The water was cold. When Chen Jin tested the water temperature with his fingers, he knew that there was no way he could enter the water with his current level of cultivation.
Feeling helpless, Chen Jin could only go to the base at Haierfa again.
Due to the multiple breakouts of interstellar war, the base was mostly producing interstellar warships, and the submarines had not been updated for a long time. Although it was a relatively outdated product, it was still far ahead of the submarines on Earth from the same time. Without thinking too much, Chen Jin collected two or three submarines into his storage ring and returned to the pool.
He put the submarine in the pool and boarded it with the robots. The cabin hatch was closed and the submarine sank into the depths of the water.
