Gods and Demons Warring States: I Am an Undercover Agent in Da Qin

At the end of the God-conferring Tribulation, the leader of Tongtian Religion returned to heaven and earth, and everything was silent. One hundred and twenty-nine thousand six hundred years ago, the world entered the chaotic times of the Warring States Period when hundreds of schools of thought contended. The gods quietly revived with the help of incense. Qin Yuan, an ordinary time traveler, is fortunate to be able to deduce all kinds of magic by consuming "Yuan Qi". After reaching the extreme level, he can even obtain various magical powers. In this era when gods and demons have returned, how can we compete with them? Yuan Qi! Qin Yuan dealt with multiple forces. From "craftsman" to "prime minister", from "ancient Shu spy" to "human emperor orthodoxy", from "Mo family ranger" to "a giant of the generation". . . As his identity continued to change, the number of "Yuan Qi" he collected increased day by day, and he gradually embarked on the road to invincibility.
