"In Search of Qin", a classic cross-over TV series, I think everyone must be impressed. Xiang Shaolong traveled to the first year before Qin Shi Huang ascended the throne, and mistakenly sent his apprentice Zhao Pan back to qin as a yingzheng, and supported Zhao Pan all the way to the throne of the King of Qin. And Zhao Pan also changed from a idle teenager to a heroic King of Qin, and in the future unified the Six Kingdoms.

"In Search of Qin" is starred by Gu Tianle, Lin Feng, Xuan Xuan and others, Gu Tianle plays the modern xiang Shaolong who crosses, while Lin Feng plays Zhao Pan of the Zhao Kingdom, and The Ying Zheng of the Qin State, who is Xiang Shaolong's apprentice and xiang Shaolong's life. The original Zhao Pan was just a rogue teenager of the Zhao Kingdom, some of them were idle, relying on their mother Lady Ya to barely survive in high society, and after Xiang Shaolong's tutelage, they began to know honor and disgrace, and knew right and wrong.
Although Zhao Pan had some defects in his personality in the early stage, he was still a simple and kind teenager, until he came to the Qin Kingdom, all the way from prince to prince, and then to become a king. Zhao Pan originally relied on Xiang Shaolong for everything, and with the mastery of power and after suffering some hardships, Zhao Pan's mentality was no longer that of a simple teenager, in the words of Xiang Shaolong, "The former Zhao Pan is dead, and now in front of me is the Qin King Yingzheng."
In the "Search for Qin", when he first ascended the throne, Zhao Pan had not changed, and when he sneaked out of the palace because he refused the marriage arranged by Lü Buwei, he was arranged to work as a coolie, Zhao Pan tasted the pain of being enslaved, and also knew the benefits of power, his mentality changed, and he wanted to sit firmly in the position of the King of Qin and control everything.
When Zhao Pan had the ambition and desire to compete for power, he was getting farther and farther away from the teenager who only wanted to avenge his mother. In order to control the Qin state, Yan Yi secretly found a person who was exactly like Zhao Pan and took the opportunity to force Zhao Pan and Zhao Gao to jump off the cliff. In order to dispel Chang Yi's suspicions, Zhao Pan killed two people he met on the road, thus impersonating himself and Zhao Gao's identities and reducing Yan Yi's vigilance.
After Xiang Shaolong returned, Zhao Pan joined hands with Xiang Shaolong to set up a situation and defeat Lü Buwei and Concubine Yi. When Yan Yi had to throw herself into the net for the sake of Zhu Ji and Bao'er, Zhao Pan's face was full of crazy pride, and he fell to death in front of everyone, so that Yan Yi was stabbed to death by everyone. Looking at such a fierce Zhao Pan, Xiang Shaolong realized that the weak teenager Zhao Pan of the past had now completely become a win-win government.
When Xiang Shaolong realized this, he took the initiative to leave with Yingzheng, but he did not expect that Yingzheng wanted to compete with Xiang Shaolong in martial arts, which was originally a very warm sword, but Xiang Shaolong suddenly saw the hostility in Yingzheng's eyes, and his heart was seriously frustrated, so he deliberately let Zhao pretend that he was not strong enough, show weakness to Yingzheng, pretend that he was old and had been surpassed by Yingzheng.
From the change in Yingzheng's eyes, Xiang Shaolong knew that Zhao Pan had completely become Yingzheng, and everything was too late, because in Yingzheng's heart, he was no longer the weight of the past, and there was no warmth. If he continues to stay by Yingzheng's side, sooner or later he will end up with a miserable end because of the four words "Meritorious And High Lord", and both Lü Buwei and Yan Yi may be his lessons ahead.
