Prehistoric: Fusang Sign in to Prove the Saint

Su Chen traveled through the prehistoric times and became the Little Golden Crow in Tanggu, and was imprisoned by the Emperor of Heaven in Fusang for thousands of years. When he was on the verge of loneliness, he activated the sign-in system, took root in the Fusang Sacred Tree and signed in, learned the true fire of the sun, broke through the emperor's ban, counterattacked to suppress the demon clan, and embarked on the invincible road to sainthood.
