As if some kind of switch in their bodies was pressed, all the zombies returned to their former violent appearance and began to launch fierce attacks on all the soldiers.

They used the shelters made of building materials and their numerical advantage to surround and encircle the soldiers.

The trained soldiers were no pushovers either. They gathered together, turned their backs to their teammates, and shot at the zombies attacking from all around them.

"What on earth is going on?"

The scene became chaotic, and Shen Yiyue, who had been observing, began to be confused about the situation.

These zombies themselves are strange enough. At first, they seem to be escorted here by these soldiers to accomplish something.

After they had already started working, they suddenly changed their attitude and began to attack the soldiers escorting them.

They were like the lower-class refugees who had planned to riot long ago; this kind of wisdom was totally unlike anything zombies could possess.

Soon, the zombies, whose number far exceeded that of the soldiers, had completely surrounded the soldiers, although many of them fell under the hail of bullets.

Having lost their distance advantage, all they could do now was panic.

"What the hell is going on?! What did the headquarters say?"

"We have to break out from one direction!!!"

It didn't take long for the zombies to overwhelm all the soldiers, and their flesh and blood were eaten up.

Ning Yu also noticed a detail. The communication devices on the soldiers were taken off by the zombies and crushed one by one.

"This doesn't look like zombies at all. It's more like a well-disciplined undead army."

Ning Yu talked to herself as she watched their coordinated movements.

The soldiers' equipment was also divided, and their helmets and bulletproof vests were shared and worn by some zombies who were close to them.

However, after doing these things, the zombies walked towards the pile of materials that had just been discarded on the ground, as if they had planned it in advance.

He started to reassemble the device on the mechanical base.

But unlike the previous installation method, they first removed some things on the base, and then began to set it up in a different way.

About half an hour later, the square altar-like object was built, with a sunken groove in the center.

Something began to gather and flow into the groove, causing a faint white light to slowly emanate from it.

A zombie wearing a soldier's helmet came forward and took out an octahedron-like object from a backpack.

The thing was transparent all over, and as if it was attracted by some invisible force, it slowly floated out from the zombie's hand as soon as it was taken out, and flew straight to the center of the altar groove.

The white light gathered in the groove suddenly seemed to have a target and converged towards the octahedron, charging it to emit dazzling light.

Many pathways suddenly lit up from the ground, like interconnected circuits, slowly illuminating the entire space brighter.

"Buzz buzz buzz"

The [Long-distance Disposable Communication Device] in Ning Yu's pocket suddenly began to vibrate.

This is a signal from Ning Xuan that she has contacted him.

Ning Yu immediately stopped watching what the zombies below were doing. She and Shen Yiyue slowly stepped back a few steps, then took out the [Long-distance Disposable Communication Device].

"Sister, are you all right?"

Ning Yu took out the earphones again and inserted them into the [Long-distance Disposable Communication Device]. Then Ning Xuan's voice came from the earphones.

"We're fine, any progress over there?"

Ning Yu gave one of the headphones to Shen Yiyue, and then replied in a very low voice.

"There is someone who is willing to help us, and she gave me very important information."

Ning Xuan's voice came again from the other end of the headset.

"Who is it?"

Ning Yu also wanted to know where Ning Xuan's power borrowed from within came from.

"It's Lacey."

Ning Xuan said a name that Ning Yu was very familiar with.

"It's her? How is it possible?"

Ning Yu recalled the rainy night in Tianshen Elementary School when the blue-haired mechanical girl used her giant sword to cut her knife in half.

Why would such a guy help me? "She didn't say why. I guess maybe she had some conflict with Chenxing."

Ning Xuan briefly recounted her encounter with Lacey in the lower level of Eden. Ning Yu frowned after listening.

"Okay, let's talk about the information about Morning Star first."

Ning Yu knew that she shouldn't focus on this point now. As long as Lacey's goal was inconsistent with Chenxing's, she could be used.

No matter what her purpose is, she must first resolve the deadlock set by Morning Star.

"The man who wants to capture my sister alive is called Leon."

Leon? Is this the name of 'that man' that has appeared countless times?

Ning Yu felt a little unfamiliar with this name, because she had never heard this name in the information that Lin Hao had obtained from the virus. She thought it would be "William".

"He is currently busy with the critical phase of the underground works for the so-called final rites and cannot be freed."

Underground engineering?

Ning Yu and Shen Yiyue looked at each other. They were right below City A at the moment and had encountered a large group of strange "zombies".

"This is also the reason why Chenxing dared to come and kill my sister at this time."

"She has been using her ability to control zombies to do some tricks under that adult's nose. I'm afraid it's all for this moment."

After listening to this, Ning Yu still felt confused.

"Then why did she want to kill me?"

"I asked this question as well. Lacey said that there are similar projects under the ground in City A, and my sister can go underground through these buildings."

Ning Xuan sent a string of building addresses, but what she didn't know was that Ning Yu and the others were already there.

"As for the reason, she said that once my sister gets underground and goes to this coordinate, she will know everything."

Ning Xuan sent another string of coordinate addresses.

"If my sister sees that kind of mechanical building on the way forward, it looks like an altar."

She continued to speak, but before she could finish, she was interrupted by Ning Yu.

"Is there a luminous octahedron in the middle, and will black flames emerge after a period of time?"

When Ning Yu heard the word "building", she quietly walked back to the front where she could observe the area below.

The octahedron was spinning faster and faster, but it seemed to be contaminated by something, and black flames began to emanate from the groove in the middle.

The flame overflowed from the groove like liquid and then flowed out slowly.
