Chapter 261: Need to Conduct an Experiment with Ye Qing

"Jiang Yan, what are you thinking about?" Ye Qing saw Jiang Yan staring fixedly at a certain spot and couldn't help but ask.

Jiang Yan pulled herself out of her thoughts and shook her head, "Nothing."

Now clearly isn't the time for grief and sorrow.

They are currently located on the 101st underground level, even if a collapse won't happen again soon, what about oxygen?

When the facilities were intact, there should have been a ventilation system delivering fresh air to the shelters and tunnels.

But now, it's obvious that the ventilation system has likely been damaged and shut down.

Thinking this, she glanced at everyone and said, "Everyone, take some time to rest and replenish your strength, we need to hurry and leave this place soon."

"Leave this place?" Su Dai, who had just finished cleaning Sun Jingtao's wounds, was startled and asked, "But Jiang Yan, where can we go?"

Kong Wu, Qin Lang, and Ye Qing obviously realized what she meant.
