"You don't have to be afraid. Pen, fun, pavilion www. biquge。 info" Xiao Bing's expression was calm: "In the face of danger, the vast majority of ordinary people will make instinctive actions to survive, which is nothing to condemn, selfishness is not a crime." After all, only a very small part of those who can really sacrifice themselves for others. ”

"You, you don't blame me?" Wu Dongdong stammered.

"What's so weird." Xiao Bing said with a smile: "Such a small oxygen tank can be used by a person for dozens of minutes, it is not bad, and it does not play a decisive role." You want to be alone, it's just an instinctive sense of survival. ”

Wu Dongdong felt that Xiao Bing really didn't seem to be hostile, and he was much bolder, looked around, and asked, "Why is it so dark here?" Isn't it yet on the ground? ”

"It's seven or eight meters above the water." Xiao Bing looked at the blocking of the doors and windows on the side: "It won't last long, and it is estimated that water will come in after a while." ”

Wu Dongdong glanced at the grenade in Xiao Bing's hand: "You want to use this to blow up the hut?" ”

Xiao Bing nodded: "Actually, it doesn't make sense for you to come up with me." He threw a grenade and jumped into the well to avoid the explosion. When the time comes, we will be in more danger than in a safe house. ”

"You, why didn't you say it earlier?" Wu Dongdong's eyes widened.

"I don't have that time." Xiao Bing shrugged: "But you don't have to worry, since I have promised your teacher, I will definitely save you." ”

Wu Dongdong was silent for a moment, then raised his head and said, "You also said just now that selfishness is not a sin, right?" ”

"What do you want to say?" Xiao Bing asked.

Wu Dongdong said: "Seven or eight meters above the water surface, the water pressure is not very large. Just make a small opening to fill the place with water, and then break down the blocked doors and windows, and we can reach the surface of the water safely. ”

"You know a lot." Xiao Bing smiled and repeated what he had said before.

"These are just simple physics knowledge, as long as you use your brain, every junior high school student can think of it." Wu Dongdong glanced at the wellhead, and then looked at the grenade in Xiao Bing's hand: "But there is space under the ventilation shaft, and after the water rushes in, it will form a whirlpool and roll us in." So I recommend ......"

"So, you want to seal the wellhead." Xiao Bing picked up the grenade and shook it: "Use this?" ”

"That's right! I'm selfish, but as you said, there's nothing wrong with thinking about yourself. Wu Dongdong's heart was horizontal, and he said directly:

"Besides, your plan is inherently risky. Even if it turns out exactly as you envisioned, the water below will not flow into the tunnel slowly, but will pour in like crazy. From such a low place, they will be pushed out of the water very quickly. Even if they don't die directly, the drastic change in air pressure will leave them devastated. ”

"You insist on coming up with me, I'm afraid you have also taken this into account." Xiao Bing nodded: "But, if I say that I can save them, even if their lungs are squeezed by air pressure, I won't let them die?" ”

"You're just imagining." Wu Dongdong became excited: "And even if they can live, have you ever thought about the two of us?" Throw a grenade here, even if you hide in a well, it will be very dangerous! ”

Xiao Bing sighed: "You are really smart, and you are not wrong in what you think." If I were in your position, I would never think so comprehensively. ”

"Do you agree, then?" Wu Dongdong became short of breath: "I know that you are a good person, and you also want to save us when you go down the well." However, you can't give up your life for someone else, that would be too irrational. ”

Xiao Bing was silent for a while, and said, "But your teacher is definitely willing to give up his life for you." ”

Speaking of Chen Dahai, Wu Dongdong glanced at Xiao Bing, and seemed to be a little speechless.

Xiao Bing continued: "In the cash car, an escort's finger was pinched by the door, and there were footprints on his chest. I think that when the beast attacked, he wanted to get in the car to escape, but you were afraid that the beast would also rush into the car, so you grabbed his fingers and kicked him out of the car. Of course, these things you may not have thought about without thinking, just an instinct to survive. ”

"I ......" Wu Dongdong looked at Xiao Bing with some horror.

