Going down to the bottom of the cave were Su Ze, Wang Zhi and Yuan Ye. The three of them are the most qualified in military affairs among this group of people. Needless to say, Su Zhi is a retired military officer, and now he is engaged in smuggling on the Sino-Russian border, and there has never been a shortage of fire. Yuan Ye is an active-duty officer. Although it is not a special force or scout, it is above average.

They are now all wearing full expedition gear. Everyone has an eighty-one style, wears a riot-proof helmet with a headlamp, wears a stab-proof suit, wears stab-proof boots under his feet, and hangs a strong first and a flashlight on the barrel. There are also pistols, grenades, flashbangs. as well as sabers, military stabs and other cold weapons. And then each person brought one. Gas masks, as well as matching small oxygen cylinders, can contain enough oxygen for a person to breathe. Half an hour.

In addition to the weapons, there were also a lot of detection instruments, in addition to the indispensable Reiki meter, "there was also a radiation meter, the Geiger counter, which was used to measure the radiation in the cave. And then there's the air analyzer, which is an essential thing for caving. Because there is a high probability of poisonous or asphyxiating gases in the cave. Or lack of gas and so on.

In the past, explorers carried a cage containing a guinea pig or bird for early warning of poisonous or asphyxiating gases. Now with this air analyzer, it is much more convenient, and the accuracy of this is much more accurate than that of animal warnings.

The three of them climbed down the rope ladder from the entrance of the cave, which was a sinkhole more than ten meters deep, and after reaching the bottom of the pit, there was a passage that extended diagonally down.

"Go on, I used the eye of heaven to detect just now, there is only one passage here, and there is a large cave at the end," Su Xue said to the two.

"Well, nothing, right? Wang Zhi asked.

Su Ze shook his head: "Except for some mice and insects, there is nothing else."

Although it is not a secret, it is related to human life, and Su Xue doesn't want to make any extraneous things now. So even for these Daoists who have already had a showdown, Su Xue kept it a secret for the time being. As for his detection ability, his explanation was that he had inadvertently cultivated a Heavenly Eye Ability. This kind of cultivation and cultivation of supernatural abilities is not uncommon in the cultivation circle, so everyone has no reaction except for a few words of envy.

Continuing from this passage, there are several more turns. The passage is all sloping downward, and it seems to be deep underground.

After three turns and two turns, Shimen's eyes lit up and he came to the large cave that Su Xue said.

The three of them took a strong light torch and shone around, observing the surrounding situation.

"Huh, there is such a big karst cave here, it's strange, this place shouldn't belong to the karst terrain," he looked at for a while. Yuan Ye said with some surprise.

Although it was already clear through the gloom just now that this was a big cave, it was because of the light. I didn't see it too clearly. Yin Sha does have dark vision, but it is only more sensitive to objects with heat sources, and in this environment, dark vision is not very clear. Besides, the infrared imaging picture always looks blurry. Su Ze has not been very uncomfortable.

"That's right, it does look like a karst landform here," Su Ze also nodded, agreeing. This large hole is really. It's a cave.

Karst landforms, also known as karst landforms. It is a general term for the surface and substructure formed by the dissolution of soluble rocks by water with dissolving power. The cave is one of its unique terrains.

The cave in front of you is a typical cave. There are various types of rocks inside. Such as stalagmites, stone pillars, stone stalactites, stone curtains, etc. These rocks are karst deposits, and under the magic of nature, many strange landscapes have been formed.

The more the three of them looked, the more surprised they became, because they were looking for the source of spiritual energy everywhere, there were not a few scenic spots they had visited, among which the karst cave was often visited, and the karst cave landscape they had seen was not a hundred but eighty. However, the karst cave landscape here is obviously the essence of the essence, and all kinds of strange and colorful karst caves are piled up in the landform, forming an extremely magnificent cave wonder.

On the opposite side of them, there is a large stone mantle, in the form of sheets, and with curved flow lines. The height is tens of meters, which is very spectacular. The mantle is the product of the gradual deposition of calcium carbonate during the film-like diffuse flow of karst water along the cave wall. In addition, the strange stones of various forms resemble people and objects, and the forms are realistic and lifelike, like an underground gallery made of stones, which is really full of eyes.

