Bottom-tier youth He Yu suffers betrayal from his sworn brother and girlfriend, and in a desperate plight discovers a mysterious glass box hiding a miniature cultivation world under his bed. The toothpick he tosses in transforms into a heaven-reaching divine pillar, lobster claws become a great demon's remains, and a battery unexpectedly turns into the "Thunder Origin" fought over by cultivators. Imprisoned in lowliness and hardship in reality, in the eyes of the cultivators inside the box he is instead the boundless upper ancient true god "Desolation". He will use everyday reality debris to harvest magical treasures in the cultivation world, eliminate demons and rescue people, and ultimately feed back into reality, beginning a legendary life.
