"What now? Is it still in the past? Emerald asked, looking at the crowd.

"Let's go, I feel bad here." Shin rubbed his temples.

"Well, get out of here." The same goes for the M4.

The corridor is very long, almost seventy meters in shape. The letter and the others moved gently. The cell along the hallway began to empty, but the further forward it went, the more messy it was.

As we approached the exit, there was a lot of blood in the cell. It didn't seem to be a long time, and Shin and M4 looked at each other. They all saw a hint of surprise in each other's eyes.

This biochemical zone has existed for decades, and it is unlikely that there will be fresh blood. Unless, as the letter assumes, it's not as simple as it seems.

At the beginning of the letter, the people who judged the male attackers, especially the patriarch and Harvey, as the oldest and most experienced duo, must know something.

But he couldn't ask anything from Ke Lan's mouth. Now with Cui's failure, he and the others seem to have fallen into a blind spot. No support, no intelligence, no supplies.

"Ugh." Shin felt a headache and was comforted by M4 patting him on the shoulder.

"Don't sigh, I have a headache too." M4 rubbed his brow.

"What did you do when you were in this situation before?" The letter was a little curious.

"Improvise, what about you."

"Desperately struggling."

"Okay, okay, when is it, still chattering there." Ye made a dissatisfied voice, it was said that she had also come out of Moon Bay, and she didn't seem to be of much use yet.

"Don't look at me like that, am I depressed or do you want me to vent?" Ye looked at the letter with a smile, and murderous intent appeared in his eyes.

Don't overdo it, don't believe that Ye will do it.

"Wait." Hotaru suddenly stopped the group from moving on, pointed to a cell and said, "There are words at the foot of the wall. ”

"Go in and have a look." Shin pulled out his gadgets and tried to pick the door lock.

"It's useless, you still need a magnetic card to open the door." Emerald said with a glance at the door lock.

Shin retracted his gear, drew his sword, and made a cut. The falling steel plate is caught by M4 and Hotaru.

"You're outside, I'll go in and have a look." After the letter was finished, he went in, and Ke Lan also followed him in.

"It's coming to me soon! I'm done! A sentence was crookedly carved into the wall.

"Is it to be taken and executed?" Ke Lan Xuexin touched his chin.

"I saw like I was going to do some experiment." The letter shook his head.

"Faith!" Hotaru exclaimed.

Shin felt his feet empty, and his hand reflexively gripped the ground. And Ke Lan was not so lucky, dropping four or five meters and inserting his sword into the wall and hanging there.

And the door of the secret passage also began to close, if Xin didn't let go, it was estimated that his fingers would be pinched off, just when Xin wanted to change his left hand to support for a while, he thought of Ke Lan below, and gave up.

Hotaru wanted to come over and help, but it was too late.

"Stay in touch!"

After saying this, he let go of his hand, and at the same time drew his knife and plunged it into the wall.

"Damn." Of course, Hotaru had heard the letter and knew that he hadn't fallen yet. But at this moment there was the sound of the door opening from the depths of the prison, and heavy footsteps pierced it.

Now you know what this cell is for, Monarch Habitat! The former prisoners are estimated to have become monarchs.

"Hotaru! It's time for us to withdraw, believe in the faith. M4 and Ye Heli opened the door.

Hotaru glanced at the location of the secret passage, gritted her teeth, and followed M4. After all four of them go out, Hotaru and M4 close the door again.

"Cui, find a way."

"Understood."

"Letter, can you hear me?"

"I'm here."

"Cui will send you the structure diagram, and then it's up to you."

"Don't worry, stay connected."

"Hmm."

M4 chose a passage with experience, and the prison door behind him was constantly banging, and soon it would be impossible to hold on.

"How are you?" Xin looked at Ke Lan below and asked.

"It's fine!" Ke Lan's spear was stuck, and he was a little uncomfortable.

"I'll come in a minute, keep quiet for now." The letter heard movement outside, the sound of heavy footsteps.

The letter wasn't very worried, because he didn't think they would find him. Just as Shin was thinking this, footsteps were heard above him.

It can't be such a coincidence, right?

Xin slowly pulled out his sword, and came to Ke Lan's side with his hands and feet against the wall, helping her release the spear.

In fact, I wanted to go from above, but I didn't want to go down to the depths of the dark tunnel. But there's a boss waiting overhead. No way, let's bite the bullet.

The letter refers to the bottom, and the letter refers to the downward.

But the only thing that Xin cared about was that Ke Lan's gun was pointed at his crotch, which was really a little embarrassing.

"Hey...... Let's stretch the distance a little longer. Ke Lan smiled at the letter.

The two of them moved slowly downward, but the little girl ran out of patience.

"Ahhhh

"Patience starts with the baby." The letter said casually.

"Huh?" Ke Lan was a little dissatisfied, and sent the gun head up.

