Chiba is not sure how long cooking oil can turn a gasoline engine, because the previous research data on cooking oil only has a diesel version.

In that study, cooking oil successfully drove the diesel engine, and it was barely functional. But the viscous cooking oil quickly clogged the engine, forcing researchers to work hard to clean the blockage.

Now, it's time to pour cooking oil into a gasoline engine...

After a sigh, Qian Yu came to the kitchen with a hard head.

It is true that edible oil can be used directly in the engine, but it needs to be heated to the point of close to the boiling point before it can be compression-ignited, and the principle of a gasoline engine is probably not much worse.

"Are you really going to pour cooking oil directly into the engine?" A playful tone suddenly appeared behind Qian Yu, who was about to pour cooking oil into the oil pot.

“！” The look of surprise on Qian Yu's face flashed, but when he turned to the person who spoke, his expression had already changed to indifference.

"What do you have to say?"

"Add baking soda, filter, take the medium liquid, and then decide how much cooking wine to put depending on how many lives you have." Gray Yuan said lightly. "Biodiesel is a little more reliable than edible oil."

"Thank you." Chiba took out a bottle of baking soda from the cupboard.

"Anyway, be careful later." After Ash Yuan Wai said this, he immediately added. "It doesn't matter if you blow yourself up, it's not fun to blow us up."

"Don't worry... As soon as Chiba was halfway through speaking, the kitchen light suddenly dimmed.

"Again?" Chiba's expression turned to anger. "I'm afraid it's going to kill again."

"It's... Gray Plains' face turned to fear. "Not good!"

"Boom!" The sound of the raging water crashing against the wall reached the ears of the two men.

Before the two of them could react to what had happened, the rampage of water had already rushed into the kitchen, sweeping them into the raging turbulence.

The two of them bumped into something and were blocked by the rushing water. Moments later, the thing was washed away, and the two were swept up in the water again.

The turbulence around him was very chaotic, and Qian Yu couldn't tell the difference between up and down, left and right, so there was no way to adjust his attitude and ventilate the water. I could only hold my breath in the water, begging for the current to stabilize as soon as possible.

。。。

When the surrounding water flow environment was relatively stable, Qian Yu, who was about to suffocate, determined that he was up and down, left and right, and then jumped out of the water.

He found himself in a safe passageway, and the safe staircase leading to the water building in Lele Plaza was more than a meter above him.

"I see... As for how he was brought here by the current, Qian Yu basically had a number.

Most of the cement piled up behind the security doors has been washed open.

Although the compressive strength of 525 cement is 52.5 megapascals per square meter, it can theoretically withstand the pressure of 5,000 meters underwater. But that's the compressive strength, and if the water hits the safety door and the cement behind it, breaking open the part of the cement that connects to the ground, it doesn't take that much force at all. That's why I was swept from the kitchen into the safety staircase by the flow of water, and then rushed here...

Wait a minute, I wasn't the only one in the kitchen at the time...

Qian Yu hurriedly looked around for the traces of Gray Yuan Wai. "Gray Plains? Gray Plains? ”

No one responded to him.

Could it be that she has actually gone ashore?

With this in mind, Chiba swam to the side of the staircase that was out of the water and walked out through the exit of the staircase. The tram they were riding on was stopped in front of him.

Gray Plains mourning is not here...

Qianyu's anxiety was even worse, and she took out the seamless umbrella in the backpack she was carrying, smashed a vending machine next to her, and took out two bottles of drinks. After opening the bottle, the water was discarded and two bottles of air were filled. After that, he hurriedly returned to the safety staircase and observed the situation around him.

Now the current water has basically stabilized, if Gray Yuan Wai has not been able to come up, I am afraid that something is wrong.

Qian Yu dived directly into the water with his eyes open, ready to search for Gray Plains.

Since he can be washed up by the water, it means that Gray Yuan can also mourn. And the only reason she didn't get rushed up was because she was stopped somewhere by a railing or something, so she couldn't get up.

Qianyu, who had just dived half a layer, suddenly resurfaced and began to breathe.

I was too anxious just now, and my heart rate was very fast. In this way, the rate of oxygen consumption will be very fast, and it will not be able to sustain the gray plain mourning at all.

Chiba began to use abdominal breathing, incorporating the air from the lower half of her lungs into the breath exchange.

You can't force yourself to inhale to the point where you can't hold it anymore, or you will increase your heart rate. With the right amount of gas and a calm mood, this is the way to stretch the dive time to the longest.

Calm down... It doesn't matter if she drowns for another minute or two, her brain can hold on for a few minutes.

After a few seconds, Chiba, who had regained his composure, re-entered the water.

Illuminated by the emergency lights of the safety staircase that can operate even underwater, Chiba searches for the trail of Gray Plains.

After exploring two floors downward, Chiba spotted Gray Plains Wai holding onto the railing and slowly heading upstream.

Qian Yu suddenly relaxed, approached Gray Yuan Ai, and prepared to take her up.

However, just as Qianyu approached Gray Plains, Gray Plains Mourning suddenly began to convulse.

Qianyu immediately realized that something was wrong, and was about to stay away from Gray Yuanai, but was grabbed by Gray Yuanai's wrist, and even an air bottle in Qianyu's hand was taken out of his hand and helped up.

Bad... In the face of drowning, you are still so careless...

Because she was close to suffocation, she couldn't continue to keep her sanity, and now she was like seeing a life-saving straw, and seeing a living person was like holding on to it.

Qianyu tried to break free, but was pulled directly by Gray Yuan Wai to his side and hugged him firmly.

“！！！” Qian Yu glanced at the gray plain mourning who was clinging to him, and a trace of determination flashed in his eyes. Although it doesn't feel bad to be stuck to a girl like this-

Gray Yuan Wai put his head on Chiha's neck, and locked Chiba tightly with his limbs.

However, if you continue like this, you will die!

Qian Yu let go of the water bottle in his other hand, and then used his two hands to open Gray Yuan's arms. Immediately after, Qian Yu grabbed Gray Yuanai's neck, and his two hands surrounded Gray Yuanai's neck, and the two thumbs were exactly at the position of the arteriovenous plexus on the left side of Gray Yuan's neck. After a few seconds of compression, Gray Yuan Ai lost consciousness and his body went limp.

Qian Yu sighed in his heart, and pulled Gray Yuan Mourn to start floating urgently.

Well, you need to find a bottle before that, otherwise you may not have enough oxygen.

Qian Yu grabbed a bottle, exhaled a string of bubbles, and stuffed the bottle in his mouth to replenish oxygen.
