I'm a Kindhearted Landlord, Not a Nuclear Landlord, Hey!

A practice project! I'm a newbie, and this is my first time. Please point out any problems. Thank you. The apocalypse brings ruin, all life falls into chaos, and the ruined city becomes a hellscape of corpses. Ye Zhi commands an invincible skyscraper, impervious to all calamities, and awakens the Doomsday Landlord System. He takes in survivors to build a stronghold, forges his edge with crystal cores, and wields the rare power of lightning as he climbs step by step to the summit. He appears detached and calm, but deep down, his heart is set on slaughter. He wipes out treacherous wolves and stands against the endless tides of the undead. He uncovers the truth that humanity is being kept in captivity and defies the shackles of the divine realms beyond. Amid the chaos of a troubled age, I hold my ground in my towering building, becoming the supreme, invincible landlord of the apocalypse.
