Prequel to Return to Origin: Canglan Destroys Master Immortal

Chen Chumo, an ordinary college student. Occasionally, I went to the antique market with my sister and found a Yin-Yang fish stone. That night, my soul traveled to another world and became the young master of the poor prince's house in Nanliang. He thought he would spend his whole life farming in this feudal dynasty, but he found out that this was still a world of cultivating immortals. The yin and yang fish stone could allow him to travel between the two worlds and bring back items, so—— Modern salt-sugar glass mirrors, fertilizers, cement, antibiotics, and spicy snacks were sold by him as hard currency from other worlds; otherworldly spiritual stone elixirs and spiritual spring exercises were brought back to modern live broadcasts for cash. In modern times, he is the number one "immortal cultivator" on the Internet. He consecrates light and cures diseases with spiritual springs, and was named a grand master. In the other world, he is the chief counselor of the Prince of Nanliang. He engages in infrastructure construction, joins sects, engages in business wars, and makes the devil have no way out. Later, he led the Prince of Nanliang to sweep across the Northern Kingdom and drove the Demon Sect into the desolate land of the Northern Barbarians. He controlled one area per person and maintained the peace of the world. Everyone thought he was the reincarnation of the Eternal Immortal Lord. Only Chen Chumo himself knew: He is just a bad guy from two worlds, and by the way - he became an immortal.
