Dom is undoubtedly a model for all workers, not only is he hard-working and unemotional, but he is also extremely efficient. After the two Doms fell to the ground, they turned around at the same time, and a white light shot out, submerging into the pile of things in front of them, and in just a few breaths, the two piles of mud-like piles were automatically sorted and stacked.

The black ones are a bunch of black, the white ones are a bunch of white, and the yellow ones are more embarrassing, because the amount is small, and it is estimated that you can only use a lump as a measure word.

"That's the harvest of a day?" Looking at the piles lined up in front of him, Wang Hao gasped in shock, and stacked all these things in front of him together, the volume was about the same as two adult cows standing side by side, if this was just the result of the work of two Taimu, then this efficiency would be too amazing.

"Yes, Mr. Wang Hao." Mary replied affirmatively, and then began to introduce, what color is what metal ore and the like, Wang Hao listened, and most of the enthusiasm in his heart suddenly dissipated. It turns out that the value of these metals in front of me is not very high. If you sell it, you may be able to sell it for thousands of yuan, which is a high income for ordinary people, but Wang Hao definitely didn't dare to think so. It takes a lot of energy to open the plane gate once, and if you run back and forth once a day, you have to open it twice, that is, the cost of this robot is almost zero, otherwise negative growth is possible.

But...... If you recycle all these materials to the base, you can make up for the energy consumption, or you can add a little more, but what do you want to do with this? Wang Hao was a little frustrated, of course he could take this bit of gold to sell for money, but it didn't go through a series of processing, purification, or something, it contained too many impurities, whether it could be sold at a good price or not, and it was troublesome, Wang Hao was most afraid of trouble, so it was better to directly recycle it for energy.

Thinking about it, Wang Hao sent two Doms to collect those things, and let them take them directly to recycle, now Wang Hao has a third-level authority, which is still a level different from the intelligent mastermind Mary, and in some places Mary can enter and control it unscrupulously, and he can't do it yet, but it's still no problem to command Dom, the lowest-level coolie.

"I wonder if we can open a permanent passage between the two planes?" After Dom left, Wang Hao asked Mary this question. When he brought the iceberg back, he pondered like this, what is lacking here is fresh water, maybe there is no need to go so far to transport the iceberg, not to mention the danger, the cycle is still long, and there are hidden dangers.

Wang Hao's original plan was actually very simple, that is, to get some money to build a freshwater conversion device, the sea is full of water, let's do it, just throw it over. There is a saying that it is easy to go from thrift to luxury, and it is difficult to go from luxury to simplicity. After eating the sweetness of fresh water for experience, Wang Hao really doesn't look down on the heavy work such as picking up debris and cleaning up the battlefield, and because of the abundant energy, more and more doms can be put into operation, and his labor force is even more dispensable.

But at the moment, it seems that things are not so simple, the loading capacity of Dom is established, and the time that the plane gate can maintain is also limited, if you want to open it once, send out more than n Dom, and then open it again to pull Dom back, this idea is very unrealistic.

Therefore, in Wang Hao's opinion, if a bridge can be built between the two planes, it is also a good way to do it once and for all. However, this is unlikely, Wang Hao already had a premonition when he said it, and when he got Mary's negative reply, he could only sigh helplessly.

"How much fresh water is available now?" Wang Hao asked Mary.

"About four-fifths of them."

"So fast!" Wang Hao had a creepy feeling, you don't need to think about how much water an iceberg melts, and it only took a few days to consume one-fifth.

"You take me to see where the water is used." Wang Hao hurriedly said that he felt that he might be able to make some articles here.

Following Mary, Wang Hao began his patrol work. The whole process lasted nearly four hours, but in fact, Wang Hao's emotions went from confusion, to surprise, to shock, to incredulity, to the final collapse, it only took more than ten minutes to complete this series of changes, and for more than three hours, he was in a state of numbness.

It took nearly a month to get an iceberg back, melt it down, and put it all into use, that's right...... But the problem is that all the used wastewater is thrown into a waste water tank, and then it is never bothered again......

"That's love!!" When Wang Hao saw the wastewater pond with an area comparable to Liuhu Lake, this sentence appeared in his head inexplicably, and then burst into tears. Because it wasn't until this moment that I realized that I had been deceived by superficial phenomena, and it turned out that Mary's IQ was obviously not high!

Wastewater...... Waste water just thrown away? With such a high technology, won't grandma drip purify it?

After listening to Mary's last report with a heavy heart, Wang Hao exhaled slowly, turned his head to look at Mary, and his eyes were full of sympathy. At this moment, a question that had plagued him for many days was finally answered - why is there such a shortage of fresh water in a place with such high technology, which is really a natural water shortage? The answer is obviously no, because: these pit dads don't think about recycling, but blindly want to ask for it...... No matter how big the mountain is, it can't be trusted! The dry ground inside and outside the base is the best proof of this!

