I recommend 'The Zi Ying Swordsman of Mount Shu' to you. The male protagonist transmigrated to the world of Mount Shu and wrote down a strategy based on his memories from his previous life. He followed the map, defeated monsters, and seized treasures. He overcame all difficulties and finally became a hot-blooded story of a generation of experts. The male protagonist created a great wish for Emei Sword Sect in order to vent his anger, and he finally realized his dream. I hope you like this fairy's recommendation. Muah ~đ
