Zheng Xudong asked Liu Yifei to go back to take a bath first, he went back to the house and took out some small gifts and gave them to the two masters and the two beautiful waiters who came to help them barbecue this time, and gave the two masters a service fee of 2,000 yuan each, and gave the two beautiful waiters a service fee of 1,000 yuan each. and gave each of them a new album of their own. The four of them were very grateful, packed up their things and left the Yan family's garden.

After returning to the room and washing up, he and Liu Yifei had already "fought three hundred rounds" after returning in the afternoon, and Liu Yifei was obviously a little tired, so they just hugged each other and went to sleep.

Liu Yifei soon fell asleep, curled up in Zheng Xudong's arms like a kitten, and arched his head twice into Zheng Xudong's arms from time to time.

Time soon came to the second half of the night, at one o'clock in the morning, Zheng Xudong carefully took away Yifei's hand around his waist from the bed, leaned over and pecked her lips gently, Liu Yifei seemed to have dreamed of something and stretched out his tongue and licked it gently, then turned around with a smile on his face and changed to a more bold posture and continued to sleep.

Zheng Xudong slowly got down to the ground and gently opened the bedroom door to the roof of the villa. He took out the small plane from the space, immersed himself in the plane, appeared in the cockpit of the plane as usual, and flew the plane according to the standard procedure for the take-off of the plane, and flew directly into the sky at the fastest speed, almost vertically on the ground.

"Little love. ”

"I'm here, master. ”

"Start setting the flight coordinates, 53°29'N, 106°41'E, and fly to this position as fast as possible. ”

"Okay, master, have you already thought about it? ”

"Yes, I've decided to go here. ”

"Okay, the flight coordinates have been determined, and it is expected to arrive in twenty minutes. Just when Zheng Xudong was about to change clothes, Xiao Ai said again in his mind: "Master, why don't you go to the place last time to get water?" Can you tell me, I'm so lonely!"

"Xiao Ai, have you evolved again?" asked Zheng Xudong with some surprise.

"I don't know, but I've always wanted to talk to you lately, but I'm afraid of disturbing you. "There are some girls who are coquettish and lazy in Xiao Ai's words.

"It's okay, in the future, as long as there is no one around me, you can take the initiative to talk to me, or at night when I study in my dreams, you can also teach me some knowledge, do you think this is good?"

"Great, master, as long as you talk to me, I won't feel lonely, or you can find something for me to do. Well... Now can I tell me why I didn't go to the last place to get water?"

"No problem! The last place to take water was Hukou Waterfall in the Yellow River, and only half an hour of water intake time has already caused a small area of downstream water to be cut off, and if you take water for a long time, the impact will be even greater, and it may attract investigation by relevant departments. That's just one reason. ”

"And on the other hand, why?"

On the other hand, to put it bluntly, there are some selfish elements. ”

"Selfish?!"

"Yes, little love. Now is the time for irrigation of farmland in the lower reaches of the Yellow River in China, and my long-term intake of water will definitely cause a shortage of water downstream, which will affect this year's agricultural harvest. So I decided not to take water from our country in the future, but to bring disaster to other countries' water sources. Maybe he felt that it was a little bad to use the word "disaster", so Zheng Xudong then said to the little love in his mind: "Actually, you can't use the word disaster, after all, I don't use this water to do illegal things, but to improve the environment of the Gobi." Merely... Well... After all, I am Chinese, and China's water source is very scarce, so it is better to go to some countries where water resources are so abundant that they can be wasted at will. Xiao Ai, this is what I mean by selfishness, or it is more accurate to use national selfishness. ”

"Master, I can't understand your approach for the time being, because the Gamma planet is a unified tribe and there is no distinction between countries, so I actively support you to unify this earth and eliminate the barriers between countries and nations, which is also the ultimate goal of our Gamma System spacecraft to find you to help upgrade the spacecraft. ”

"Xiao Ai, what you said is still too far away from me, maybe I will never be able to finish it, let's talk about the one in front of me first, do you know where I went to get water this time?"

"Of course, you earthlings call it Lake Baikal. Am I right?"

"Yes, this is it. Lake Baikal is located in the Far East of Russia, in fact, it is the northeast region of our country during the Qing Dynasty, at that time we called it the North Sea, where the Su Wu shepherd sheep was in history, and it was also the hometown of the great poet Li Bai, but... Alas, forget it, don't talk about it, now it's Russian. ”

"Then why do you want to get water here?" asked Xiao Ai.

