The Sword Tomb Guard

In fact, the sword tomb was fraught with jeopardy, but Jian Wushuang had no idea about it. He was immersed in the comprehension of those sword marks which contained a profusion of mysterious sword essences for him to explore.

"This move combined the Sword Essences of Raging Fire and the Waterdrop perfectly. Though water and fire are originally incompatible, why were these two Sword Essences able to be perfectly combined?"

"This move is so fast and sharp. The Sword Essence of Gale..."

"Darkness. Endless darkness. What is the sword essence of this sword mark?"

While probing the sword marks one by one, Jian Wushuang noticed that the sword essences of Earth, Gale, Raging Fire, and Waterdrop were the most common essences for the sword marks. However, there were also sword marks containing essences that were different from those four sword essences.
