Chapter 281 Changes at the Bottom of the Lake Copper Mine!

"Ke Ke, you are waiting for me by the lake, I'll go down and have a look."

"Hey!" Ke Ke responded, jumped off his shoulders, and lay down on a stone by the lake.

At this time, the lake was very calm, and the breeze blew by, causing faint ripples on the surface of the lake.

There were no swimming fish in the lake anymore, and even the original lotus, lotus root, reed and other plants by the lake had all withered at this time, and the whole lake presented an extremely bleak scene.

I don't know if this lake will be directly frozen tomorrow.

The water in the lake was very clear. Xu Xin looked at the center of the lake. The bottomless center of the lake was still pitch black, like a dead lake. Looking at it made people feel frightened.

Xu Xin took out a water plant (blue), ate it and gained the ability to breathe underwater, and ate the red berry big (blue) that allowed him to see things clearly in the dark, took a deep breath, plunged into the lake.

The cold lake water instantly soaked his whole body, making him tremble.

This lake is so icy! It's already close to zero!

The scale armor is not an airtight suit, and water seeps in from the gaps in the scale armor, making him feel a chill all over his body.

so cold!

The scale armor suit can't stop the cold in the water!

This has to be sped up! Otherwise, with this temperature, it won't take long for his hands and feet to freeze and become numb.

Xu Xin opened her eyes and looked at the scene in the shallow water area.

In this lake, there is really not a single fish left, and even the ordinary aquatic plants at the bottom of the lake have disappeared, leaving only gravel and gravel covering the bottom of the lake.

Compared with the previous lake, the lake at this time really makes people feel extremely bleak.

Without stopping, Xu Xin continued to swim towards the center of the lake.

Soon, after a few seconds, he reached the edge of the huge hole in the middle of the lake.

Huh?

Xu Xin sensed something was wrong.

The bottomless hole in the middle of the lake, how does it feel... enlarged?

The last time he went down to the lake, the place where the edge of the deep pit at the bottom of the lake dropped suddenly was about 30 meters away from the edge of the lake, that is to say, the range of the shallow water area was about 30 meters.

but now……

Seeing the huge crater in the center of the lake that suddenly appeared in front of him, Xu Xin turned around and looked behind him.

The distance from here to the shore is only twenty meters at most... No, it's less than twenty meters!

... Will the giant hole in the center of the lake expand by itself? !

Xu Xin's heart suddenly tightened.

What's happening here?

After experiencing the giant head salt mine incident, he is very sensitive to this kind of terrain that can be changed by himself.

Could this giant hole be alive?

Behemoth's mouth?

Mom... I'm a little afraid to download it...

No, no, no...it shouldn't be possible...

It's just a hole. Judging from its appearance, it has nothing to do with the mouth, and it's completely different from the giant's head.

but……

Xu Xin pursed her lips. This lake is really dangerous.

Although he chose to plant a tree house here at the beginning, although it brought him a lot of convenience, the dangers came one after another.

If this huge hole can really continue to expand...

His tree house is only less than 200 meters away from the lake, which is very close. If there is a problem with the lake, his tree house may not be able to escape.

Could it be that he remembered wrongly?

No, this distance has definitely shortened, and the giant hole has indeed expanded!

Forget it, let's forget about this, let's talk about it after finishing what we have to do, Ke Ke said that there is no danger in the cave, Xu Xin still believes it.

He stared intently at the big hole in the abyss.

At a depth of about twenty meters from the water surface, blue-grade aquatic plants grew again, floating on the cave wall with the current.

It can be seen from the direction of the blowing grass that the water in the huge cave in the center of the lake is slowly rotating in a clockwise direction, like a huge whirlpool.

However, because of the slow speed, if there is no movement of aquatic plants, it is impossible to see that the water is flowing with the naked eye.

At a depth of about 40 meters, the dark green ores were still on the cave wall.

However, unlike the last time, none of the weird, aggressive-looking big fish that were swimming at a depth of fifty or sixty meters before could be seen and disappeared completely.

The blue-grade fish maw he ate was obtained from this kind of fish, and it also gave him a stronger ability to resist water pressure, so he was able to dig out those green metal ores now.

Xu Xin carefully observed the rock wall below. He was afraid that these fish, which were very similar to the surrounding rock walls, were sticking to the cave wall at this time and blending with the cave wall, so he didn't notice it.

After observing for a long time, he finally confirmed that there was indeed no such big fish in the cave at this time.

After confirming that there was no danger in the cave, Xu Xin continued to sink slowly, reaching a depth of about 20 meters, and harvested blue-grade aquatic plants again. This time, he obtained 14 plants, enriching his inventory.

Continued to sink, and soon, Xu Xin was close to those green-looking ores.

Most of these ores are green grade, only a few sporadic ones are shining with blue light.

Xu Xin already felt something abnormal in his body, his body and ears couldn't bear the water pressure here.

Forty meters...

This is probably his limit.

Compared with Brother Qin Yunlong who was able to dive below 100 meters for exploration a long time ago, his diving ability is really worrying.

But it is enough, at least these ores can be collected.

After connecting with the other side, the bottomless underwater giant cave was left to the two of them to explore.

Xu Xin glanced down, the pitch-black abyss, the bottomless depth of the water gave him a chill, and he quickly looked away.

scary!

This is really deep-sea phobia.

He swam to the edge of the rock wall, stretched out his hand towards the green ore, and touched the ore.

[Copper Ore (Green): Metal ore that can be smelted into copper blocks in a furnace. It is extremely conductive and is the basic material for making electrical appliances. 】

really!

coming!

Copper ore!

His guess was right! It's copper ore!

Copper ore that can make electrical appliances!

