Feng Yuan traveled to the Three Kingdoms with an iron box in his arms. The iron box is not a weapon, but a quantum device - it can analyze the underlying logic of this world. This world is more than swords and intrigue. The soul is an electromagnetic wave, a series of formulas projected from a five-dimensional entity into a four-dimensional space. The seven realms of practice - keeping still, contemplating recovery, understanding the mind, seeing one's nature, knowing one's fate, following one's heart, and being in harmony with the Tao - are not martial arts, but the ability to control the quantum state. The iron box can tell which state everyone is in, including himself. There is an inhuman existence beside Feng Yuan, Xingkai - a quantum humanoid weapon that always appears to be a small level higher than his opponents. No one knows his true upper limit. The name is taken from Zhuangzi's "Equality of Things". The heroes of the three teams rushed to invite him to come out. He chose eight hundred men. Because his mother, Shen Wan, left a message, because a girl named Ruoruo was waiting for him at the ferry, because her sleeves were burned and no one was repairing them. Someone planted a flower that does not save people on the top of the ghost mountain, and someone used the 3001st data to write a four-word sentence. The lights are out, but the road remains.
Quantum enters history, and the love is deep and will last forever.
