It's uncertain if Master Ren Mu and Master Yan Gao have ever engaged in a battle, but their combat capabilities should be quite comparable.
As peak Great Cultivators of superpowers, even if there are some differences in strength, the gap between them wouldn't be significant.
Li Shiming previously thought that after hearing of his victory over Master Ren Mu, Master Yan Gao would not come to Dongqi Continent to trouble him.
Although he had a deep grudge with the White Emperor Sect, if his strength were formidable enough, the White Emperor Sect would tacitly accept the situation.
It's essential to know that the reason Li Shiming killed three Great Cultivators of the White Emperor Sect was because the sect initiated an attack against the Ten Thousand Beast Sect. Li Shiming's actions were justified, aligning with the rules of the Cultivation World.
