"Maybe you can try electrolyzed water?" Looking at the switch next to the door, and then looking at the water dispenser full of water, Lin Qiuran rubbed his chin and said, "Anyway, the room is full of flammable and explosive gases, and any more hydrogen is nothing." The extra oxygen is net earning, and it can buy time! ”

This method is a bit reliable? Everyone's eyes lit up and they pondered.

Suddenly, a majestic voice sounded: "Electrolyzed water needs direct current, right?" ”

Except for Xiao Ling, everyone glanced at Peng Shuai in surprise, and they didn't expect that it would be this guy who raised this question.

"Why, I'm not allowed to do chemistry?" Facing everyone's shocked eyes, Peng Shuai rolled his eyes.

"That's right, he's really good at chemistry." Xiao Ling praised his best friend, "Because the teacher who taught us chemistry at the beginning was a big beauty." ”

Everyone laughed, and Peng Shuai pointed at Xiao Ling.

Lin Qiuran was happy and pointed to the TV hanging on the wall: "There should be a rectifier in there, which can turn alternating current into direct current." And...... Alternating current and direct current do not affect the electrolysis of water, but when doing experiments, one electrode is needed to decompose hydrogen and one electrode to decompose oxygen, so as to facilitate the verification of the effect of electrolysis. If you use alternating current, the electrodes on both sides are mixed with hydrogen and oxygen, so you can't verify it......"

Although there is no way to verify, the hydrogen produced is the same as oxygen, and everyone understands it.

But...... On second thought, this method is not so reliable, since electricity is needed, the switch next to the door will also use electricity. Why does pressing a switch detonate the gas, but electrolysis does not?

Sparks are very random.

"That'...... Retrofit the switch into an arc extinguishing switch? It seems that you need to use oil......" Lin Qiuran pressed his fingers to the center of his eyebrows. Keep searching in your mind. He had a database, but without the help of the console, he could only recall it in his head. The efficiency is much slower, and many materials are incomplete, and some even have only index catalogs.

"It's a bit of a ...... Too professional, right? While Lin Qiuran was thinking, Peng Shuai couldn't help but say.

"Indeed!" Pu Rou agreed, "So I prefer to solve problems with simple methods!" As she said this, she jerked open the carpet in the corner. Everyone noticed, not knowing when. She had already dug a hole in the floor.

Of course, the hole was not dug out, it was all steel! It is a screwdriver and pipe wrench, "whooshing ......" twisted raw. Be able to manifest all the tools you want. This makes the job surprisingly easy.

She found a well-fitting gap in the ground, pried open it with a screwdriver, and found an exit to the outside world. Although it is only a dozen centimeters wide, it is also an export after all. There was fresh air coming out of the hole.

The most obvious is that the system countdown has slowed down. Deduct two seconds, return one second, deduct two seconds, return one second...... In other words, the remaining nine minutes can basically be used as eighteen minutes.

And...... "Oh oh, time has changed." If there is a hole here, there may be somewhere else! Peng Shuai was the first to shout.

Lin Qiuran was stunned: "What Xiao Ling said just now, this is not an ordinary room. We are now on some kind of transport. As far as I know, vehicles are rarely made of cast iron in one piece. Because then it would be too cumbersome to design by machining! Except for a frame, the rest of the house is most likely assembled with prefabricated iron plates, some by rivets, and some simply by screws. ”

"If you find the right way to dismantle it, you can tear down all four walls of the room!" He said excitedly.

That's right, that's what it means! Xiao Ling nodded secretly, Lin Qiuran said that he had actually thought of these things a long time ago, and he just didn't say it on purpose. If the friends still don't have a clue for two minutes, he plans to give a reminder.

Play the game, the picture is happy.

After discovering the clue, everyone immediately rushed to all parts of the room excitedly, groping for the walls and floors.

It didn't take long for them to make their own discoveries.

"Wow, this slit is too thin, isn't it? I didn't even see it when I got in front of me, Pu Rou, how did you find it? Peng Shuai screamed. He was right, there were indeed cracks in the walls and floors, but they were so thin that they were thinner than a hair, and they were hard to spot in dim light, whether they were touched with their hands or when they looked closely.

If you don't have a goal in advance and rely on luck, it is almost impossible to have an attribute below ten.

And this series of discoveries also proves that this path is absolutely right.

Pu Rou grinned and glanced at Xiao Ling: "I'm just standing on the shoulders of giants." ”

Wei Feifei's mouth pursed slightly, and a handful of golden powder appeared and smeared it on the ground. Under the illumination of the light cluster, the golden light flashed, and then it was easy to see the thin cracks in the golden light.

Equipped with an ultra-thin screwdriver, find the corners of the seams and insert them accurately...... The former method was learned from Xiao Ling, and the latter method was the practice of her nursing profession.

The speed was very fast, and in the blink of an eye, half of the iron plates on the wall were pried off, and suddenly there was a cheer: "This!" This! ”

Unlike the ultra-thin, delicate and sturdy exterior wall, when you peel it off, it is a stupid black and thick inner wall, as if it were ...... iPad, under the smooth and bright surface, is just a plate and line chips, at most they are arranged a little tighter, the layout is a little more regular, and there is no technological beauty on the surface at all.

