Chapter 614 Discovery Underwater

There are also many lighting modes for the combat wristband. In addition to the type and brightness of the light, there are also many options for the irradiation range.

This is similar to the lighting mode of a drone. Yu Yishan has also become familiar with this convenient mode of changing the light at will. He adjusted the light to a fan-shaped irradiation mode so that the light points to the bottom of the water without leaking to the water surface.

With enough light sources, the field of vision immediately widened.

Yu Yishan discovered that the bottom of this pool is not very deep, at most about ten meters.

He plunged down and was soon on the bottom.

There are no pebbles or the like at the bottom of the water, only some fine sand and mud, which can cause a little turbidity when stepped on.Under the shallow sand is a hard rocky ground, but more rocks are still exposed, which looks high and low, potholes, and very uneven.

Yu Yishan turned on the lights again and began to observe the surrounding environment.

The pool is not that big, but the bottom is wider than the water surface, it looks like an upside-down rice bowl, but the bowl is tattered and uneven.The temperature at the bottom of the water is only a few degrees, which is already very cold, but Yu Yishan can bear it even without protective clothing.Even if it is an ordinary person, if he is used to winter swimming, he can handle it after a short stay here.

This environment is not suitable for ordinary tourists to enter the water.

The water temperature is so low, there must be a reason, Yu Yishan began to search around.

The bottom of the water is still very clear, there are no creatures like fish and shrimp, and the light of the combat wristband has a strong penetrating power, and the visibility under this water is very high.Yu Yishan looked around for a while, but he didn't seem to see anything unusual.So he swam to the edge of the bottom and started circling the bottom, looking for the source of the pool.

After going around half a circle, Yu Yishan found that the ground at the bottom of the water was actually sloped.But because the ground is very uneven, it is not obvious in a small area.

He discovered the difference in height through the change of water temperature and the data reminder of the combat wristband.

So he curiously moved towards the lower ground, and soon approached the edge of the bottom of the pool.But he found that this edge was not the real edge, and there was actually a crack-like channel at the bottom of the pool.

This passage seems to be under the rocky cliff, and when Yu Yishan is close to the entrance of the passage, he can still feel the weak surge of water, which seems to be the source of groundwater.

The temperature of the water at the entrance of the passage is lower, and it is difficult for the light of this temperature difference to feel through his palm.But through the temperature sensing of the combat wristband, it can be found that the temperature in the passage is slightly lower by one tenth of a degree, which also proves that the source of the pool is likely to be the groundwater flowing from here.

The passage was flat, and the entrance was wide enough for several people to sneak in at the same time. Yu Yishan swam into the passage with great interest without hesitation.

Then it slopes all the way down, the passage is always relatively spacious, and the walls are flat, and there are no other forks, just like a tunnel dug out by humans.

Following this passage, Yu Yishan dived more than 100 meters in one breath, and suddenly passed through the entrance of the cave, and his eyes suddenly opened up.

This place seemed to be another huge space. Yu Yishan turned on the lights again, turning himself into a huge bright light bulb. Then, he found that he was indeed in a space that looked like a hall.

Through the strong lights, the surrounding scenery quickly became clear.

This hall-like space has an area of ​​about a thousand square meters and a height of twenty to thirty meters. It looks like a regular circle, and the dome is also round with a smooth arc.This structure is a bit like some kind of venue, such as a stadium, arena, or theater, except that there are no stands around it.

This is still a rock structure. Yu Yishan checked around and found that the surface of these rocks, including the ground, is also very flat, as if it has been artificially repaired.

However, there were no traces of tools digging on these rocky floors and walls. Yu Yishan thought this might be the reason for water erosion.Nature has always liked to erase traces of human existence, and it doesn't take much effort to erase this edge.

Anyway, Yu Yishan felt that it was basically impossible for such a neat cave to be formed naturally.

So he continued to check around the hall, and after swimming around, he found a few more downward passages, which were still the same flat passages as before, and if you didn't look carefully, it was just a gap.The passage is still wide enough to easily accommodate multiple people sneaking in parallel.

Other than that, the entire hall was empty, with no artificial buildings, no extra rocks, not even a single fish.

This time, even if Yu Yishan was beaten to death, he would not believe that this place was formed naturally.Naturally, it is impossible to create several identical passages, and the inner walls of these passages are all equally neat.This must have been excavated by hand, and it was submerged in water for unknown reasons.

Looking at the newly discovered passages, Yu Yishan was a little embarrassed.

This kind of man-made underground space must continue to be explored. No matter whether there are treasures or dangers underneath, it is necessary for him to find out in advance.This is a place that will be developed into a tourist attraction. If there is danger below, isolation and blocking measures must be established at the entrance of the passage.

If there is no danger below, then this place can be developed into an adventure place for diving enthusiasts. Although the water temperature here is close to zero, it will still be attractive to many people.

If there is only archaeological value below, then the key locations must also be protected.

Yu Yishan looked at the diving record on his wrist. He has dived to a depth of nearly 150 meters.The highest human diving record is more than 300 meters. For professional divers, the depth of more than 100 meters is just the beginning.Therefore, he must continue to explore, at least to the limit that ordinary people can reach.

However, today's time is not enough.

After going down these passages, I don't know how far I have to dive, and whether there is any fork in the road after diving down.It will definitely take a lot of time to explore all these passages.

He can only find another time when there is enough time to complete the work.

The personal combat terminal can record and draw a holographic map, and you don't have to worry about getting lost if you continue to explore the passage.Moreover, there are basically no forks in the route I have traveled so far, and it is all the way to the end, and I will not lose my way when I return.

Yu Yishan began to return.

Due to wearing protective clothing, there is no need to consider decompression during the ascent process, which saves a lot of time, and he can just swim back directly.

Not long after, Yu Yishan returned to the surface of the water, and was about to greet the little rabbit to go ashore together, but found that the little rabbit was gone.
