Seeing that those villagers went back to their homes, Lu Xiao controlled the ancient monks to put away the black metals, and asked the ancient monks to return to the city wall to guard, and then turned to study the soul core in the sea of knowledge.

Condensing the soul core is just the first step in practicing this soul devouring technique, and next, you must continue to improve your divine consciousness and nourish your soul with your divine sense, until you can sense the soul and use the soul core to devour it.

The soul is the most vulnerable place for a living being, as long as the divine consciousness is strong enough to break through the opponent's divine consciousness, and then the power of this technique is extremely huge, and it can kill people in an instant.

It's just that the soul is too mysterious, and no one in this monk's world has studied the magic power for the soul, and the magic power that Lu Xiao learned was also obtained from the strange creatures outside the territory.

Originally, with Lu Xiao's current ability, he couldn't even perceive where his soul was, and he didn't know that he needed to condense his soul and integrate it into the soul core, thinking that as long as he condensed the soul core, he would be done, and he almost caused a catastrophe.

Thankfully, the strange hand helped him, but at the same time, he also warned himself to build a teleportation array for him as soon as possible.

This has always been a difficult trouble in Lu Xiao's heart, he is afraid that he will suffer a catastrophe if he does not do anything for him, but he also knows that the birds are exhausted, the good bow is hidden, the cunning rabbit dies, and the dog cooks the truth, once he really does what he wants, once those guys really come, I am afraid that he will be the first to die.

"Forget it, let's take a step at a time, take it slowly, and I don't think I'm really going to be like myself. Lu Xiao thought to herself.

These guys didn't come directly, there must be something to stop them, and it took a lot of effort to get themselves over, Lu Xiao didn't believe that those guys could send things over endlessly.

Now that he has cultivated the soul core, Lu Xiao is introverted, carefully perceives, and tries to feel the souls of the creatures around him.

After a while, Lu Xiao withdrew from the state of perception full of disappointment, although these people in the city, although they could vaguely feel a mysterious fluctuation in their bodies, they could not feel it as clearly as they felt their souls just now.

Now, Lu Xiao can't even perceive his own soul in the soul core.

The original huge divine consciousness was all absorbed by the soul core, and at this moment, his sea of consciousness was empty, and there was not a single trace that could be used to nourish the soul core.

And the villagers and ancient monks of Ice Thorn Village had just suffered heavy losses, and they were all very weak, and the speed of absorbing spiritual energy had slowed down, and the feedback to themselves was even more negligible.

"I don't know how long it will take to recover. Lu Xiao was depressed.

Then, Lu Xiao spread out his divine sense and explored the location of the ice core forest again.

Now that his divine consciousness has all condensed into a soul core, there is not much he can use, and he must control another batch of beasts as soon as possible to recover a little.

It took an afternoon, with the help of the fifteen beasts that he had originally subdued, Lu Xiao controlled another twenty-one beasts, turning them all into dead corpses, completely under his own control.

Dozens of beasts of all kinds were entrenched in the Ice Imperial City, and the faint gray aura in their bodies emanated, which was quite imposing.

As the essence of heaven and earth continued to gather, Lu Xiao also got a hint of feedback, and in the dry sea of consciousness, a trace of divine consciousness finally appeared.

However, this speed was still too slow, and Lu Xiao turned his attention to the three ancient monk leaders.

These people have been around and practiced since ancient times, and there may be some special way to quickly absorb the aura.

Lu Xiao directly explored the sea of consciousness of the three people with his divine sense, and sure enough, he found a formation called: "Huiling Array".

By placing this array in the city, it can forcibly gather the aura of heaven and earth within a radius of tens of thousands of miles to help the people in the formation cultivate.

The arrangement method does not seem to be very difficult, with the unique formation flag of the ancient monks as a guide, and the formation can be formed by arranging the formation in a special way.

Discovering this, Lu Xiao immediately summoned all the ancient monks, and each ancient monk took out two broken small flags from the space in his body, almost every one of these flags was tattered, and many of them were missing a corner or a few holes, and it looked as if a gust of wind could blow it away.

However, above the small flag, there were slight fluctuations.

Lu Xiao probed the past with his divine sense, and found that the small flag could resist his own detection, and he couldn't see what was contained in it, this flag seemed to be the inheritance of these ancient monks, and when they found them, they didn't even have the most basic weapons, but these flags were kept by them until now.

"It's strange, this tattered little flag has this ability, and I must investigate it later. Lu Xiao pondered as he asked the three leaders to set up a formation in the city with five thousand ancient monks.

For a time, the city was full of ancient monks, and many ancient monks, under the guidance of the three leaders, planted the flags in their hands on the ground according to a special law, and as the flags continued to be planted, a mysterious pattern was outlined.

After all the ancient monks planted the flags in their hands, the three leaders walked to the middle of the formation in unison and inserted the scepter in their hands on the three formation eyes vacated in the center of the formation.

As soon as the formation was formed, Lu Xiao keenly felt that a strong wind formed by the convergence of spiritual energy was blowing from the surroundings and swept through the Ice King City.

This gust of wind not only did not make the people in the city feel uncomfortable, but everyone felt extremely comfortable, and the villagers of Ice Thorn, who were already weak, felt this wind and couldn't help but greedily absorb the aura in it, one by one, like fish in water, full of longing.

Immediately, around the royal city, countless tiny aura dragons condensed, and under the effect of the formation, they turned into a burst of aura light and scattered in the city.

The ancient monk was extremely sensitive to this aura, and involuntarily opened his mouth wide, greedily absorbing it.

The Ice Thorn villagers also sat down one after another, running their internal exercises, doing everything possible to absorb the abundant spiritual energy between heaven and earth.

The spiritual energy in the bodies of everyone in the city recovered at a speed visible to the naked eye, and Lu Xiao could gradually clearly feel that the spiritual power that was fed back from all directions was transformed into pure divine consciousness and absorbed by himself.

Almost all of the divine consciousness that entered the sea of consciousness was absorbed by the soul crystal in the center of the sea of knowledge, and the purple light of the original purple-black soul crystal became brighter and brighter.

Lu Xiao was extremely depressed in her heart, and she didn't know when this soul crystal would be absorbed into it.

However, at this moment, Lu Xiao's divine consciousness clearly felt an unusual fluctuation in the sea of old man's consciousness in an ice thorn village not far from him.

The fluctuation seemed to be connected to the mysterious space he had just perceived, and Lu Xiao vaguely felt a weak shadow in the center of his sea of knowledge through his sea of knowledge, exuding an aura that made him feel familiar.

"This breath...... It's a soul!" Lu Xiao was excited in his heart, and for the first time, he clearly felt the fluctuations of other people's souls.
