Return of Proton: Blood Blade Tianlan City

Eight years ago, the Zhenguo General's Mansion was falsely accused of collaborating with the enemy and everyone was executed. Chu Jin, the only surviving young son, was sent to the enemy country as a hostage and endured the humiliation. Now that he has returned, he appears to be a hostage in the peace talks between the two countries, but in fact he is a vengeful ghost. In the court, he is the gentle and jade-like hostage; in the dark night, he is the Shura who harvests the lives of his enemies. As the truth gradually unfolded, he discovered that there was a bigger conspiracy behind the family murder case - a secret that could subvert the world. The blood debt must be paid with blood, but when he faces the daughter of his childhood sweetheart and his current enemy, can he still cut down the sword of revenge without hesitation?
