There are demons in the three realms, who practice through tribulations and become immortals; there are immortals in the upper realm, who are born as immortals, so they need to go through tribulations of suffering before they can be promoted to immortals. The trivial events recorded in the tribulations are called the Immortal Tribulation Book, and the immortal in charge of the tribulations of the immortals is called the Immortal Lord Sijie. Gods are no better than mortals. No matter how much a mortal's life is written, it is nothing more than this. After all, it will never be found in you. But if a noble immortal is given a few more hardships during his calamity, causing him to go through a lot of hardships in the mortal world, he will be in trouble when he comes back, so the immortals also laugh and call him a troublemaker.
This is the story of a troublemaker and her old sweetheart who dominate the three realms.
