I cant remember the start of this novel but I do know some of the events that happened. Its a fairly modern/futuristic setting with a reincarnation. The MC uses current tech to improve his abilities not only in cultivation but also in energy consumption. The mc used nuclear factories as generators and had even started industrializing the dark aide of the moon. He had made his own satellite styled network and had ended up pissing a few countries off because of it. Korea had a terrible invasion of undead and was in ruins, the MC came in and took care of the problem under the condition he got that land for himself, again displeasing lots of people. He saved a few fantasy races like dwarves and even had a super A.I. to maintain his base. Thank you for your help in finding this!! ~PS I'm sorry for any bad grammer or such.
I read a manhwa similar to this, i mean it's the same plot I Am The Sorcerer King, the novel doesn't have a traslation though
I looked around for this visual novel and found a translated one on a couple sights. It was the right name. Thank you very much!!
