Wang Lei didn't know what happened in Yan'an. Wang Lei www.biquge.info after sorting out the collection room, he returned to his room and fell asleep, and then slept until he woke up naturally the next day......

......, waking up naturally is just Wang Lei's plan to go to bed. In fact, Wang Lei was woken up by the piercing air defense sirens just after dawn the next morning.

Wang Lei was extremely reluctant to get up from the bed and open the curtains of his room. Through the window, he saw the slowly rising sun, the cloudless sky, and a few small black dots in the distant sky in the reflection of the morning sun, and a little fire flying out of the horizon. This was the anti-aircraft guns of the Japanese army and the independent regiment, which was the main reason why the air defense sirens sounded in Ping'an County.

At this time, the Japanese planes were flying towards the county town of Ping'an, and although the independent regiment wanted to stop it, the fire from the anti-aircraft shells was still some distance away from the planes in the sky.

Wang Lei's anti-aircraft gun for the independent regiment was an Erlikon 20mm cannon, although the maximum firing range of this cannon was much higher than the original under the improvement of Bai Xue, but the plane flying in the sky really did not fail to hit without reducing the altitude. So now the Japanese planes are still at a fairly high altitude, at least at an altitude of 3000m, but the problem is that they are very close to Ping'an County, and they are not reducing their altitude at this time, how can they bomb Ping'an County?

In this era, there is no precision guidance, and at the current altitude of Japanese aircraft, it is completely impossible for them to carry out precision bombing.

Wang Lei still doesn't know what these Japanese planes are for! Is it really sightseeing at the high altitude in Ping'an County? And then "pooping" everywhere?

……

……

With a roar, the Japanese planes soon reached the sky over Ping'an County, and at an altitude of nearly 2,500 meters, several Japanese planes began to drop bombs.

At this time, the aircraft did not have as much technological assistance as later generations, and the altitude and speed of the bomb could not be too large. The higher the faster, the worse the accuracy. The most standard posture is: enter the combat zone - slow down - when you reach the target area - dive - drop the bomb. The whole process requires the body to remain stable, drop the bomb and then quickly raise its head to accelerate out of the combat zone.

Although it is said that airplanes in this era can also drop bombs at high altitudes, it is difficult to say the accuracy, because it is difficult to predict the direction of the wind at high altitudes, and there is no computer assistance, so the bombs dropped by airplanes completely depend on the experience of pilots. With such a high altitude and unpredictable winds, even if you get an ace pilot, you can only try your luck completely!

In this regard, the aerial bomb that blew up the toilet and the toilet that has been bombed absolutely have something to say. Although judging from the crater at the city gate, the Japanese dropped all small aerial bombs, but no matter how small they were, their value was already higher than that toilet, but this aerial bomb blew up the empty toilet.

……

……

The Japanese planes came and went quickly, and in just a few minutes they completed the bombing of Ping'an County! This time, they dropped dozens of small aerial bombs at high altitude and successfully blew them up, and Wang Lei saw that a bomb fell into a family's haystack, and then blew up the grain and grass that they were going to feed the cattle. Don't talk about anything else, this family will have to find cow grass for the cattle from scratch, you see that it will be troublesome for others!

As for the personnel, there should be no casualties, and at the first moment the air raid siren sounded, the residents of Ping'an County either hid in nearby air-raid shelters or directly in their basements. Although the air defense capability of the basement is very average, it is basically safe for the Japanese not to use heavy aerial bombs.

However, the Japanese planes were also really daring, and five bombers flew into enemy airspace without any fighter cover. Of course, looking at the bombers flying arbitrarily in their own airspace, the independent regiment really has no way at all, and the best way to deal with the air force is the air force, but now the Eighth Route Army does not even have its own planes, how can it become a formed air force!

Wang Lei watched the whole process of the plane bombing in his room, without the slightest intention of dodging.

It's not that Wang Lei is bold, but that the building materials used in his home are all high-strength materials. Ordinary bombs, no matter how many you have, don't even want to destroy the structure of the house. And at the beginning of the design of the house, it was considered to prevent burning, radiation, shock waves, etc.

It can be said that Wang Lei's house is completely built according to the standards of military bases before the energy era, except for the appearance.

Wang Lei felt a little regretful, but he didn't put it when he thought it was strange to put a missile launcher on the roof, otherwise Wang Lei could have knocked down these guys who were showing off their might in the sky.

Although a few electromagnetic cannons installed in the house can also do all this, but now this electromagnetic run needs a lot of electricity to hit the plane in the sky. For example, in Ping'an County, this small power plant cannot meet the firing conditions of the electromagnetic cannon even if it is fully powered. Now the electromagnetic cannon can only be fired by underground batteries, but when the battery was designed, it was considered that the electromagnetic gun was only used for emergency use, so the battery capacity only supported 4 rounds per gun, and then there was a long storage period.

However, although the main cannon can't be used, some secondary guns can still be used, although it is said that it can't hit planes at an altitude of several kilometers, but it is no problem to hit some shells that may fall around Wang Lei's house. Some shells that might have landed near Wang Lei's house were hit by a ball of light and turned into powder.

Wang Lei's electromagnetic cannon is not an electromagnetic cannon designed in the 21st century, and the electromagnetic cannon at that time used electromagnetic firing technology to launch projectiles. However, the electromagnetic cannon used by Wang Lei imitates the ball lightning in nature, and what it emits is a ball-shaped high-energy electric ball. However, because it contains high-frequency electromagnetic pulses that can destroy electronic equipment, it continues to be called electromagnetic guns.

However, there are still side effects, because of the emitted electric balls, so even during the day, you can still clearly see the obvious electric light. Although the surrounding people hid when the air defense siren sounded, in the past few days, the surrounding people have started to spread rumors that Lei Gong blesses this alley, and obviously someone saw the electric light emitted by the electromagnetic cannon!

In this regard, Wang Lei didn't pay too much attention to it, and saw what uncontrollable consequences a few ball lightning bolts could cause. According to statistics, most of the extraterrestrial events in later generations were made by the research institute hidden in the annex, but no one has seen these high-tech things.

Wang Lei now gradually understands the reason why Bai Xue asks for the secrecy of science and technology - the sustainable development of civilization! After all, if you suddenly come up with something that takes them several generations to figure out, it may make people lose their desire to explore, so how can society develop, Wang Lei has a thousand years of technology, but what about a thousand years later? Is society just going on? But human beings are complex animals, the society composed of people is not so simple, the development of science and technology also reflects people's desires to a certain extent, once the development of science and technology stagnates, the social problems caused by human excess desires will be a terrible storm, and even regression is not impossible!

This is also why since the establishment of the Arsenal Research Laboratory, Bai Xue has never directly interfered in any scientific research projects in the institute, even if this scientific research has stalled due to a small mistake. Bai Xue is to maintain and maintain the scientific research spirit and atmosphere in the institute, so that the arsenal can continue to develop benignly. Otherwise, if you get used to relying on white snow, it may cause the arsenal to be crushed when it encounters a problem that white snow can't solve in the future!

However, you still have to use your own technology, and others can't use it when they see it! It's a big deal, a few more urban weirdos! Wang Lei is now very open to these.
