Neptune Warlord: My Fate Is up to Me.

As a senior otaku, the protagonist plays with an artificial girl one day and is about to enter the game. Unexpectedly, he travels to a different world, the Xuanhuang Continent, and the Shenlong Empire. Among the eight great families, the Northwest Chu family controls the Silver Armored Cloud Dragon Army. I thought I could do whatever I wanted after traveling through time, but I didn't expect that the system was incomplete. I accidentally activated the lust among the seven deadly sins. Therefore, if I wanted to become stronger in the early stage, I could only keep attacking the opposite sex, gain their favorability, and then copy some special skills and attributes from them. The protagonist, who has been a young otaku all his life, was forced to become the first Sea King in the new world by this incomplete system, but the ultimate goal of the system is to evolve into the final Great Demon King system. Therefore, the protagonist will then fight wits and courage with other reincarnated persons with systems, and continue to develop their respective forces in this new world. And through constant growth with the opposite sex, the protagonist gradually established his own power and became the most beautiful warlord in that magical world who can never be imitated or surpassed by others!
