The game invaded, and I became the uncle of someone else in another world!

[Traditional writing style, ensemble cast, love triangle, multiple female leads, protagonist is clueless, flashbacks]
Zhou Wan, who traveled back twenty years, always thought she was a transmigrator, never expecting that her original body had been a vegetable all along!
Having died in another world, he returned to this body and was surprised to find that he could still use the extraordinary powers from that other world!
This time he's going to become even stronger!
Looking at his malnourished niece who was struggling to care for him, Zhou Wan vowed to take good care of her. However, to his surprise, the first thing his niece said was, "Uncle, let's rob a bank!"
Sigh... Educating children is a long and arduous task.
"Uncle, do you also have a haughty elf relentlessly pursuing you in another world?"
"I traveled through time in 06. Back then, this thing was called Evangelion."
"Uncle, did you start a harem in another world? How many aunts do I have?"
"My dear niece, in the face of power, even the greatest temptation of beauty is insignificant."
"Uncle, uncle, what's this?"
"Oh, this is called game intrusion, an alien... Wait, how did they get here?!"
