As soon as Shen Qingyan took over the "Hundred Theaters" left behind by his father, the property was confiscated by the Marquis of Jing'an on the grounds that "the government was disturbing the people." He was also forced to sign a "labor service to pay off debts" contract, and became the lowest-ranking third-class clerk in the Marquis's mansion. He wanted to keep a low profile and save money to redeem his life, but he accidentally discovered the theft of treasures from the Hou Mansion. The "luminous gear" left at the scene was exactly the same as the machine diagram before his father disappeared.
Major General Xiao Che was ordered to investigate the case, and he labeled her a "suspect" when he first met her: "Don't play tricks in front of me. I have seen more tricks than you." Shen Qingyan rolled his eyes and said, "You will be blamed if you can't find out the truth? I will give you zero points for this operation." From being a scapegoat to a counterattack in the workplace, from decrypting secrets to secretly developing feelings, the two of them were in the "workplace Shura field" of the Hou Mansion. The story escalates all the way, but I don't know that all the clues point to the shocking secret twenty years ago.
