Handing: My Mastermind Is Guo Jia

He traveled through time. There is no system, no golden finger, just a strange body and the corpse of a Manchu.
The day Liu Yan woke up, pressing on his chest was the cold body of young Liu Yan. He used his nails to dig through the frozen soil, burying the body's past, and then took out the only thing that belonged to him from his arms - a 21st century windproof lighter.
He used this "auspicious sign" to knock on the eunuch Zhang Rang's door and exchanged it for the seal and ribbon of the Hanzhong prefect. But he didn't know that this deal would make him reviled by scholars all over the world as "the eunuch who was destined to be the eunuch" many years later.
When he met Guo Jia, that man was drinking in Fenghua Building. Guo Jia asked him: "Brother, did you have any plans to pay for Jia's drinks?" He said, "Yes. I want to establish myself in Luoyang, and I need to know people."
Guo Jia smiled: "Brother, you are sincere."
Later Guo Jia stayed in Wuguan He waited for him under a dead tree for three days and said: "Jia has arrived."
What happened next will not be written in History books -
When the young man named Wang Gouer died in front of him, he knelt down and burned a stick of incense, then stood up and issued an order for him to be compensated.
When the aide named Du Xi was assassinated, he had an unfinished volume of "Six Matters for the Peace of the People" under his body. He sat in Du Xi's old residence all night, and then wrote to add the seventh article.
The team leader named Li Shuang committed a capital crime. He cooked the decapitation meal with his own hands and said, "I can't keep your life, but I will support your mother."
The woman named Liu Sanniang was blocking the street with a curled kitchen knife in her hand. Her son later held the knife, walked up to him and said, "My mother said that Liu Shijun kept his word."
