Signed into the Underworld, I Became the Interstellar Yama

In the interstellar calendar year 217 of parallel time and space, the earth and the rifts of other worlds intersect, supernatural events occur frequently, and superpowers quietly rise. On the surface, the world maintains the prosperity of technological cities, but secretly the "Spiritual Cardinal Guild" controls the supernatural forces. There are academies of supernatural powers in major cities to cultivate awakened people. The protagonist Jiang Shiyi is an orphan who relies on hacking skills to get into the black market on the Internet. He accidentally signs in at an abandoned subway station and awakens the "Nether World Travel" ability, and is bound to the "Underworld Check-in System" - if you sign in at a supernatural place every day, you can receive strange rewards from the underworld: Po Meng's lipstick, the judge's pen, the ghost's sunglasses... He is thick-skinned, poor-tongued and bold, as stubborn as a donkey, but his IQ crushes everyone. While he relied on the system to make a fortune and kept his money like his life, he was involved in a supernatural conspiracy. He was a loner but had a sense of justice. Under the neon lights of the future city, the magic academy system is intertwined with the supernatural guild, and the campus, underground black market, and ghost realm travel in parallel. Wearing sunglasses, he stepped on the boundary between yin and yang, saying "This order will cost more," and beat the evil ghost into a QR code behind his back.
