The telegram sent back by the Lihai Security Agent Squad in the capital was forwarded by Tianjin Wei and soon reached the joint headquarters of the Dagukou Military Camp.

In the headquarters, a copy was immediately forwarded to the General Staff Office of the Hantang Security Department.

The few people who can participate in the command feel bad, why are the evil forces so good at arousing evil in people? Why, no matter how bizarre the lie, are there many believers? Is it information asymmetry?

But the capital is not the city of Guangzhou, and it must be defeated!

There are places that are different from the city of Guangzhou.

The inner city of the capital is located between the imperial city and the outer city, and the inner city wall is rebuilt many times by the Ming Dynasty on the basis of the city wall of the Yuan capital.

It has a circumference of 40 kilometers, and the inner wall is made of rammed earth, and the inner and outer walls are based on stones, and the upper walls are covered with bricks.

According to the information sent back by the Haian agent team, the inner wall of the inner city is about 10 meters high, the outer side is about 11 meters high, the top thickness is about 14 meters, and the thickness of the wall base is about 19 to 20 meters.

After the Tatar bandit group entered the customs and occupied the capital, the officers and soldiers of the Eight Banners and their families were stationed in the capital, and the Tatar bandit group ordered to occupy the houses in the inner city for the banner people to live in.

The Ming people who used to be in the inner city all moved to the outer city to live.

The inner city is centered on the imperial city, and is divided into four corners and eight directions by eight flags - two yellow flags in the north: the yellow flag is stationed in Anding Gate, and the yellow flag is stationed in Desheng Gate; Two white flags in the east: the inlaid white flag is stationed in Chaoyang Gate, and the white flag is stationed in Dongzhi Gate; Two red flags in the west: the red flag is stationed in Fuchengmen, and the red flag is stationed in Xizhimen; The two blue flags are located in the south: the blue flag is stationed in the Xuanwu Gate, and the blue flag is stationed in the Zhengwen Gate.

There are a total of nine city gates in the inner city, which are distributed along the second ring road of the world, namely Zhengyang Gate, Chongwen Gate, Chaoyang Gate, Dongzhi Gate, Anding Gate, Desheng Gate, Xizhi Gate, Fucheng Gate, and Xuanwu Gate.

If we add to this the policy of non-intermarriage between the Tartars and the Ming, it can be seen that the Tartar bandit group came to colonize at all, and I really don't know what it has to do with the so-called national integration that some people say.

Then there is no psychological pressure to attack the so-called inner city or imperial city.

Those who come out to mix, sometimes they have to pay it back, they can quietly retreat after doing so much evil, and there are even those who wash the floor, that is not a normal society.

Impunity for sin is the greatest insult to goodness!

Minister Wu Jianqiang agreed to the request of the Dagukou Joint Command and concentrated the use of siege rockets in the direction of attacking Shanhaiguan and Shengjing to the capital.

Since they think they are colonizers, it is time to name them.

The intelligence of the Hai'an agent team verified this, and all the families of the Tartars were gathered in the inner city and the imperial city, and the Ming people were never allowed to enter casually, especially now, they had driven out the Ming merchants who were not many in the inner city.

They didn't think there would be a weapon that could hit four or five kilometers away and fall accurately, right?

Now, Hantang Group's technology on solid rocket engines has been upgraded.

This is mainly because of the forced artificial rainfall technology, Hantang Group is really convinced of this Xiaoice period, even in the Taipei area can have drought during spring ploughing production!

Now there is a song that has been popular in Taipei, "Come to Taipei to See the Rain in Winter", but for that year, this song was very fake.

The deep-hole black fire/powder pillar rocket engine was eliminated in a rage-

"Don't think about saving money, save trouble! It's been five years, and you're really embarrassed to buy the black fire/medicine processed by other people, and you can make do with it after a simple processing?!

Don't engage in black fire/medicine or monobase!

You have to have the big picture in mind!

We now need artificial rain equipment with higher and longer legs!

God doesn't give us rain, we make it ourselves!

Man is the sum of all the forces of nature!

If you want a liquid engine, at least a double-base solid! ”

Liberal arts students, especially those with some reading ability, are terrible; The scariest thing is that if a liberal arts student has a little bit of hands-on ability, it is scary!

Liberal arts students roared, and science and engineering students were tired like dogs!

For example, Secretary General Yang Youxing can use a bull head lathe to give Manager Shen Qianqian a few belt buckles and the like, show off these two people, and tell others everywhere that he is invincible in machining - Director Wu Di saw it and smiled generously, it doesn't matter, it can't compare to the skills of his apprentice, but it is not easy for a street writer.

Director Mu Mu is a cautious eye, he can't get used to the behavior of the two of them, and when he turned around, he gave his little daughter-in-law a few belt buckles, and the patterns on them are all precise and meticulous to the highest level of bull head lathes, almost all of them are at the level of silk meters.

Take it for show, we're unique.

But a word from his little daughter-in-law almost him off!

"It doesn't seem to have her atmosphere!"

, he's not big, okay? Can he control it?!

But the thought of explaining too much technology made him admit it.

Chairman Wu Dapeng, a big liberal arts student, spoke strongly, he said: "Technicians, sometimes you can't use it, you must keep pace with the times, learn the scientific concept of development, put down the burden of cost and other burdens, and stride forward!"

We must be anxious about the people's urgency and deal with nature with leapfrog development! ”

Polytechnic students are afraid of such things - never say what specific things you want you to do, anyway, you can understand it yourself!

Lin Shengli, the director of the Red Star Military Factory, frowned and brought in a few senior technicians to get a liquid engine, which is, and changed the black fire/medicine engine that is obviously adapting to the current situation to a double-base type.

