Fat Dahai went out the door, lifted a box of explosives, and threw it hard under the wall. The box of explosives flew far away in an extremely exaggerated way, landing exactly where the black fog and the tree roots were most intense. Fat

Hai gasped for breath twice and lifted the 38 big gayer, followed by a "ping" sound, and after a pause of a few seconds, he only heard a loud "boom", and a bright fire broke out on the ground.

Bai Hewu took advantage of the firelight to look at the black mist, which was dispersed a lot by the shock wave, and a dragon-shaped white shadow with sharp lines and sharp edges faintly appeared under the firelight. The fat sea at this time

The distance from the explosion point is not far or close, and the firelight and the fat sea also quickly ran back to the observation room, and then closed the door with a bang.

"The sea, can you do it all at once? Hey? Why is your face blue again? Tang Tiezui said.

"Who knows? Let's wait and see. If it doesn't work, I'll give it to him again. ”

Fat Sea did not answer the latter question. However, Bai Hewu's brows furrowed when he heard the words that his face turned blue.

As he spoke, there was a pop outside the door, and by the light of the flashlight, it was obvious that the big thing wrapped in black fog outside had fallen back into the river. Immediately after that, a great deal of black came out of the surface of the river

Fog. The thick black fog didn't take long to completely obscure the already unclear vision. Seeing this, Bai Hewu hurriedly closed the door tightly.

"The sea, this place is your way. In my opinion, you should come up with an idea first! The white crane danced.

"Don't worry, I guess this thing will fall apart. Let's sit down and wait. ”

"Wait for sure, it's not wrong that the black fog can disperse. But don't forget that the river below is constantly producing black fog. It's unknown when we'll be able to get out. So say me

We can't wait forever. Professor Lan said and was about to open the door: "You guys stay away, while the fog is not too thick now, let's put it in a little bit and try its toxicity." ”

"Alas, alas, alas. That's not going to work. The fat sea suddenly rushed out and grabbed Professor Lan. You don't have to try, the black fog is definitely very harmful to the body. ”

"How do you know?" Tang Tiezui asked.

"Actually, this is very simple, you can see by looking at this door, this door is sealed, obviously to prevent anything from penetrating. What else could that thing be out of the black fog, you say? ”

"Since that's the case, I think we'll open the door and run out, or ............" Tang Tiezui shut up again when he said this, but everyone understood what he meant.

"That's not to mention, if we're wrong, this black fog shouldn't last long." Fat Dahai said this, looked at the three of them, and continued: "There are only two stone bars here as stools, so to speak."

The people in the observation room won't stay here for long, otherwise there would definitely be such facilities as beds and toilets. ”

Hearing Fat Dahai say this, the other three all calmed down and did it on the stone.

Soon after the four of them sat down, they could see through the observation window that the black fog outside was getting thicker and thicker. Except for Fat Sea, the other three were worried about the black fog. At that moment, there was a slight footstep outside the door

Sound. A few people still didn't know what was going on, and there was a very soft metal crash outside the door.

"Tsurumae, don't go until the situation is unclear now." Bai Hewu just wanted to check it, but was stopped by Professor Lan.

After a while, the sound outside the door completely disappeared, and Professor Lan picked up the flashlight and shone around the door through the observation window, until he stared at the pain in his eyes and saw nothing.

"What would come to such a place?" Professor Lan turned to the other three with a pensive expression.

"In my opinion, we don't care what it is, just sit here and wait for the fog to clear!" As soon as Tang Tiezui finished speaking, he stood up suddenly: "No, nothing else will be."

Come here, it must be the gunman above. Hurry up and take a look at this door. Tang Tiezui quickly walked to the door and pulled twice on the doorknob, but the door really couldn't be opened.

"Don't worry, let me see." Professor Lan stepped forward and looked sideways through the glass window, and faintly saw a stick of unknown material stuck in the doorknob.

"Looks like we're going to change our plans." As he spoke, Fat Dahai picked up the 38 big lids, and after a few gunshots, three holes appeared in the door. After the gunshot, Fat Dahai stepped forward and flew up

Kick on the door. Unexpectedly, the door was unusually strong, and it did not waver at all. Fat Dahai still didn't give up, took two steps back and raised it again.

"Stop the sea, stop fighting." When Tang Tiezui'er saw it, he quickly stopped him.

"What are you doing, I don't want to spend the New Year here?"

"Look at those two bullet holes first."

"This ...... Where does this water come from? ”

Fat Dahai looked towards the door, and the two bullet holes just now were already seeping water inside.

"In the dark river, this dark river must be connected to the river outside the peach forest on the ground, I guess it must be because of that water monster that the water has not risen. In this way, the water will soon be submerged

Room. At this time, Professor Lan was no longer calm.

"You want to lecture and go back to school. We'll stay here when the water fills up. Tang Tiezui walked to the door and blocked the two leaky single holes with his fingers. But he's clear

Chu did this just to serve as a psychological comfort. As long as they can't open the door, even if the house doesn't leak, they won't last long.

"We had to find a way to break down the iron gate quickly." Professor Lan turned his head to stare at the remaining crates of explosives.

"I said Professor Lan, this room is not big, you don't want to use explosives, do you?" Tang Tiezui said in surprise.

"There's no other way but explosives."

Professor Lan began to take off his hazmat suit as he spoke. "Take off your protective clothing, too!" Otherwise, the water will come in and you won't be able to get out. ”

"Push a stone bar to the door." As soon as the four of them took off their protective suits, they pushed the stone bar down the door with Professor Lan.

"The sea will make two more holes in the door, so that the water will come sooner."

After two more gunshots, the water flowed faster. At this time, Professor Lan also broke open a box, poured out half of the explosives inside, and put it on the stone bar at the door.

"Well, it's up to you to make or break it. Prepare your guns in the sea and try to wait until the water is a little deeper before shooting. After the shooting, everyone fell into the water together. ”

After saying this, Professor Lan and the three of them retreated to the back end of the room and lay down. Admittedly, this is an extremely risky approach. But at this moment, the four of them have no other way.

Professor Lan shone his flashlight at the door, who was still flowing unhurriedly, making a sound of a soot. Everything seemed so silent, and the four of them were holding their breath and just hoping that nothing would happen again

What's wrong.
