After completing the test of the power armor, he also built a simplified version of the armor for Yeyuechi and Xiaoqing, which is not all about saving the best materials, but mainly because their soul will strength is not enough to control the ultimate version of the power armor.

Of course, if the two of them are willing to implant the kind of microchip that adds the induction array under the scalp, they can also control the ultimate version of the power armor.

It's just that when the two girls heard that they needed to shave their heads implanted with microchips, their faces suddenly changed greatly, and it seemed that it was even more unacceptable for them to shave their heads, so in the end, they could only build a low-profile version of power armor.

However, even if it is a low-profile version, the combat effectiveness is also quite impressive, and in general, after being equipped with power armor, one can easily beat dozens of themselves who are not equipped with armor.

Most of the things that should be prepared have been prepared, although I dare not say that I am 100% sure of dealing with the old demon of the Black Mountain, but with the current situation of armament, no matter how you look at it, you will not lose.

However, occasionally I will receive a message for help from the imperial court, saying that I have found a very powerful monster, and then take the little Qingyue Pond to run all the way to subdue the demon and eliminate the demon.

However, most of them are some unjustly killed lonely souls, and Zhou Bufan has also done a few times to wrap up Qingtian, according to the information provided by those resentful souls who died unjustly, and found out a lot of corrupt officials and corrupt officials who are unjustly killed.

It's just that there is really a big problem with the soul reincarnation mechanism in this world, and there is no real underworld agency to manage it, so I can't bear to watch those resentful spirits get what they want, and after the resentment in my heart dissipates, I end up in a state of desolation.

Therefore, after obtaining the consent of those resentful spirits, they were all included in the formation space of the Soul Eater Array, so that they could embark on the path of ghost cultivation, which could be regarded as further increasing the power of the Soul Eater Array inadvertently.

The Soul Eater Array was originally an incomparably evil thing, but in the hands of Zhou Bufan, it evolved into an existence that was somewhat similar to the Western Elysium.

It is said that the normal method of soul devouring array sacrifice refining is actually to forcibly refine those souls with powerful mana, and with the help of the souls of those who have died unjustly, with the mechanism of resentment, they are transformed into soul eaters.

This would be very efficient, and in principle, a simple and quiet takeout of a town would soon be able to measure thousands of Soul Eaters.

Moreover, those soul eaters were forcibly sacrificed to their souls in front of them, and the resentment in their hearts was extremely great, so once released, they would devour all the living beings they encountered, and the power was extremely terrifying.

However, Zhou Bufan has taken a completely different path, and this kind of cooperation to introduce a lot of resentful spirits will indeed be very inefficient.

Moreover, those resentful spirits were almost exhausted because of the resentment in their hearts, so this famous Soul Devouring Array had lost the ferocious aura it should have, so its damage would be reduced a lot.

However, this method also has a great advantage, because all the spirits in the Soul Devouring Array have not lost their intelligence, so they can self-cultivate to improve their combat effectiveness, so the development potential will be greater.

Another and most important point is that it has recently been discovered that spirits can actually produce faith power, and Bi Xiaolan has successfully lit up the light of faith in the sea of knowledge, and the benefits are indeed extraordinary.

Sometimes I really suspect that the legendary Western Elysium is a similar formation space, and the purpose is to absorb the faith power of those devout believers.

The days passed day by day in this busyness, and I didn't know that it was already the beginning of April in the layout, and it was more than three months before the date of the weakening of the spatial barrier of the underworld.

All the preparations have been prepared, and the Qi training has successfully reached the fourth layer of Qi training that has been missed for a long time, and it can finally further purify some of the materials at the bottom.

Although everything is in place, there is still a lot of work to be done every day:

Analyze the possibility of using the induction array to build the spatiotemporal communication positioning device;

Analyze and study the space where the Soul Devouring Array formed the formation, and what kind of latitude space it belongs to;

Analyze the possibility of using the belief crystal particles to construct a consciousness teleportation array that transcends time and space......

There are many mysteries and endless knowledge, waiting to be explored and discovered, of course, you have to find time to exercise the Qi field to strengthen the soul consciousness, and of course, there will be an occasional mission to slay demons and eliminate demons, so time is never enough.

——

There were a few rooster crows in the distance, and it was another Zhou Bufan who hadn't slept all night, and finally put down a few small devices that looked a little similar to Bluetooth headphones.

This thing is a communication device created with the help of the overlapping induction array, and its function is somewhat similar to that of a walkie-talkie, which can be said to be the most basic communication device.

Of course, this thing is different from the walkie-talkie, this kind of induction array communication device theoretically has no distance limit, maybe even if you go to the netherworld of another dimension, you can still communicate with this human world, as for the actual situation, you have to try it to know.

Sure enough, after a while, Xiaoqing, who got up early, entered the laboratory with hot water and a towel.

"Childe, don't stay up late to cook things in the future, it's not good for your health." There were no outsiders present, and Xiaoqing spoke a lot more casually.

"There's no way, the mental state during the day is not as good as the state late at night."

"This is gradually corrected through habit formation, just like the concubine body, which used to rest during the day and move at night, but now it has been corrected."

"Well, let's talk about it later, bring this thing and try it first." As he spoke, he picked up a small device on the table and put it on the other party's ear, which was indeed very moving.

Although the earrings given by Childe looked a little ugly, they were given by Childe, and he even wore them himself, so he closed his eyes slightly and raised his head, waiting for Childe to provoke and be light.

"Xiaoqing, you wait here, I'll go out and try the new device to see if it works!" As he spoke, he threw out the flying sword, jumped directly on, and quickly flew out of the window.

This situation made Xiaoqing a little unable to react, why did he fly away with a good look, was he angry? But he didn't do anything, why should Childe be angry?

Although her mind was full of doubts, Zhou Bufan asked her to wait when she left, so she could only continue to stand there and wait.

"Can Xiaoqing hear me?"

"Childe, what did the concubine do wrong, please make it ......clear to the childe" Hearing Zhou Bufan's voice from his ears, he quickly turned around and bowed down, but he didn't see anyone.

"What did you do wrong, just ask you to help experiment with the communication device, it seems that things are very good, and the call is very clear."

“…… Childe actually learned his heart? I asked very suspiciously.

"What's his heart, it's just a kind of induction array based on the use of the array, don't you notice that the sound is coming from that little thing?"

"His psychic weapon?"

“…… Well, you think that's it. ”

After muttering and chatting for a while, he returned to the laboratory with the flying sword, although the distance of the test just now was only thirty-four kilometers, but it was basically certain that in this human world, this kind of communication was difficult to interfere with.

Because there are many formations around the laboratory, they have not been able to interfere with communications.

"Childe is really a person who has never been seen before or since, and he can actually create his heart magic weapon."

"Don't make a fuss, in the world I came from, everyone has this kind of thing, not only for phone calls, but also for face-to-face video chats."

“…… The world where the gods live is really not comparable to the mortal world. ”

"I don't know if there is a fairy world in this world, but the world I came to is definitely not the fairy world you said."
