Haige was tempted to say to Weddle, "Maybe you're one step away from success, and you'll be able to get Super Metal in your next experiment?" Even if the earth only lives for a minute, there is still hope! ”

But he didn't have the courage to say a word, so he could only stand with his head down, like a child who had made a mistake. Unsuspecting bystanders are likely to think that the failure of the Wedel test is caused by him.

After a long time, he said like a mosquito: "Adding a filter will solve the problem?" ”

Sensing his nervousness, Wedel hurriedly controlled his temper and said in a soft tone, "Don't worry, my child, within a week, the purple apricot tree will be full of new leaves, and the experiment will begin again." I can always adjust the ratio of boric acid to the optimal value, and next time I promise that I will not let the mesophyll remain in the refining pot! As you said, I need to add a strainer to the refining pot, yes, that's it, add a strainer next time! ”

At the end of the day, he suddenly showed nervous excitement. Seeing this, Hai Ge also had the courage to say: "Failure is the mother of success, you will definitely succeed next time, I also promise!" ”

"Oh? Hahaha~"

Seeing the appearance of the child's hands and feet not knowing where to go, Wedel, who was in extreme frustration, actually laughed, "This little guy is really interesting! He thought.

Then, when there was nothing left to do in the workshop, Wedell stood up and patted Hai Ge on the shoulder and said, "Come on, friend, we have time to talk about it now." I think you're hungry, so try Aunt Lucy's handiwork, and even a handful of grass can be made into a meal in the blink of an eye. You have plenty of time to enjoy it slowly. ”

When it comes to food, Hai Ge realizes that he is hungry. From walking into the light-controlled corridor to watching Weddle refine plant metal, to refining failure, at least a day has passed, but he still hasn't even drunk saliva.

But he was not hungry enough to eat at once, and though he was eager to see Aunt Lucy's cooking at once, he made a request to Wedel, and that was to go around Lying Elephant Mountain.

"Oh? Child, are you interested in that mountain? Wedel looked a little surprised.

Hai Ge nodded hesitantly and said, "I beg your pardon, I'm just curious, and I don't mean to snoop into the secret of the Light of Salvation, if you find it inconvenient......"

"Hehe, there is no inconvenience, I just impressed your spirit of exploration. The huge plasma fusion engine with the Earth's starting engine and its operating control room are located on that mountain, and it is not safe for humans to approach it directly, so it has always been occupied by AI intelligence. ”

"It turns out that the scientists of the Light of Salvation only operate remotely, and that's for this reason." Haige was disappointed and had to dismiss the idea of visiting the giants up close.

But what Wedel said next made him happy.

"Child, the reason why such a core device is hidden in the Lying Elephant Mountain is because it is impartial, and the mountain range is pressing on the center of the earth in the real sense, so the gravity there is the greatest, and when the engine starts one day, it can maximize the reverse thrust of the center of the earth. In fact, as far as the device itself is concerned, it is extremely radioactive, and without the protection of the underground plant kingdom by the magneto-photomask, we would not have been able to live as close to the Lying Elephant Mountain. ”

"You mean, Reclining Elephant Mountain and the Redemption Light Headquarters are two parts in the plant kingdom, separated by an invisible shield in between?" Haige asked excitedly.

"Yes," said Weddle, "I think you'll see a huge wheel when you get here. ”

"Yes sir, I thought it was a dismantled part from a waterwheel!" Haige honestly reveals his thoughts.

"Hehehe~" Wedel was happy again, "Child, the waterwheel is not suitable for the underground plant kingdom, most of the animals and plants here can independently draw the water they need from nature, without human control. In fact, when they grow on U stars, they never need water, and they only need to absorb light to thrive. ”

"All the flora and fauna here were brought by you from U Star?"

As he spoke, he came to this level again, and Wedel no longer avoided it, nodded and said: "It is indeed the species I brought, but I have made various improvements to them, the purpose is to hope that they can adapt to the environment with water like the creatures on the earth, so that they will not be eliminated in the fierce competition of natural selection, and in the future, the vitality of the U star can be continued." ”

It's no wonder that the monster from the U star can come out of the river, it turns out that it has been improved by Wedel! It's amazing, and Hai Ge feels dizzy again, but more surprising things are yet to come.

Wedel turned the topic back to the wheel: "The wheel you see is only the above-ground part, in the granite-paved underground, where you walked, there is a buried machine covering an area of nearly 10,000 square meters, which can convert light energy and heat energy into electrical energy, a total of ten large energy transmission pipelines go straight to Woxiang Mountain, and connect with the main engine of the earth's starting engine. It is a set of plasma optical flow reflective generator sets with a rated power of tens of thousands of megawatts, ensuring the power supply of the entire underground world. ”

"At our feet, there is a whole set of large generator sets? Or rather, a ...... that is more powerful than any power plant on the ground."

Haige wanted to talk about the power plant, but he felt that the word was too small to describe the underground generator set, so he got stuck.

Wedel relieved him, saying, "You can think of it as the sum of the earth's power plants, because even if it also supplies power to the ground, it can take care of it." The light energy output from the earth's engine is absorbed into the energy pipeline before it has time to disperse into the air, and is relayed to the underground energy conversion device of the Salvation Light headquarters, providing sufficient power for this huge underground plant kingdom. As for the unconverted light energy, it is all transmitted to the solar panels covering the surface of the runner, which are reflected into the core atmosphere similar to the earth's atmosphere, creating a sunshine effect with moderate luminosity and pleasant climate. ”

Hai Ge didn't blink when he heard it. All of this that Wedell has laid out in the Earth's core can only be regarded as a surreal myth to earthlings, but on his U planet, perhaps it is as ordinary as hydroelectric power or wind power here, right?

But in any case, under the guidance of Wedel, the earth's starting engine will not only undertake the important task of pushing the earth out of the current orbit, but also turn the earth's core world, which originally only had rock crystals shining, into a nature like spring all year round, forming a complete ecosystem, which happened under the action of U-star technology, iron-like facts!

Haige asked curiously, "What about the rotation of day and night?" Is it in this underground world where there is only day and no night? ”
