As he looked at it, as expected, with the four drops of blood leaking out, the patient who had lost consciousness and stopped breathing, slowly heaved and started breathing again. Even though she didn't wake up immediately, it was clear that she wasn't in the state that was about to die.

"Heavens, just a few drops of blood in a simple manner, yet it's already effective?" Everyone released a low cry.

The family members of the patient were also surprised. They never expected that Xiao Yi, who simply released four drops of blood, actually had the effect. It was like seeing the dawn in the dark.

Qin Guangming saw that the patient's condition had improved, but he once again began to cry. This time, he cried with the utmost joy after the crisis.

The two first aid doctors were the most surprised.

The time for first aid between the two of them was not short, and there were more similar cases. In the past, this ventilation surgery was done a lot. Although the patient suffered some pain, at least it could save their life. Some unlucky people couldn't be saved even if the trachea was cut.
