Introduction: Qin Xianglin traveled through the Warring States Period and the Qin Kingdom. After half a year of hard work, he finally awakened to the golden finger that could listen to Ying Zheng's heart. By chance, he meets the young King of Qin who leaves the palace incognito and is controlled by Lu Buwei and Lao Ai. He relies on his mind-reading skills to break through Ying Zheng's knot in his mind, and sets the three rules of master and apprentice to accept the future First Emperor. He refused to accept the gold and silver apprenticeship ceremony from all over the hospital, completed the task of being a national master, unlocked the time and space store, and exchanged it for a special secret medicine. Three days later, he accompanied Ying Zheng to the appointment, planning a perfect plan to get rid of Lao Ai, and clear the biggest obstacle to Ying Zheng's pro-government.
