The reason why the clothes on the white-robed men could expand quickly was because when they pressed the button, a specially compressed high-pressure gas was released and filled the surface and inner layer of the clothes.
There was a special sealed cortex there. The gas that was sealed was filled in it and would not leak out at all. As for the high-pressure gas, the resistance and tension brought about by it was not inferior to the bulletproof vest at all. It could withstand a very strong impact.
With such a powerful resistance, his defense was maxed out. Even if he used a pistol to shoot at the clothes on the white-robed man, he would have to shoot at the same place more than three times before he could penetrate it.
No matter how powerful Su Yun's silver needles were, they were only in the first realm. They did not reach the penetrative power that a bullet could achieve. This was also the reason why the white-robed man was confident and arrogant.
