Under the light of the morning light on the island, Chen Zhe drove his car made of solid wood back to the camp slowly, and Meixi and Da Qiao, who witnessed this scene, were simply dumbfounded, suspecting that they were hallucinating.

The two girls looked back at each other, and then they were sure that the picture in front of them was real.

Meixi couldn't help but ask, "What's wrong with Chen Zhe...... Went out early in the morning and drove the car back?"

Da Qiao's focus is on the other hand: "Didn't you say that the car ran out of gas? Where did Chen Zhe get his fuel?"

Meanwhile.

In the live broadcast room of Wilderness Survival.

Netizens were also shocked by Chen Zhe's sudden operation.

Obviously, I saw with my own eyes last night that his car had exhausted the last fuel and broke down directly outside the camp, and he couldn't even drive back for the last part of the journey, so why was the car able to start again early this morning?

Could it be that overnight, the fuel in the tank went up again?

Netizens have expressed their magic:

"What's going on? Where did Chen Zhe get the oil?"

"How can the car start again?"

"What happened?"

"I know, Chen Zhe is doing magic again. ”

"Chen Zhe is absolutely good at magic, for sure!"

“......”

Even the host He Chen felt that things were a little strange, and he tilted his head to ask the three guests next to him.

"I don't know if you paid attention to our live broadcast yesterday, the situation is like this, let me give you a brief description - yesterday Chen Zhe's car broke down directly on the side of the road because of lack of fuel, and he and Ouyang Meixi finally had to walk back to their home......

There is no gas station on the island, and it is impossible to obtain fuel resources directly, but Chen Zhe is so magical, he actually got up early in the morning and drove the car back without fuel.

What do the three of you think is going on? How did Chen Zhe do it?"

One of the guests speculated: "Could it be a reward from fans?" Chen Zhe's fans or Da Qiao Xiaoqiao's fans gave him a bucket of diesel or something?"

"It won't. He Chen shook his head decisively and said, "The tips of fans are recorded in our live broadcast room, and from last night to this morning, no one gave Chen Zhe a reward."

His last reward record shows the self-heating hot pot that Lin Kongkong's fans gave him a reward. ”

"This ......" Several guests heard this, and they all fell into a myth.

Since no one gave Chen Zhe a reward for fuel, where did he get his fuel? It can't be made by himself, right? It's unbelievable.

Seeing that several guests all showed confused expressions, He Chen knew that they didn't know why, so he could only point to the big screen and said, "It seems that it is difficult for you to reveal the truth of the matter, in this case, we might as well let Chen Zhe reveal it himself." ”

The guests nodded their heads:

"That's all there is to it. ”

"I can't wait. ”

"I want to see how Chen Zhe solves his fuel problem. ”

......

The other side.

Chen Zhe's camp.

He had slowly driven the car under the banyan tree.

After making sure that there were no obstacles in front, Chen Zhe turned over and came from the front to the back, turned off the engine of the car, and stopped the car completely.

At this time, Ouyang Meixi and Da Qiao had already walked down from the tree house, and the two of them looked around the car in shock and curiosity, as if they were looking for what Chen Zhe had done to the car, so that the car drove back.

After seeing that this car was still yesterday's car, and there was no difference, the two couldn't help but start asking questions.

"Chen Zhe, how the hell did you drive this car back?" asked Mi-hee.

"That's right, isn't the car out of gas? Why is there gas again?" Da Qiao was also at a loss.

Chen Zhe smiled lightly, then unscrewed the lid of the fuel tank, pointed inside, and said, "Look, the fuel tank is full." ”

The two girls looked and saw that the fuel tank was full, and by the bright sunlight on the island, they could see the clear and swaying fuel inside.

"Did a fan give you a tip for fuel?" Da Qiao couldn't help but speculate, "Is it Lin Kongkong's fan again?" or Lia Tila's fan?"

"Neither. Chen Zhe shook his head and said, "I prepared this fuel myself." ”

"It's you...... Prepared?" Da Qiao and Mi-hee were shocked, both of them in disbelief.

"Chen Zhe, this engine burns diesel, as far as I know, there seems to be no natural diesel in nature, can you prepare this?" Da Qiao asked shockedly.

"There's no natural diesel in nature, and you need oil to make it, and I can't even find oil on this island. Chen Zhe said honestly.

"And how do you prepare fuel?" asked Big Joe again.

Chen Zhe smiled and said: "Energy is not only gasoline and diesel, in fact, there are many new energy sources that can replace them, such as one fuel - biofuel. ”

"Biofuel?"

At this time, Da Qiao and Mei Xi were a little dazed, and the two of them obviously did not dabble in this range of knowledge.

At this time, Chen Zhe continued: "The so-called biofuel is a kind of efficient fuel obtained by using vegetable oil and animal oil by interacting with ethanol......

As long as the lamp oil and ethanol are mixed together and heated at a certain temperature, the two substances can react together to produce biofuel that can replace diesel. ”

After listening to Chen Zhe's explanation, the girls suddenly realized.

Although they didn't know how to make biofuel, it was clear that Chen Zhe had found a good way to solve the problem.

And at the same time.

In the live broadcast room of Wilderness Survival.

He Chen and the three guests also got answers to their questions.

"Biofuel......" He Chen squinted his eyes and asked with some doubts, "Among the three teachers here, has anyone learned about this knowledge?"

At this time, a biology expert, Mr. Wu, nodded and said: "I have some research in this area, and I have also inspected some factories that prepare biofuel. ”

He Chen hurriedly asked, "Is what Chen Zhe said correct? Is it possible for him to prepare biofuel under such conditions as the island?"

