Adviser to the Empress and Bailong

Here’s some lore

The advisor is Bailong's last mentor. After the previous mentor left Bailong and the city, the young disciple passed into the hands of an advisor. He begins to brutally train Bailong, literally beating him up, wanting him to become worthy. Meanwhile, he puts pressure on him and manipulates his relationships with his loved ones so that he is afraid of him. The adviser's only goal is to become emperor, which he soon succeeds in doing. The adviser is really afraid that when Bailong grows up, he will easily be able to dethrone him from the throne, and therefore tries his best to instill fear. Also threatening to execute his close friend, the adviser instructs him to kill rivals and relatives of the former empress so that they do not rebel. Bailong's friend will be executed anyway, despite the completed assignment. The young man grows up, escapes from Shenzhen, and meanwhile the adviser is overthrown by the Empress's general.
