Liu Dong Ming and his companion were killed in just a blink of an eye.
Liu Dong Ming had no intention to fight Du Qian Jun as soon as Du Qian Jun and his companion brought out mediocre divine artifacts. Initially, he thought the person he knew as Du Yan who had a similar cultivation base with him would also have a primitive divine artifact. However, not only did his opponent has a mediocre divine artifact, but his opponent's companion also had a mediocre divine artifact. Moreover, Du Qian Jun's companion was not any weaker than Du Qian Jun. With this, the difference between their strength was too wide.
Nonetheless, at that time, Liu Dong Ming did not panic. After all, he thought he still had Sima Han and his companion supporting him. He thought with Sima Han and his companion's help, the four of them would be able to safely escape into the Divine Sanctuary. Who knew that when he turned around to ask for help, Sima Han and his companion had already lifted their swords.
