For cultivators, even if one was stronger but the other took out low grade immortal artifact, he might even leave immediately.
But Ye Mo wasn't afraid at all, even though he didn't have a low grade immortal artifact, he didn't believe Zi Xu was weaker than any low grade immortal artifact. Plus he had a low grade immortal artifact but he just hadn't spirit controlled it. Wang Xie gave him a thin blade at West Extreme State that was a low grade immortal artifact, but he didn't like it.
However, the powerful killing intent swept out forming spirit chi that swept at Ye Mo. All cultivators nearby quickly retreated.
Being scraped by the sword ray and killing intent of the immortal artifact meant death.
Ye Mo found that Shui Ye couldn't control the actions of the sword either. The sword howled as though wanting to devour people. Ye Mo released Zi Xu and hacked out with Illusion Cloud Hua Mountain Strike.
