Yu Ming's secret weapon was very effective. When Wu Jingguo opened the door to enter the black building, several soldiers standing guard inside the building immediately caught his movements, and because those people did not recognize him as their ally, they immediately charged toward him.
Wu Jingguo held his scimitar at his waist, but he didn't need to use the weapon because he had Yu Ming's secret weapon in his hand. Just like the one tied to Xiao Hei's leg, the black pouch in his hand was also tied with a rope, and after untying it, Wu Jingguo flicked the pouch towards the soldiers, and the poisonous dust immediately came to attack them.
