It is the proud work of the master swordsmith Ou Yezi. He once killed the king Tiao with his sword energy, but eventually died together with Jing Ke in the palace of the King of Qin.
Ying Zheng combined the two swords into one, still named him Lu Lu, and became the King of Swords. It is also called the Imperial Sword, but it is also a cursed sword. The most beautiful woman in the Three Kingdoms killed herself with this sword, and the eighth son of Emperor Kangxi of the Qing Dynasty died due to this sword...
Three young men with their own secrets were involved in the torrent of history because of this imperial sword. They watched Jing Ke assassinate Qin, but failed at the last moment. They watched Diao Chan give the sword to the person she loved most, but she was killed by the sword. They watched the eighth prince Yinhu desperately wanted to kill the person holding the sword, just because of a groundless rumor...
Even though he was unwilling to do so, the legendary life of the Emperor Sword made Prince Ming, the second prince of Wuyou World, have to admit that he was trapped in an endless conspiracy and could not escape. The truth was so cruel that it was enough to make his world collapse.
