After digging down five or six more boulders, Yu Fei looked at the last usable breaker in his hand and couldn't help gritting his teeth. If he used this thing out again, he would have to rely on his fists to remove the remaining boulders.

It was broken with cold weapons.

Rumble…

The breaker that used gasoline as power started working again, but another embarrassing thing happened. That is, Yu Fei dug too deep. The air here was not circulating, so there was insufficient oxygen, and the breaker was not strong enough. Even

It also shuts off automatically again and again.

Even the exhaust gas produced filled the narrow passage and was a bit choking.

Yu Fei was not without a solution. He took out an oxygen tank from the Dragon Ball space and quickly opened it to the maximum. Suddenly, a chirping sound was heard, which dispersed a lot of the surrounding smoke, making it easier to breathe.

A little smoother.

Then Yu Fei opened the breaker. With sufficient oxygen, the breaker could work again.

After breaking through six boulders in a row again, Yu Fei paused for a moment because he found that the boulder below was different from the others!

The size of the boulder below has increased rapidly, and Yu Fei dare not destroy it at will. Once it is broken, the damage to the overall structure may be catastrophic.

Yu Fei had no choice but to stop and use his spiritual energy to explore again. He had stopped on this rock before.

The size of this boulder exceeded Yu Fei's imagination, because Yu Fei's spiritual energy continued to penetrate deeper and deeper, and finally reached the end after going ten meters. Then Yu Fei discovered that there was actually a space under the boulder!

The bottom of this boulder is empty, which can explain why this boulder is so big, because it is used as a support for the space below.

Then Yu Fei explored it to the left and right, and found that it was bigger, and the boulder extended about fifteen meters to the left and right.

So this means that this boulder is like a cover, and its purpose is to use its huge volume to create a safe environment for the space below and protect the things in the space below.

Yu Fei was glad that he did not recklessly use a breaker to try to break the boulder. Otherwise, once the boulder was destroyed, the result would be unimaginable. The terrifying landslide could instantly crush him into a pulp.

But before Yu Fei's goal was achieved, this huge boulder became a roadblock, and it couldn't be destroyed. How should Yu Fei continue to explore?

Yu Fei was not in the middle of the boulder, so Yu Fei thought for a while and finally decided to try to cross and find the entrance to the space below.

However, the crossing was not done recklessly, but Yu Fei began to use spiritual energy regardless of the cost, first trying to find the entrance to the space below, otherwise it would be really tragic if he chose the wrong direction and ended up going in the opposite direction.

Although the spiritual energy contained in the stone would be very depleted, and it would be very difficult for Yu Fei to control it if the distance was far away. However, in order to save energy and time, Yu Fei could only explore it at any cost.

It took Yu Fei half an hour to figure out the size of the space below, but he couldn't find the entrance. It seemed that there was no entrance or exit, and the place was sealed off during construction, and there was no intention of letting people in.

However, although he did not find an entrance or exit, Yu Fei finally found a way to enter the space below. Although the top of the space below is supported by a huge stone as the top, the side walls are not. They are built with walls.

, a wall built with the same boulders as above.

The stones are also stacked in a staggered manner, so as long as you dig to the side, you can break a stone from the wall and use it as your own entrance and exit.

But if we follow this idea, the length of the detour will be at least thirty meters, which is equivalent to digging down thirty meters. This is definitely a big job for Yu Fei, who has been working without sleep for three days.

quantity.

But now that we are here, of course we can't give up. Yu Fei has to plan the route carefully. Before, he was digging vertically downward, so the possibility of collapse was small. But this time he was digging horizontally, so he had to consider the rocks above.

There is a problem with support, because once you break the stone below, the stone above loses support and may collapse.

So Yu Fei had to use spiritual energy as his eyes to explore the way the stones here overlap each other, and then try his best to ensure that the stones above are supported while digging, so that a stable and safe passage can be constructed.

Of course, this is not easy. On the one hand, the stones here are thousands of years old, and the stones themselves are no longer strong under the erosion of time. On the other hand, the pressure from above is too great. The pyramids are made of stones.

It is a large and terrifying building, otherwise it would not be considered a miracle, so the pressure from the top on the stones below becomes greater as it goes down.

When you are not digging, the stone sticks to the stone and seems to be a whole, which is relatively stable. Once you destroy the wholeness, the stress-bearing structure changes and collapse is just a matter of time.

Yu Fei carefully explored the structures of all the surrounding stones, and was constantly calculating in his brain. He needed to plan all the routes before he could take action.

This is not a simple matter, it requires strong three-dimensional thinking ability and calculation of force analysis.

After more than ten minutes, Yu Fei finally roughly determined a route and direction. However, the calculation results showed that it was not a straight line of digging, but the safest way of digging. Therefore, it was equivalent to the length of the excavation that he had to dig, which increased to more than forty years.

