Thus, Lin Yifan and his team hurriedly used Qinggong to jump down; they slipped into the enemy's interior before the enemy arrived.
The steel plate above the launch shaft must be movable, or able to be opened outward, since whenever the arms organization wanted to launch a large missile, the grassy area above would definitely change, revealing the entrance to the launch shaft.
It was precisely because of this that the steel plate covering the shaft entrance was made of thinner, tough steel; because thick steel plates are too hard to move, the arms organization would not engage in such thankless, labor-intensive tasks.
However, it was this design that gave Lin Yifan and his team an opportunity to exploit.
Actually, one can't blame them, as normally such tough steel plates are impossible to break through; it's just their bad luck that they now faced extraordinary people.