"Well...... Teacher Wu frowned and said, "Theoretically, it's possible, after all, Chen Zhe used the fruit of the tung tree to squeeze out industrial oil, and obtained a large amount of ethanol by making wine."

However, industrial oil and ethanol must react under very harsh conditions before they can be used to produce biofuel, which is a very difficult step. ”

"Isn't there such a condition in the wild?" He Chen immediately asked rhetorically.

"It cannot be said that such conditions are not available in the field at all, it can only be said that the conditions in the field are relatively difficult, and the success rate of preparing biofuel is relatively low...... But we have also seen that Chen Zhe successfully prepared biofuel in such a difficult environment, which shows that as long as the technology is excellent, nothing is impossible to achieve. Teacher Wu said.

He Chen also deeply agreed with this, nodded and said: "That's right, it seems that as long as the technology is excellent, there is indeed nothing that cannot be achieved."

Chen Zhe once again proved this with his amazing strength, even in the wilderness, he was able to refine biofuel that can replace gasoline and diesel. ”

But at this moment, a guest sitting next to Mr. Wu, Mr. Zhou, suddenly said, "But there is a problem at the moment. Although Chen Zhe has prepared biofuel, the fuel consumption of the car is very large, and the camp also burns some lamp oil every night.

Relying only on the lamp oil he squeezed last time, I'm afraid it won't be enough, right?

Chen Zhe uses the ancient method of oil extraction technology, which is very hard to extract oil...... Chen Zhe can't always squeeze oil through the ancient method like this, his body can't bear it if it goes on like this. ”

Mr. Zhou's question immediately resonated in the live broadcast room.

The host He Chen nodded and said, "That's right, Mr. Zhou's question is indeed a good question. ”

Teacher Wu also frowned and said: "It's fine if Chen Zhe and they use cars occasionally, but if they use cars frequently, the production capacity of biofuel is indeed a big problem."

In fact, their consumption of lamp oil every night is already very large, Chen Zhe already needs to quickly replenish a batch of lamp oil, and now with the preparation of biofuel, how can he make up for the lack of production capacity?"

Teacher Zhou looked at Chen Zhe in the camera and said with a smile: "I think Chen Zhe will soon find out about this problem, see how he solves this thorny difficulty, I believe he will hand in a satisfactory answer." ”

......

Teacher Zhou is right, Chen Zhe did quickly discover this problem.

In fact, Chen Zhe discovered the problem earlier than he - as early as this morning, when he went out to prepare biofuel, he had already found that there was not much lamp oil on the camp.

If you want to make lamp oil, you can only pick the fruit of the tung tree, and then use the ancient method of pressing to press it little by little.

Chen Zhe had to swing heavy wooden stakes and repeat the tedious and laborious piling movements again and again.

The last time he prepared lamp oil, Chen Zhe was almost not paralyzed the next day, even though both of his arms had been upgraded by the system, but the amount of exercise pressed by the ancient method was still unbearable for him.

He didn't want to be an oil press again, because once he squeezed oil, he could lose a layer of skin.

Looking at the oil cylinder that had bottomed out, Chen Zhe fell into deep thought.

"What if only there was a fully automatic oil press......

Troubled by this question, Chen Zhe walked towards the outside of the camp.

Today is fortunate to be another sunny day, just enough to go to the surrounding woods to relax.

Walking out of the camp along the banyan forest, Chen Zhe walked all the way to the river, the air by the river is the best in the woods, and the breeze is always exceptionally refreshing.

In addition, Chen Zhe's sailboat has been docked at the river, and I don't know if the sailboat has been washed away by the wind and waves in the past few days, so I can take a turn by the river to see the situation of the sailboat.

Walking slowly to the river, I saw that the sailboat was still docked in its original position, and the rope was firmly tied to a palm tree by the river, so even if the current was strong, it did not wash the sailboat away.

Chen Zhe walked to the side of his masterpiece, looked up at the turbulent water in the distance, and the bottom of the oil tank still appeared in his mind, and the problem of oil extraction returned.

"I don't want to be a coolie anymore, and I have to ......tire me out if I press oil again."

Chen Zhe was painfully entangled in his heart.

At this time, looking at the flowing river in front of him, his eyes suddenly lit up.

The flowing river contains a large amount of kinetic potential energy, and the kinetic potential energy is just enough to be utilized.

Flowing water is a very common source of energy in nature, and the construction of hydroelectric power plants is actually a good use of the kinetic potential energy of flowing water.

The use of flowing water by the ancients began a long time ago, and the waterwheel is an invention created by the ancients using flowing water.

Thinking of this, Chen Zhe's heart suddenly brightened!

"I could have built a waterwheel and used it to squeeze oil! The river is so turbulent in the rainy season, and there is a large amount of water flowing down with power potential energy every minute and every second, if this potential energy is used, then it is not easy to squeeze lamp oil?"

With a plan, Chen Zhe began to put it into action.

However, just as he was about to start designing the waterwheel, Chen Zhe suddenly realized a problem.

He is not omnipotent, nor is he omniscient.

As a traverser, he just has more knowledge than ordinary people, but that doesn't mean he knows everything.

He was able to build a hand-spinning wheel because he had seen others weaving cloth when he was a child.

He was able to build a solid wood car because he used to play with four-wheel drive cars when he was a child.

But for the waterwheel...... Chen Zhe really knows very little.

After all, there is almost no remnant of this ancient tool in modern society.

Chen Zhe didn't even know the structure of the waterwheel, so how could he build it?
