A mind to harm is sometimes needed, and a mind to guard is always necessary.
Some people in this world are bad enough to shine a flashlight into Captain Jack's eyes as kids, donate indigestion tablets to poor mountain areas as adults, equip nursing home walking sticks with caster wheels when they're old, and swallow a bunch of popcorn kernels just before dying as a trick for their cremation to pop.
Living in such a society, caution and prudence are crucial.
Especially since this matter concerns Xue Jian's own interests, he must be on his guard.
Maybe the hallway surveillance camera caught it, but during the process of Lin Li following Guo Zhun to escort the exam answer sheets, Xue Jian didn't make a move; he just watched Lin Li with an extremely complex expression.
It was a complexity beyond human description. They say the eyes are the windows to the soul, but Xue Jian seemed to have crashed, probably needing a reboot with a Mac.
