Idea One

Inside the safehouse in the cave.

Yu Hong sat down, gasping for air as he tried to regain his strength.

He placed the talisman array on the ground, his body drenched in sweat, his eyes also blurred by sweat, barely able to open them.

After resting for a few seconds, he turned his head to glance at Doctor Xu, and seeing that she seemed to be resting with her eyes closed, he reached out on his own to press on the silver talisman array on the door.

After a pause of a few seconds, he released his hand and, upon seeing a black countdown for recovery appear on the surface of the talisman array, he finally breathed a sigh of relief.

It wouldn't take long, just over forty minutes, to completely recover.

"Doctor Xu, are you all right?" Yu Hong finally had a moment to ask.

"....."

There was no response.
