Lin Yeben was a 25-year-old Internet social worker. He died suddenly after staying up late and was struck by lightning. He traveled to the end of the world in 3077 and became a useless person with no powers at the bottom of Qinglong Base. In a world where giant beasts are rampant and the strong are respected, he was accidentally bound to the [Behemoth Symbiosis System] - while others rely on supernatural powers to fight monsters to upgrade, he relied on taming giant beasts as mounts and combat power, and even integrated the giant beasts' abilities to change his fate. As the number and types of giant beasts he controlled increased dramatically, he gradually revealed the truth about his time travel: he was actually deeply bound to the origin of the apocalypse and the ultimate purpose of the system. From a living refugee to the master of giant beasts, he will break the rules of the base, tear apart the conspiracy, use all beasts as soldiers, and strive for the top of the doomsday!
