Being unable to enter the building didn't mean he was out of options.
Li Ang gripped the seams between the wall bricks with one hand while quickly pulling out a [Ruitu Military knife 300] from his backpack with the other. He pinched the middle of the military knife and, with a gentle rub of his thumb, slid out the small shovel attachment. He then released Ripple Energy, infusing the tip of the shovel with it.
With a crisp CLANG, Li Ang, holding the knife handle, inserted the shovel horizontally into the seam between two bricks directly below him. Then, bending his body with one leg forward and the other back, he crouched nimbly and steadily on the knife handle, like a gargoyle statue.
All of this happened in a flash of flint and stone, before the Black Trojan could even react.
Li Ang had already taken a steel rod as thick as a bowl's mouth from his backpack, gripped it with both hands, and swept it toward the disguised man.
