Douluo Dalu: From the Start, I Inherit Di Qi and Sword Nine Huang

[Multiple heroines + System + transmigration + fan fiction + mostly everyday life]

Zhou Xingyu transmigrates to Douluo Dalu and awakens a Villain System, gaining the Crimson Kamen Rider Decade and Huang Jiu's inheritance. As long as he steals the protagonist's opportunities or defeats him, he can earn rewards.

[Ding! Congratulations, Host. You have obtained the Sword Immortal's Kneel, Two-Sleeve Green Snakes, and a Grand Zi-O Form Ride Card...] But one mission from the System seals his powers for seven years!

[Ding! Congratulations, Host. Mission complete. Your powers have been unsealed.]

Tang San: Zhou Xingyu! Take this, Blue Silver Bind!

Zhou Xingyu: Heh heh heh! I'm unsealed! Tang San, you jailbird, eat this sword, then try taking a kick! (I'm a new writer, so please go easy if you don't like it. Feedback is welcome.)
