In a luxurious villa, there is advanced medical equipment unknown to outsiders.
Zhuo Yi and Si Ye, dressed in antibacterial suits, wearing white masks, white hats, and white gloves, stood in a sterile white sealed room.
In front of them, was a glass vessel composed of two hemispheres.
Below, the lower hemisphere contained ice cubes, and atop the ice cubes was something the size of an adult's fist, powerfully pulsating.
It was a heart, with two slender transparent tubes inserted into its ends, fresh blood constantly flowing into the heart through one tube, and out through another.
The two tubes passed through the upper hemisphere and were connected to a machine with a complex and bizarre shape, its screen flickering with indecipherable codes.
The machine itself had many buttons and red indicator lights.
As long as the largest indicator light on the machine didn't extinguish, the heart could keep beating indefinitely without failing.
