"Emily, keep scanning." M4 stood around the corner and gave orders through the headset.

The SPA guards the stairs, and the letter looks behind.

"Captain, there's a special magnetic field screen blocking my equipment."

"Put the plane map out, letter, come here." M4 looked at the letter that came with a small step and said, "This is the floor plan of the next floor, what do you think?" ”

Xin looked at this diagram and had a headache, the structure was too simple. There is a corridor in the middle, and there are six rooms on both sides, a bathroom, and two small warehouses.

"To be honest, we basically have nowhere to hide in such a structure, and as long as something finds us in any of these rooms, we have to fight hard. What did you do when you encountered this situation before? The letter frowned.

"Break head-on." M4 is like talking about something that is very mundane.

“…… Where's your scout car? Shin asked, looking at Tsui.

"What are you going to do?"

"Lend me one."

The letter took it and became proficient in the control.

"Well, it's about the same as the RC car I used to play with." Xin thought for a moment.

"Of course it's to explore the way." Xin controlled the car and smiled slightly.

Through the display screen, I saw that the lights on the next floor were very dim, and the car jumped up and pressed the light switch. The ceiling lights lit up in rows, allowing Shin and the others to see the situation in the corridor clearly.

"Yes, quite my style." Emerald smiled.

“……”

The letter steered the cart into the open door, and there was nothing special except for the bloodstained desk.

Shin wanted to move on, but there was a disturbance on the display.

"What's going on?" The letter asked Cui.

Cui spread his hands: "I also said just now, there is a magnetic field, and now it should be that the distance of the car is too far to cause the signal to be unreceivable." ”

"Prepare to go down." M4 said lightly.

"Let's go to the office and see if there's any important information."

M4 nodded towards the letter.

The four of them went downstairs cautiously, trying not to make a sound.

M4 gestured to the others, "I'm in first, you guys follow slowly." ”

Shinya only understood a rough idea, but he was stunned as he looked down the hallway.

M4 enters the room and gently opens the drawer of the desk, which contains some papers and a bunch of keys. After a brief look at the papers, I put them in my backpack and put the keys in my pocket. When I was about to leave, I found that there was one person missing from the room.

"Believe it." M4 opens its mouth gently.

"I'm at the door, don't come out yet." The sound of a letter came from the headphones, not enough but full of tension.

"What's the situation?" M4 and the others leaned against the wall.

"The scout vehicle is gone, and there are other people or things on this floor." With guns in both hands, Shin stared at the entrance and exit of the hallway today, and kept scanning the other doors for something unusual.

"Lee, what's going on outside?" The letter whispered.

After a while, Lee's response came.

"Not yet."

"M4, the three of you are ready to support me, I'll go explore the way."

With that, Xin stood up gently and walked forward slowly. When he reached the second door, his left hand slowly turned the doorknob, then opened a crack and slammed it open, but there was no sound.

Finding nothing out of the ordinary, he moved on.

At this time, Xin's forehead was covered with sweat, and his heart was also nervous.

M4 and the others are trying to listen to the sound in their headphones.

The letter came to the third door, just like it had just been. This time, though, when the door opened a small crack, a force opened the door and pulled the letter inside.

An incomplete call for help came from the "Help......" headset, and M4 and the others immediately took action.

At this point, Shin's headphones fell to the side, and a zombie crushed him underneath him.

This zombie has a lot of strength, its eyes are bloodshot, and there is still scrap of flesh on its teeth. The spear was pressed against its jaw, and then its thigh lifted to break free.

The sound of battle was also heard outside the door.

Shin pulled out his spur and charged at the mutant zombie. Even though it was a mutant, it couldn't resist the attack of strengthening people's letters, and was stabbed in the head and ended his life.

But there was no brain or blood coming out, and when Shin pried open its skull, it was covered with cobweb-like blood vessels, with a crystal in the center.

"It's okay." M4 came behind the letter.

"It's okay, come and see this, I've never seen a zombie like this in their heads. Have you seen it? ”

M4 shook his head.

"Emily, come on."

Cui, who was guarding the doorway, retreated into the room and took out a test tube to store the blood-colored crystal.

"Now that this floor is cleared, we'll see if there's any useful information. Work in pairs and stay safe. ”

This time the letter and Emerald group.

Came to a clean room, the room was very simple and there was a book on the table.

Turning the first page, this is a notebook.

"Royal Research Institute, Researcher 013."

Xin touched his chin: "I'm still a big official." ”

The notes are preceded by some of the experiments and daily routines. The second half is a little depressing.

"What is this?" Emerald watched Shin's face change.

The letter did not speak, but continued to be flipped through.

The second half of the note is mainly written about human experiments, and the royal family officials have requested that the virus in the biochemical area and the virus of zombies be subjected to human experiments. No. 013 was forced to execute, and the above process was also more detailed.