Peeling open the outer wall, hidden inside, there was a boxy iron plate, which was fixed by thick screws on all sides. It feels like the whole wall panel can be removed as long as the screws are twisted, and the rest of the work is much easier.

Not only that, at the same time that Wei Feifei made a discovery, everyone basically completed their first round of disassembly, Peng Shuai is the wall skin is meaningless, Xiao Ling removed the TV and groped to open another vent, plugged with wires, TV signal cables, etc., the area is a little larger than what Pu Rou found.

The countdown to the room then stopped. Not only that, but every three or four seconds, it even replies by one second......

By this time...... Lin Qiuran put down the hand raised towards the vent. The vent was blocked by the strip of cotton cloth he had stuffed into at this moment.

This is certainly not enough to stop the perfusion of the vent to the room, so ...... The strips of cotton cloth and the like had been soaked with water from the water dispenser before they were stuffed in. After stuffing it, he even activated his ability to freeze it.

This didn't make sense before, but it made sense when the wall was opened.

Sure enough, after the blockage, the countdown reply speed was a little faster.

After doing this, Lin Qiuran ran to the iron plate found by Wei Feifei, showed a large plate pliers, compared them with the screw caps, corrected the caliber, and struggled to start twisting, and at the same time really found the engine oil in the house, and lubricated the oil while twisting hard, so as to prevent sparks from rubbing too hard.

Everyone writhed and muttered in their hearts: I rubbed this steel plate too thick!

Why? Because a few minutes passed, the four of them worked together, and each of them twisted out the screws with a diameter of about three centimeters and extremely fine threads for at least ten centimeters, but the screws were still firmly embedded in the steel plate, and there was no meaning to the end!

How thick is this steel plate? A foot? If it weren't for the other vents, the countdown would have been increasing, and it would have been ten minutes back, and the countdown time would not have been enough to twist the screw!

Twist, twist! Twist, twist! Everyone worked together, their foreheads sweating, and as they were fighting, ......the room suddenly trembled and shook violently, as if some kind of pressure had reached its limit, and some kind of patience had reached a critical juncture.

"Boom! Bang! Bang! "Suddenly, several pieces of wall skin burst at the same time, and the wall panels, including screws, burst out!

The friends shouted bitterly!

Someone was cut by a steel wall panel, and blood flowed profusely; Someone was shot by a screw, as if he had been shot, and there was a bloody hole on the surface of the body, but it was not pierced, and the screw remained in the body.

They each covered their wounds, and they didn't have time to check the injuries, and from the holes in which walls, the "lala......" turbulent water gushed up. It's really gushing. The pressure of the water flow was extremely high, and it shot out from the wall on this side, and the landing point must have been on the opposite wall, and even the position was not much lower than the source.

The friends were caught off guard, they were poured all over their faces, and they were even slammed on the wall by this high-pressure water dragon, and they finally got rid of it.

Except for Peng Shuai, who has rough skin and thick meat, most of them shivered. This water is so cold!

The current was so great that soon the ground was red and muddy.

That's the blood shed by the friends! But it's not just blood, the water itself is muddy, as if it's ...... It has been accumulated for a long time and melted into rust.

"Ah......h The crowd turned to look at him. Then he took a step back and pulled it off the wall against the current. The right side of the chest is bleeding!

The water sprayed just now, and he was caught off guard by being sprayed against the wall and hit the screw hard. The three-centimeter-thick screw pierced his chest, broke his ribs, and plunged into his lungs.

Exhausted and out of his predicament, he coughed loudly. The corners of his mouth couldn't help but spurt blood, and he was seriously injured.

"It's all my fault! It's all my fault! Lin Qiuran couldn't help but blame himself, "If I hadn't blocked the air intake with ice cubes, it wouldn't have been like this!" He felt that his act of blocking the air intakes increased the pressure in the wall, and then he didn't know what setting was touched elsewhere, which caused the flooding.

"Don't be naïve. It has nothing to do with you! Xiao Ling covered his shoulder, which had been cut by a thin plate and was bleeding so much that he couldn't exert himself, "It's because the countdown has returned to ten minutes." ”

"Ten minutes?" Everyone looked at the system. Sure enough, the countdown time is now stuck at the ten minutes when it started.

Estimate...... This is the condition that triggers the avalanche, otherwise where would it be so coincidental?

At the same time as the explanation, Xiao Ling covered his arms and rolled and crawled to avoid the jets of water that shot one after another, and came to the door, shouting: "All exhale!" Get into the water! ”

The friends were stunned and understood, and they all fell down with their heads shot, lying down in the stagnant water that was already two feet deep.

Xiao Ling also exhaled, suddenly pressed the switch next to the door, and at the same time lay down as fast as possible!

However...... The door opened, and the scene outside the door stunned every little friend! (To be continued......)
