Even he didn't know why, but he suddenly found himself smiling.
Perhaps it was the sudden companionship on a lonely journey, much like Robinson meeting his Friday.
Fearing it was merely a mirage deliberately designed by Designer Ke, Yin hurriedly controlled his character to run towards that silly boy.
With a combined effort of running and flying, Yin rushed over and greeted the boy.
"Hello there, little brother," he said.
Of course, in the game, this was nothing more than him gently charging up, and then his character model emitting a semi-circular arc of white, transparent light.
But what lightly stirred Yin's heart was,
that NPC responded to him.
It too charged up and sent out a gentle circular arc of light from itself, as if answering Yin's "greeting".
This scene also inexplicably made the audience's smiles rise.
They had accompanied Yin through a solitary journey lasting over ten minutes.
