After losing his parents in a car accident, Ryan immediately caught his fiancee cheating on him with his best friend. In just a few days, he lost everything he loved, so Ryan decided to buy a house in the mountains to process all those events. However, something happened before he could even enter his new home: the end of the world. Monsters began to appear out of nowhere, and dragons began to dominate the skies. After losing everything, Ryan, who had lost his sense of reality, found new goals with the world in that state: survive and get stronger. Dungeons, classes, monsters, skills, the chance to obtain the DNA of other monsters... Ryan was decided to use them all because he no longer would become a spectator in his own life. Maybe with power, he won’t lose anything anymore. The story, all names, characters, and incidents portrayed in this production are fictitious.

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!
