Yu Liang was not certain what that guy had actually done, but judging from the results...
Yu Liang created Yu Liang.
A Yu Liang with the writer Yu Liang's account, a Yu Liang with Yu Liang's memories (except for those three days), a Yu Liang that restarted in a complete state.
The Yu Liang who appeared three days later might not have been Yu Liang, but to this Copy, he was Yu Liang, and now Yu Liang is also willing to do something a real Yu Liang should do.
With Yu Liang's abilities, Yu Liang's personality, Yu Liang's memories—doesn't that make him Yu Liang?

Some of the previous doubts were also connected together.
Killing him was meaningless.