There are also many peculiar landscapes, some like lotus flowers blooming, some like tree branches stretching, and some stone grapes, stone corals, etc. It can be called an "underground art palace." ”

Wang Zhi swallowed his saliva and couldn't help but sigh: "Damn." It looks better than the Yellow Dragon Cave, and if it is opened here, it is definitely a tourist resort

The cave was quite large, at least a square kilometer just as far as they could see. I haven't seen the edge of this territory yet. Winter is strange, what kind of place is the public. How can there be a big cave? ”

The three of them looked at each other, all a little confused. They are now in the eastern region of Sudan. This is a tropical desert terrain, certainly not a karst landscape.

"Could it be because this is the Spirit Cave?" Wang Zhi speculated.

"Probably," Su Ze and Motoji both replied vaguely.

For the knowledge of geographical structure, these students are only a little better than Xiaobai, and they are probably at the level of Lao Bai. This is also because cultivators are indispensable to find "treasure land". "I had to learn a little more.

That's not what they're concerned about right now, though. They are cultivators, not geologists.

Su Ze has now released all the evil spirits and made a big deal of extortion here.

So far, Su Xue has refined a total of flying yin, among which the old one has been taken away by Uncle Si Ming.

According to Su Ze's observation, Si ordered to sinister this thing. The main purpose is to help yourself with digestion. And then there's the usual thing to take things or something. Because although the power of the division is strong, it has no substance, and it is difficult to directly interfere with matter. In addition to things like "Very good Magic Pills." Such strange things, common items, but it can't be used directly.

For example, the laptop that it uses every day. In the past, although it knew how to use it and knew the steps to operate, it could not use the mouse and keyboard. So you can't do it yourself. I can only ask Su Ze and Jin Guang to help.

Later, this guy now realized that Yin Sha could directly act on the real thing, so he began to operate it himself, so he was exempted from the task of being a scholar of Jinguang. Of course, Su Ze's yin evil also lost five more because of this, and they all went to do chores for Uncle Si Ming.

Therefore, now it is left for personal use, and the common couple is only evil. Among them, there are 3 of the third order, the mouth of the second order, and 3 of the first order.

Because of the shadowy pathfinder, there is no need to worry about being suddenly attacked by some dangerous creatures, so the three of them don't have to worry too much.

However, even if there is no warning of yin evil, don't worry, Wang Zhi and Yuan Ye, the two guys, both have immortal weapons on their bodies. Although with their cultivation, they can't even wield one-thousandth of the power of the immortal weapon, but the basic early warning function can still be used.

In particular, Wang Zhi's Tai Sui Broken Army Armor "is the natal magic weapon of his ancestor, which is connected to his bloodline, and is even more protective of him, lest this bloodline descendant who was hard to find accidentally hang up."

Now, this is the case. Tai Sui in order to prevent just in case. It came down from the belly of Wang Zhi, who usually lived in the hermitage, and transferred it to his shoulder, turning into a soft one-piece shoulder pad.

However, what is more disgusting is that this "shoulder pad." There are also a lot of tentacles stretched out on it.

And on the tip of each tentacle, there is an eye. Wang Zhi's current appearance looks very numb, if people who don't know see it, I'm afraid they will think that they have touched a tentacle monster.

Su Ze couldn't help but curse in his heart: I remember that Wang Mang should be a more elegant person, how could he come up with such a disgusting natal magic weapon?

After a few hours of exploration, Su Xue and the three of them finally completed the preliminary exploration of this large karst cave. In fact, it is to wrap around the side wall of this cave and determine the size of this cave.

According to their field investigation and measurements, this cave is a relatively regular ovoid shape, about 3.5 kilometers long, about 2.5 kilometers wide, with a total area of about 8 square kilometers. The height of the caves is uneven, the highest is about close to the small of the hurry, and the lowest is less than the old rice.

Due to the karst topography, there are many stone pillars connected between the ground and the top, which also play a supporting role, but there is no need to collapse. According to their estimates, the top of the cave fell about a meter from the ground.

As for the passage, the current one is the passage where Su chose them to come, and there are stone walls all around.

The measurement results of various instruments are also very satisfactory, and the radiation, air composition and other factors are in the normal range, or even better. In particular, the aura of their most relationship is unbelievably rich.

Yuan Ye has been measuring all the way, and now the concentration of aura here, the lowest data is also above the old O. The highest middle zone, the value even broke through!

What is this concept?

Take the Heavenly Dao Blessed Land, which is currently the most familiar in the domestic cultivation circle, the position with the highest concentration of spiritual energy is not enough. It's an astonishing blade, six times as big as that over there.

If this place were known to the cultivators in the country, I don't know how much shock it would cause. Definitely sharpen your head and drill here.

When they got here, the time was almost up, and Su Xue and the others also returned to the ground and informed the Daoists of the results of the investigation just now.
