Liu Hai knows very well what the task Hong Xuezhi gave himself is, that is, to arrange and deal with various problems between various stations and transportation nodes according to different situations. Guo Shan's situation in this place is not only bombing by the Americans, but also man-made disasters. This person may be said to be small because the instructor's ideological and political work is not in place, and if he is big, he is dissatisfied with the confrontation with the United States and aid Korea. After thinking about it, Liu Hai felt that it was still necessary to start from the ideological and political point of view, first solve people's problems and then solve practical difficulties, so Liu Hai reported to Hong Xuezhi, hoping to arrange an instructor with rich experience in political work to carry out political and ideological education first!

Soon the higher authorities sent a political cadre to serve as an instructor, and after arriving, he began to rectify the ideological education work! At the same time, Liu Hai also discovered the actual problem of this station, that is, this station is different from other places is that there are too few caves, and there are not many places that can be hidden. In response to such a question, Liu Hai thought that the fighter had spoken out about the practical difficulties, such a station should have enough anti-aircraft fire for cover, but the point was that there were only four anti-aircraft guns, and this number of anti-aircraft guns was too few for the station!

Liu Hai observed the surrounding terrain, this station is actually very topographical advantages, for example, there is a mountain to the east of the station, the soil is not very hard, it should be easy to dig a hole, as long as you dig a hole there, lay a section of rails, the train can directly lean on it to load goods or dodge bombing, it is really not possible to straighten the railway that has turned a corner here, pass through the side of the mountain, so that you can defend against air strikes to the greatest extent! In addition, anti-aircraft fire can be carried out with heavy machine guns on several nearby hills, and even if it can't be hit, the aircraft will be seriously threatened, in case it will definitely be profitable! After thinking about it, Liu Hai explained his thoughts!

"Oh, this is a good way, that mountain happened to be a coal yard in the past, there was a section of railroad tracks there, but it was abandoned after the war, and now it is just right to use it, dig the mountain next to it again, and match the original coal bunker, that is a station! Master Liu, your method is good! The station master said excitedly. If you think it's good, go and do it, go to the current station to bomb the Americans, move the materials in after the transformation there, and go directly to the road after loading, not to mention that the plane is not easy to find, that is, it is difficult for people to find within 500 meters, with this plan, isn't it easy for your work to carry out? Bangs said. Yes, yes, yes! The station master said.

The station manager did not dare to slack off, and immediately mobilized migrant workers to start the transformation of the foot of the mountain, and spent two days to change the original railroad tracks and coal bunkers there into ready-made stations, and then moved a large number of materials into the coal bunker, which was much larger than the previous warehouse, and could put more things, and the trains that came over drove directly from the outside of the railroad tracks to the outside of the coal bunker, and then loaded the trains, and put the wagons that had been blown up outside the station that had actually been abandoned to hide people's eyes and ears, and let the Americans blow up. Here is the loading of freight trucks in full swing, so that the Americans found out that Guoshan Station has been destroyed, but right under the noses of the Americans, it is in full swing to load supplies to the south!

"Let's go, things are done here, with these four anti-aircraft guns and machine guns on the hill are enough for the Americans to play!" Bangs said. "Then where are we going next, you can really do it, let the Americans throw dozens of pieces in vain every day, and the materials will not be delayed in the south, if the Americans know that you are transporting the materials to the south under the nose of the enemy's plane, they will not be angry!" "The Americans will not be angry, we have to consume 550 tons of supplies on the front line a day, and we can only supply half of them at present, that is to say, the soldiers at the front can only eat half full, what about the American soldiers, every day they eat canned beef, drink hot coffee, and ammunition is not comparable to us, it is not possible to go on like this, we must think of a way! You can't come to any more weeks of offensive, let people pinch your pulse, how can you fight! Bangs said.

"Division Commander Liu, the next stop is Bochuan, where the Bochuan Bridge is also the focus of the bombing by the Americans, I heard that the engineer company there has been killed and wounded several times!" The staff officer who followed the bangs said. "How can the engineer company suffer several casualties?" Liu Hai said with some shock, although Liu Hai is not very familiar with the engineer business, but the sapper is not a front battle after all, and the casualties are inevitable, but it is not so big! "Commander, don't worry, you'll know when you get there!" The staff officer said. Although he didn't catch up with the bombing of the Americans along the way, Liu Hai understood what was going on when he was still five miles away from Bochuan, there was not even a dirt bun around the Bochuan Bridge, and such a big bridge was repaired on this terrain, not to mention waiting for it, there was not even a place to shade the sun! The casualties are not serious, but there are ghosts!

