If the city is destroyed, it can be rebuilt, or just some important facilities, such as air defense systems, can be built first.

It doesn't matter if there are air defense facilities or not, as long as the ghost soldiers can reach the land, there is basically no danger, and they can use the dirt as a cover to make the impact spear completely useless.

The establishment of air defense facilities is a declaration of territorial possession, and if there are inter-factional fighters, they can be used to retaliate symbolically against those fighters.

What Mu Yi cares about is the geographical location of Nahai City, which is closest to the Gate of Time and Space, so that it is convenient to carry out the next move against the cross-forces.

After explaining the arrangements of the sea city to the overlord, he returned to the question at hand, about the structure of the mist array.

The Mist Demon can use its own elements to transform the fog, but the fog applied to a certain place has a time limit, and if you want the fog to exist for a long time, you have to maintain it constantly, and the fog demon itself cannot stay here forever, so it needs a formation that can operate autonomously to generate uninterrupted fog.

The array diagram is to use tools that can convert the fog element into fog, and arrange those tools in the area where the fog needs to be arranged.

The essence of the elements has not yet been analyzed by scientific theories, so Mu Yi has no way to make those tools, so he uses a compromise method, half technology and half ghost.

Find a thriving locust tree, hollow out the trunk, add human bones to it, and then let the puppet-level ghost inhabit and merge with the locust tree, and then the ghost will transform the elements in the air, conjuring up two types of mist: water mist and elemental mist.

After the locust tree is renovated, it is transplanted around the city of Zhezhong, and the ghosts in it can be replaced in turn, which is equivalent to the patrol of soldiers.

In terms of arrangement, it is easy to say that the 400,000 troops of Green Firefly are here to be dispatched, and what needs to be bothered is how to arrange them.

Mu Yi's heart couldn't sink anymore after hearing the report from the Gate of Time and Space, and he couldn't concentrate on the design on the fog array. Simply let the fog demon arrange it himself, and said, "You try to come first, don't worry, if there is anything inappropriate, then slowly adjust." ”

The mist demon with a gray virtual body said respectfully, "Yes, Hades Lord. ”

Mu Yi rubbed his eyebrow bones and said tiredly, "Okay." Inform me of anything, and I'll go back to Zhezhong to see. ”

"Yes."

The Fog Demon did not dare to slack off, and devoted himself to the design of the Misty Array Diagram, intending to add additional effects to Mu Yi's requirements to form a Ecstasy Array and strengthen his defense against Zhezhong.

At this time, it was already more than two o'clock in the middle of the night, and the battle on the side of the Gate of Time and Space had lasted for half a night, and the situation was becoming more and more unfavorable to the Tiance Alliance.

The attack ships continue to launch nuclear attacks on the city, as if to wipe it off the map. Of course, they won't blow a hole in the earth yet, just turn the buildings there into dust.

So far, everything is still in Mu Yi's expectations, what makes her uneasy is time, and many plans have to be delayed after the cross-time and space forces.

As time goes on, Mu Yi's method of restricting the Heavenly Dao Cultivators will weaken.

Mu Yi thought that he could only take one step at a time, and when he returned to the repair shop, he saw that Mi Xue was still keeping vigil, and said with a smile: "Sister Mi Xue, you are not sleepy?" ”

Michelle turns off the movie she's watching on mute. He got up and pointed to the door, and when he walked to the door, he said, "It's okay." There are so many blank paper samurai outside, it would be bad if something happened. ”

"Ann, with Ben Shaoxia here, it will be fine."

Michelle pursed her lips, shook her head in distrust, and said, "Say it again." Didn't Brother Xu just be slashed a few times by the samurai when he was sleeping last time? ”

"Ahem."

Mu Yi coughed dryly twice, turned his head sideways and thought, "Yes, Sister Michelle, did you see it?" ”

"Okay, let's not talk about that, what's the bad thing about going outside for so long?"

"A weak woman. What bad things can I do. Mu Yi saw that Mi Xue didn't deliberately want to know what he was going to do, just to find a topic for chatting, so he said nonsense: "If it's true, you have to help me keep it secret." ”

Michelle raised her hand and swore, saying, "Don't worry, don't you know my secret too." ”

Mu Yi said solemnly: "Actually, I'm looking for a way to destroy the world." ”

Michelle also said solemnly: "I believe it." ”

The two of them smiled in unison, as if they had a common occupational disease, and they understood that the words were somewhat real and somewhat fictitious.

Mu Yi looked at the time on his watch and said, "When Wang Yi and the others wake up, I don't know when they will wait, it seems that I have to help them." ”

"How can I help, didn't they condense the spirit core in their dreams?"

"Let's go, Sister Michelle, just take a look."

Mu Yi took Mi Xue back to the resting place where Wang Yi and the others were resting, and took out a black storage bag from a car next to him.

It contained a ghost spirit bead, and Mu Yi explained to Michelle that the ghost spirit bead could increase the concentration of elements in the surrounding air, and placing the ghost spirit bead next to Wang Yi would increase the elemental activity in their bodies and help the condensation of the spirit core.

Mi Xue saw Mu Yi wave a blue light curtain on Wang Yi's face, and broke Wang Yi's mouth open, as if to put the ghost spirit bead into Wang Yi's mouth, and asked, "Xiaoying, can you eat this ghost spirit bead?" ”

"Theoretically, it can't eat dead people, it's non-toxic and harmless, it's a pure form of energy."

Michelle picked up a ghost spirit bead, felt its hardness, and asked, "Can this thing be digested?"

Mu Yi vetoed, "No, it will be consumed as you use the ability." ”

"Does that mean this thing stays in the stomach for a long time and doesn't hurt in the stomach, or"

"I didn't expect it, so forget it."

Mu Yi had never used the Ghost Spirit Bead to strengthen his elemental power, so he wasn't too good at using this thing.

The Ghost Spirit Bead was placed directly on Wang Yi's body, and some parts were placed in each part, so that the elements emitted by the Ghost Spirit Bead could wrap them.

Mu Yi quickly finished placing the ghost spirit beads and said, "The rest can only rely on themselves. ”

"It's not been 12 hours now, and I remember Xiaoying that you said that those potions would make them sleep for two days."

"Yes."

Mi Xue deduced: "In other words, they still have one and a half days, and they should be able to successfully condense the spirit core." ”

Mu Yi sighed slightly and said, "This can't be determined. Whether it is a ghost spirit bead or a potion, it only plays an auxiliary role, and the use of elements is partly idealistic, and it is difficult for the outside world to interfere in that aspect. ”

Michelle saw that she seemed to know a lot about the elements, and asked, "Xiaoying, what do you think the elements belong to?" ”

"Except for the Heavenly Dao Cultivators, no one should be able to answer, I have studied the elements, until now, as far as I understand at the moment, half of the elements belong to science and technology and half belong to metaphysics, and metaphysics is a kind of technology that is so complex that it can only be expressed by vague concepts, and it basically belongs to science and technology in summary, but we have not yet reached that level of understanding."
