Liu Hai followed Chen Yong to the anti-aircraft gun position of the bridge, and after going up, he found a big problem, the location of the bridge is very strange, there are no mountains on both sides, only the front and back of the bridge have mountains. There is no problem with the anti-aircraft position, but because the firing range is too long, we have to wait for the US planes to drop bombs and pull up before we can reach the best firing distance! "This terrain is weird," Liu Hai said to himself. "You're right, Commander Liu, our anti-aircraft artillery is very hot, either it can't reach it, or it's too late to fight!" Chen Yong said.

Bangs looked back and forth, and found that although the bottom of the bridge is very high, it is only a few tens of meters after all, and it does not have much impact on the range of anti-aircraft guns. "Chen Yong, I think there are a few doors that can be placed under the bridge, although the vision is not very good, but for the enemy aircraft bombing at low altitude, the threat is still very great!" Bangs said. "I thought so too, but below is the work area, and besides, there are no extra anti-aircraft guns, so I didn't put it!" "Then now there are anti-aircraft guns, which can be placed!" Bangs said. "Okay, I'll arrange it right away!" Chen Yong said. In addition to the bottom of the bridge, Liu Hai looked to both sides, and after careful observation, Liu Hai found that there were several holes in the side walls of the front and back of the bridge, and after asking, he learned that they were tunnels dug by North Koreans in the past. "Chen Yong, I think those holes can be enlarged a little bit and put two anti-aircraft guns, if that position is hit, it will be enough for the Americans!" Bangs said, pointing to the side wall. "The point is that enemy planes can't hit!" Chen Yong said: "Why didn't I find out earlier! I'll immediately call Company Commander Xu and them to open their eyes and fire the cannon! ”

Under the command of Company Commander Xu, the engineering troops carried out blasting at the openings of those holes, expanding the openings to the space where an anti-aircraft gun could be placed, and after several blasts, three anti-aircraft guns were placed on the side wall. In the course of the attack, the US military planes also felt the law, the geographical situation and attack methods of each bridge were accumulated in the process of long-term air raids, for this bridge, the US pilots also knew in their hearts, several US planes began to attack in accordance with the previous attack methods, although the bridge was not rushed through at this time, but the US military planes still decided to throw a few*!

As usual, the US military plane that rushed down and dropped the bomb had just taken root, and a string of sparks floated out of the cliff on the side, and this string of sparks quickly hit a US military plane. Before the US plane could react, a series of shells came up below, and the anti-aircraft guns arranged by Liu Hai under the bridge opened fire, and dozens of shells exploded a volley of US planes, and the frightened US pilots hurriedly pulled up the plane, but the anti-aircraft guns on both sides of the bridge also fired, and a few shells passed by, although the plane was not shot down, the radiator was broken, and a puff of black smoke came out, and they hurriedly pulled up and flew away! This time the air ambush was a success!

"Good, good!" Chen Yong ran over with a spring breeze on his face, "Great, Master Liu, you played too well!" Hahaha! "Leave a few cannons for you, and guard this bridge!" Liu Hai patted Chen Yong's shoulder and said. "Don't worry, Senior Liu!" Chen Yong said. "By the way, I will put dozens of boxes of shells for you, and after the bridge is cleared, we will continue to go south!" Bangs said. "Okay! I'll tell them to start grabbing right away! "Chen Yong ran out! Shooting down two enemy planes at once, the morale of the entire bridge was high, and the railway soldiers and sappers, under the infection of this emotion, spent two hours less than usual on the bridge, while rushing through the bridge! Bangs continues south on the train!

"What's next?" Bangs asked. "The next stop is Yumin Bridge, this bridge is the most difficult bridge to defend north of the real triangle area, and it is also the most vulnerable bridge, where there is a yard of Pingchuan, but there is a river, that bridge is usually desperately rushed through, and it is also the easiest bridge to pinch the neck of the northern line!" The conductor on the train told Bangs! "Let's go check it out," Bangs said. After the train stopped at the station of Yumin Bridge, sure enough, Yumin Bridge was broken! Liu Hai found the anti-aircraft artillery commander here, but the result was carried over, just half an hour before Liu Hai arrived, a group of US planes came to bomb, the anti-aircraft artillery commander was seriously injured, and seven anti-aircraft guns were lost! Liu Hai took a look at the terrain here, but there is actually no terrain, because it is a flat river, and then there is a lonely bridge in the middle!

