Yes, according to Historical Records, Jing Ke was supposed to take him to stab the king of Qin as his assistant, but because he lived in an uncertain place, he could not be found, so Jing Ke could only take Qin Wuyang. But because Qin Wuyang saw that many military men in Qin were guilty and turned pale, Ying Zheng saw the flaw, which led to Qin's failure. Thus, our non-participation indirectly led to the failure of the Qin thorn plan. However, history has passed for two thousand years, and there is no need to pursue local problems. Even if Qin succeeds in stabbing Qin, Qin can still destroy the six countries. Qin's army claimed to be the strongest in the Warring States, and later even the Huns were afraid. Even if Qin Shihuang is assassinated, many famous generals of Qin State are still alive. Of course, they can support another king with their own abilities. It is worth mentioning that Ying Zheng was only about 20 years old at that time, and in popular parlance, he was a brat. He won the world by relying entirely on his elite troops and outstanding generals.
