In the second coming of the Heaven and Earth Tribulation City, understanding cannot be improved. The setting of Knowing Blow is somewhat similar to Critical Hit, but it is still different. Critical Hit can increase the critical hit probability through critical hit rate, but Knowing Blow is a basic attribute and cannot be improved.
In The Return of the City of Heaven and Earth, the Wuyun Crystal is a new hidden prop recently launched in the game. Its role is still very important. The character can use this prop to synthesize the Huangyun Crystal Soul. This prop can only be obtained in Chapter 11. The specific way to obtain it is to fight the Phantom Sword. As a hidden prop, the previous original work showed it as the final weapon that can be used to obtain ice glass, but this plot is not shown in Chapter 11. This prop must be synthesized with the Yougen of Luohu City. Just fine. The Wuyun Crystal is actually an item left over from the previous sealing of the Phantom Sword. The character can obtain the Huangyun Crystal Soul after refining the above two props in the King Cauldron.