"What the fuck!" Liu Hai couldn't help but scold, there was no cover at all before and after, the plane passed from the sky, and the entire bridge area was unobstructed, no matter how you arranged it! The most hellish thing is that there is no large vegetation on both sides of this broken river, and there is not even a foundation to hide camouflage, how did this place hold on for so long! Just looking at it, several US planes were once again volleyed, the anti-aircraft guns on the ground were fired again, and a string of anti-aircraft artillery shells hit it, and after a few tumbling actions in the rain of bullets, the US planes easily dropped *, and then pulled up and flew away! "Division Commander Liu, you should think of a way, we are the work area with the largest casualties on the entire northern front, the emergency repair troops have been changed twice, and the losses of anti-aircraft artillery are also extremely heavy! I'm limited, and this is wasted, but this bridge can't be wasted! The anti-aircraft artillery commander lay there and said bitterly. Rest assured to heal your injuries.,At first glance, it doesn't seem like there's any curse.。。。 Liu Hai walked to the entrance of the cave and looked at the Yumin Bridge and began to think!

"That's it!" Liu Hai called the instructor of the anti-aircraft artillery command. "Did you just find out, when the US planes are bombing, they always like to attack from both ends of the bridge, so that they can fly over the entire bridge deck to increase their bomb surface, when they fly over the bridge that is the end of the bomb drop, they will turn around, and then come again, at this time their planes are either pulled up to the left or to the right, as long as our anti-aircraft artillery is arranged in a goose shape, and a linear strike is carried out on their pulling route, he has no way to run away!" Bangs said. "Hey, it seems like that's really the case!" The instructor comrade said: "Commander Liu, I will arrange it immediately!" ”。 Under the arrangement of this instructor, the anti-aircraft guns of Yumin Bridge rearranged their formation, and sure enough, in the next anti-aircraft battle, they shot down three enemy planes in one fell swoop!

"What's going on, the battle damage has risen in a straight line these days, and if it goes on like this, all our fighters will fall!" The commander of the Air Force said as he looked at the loss table. "The enemy has strengthened its anti-aircraft firepower in recent days, especially in some key areas, and has adjusted the formation of anti-aircraft shooting, and our record has not adapted for a while, so we have lost some fighters!" The adjutant said. "The enemy is still replenishing, their front line is being fed every day, this is unacceptable, we must find a way!" The commander of the Air Force said, "Concentrate the heavy bombers, carpet bomb them from a high altitude, eliminate the anti-aircraft positions around them, and then attack!" "Yes!" The adjutant agreed.

"This bridge is famous!" Liu Hai looked at the Nameless River Bridge in front of him and said, "You, Company Commander Guo Tie, are even more famous, and within a month, you have robbed the Nameless River twenty-one times with tons of color*!" "Senior Commander Liu, you are polite, you are the command and support of the chief!" Guo Tie said. "Where are your anti-aircraft artillery positions here?" Bangs asked. "Our anti-aircraft artillery here is a squadron, it is the unit of the North Korean comrades, the squadron leader is called Choe Zhishan, his squadron is divided into three squadrons, arranged on the three commanding heights here, and the anti-aircraft shooting is very set, which greatly supports our work!" Guo Tie said. "The anti-aircraft positions here are well arranged, and there are firepower arrangements for low, medium and high!" Liu Hai took a look at the topography and anti-aircraft artillery positions here, and felt that this Cui Zhishan had arranged it well!

"Report, the Sky Bird Cave forty miles away was bombed, the anti-aircraft artillery and roadbed were seriously damaged, and the enemy's bombing methods were different, all of them were horizontal area bombardment by large bombers!" A correspondent came running to report! "Area bombing?" Liu Hai looked at the Nameless River Bridge and said, "The terrain here is definitely not suitable for area bombing, but the flat terrain of the Sky Bird Cave really can't be prevented!" "Then we... Guo Tie said. "What are you supposed to do, when the bombing comes, just stay put! Area bombing doesn't play a big role in the terrain here! "Then we'll rush through tonight, and your train should go down quickly!" Guo Tie said. "Okay!" Liu Hai said, "By the way, inform the comrades of Yumin Bridge that all the anti-aircraft guns are waiting to be destroyed, and they will come out after the bombing!" ”

That night, Guo Tie took his Ninth Company to successfully repair the bridge after half an all-nighter, and Liu Hai's train passed through the Nameless River Bridge and continued to go south for his own guidance, and at this time he suddenly received an order, Liu Hai quickly returned to the logistics headquarters, ready to accept a new mission! Liu Hai thought about it, ordered the southbound train to continue south, dispersed and replenished the remaining anti-aircraft guns along the various lines, and returned to the headquarters himself! After Liu Hai returned to the headquarters in a hurry, he found that there were many doctors and nurses in white coats in the headquarters, who were disinfecting and spraying disinfectant everywhere!

"Minister Hong, what does this mean?" Bangs asked. "The Americans of the dog day can't beat us, and now it's a trick! Their planes are spreading some infected critters and canned food everywhere, which is to say that they are fighting germ warfare with us! There are people infected in the entire three eastern provinces, the Yalu River and the northern line, and calling you back is to ask you to return to China to escort a batch of medicines and medical personnel to North Korea, and now these viruses are spreading very quickly, without further ado, you leave immediately! ”
