"Of course it can't be, my child." Wedel said, "Where is the complete nature without night?" The night plays a non-negligible role in the metabolism of living organisms, and ensures that the sunlight does not increase all the time, and the world can always be in a constant state of temperature. In the Redeeming Light workspace, we have a dedicated climate-controlled room, where one of the tasks is to rotate day and night upside down. The only difference from the Earth's surface is that the duration of day and night is equal through artificial rotation, which means that the underground plant kingdom spends 12 hours a day between dawn and darkness. Of course, romantic young people, when it comes to sunrise and sunset, you will not miss the sunrise or sunset. ”

"It's amazing what you've done in the depths of the earth!" Haige boasted heartily, saying that it would not be an exaggeration to call Wedel "the creator of the depths of the earth."

Wedel was full of amazement and sighed: "If you don't get the super metal materials that the Light of Salvation urgently needs, no matter how much effort you put in here, it will only be in vain. It's like a lot of zeros hanging after 1, if 1 doesn't exist, a million zeros are no different from one zero. ”

Wedel granted Hai Ge's wish to visit Woxiang Mountain, and they boarded a cross-star flying machine with full vision.

This type of aircraft, powered by light energy, is designed for short-distance patrols. Its chassis is in the shape of a regular cross, and the passenger compartment on it sits exactly two passengers side by side.

The aircraft uses a fully transparent closed glass cover, and the glass is so clean that there is not even a speck of dust that obstructs the view, so passengers can have a clear view of the scenery from the seats no matter which direction. The magical glass cover, which also has a magnifying function, can be used as a telescope, and Haige praises it as a veritable all-field aircraft!

Because the plasma stream liquid from which the Earth's engine is started is transported into underground pipes, there is no danger in approaching it from the sky through an electromagnetic barrier.

When the aircraft flew over Woxiang Mountain and hovered to a halt, Hai Ge exclaimed uncontrollably, "Oh my God, this place is so wonderful!" ”

It's no wonder he can't control his excitement, although the Lying Elephant Mountain is not as majestic as those famous mountains and rivers on the earth, it is only equivalent to a medium-sized mountain range, when looking down condescendingly, you can find that its overall shape is a lying elephant with a long trunk stretched out its limbs, no wonder it is named Lying Elephant Mountain!

On the other side of Woxiang Mountain, there was an incredible scene, Hai Ge spread out in front of his eyes a boundless ocean, the sea surface was sparkling, the blue was deep and clear, and it was so beautiful that it seemed that the painter used a palette to make it.

There are no boats stirring up the waves in the sea, but from time to time you can see large sea creatures flying under the surface like shuttles.

No wonder you smell the smell of damp seawater, and the sea really exists here!

Speaking of Lying Elephant Mountain, it seems to be an elephant sleeping soundly, the upturned trunk is the area densely covered with white pot antennas, and the elephant's head behind the trunk is a circular building, and it is still impossible to see whether the building material is glass or metal, in short, it emits a black-brown light in the sun.

Haige couldn't see the building from the flat ground because it had surrounded a large field of greenery mixed with flowers of different colors, and those plants were like a wall separating the building from the earth's engine, which occupies the largest area on the elephant's back. In the middle of the two, the plant belt resembles a beautiful green necklace, neatly worn around the neck of an elephant, and it seems that the heavens have awarded it a laurel wreath in recognition of its merits.

It was not only the ocean that caused Hai Ge to exclaim, but also the earth starting the engine, which was like a giant crab crawling on the elephant's back, and a total of eight long crab legs made of steel extended on the left and right, giving people the feeling that it was not built on the Lying Elephant Mountain, but wrapped the mountain with eight giant legs, and flew here from a distant and mysterious distance.

The giant-like pillars that Hai Ge saw at a glance on the ground were actually the heat pipes of the plasma fusion engine, and the heat energy discharged was converted by the plasma optical flow generator and dispersed into the atmosphere to maintain a moderate temperature in nature.

Weedel also told Haige that the heat emitted by the engine was enough to be used up in the entire underground plant kingdom, so it was stored in the energy warehouse on the elephant's head in case of emergency.

"That circular building turned out to be an energy storage warehouse, I hope the AI control system can fully ensure the safety of the warehouse, otherwise in case of an explosion...... Hai Ge closed his eyes, not daring to imagine further.

"Mr. Wedel," he had a new question.

"Ask, kid, I'll be happy to answer for you." Wedell said with a smile.

Hai Ge asked, "Since the earth's engine can produce such a huge amount of heat and light energy, and convert some of the energy into electricity, the supply of nuclear fuel required for it is estimated to be amazing, right?" Where do you get all this fuel? ”

Wedel was silent for a moment, then asked rhetorically, "Do you remember the empty continental shelf you walked into when you first entered the Shadow Illusion?" ”

"Oh, of course I do!" Hai Ge was taken aback, and he didn't know what the purpose of the continental shelf in the East China Sea where there were no sea creatures in the Vedelti East Sea at this time.

"Uranium ore is indispensable if you want to get enough fuel through nuclear fission," Weedel said. The abundance of this mineral deposit in the center of the earth is unimaginable to people on the ground. According to the data so far, the total reserves of uranium ore in the crust are about 1.5 million tons, and the number in the inner world is three times that number. This is good news, but the bad news is ......"

At this point, Wedel paused, and Hai Ge was anxious, and hurriedly asked, "There is bad news?" So what? ”

"If uranium mining is carried out on a large scale without consequence, it is likely to cause a change in the structure of the Earth's core, so that the light of salvation will not only not save the planet, but may also lead to its early demise," Wedel said. Therefore, we urgently changed our plan and decided to use the earth's marine power to supplement the shortage of uranium mines with the power resources of natural reserves in the depths of the ocean. ”

"You...... You don't mean to move all the seabed on the surface of the earth to the core layer, do you? "Hai Ge's tongue is a little hard to wrap around.

Weedel smiled: "It's too exaggerated to move all of them, I can only say about half of them." We mainly use reefs and gravel in the seawater. ”

"This ......" Haige couldn't believe Wedel's words again, how could reefs and gravel replace uranium ore for nuclear fusion reactions?

Seeing his bewildered face, Wedel explained: "Using things like reefs as fuel, called heavy element fusion, is a supplement to nuclear fusion, but it requires more complex equipment and increased labor intensity. Fortunately, the underground plant kingdom has plenty of robot manpower that can get the stone fuel we need in a very short time. ”
