Qing Jiumu, a modern time traveler, unexpectedly picked up the naughty boy Tu Jiu
However, Qing Jiumu was determined to cut off the mortal bond in order to overcome the calamity and ascend. This determination completely ignited Tu Jiuxian's paranoia. In order to keep his master, he did not hesitate to fall into the devil's way, imprisoning Qing Jiumu in the devil's palace, and weaved a cage called "possession" with forced love.
During the years of imprisonment, Qing Jiumu struggled with Tu Jiuxian's fiery and crazy love while secretly advancing the system's tasks; Tu Jiuxian was repeatedly pulled between possessiveness and love for his master, and the relationship between the two became more and more broken and entangled.
The Three Realms War broke out suddenly, and the masters and apprentices who once relied on each other stood in opposing camps. A fateful showdown was inevitable. At the critical moment, Qing Jiumu completed the ultimate mission of the system in order to save Tu Jiuxian, and then returned to the real world.
Thinking that the fate was over, Tu Jiuxian actually broke through the world barrier and followed him across time and space. When the demon king from the world of immortality stepped into the modern city and reunited with Qing Jiumu, who had long returned to ordinary life, this love that spanned the two worlds finally came to a happy ending in the human world.
Intention: No matter what, no matter what you do, you will never abandon each other
