Creak ~~ boom ~~
One of the load-bearing pillars broke, and the entire underground castle was on the verge of collapse.
Li xiaonian didn't have time to think. He took out a figurine-like cosmic battleship from his bag and threw it into the air."Shadow, unseal."
Weng ~~~
An invisible force swept through the entire underground Castle. At the same time, a black spaceship made of special metal appeared in the sky above the underground Castle.
The appearance of the spaceship filled up the entire underground Castle, and even squeezed some of the space around it.
Dozens of load-bearing supports were inserted into the ground.
At this point, the shadow had transformed into the roof of the underground Castle, supporting the surroundings and preventing the underground Castle from collapsing.
The shadow was 3265 meters long, 420 meters wide, and 128 meters tall.
