The Outcast: My Three Corpses, Zhang Zhiwei!

The prelude is too long; I haven't seen the title in over 30 chapters.

Is the main character always this weak? When will he get stronger?

It's quite interesting, with over 40 chapters, and it's above average for a one-person fanfiction. The downsides are that it's a bit of a riddle, and there's no room for improvement. The cultivation technique is from the Three Demon Sect, but I didn't see any content about cultivating life force, so let's assume it doesn't exist.

He was doing well at the company, and then suddenly he defected.

Based on the current plot, Bi Youlong is very likely to be Qu Tong's man, or at least have a cooperative relationship with him. It would be better to follow Huang Boren than to follow Bi Youlong, right?

I've read up to chapter 34 so far and it seems alright.

The pace is too fast; soon there will be nothing left to write.

The author could consider writing a spy film.

Overall, it's quite good, a rare example of a fanfiction that focuses on plot rather than cultivation. However, the title is a letdown; it easily leads readers to believe it's one of those mindless, pretentious stories where the protagonist has a cheat ability, creates a character like Zhang Zhiwei, and then goes on to dominate the world and build a harem. I suggest the author change the title.
