"How could the bronze ball rush down?"

Both of them felt incredible when they saw the bronze ball rushing down.

"We just met this big ball. It was those two people next to me, but it was so hard that it was impossible to get in."

"We can't break the big ball and go in, how could the two of them do it?"

Zhu couldn't believe it when eating meat.

"Yes, I don't think it's possible, it's absolutely impossible, but other people can't get the bronze ball down by such a coincidence."

Both of them were constantly speculating.

"Forget it, stop guessing. We have kept up with this bronze ball and we have saved a lot of effort with it in front of us."

Zhu Yujiu quickly transferred the drilling dragon to the place where the bronze ball had just passed. A passage happened to appear in this place, and the two of them rushed down the passage very easily.

The bronze ball was extremely fast and rushed to a very deep position on the ground. Zhou Xing and the others were in it, feeling the terrible speed and constantly going deep into the ground.

"This should be a guide to go deep into the underground, and it is a special passage for us to enter the underground."

"After all, you are the only one who can open this bronze ball."

The person in the painting said.

"Maybe that's the case. There is no other explanation except this."

Zhou Xing nodded slightly, as if he could not find any other explanation.

At this time, they had already crossed five hundred miles. The rocks in this place were very hard, all of which were very terrible iron ore, and ordinary high-quality swords were difficult to break ore.

If it is the diamond character of the person in the painting, it will definitely not be able to break it and reach this position.

Zhou Xing's treasures are not very good at drilling into the ground, and it is almost impossible to get to this position. Because this place not only has such ores, but also has huge pressure and the power of geothermal heat. Together, Zhou Xing consumes a huge amount of energy every step he takes in such a place.

"It's so fast. We're under 500 miles. Look at the surrounding iron ore. These ores are excellent materials for refining weapons. Taking them back to refine the top-grade emperors and even the peak imperial spirit weapons are excellent."

Seeing the ore around, Zhu Yujiu quickly said.

Only when you reach this position can you get such ore. Many sects use a lot of manpower and treasures to open a mine on the ground, and spend decades or hundreds of years opening up the passage from the ground to this place to take out these ores bit by bit.

However, Bixian Island is an island guarded by Bixian. People here cannot be allowed to mine here, and other strong people will never be allowed to be exclusive to Bixian's treasures here.

So no one will learn from those who start mines here and build mine caves here.

"However, I have been down to five hundred miles, but I still haven't seen the treasure here. The bronze ball is still falling, and I don't know where it is."

Zhu Yujiu said with a frown.

The two continued to follow and rushed toward the ground. With the big copper ball in front of them, they did not waste any effort. As for the heat underground, although the pressure and heat were also very high, their realm was still completely able to withstand it.

With their strength, even thousands of miles underground, they can be fully able to withstand it, but the ground here is too hard, and the power consumed to decline is extremely huge and very difficult, so it is extremely rare to reach below 500 miles.

At this time, they had already followed the big bronze ball and reached a position below 600 miles.

“It’s still falling.”

“How deep should it be?”

The two of them widened their eyes and looked at the bronze ball that continued to descend, feeling very surprised.

But, he continued to follow down.

"Where have we been?"

Zhou Xing and the people in the painting both felt that the speed of the decline was so fast that it was almost a thousand miles away, but it still did not stop.

"boom!"

A strong shaking seemed to be broken, and a layer of red magma appeared underground, which was the geothermal layer that had reached the Xuanming World. Generally speaking, a planet has earth and rock layers, rock layers, and there will be many types and levels of rock layers. Under the rock layer, there will be a geothermal layer, that is, a magma layer.

Below the magma layer, there will be a rock layer. Then, such a rock layer, the repeated magma layer will look like five layers, and each layer will not be lower than a distance of 300 to 500 miles, and there will be a distance of about 3,000 miles in total.

Finally, descending to an unknown level is a super rock layer.

The soil and rock layers on the surface are 300 to 500 miles, and each rock layer is 300 to 500 miles. If you reach the super rock layer, it will be at least 3,000 miles away.

The size of Xuanming’s world and how thick the strata are, is it a secret, a secret that no one can know.

In this way, after entering the first geothermal layer, they passed through hundreds of miles of geothermal layer, leaving a large hole in the geothermal layer, and then entered a rock layer.

Then, it entered the magma layer and the rock layer.

After repeating this five times, the location they were down was already underground four thousand miles away. This location was a place that no one had ever been to.

Even when Zhou Xing and the others were outside the bronze ball, they felt the strong pressure outside and the terrifying geothermal heat.

"We... can't keep up."

Two thousand miles away, Zhu Yujiu and Zhu Yujiu were both helpless. After tracking for so long, he could not keep up with this position.

Both of them looked at each other and felt very helpless.

The deeper level, the powerful magma layer, is difficult for them to withstand. If the rock magma layer above is restored again, it will be almost impossible for them to leave here.

After discussing, the two decided unanimously to leave here.

"Let's go, it seems that we are not suitable to continue pursuing here. It's better to do this. We are waiting outside, maybe we have the opportunity to take action to grab it."

Zhu Chenzi said that.

"Okay, let's wait outside."

Zhu Yujiu nodded and said.

At this time, Zhou Xing and the people in the painting felt that the big copper ball had entered a brand new world, and the pressure around them was still very high, but the copper ball they were in slowly opened, revealing a crack.