"Hello Master Liu!" The commander of the engineer company of the Bochuan Bridge came to salute! "Company commander, I'm afraid you're not good!" Bangs said as he looked at the bandage on the company commander's head. "It's okay with this little injury! We are here, even digging a trench is under the wings of the enemy's plane, there is no way to settle this condition! The company commander said. Liu Hai looked at the Bochuan Bridge as he walked, this bridge was erected on the river, and the surrounding area was flat, and the bridge had been blown up. At this time, another reconnaissance plane flew over to reconnoitre, looked at the blown up bridge, shook its wings and flew away! "The supplies on the side of Guoshan are about to arrive, but the bridge is still collapsing, and the American plane comes to bomb every hour, and I have already killed more than a dozen soldiers!" The company commander said. "You bring the river map of this river, your brain is in the dirt when this bridge is repaired!" Bangs said. "Commander, there was no war when this bridge was built, who knew that there would be this time!" The company commander said and asked someone to bring the river map!

"You see, there is only one reason why this bridge is built here, and that is that the underwater terrain here is flat, which is suitable for ramming and building foundations, and I don't know much about construction, but can we take advantage of this?" Bangs said. "Take advantage of it? How to use it? The company commander asked curiously. Since such a good foundation, we can build another bridge! Bangs said excitedly. Build another bridge? "The company commander doesn't understand!" Ever heard of underwater bridges? Bangs asked. Underwater bridges? The company commander thought for a while, "I've heard that there are some hidden bridges built underwater, but although the underwater terrain here is flat, it is ten meters deep!" "What is ten meters deep, we can fill it with slate and stone at night, and then lay it on top of it, and then connect it to the rails, and put the road spikes, and then it will be a bridge?" Bangs said. "It seems that there is a little possibility in saying this, I will go to the old experts of North Korea to find a way!" The company commander said.

"It's not impossible!" After watching it for a long time, the old expert of North Korea said excitedly: "Master Liu, are you from a water conservancy background?" "Hehe, old man, I am an artilleryman, and if I want to talk about dealing with bridges, I have only learned a few days of military pontoons, and compared to you, it is a white hat!" Bangs said. "You're polite, you're really polite, I can't think of a way to solve it, but your solution has given me a wake-up call!" The old North Korean expert said: "We will find a way to build an underwater bridge, use the underwater bridge to run cars, and then use the broken bridge above the water to cover people's eyes and ears, so that the casualties of the engineer company can be greatly reduced, even if the Americans want to bomb it, he will not be able to see it!" Hahaha! "That's what I mean, old man!" Bangs said. "Okay, okay, I'll start planning right away!" The old gentleman said.

In the next few days, the old Korean gentleman immediately began to draw and study, after a few days of planning and research, the old gentleman made a plan and then took the engineer company to pour a large number of stones into the river at night, although the river surface is wide but the river is not urgent, the stones and stones poured into it quickly formed a stone dam under the water, and then the stone slab was paved on the top of the stone dam, and then the engineer company used sleepers to pad it, and finally paved the railroad tracks, and put on the road spikes, An underwater railway bridge became an underwater railway bridge after three days and four nights of hard work!

"Okay, if it doesn't work, you have to try! Fortunately, it is not a heavy car, although this roadbed is not very stable, but it should not be a problem to take such a car, tell the above to start it! The old gentleman from North Korea said. Sir, it depends on your professionalism! Bangs said. Speaking of which you are not allowed to believe, in addition to filling down the stones, the help of those stone slabs is the key, look, this time there are more materials, must pass as soon as possible, as long as today's car can pass, it means that it can work, and after the past, I am trying to find a way to strengthen the foundation pad, within half a month I guarantee that this underwater bridge can pass safely and unmistakably heavy vehicles, and then this Bochuan Bridge will become a decoration! The old gentleman said with a flushed face of delight.

Soon the train from Guo Shan arrived at the Bochuan Bridge, the whistling train rushed directly into the water, under the splash of water, the train rushed over one by one, the end of the train rushed over, the bangs standing by the river and the old experts of North Korea nervously looked at the movement in the water, for fear that there would be any movement, but when dozens of trains passed, there were only a few blisters in the water, and the overall situation was still very stable.
