Ling Feng (modern name), became the deposed prince Ouyang Lingfeng after time travel. The original owner was unjustly deposed because of his cowardice and incompetence. Ling Feng possesses top SWAT skills: fighting, shooting (needs to adapt to cold weapons), tactical planning, investigation and counter-investigation, crisis management, extremely strong psychological quality, familiar with human body weaknesses, possessing certain knowledge of first aid and wilderness survival, and possesses modern thinking and values: equality, efficiency, chain of evidence concepts, etc.
Era background: The Xixia Kingdom is an imaginary ancient dynasty. Its national strength is acceptable but it suffers from internal and external troubles (possible problems such as powerful ministers, foreign enemies, vassal kings, disasters and famines, etc.).
Crossing node: The original owner has just been deposed and is imprisoned in a remote palace or mansion. He is in a difficult situation (being monitored, withheld from expenses, and can be bullied by everyone). The emperor is extremely disappointed with him.
Core conflict: the collision of modern skills and ancient rules; how to survive and rise to power in complex palace struggles; how to reverse the inherent negative impression of the emperor and everyone on the "deposed prince".
Part One: Hiding in the cold palace, showing off his talents for the first time
Part Two: Accumulating Strength, Undercurrents Surge
Part 3: Returning to the field of vision and making waves again
Part 4: Clear the clouds and see the sun, return to the East Palace
