The one who placed the cold blade against Yize's neck was Xiao Yu of the Marine Corps. The dagger he had casually picked up from beside Yize was a more reliable weapon for threatening, as cold steel is sometimes more secure. If Xiao Yu had held a high-frequency blade or another type of edged weapon, Yize might have accidentally cut his own throat with a single careless move.
Although Bai Zhongqi did not think highly of Xiao Yu's character, this descendant of the Knights of Destiny possessed some real skills. He led a dozen or so mechanized infantry of the Marine Corps, stealthily infiltrated the camp after activating their optical invisibility mode, and subdued all the guards inside.
This was an attack method far beyond what Yize and the others could have imagined.
