A loud siren suddenly came from the base before Zi Yi could answer him.
Everyone was startled.
"What's the matter?"
"Did something happen?"
"Did someone barge into the base?"
"Is something happening?"
…
As everyone speculated, Zi Yi turned and headed to the main control room. Runge quickly followed behind her.
After the other people caught on, they immediately followed behind them.
Everyone kept going until they reached the outside of the main control room.
The moment Zi Yi entered the main control room, the rest of them found themselves blocked off by an invisible barrier.
Runge shouted as he stood outside, "Zi Yi!"
When Zi Yi heard him shouting, she turned to look at him. After thinking briefly, she nodded to Runge. Runge proceeded to enter the room as well.
The others wanted to enter as well, but it was futile.
Zi Yi and Runge entered the main control room together.
