Li Shimin, I Am the Emperor in the World of Immortality!

Tiance Iron Cavalry is back in troubled times! The majestic power of Zhenguan shines brightly in the heavens! In this life, Li Shimin has to do two things: Protect the immortality of the human race and seek eternal life! Destroy all enemies and let the Emperor's flag of the Tang Dynasty be planted throughout the entire alien world! How can a mere fifty-year reign be worthy of being an emperor for eternity? The moment Li Shimin closed his eyes, the Imperial Seal carried his soul back to another world! Here you can practice Taoism and live forever! But it's also a human purgatory: The human race is killing each other and is in constant civil strife; The ancient monster clan presses the territory and eats the living creatures; Western vampires and angels of light are plundering and wreaking havoc everywhere! The crisis of genocide is imminent! But in the desperate situation, a shocking change happened—— Fang Xuanling, Du Ruhui, Yuchigong, Qin Qiong... All the civil servants and generals of the Tang Dynasty were reincarnated and returned!
