Cultivating Harem: A Villain's Path to Immortality [18+] CHVPI

I heard that when people travel to another world, they become super rich second-generation individuals, or at least have someone to rely on. So, why did I, Zhang Wei, become a beggar? Becoming a beggar was not hard enough, why did I lose my vision all of a sudden? Is my life not hard enough?

But I heard there are immortals in this world. Since fate chose to abandon me, I choose to give up my bottom line. I can do anything to become immortal.

Note:
Goal no. 1 : Developing the character towards being evil.
Goal no 2: Creating harem (including 18+ scene)
Goal no 3: Adding some comedy to lighten up the story(will not start until second volume)
