It wasn't easy to infiltrate the dungeon in the southwest corner. If the special forces soldiers from the Xueyu unit made a move before figuring out the situation, they would alert the enemy. Even if it was chaotic outside, they couldn't let anything trigger Lardner's defense.
Lardner also knew to lay a trap to see if the Chinese had sent anyone over. Once something happened to him, this cunning pirate leader would definitely move the four scientists away immediately.
Although the dungeon was in the southwest corner, the surroundings were heavily guarded. There were people walking back and forth with guns in the flat-roofed dungeon. Even though these people were being bombarded by mortars, they didn't leave this place.
There were also armed men patrolling outside the dungeon. The entire dungeon was guarded so tightly that not even a fly could enter.
