"Commissioner Li, good morning." The next day, at seven o'clock in the morning on March 6th, 1940, Li Yan woke up and found that Xu Chang and Hu Rui had already woken up. However, he didn't know what Xu Chang had gone to do. Only Hu Rui was left beside the bonfire, boiling water with an iron lunch box.
"Morning, where's Xu Chang?" Li Yan asked as he put on his coat.
"Brother Xu went to look for firewood. After all, the firewood has been burned out overnight.”In fact, Hu Rui was the first to get up in the morning. After getting up, he boiled the water. Then, Xu Chang went to find some firewood after washing up.
"Really? I'll wash up first." He was not surprised. At first, Li Yan thought that he was the first to wake up. However, it seemed that his biological clock had not changed. After all, he had become lazy in the past two months.
"Yes, there's hot water in the kettle." Hu Rui also started to prepare, putting the steamed buns by the fire to roast. Although it would become very dry, it was much better than eating cold ones.
After Li Yan finished washing up, Xu Chang also rushed back with firewood. Because they still had missions on them, they quickly finished their meal and continued on their way, continuing to walk in the opposite direction.
Fortunately, they didn't have to rush for too long to find a suitable location. After leaving Wuzhuang Village and Tazi Mountain, the three of them finally arrived at a suitable location.
"Commissioner Li, do you think it's okay in front?”Hu Rui, who had been walking in front, was the first to discover the river section.
"Let's go over and take a look. It should be about the same.”Li Yan also saw it. The suitable location was north of Tazishan Village and Lianyizhuang Village. It had to be said that the Meng River had a very sharp bend at the back of Tazishan Village. This was a big problem for the planned irrigation canal, so Li Yan remembered a lot in his notebook.
When the three of them could walk in, they finally saw the full view of the river. The suitable river was about 300 meters long and 60 meters wide. Perhaps due to the dry season, the surface of the water and the road were about one meter wide. The depth was still relatively large. At least, the bottom of the river could not be seen from the shore. Further ahead, he could see the shape of the water entrance that had obviously changed from small to large.
"How is it, Commissioner Li? Are you sure this is the place?”Standing by the river, Hu Rui asked Li Yan. From Li Yan's previous words, Hu Rui thought that the water surface only had a certain requirement for the width, so Hu Rui thought that it was enough here.
"Not necessarily. A 1000KW power station needs at least 100,000 cubic meters of water, and the average water depth needs to reach about 7 meters to meet the requirements.”
In order to know the exact amount of water stored in the river, he had to measure the depth of the water bit by bit. After all, along the way, he had observed that there was not only sand in the river, but there were also many places where stones were exposed. In order to be more certain, he had to go into the water. Now, Li Yan was a little glad that Xu Chang had majored in geography. After all, a graduate with a major in geography might not know anything else, but swimming was a necessary skill.
Looking at the area, if he and Xu Chang worked together, they would only need a day and a half to roughly get the water storage capacity and a simple topographic map. If Xu Chang had learned mechanics, he would have to do it himself. It might take two to three days to complete. As for Hu Rui, Li Yan, who looked like a soldier, did not think that he could master the professional ability to measure the depth of water.
"Of course. I'm a geologist after all. I'll go find more firewood first. The weather is still relatively cold now, so I'll find some calibers and warm up.”As he spoke, Xu Chang had already run to the river to collect firewood.
Li Yan took out his notebook, and while drawing a simple icon on the notebook, he explained to Hu Rui. "Little Hu, Xu Chang and I will go down to measure the water depth later. You probably don't know how to measure it, so you stay up there and count. Later, Xu Chang and I will call out the number to you. You have to listen well and write it down on the form. By the way, do you know the simple ABCDEF?”
"I know. Although I don't speak foreign languages, I can still write the 26 letters. I learned it in Yan 'an before.”
"It's good that you know. Look, the water surface is 60 meters wide, so I've written six letters here, ABCDEF, which is five meters each. We're now at the southwest corner of the water surface. This order is the distance from west to east. The length of the water surface was about 300 meters. It was a number of 10 meters. This was the distance from south to north, from 1 to 30. Xiao Hu, I'm asking you now, what does B15 mean?”
"B15, it is tens of meters from the west and 150 meters from the south. Am I right?" Hu Rui responded to Li Yan with a little uncertainty. In fact, he could actually be sure that this answer should be correct, but Hu Rui himself was never very sure. It was the same when he was studying in Yan 'an.
"Yes, tens of meters from the west and 150 meters from the south. It seems that you have mastered it very quickly. How about this? Look at it for a while more and remember it. When you hear it, write it down in your notebook and shout it at us again. I'll get two simple depth sounders.”
