Meng Yi served in Qin Shi Huang's court as a minister and was one of the emperor's close aides and advisors.
Meng Yi went by the book and noted that Zhao Gao was to receive the death penalty and be stripped of his official titles.
[4] In the winter of 210 BC, Qin Shi Huang became seriously ill while he was on an inspection tour in eastern China so he sent Meng Yi to help him pray to the gods on his behalf.
Before Meng Yi returned, the emperor died at Shaqiu (沙丘; south of present-day Dapingtai Village, Guangzong County, Henan), with only Zhao Gao, Huhai, and Li Si by his deathbed.
Fusu faithfully followed the order but Meng Tian felt suspicious and repeatedly requested for confirmation, but was placed under arrest.
Meng Tian, who had already been arrested earlier for defying the edict, was imprisoned in Yangzhou (陽周; around present-day Yulin, Shaanxi).
In the film, Meng Yi is reincarnated as a present-day archaeologist who embarks on a quest to find a mysterious element that can make objects hover in air.
Like his older brother Meng Tian, he studied under Lord Changping, and learned tactics and strategy alongside He Liao Diao (Ka Ryo Ten in the series).
