An unexpected operation

The bodyguards skillfully and orderly stuck a bomb on the edge of the alloy door from a short distance away. Very quickly, the entire alloy door and the wall had been installed with explosive bombs. Duke Redington squinted his deep blue eyes as he examined it. After making sure that there was no problem, he nodded slightly. He retreated to the back of the car, and the other bodyguards surrounded him. One of them pressed a button. bang, bang, bang, bang, bang! a series of explosions were heard, followed by sparks on the alloy door. After more than ten seconds, when the last bomb's shock calmed down, the alloy door, which couldn't be moved even if more than a dozen strong men hit it together, suddenly made a dull squeak. Then, the entire frame of the heavy and steady alloy door broke away from the wall and collapsed under everyone's gaze. BOOM! it crashed heavily into the ground. Li yaoyang said,"you actually blew the door open." Li yaoyang still hadn't recovered from the shock.
