Zheng Ren knew that since yesterday, he had been in a state of nervousness and excitement. Coupled with the freezing rain on the road at night, he had been in a state of panic when he came to Nanchuan Town. Even a strong man could not endure it.

Su Yun was still considered pretty good. The other students had long exhausted all their energy. When they could not take it anymore, they found a place to take a nap. After waking up, they got up to continue the search and rescue mission.

"If you're tired then you should sleep for a while. Anyway, we just need a small incision for the surgery not larger than a pinkie. We don't need you." Zheng Ren struggled to spot Zhao Yunlong's figure in the rain.
