"Do me a favor."
"If it's about Little Dot, save your breath. Yanyan has just accepted me, I don't want to mess it up because of you again. Besides, Little Dot is being raised very well by Zi Qi, far better than you ever did."
"...It's not about that." Jian tore off the mask from his face, "And another thing! That's my biological son, I've lived for tens of millions of years and he's the only child I have! I haven't even held him once!"
"I have held him. The kid is quite well-behaved, especially understanding, and his invisibility technique is superb."
"My head must've been caught in a door to have come to you," said Jian as he turned to leave.
Welly did not urge him to stay.
Jian walked a few steps, then turned around again, "I'm going to kill the Demon God. If I return to the Origin Realm, take good care of Little Dot."
