The emperor's master was wronged, and his seven disciples were burdened with blood feud and were poisoned by the strange poison "Seven Years Cicada".
This poison is a sharp sword hanging over their heads - within seven years, every autumnal equinox, one person will be poisoned and die suddenly.
There is no antidote, no rules, who is next depends entirely on God's will.
Desperate? No.
When death becomes the destined end, they choose to become chess players, playing chess with the sky and power! Prime Minister Quan: "How can a mere summer cicada hope to survive the autumnal equinox?"
Every time they take action, it is a thunderous strike that is calculated to the extreme, leaving no way for them to retreat, because they have no way to retreat.
After seven years of cicada chirping, the show begins!
Purpose: To live towards death and to restore the purity of the court