It turned out that the copper ore was hidden in such a deep place, no wonder Li Wenxi even found the gold mine, but could not find the copper mine.

It turns out that the copper mine is in deep water!

However... Qin Yunlong and Qin Yunhu brothers seem to have not found the copper mine.

Could it be that he is the only one here?

Forget it, let's not think about this for now, let's collect these copper mines first!

Xu Xin took out the prospector's steel pick, and Li Wenxi gave him hers last time.

Xu Xin kept holding on to the rock wall with one hand, and with the other hand, he swung the pickaxe and chiseled at the ore underwater.

"Crack!" The steel pick chiseled on the ore, but the ore did not change.

The resistance in the water is very high, which greatly weakens the power of the pickaxe.

Xu Xin could only swing the pickaxe again and again, and finally smashed down a piece of ore.

"Crack!"

A whole piece of ore split into five pieces [copper ore]. Xu Xin immediately collected them quickly, but in the end one piece of copper ore fell into a bottomless abyss.

"This..." Xu Xin felt a little uncomfortable. It actually fell one.

There is no good way underwater, he can only collect as much as possible.

"Crack!"

"Crack!"

No copper ore fell down these few times, and Xu Xin collected the copper ore on the rock wall at the fastest speed.

"Crack!"

This time, the triple explosion rate of [Prospector Steel Pickaxe] had an effect. In an instant, fifteen pieces of copper ore appeared, and Xu Xin could only collect them as best he could, but finally three pieces fell.

Shaking his head, he swam to the front of a blue grade ore.

The blue light only accounts for a very small part, and it should only be possible to excavate a piece of blue-grade ore.

Xu Xin swung the pickaxe.

After a dozen times of digging, he finally obtained the first piece of blue-grade copper ore.

And the second and third blocks.

The triple explosion rate is triggered again! And this time it happened to be triggered on blue-level ore!

really not bad!

Putting the blue-grade copper ore into his backpack, Xu Xin stuffed another aquatic plant into his mouth to continue his underwater breathing, and continued digging.

"Crack!" "Crack!" "Crack!"

Soon, there were hundreds of pieces of copper ore in his backpack.

Among them, there are eight blue-grade copper mines.

After that, he mined blue-grade copper ore three more times, and there was another triple explosion rate.

"This prospector steel pickaxe is really good!" Xu Xin was very satisfied with the effect. Not only blue-level copper mines, but also green-level copper mines exploded a lot, which saved him a lot of time.

There are still many green ores that have not been excavated on the cave wall, because this big cave is very big, and there are such ores on the entire circle of the cave wall at a depth of 40 meters. There are a lot of such ores.

But Xu Xin has already decided to go up.

He has been digging for almost an hour, according to his request, Lou Feier should have returned.

Moreover, the water temperature is too low, even though he has been active, he can't bear it anymore.

The most important point, he clearly sensed that something was wrong around him!

The water flow that was rotating slowly around here is now much faster than before!

Now if he doesn't hold onto the cave wall with his hands, he will be carried away by the current!

What's more, what made his hair stand on end the most was that he seemed to hear some kind of deep sound coming from the depths of the cave, like...the roar of a whale.

The voice was faintly visible, but it was still captured by his hearing augmentation.

Deep under the water, there is something!

Or hurry up!

In his backpack, there are now more than five hundred pieces of green-level copper ore and eight pieces of blue-level copper ore. According to the law, five pieces of metal ore can smelt one piece of metal. If they are handed over to Li Wenxi and let her Come to smelt, and you will get more metal blocks in the end.

Should be able to meet the needs.

go up!

Xu Xin began to float up slowly.

The water flow in the cave was really much stronger, taking him to swirl along the cave wall.

In the bottomless hole, low voices kept coming upwards, making Xu Xin's heart hang, clenching his teeth, and looking down from time to time.

Could it be the giant anaconda in the middle of the lake?

Don't draw it out, do you?

No, anacondas should not have vocal organs, right?

However, anacondas can't survive in deep water, and the laws of the original world can't explain anything here. In his opinion, this giant anaconda is almost the same as Jiaolong.

In the end, Xu Xin poked her head out of the water without any risk, breathed a long sigh of relief, and quickly swam towards the nearest lake.

Because of the rotation with the current, his position is already far away from the place where he entered the water.

Xu Xin swam to the shallow water area, swam ashore, and walked around the lake to the original location, where Ke Ke was still waiting.

From a distance, he heard Ke Ke's anxious cry.

"Hey! Hey!" Ke Ke ran back and forth by the lake, yelling at the lake.

Finally, it jumped into the lake by itself, and swam towards the center of the lake with its little paws flapping.

"Ke Ke, I'm already up!" Xu Xin hurried to Ke Ke's direction.

"Huh?" Keke floated on the lake and looked back at Xu Xin, "Huh!"

Xu Xin quickly fished Ke Ke out of the lake. This little guy can float on the water, but his swimming speed is really not flattering.

"Hey! Hey!" Coco rubbed his wet head into Xu Xin's arms, then pointed his little paws at the lake water and yelled twice, then shook his body, and the water on his body shook Xu Xin's face.

It didn't matter to Xu Xin, anyway, he had just come out of the water, so he was covered in water.

"There is danger in the lake..." He understood what Ke Ke meant, looked at the bottomless center of the lake, and swallowed.

It seems that the muffled low voice just now was not his illusion.

And the faster and faster water speed...

Xu Xin was a little scared, it was really a terrifying danger, otherwise Keke wouldn't be so anxious, she jumped into the lake directly, trying to find him.

Let's put the exploration of this lake on hold for now.

The ore in his hand is enough for the time being.

Let professional people do professional things. After connecting with Qin Yunlong and the others, let them come over and explore in the water.

He better stop asking for trouble.
