Remembering the Red Mansion

Programmer Jia Cong died suddenly while working overtime and became the most disliked bastard in Rongguo Mansion. What's worse is that when he passed through, the original owner of this body had just been poisoned to death. Who did it? Why? He opened the bookcase left by the original owner: thousands of taels of banknotes of unknown origin were hidden in the secret compartment; the book pages were filled with strangers' names such as "Tongzhou" and "He Wanchuan" in the annotations; two large cabinets were locked, and it was unknown what was inside. Daiyu burst into tears when she saw him. When Baochai saw him, he stopped talking. When Yongjing King Zhao Heng saw him, he called him "God of Wealth". Everyone is looking for the shadow of another person in him. And that person - is dead. He decided to find out the truth. Using the imperial examination as a ladder and reasoning as a sword, we uncover the four-fold code and five-layer murder puzzle left by the original owner layer by layer. What he didn't know was that the original owner was a time traveler just like him. The original owner didn't know it until his death - the "fortune teller" he helped was an orphan girl disguised as a man. "I'm not him. But what he didn't finish, I finished for him."
