Lin Yuan's well-designed plan, in fact, as long as the Japanese army makes a move, it can be cracked, that is, the whole line retreats to Anton, Lin Yuan is very worried about this, he and Dashanyan have met once, from the conversation, it can be seen that Dashanyan's arrogance, such a person will not admit defeat easily, especially Dashanyan feels that he has never won Lin Yuan, and the battle for Anton's passage is his most decisive chance to defeat Lin Yuan.

Lin Yuan opened the telegram with trepidation, and the contents of the telegram made him ecstatic, which read: "The Qing army is attacking Benxi Lake and Mountain, and send reinforcements quickly!" "It's Dashan Rock.

Lin Yuan immediately ordered Deng Hong to blow up the bridge over the Yalu River.

In this season, the Yalu River near Andong has all melted, and the river water that has been suppressed for a winter is flowing wantonly, and the name of the Yalu River is related to its turbulent water potential, and the word "Yalu" is the transliteration of "turbulent flowing water" in the minority language.

On the river surface more than 100 meters wide, there is a stone bridge with seven piers, and the bridge deck is more than 10 meters wide, which is enough for a large number of Japanese troops to cross the river.

If you want to paralyze the bridge, the most convenient way is to blow up the bridge deck, but to do so you have to go to the bridge, and the amount of explosives carried is not less, the Japanese army has built bridgeheads on both sides of the bridge, and the people passing by are closely searched, in this case, it is impossible for the marines led by Deng Hong to carry a large amount of explosives to the bridge.

Capturing the bridgehead is not a wise choice, because their number is too small to be able to fight it, and after discussion, everyone decided to blow up the bridge piers!

Fortunately, the bridge piers are not very thick, Deng Hong The amount of explosives they carried is completely sufficient, and it is an underwater explosion, the explosion is more powerful, and the river is turbulent, so Deng Hong and they chose to dive upstream and use the current to drift to the position of the bridge.

Deng Hong they went around to the position of about a kilometer upstream of the bridge, here is the vacuum position of the Japanese patrol, by the dense night, Deng Hong began to go into the water to blow up the bridge, because the temperature of the water is very low, so Deng Hong first put on a thick cotton shirt and cotton pants, and then put on a diving suit outside, his diving suit is waterproof, the water can not soak the clothes inside, it is very suitable for diving in cold areas, he carried an oxygen cylinder, the oxygen in the bottle is enough for him to use for three hours.

The flow rate of the river reached an astonishing five meters per second, you must know that people swim in still water, the fastest speed is only 2.5 meters per second, Deng Hong holds a long hook in his hand, this long hook can ensure that he hooks it when passing through the bridge pier, and then he places explosives on the bridge pier, otherwise, the turbulent river will directly wash him downstream.

Deng Hongzhi said that he only had one chance to hook the bridge pier, if he couldn't hook, he would be taken to the downstream of the bridge by the water, and his swimming speed was not as fast as the flow of water, so he could not swim upstream in the water anyway, because the distance he swam up was not as long as the distance pushed down by the water, and the only way was to swim to the shore first, and then return upstream.

Getting closer and closer to the bridge pier, Deng Hong stretched out the hook, and at the moment when he crossed the bridge pier sideways, he suddenly felt a tightness on his waist, the hook hooked the bridge pier, and the rope on the hook was tied to his waist and dragged him.

Deng Hong pulled the rope, stood at the bottom of the water, against the huge current, and walked towards the bridge pier with difficulty, he took out the explosive block from the bag, and clutched it tightly, as long as the strength in his hand was slightly weak, the explosive block would be washed away by the water. The blocks of dynamite were filled with a special adhesive that could be used underwater, and he stuck twenty-five pieces of explosives to the piers, and the sweat had already soaked the cotton clothes, so he set up the detonator, hooked the bottom of the water with his hook, and trudged towards the shore.

Finally reached the shore and went ashore, and after almost an hour, he did not go to meet the Marines, because he saw that there were already Japanese troops walking on the bridge, and he hurriedly informed his comrades and detonated the explosives.

Seventy percent Octotojin and thirty percent Black Sokin, such a hybrid explosive is infinitely powerful! A muffled sound came from under the water, and a large number of bubbles rushed to the surface of the water, as if a pot was boiling, and the Japanese soldiers on the bridge were shocked, and they all looked at the bottom of the water curiously.

The disaster happened at this time, the bridge pier slowly fell, and together with the bridge deck above, it smashed into the water with a "boom"!

The Japanese soldiers above were caught off guard and were thrown into the water, and after the cotton clothes entered the water, they were unusually heavy, like a swarm of iron, sinking to the bottom of the water and being swept away by the turbulent current. Deng Hong saw that the explosion was successful, so he returned to the team, they knew that the Japanese army would definitely build a pontoon bridge, and they had to judge the location of the Japanese bridge, Deng Hong thought about it and said: "The tools for erecting the pontoon bridge are very heavy, so they will definitely use livestock to transport, so in this case, they must take the road, the road is connected to the bridge, so they will definitely build a pontoon bridge nearby." ”

The detachment quietly touched the side of the bridge, and sure enough, it was here that the Japanese army erected the pontoon bridge.

When the Japanese saw that the bridge was bombed, they immediately began to erect pontoon bridges, the so-called pontoon bridges, also called boat bridges, initially drove the boat to the water, fixed the boat with ropes, and did not wash away by the water, and then laid wooden planks on the boat, so that people could cross on it.

By the time the Japanese engineers arrived, it was already dawn, and they pulled the pontoon bridge with horse-drawn wagons, and their pontoon bridge was section by section, with pontoons underneath and planks on top, and when they were used, they put it into the water, fastened it to the object on the shore with ropes, and set it up.

To the surprise of the detachment, the place where the pontoon bridge was erected was piled up with Japanese troops, and it turned out that Deng Hong's plan was: to destroy the rope that fixed the pontoon bridge on the shore, but now that I look at it, this plan will not work at all, because the Japanese troops waiting to cross the river are piled up by the bridge, for them, the erection of the pontoon bridge is a novelty, they are all watching from the side, and it is basically impossible for the squad to get in.

At this time, one of the fighters said: "We still dive to the edge of the pontoon bridge like blowing up the bridge piers, the water is very fast, and there are many Lang flowers, and the people above cannot see the underwater situation at all." ”

Deng Hong said: "This method is very dangerous, I saw when I went into the water, the depth of the water is only ten meters, and the bullet is still lethal at thirty meters underwater, the water is very urgent, we can't stop in the water, if you want to stop on the edge of the pontoon, you have to hook the pontoon bridge with a hook, so it is easy to be discovered by the Japanese army, and it is inevitable that there will be casualties." ”

One of the team members said, "Why don't we do this, put the explosives upstream, let it go downstream, and when we get close to the pontoon, we'll detonate it." As soon as this method was proposed, some fighters said: "If you do this, it may not work, and if you drift upstream and downstream, it is very likely to hit the bridge pier or something else, and if the detonating device is damaged, it will not be able to detonate." ”

Everyone said a few more methods, but they all felt that it was inappropriate, time passed minute by minute, the Japanese pontoon bridge had been half erected, once the Japanese army crossed the river to reinforce Anton, Lin Yuan and Chen Fei's previous efforts were in vain, and the marines in the squad were anxious.

At this moment, Deng Hong looked at the rushing river, and an idea suddenly came to him, and he said to the soldiers of the team: "Look at this river, is the water level lower than yesterday?" ”