Fortunately, Xin braked in time and saw Ke Lan who was grimacing at himself, this little kid wants to teach a good lesson.

The situation on M4's side is a little urgent, and the two monarchs behind are following closely, and the door in front is still sealed.

"Captain, hold on, I'll open the door." This door is the only way out, and Emerald has to fight.

And the monarch also stopped at this time, the size of this space does not allow the monarch to act side by side.

The monarch in the back pushed the front one aside and stepped forward himself, looking like it couldn't wait.

M4 and Hotaru drew their short knives, and Ye Shou stayed beside Cui. didn't wait for the other party to attack, he and others took the lead.

Due to the limited space, the monarch can't move well, so it also makes M4 and Hotaru a lot easier.

Soon, the monarch fell to his knees, scars all over his body. M4 and Hotaru wanted to take the opportunity to end it, but the monarch behind them who was watching the show suddenly made a move.

One pulled the injured monarch back, then kicked it straight out. Hotaru took a quick step back, the soles of her shoes brushing her hair.

M4 stabbed it in the leg and pulled it hard, cutting off the muscles and nearly cutting off the entire leg.

The monarch staggered a few steps, still on his knees, losing strength in his legs and unsteady on his feet.

"Hold on a little longer! Right now! Cui was even a lot more rigorous in breaking the door at this time.

"Click—click."

"It's on! Evacuate. Ye was the first to enter to observe the situation, and Cui followed closely.

Hotaru and M4 also stepped back one after another, but still left some gifts. The moment the door closed, two shock grenades were dropped in front of the monarch.

Don't care about what's going on outside, look inside carefully.

It looked like a small shelter, and it was a mess inside.

"Look!" Emerald pointed to a place overhead, where there was a hatch and ladder.

"Don't rush, confirm the situation."

"Understood."

"Letter, please answer when you receive it."

"I'm ......"

The wheezing of the letter came from the headset.

"Where are you now?"

"It's still in that dark passage, it's too long here. Help me see how long it will be before I get to the ground. ”

“…… That's a thousand meters long! Faith, there are still 400 meters to land, and I can't detect it anymore below, there is a fatal problem, the oxygen is thin below. Emerald was a little worried.

"Understood."

"The headset has an oxygen supply function, but it's only thirty minutes, and you have to find oxygen underneath." Cui added.

"We arrived at a shelter and were surveying the surroundings. I will be in touch and good luck. ”

After ending the call, Xin looked at Ke Lan and said, "How are you, are you okay?" ”

"It's okay......" Ke Lan's gasp was heavier than the letter.

Shin adjusted the function of the headset, and an energy shield covered Shin's face. The letter took a hard breath, then took it off and threw it to Ke Lan.

"Save some oxygen for the first 30 minutes inside. Take a breath and turn it off. When you feel like you can't do it, suck it again. ”

"What are you going to do?"

"I'm okay, if you can't, you can give it to me again."

"Understood."

"Speed up."

After about three minutes, Ke Lan and Xin both landed smoothly. Shin took the flashlight off the gun, and the reason why he didn't use the gun was because there was biogas underneath.

It seems to be a construction area, but it must have been suspended now. Strangely, what exactly is such a deep place to do? And why does that prison have a secret passage to death?

After thinking about the secret passage and that message, I felt that it was a trap that was deliberately set up by someone later.

There are so many mysteries that I believe that the most important character at the moment is to find oxygen.

Ke Lan touched the letter and said, "There is a gate over there." ”

Xin looked in the direction that Ke Lan pointed, there was really a wooden door.

"Squeak-"

As a layer of ash fell, the wooden door was opened. Shin and Ke Lan stuck out their heads to look, and the yellow indicator light above their heads was still on.

Also, there are a few doors that don't seem to have much dust.

Someone's there!

Shin and Ke Lan slowly retreated to the room just now, but fortunately, the sound of the door opening just now did not alarm those "people." ”

"Give me the headset......"

Shin took the headset and took a breath of oxygen, then contacted M4.

"Letter, I heard it, and the letter is a little bad, long story short."

"I've found human traces underneath, and I'm ready to grab oxygen."

Immediately after that, the two lost contact, and only the "rustle" signal was heard in the headset.

"The letter and we have lost contact. They encountered traces of similar people below, and were ready to grab oxygen. M4 said, looking at the crowd.

Ye didn't say a word at this time, she was as irritable as everyone else. Hotaru appears to be a little calmer, and she hasn't spent much time with Shin, but she trusts Shin's abilities.

"Let's think about ourselves first, and believe that faith is okay." Hotaru simply comforted everyone.

"Little sister, it's up to us to do the next." Xin gave the headset to Ke Lan and smiled.

……

At this time, the three of them also fled to a shelter, but it looked neater, with a passage to the underground.

"Now in the direction of the place you said." Oga was becoming more and more unable to see through Boi's thoughts at this time.

I feel the need to ask the whole thing clearly.
