What happens when you transmigrate to Beast World? With the system in hand, the world is for your taking! One day, Su Tang, an intern at the hospital, is struck by a system and transmigrates to Beast World. It’s a wondrous world with winged tigers, fire-spitting birds, and enticing man-eating flowers… Everything in this world leaves Su Tang awestruck!

After the Chief of Winged Tiger Tribe saves Su Tang, she learns how backward this place was. Su Tang is determined to help change the world! Under the system’s guidance, she helps to extract salt, build homes, dig traps, make weapons and store food for winter… And perhaps even save the world while she’s at it!

Humans, once the masters of Earth, were losing their place to the inexplicable phenomena known as Objects.And this is a story about becoming an Object and living worry-free in the Seoul of such a world.

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.
