Chapter 191: RC Cells_2

This is a counterfeit item procured with the help of Ma Donghe, intended to replace the genuine one.

As for the blood samples inside, naturally, they were drawn from his group of brothers.

The only flaw was that the handwriting was slightly different.

However, under normal circumstances, as long as nothing abnormal was exposed, no one would pay such close attention.

Just as Fang Cheng carefully placed the two counterfeits into the tray.

Suddenly, a series of footsteps came from outside the laboratory.

Followed by a "beep" sound.

It seemed like someone had returned and was swiping their card to open the door.

Fang Cheng quickly put all the open storage boxes back in place, then flipped and jumped out of the window.

Click.

With the sound of the access control opening, a person quietly walked in.

Fang Cheng did not immediately leave but instead lay on the outside of the window sill, secretly observing who had returned to the laboratory.
