The Prince at the Beginning, Guarding the Border for Fifteen Years

Li Yuanying traveled to the Tang Dynasty and became the 22nd prince of the great ancestor Li Yuan. When he was only six years old, he was demoted to Yanmen Pass by Li Yuan and punished to guard it for life. Thanks to the Human Emperor sign-in system, you can become stronger by signing in every day "Hey! Congratulations to the host on the first day of signing in. I hereby reward the bravery of Yu, unparalleled throughout the ages, and the inheritance of King Xiang Yu of Chu." "Hey! Congratulations to the host for signing in for the second day. I hereby reward you with the horse Kiyun Wuzui, a green and white horse with black hair, and the mount of King Xiang Yu of Chu." "Hey! Congratulations to the host for signing in on the third day. I hereby reward you with a tiger-headed dragon halberd, a black-gold armor, and the weapons and armor of King Xiang Yu of Chu." ... "Dip! Congratulations to the host for signing in on the 22nd day. I hereby reward the inheritance of the famous Western Han Dynasty general Huo Qubing." Li Yuanying silently signed for fifteen years with the idea that he would not leave Yanmen Pass until he was invincible. Finally, Li Shimin launched the Xuanwumen Revolution, and Li Yuan had no choice but to ask for help from the twenty-second prince Li Yuanying who was far away in Yanmen...
