Originally, Zhao Hai's guns and cannons were not that powerful. But now, Zhao Hai added the yin-yang Thunder pond into the bullets. However, because the bullets were small, the yin-yang Thunder pond should not be so powerful. However, Zhao Hai and the others were in the cloud Sea realm, and in the White cloud continent. Zhao Hai found that his yin-yang Thunder pond could exert more power here, which was why the bullets and cannonballs were more powerful.
It was precisely because his bullets and shells were so powerful that the immortal stage powerhouses stopped. It should be known that Zhao Hai had used 2000 cannons and nearly 100000 guns for this attack.
