It was because these cells were something that he had already considered as some kind of immortal cells which could neither die and nothing could even harm them.
At least there was nothing that he had not tried and could be said that as a scientist he thought that such destructive conditions that might harm anything.

And seeing his face turning into such a hideous look, the others could not help but feel a bit worried.
That was because, most of the time, this Professor Zhang was someone who was easygoing and there would be rarely any time when he would frown much less have such a look on his face.
