He ostensibly stood by the Idle King and Li Weixian, but he also sent a secret letter pledging allegiance.
He's just a Vice Minister of Punishment, yet he's in favor with all parties, even managing to get along well with the Idle King, that explosive-tempered fat pig, showing himself to be a wily old man.
The letter stated that he was willing to cooperate fully with Qin Zhen in the investigation of the Official Silver incident, to make amends for his actions in hopes that Qin Zhen would speak a few kind words on his behalf to the Emperor, sparing his life.
After reading it, Yan Li'an sneered, "This Mr. Peng is quite the strategist. Right now, it's you against the Idle King, and he's sending a secret pledge of loyalty while also standing with the Idle King. Regardless of which side has the last laugh, he will be safe and sound."
"What a pity," Qin Zhen pinched the secret letter and burned it cleanly in the candle flame, "His efforts are destined to be in vain."
