Han Won, codenamed "Schrödinger", is an interstellar observer from a high-dimensional civilization. Due to an accident, he strayed to the earth and possessed the body of a low-level liar who had just gone bankrupt.
In this strange world where the civilization of immortality and science are intertwined, Han Yuan discovered that he has the talent of "cognitive bias" - he can make 99% of people absolutely believe the lies he made up, and only 1% of the chosen ones can see through the truth. The cost of activating this ability is that every time the scam is successful, you must complete an "interstellar mission", otherwise you will lose all abilities.
In order to raise money for traveling home, Han Won began to conduct elaborate scams in this world. He deceived the head of the cultivating sect, deceived the CEO of the technology group, and even made the dignitaries of the entire imperial capital willingly offer spiritual stones and banknotes. However, he encountered the biggest obstacle - Su Qingxue, the saint of Jiuyou Sect, the 1% chosen one who can see through all his lies.
On the surface, Su Qingxue is a cold and pure fairy saint, but secretly she is a vicious female partner who controls the "Tianji Pavilion" intelligence organization. She took a fancy to Han Yuan's talent for deception and wanted to take him for her own use, while Han Yuan just wanted to escape from this perverted woman.
A battle of wisdom and scheming, a game of lies and truth, Han Won will find his way home between the interstellar mission and the earth's scam
