727 Unless...

Dr. Feng's daily routine did not change much aside from the addition of Luan in between his busy schedule. 

But instead of complaining, he was very interested in tackling the problem in front of him. Luan's presence was akin to a breath of fresh air in his monotone life, sparking a fighting spirit within him which he thought had long been doused by years of constant work around the clock.

Luan kept to his words. He mainly stayed in the corner of the room, gazing out at the distance with a wistful look on his face. Sometimes, when Dr. Feng was too immersed in his work, he would sneak a few glances without letting the other party know. 

Within a short few days, he merged perfectly into the environment of Dr. Feng's office and was taken as a new ornament by the other researchers.
