Before he could feel sad, he suddenly traveled to Dashun, an imaginary dynasty, with a flash of darkness in his eyes. What's more terrible is that he also transformed into an ancient profession with a mortality rate of 99.99% - A secret guard. Just be a secret guard, but his cheap employer, the Fifth Prince Chu Jinyou, was suddenly assassinated. Shen Yichu didn't want to receive the lunch box so hastily, but he also didn't want to stand out among the many secret guards, so he had an idea and swooped behind Chu Jinyou to fight for his life. The result is that he himself is intact, while the cheap employer becomes disabled... The guilty Shen Yichu didn't know whether the online medical practical courses he had learned could make up for his cheap employer. But with Chu Jinyou's murderous eyes, he was stunned and said: "There is a folk remedy from my hometown, how about you try it?" For some reason, Chu Jinyou didn't punish him. Instead, he asked him to perform his duties as a secret guard as usual and left the matter undisturbed. It's just that his daily salary has become precarious. Shen Yichu, who almost had to take out a loan to work, couldn't bear it any longer. He angrily came to his employer and poured him a cup of good hot tea under his cold eyes. He stayed with his employer, not only helping him heal his broken leg, but also transformed into a cross-dressing boss to steal information from other rival princes' houses. Other princes: Don't steal, don't steal, the toilet paper in the palace has almost been stolen... Cheap employer Chu Jinyou: If you don't do things well, I will fine you a year's salary. Is there any doubt? Shen Yichu: Don't stop me, I must resign today! I won't do it anymore, I won't do it anymore! Chu Jinyou smiled softly, "It's not up to you." Attack: Let's kill this secret guard who is picking his feet. Shou: Brother, don't do it, I have this, and this... Intention: Let yourself be the light that illuminates others.
