Su Ziyang looked at the city wall and saw that the durability would be restored to some durability every once in a while, and it would increase faster than it would fall.

Seeing this scene, Su Ziyang frowned.

This is a problem, and you must refine more advanced siege tools.

"Master!"

At this moment, Feng Yunhe ran forward.

"What?" Su Ziyang asked.

"Lord, this city wall was refined by a powerful man of honor. It has special restrictions in it and the energy source is constantly repaired. Not to mention your third-grade siege weapon, even the sixth-grade siege weapon will not be able to break it!" Feng Yunhe said.

"Then what good will you do?" Su Ziyang asked.

"Lord, only by using seventh-grade siege weapons can you break through!" Feng Yunhe said.

"Seventh grade?"

Su Ziyang frowned, opened the refining panel, and began to check out siege tools.

The seventh grade, the sky-shaking hammer, the materials required: Diamond crystal, Black Spirit Crystal, and the marrow of Xuanyin.

Seeing these three things, Su Ziyang's eyes flashed.

I already have the marrow of Xuanyin.

The other two things are not available at the moment.

"Black Spirit Crystal, it seems there is one in that place!"

In Su Ziyang's eyes, a brilliance shone.

However, there is also the Diamond Crystal, but I don’t know where to go.

If this is the case, this Poshan Palace will not be able to be broken for the time being.

"Do you know where there is Vajra Crystal?" Su Ziyang asked.

"Lord, I know this. In the Apocalypse Continent, only the Xiluo Empire has Vajra Crystals. They are extremely strict in control. If other forces want to find a piece, it will be difficult to reach the sky!" Feng Yunhe said.

"The Westward Empire?"

Su Ziyang opened the map and found the location of the Xiluo Empire, and his eyebrows were furrowed.

Between the Xiluo Empire and the Valley of the Evil, there are two dangerous places, Ghost Dragon Valley and the Doom Swamp. If you want to go there, you must travel through the two dangerous places. Moreover, the journey is more than 10,000 kilometers, which is extremely far away.

"Forget it, let's talk about the breaking of the Poshan Palace later!"

Su Ziyang murmured to himself and made a decision secretly.

Then, he swept his eyes to everyone and said, "Stop siege!"

"Yes, lord!"

All the siege weapons were retreated back.

"Master!"

At this moment, Zhao Chan led the army and arrived quickly.
