"So, you used a sword formation that you don't even know how to use to make me happy?"
"Uh ... It's mainly because since the Twilight of the Gods, the yin and yang dust formation is usually formed by dozens or hundreds of sword Immortals. I didn't expect your talent in swordsmanship to be so great that you could activate it alone, so I bragged on a whim ..."
“....”
His devilishly handsome eyes stared at the old man helplessly, and he finally let out a long sigh.
"The most important thing is that the celestial slaying sword formation is one of the most powerful world-destroying formations, and it has been under the direct command of China since the ancient times. It doesn't have a physical body usually, and it will only be controlled by the four Dragons of the country when China is in a war. It's completely different from the yin and yang dust formation that was passed down by our Mount Shu sword sect."
