Tang Yizhou is not dead.

When the passage collapsed, he protected the key points tightly, so even though it was buried under the rock, the mechanical tower shield still provided him with a little space.

The mechanical tower shield did not have any damage.

Then Tang Yizhou closed the mechanical tower shield and only retained the physical form as support. He drew out the armor-breaking knife and dug down with that little space.

Because he knew very well that even if he was buried underground at this time, it would not be safe.

Once the mechanical black ant ends the battle with the mechanical bees, the Scorpio Legion can send a landing team to kill him at any time, or simply have a few more ground-boring bombs once and for all.

Or the only good news is that Da Zhuang and Xiao Hei didn't have any trouble. They were digging rocks hundreds of meters away and wanted to rescue him.

Looking at the time, it was already six:15, and there were still fifty minutes left to leave, but this was not a good thing, but it was bad, because it would mean that he would appear here again in twelve hours.

So he had to take this opportunity to escape from the area.

But I don’t know if it was too unlucky or the mining passage below collapsed again. After less than a few minutes of digging, the earth shook again, and the collapsed rocks poured downward like a torrent. This time, even Dazhuang and Xiaohei were not spared.

The only thing Tang Yizhou can do is to grab the mechanical tower shield, as pitiful as a small boat in the sea of ​​anger...

In just over a dozen seconds, he felt that he fell down by at least hundreds of meters again.

There is no doubt that there is definitely a huge space below. This may have been dug out by mechanical black ant mining. After being bombed by more than a dozen ground-boring bombs, it collapsed.

Fortunately, he was wearing mechanical exoskeleton armor and protected by mechanical tower shield, but he was still not injured. Even the two unlucky guys, Dazhuang and Xiao Hei, were not injured. After all, their defense was thicker, but they were now buried by rocks. How long did it take to break free?

"It seems that running upwards is meaningless."

Tang Yizhou smiled bitterly. He was originally five hundred meters away from the ground. When the first explosion collapsed, he fell about 800 meters deep, but now he fell at least nearly one thousand meters deep.

He could only use the mechanical tower shield and then continue to dig with an armor-breaking knife. This time, he was lucky that there were three rocks as big as a house stuck in this area, which was very stable. He could easily dig out a space and cushioned the excavated gravel under these three huge rocks to make them more stable.

Then Tang Yizhou identified the direction and continued to dig forward. He didn't have time to rescue Da Zhuang and Xiao Hei, so he had to find a way to escape further.

While digging and carrying stones to form support on both sides, he quickly cleared out a passage, which was very fast because the rocks were all in blocks. He only needed to cushion small pieces of rock under the large pieces of rock, and when he encountered large pieces of rock, he would take a detour, so it was very smooth.

Of course, the giant-jawed black ants that were hit in this process were also packed together. He even dug up a team of golden armored giant-jawed black ants, a total of twelve, which were obviously newly evolved black ants soldiers. Unfortunately, they died before they could succeed. Oh, and one of them was one that was not hit to death, but was pressed by a huge rock. Now all of them are cheaper in Tang Yizhou.

This golden-armored giant-jawed black ant is about three times that of an ordinary giant-jawed black ant. It weighs about 600 kilograms and has an average metal value of 85 points. It is fierce and comparable to a wild dog tyrant. I guess even if it is not a legendary combat power, it must be a quasi-legend.

However, time was tight at this time, so Tang Yizhou put them in a mechanical backpack and found a way out.

At 6:45, he cleared a passage more than 200 meters long, and then he touched the rock layer, the complete rock layer, which was not affected by the explosion, but traces of mechanical black ants could be seen on it.

"So this should be the edge of collapse, it's great."

Tang Yizhou was overjoyed and quickly continued to clean up the rock layer downwards, because the cleaning speed was faster than simple excavation. With the addition of mechanical exoskeleton armor, it was not too easy to lift a large stone. After a few minutes, he encountered a huge stone in the gap in the rock layer.

It is precisely because this stone is stuck here that a dark gap is left next to it. Tang Yizhou shines it with a flashlight, but it is bottomless.

So he shot out a mechanical spider silk and went down easily.

Surprisingly, the gap is very deep, and I don’t know how crazy it was to mine here by the mechanical black ants. This is the rhythm of the entire planet being mined.

The mechanical spider silk became longer and longer, and Tang Yizhou was not worried. He had stored it for a thousand meters before.

As a result, a few minutes later, his face changed.

Because the one thousand meters of mechanical spider silk is about to disappear, but the gap is still bottomless. What's the matter? He didn't find such a deep mine when he was exploring it before?

There was no choice but to use the armor-breaking knife to insert it on the rock wall and walk down alternately.

He walked down for about ten minutes and was still not at the bottom, but Tang Yizhou felt very strange in his heart, because it was already sunset and dusk, so why hadn't he left yet?

So he climbed down carefully again. Ten minutes passed, but there was still no movement, but the sunset should have passed long ago.

