of the entire Aegis family!

After all, judging from this guy's past achievements and methods, he doesn't look like a "bad good person" who repays his grievances with virtue!

So after a few moments, Shadow made a decision, then took a deep breath and pressed a wrist communicator on his wrist.

Then, a holographic projection screen also shot out from the wrist communicator and appeared in front of him.

In the picture, there is a figure wrapped in a black robe, unknown male and female. There was nothing strange about this figure, but there was a strange pattern embroidered on the black robe on his body. The pattern looked like a blade dripping with blood, and underneath the blade was a hideous skull. The skull was opening its mouth wide, as if waiting for the blood from the end of the blade to drip down.

Knowledgeable people will be shocked if they see this mark.

Because this mark is the dark force that is almost as famous as the Supreme Council and the Bounty Guild, the Killer Guild!
