Qin Feng rowed his oars alone on the surface of the lake without hurrying forward, this lake area is not very large, but it is not isolated, through a small mountain stream can be connected to a larger lake area outside the base, it is one of the few passages to the outside world here, and it is the only waterway.

Qin Feng also considered setting up his military camp here, on the one hand, the transportation here is convenient, if there is a ship that can easily lead from here to the outside world, and then before obtaining military power, this place can advance or retreat.

At the same time, the aquatic products here are very abundant, which can well alleviate the supply of food, and can also provide meat protein, which is a rare treasure.

It's just that opportunities are also accompanied by dangers, and there may be unknown creatures passing through here, whether underwater or on the water, they need to be on guard at all times, this is one of the reasons why Qin Feng sent a message to the military headquarters to be stationed here, and no one has anything to say.

With Qin Feng's physical strength, although the boat was rowed by hand, it was still very fast, and it almost reached the center of the lake within the base in less than ten minutes, where the water surface fluctuated slightly with the breeze, and the abundant water vapor gave the night a hazy color.

Qin Feng could feel that the cathode energy here was much larger than that on the ground, and the Heaven and Earth Yuan Qi in the air was also very strong towards the cathode.

"It's here, yes." Qin Feng said to himself while rowing the oars

The boat circled around the area, but found nothing of note.

"Qin Feng, go underwater and take a look, it's estimated that it's in the water." When Qin Feng felt the high point of the cathode energy, Mo Yue suggested in his mind.

"Well, Sister Mo Yue, you and I have a piece." Qin Feng couldn't help but nodded, and then recalled the general from his mind, and began to perform the technique, Xuan Ao's mantra was not long plus a few gestures, and a faint brilliance flashed from Qin Feng's body.

Qin Feng cast a most basic small spell "Water Avoidance Technique" just now, after this spell was blessed on himself, it could make Qin Feng not get wet on his body before his energy was exhausted, so that he could easily move underwater.

At the same time, Qin Feng will also turn his breathing into internal breathing, naturally he does not need to breathe air, and the time he stays below is also determined by his own ability.

After doing all this, Qin Feng stood next to the boat and jumped into the water with a pop, his posture into the water was very beautiful, there was hardly much splashing, and all of a sudden only a lonely boat floated on the water.

As soon as Qin Feng entered the water, he was no different from a dexterous big fish, and his diving speed was also very fast, and he swam more than ten meters away with a stroke of his hands and feet, which was extremely light.

"Yes, this is it, the cathode energy is getting more and more intense." Qin Feng said to Mo Yue in his heart.

"Yes, it seems that you have a high probability of gaining this time, and you will definitely not run in vain." Mo Yue looked at Qin Feng with encouragement.

Although it was not the first time for Qin Feng to dive, he had done this kind of underwater diving mission several times, and he had done a lot of training, but it was the first time he had swam in the water like this, Qin Feng dived down, but the doubts in his heart were getting bigger and bigger.

"Sister Mo Yue, the bottom of the lake here seems to have become deeper!" Qin Feng estimated the depth of his dive and came up with a very strange result.

According to the information Qin Feng found, the average depth of the lake here is only more than 20 meters, and the deepest depth is not more than 30 meters, but now Qin Feng is already in the underwater world of 50 meters, but he has not yet reached the end.

Although Qin Feng can see in the dark, it is not absolutely dark, even a trace of bright light reflection can allow him to see everything in front of him clearly, but under the water at this depth, it is already pitch black, Qin Feng does not bring any lighting equipment, and now it is all relying on the role of divine consciousness, but here Qin Feng's divine sense exploration range has been compressed again, only a pitiful twenty meters.

After probing down, Qin Feng didn't feel that he had touched the bottom, and he didn't have doubts in his heart.

You must know that lakes with a depth of more than 70 meters must be on the list inland, and it is impossible to be so obscure.

Qin Feng patiently dived down again for a distance, and finally felt the terrain under the water, which was already seventy meters underwater.

"It's 90 meters, and I don't know if it's the deepest, it's really incredible." Qin Feng sighed more and more in his heart, and the magic of nature was amazing.

"Qin Feng, don't be careless, this is definitely not the terrain formed a long time ago, you can know if you feel it carefully." Mo Yue has seen many big scenes, and this situation will not make her sigh in the slightest.

Sure enough, after Qin Feng went downstream again, he felt that there were some artificial creations nearby, which were several statues, and at the same time, looking at the age, they were built in the past few decades.

At this time, Qin Feng remembered a previous news, this lake was not so big a few decades ago, at that time, for some reason, the water in the lake skyrocketed, which directly caused a small island in the lake to be submerged, sank into the water, and never appeared again, but according to the report at the time, the water surface just looked at the submerged island.

The incident was said to have caused a sensation at first, but then the government suppressed the news for some reason, and all the reports changed overnight, saying that it was a news fraud incident, and finally it was closed.

If Qin Feng hadn't taken the opportunity to check some confidential documents in the base a few days ago, he wouldn't have known that there was such a strange thing happening here.

But looking at what happened now, it is even more so than it was decades ago.

What had sunk to the surface of the water actually sank again, but this time the surface of the lake was not recorded as being expanded, so it was only possible that the bottom of the lake sank.

And it's not a short distance, you must know that 90 meters is the height of a 30-story high-rise building, and it is simply incomprehensible that such a large ground movement has not occurred any recorded seismic records.

The big problem here made Qin Feng more and more confused.

"Let's go, keep diving, and only when we get to the bottom will you know what's going on. What is known now is that there has been a great change here, but the scope of its impact is really small, not even the shore has been changed in the slightest, and there must be a deeper reason for this great change. Mo Yue also showed a certain interest at this time.

Indeed, as Mo Yue said,Until the end of the world,The school park by the lake has been established for more than ten years,No problems have been found,The lake area here is also a place where the school park carries out some water sports,But there is no suspicious report,It can be seen that all this is definitely happening after the end of the world。
