Bind Game Players, I Rely on Commission to Upgrade

Lin Chuan travels through "The World of Sacred Heritage" and encounters a "terrible binding system" - he has zero experience in killing monsters, and his upgrades are all based on commissions from tasks given to bound players. The key is that the successful extraction function is not visible. If a player discovers it, he will die on the spot! I wanted to secretly act as a hands-off shopkeeper, but in the end, all the bindings were "ancestral-level living treasures": the warriors were brave and foolhardy, and rushed regardless of their health bar when they got angry, and they couldn't stop them; The mage is good at calculations. When it comes to tasks, he will first calculate the profit and loss. The mechanic has a high IQ but poor understanding. When he is asked to go shopping in the East Market, he first tilts his head and asks, "Which way is east?" In order to upgrade and save his life, Lin Chuan could only secretly act as a "nanny behind the scenes": while preventing the soldiers from dying, he was trying to figure things out with the mage, and he had to draw a map for the mechanics, all for fear of exposing the secret of the commission. How did the promised time-travel counterattack turn into a high-risk worker?
