The moment Xiao Shi broke the seal of the Emperor's Equipment and escaped from the Emperor's Shadow, He had already realized that it was too late for him to stop the Martial Emperor from killing Demigod Xingkui. The only thing he could do was to attack faster than the Martial Emperor and kill Demigod Xingkui first.
In any case, Demigod Xingkui's death was inevitable. Instead of dying at the hands of the Martial Emperor, it was better for him to end him.
Xiao Shi had to take this life!
The current situation was already a little passive for him. Once the situation developed according to the Martial Emperor's plan, nothing would be able to reverse the situation as long as the Martial Emperor obtained Demigod Xingkui's rules.
After all, Xiao Shi believed that he would definitely not be able to defeat the Martial Emperor in the competition for the rules of heaven and earth.
