Lin Yuan thought to himself: "If the Japanese load the large-caliber heavy artillery on the car and then load the car on the railroad tracks, won't it solve the problem of transportation!" ”

In Lin Yuan's time, the rail cannon was widely used in the First World War, because the road could not bear the weight of the heavy artillery, and because the mobility of the heavy artillery was extremely poor, so all countries put the heavy artillery on the rails, and there were sleepers and sand piles of roadbed under the rails, so they could bear the weight, and they were driven by a locomotive, so they could maneuver quickly.

Britain, Germany and France all developed their own railroad guns, the most famous of which was the "Paris Cannon" developed by Germany with a range of up to 130 kilometers, which could pass over the heads of the French army and blow up to Paris.

However, due to the long range and the lack of automatic navigation devices, the deviation of this heavy artillery is extremely large, so the shells fired by the Paris cannon can rarely reach Paris accurately, and many Parisians do not even know that they have been bombarded by this "famous cannon" until the end of the war.

Seeing that Lin Yuan didn't speak, Liu Dart panicked for a while, thinking, "Is there something that Lin Shuai doesn't know?" Liu Dart hurriedly asked, "Lin Shuai, what should we do?" ”

Lin Yuan said: "Pass the order, this is a new weapon of the Japanese army, but don't worry, I have already thought of a way to solve it, so that the distance between the teams will be increased by another hundred meters!" Travel at the original speed. Lin Yuan actually set fire to the dead end of the Japanese railroad artillery, and he knew that the accuracy of this kind of long-range artillery must be very poor, so he ordered the distance between the departments to be widened, which could effectively avoid casualties.

What Lin Yuan didn't expect was that a shell landed at the front of his troops, and from a distance he saw more than a dozen soldiers being pushed up by the shock wave generated by the explosion, and there was chaos in front of the team, Lin Yuan and Liu Dart hurriedly rushed over.

The shells landed less than two hundred meters next to the team, which was covered in blood and minced flesh, and since the site of the explosion was at the very front of the team, the whole team stopped.

Liu Dart shouted at the captain, "How is it? How many brothers did you hurt? ”

There was no answer in the team, Liu Dart shouted twice, and a sentry commander stood up, with tears in his eyes, and said: "The captain was killed by the explosion, a total of eleven brothers were killed and seventeen were injured.

Lin Yuan saw that everyone had fear on their faces, and stepped forward and said, "Don't panic, these shells are just a trick of carving insects, and they are not worth mentioning in front of Ben Shuai, don't stop, keep moving!" ”

When everyone heard Lin Yuan say this, their panic decreased slightly, and they continued to march, Lin Yuan knew that such a heavy artillery as Lu Dao would have a long preparation time after firing once, so although the enemy's shells shot far, they could not achieve the continuity of firepower, if you calculate the number of explosives it can deliver per unit of time, such heavy artillery may not be superior to the 70mm artillery that the Japanese army was equipped with before.

If it was the Qing army before, it would have been scattered as birds and beasts long ago after being hit by such heavy artillery, but now Lin Yuan is in the team, so the Qing soldiers are like taking a reassuring pill, and everyone has such a thought in their hearts: The Japanese are like monkeys, no matter how noisy they are, they can still run out of the palm of the Buddha!

What the Qing soldiers didn't know was that Lin Yuan also had a lot of questions in his heart at this time, not only about the rail cannon itself, but also about what the Japanese army used to correct the shooting of the rail gun?

Now it seems that the observation post on the high ground on the east side of Xiaowang Village that Chen Fei attacked was used for indirect targeting of these rail guns, but hasn't Chen Fei destroyed the equipment of that observation station?

Lin Yuan planned to mobilize the drones on the Beijing ship to reconnoiter and locate the Japanese rail gun, and then consider destroying it, at this moment, Chen Fei's voice came from the communicator: "I found that the Japanese army has built a railway track near Zhangyi Station, and there is a huge gun carriage on the railroad track, and the caliber of the gun is estimated to be more than 400 millimeters. ”

Lin Yuan thought to himself: "It seems that it is really a rail cannon!" He asked, "Where are you now?" ”

Chen Fei replied: "I am now about four kilometers away from the rail cannon, where I am is on a high ground, from here you can see that there are three rail cannons, just completed a round of firing, now the Japanese army is cleaning up the residual gunpowder in the barrel, and more than a dozen soldiers are carrying the cartridge bag, it seems that the second ** shot will be carried out in a while." ”

Lin Yuan asked again, "Can you strike at it?" ”

Chen Fei replied: "I don't think it's possible, the Japanese army's defense within a kilometer is very tight, and my range can't reach it." ”

Lin Yuan thought for a while and said, "All your tasks must be based on the premise of ensuring your own safety, since the enemy is well defended, don't attack reluctantly." ”

Lin Yuan asked again, "Didn't you destroy the observation post in Xiaowang Village?" How did the Japanese correct their shooting at such a distance? ”

Chen Fei said with a smile: "I know that the small reconnaissance plane is a good friend of the artillery, and maybe the Japanese have already invented the aircraft." ”

Lin Yuan's heart moved when he heard this, it's not that there is no such possibility! The breakthrough of engineering technology is like this, it is not like the breakthrough of basic scientific theory, it requires genius and excellent thinking, such as quantum mechanics, relativity, many breakthroughs in engineering technology are natural, other fields develop to a certain stage, a certain engineering technology will naturally appear, such as airplanes, when the internal combustion engine, aerodynamics and other aspects have accumulated to a certain extent, even if there is no Wright brothers, there will be others who invent airplanes!

And his own crossing is precisely to create an excellent opportunity for the breakthrough of engineering technology! In this era, everything needed for an airplane is already available, and when the carrier-based aircraft on the Beijing ship soars in the sky, it has already inspired countless engineers and scientists!

At this moment, the crowd could only hear bursts of exclamations, Lin Yuan looked up, and saw many soldiers stopping, looking up at the sky, and pointing with their fingers.

Lin Yuan followed everyone's gaze and looked towards the sky, only to see a floating dot appear in the sky, gradually, the dot became clearer and clearer, Lin Yuan raised the telescope in his hand to look, only to see a huge cylinder floating in the sky, which was written in Chinese characters: Kill the person of Guangzhi!

Lin Yuan adjusted the telescope to the bottom of the cylinder, and saw a huge hanging basket hanging under the cylinder, and there were people on it, but what those people were doing was too far away to see clearly.

Seeing this thing, Lin Yuan instantly understood how the Japanese corrected the shooting of artillery!

It turns out that the Japanese came up with an airship!

Airships are much simpler than airplanes, to put it bluntly, it is similar to the principle of hot air balloons, in a huge lightweight cylinder filled with gas less dense than air, generally using hydrogen or helium, helium in this era has not been discovered, so it will not be produced in large quantities, so the Japanese should use hydrogen.

When Lin Yuan saw that it was an airship, his heart relaxed a little, and he thought that the Japanese had made the plane out!

Just when Lin Yuan was complacent, another bad situation happened.
