Reverse!
These two words were the quintessence of reversing Yin and Yang, vividly displaying this divine essence type mental cultivation method.
Based on Xu Bai's current knowledge, reversing Yin and Yang should be a mental cultivation method of Taoism.
Using the divine essence as a guide, it affected the aura of the entire body to confuse the enemy.
After fusing with the Four Slaughtering Heart Technique, it became a chaotic mess, and its power was even stronger.
From god essence to true essence, using true essence as a guide, when used, it could be used to confuse the real with the fake.
To put it simply, when Xu Bai slashed with his saber, under the guidance of his True Core Strength, the enemy would feel that it was illusory.
This slash would become both real and fake, making it difficult for people to figure it out. He could even make people think that this slash was fake, but it was actually real.