After Li Yan gave the notes to Hu Rui, he went to get a simple depth gauge. Although it was called a depth gauge, it was actually just a very long rope. One side was tied to a stone, and the other end was empty. Then, he made a simple distance ruler on the rope and completed it. Of course, in the United States, he could directly use the extension rod. He didn't have to go into the water, but he had no choice. The conditions were simple. Speaking of which, he bought the rope when he was in the city to sew clothes. As for the meter ruler... For engineers, simple measuring tools were always carried around.
After setting up two simple depth sounders, Xu Chang returned with a large bundle of firewood and a lot of rocks wrapped in his coat. After passing the depth gauge to Xu Chang, Li Yan also told him the unit of measurement. It was very simple to tell Xu Chang.
After all the preparations were done, Li Yan did not warm up because it was quite troublesome to make the depth sounder. He began to prepare to go into the water. Before going into the water, he used Xu Chang's coin to decide who would go east. In the end, Xu Chang was better and drew the west side.
Hu Rui was already stunned. He remembered that when he was in Yan 'an, someone said that Xu Chang took off his clothes and took a bath in the water, saying that Xu Chang was acting like a hooligan. But now it seemed that Xu Chang was testing the water depth.
Moreover, it was just the new year, not yet the first month. The ground had not completely melted, and it could be said that it was still freezing cold. The two of them had suffered a lot when they went into the water. Previously, he thought that the two of them were looking for a boat.
“A1681。”Xu Changfu came up and shouted at Hu Rui, but after a while, he still didn't hear Hu Rui's echo, so he had to shout again. "Xiao Hu, A1681."
Hu Rui also came back to his senses from his daze. He hurriedly found the position on the form and replied to Xu Chang.“A1681。”
“F1608。”“F1608。”
“EB796。”“B1796。”
…………
“C71152。”“C71152。”
“D71258。”“D71258。”
After all, the two of them went into the water very late. They only went into the water at nearly nine o'clock, so it was time for dinner after only measuring 70 meters. Because of the cold weather and the fact that they didn't eat much in the morning, they had only eaten a steamed bun. After a morning, they had long digested it, so the two of them caught up.
Hu Rui had already lit up the bonfire at 11 o'clock. The fire was burning brightly, and the steamed buns were baked in advance. When the two of them decided to come up, they immediately found their towels and clothes. When the two of them came up, they saw that there was no one around, so they didn't have any qualms about their image. They directly went naked. After a simple wipe, they put on their clothes and began to eat by the fire.
One of them was freezing because it was sunny and cold now, and the other was tired from swimming non-stop in the morning. Therefore, the two of them kept trembling after coming up, and it was the same when they were eating. Hu Rui kept wiping his eyes at the side.
One was Li Yan, and the other was Xu Chang. One of them had returned from studying at the University of Houston in the United States, and the other was the person with the highest academic qualifications in the base that Commander Zhao had mentioned. He was even more educated than Xu Chang. They could live a luxurious life in Beiping and other places without any danger to their lives, but now they were risking being killed by the Japanese in Shandong to go into the water to measure the depth of the water in winter. Li Yan saw Hu Rui's expression and comforted him instead.
"Little Hu, it's fine. The two of us were only a little tired for the past two days. We'll be fine after that.”
"Mm. Commissioner Li, you must teach me how to go deep in the future.”Hu Rui even wanted to replace the two of them in the afternoon, but Hu Rui also knew that sounding was not that simple. He knew how to swim and knew that it was difficult to know the distance under the water, not to mention how far it was. Even if it was north, south, east, and west, it was very difficult to know.
"Alright, we'll teach you when we're free.”Although he said that, Li Yan knew that it was not easy to learn underwater ranging. Moreover, when the industrial zone was established, simple measuring machines would have to be produced. By then, there would be no need to learn such things.
"By the way, Commissioner Li, can you come up earlier in the afternoon? We've finished our steamed buns and only some pickles are left. I'm going back to get food in the afternoon."
"It's okay. We'll come up at around five in the afternoon. You should go early and come back early. By the way, do you know which office I'm in?”Li Yan wanted Hu Rui to bring two bottles of wine over when he came back.
"I don't know about that, but I can ask Commander Zhao. He must know. Why?”
"How about this, if you meet Commander Zhao or Secretary Zhu in the afternoon, ask them. The office door is not locked. After you enter, you will see a large suitcase next to the desk. There are more than ten bottles of green wine in the suitcase.”
"Okay, I'll remember it. When I meet Commander Zhao, I'll ask him.”Although Hu Rui said so, he had already decided to go find Commander Zhao first after he went back. First, he wanted to report what he had seen these two days, and second, he wanted to ask Li Yan's office and bring the wine over.
"It's already 12:30. How about it, Xiao Xu? Can you hold on?”
"Of course. If you can't do it, I can." Although he said that, Hu Rui knew that Xu Chang was so tired that he ate one and a half steamed buns in the morning, but he couldn't eat the remaining half no matter what. When Li Yan was talking to him, Xu Chang was so tired that he did not even have the strength to raise his head. But Hu Rui had no choice. He could only listen even more seriously on the shore.
