I recommend "Public Enemy of the Villain" and "The Legend of Armament Cultivation in the Other World". Both are novels in which the main character transmigrated to the continent of another world with memories of his previous life. The main character was invincible in that era. He had an accident and transmigrated to the other world many years later, beginning his adventure in the other world. I hope you like this fairy's recommendation. Muah~😘
