Fusing with Zhongli, I Built Liyue Harbor in Demon Slayer from the Start

After transmigrating into the world of Demon Slayer, Lin Yaoyang fused with Zhongli's template. By imitating Zhongli's behavior and killing demons, he can increase his template synchronization. 【Ding! Host's synchronization has reached 5%. Ability unlocked: Elemental Infusion】 【Ding! Host's synchronization has reached 10%. Passive skill unlocked: Dominus Lapidis】 From then on, a paradise called Liyue Harbor appeared in the world of Demon Slayer. And it gained a powerful Demon Slayer: Lin Yaoyang. Muzan Kibutsuji was terrified. What kind of monster is this? Why does he have the power of a demon, yet can walk freely in the sunlight? Akaza questioned everything he knew. How can this man's physical abilities be even stronger than mine? Kagaya Ubuyashiki: In a century of unprecedented change, Cang Zhen, your power will be key to fighting the demons. Tengen Uzui: What a flashy young man, even flashier than me.
