Lin Yuan nodded and said, "That's right, your analysis is very reasonable, but this trick is not difficult to deal with, we just need to go up and check in advance to make sure there are no bombs." ”

Chen Fei shook his head and said: "This is difficult, the north side of the big stone bridge is less than five kilometers away from Aihui City, so there are defensive positions in the north and south of the big stone bridge, and it is almost impossible for us to go up to the big stone bridge to check." ”

Lin Yuan said: "Then it is really possible for the Russians to do tricks on the bridge, we must come up with a way to reconnoiter on the bridge." ”

As soon as the words fell, the two fell into deep thought, the big stone bridge is surrounded by the Russian army, is there any way to blend into the encirclement of the Russian army, go in to check if there are any bombs?

Just when there was no way out, Ilya suddenly sent a liaison officer to come and said: "In order to show our sincerity, we have taken the initiative to withdraw the defense on the south side of the big stone bridge, starting from the midpoint of the big stone bridge, and all the places south of it are divided into the defense zone of the Chinese side. ”

Lin Yuan and Chen Fei were surprised when they heard this, and they were thinking about how to go to the bridge to check, but the Russians sent the opportunity to the door, Lin Yuan smiled and said: "It seems that the Russians are afraid that I won't dare to go up to the big stone bridge!" This gave me a chance to check, and it seems that there is indeed a problem on the bridge. ”

Chen Fei and Lin Yuan then led people to the big stone bridge, the Russian army on the south side had retreated back to the north of the bridge, the reason why they dared to give up the south side of the bridge was because the river water at this time had formed a thick ice, so that the attacker could choose a point on the bank of several kilometers to launch an attack, so the river no longer had the slightest defensive value.

Lin Yuan and Chen Fei came to the bridge, and Chen Fei said, "Where do you think the Russians will lay bombs?" ”

Lin Yuan thought for a while and said: "According to the general structure of the bridge, the Russians will either plant bombs on the bridge deck or on the bridge piers, if they plant bombs on the bridge piers, they will blow up the bridge and then fall to my death, but this bridge is only less than three meters high from the ice, such a height, even if the bridge collapses, it is not enough to completely kill me." ”

Lin Yuan continued: "So I think they will lay bombs on the bridge deck, so that they can directly kill me, as long as the amount of explosives is enough, I have absolutely no chance of survival!" ”

Chen Fei looked at the neat stone slabs on the bridge deck and said, "Will they put the bomb under the stone slabs?" ”

Lin Yuan nodded and said, "Other than that, there is no space on the bridge deck where bombs can be placed, it seems that there is only one possibility." ”

Chen Fei stepped on the stone slabs lightly and said, "But there are hundreds of stone slabs here, we can't open them one by one and search them." ”

Lin Yuan said: "If you want to know which stone slab has a bomb under it, just open all the stone slabs, this is not the method that people in our time should have!" We can use ultrasonic flaw detectors, and if they want to plant bombs in the slate, they have to dig a space in the slab, and this space will definitely not escape our instruments. ”

Lin Yuan continued: "This instrument is very small, and it only takes us a day to transport it, tonight, as soon as our things arrive, we will immediately start probing, and when the detection is over, we will use the night time to open the slate and dismantle the bomb." ”

Soon at night, the ultrasonic flaw detection equipment had been delivered, and then Lin Yuan began to probe by the bridge, Lin Yuan and Ilya agreed that neither side should use lighting equipment to spy on each other's positions at night, so the Russian army did not find Lin Yuan and their actions.

In the deep night, Lin Yuan operated a small ultrasonic flaw detector, the bridge deck is very wide, if you search on the bridge deck little by little, I don't know when the road will be searched, Lin Yuan thought to himself: "The Russians have no way to determine the time of the explosion in advance, so they can only use remote control detonation devices, then they will definitely install wires from their positions." ”

Lin Yuan thought of this, so he walked to the middle of the bridge, searched horizontally, and finally found a hole with a thickness of a few centimeters under the stone slab in the middle, Lin Yuan thought to himself: "This should be the location where the wire is installed." Lin Yuan walked along this line towards his own position, and finally found a relatively large hole near the bridgehead.

Lin Yuan thought to himself: "This hollow must be the place where the bomb is planted." Lin Yuan gently tapped the stone slab with his hand, and then said to a few soldiers, "Come, let's pry this stone slab open." ”

This stone bridge was built a long time ago, and the stone slabs on it were smashed into the bridge deck, so as long as they used force, they could pry it open, and the two fighters used the crowbar to carefully put the thin end under the stone slabs, and when the sled was not pryed, Chen Fei stretched out his hand to press the crowbar.

Lin Yuan asked, "What's wrong?" ”

Chen Fei said: "What if the fuse of this bomb is connected to the slate? As soon as you pry the slab open, the bomb will explode. ”

Lin Yuan said: "Probably not, the Russians would not have expected us to find the bomb, so they would not have adopted that design, and I also found wires, so it is certain that they used wires to remotely detonate them." ”

After Lin Yuan finished speaking, he nodded lightly at a few soldiers and said, "Pry the stone slab open." ”

Several warriors worked together, and gradually the slate was lifted up into a gap, and two soldiers on the side immediately held on to the slate, and the gap became bigger and bigger, and the bridge deck made of sand, stone and loess was exposed below, and there was a hole in the bridge deck, and a large bag was placed in it, and a metal wire on the edge of the wrap extended out.

Chen Fei stepped closer, sniffed the smell of the package with his nose, and said, "It seems that it is indeed explosives in it, a bitter and sour taste." After Chen Fei finished speaking, he stretched out his hand to remove the detonator, put it aside, and then said with a smile: "This time, the bomb of the ** son will not work." ”

After Chen Fei finished speaking, he saw that Lin Yuan didn't react at all, so he couldn't help but push him and asked, "What are you thinking?" ”

Lin Yuan said: "I think of an incident in history, in our time, in 1900, the Russian army took advantage of the opportunity of the Eight-Nation Alliance to attack Beijing, and once sent troops to occupy the entire Northeast, and when they attacked Qiqihar, they used such a trick. ”

"Before they attacked, they first pretended to negotiate peace with the Qing army, and signed an armistice agreement, the Qing army withdrew from the defensive positions outside Qiqihar, and the Russian army was not allowed to occupy it, but when the agreement came into effect, they actually betrayed their promises, opened artillery to bombard the retreating Qing army, and took advantage of the situation to occupy Qiqihar."

When Lin Yuan said this, he smiled mysteriously and said: "The Art of War often says that 'soldiers are not tired of cheating', ** can cheat, why can't we do it?" ”

Chen Fei said: "What do you mean: we take advantage of the exchange of prisoners of war to attack the Russian army? ”

Lin Yuan nodded and said: "That's right, that's exactly what I mean, we ambush the next group of people, and when the prisoners of war are exchanged, we will kill Baroyev and his entourage, and when the Russian army is leaderless, won't we be able to successfully capture Aihui City?" ”

Chen Fei looked around, there was a flat snow everywhere, and there was not even a place to hide, how could an ambush be set up in such a place?
