Moonsong watched everything from the wall, and he stopped breathing for a moment as he witnessed the sky split and the sword descend. He thought for a moment it was God Ranks descended into Earth. He was worried for a moment before he realized it was Tang Shaoyang's technique. The ground split open just like the sky, leaving a cut mark on the ground in a massive size.
That was proof that The Emperor of the Tang Empire did not slack off during the time he was away from the Tang Empire. That was enough to make him trust Tang Shaoyang even more. The idea of fighting the God Rank was without a doubt an insane idea, but he slowly believed in Tang Shaoyang with just the short show. This was the reason why he stayed behind instead of returning to the border. He wanted to see how strong Tang Shaoyang had become.
