In the end, Yang Yu still let Gray go.
To smoothly complete the voyage, Gray's steering was essential.
Due to the special nature of Gray's profession, Yang Yu couldn't trouble him until the journey was over.
After Gray left, Yang Yu once again approached the Guard Captain for a brief conversation, hinting that the poison they were infected with might be very similar to the toxin that the King of Wansheng Country once suffered from. If the ordinary antidote couldn't neutralize the toxin, it might be wise to gather good intel and seek a solution to the toxin in the Kafezaro Desert.
Yang Yu also taught the Guard Captain a series of ways to uphold rights when the company didn't want to take responsibility.
The Guard Captain was very grateful to Yang Yu for stepping up, and some of them pooled some money as a thank-you gift for Yang Yu.
