Super Invincible Battleship
Chapter 620

Chapter 620: Chapter 275 Official Launch Chapter 620: Chapter 275 Official Launch At 9:30 p.m. the following night, Yan Fei set out again, using the Drone to traverse underground. Last night, Yan Fei had used shockwaves to cut three faces of the rock below, and there were three more faces that needed to be cut. Only when all six faces of the rock were cut could the rocks in the Underground Space be transported away.

Guided by the Quantum Radar, Yan Fei controlled the Drone to make its underground traversal, arriving at the site corresponding to the first vertical face he had cut the day before, then activated the shockwave according to the previously set parameters, cutting this corresponding face away from the surrounding rock. With this, the four faces of the central rock were completely separated from the surrounding rock, with only the top and bottom still connected to the surrounding rock.

Then, the Drone once again traversed underground, coming to one of the upward-facing faces of the rock. This location was 100 meters deep from the surface and would become the roof of the underground super nuclear power plant in the future. However, when setting the firing parameters, Yan Fei did not let the shockwaves sweep directly across as before to completely separate the rock from the top. Instead, he calculated the correct angle, shape, and length of emission before finally discharging the shockwave.

In the future, this will be a massive Underground Space, stretching 700 meters in length, 250 meters in width, and 60 meters in height. From a mechanical standpoint, such an enormous hollow Space is extremely dangerous, and a collapse is very possible. Even if the surrounding material is a very hard rock, even comparable to steel, a collapse could not be entirely prevented.

To avoid such a disaster, this vast hollow Space had to keep some large rocks to act as support columns, to prop up the rock above, preventing it from collapsing downward. These rocks were already incredibly hard, and Yan Fei had calculated the distribution of the support columns to ensure they would be evenly stressed. With these support columns, the huge Underground Space would be very safe, with no risk of collapse. Thus, when cutting the top and bottom faces of the rock, Yan Fei would not cut them completely but would leave some areas untouched–these areas were where the support columns would be.

Because of this, the firing angle and power of the shockwaves had to be extremely precise, causing the Energy Points to be consumed dramatically. So, this time the emission of shockwaves was completely different from before, just as the top rock was being cut, the Drone Energy Points were almost exhausted. However, after this emission of shockwaves, aside from leaving behind twenty-four massive circular stone columns still connected, the huge rock was finally separated from the layer above it.

On the third night at 9 p.m., Yan Fei continued the construction, but this time he did not go underground himself, instead standing on the distant ground above and remotely controlling the operation. He did not control the Drone to cut the final connecting bottom face of the rock but instead cut the middle rock mass according to the requirements of the Auxiliary Brain's Design Drawing. After several continuous shockwave emissions, a huge rock was finally completely cut out.

The Drone then nudged the giant rock forward, incorporating it into the Universal Space, and then Yan Fei pointed with his hand from above ground, opening another passageway of the Universal Space, transferring the huge rock from 100 meters below up to the distant ground above.

The first rock was cut and moved away, creating a space underground. With this Space, the movement of the Drone became very simple, no longer needing to traverse underground like before. And with room to maneuver, the Drone's efficiency in cutting rocks also increased. By the time midnight arrived, the Drone Energy Points were entirely depleted, and an underground square Space with a side length of 60 meters had appeared. The rocks from this original space had been moved by Yan Fei to the surface above and were then piled together.

During the operations underground, the twenty-four massive rectangular stone columns slowly took shape. It was due to the need to consider these twenty-four columns that Yan Fei's digging speed was greatly reduced. However, these twenty-four columns were very important; with their support, the stability of the super nuclear power station below could be ensured. These rocks were extremely sturdy, comparable to steel, and since they were originally connected as one, their support would make the underground nuclear power station as stable as Mount Tai.

In the following days, Yan Fei would continue to dig underground every night. Ten days later, he finally excavated a huge Underground Space 700 meters in length, 250 meters in width, and 60 meters in depth, 100 meters below the surface. This Underground Space was completely in accordance with the design of the Auxiliary Brain, even the twenty-four support stone columns matched the design exactly.

Furthermore, Yan Fei had taken time to dig an Underground tunnel. This tunnel was not large, intended for Yan Fei to enter the underground nuclear power plant in the future. This tunnel also served as the sole conduit for conducting the electricity from the nuclear power plant, extending 3 kilometers south, rising to the surface from a secret location. Above ground was a room, perfectly concealing this Underground tunnel. Then all the electricity would be transported from this room to a substation, for use in the operations and production on Misty Island.

As for the several large holes that Yan Fei had previously dug leading underground, they had been filled by Yan Fei but with some small holes left, serving as ventilation ducts for the underground super nuclear power plant and the outside world.