"Our conversation just now was limited to the two of us." Xiao Bing said: "You are really smart and have a strong ability to survive. In this last days, such qualities of yours are precious, and I am willing to give you a chance. ”

Wu Dongdong opened his mouth and looked at Xiao Bing in a daze.

"People can be selfish, but they can't hurt others." Xiao Bing said: "I told a woman this, and I also gave her a chance. I hope you and she don't let me down. I don't need to say anything superfluous, I'm sure you can understand. ”

Wu Dongdong bit his lip: "You, what do you want me to do?" ”

"Throw the grenade out and jump into the well and I'll catch you." Xiao Bing handed the grenade into Wu Dongdong's hand, then retreated to the well, turned over and entered.

Wu Dongdong put the flashlight aside, took the grenade, looked at it, and suddenly smiled.

"You're an interesting person."

Wu Dongdong put the helmet back on, walked to the well with a grenade, and looked down at Xiao Bing, who was propped up in it with his arm: "Shorten the fuse, and then let me detonate it, so as to test me?" However, your intentions are too obvious, and the performance is blunt, so you should be a little more skillful. ”

"You think so?" Xiao Bing propped up the wall of the well and looked up at Wu Dongdong.

Because of the dimness in the well, Wu Dongdong couldn't see Xiao Bing's expression. "I don't know about weapons, but even if you change the fuse to a short one, it won't explode instantly. You say, if I loosen it here, will this well help me block the impact of the explosion? ”

Wu Dongdong stretched out his hand and hung the grenade above the wellhead.

Boom――――

Deep underground, there was a sudden violent explosion.

Not a grenade, but a tanker truck blew up.

……

As the tanker approached, the leader of the giant rats was extremely restless and issued orders to the beasts. All the beasts attacked the tanker. When the beast's sharp claws and teeth tore open the fuel tank and let the fuel flow out, the sparks of the battery directly detonated the tanker.

With a loud bang, a large number of fierce beasts were blown away and scorched. Because of the distance and the sturdiness of the body, the giant rat leader was not fatally injured except for some scorched hair and burned eyes. However, the explosion thoroughly brought out its ferocity.

With a roar, the leader of the giant rats struggled and slammed out of the pile of rubble.

Without this support, the rest of the rubble was instantly washed away by the water under the huge water pressure. The rumbling water poured into the tunnel like a beast.

…………

"You seem to have said that you should detonate the grenade when the time is right." Wu Dongdong deliberately waited for a while, and then let go of his hand: "It's now." ”

The two grenades fell straight into the well, and Wu Dongdong also hugged his head and fell to the ground.

The grenade did not explode right away.

Bang, Xiao Bing bent his legs and flicked them, kicking out the two grenades. Then he jumped up, grabbed Wu Dongdong who was lying on the ground, and pulled him into the well.

"You're thinking too much, I don't know how to change the fuse of the grenade."

In the loud bang, Wu Dongdong's eyes widened in horror. With the help of the light of the explosion, Wu Dongdong watched as the hut was opened, and a large amount of water poured down from above.

Xiao Bing couldn't withstand this impact and fell into the well. But when he fell, Xiao Bing didn't forget to protect Wu Dongdong.

At the same time, the water from below also poured into the ventilation shaft, quickly lifting the safe house.

At first, because of the twists and turns of the tunnel ventilation shaft, the water flow only slowly pushed the safe house up. But as the water fills the tunnel, the water pressure at a depth of several hundred meters begins to take effect, and the safe house rises faster and faster.

Wu Dongdong was worried that the explosion would be too early, and the scattered stones would not be enough to seal the wellhead. Deliberately waited for a while, and when the pressure below stabilized, the grenade was detonated. So Xiao Bing and Wu Dongdong were washed down by the water and didn't get much high, so they smashed on the rising safe house.

The momentum of the rise of the safe house has not slowed down, and the water flow above it is rising rapidly.

Xiao Bing protected Wu Dongdong under his body and endured the greatest pressure.

With the rising current, the safe house was quickly squeezed out of the ventilation shaft and then pushed to the surface......

Wow -

There was a loud sound of water, and a large splash erupted on the surface of the water. The safe house and Xiao Bing Wu Dongdong flew out of the water together.
