I Am Immortal, but the System Makes Me Commit Suicide and Become Stronger!

[Bitch + funny + seeking death + multiple heroines] My name is Cao Bao, and my nickname is Ah Ma. Good news, I traveled through time and awakened the immortality system. Bad news, this is still a system of seeking death. If you seek death, you will become stronger! From then on, Cao Bao began his painful and happy journey of seeking death and becoming stronger and invincible!
