Long Fei went to every corner of the lab to look for anything that he might miss. Once he was sure that he did not miss anything, he then walked towards the door.
As he walked past that professor, Long Fei stopped briefly and noticed the way that man has been watching him.
"Professor Chen, don't worry, I will take care of your family," Long Fei said.
Although the old man was unable to move, he could see, hear, think and feel things around him. It would not be difficult for that man to understand what he was trying to say.
Professor Chen's expression changed. Hatred filled his eyes. If only he could move, he would definitely attack Long Fei on the spot.
Long Fei's lips turned into a sneer. "After all, it would be rude not to return the favor." Long Fei shifted his gaze to meet Professor Chen's briefly. Then, he walked out and closed the door behind him.
As soon as he stepped out, a guard in his black uniform walked over.
