The majority of the Japanese army was actually in Dongbetsu and defended against the north, which was a direction they did not dare to take lightly, because they had been brutally defeated.

The gap in casualties between the two sides was huge, and the confidence of the Japanese invaders was destroyed, and their most elite Kwantung Army was placed in the northeast, not daring to move a single inch.

……

A few days later, the Unconscionable Cannon was developed, which could hold 10-20 kg of explosives and fire at a distance of between 150 and 200 meters.

Then came the mass manufacturing, and the two experts worked tirelessly, and the new group could only mention the highest to the two in terms of food.

"You guys eat so well in your new ball, huh?" Expert Zhou sighed while eating.

"It's really hard work, there's only so much we can do!" Li Yunlong said with a smile on the side: "In addition, our new regiment has captured a lot of battles before, but now it is also eating the old book, and the little devil has shrunk a lot recently!" ”

"Like a turtle shell, we need this kind of run, two experts give it a name, right?"

"Hmm...... How about calling it a flying thunder cannon? Expert Zhao thought for a while and said.

"Okay, let's call it the Flying Thunder Cannon!" Li Yunlong slapped his thigh happily, "Although it is simple, it is easy to use, and it is easy to manufacture, and it is definitely a sharp weapon when attacking the city!" ”

The early appearance of the flying thunder cannon provided a sharp weapon for the Eighth Route Army, and it was absolutely easy to use when fighting the turret in the future!

He Jiaming also has some confidence in his heart, but it is also very dangerous, once this is not good for the ironclad train, then their reconnaissance company will be unlucky, so the earthwork work still cannot be saved, and the fortifications must be done.

And the fortifications also need to be hidden!

This needs to be deployed in advance, and He Jiaming and soon set off with twenty flying thunder cannons, as well as dozens of explosives and medicine packs!

Time is running out now, and at the same time, the new regiment has been training intensively, and its supplies are depleted quickly, and now they need to be replenished, and because of the orders of the division headquarters, they cannot go to other areas.

Rushing during the day, they arrived near the railway before dark, and then waited for it to get dark, and the reconnaissance company found a place about 15 meters away from the railway and began to dig.

Instead of hitting on one side, ten thunder cannons were deployed on each side of each side, which was a deployment against ironclad trains.

The explosion finally covered the ironclad train in all directions, knocking the enemies inside to death, which was the only way.

To say that explosives were planted under the ironclad train?

How much do you need?

The Eighth Route Army did not have high explosives, and there were so many of them that they were piled up on the railway?

The foundation of the railway is not easy to dig, of course, He Jiaming can use a sharp shovel, but they don't know the weight of the ironclad train, how much can be overturned?

These are all problems, so the Flying Thunder Cannon can be said to be the best option for the time being.

Soon the running position of the Flying Thunder Cannon was prepared, loaded with firing packs and explosives packs, followed by the fighters' bunkers and camouflage.

"The position of the grenadier squad is here, don't fire without my order, once you receive the order, shoot three rapid shots directly, and then immediately retreat!" Ho Ka Ming began to deploy other combat units.

There won't be too many people left in front, just after launching the explosives package, waiting for the enemy's movement, if the enemy still has combat effectiveness, then He Jiaming must consider how to lead people to retreat.

This requires cover fire, suppression from all sides, and a retreat must also be made after a round of full cover with grenadiers and light machine guns.

Or to disturb the enemy's line of sight and force the enemy to retreat, after all, after so many explosive packets explode, even if the little devil is not dead, then he will not be alive.

There must still be injuries, they may not have any combat effectiveness!

In addition, He Jiaming planned to rush directly to the ironclad train after the explosion, even if the enemy still had combat effectiveness, but there was also a gap, which was also an opportunity.

But no one else can do it, only him, after all, he is a man with 20 points of physique, and has many melee skills, all of which are elite-level.

He can try his hand at using a sharp shovel to open enemy hatches, and then use his pistol and throwing knives to settle the battle.

The ironclad train is not a car, and it stops when you subconsciously press the brakes, so you have to rush over and board it.

……

After the deployment, the soldiers of the reconnaissance company began to rest, and after a simple meal and drink, they went straight to sleep.

He Jiaming wanted to act in the early morning, but mainly depending on the enemy's patrol time, and the enemy's patrol was not regular for the time being, especially during the day, during the peak period of passenger car operation.

There were two trains that night, but they were all passenger cars, and the ironclad trains they patrolled did not go out at all.

This is a good piece of information, is the enemy merely making sorties before the departure of the trains?

The wait continued, and after dawn everyone was hidden, and the wait was so difficult that it was not until the afternoon that the whistle could be heard in the distance.

He Jiaming didn't have a probe, and looked directly at it with the small map, and a separate ironclad train was coming.

This self-powered ironclad train is relatively long, and although the whole body is covered with armor, it is actually the length of one more carriage than the front of the locomotive.

Two guns were installed on it, already numerous firing holes, which made it possible to mount light and heavy machine guns for firing.

Of course, there are longer ones with more fierce firepower, but the Jin Province side does not, and the stronger ironclad train is also in the northeast, and it is the north that is guarded.

In the case of the lack of heavy weapons in the Eighth Route Army, the Japanese army did not need too strong firepower, and the Tongpu Railway was not a key transportation line of the Japanese army, and the Pinghan Railway was the main artery of the Japanese army now.

"Huh......" He Jiaming took out a small flag and waved it behind him, and on the ground hundreds of meters behind him, there were soldiers of the reconnaissance company, and after seeing the signal, they immediately gave the same signal.

Because the roadbed of the railway is very high, He Jiaming could not signal the people who were in ambush on the opposite side, and then sent a signal behind him, and then they made a transfer.

Liao Gensheng was in charge on the other side, and after seeing the signal, he immediately notified everyone to prepare.

He Jiaming began to use the small map to calculate and look at the speed of the other party, at this time, the speed of the ironclad train was not fast, it could be said to be very slow.

Their task is to inspect the railroad to see if the rails are intact and whether they have been damaged, although the Eighth Route Army in the Lucheng area has been very quiet recently, but they do not dare to be careless.

After all, the strength of a brigade was lost on this section of the railway, and an attack caused them heavy losses, especially the locomotives and carriages.

Once you cheat, it takes a lot of time and manpower to save it.

So, their patrols are also a top priority!
