The Sub-demon Race man wasn't anyone else; he was the Four-armed Blade Demon Fred, who came for the assassination.
In the instant Fred saw Lin Qi, he used a high-tier Martial Artist level Step Technique, flashing over a hundred meters to appear in front of Lin Qi. With the Bone Saber polished from Lord Monster's teeth in his hand, he swung it directly at Lin Qi, the speed like a bolt of lightning.
This was also Fred's Super-tier Martial Technique, Glimmering Moon, which he secretly learned in Domain City.
The swing contained twenty-four variations; even a high-tier Martial Artist in the Bone Forging Realm couldn't see through the attack trajectory, let alone defend against it.
With this move, Fred had taken down a high-tier expert in the Bone Forging Realm at first confrontation.
But just as the blade was about to land on Lin Qi, a sudden alarm sounded in Fred's mind, and he instinctively drew the saber to defend against a threat from the side.
Bang!