"Hmmm... First of all, Russia is vast and sparsely populated, and its natural resources cannot be described as abundant, it is simply rich to the point of being inhumane, and it is currently the only country in the world that does not lack any natural resources. Even the United States does not dare to say that it does not lack water. Speaking of this, Zheng Xudong got up from the pilot's chair of the plane and came to the one-square-meter space behind the chair that had just been upgraded to him, where he was going to change into a diving suit. While changing clothes, he said to Xiao Ai: "As for another reason, after I get water from Lake Baikal, it will not cause ecological disasters to the production and life of the locals, and I will definitely not do things that kill others by thirst for my own development." Wouldn't that be an ecological disaster to improve the environment here, but also an ecological disaster on the other side, which would deviate from my original intention!"

"Oh... It's so profound. I don't understand it for the time being, but I may understand it after I continue to upgrade in the future. ”

"Alas, I was also forced to do nothing, such a large area of land is too short of water. And it's not a small amount of water. Xiao Ai, do you know, I did the math, if I want to rain 10 centimeters on that 3,500 square kilometers of Nevada, do you know how much water you need?"

Xiao Ai immediately replied in his mind: "350 million cubic meters of water." ”

"Wow! You are calculating so fast!" Zheng Xudong sighed, "You are right, there is so much water at one time, and the land I bought is the kind of desert and Gobi that have been short of water for hundreds or thousands of years, and I dare not imagine that it will take 350 million cubic meters of water to make these lands full of water." This is only the land in Nevada, and after a while, there will be 3,500 square kilometers of Lop Nur, which adds up to 7,000 thousand square kilometers, and the 300 square kilometers in the UAE are simply negligible. A heavy rain in these places will take ... ”

"730 million cubic meters of water. Xiao Ai said immediately.

"Yes, that's the number, I remember, this water is not enough, Nevada still has those nuclear craters to be filled, I read the information from there, 53 nuclear craters, an average diameter of 80 meters, a depth of 50 meters, OH MY GOD! I HOPE THIS WORLD WILL NEVER FIGHT A NUCLEAR WAR! FILL THESE CRATERS NEED... ”

"The volume of water of 4.44 million cubic meters, which is calculated according to the fact that the pit is an inverted cone, may actually reach 5 million cubic meters. ”

"Xiao Ai, I found that with you, I don't have to use my brain anymore in the future. Zheng Xudong said with emotion.

"Master, no problem, leave these calculations to me. ”

"That is to say, a heavy rain of 10 centimeters will require 730 million cubic meters of water, Xiao Ai, do you know the flood control and storage capacity of the Three Gorges Dam?"

"22 billion cubic meters, found on the Internet. Xiao Ai said immediately.

"Okay, you cow!" accounts for 3.32 percent of the Three Gorges Dam's flood control capacity, which is just the amount of water that rains once. So you know how I am right now, I can't wait to put all the fresh water in the world. ”

"Master, actually, it's the first few times, um... Maybe a dozen times of rain will be harder, and when the grass seeds that have been improved by our gamma galaxy grow, it will change the soil conditions of the desert or Gobi there, and the soil there will naturally retain water in the future, and then a benign ecological cycle will be formed, and there will not be such a large amount of water shortage in the future. ”

"These are all theoretical things, and we have to wait until the grass seeds are actually planted in the ground. I hope your gamma galaxy's technology is reliable, otherwise I don't care about letting the world's media laugh at it in a few days, but Ivanka is estimated to kill me, she is a strong woman who wants to save face! I don't dare to think that nothing will grow in these fields I bought when the time comes, how crazy she will be, will she chase and kill me with Remington all over the world!" Thinking of this, Zheng Xudong felt a cool breeze on his back.

Talking to Xiao Ai, his diving suit was changed, and Xiao Ai told him that they were already above Lake Baikal now.

Zheng Xudong used manual operation to hover the plane five kilometers above Lake Baikal, the entire Baikal Lake is slender, before coming Zheng Xudong did detailed homework, checked its information, it is 636 kilometers long, but the average width is only 48 kilometers, it is the largest freshwater lake in Eurasia, with a water storage of 23.6 trillion cubic meters, which is also the reason why Zheng Xudong wants to come here to cancel, the amount of water is unimaginable. It is also the deepest freshwater lake in the world, reaching more than 1,600 meters at its deepest point. The whole of Lake Baikal is shaped like a hungry sea cucumber, slender and slender.

In the past, when Zheng Xudong was in school, his parents let him watch the TV program in addition to the CCTV news at seven o'clock, which was the weather forecast, Zheng Xudong's deepest impression of the sentence was "Affected by the cold air of Lake Baikal, most of China's northeast, north China, east China and other regions will be greatly cooled... Now I finally see the true face of this "culprit".

As the height slowly decreased, the entire Baikal Lake became more and more clear in front of Zheng Xudong's eyes, and the entire lake surface was like a black translucent crystal, flat without a trace of edges and corners, and like a long black scarf around the vast earth. It's just beautiful!

"Xiao Ai, I took a look, I am now above the very center of the entire Baikal Lake, can I go down here?"

"No, I can't. ”

“WHAT！”
