After Rebirth, I Relied on the System to Make a Comeback in 87 Days

Jiang Liu spent thirty years in revenge, three years in planning, and the final battle to trample his enemies underfoot. Then a knife was thrust into his back. He didn't even see who it was. After rebirth, he has a system, eighty-seven days, and a bunch of F-level attributes. Enemy Zhou Hao is just the beginning. The man who stabbed him is still in the dark. The clues from his past life all pointed to the same answer, but Jiang Liu decided not to believe the answer in this life. He wanted to pull that person out of the shadows with his own hands. As for the system? Jiang Liu said: Anyone can send it as a gift, as long as it can kill people. Eighty-seven days, 600 attribute points, enough for him to kill from F to A. This time, he wanted to strike back at his enemy's proudest moment. As for the man behind the scenes? Don't worry, you're next.