What Ling Xin cares about is a successful test piece, zero. Her presence made the rest of the lab and even the royal family ecstatic, but the point was still to come.

Various experiments have shown that Zero can manipulate some low-level mutant creatures, but the great thing about it is that she can also create mutated creatures on her own.

Perhaps 013 felt that the experiment had reached a point of no return. He created a matrix, a horde of monsters! So he wanted to destroy her.

However, on the surface of the aforementioned diary, Zero relies heavily on 013. But 013 wants to destroy her, which is really a dramatic script.

Now the tragic situation, it seems that No. 013 has failed. But who can be blamed, it's all self-inflicted!

"Hey! Soul back~" Cui kept waving in front of the letter.

"Oh! I'm embarrassed to get distracted. The letter responded.

"What are you looking at? So obsessed. ”

"I think you've got an account."

M4 and the two searched to no avail, and they met with the two of them.

"Well, this thing should be more important." The letter tosses the note to M4.

M4 opened it suspiciously, but the more he looked at it, the worse his face became.

"These bastards!"

Cui and SPA also went up to take a look, and the result was the same reaction.

"Shall we retreat now, then?" Lee's voice came from the headphones.

"Retreat? I'm sorry, but now that you know the secret, you have to stay here. ”

An unknown communication interjected.

"Someone from the royal family?" M4 said calmly.

"That's right. We are interested in the bodies of the redeemers. The man's voice grew playful.

M4 smiled, "You're not the first to say that. ”

"It won't be the last."

The two were not interested in the tense conversation letter, and at this time he had already put the headphones around his neck and went downstairs to investigate.

Lee also rushed over at this time, along with the letter.

"Cui, set up an independent channel and don't be monitored by them, can you do it?"

"Small, two minutes." Emerald then manipulated the small screen on her left arm, and then gestured "OK" to M4.

"Okay, now they're not going to hack into our channel."

"It's time to call for your reinforcements." The voice of the letter remembered.

"I try." M4 has a real headache when it comes to thinking of reinforcements.

"This building is not in danger, what to do next." Lee also asked.

Just as M4 was thinking, Tsui's instrument remembered the alarm!

"Missiles! Enemy attack! ”

The two of them at the bottom of the building were fine, and the three of M4 broke out of the window one after another.

"Boom!"

After a roar and a tremor of the house, Shin looked at the three people who had jumped from the third floor without any problems.

"Ahem! Is this all okay? Xin patted the dust off his body.

"We are in human form." Li next to him said lightly.

"Humanoid?"

"That's it...... Tactical robot bar"

“…… All right. ”

"When I get out, I can let you know about it." Li glanced at the letter wickedly.

The letter gave a cold war, resolutely not!

"Everyone's alright!" The M4 asks about other people in the headset.

"No problem!"

"There's a problem! A large group of royals is coming. They are well equipped. Cui looked at the information that the instrument gave back.

The lab has gradually become noisy, and now M4 and the others are surrounded.

"Stay, we still have a chance here, we can use those monsters and zombies to contain them, and wait for your support."

M4 felt that the letter was right: "Let's find a place to attack and defend, and also to facilitate the retreat." ”

"Then it can only be the innermost building, and I feel that building is dangerous." Cui looked at the monitor and said.

"Let's go." M4 took the lead, and Shin and others followed closely.

The five of them shuttled through the dense trees, and they only bypassed some aliens and zombies when they encountered them.

"Major General, we're here." A man with a mechanical prosthetic eye said to a disheveled teenager.

"Send someone in."

"Major General, I suggest a covering bombardment to completely destroy this area. Sending soldiers in hastily would have caused immeasurable losses. The man also wanted to persuade the teenager to change his mind.

"Old Tower, when is it your turn to order me?" The young man cocked Erlang's legs and said nonchalantly.

"It's the subordinates' who are wrong." The man lowered his head and stepped aside.

"Send three teams of people in, and kill people when they see them, but the corpses must be protected and not damaged." The boy smiled faintly, like a demon smiling there.

"Captain, they're coming."

At this moment, M4 and the others hid in the back of the roof, observing the royal soldiers who came in from a distance.

"How many people came?"

"There should be more than thirty people in the three teams." Cui roughly estimated.

"They're well-equipped, I'm afraid those aliens and zombies won't be able to stop them for long. Unless that's the so-called zero, we're going to have more people. Shin watched through the binoculars.

"Will you make a move?" SPA also looked at other places suspiciously.

At this moment, downstairs in the letter and others, a young girl was lying quietly on the operating table. And all around her, and even on other floors, were monsters guarding her.

Xin and the others don't know the situation in the building, but they just feel that the building is dangerous!

But it also proves that the most dangerous places are the safest places.
