This Eunuch Is so Upright

Dressed as a eunuch to deliver an edict, as soon as he arrived at Yanmen Pass, King Yan pointed his nose at him and ordered him to kill himself? Zheng Yu'an is numb - in the original book, he is the first cannon fodder to sacrifice the flag. King Yan will either commit suicide because of his love, or he will be the book-traveling boss who sweeps the world. Either way, he will die! What's even more deceptive is the bound-to-death system: if you don't pass the order, you'll be wiped out; if you pass the order, you'll escape death!