It’s rice.

However, Yu Fei didn't care about so much anymore. He could only start work quickly. However, when he started work, he was already highly nervous. Once he found signs of possible collapse, he needed to react immediately and escape upwards. He might have reacted earlier.

Coming here for half a second means whether he can leave here alive.

Just like this, he kept moving forward with tense nerves. The safe route calculated by Yu Fei was not a straight line. It might be to break a stone forward and break the stone in front and side, and then take out the gravel inside and use it from the angle.

Drill through the gap. Once a collapse occurs along this route, it will be very difficult to escape.

Yu Fei dug very carefully. Every time a stone was broken, he would step back first, observing while backing up. If he found that there were no signs of collapse, he would step forward to clean up the gravel, and then proceed to the next step.

Even with Yu Fei's psychological quality, he was sweating constantly on his forehead, because every broken stone seemed to be a provocation at the gate of hell. If he made one mistake, he would walk in and never come out again.

Just when Yu Fei was slowly moving forward, doing the last and most dangerous thing, in the underground altar, the giant mummy finally reached the limit. In order to resist the mysterious power, the giant mummy fell down, and his body continued to

Trembling, his consciousness fell into blurs again and again.

The other mummies also noticed something strange, and they all gathered around. However, no matter how they tried to send messages and asked, the giant mummy did not respond, and the other ordinary mummies did not know what to do.

They are creatures that should not belong to the earth. They are just a ball of soul energy. They are even immortal existences, so they will never get sick. And they have never encountered such a situation at all. Other mummies are really

I don't know what the situation is and how to deal with and help the giant mummy.

lizard

Lizard was also frightened. Even though this guy was very rebellious, as if he didn't recognize any of his relatives except Yu Fei, but the giant mummy was the earliest mummy in the pyramid, and they were the earliest companions. Now the giant mummy has never appeared in thousands of years.

When a strange situation occurred, the lizard stopped running away and came closer to take a look.

But they just watched and couldn't help the giant mummy at all.

Suddenly, the giant mummy lay down completely, as if dead, and there was no movement at all.

The other mummies not only spent a year trying to wake up through sound transmission, but found that it was of no use. They just couldn't make expressions and shout, otherwise the cries would probably have resounded throughout the pyramid.

One minute... two minutes... five minutes later, the giant mummy finally moved!

The other mummies were very excited. To be honest, they actually thought about death, because they are all the products of death. What they saw the most was death. The most common interactions with the humans outside were to bring in the dying people.

, and then die here.

So they all thought that the giant mummy was going to die, and their myth of immortality seemed to be broken. They were all a little panicked, because they had never thought that their inexplicable death without their will was a

what's the situation.

Fortunately, the giant mummy didn't seem to be dead, and the other mummies breathed a sigh of relief.

Just when they were in a daze, the giant mummy got up and suddenly began to transmit messages to all the mummies collectively.

"Yu Fei is destroying the pyramid, hurry up and stop him! Stop him at all costs!"

The giant mummy transmits the same message to all other mummies.

The giant mummy had just finished transmitting thoughts, and the other mummies were shocked, and then rushed out together without hesitation, because the moment they knew the news, the mysterious energy came into play, and they would protect the pyramid at all costs.

, kill the saboteur.

Even the lizards rushed out together. After all, the lizards were the earliest aborigines here. Other mummies would be controlled by mysterious energy, and the lizards were certainly no exception.

Thousands of mummies rushed out of the ground regardless of the cost. All the simulated items Yu Fei gave them along the way were knocked down and trampled to pieces. They finally revealed their crazy side like wild beasts that humans least want to see.

Soon they rushed to the place where Yu Fei had set up obstacles. Behind the obstacles was the entrance of the hole dug by Yu Fei. If these obstacles faced ordinary people, they could still block them for a while, but with so many mummies, no matter the cost, the obstacles would only

After blocking them for two minutes, they were completely destroyed or moved away, and then the mummies rushed to the entrance of the cave.

Then they saw the destroyed boulder. They didn't care about the situation or structure inside, and then they started to jump into it crazily. However, it was not a straight line down here. Occasionally, they needed to turn. Suddenly, the mummies who jumped in front of them started to bump into each other.

Fortunately, I didn't feel any pain. I managed to stabilize my body. The mummy behind me fell down again and knocked over the mummy in front of me.

Their madness can increase their combat effectiveness, but under such circumstances, the efficiency becomes very low. After being frightened, dozens of mummies jumped down, and the passage was blocked. Some of the mummies below were talking to each other at the corner.

They were crowded together, and they all wanted to scare Yu Fei to pieces, but with each other's obstruction, no one could get out of trouble quickly.

The mummy behind saw that the passage was blocked and wanted to continue rushing down, so the speed became slower due to the crowd.
