Background: The seven-star needles in the old man's spine were more powerful than he expected. Although he tried his best to force out the poison, Sun Yubo finally had to admit: the seven-star needles in his spine could not be forced out in a short time. What was worse was that the seven-star needles in his spine could not be forced out at the same time. They had to be forced out seven times, one at a time, otherwise the poison would backfire and his life would be at risk. It finally took him seven years to force out all the seven-star needles and needle poisons from his body. This is a story for another day. There was actually another exit in the well. Therefore, after Sun Yubo confirmed that the Seven-Star Needle could not be forced out in time and assessed the current situation, he decisively left the well and met with the Tiger Group led by Yi Qianlong. He canceled the original plan and evacuated outside the pass, conserving his strength in order to climb again in the future. Meng Xinghun, who then went down to the well, also escaped from another exit based on the hints left by Sun! Later, he used his tracking skills to catch up with Sun and reunite with him, and was persuaded by Sun to "lurk" and heal his wounds outside the customs. Seven years later, when they entered the customs again, they caused another bloody storm in the world. . .
