A treasure-appraisal maniac

.

Lu Fei's group of brothers are best at entertaining themselves. They didn't have much to laugh at originally, but when these guys got mixed up, the whole audience burst into laughter. Of course, forced demolition is not enough. High-tech equipment is now everywhere in every corner. Isn't it just cleaning up the silt? Employees said that this job is very simple. A high-pressure self-priming sand pump goes down from the ship and uses a machine.

It can be done by people controlling it from outside, and it can be done with the perspective of a small submarine, perfect!

Lu Fei had to sigh, the power of science is so powerful.

Just do it. The self-priming pump quickly went down to the bottom of the sea. It was controlled by the robot and tested on the sediment on the bottom of the sea. The effect was very good and the suction power was very powerful.

Lu Fei couldn't help but ask after seeing it: "With such a practical machine, why didn't it be used when cleaning the seabed sediment before?" The employee replied: "Although the sediment self-priming pump has strong suction power, the coverage area is too small, and it is only suitable for incoming sediments." Fifty centimeters around the mouth of the sand are effective, but beyond this range there is no effect. The area around the sunken ship is too large.

A self-priming pump has to work continuously for at least two or three days, and its efficiency is not as fast as that of a robot. "

Lu Fei understood and nodded.

The experiment was successful. The robot immediately controlled the self-priming pump and entered the cabin. Following the guidance of the small submarine's line of sight, it came to the sand pile and started the self-priming pump. The employee turned on the low gear first, and the effect was also obvious.

The advantage of using low gear is that it will not stir up large areas of turbidity. If there is good stuff under the sediment layer, it will not cause too serious damage. However, Lu Fei looked at it for a while and expressed that he was not satisfied with the current efficiency.

"Add another gear."

"boss....."

"It doesn't matter, the sediment layer should be very thick, and it won't be cleaned up in a while." The employee added another level, and the quick freezing was obviously much faster than before, but the shortcomings were also reflected. Although the self-priming pump had strong suction, it still The mud and sand were stirred up, and the cabin became more and more turbid. After a while, it was completely invisible.

After clearing the water, Lu Fei had no choice but to stop the machine. After a few minutes, the sediment settled and the sea water became clear again.

"Damn it, it's really a wooden bar!"

"Brother Fei's eyes are still poisonous, Big Leizi, Nite's eyes are just for blowing your nose."

"Hahaha!!" There was another burst of laughter, and Lu Fei also laughed, because he saw it right, some of the sediment was cleared away, and the exposed "little corners" became more obvious. Before, it was only about ten centimeters, but now A little over thirty centimeters can be seen. This time, Lu Fei didn't need to explain. Everyone could see that it was indeed a broken piece of wood. Moreover, it might be because the piece of wood was buried in the sand and rotted. A little slower, but still with some toughness, even so

The powerful sediment self-priming pump failed to cause secondary damage to it.

At the same time, everyone is looking forward to it even more. This wooden strip does look like a part of a wooden box. If there is a complete wooden box underneath, maybe you can really find something good. With the previous effect, Lu Fei didn't want to be too hasty, so he started the first gear of work. Although it was a little slower, the effect was also very good. The most important thing was that it would not stir up mud and sand, and he could see clearly. With purpose

The cleaning effect can only be better. Next, based on that piece of wood, I started to clean it up bit by bit. After ten minutes, I made a major discovery. All the pieces of wood were cleared out. It was exactly as Lu Fei had guessed. The edged piece was Wood

The packaging boards of the wooden box were broken and stood upright, and they were well preserved. Even if they were all cleaned out, they were not broken and were still strong.

"Hey, Brother Fei is amazing, your guess is not bad at all!"

"Bullshit, do you think Brother Fei is just like you, talking nonsense all day without any purpose?"

"Damn, your blatant flattery is so disgusting, isn't it?"

"Haha, you are going too far. This is not a guess. Brother Fei has already seen it. In this regard, our eyesight is incomparable to Brother Fei's."

"That's right. Let's not talk about us. In the entire China, even foreigners, no one has better eyesight than Brother Fei. This is a recognized fact."

"Speaking of which, there is no need for you to belittle yourselves. Brother Fei is right. There are specialties in surgery. This is Brother Fei's profession. In this field, it is normal for us to be inferior to Brother Fei!"

"Damn, what you said sounds like there's nothing wrong with you. In fact, it's just to put your own face on. My brother not only has great eyesight. What do you think you can compare to my brother?" Agree said.

Everyone was very unconvinced.

"How not?"

"That's what you said?"

"I can eat better than Brother Fei."

"I can sleep better than Brother Fei!"

"Damn, you're better than Fei Ge!"

"Hahaha!"

"These don't count, are there any more?"

"Yes, I am better at picking up girls than Brother Fei, does this count as a serious skill?" "Well, it should be counted, but you are sure that you are better at picking up girls than my brother, who has two wives. , and it’s all legal. What’s even more awesome is that the two sisters-in-law don’t fight, they are as harmonious as sisters, you

Is it done? "When everyone thought about it, they couldn't help but gasp. It seemed that they really couldn't compare. Just when they were about to follow Di Ruilong's words and praise Lu Fei, suddenly, Di Ruilong's conversation came to mind, and then came the news. The sister-in-law roared: "Little Loach, do you want to die? "
