Go into the Cave

The assistant turned and left the lab, walking to the elevator and opening a door nearby. Behind the door was a staircase, with another space downstairs. As same as the lab floor, there was a hallway with doors on both sides, without any other lab though.

These hallways were also guarded by quite some armed soldiers.

"I need a few men." The assistant went downstairs and said to the soldiers in the hallway. The soldiers glanced at each other. At last, the few soldiers near the stair stepped out and moved toward the man.

The assistant thought for a moment and then said to one of them, "You, go out through the back door and prepare a medium-sized van, then wait inside."

"Yes, sir!" The soldier responded, then turned and walked into the elevator.

"I need more men," The assistant looked at the rest of the soldiers as he shook his head and said. The soldiers glanced at each other again, and five men stepped out.