This is strange. Could it be that the condition that triggers reincarnation must be on the surface of the earth?

Tang Yizhou was thinking this way and accelerated his way down. He was becoming more and more curious now. What exactly is there?

About fifteen minutes later, the crack finally bottomed out. At this point, he estimated that the place was at least 3,000 meters away from the surface. He checked around with a flashlight and Tang Yizhou once again confirmed something that this crack was not caused by mechanical black ant mining, but was cracked due to the bombardment of ground-based bombs and the collapse of the passageway.

Only one person could stand at the bottom of the crack, so he immediately used an armor-breaking knife to dig it out. The rock on the left was easily chiseled open, and the rock on the right was the same. Only the rock under his feet, he chiseled it casually, and it was actually bounced back by a force, and the armor-breaking knife almost got out of hand.

Tang Yizhou was surprised because, logically speaking, there was no such hard natural rock on this planet, because even diamonds had a metal value of only 20 points.

The metal value of his armor-breaking knife is as high as 65 points.

"There is something wrong with this stone."

Tang Yizhou shone with a flashlight and found that the rocks under his feet were completely different from the surrounding rocks, which was simply the difference between heaven and earth.

He dug out all the rocks above and cleaned up a large space. When he looked at them again, he was even more shocked. The surface of the rocks below was as smooth as marble, and even as transparent as jade. The patterns inside were complex and full of beauty, which almost made people think that there was an immortal palace below.

When Tang Yizhou activated the metal detection skill, he was even more stunned because with his level 35 metal detection, the information he obtained was actually zero.

It's completely unsightly to see through.

"It's not the edge of the dungeon, the legendary cornerstone layer?"

"But it shouldn't be. According to my understanding, this second layer of copy should contain a very large starry sky, and even the Milky Way must be included."

Tang Yizhou thought of the space base he left through the mechanical matrix for the first time. He did arrive outside the atmosphere of Blue Star No. 13 with others on a transport spacecraft, and then took a landing chariot to enter the surface. The whole process was normal.

Even if it is not good, the second layer of dungeon should have covered Blue Star No. 13. How could the edge of the dungeon appear three thousand meters underground?

I can't figure it out, I can't think about it, and I can't even put this kind of thing into the level five calculation skills.

However, he should have returned to the first copy at sunset today, but he did not leave, which might be related to this strange underground cornerstone.

Tang Yizhou studied it carefully and looked at the speed of his conversion power at this moment. It was still 1,800 grids per hour. This radiation energy was bursting, so although the power consumption was very large this day, he was not short of power now.

He wants to try it to see if he can break through this cornerstone layer?

However, his existing weapons and industrial materials are not enough.

When he was digging the rocks before, he just picked up eleven golden armored giant-jawed black ants and killed one, which led to the hunting memory of golden armored giant-jawed black ants.

This hunting memory is very awesome, called reflex attack, which means that the golden armored giant jawed black ant in the middle not only has a very high defense, but also can eject most of the attacks. It is simply the nemesis of a ranged unit. With an average metal value of 85 points, even if you send a crow tyrant, you can't kill one.

That is, the mountain collapsed and hundreds of thousands of tons of rocks fell down, which killed them alive.

You can imagine how awesome this would be if you arrived on the battlefield.

At this time, Tang Yizhou took out the corpse of a giant-jawed black ant with golden armor and then activated the decomposition and refining skills. Because there is a hunting memory, it can be successfully refined 100%.

A few minutes later, after consuming a full 5,000 grids of electricity, Tang Yizhou successfully decomposed and refined it successfully.

A weight of 600 kilograms was obtained after the refining was successful, and only six kilograms of metal powder was obtained, but when scanning with metal detection, the metal value was as high as 125 points.

Become rich.

Compressing the surprise in his heart, Tang Yizhou took out the corpse of a giant-jawed black ant without saying a word, and directly used special smelting to force it into a cylindrical steel ingot. Then he used heat treatment skills to add the metal powder he just obtained, then strengthened it with a blue industrial ball instead of forging, and finally used special cutting skills to cut it into a sharp drill bit.

After it cools down, it will be heat treated again and strengthened again. Finally, he removed the spider engine and installed it on the drill bit.

This process is not very complicated. It is mainly because the spider engine operates simply. As long as the electromagnetic force field is formed and its parameters are adjusted, it can rotate at high speed with the drill bit.

At this time, the metal value of this drill bit had reached 115 points, which was a magic weapon created by Tang Yizhou.

He threw ten golden energy balls into the spider engine, and he aimed at the rock that was so beautiful on the ground, and made a slam.

The strange rock layer naturally produced a huge force, almost bounced the drill bit away, but Tang Yizhou was ready and pressed with all his strength. He heard a harsh scream. The almost impossible rock layer was drilled out of a hole as big as a fingertip, and a kind of colorful debris flew.
