He first had the others step back. After taking a deep breath, he dropped into a horse stance and planted his feet firmly. Power surged from the soles of his feet into his upper body, and finally, aided by his back and arm muscles, he unleashed a charged punch as fast as sound.
The straight punch broke the sound barrier, sending a sonic boom's shockwave rippling through the air.
As his fist connected with the lock core of the steel gate, a terrifying force approaching one hundred tons, amplified by its sonic velocity, was transferred into the gate.
The next moment, the coat of anti-rust paint on the supposedly Indestructible alloy door shattered. Then, the extremely hard alloy began to twist and deform, absorbing the force from the punch and letting out a deafening crash.
Fortunately, the mountain rock above absorbed the energy of the sound waves, preventing the noise from traveling for kilometers.
