[System + Invincible + Funny and Nonsensical + Occasionally Serious] Sikong traveled through different worlds, obtained the system, and worked hard to cultivate to the highest level. Become the most powerful person in the holy realm, the body of eternal life. However, the old system was retired and a new small system came into being.