After taking a few deep breaths, Wang Hao told her the truth of recycling, but Mary's face was full of confusion.

Wang Hao was a little stunned, thought about it slightly, and couldn't help laughing. No matter how advanced the technology is, no matter how intelligent the program is, it can't escape the fact that it is a program, and it will only play cards according to the established routine, obviously the guy who designed Mary did not teach Mary programs such as loops, so that she couldn't understand what Wang Hao said, in layman's terms, it was the wrong instruction, which led to an extreme lack of knowledge of how to run.

Holding the idea of a dead horse being a live horse doctor, Wang Hao patiently spoke a few times, and the miracle was born at this moment, and Mary, who was originally at a loss, suddenly seemed to be opened up to the second pulse of Ren Du, and instantly understood Wang Hao's words, and also drew inferences from a few examples. Wang Hao was dumbfounded, and finally found something that made him a little frightened, the intelligent program in front of him...... He even has a strong learning ability......

Shocked at the same time, Wang Hao couldn't help but be overjoyed, and hurriedly began to explain the truth of wastewater reuse. After doing this, he opened the plane door and returned to the room, and after seeing that the time was relatively late, he dismissed his plan to go down to exercise, and fell asleep after washing casually.

But what Wang Hao didn't know was that when he was lying comfortably in the bed, someone was heartbroken for him.

",! This guy shouldn't have evaporated from the world, why hasn't he appeared yet! "In a dark corner of the downstairs of an older teacher's dormitory, four or five sneaky figures huddled in a gloomy location, and from time to time a few deliberately suppressed complaints could be heard.

This group of people is Guo Bincheng's people, who fell into the pond instead of catching Wang Hao out of anger in the evening, which made the hearts of a group of people very angry, although I am not sure if it is Wang Hao's ghost, but such a tragic end is inseparable from him, so I decided to find this guts physical education teacher's bad head to relieve hatred.

But even if it is Guo Bincheng, he doesn't dare to make trouble openly in the school, even if he wants to make trouble, he has to make a low-key noise, such as finding a corner where no one is around. However, they don't have much in their hearts, and if the physical education teacher goes back to the dormitory after work and doesn't come out, then they also have no way.

Good news fell from the sky.

At this time, someone inquired about this timid physical education teacher who ran away when he encountered something, and he actually had the habit of going to the playground every night to give himself special training. Guo Bincheng and the others were very happy, so the soldiers divided into two roads, a group of people stared at the playground, and the rest of the people stayed on the road to this dormitory, waiting for the moment when the road was narrow.

As a result, half an hour passed, and an hour passed...... Four hours have passed, and what a sports-loving physical education teacher, there is not even a birdman on the playground! Waiting for everyone is like a big aunt, anxious mess.

"Is it still coming...... Ahh Ahh As he spoke, he suddenly sneezed several times in quick succession. At this time, it is already late autumn, the sun has already set, the evening wind is gusting, and the temperature difference between it and the day is really not ordinary, and several people are already trembling with their arms crossed.

"Wait another half an hour, if you don't come, we'll leave!" One person said hatefully that it was the leading brother Guo Bincheng.

The few people next to him didn't answer, they all looked at him numbly, they had heard this sentence two hours ago, and the fact was that they blew cold air for another two hours.

Guo Bincheng found that there was something wrong with the atmosphere, and immediately stopped talking, so after a while, those who should complain continued to complain, and those who should tremble continued to tremble.

Suddenly, there was a creaking sound in the sky, and everyone looked up almost reflexively, and the next moment, they only saw that their eyes lit up for a while, and then there was a warmth on their faces, and they touched their faces in a daze, and then touched their clothes, and then shouted loudly, ", water!"

When I raised my eyes, I saw an arm stretched out from a window above, and a basin was still firmly grasped in my hand, and I vaguely seemed to hear a woman's roar from upstairs: "You are useless, wash your feet and run to the toilet, don't you have a stool for you to sit on at home?" What about the footwash? Don't pour the toilet, it's blocked ......."

The group only felt a chill suddenly emerge from the soles of their feet, and when they looked at their companions around them, their eyes were full of disgusting taste, and they all subconsciously retreated, as if they didn't have foot washing water on their bodies.

"! Bastard! Is there a sense of public morality? Pour down the footwash water at night...... Woo woo woo woo ......" one scolded angrily, and before he finished speaking, he was held down by his companion, and then a group of people took advantage of the night to run away from school like crazy.
