It was an underground military base in the Northwest of the Asian Alliance. It was highly confidential, and even the military rarely knew of its existence.
There was a special cell here, and only the most dangerous criminals were qualified to be locked up in it!
In the empty cell, there was only one bright lamp hanging from the ceiling, emitting a white light that made people feel upset.
It was a special lamp made of a special transparent mineral powder and then filled with a special gas. It glowed through two metal wires as thick as hair.
The reason why it took so much effort was to ensure that the foreign cultivators who were locked up could not find any useful tools, which would form an unnecessary security risk.
The level of defense here was extremely high, and it could be said that not even water could pass through.
Once inside, unless the door was unlocked from the outside, the prisoners locked inside would never be able to escape from the inside.
