The lake is like a funnel, the deepest in the center. Her air conditioner can't change the water pressure.

Zixu feels a bit of a struggle. She has exceeded the 100 meter depth limit set by a professional diver.

Tian Tian said, "it's still very deep below. Go back first."

Zixu nodded, here can only rely on the night pearl illumination, also can't see anything, are ordinary sea creatures.

She turned and went upstream, but she didn't see a flash of light under the water.

She had just floated up about two meters, and a lot of bubbles came out under the water. Before she could react, her waist tightened and something caught her.

She looked down and saw one tentacle curling up her body. She took out a dagger to chop, but was knocked off by another tentacle.

Then a huge pull pulled her into the abyss.

Fortunately, the tentacles caught her whole body, otherwise the water pressure alone would have killed her.

I don't know how long after that, Zixu fell to the ground.

The night pearl on her waist can only light up a small circle around her. It is obvious that she has entered a cave without water at the bottom of the sea.

Tian Tian said: "last time I changed some big night pearl, you take it out."

Zixu quickly found the big night pearl and took it out to expand the field of vision.

In the distance lies a huge octopus, which is rolling violently, seems to be very painful.

Zixu approached and saw his knife stabbed in the octopus's head. The octopus's tentacles were thick and full, so he could get the knife out.

"Shall I go and mend my knife?"

Tian Tian said: "I don't know how many meters I've dived. If you kill it by mending your knife, you may not be able to go back."

Zixu hesitated. The octopus found her, threw out his tentacles and rolled her up and put it on his head.

"It wants me to help?"

Tian Tian said, "it seems that it may be the last fight. Are you afraid to kill it directly?"

Zixu: "it's just Do Octopus have such a high IQ?

Anyway, Zixu went to put the knife away.

The octopus settled down.

Zixu is hesitating to communicate with the octopus. The octopus grabs the big night pearl on the ground with his tentacles, and seems to be very interested in it.

She took the opportunity to look at the cave.

Behind the lake are the cliffs and mountains. Are they inside the mountain?

We can't do that now. We have to find a way out.

She wasn't stupid enough to talk to the octopus.

Farmland is also at a loss.

Zixu saw the octopus playing with the night pearl, so he took the opportunity to go deep into the cave.

It's wet here. There's flowing water on the ground, which flows into the pool where the octopus comes out.

"The water seems to be fresh water," he said

Zixu looked at it and tasted it again: "it's fresh water."

"Follow the water and have a look."

"Good!"

Zixu follows the current, and the more it goes, the wider the current is.

She didn't think it was enough fresh water to make the lake fresh water.

Tian Tian suddenly laughed.

Zixu was scared: "what nerve do you have?"

"I just think of one thing. The water is rich in minerals, but it was the natural mineral water that our time dreamed of," he said

Zixu skimmed his lips: "if it didn't create so much pollution, all fresh water would be natural mineral water."

"Yes, but human progress inevitably leads to pollution."

Zixu shook his head: "environmental protection is still not good. If you can realize environmental protection at the beginning, you won't be mad when you find it."

Tian Tian said with a smile: "who makes mankind always covet the present enjoyment? As a result, it has harmed future generations. "

Zixu is speechless, which can't be refuted.

If one day she can have a higher power, then we must vigorously promote environmental protection.

In fact, she has been doing this all the time. For example, cutting trees in mountain forests always needs to replant corresponding seedlings.

I only hope that future generations can inherit it.

The road got narrower and narrower. At last, I saw a round hole where the water came out.

Zixu goes in. The hole is slanting upward.

If you climb out, will you appear somewhere on the mountain?

She didn't care much about it, and went on.

Thanks to the shoes I changed before, I can walk steadily on the slippery ground.

At the back, the passage was straight up and down. She could only support the wall of the cave with her limbs.

It's just the impact of the current, it's very difficult to walk.

When she reached the top, she did not see the way out, but came to a new cave.

She continued to follow the current.

There are many stalactites in the cave. It's just like rain.

The amount of water gradually changed from drizzle to rainstorm.Zixu can only keep going under pressure.

I don't know how long she went. She finally saw the long lost sunshine.

It was a big hole in the bowl. She opened it with a hoe and went out.

Outside is a valley with a big waterfall. A branch of the waterfall flows to the cave over there.

At the bottom of the canyon is a pool, and above the cliff there is a silvery object.

"Wow Is it a UFO? "

"I'll go up and have a look," he said It goes into the ferret puppet and swishes up.

Zixu looks at the cliff and climbs with shoes.

She didn't know how big it was until she came to the silver object.

It's as big as the palace of the capital. It doesn't have windows, but there's a hole. The water comes out of the hole.

Zixu from the edge of the hole drilled in, it is very black.

After finding the source of water, she sighed: "well developed technology, can actually produce a continuous stream of fresh water."

Tian Tian ran over and said, "the shark over there is talking."

"What do you say?"

"They want to see this thing and trade scales for it."

"Yes." She's going to explore it anyway.

As Zixu inspected the machine that made fresh water, a shark said, "isn't this the villain who turns the sea water into fresh water?"

"Yes, it's because of this that the sea water here becomes fresh water."

"Unfortunately, we can't destroy it."

"Hateful thing."

Zixu thought: "farmland, can you let them take this kind of thing as an exchange?"

Tian Tian asked, "what do you want this for?"

"If you can make fresh water, you can put it in those desertification areas."

"Oh, let me ask."

Soon, Tian Tian replied, "they would like to, but I have made a deal that they need to compensate with their valuable things."

"Compensation? What kind of compensation? "

"It's reward. We're trying to help them. Do we have to pay?"

Zixu nodded: "well done." Tian Tian deserves to be a traitor.

As for the transaction, Zixu doesn't care about it. She doesn't understand what makes fresh water.

After exploring it for a while, I found some information.

After translation, Zixu probably understood the original intention of making this thing.
