After Traveling Ten Seconds and Dying, I Assist the First Emperor in the Underworld

Li An, a history college student, traveled through the late Qin Dynasty and awakened the most powerful auxiliary system. Resolutely bind the lord Ying Zheng, the eternal emperor, and bind the bond of 100% trust, life and death, and the invincible monarch and ministers! I thought that embracing the eternal golden thigh would help the First Emperor change his destiny and prevent the Second Emperor of Qin from perishing! Unexpectedly, the day of the binding was the day when the First Emperor died in Sand Dune! Li An traveled through time for only ten seconds and was buried directly on the spot, dying together with Ying Zheng! Once they opened their eyes, the world came to an end, and they both fell into the eternal underworld where heroic spirits reside forever and transcend reincarnation. The style of the Qin and Han Dynasties, the Three Kingdoms, the prosperous Sui and Tang Dynasties, the literary giants of the Song Dynasty, the majestic Ming Dynasty... Thousands of Chinese heroes, overcoming thousands of years of separation, gathered in the underworld. No more dynasty grudges, and they all respected the First Emperor as their master! At that time, in the underworld, the underworld was corrupt and dictatorial, the Asura demons were raging, and the Western gods were divided and hegemonic. They regarded the Chinese heroes as ant wild souls and oppressed and slaughtered them wantonly! All the unfinished ambitions in the human world will be fulfilled in the underworld! Ying Zheng is the emperor of eternity, in charge of the universe and to subdue the gods! Li An seeks sage for eternity, strategizes and determines the world! Bai Qi, Han Xin, Huo Qubing, Li Jing, and Yue Fei chased demons and gods, and conquered the outside world! Zhang Liang, Xiao He, Zhuge Liang, Guo Jia, and Liu Bowen planned for eternity to stabilize the country! From two people opening up wasteland and building a city in the wild, to unifying the Yin Land of the East and conquering the Divine Court of All Nations in the West! Kill Yama, pacify Shura, defeat all gods! Reshape the order of the underworld and create the eternal Chinese dynasty! The Chinese culture in the world is endless, the Chinese heroes in the underworld live forever, and in all the heavens throughout the ages, I, the Chinese, are the only one!
