Zhong Yue heaved a breath of relief when the three left. Then, he looked up to the sky with a stern face.
It wasn't him who killed Shen Xiage nor was it Great Si Ming; it was the Heavenly Dao, Heaven's power.
Back in the Space Bottle, he had Shen Xiage, Feng Yuhuan, and Xie Yang vow to [Tian Yin], the skill of the 14th Drawing of Heavenly Daos. The vow was not made to him, but to the Heavenly Daos.
The vow was not easy to do, it was only possible because Zhong Yue had mastered a Heavenly Dao's skill. In turn, if it were someone who didn't know a Heavenly Dao's skill like him, the vow to the Heavenly Daos wouldn't even work at all.
Fortunately, as he had studied and cultivated a Heavenly Dao's skill, the vows Shen Xiage, Feng Yuhuan, and Xie Yang had made to the Heavenly Daos were considered effective; thus, the happening of the vow abnormalities and brandings.
