A huge space had been hollowed out in the underground of the North Pole.
This used to be the most important place in the Jiangli Empire. Jiang Li had conducted various experiments here, especially the construction of the ultimate spaceship.
So far, Jiang Li had built four spaceships in total.
One of them was smaller and had already been completed. The 2nd, 3rd, and 4th ships were not completed.
However, these were all experimental products, all prepared to build the ultimate spaceship.
However, even if it was an experimental product, it still amazed Shen lang because it was too huge.
Each spaceship covered an area of more than a few square kilometers. It was like a small moving city.
Not only that, the outer shell of each spaceship was extremely advanced and was divided into three layers.
