In the distant fantasy world, the mutant human race has occupied this land for many years. They are divided into two tribes, the toilet man and the camera man, brutally destroying cities and bringing endless suffering to the residents. However, in this dark moment, an ancient prophecy was awakened. They say that when the Holy Son is born, divine power will come, and he possesses the power to bestow a brave bonus on weapons. This holy son is destined to lead the people to reclaim the city occupied by toilet people and photographers, and restore peace and prosperity. Players will play the legendary Son and embark on their battle journey. Players need to synthesize different weapons to provide powerful combat power to the small soldiers. As the small soldiers upgrade and their weapon levels increase, they will become increasingly powerful and able to face even more challenging challenges.
