Originally, it resembled a bony fish, with a large head and a small body. After modification, cargo holds were added to its sides. Its long axis is approximately 45 meters, its empty weight is approximately 1,200 tons, and its maximum load capacity is 1,800 tons.

Although the maximum load seems high, it is difficult to actually reach it. After all, when the load exceeds 800 tons, she has to use external buoyancy tanks. The shipping cost will increase several times, so it is better to make more trips.

Soon, several warning bells were heard from outside through the not-so-thick shell of the submarine.

The internal pressure-resistant, watertight gate at Exit 22, driven by a massive robotic arm, slowly closed along a sliding track on the ground. When the outside noise faded completely, the deep, ethereal sound of mechanical fasteners engaging was transmitted through the metal frame supporting the submersible into the interior of Tranquility V.

Everyone stayed where they were, quietly waiting for the water to fill the entrance and exit. At a certain moment, they clearly felt that Tranquility No. 5 was lifted up by buoyancy and separated from the support frame.

The captain found his position and operated a few times on a circular platform the size of a washbasin, and all the instruments in the entire control cabin began to power on.

A holographic globe composed of green dots appeared above the circular platform. After flashing several times, it gradually turned into the outer outline of the submarine - a slightly curved pipe.

The clarity of Tranquility 5's passive sonar is not very high. Each small dot on the command platform represents an area of ​​3.14 square meters. However, in this safe water area, its accuracy is more than enough.

The sounds of flowing water and bubbles were still occurring. To prevent Tranquility No. 5 from hitting the upper wall of the pipe, the captain ordered the artificial intelligence to slowly reduce the buoyancy of the submarine until it was slightly higher than the density of seawater.

After a while, a few lines of text were connected to the holographic terminal:

[Exit 22 is now open, smooth sailing!]

[Generating route, please wait...]

[Electrical engine self-test completed, automatic navigation confirmed! ]

"Confirmed." The captain pressed two buttons, and soon a faint vibration began to appear at the rear of the Tranquility. The seawater was pushed away by the submersible's top shell, and the small green dot on the command platform began to slowly move.

The water flow in the pipe was very calm. Jiang Ling could see that the newly generated agitated green light spots at the tail of the submarine were gradually spreading outward and decreasing in density in a certain pattern.

Tranquility V basically followed the route calculated by artificial intelligence. It accelerated to two knots before exiting the pipeline, and then accelerated to about 15 knots less than five meters above a flat continental shelf.

Of course, this submersible had no windows, and Jiang Ling was completely unaware of the above events. She simply knew that she was leaving a habitat. Within the sphere with a radius of two kilometers, centered around her, the density of organisms quickly dropped to a minimum.

The dark seabed gradually became silent.