A senior technician said angrily: "What can be solved with 2,000 horse tickets, do you have to make 15,000 horse tickets to solve it?" It's a fart to look cool! ”

Another senior technician said: "Forget it, don't talk about it, it's rare that they can still distinguish between single and double bases, give face, anyway, they are the ones who make the budget-"

"There's my stake in this, too—"

"Okay, don't count this little account, it's not ordinary money anymore, it's just a data at this time-"

"Then you can't cross too far, aren't you afraid of getting your balls?"

"No, no, isn't that tiring yourself? What we can't find on the information is all changed to scientific names, and they think it's tall! ”

Everyone immediately agreed.

Solid rocket engines are chemical rocket engines that use the energy and working fluid of solid substances as propellants.

The solid propellant is ignited and burned in the combustion chamber to produce high-temperature and high-pressure gas, that is, the chemical energy is converted into heat energy; The gas expands and accelerates through the nozzle, and the heat energy is converted into kinetic energy, which is discharged from the nozzle at a very high speed, creating thrust to propel the rocket forward.

Finally, the Red Star Military Factory handed over a report on the development and production of the DoubleBase Propellant solid rocket engine.

In the proposal, they introduced the characteristics of a DBP solid rocket engine with a theoretical specific impulse of 1660~2150 N/kg, a density of 1.55~1.65 g/cm3, and a danger level of 1.3.

The DBP formula is mainly composed of nitrocellulose and NG, with ZNO and MGO as additives, and the molecular structure of the two main components contains flammable agents and oxidants, and the two additives can increase the vitality.

The nitrocellulose is partially dissolved in NG, volatile or non-volatile solvents and other additives are added, and plasticized to become a homogeneous object, which can be made into different shapes of medicine columns by stretching molding process.

The advantages of DBP type are uniform column texture, uniform structure and good reproducibility; It has good combustion performance, and the combustion rate pressure is very small; Good process performance; It has a low characteristic signal, and the exhaust is less smoke or no smoke; It has good stability, mechanical properties and anti-aging properties at room temperature; The raw materials are widely sourced and economical.

The tail can easily hit the Mach disc!

The disadvantage is that the energy level and density are low, and the mechanical properties deteriorate at high and low temperatures.

But the DBP type is especially used for small-sized solid rocket launchers up to thirty kilograms, with a vertical range of up to two kilometers and a solitary line range of up to ten kilometers.

Thirty kilograms! Twenty kilograms will blow up the sky!!

Chairman Wu Dapeng signed the budget request with a stroke of the pen, and the liberal arts students on the Internet were full of passion, take a look, don't force them, they are the practice of the old lady with small feet!

But the knowledgeable science and engineering students only echoed a few words, and privately asked whether it would affect the production of Nada's industrial-grade explosives.

Director Lin Shengli said: "It's a little bit - forget it, the overall situation is important, use more black fire/medicine to open mines, save money." ”

Well, there was nothing unpleasant about the fight.

Of course, Director Lin Shengli will not use the DBP type on the bazooka, the tail flame is too big, and the black fire/medicine type is still applicable, but no one cares about this.

Those who are good at face engineering must be from a liberal arts student, and they don't need to be checked, and the accuracy rate is extremely high.

The news of the Dagu Barracks' joint command requesting the concentration of rockets was also known to the liberal arts students, and they are not novices, and they are not from pirated backgrounds, so of course they will not spray indiscriminately, and nonsense is definitely not okay.

On this night, Secretary General Yang Youxing said to Manager Shen Qianqian: "My dear, of course we will regard people as above all else, but those cultural relics - do we try our best to protect them?" ”

Manager Shen Qianqian was painting evening makeup in front of the dresser, she smacked her lips at herself in the mirror, and saw how easy it was for young people to draw makeup, with just a few strokes, this lip shape came out.

Manager Shen Qianqian said lazily: "My dear, it's too high to ask for others for such a thing, you'd better not come out - that Mayor Bao Wei doesn't love cultural relics, oh?" ”

"That's right!"

Secretary-General Yang Youxing snapped his fingers and said, "The city wall and the buildings inside are more than 200 years old, let him rush to the front and say - I'm too shrewd!" ”

Secretary General Yang Youxing succeeded, and Mayor Bao Wei really did not agree with the wanton bombing, and he sent a telegram to explain his attitude.

It's okay to blow up the inner city, try to avoid the city walls, okay?

Don't bomb the Imperial City, everything in there can be in the museum - at least a hundred years old, right?

The last step, isn't that bad?

Director Lin Shengli finally became a little angry, and he said on the Internet: "Why are there so many/faults?!" What if it's hundreds of years old? I'm bending down to pick up a stone for hundreds of millions of years, can you believe it? ”

For such erroneous remarks, Secretary General Yang Youxing smiled and went down, and he made Director Lin Shengli speechless in a few words.

Cultural relics can't be compared with stones, whether the national culture is good or bad, it must always be inherited, right?

There's a kind of thing you say that everything blows up and starts all over again-

Mayor Bao Wei later learned that Secretary General Yang Youxing agreed with his views in this way, and he was so happy that he often invited him to dinner and clubbing.

Of course, that's another story.

Tianjin Weiqian Finger Center.

The three squadron leaders, Yue Xiao, Wang Cheng and Wang Hongli, were also discussing at the meeting.

They didn't encounter the 1860 Monk Grinqin fools in that world, they didn't even concentrate cavalry to attack!

Instead, they broke up into several - they became nomadic hunting parties.

Thank you for the support of the Platinum Alliance Leader Qingfeng Mouse, the Gold Alliance Leader MM Daddy, the Gold Alliance Leader Mei Lezhi, the Gold Alliance Leader guozhiyin, and the Templar Feather.
