Zhang Ruochen had frightened Xue Tu badly. He was uneasy and full of fear for this trip to the Forest of No Return.
It was difficult for even a god to frighten a Supreme Saint to such an extent.
Zhang Ruochen only had hatred for Xue Tu. He had no good impression of him.
In the Sword Vault Palace battle, his senior brother Bao Lie had almost died at his hands. Even Zhang Ruochen himself had almost lost his life. It could be said that there was a great hatred. If Blood Empress had not taken Xue Tu as her disciple, Zhang Ruochen would not have let him off so easily.
However, Zhang Ruochen had just said those words to scare him.
A Supreme Saint could be killed, but not humiliated.
If Zhang Ruochen forced Xue Tu to such an extent, even if he had to die, he would never submit.
