Two days later.
Yi Lin was dressed in a black robe with a pointed hat on her head.
On the podium, white-bearded Ah Deng, holding a small stick, spoke eloquently and spiritedly.
Above Ah Deng's head was a shiny green.
Don't get it wrong.
It was only his name that turned green, nothing else.
After officially becoming a member of the Grand Engineering Institute, Yi Lin's [Reputation] panel showed her reputation with the Grand Engineering Institute advancing from "Neutral" to "Friendly".
So, Ah Deng's name turned green.
He became a green-named friendly NPC.
Yi Lin also rightfully gained a new title.
——[Junior Engineer].
This title could be advanced.
To advance, one had to truly complete the courses and exams at the Grand Engineering Institute, step by step.
The blackboard was covered with dense lines.
"Crystal Patterns" and "Nodes".
Ah Deng was propping up the blackboard hard, fearing that Yi Lin would get distracted, and lectured loudly.
