In line with his understanding of the undead, Zhang Qifan made a lot of targeted arrangements to ensure that there would be no species such as undead black warriors who were good at stealth.

At the same time, he also picked up a large piece of soil from some meteorites.

A handful of sip soil was placed on the real platform, and Antonio crouched on it to observe it carefully, sniffing from time to time, and seemed to like the smell of the stinging soil.

"What does it smell like? Why does it smell so good? Antonio asked curiously.

"The breath of the soul." Zhang Qifan said.

The breath of the soul? Antonio pondered the meaning of these words as he turned on the various detectors.

After a short moment, Antonio exclaimed in surprise: "This thing has a strong reaction to ultraviolet rays. ”

I saw that under the ultraviolet rays, the black soil was like slime, and the black on the surface was slowly receding, revealing the original color of the soil. The soil was detached from the meteorite itself, and its original color was grayish-white.

When the black color of the soil fades, the fine grains that originally resembled sand and gravel turn into powder with a gentle rub of your fingers.

I don't know if it's because the black layer erodes the sand into powder, or if it polymerizes the powder into sand and gravel.

Antonio's spirits lifted, it would be good to have a reaction, and if there was a reaction, he could infer a lot of things from these reactions.

"What does this thing do? What do you want me to do from this? Antonio asked.

Zhang Qifan solemnly collected so much soil and handed it over to him. Surely you know what these are doing.

Antonio needs a research direction, otherwise it is easy to study something that is inconsistent with what Zhang Qifan needs. That's a waste of energy.

Zhang Qifan said: "The breath of death can be absorbed by the undead, and there is it in the soil, so you can try to figure out its composition and whether it can be synthesized." ”

Zhang Qifan didn't need soul energy now, he already had a headache just by recovering his strength. But Antonio, Ferrol and others need it. Their souls are still weak.

There are many ways to enhance the soul, and Sleep and Devour are two of the most common uses by undead creatures. But it takes a long time to sleep, and it takes a lot of souls to devour. Zhang Qifan doesn't have these two things.

If the death energy in the earth could be extracted and absorbed by a method similar to devouring, it would not take a long time and a large number of souls.

After listening to Zhang Qifan's words. Antonio blinked. A look of excitement and excitement suddenly appeared on his face: "Good idea." Are you saying that we can also elevate our souls and then do the same perverted actions as you? ”

Zhang Qifan nodded, the soul is the foundation of an undead creature, and if he wants to achieve his strength, the strength of the soul is a must.

"Okay, leave it to me, look at me." Antonio instantly ignited 120,000 points of enthusiasm, and the fighting spirit roared.

……

The research task was explained. Zhang Qifan drove his strength, and Schneider drove Houyi. The two plus armor one after the other, led by the streamer, quickly walked through the floating wreckage.

Hou Yi's body was larger than before, and there was a silvery-white luster circulating on the surface, which was moist and moist. From that silver-white shell, Luo Xiu's excited 'Xiu's mental fluctuations' continued to be heard.

Having absorbed a large amount of liquid metal, Luo Xiu is no longer a metal villain, but a behemoth, larger than a god-level armor more than twenty meters high.

Because of the strength of the liquid metal, and because Luo Xiu's soul is too weak. The huge Luo Xiu is now difficult to move alone, it squats on the ground, and can simulate the power god vividly, but as soon as it stands up, it has to fall apart.

Hou Yi did not have an energy shield, so he could not resist the soul attack of the undead, and the soul of Schneider who drove Hou Yi was very weak, and he could not withstand even a soul impact of a streamer with a strength of only eight hundred points.

In this way, it is just the waste that can be used to let Luo Xiu cover Hou Yi's body and help it resist the impact of the soul. Luo Xiu also croaked excitedly because of the rare opportunity to let off steam.

The place they were heading to at the moment was the territory of another nearby lord.

According to Streamer's memory, this lord was an undead spirit, much longer than when Streamer was in existence, having left the territory and traveled a lot.

Naturally, there is also more knowledge about the world.

As soon as he entered the territory of the undead lord, Zhang Qifan keenly felt some gaze coming from the floating pile of wreckage.

Looking up, from time to time, one or two skeletons and corpse witches poked their heads out of the pile of wreckage, observing Zhang Qifan and his party. Their eyes were more focused on the two armors of Lishen and Houyi, and they only swept the streamer and didn't pay much attention to it.

This territory and the streamer territory are simply two completely different worlds. The territory of the streamer is an undefended world, but it is like a heavily guarded fortress.

In the territory of the streamer, except for the bone horse, the rest of the undead creatures would be free. In other words, they have no soul connection with the streamer at all.

I don't know if it's because the streamer was born for too short a time and doesn't know how to establish his own rule, or because it's his nature to disdain to rule over other undead creatures.

But this territory is completely different, in Zhang Qifan's eyes, this territory is the norm for undead creatures, all the undead creatures in the territory are the lord's people, and the lord will grasp it as soon as there is any trouble.

The voice of the streamer sounded in Zhang Qifan's heart: "Darad is a terrible undead, he killed all the free souls in his territory, and then replaced them with his separated soul fire, all the creatures here are his slaves." ”

"Kill?" Zhang Qifan asked: "Why do you want to kill, can't you swear with your soul?" ”

Killing the undead, devouring the souls of the other party, and then using this soul energy to recreate the soul fire is certainly one method, but it is extremely wasteful. The devouring process is wasteful, and the newly created soul fire also requires a lot of energy and time to grow.

And this method has a bigger flaw, even if it is a very mature undead creature like a streamer, after killing, it can only harvest energy, and its own memory and knowledge are all cleared.

With this method, even if the undead in the entire territory are converted into their own subordinates, they will only get a batch of the weakest undead, and they still need to be cultivated from scratch.

How can the soul oath be convenient, and directly turn a mature undead creature into his own people.

Streamer hesitated for a moment, and then hesitated for a long time before he said, "Master, I have never heard anything about the soul oath from others. (To be continued......)
