As for the Tai'e Sword, its background is even more significant.
The Yuejue Book clearly states that this sword was forged by Ou Yezi and Gan Jiang for the King of Chu.
During the forging process, the sword was quenched with water from the Chi Spring, using the essence of five metals as material. On the day the sword was completed, it caused the winds and clouds to change colors, and its aura shot straight towards the celestial axis.
Back then, the State of Jin coveted this sword, besieging Chu for three years. The King of Chu preferred death over surrender, standing on the city wall with the sword, which somehow emitted the intimidating aura of the sword, thus deterring the Jin army into retreating without battle.
Thus, the Tai'e Sword earned the title "Sword of Majesty."
Some described its sharpness with the phrase "Chopping cows and horses on land, striking swans and geese on water."
