This cave is only used to connect two huge caves, and sure enough, after we entered, there were no large people here, only vesicles, mountains of vesicles.

The height of dozens of yards is really inconspicuous for a cave hundreds of yards high, but it is better than the accumulation of vesicles like mountains and fields, the volume is small, and the combat power after dozens of hours is not small, and it is still in a steady stream of transportation, and presumably another cave is also in a similar situation, I can't help but shudder, if this mutant body runs out of the mountains, not to mention the assistance of the king, the player is enough to be drowned by these monsters.

I immediately carried the vesicles deeper with another person, and after lowering the vesicles, I found an opportunity for the other person to turn their backs to me and dodge into the vesicle pile.

I took back the transformation card, began to look at the cave, using several auxiliary tools of "Wang Meng", calculated the height of the cave, compared with the height I fell and the depth of the walk, the thickness of the foundation on it was less than ten meters, and I used the map to find my current location, the surface of my area is a high-rise building, how is this supported?

I walked around the pile of vesicles, walked on the edge of the cave, and looked closely, and as expected, there was an upward stone path ahead. When it was first built, if it wasn't for the king's own hands, most of them were karst caves built by labor, and if the support of the top floor was based on physics, if there was no special structure or magic, the thickness of less than ten meters supported dozens of high-rise buildings, even if it did not collapse, it was very dangerous, and this is a place where soldiers are stationed, so naturally there can be no mistakes, so this is also an opportunity for me.

When the trail was built, considering the size of the tools and the safety of labor, the width of the trail was about six people alongside, and there was a parapet wall of more than one meter on the side. When I get a little higher, I won't be noticed even if I stand up straight.

Walking hundreds of yards to the top of the cave, it is not that there is no way out, but that a circular corridor forms at such a high point that there are several more roads as far as the eye can see. When I finally looked closer, I found that the roof of the place was supported by a structure similar to an arch bridge, and the two opposite roads were connected into one arch, and several arches intersected in the center, and the top was supported by a large column, so that if I broke this column, I would greatly destabilize the place.

I walked along the arch bridge to the center, only to find that this pillar is at least tens of meters in diameter, but because it is very close to the surface, the material of this pillar is some sand and gravel loess, which is completely different from the smooth surface similar to granite above and below, and it looks man-made.

According to the experience of "All Beings", and according to the nature of the production staff of "Wang Meng", I picked up the demon sword, pierced straight into the sandstone, and held the hilt of the sword with both hands, and turned the sword body to continuously screw into the sand???

Drill bit???

I can't care so much, when the sword body is all submerged, I hold the hilt of the sword in both hands, and suddenly pull to the right, how can the loose sand and gravel resist my strong force, just a pull, it will destroy the decay and pull out a large piece of sand and gravel, and then split to the left, and there are several pieces of sand and gravel, the climbing claw of the right hand is embedded in the upper layer of sand and gravel, and a large piece of sand and gravel is a large piece of sand and gravel with both hands embedded in the lower layer with climbing claws, and then a large piece of sand and gravel below is broken.

Excavator???

Secretly complained, but the speed of his hand did not decrease, and the climbing claw brought out a large piece of sand and gravel, and after digging like a hole for nearly 2 minutes, the climbing claw "ding" hit the metal-like thing.

I hurriedly dug up the surrounding sand and gravel, only to see a blue diamond-shaped octahedron floating in the air, keeping a distance of about 10 centimeters from the surrounding sand and gravel, and a blue pillar of light rushed up and down, supporting the top and bottom:

[Blue Product Support] (A-rank item)

After injecting energy, the supporting blue crystal can provide a strong support capacity, and the weight and support time of the support are determined by the amount of injected energy.

……

Slowly taking out the aquamarine, nothing happened, but I knew that the stability of the structure had been greatly affected. I cautiously walked back to the edge, walked around the edge, and recorded the path on the map, and at the same time, I also found a small cave with a height of one man, leading directly above the original cave, so that they could do this to save trouble.

This time the bottom is not as good as just now, no longer dormant vesicles, but monsters, test subjects, I almost lay on the ground, crawling forward to the center, carefully digging, for fear that the sound would be too loud or the sand and gravel would fall and expose myself, so this time it took nearly 10 minutes to see the blue crystal.

"Ding! The fifth wave of the offensive will start in 1 minute, so please be prepared. ”

"Ding! The merchant system is now on, and the player can trade with most NPCs, and is not limited to the previous barter, but can also try to barter when bartering is not possible.

"Ding! You are in a special area where monsters will not spawn. ”

The sudden ringing of the bell startled me, and the blue crystal that had just arrived flew out of my hand, and I hurriedly stabilized it, carefully looking below, no one noticed the abnormality.

I took a long breath, climbed back to the edge, and followed a small hole again to the top of the third cave, but this time I found that there were neither vesicles nor research sites below, but a large number of humans and monsters.

From the road down to the ground, I flashed back into the group, and the human subjects around me were confused, and they didn't react to my sudden appearance.

Walking through the small hole, walking through the monsters and the crowd again, but saw that a large group of monsters and some human test subjects had come back in front of the original several forks, and a monster leader led by his face was pale, and shouted angrily: "What a bunch of waste, no brains is no brains, didn't you know the map by heart?" Why only come back so many people! ”

A group of people were struggling, apparently trying to understand what their leader was saying, and some of the squad leaders, who were not very intellectually low, stood up and explained, "We...... They are all patrolled according to a certain route, and they should be ...... You shouldn't be able to go wrong......."

"Then you explain to me what is going on!" The little leader was furious, pointed at the few people who had returned, and yelled.

"I ...... I ......"

I tilted my head over and walked briskly, but what I feared always happened.

"That squad leader, the one with his back to me, said what about you, come here!"
