"Stop the civil war and unite to resist Japan!"

"I'd rather die than be a slave to the country!"

Zhou Hexuan sat in a rickshaw and walked through the cold streets of Beiping. Hundreds of students marched on the streets, holding signs and shouting slogans, and citizens along the way stopped to watch.

The parade here in Peking is a small fight, and the real big parade is on the Nanjing side.

At the beginning of the month, thousands of students from various schools in Peiping lay on the tracks for three days and three nights, forcing the railway bureau to set off for Nanjing and join thousands of students from Shandong in a joint demonstration.

When the students arrived in Nanjing, they were divided into "radicals" and "moderates". The radicals took advantage of the Central University and the moderates took advantage of the Jinling University to march in the streets every day, and the Nanjing Nationalist Government was in a state of confusion.

But at this time, college students are the pride of the sky and cannot be easily offended. While reassuring, the Nanjing authorities took care of them: each person was given two military blankets, two meat, two vegetarian and one soup for each meal, plus bread, butter and biscuits for snacks. If you have to visit the Sun Yat-sen Mausoleum and tour the city and have no time to go back to school for dinner, you can also eat for free at any restaurant in the city with the meal coupon.

At first, the students threw away all the food they had eaten, but later it was estimated that they did not have enough money, so they had to reluctantly accept it.

Just three days before Chang Kaishen announced his resignation, he personally appeared (since 918) to speak with the marching students for the 18th time. The "moderate" student group was appeased, and after a day of visits organized by the Nanjing authorities, the "radicals" continued to march and demonstrate.

Two days later, thousands of students from more than a dozen schools in Shanghai rushed to converge, and middle school and university students from Hangzhou, Anqing, Wuhu, Suzhou, Wuxi, and other places also came one after another, and the total number of protesting students exceeded 10,000 again, and all of them lived in Sun Yat-sen University.

On the morning of Chang Kaishen's announcement, the students first went to the Ministry of Foreign Affairs and smashed the Ministry of Foreign Affairs' signs, cars, desks and chairs, doors, windows, and filing cabinets. Then the students went to the Central Party Headquarters of the Kuomintang, where the Fourth Plenary Session of the Kuomintang was being held, and the students met with the bigwigs of the Kuomintang.

The students clamored for Chang Kaishen to come forward to express his attitude, and Lao Jiang sat in silence, looking like he was watching a good show—he had just been forced to announce his resignation from the post of president of the country and commander-in-chief of the three armed forces, and this kind of thing was no longer under his control.

Chen Mingshu, commander of the Beijing-Shanghai garrison, and Cai Yuanpei, a bigwig in the education sector, stood up, the former was responsible for law and order, and the latter was responsible for persuading students.

Cai Yuanpei didn't say a few words, and was caught by the students along with Chen Mingshu, and the guards next to him hurriedly shot into the sky to warn. The gunshots completely angered the students, and a female student named Xue Xun from the Beiping Art Institute slapped Cai Yuanpei in the face, and other students began to beat them one after another.

After beating Chen Mingshu and Cai Yuanpei, Xue Xun shouted the slogan of "capture Chang Kaishen alive" and rushed to the party headquarters, and met Zhang Daofan, the minister of propaganda, Chen Guofu, the head of the organization department, and others. As a result, the Kuomintang bigwigs fought with the students in the aisles, smashing tables, chairs and benches against each other, and shattering glass and chandeliers.

There are many opinions about this farce, and it is difficult to sort out the clues.

But there must have been many people on both sides who were injured, the commander of the Beijing-Shanghai garrison was knocked unconscious by the students, Cai Yuanpei was taken hostage by the students, and the most ferocious students were also arrested.

When Zhou Hexuan saw the news in Beiping, he couldn't help but imagine Chang Kaishen's reaction at that time. Lao Jiang should be gloating, let you unite to force Lao Tzu to go into the wilderness, Lao Tzu will not play with you now, you will deal with it slowly.

"Sir, it's here!" The rickshaw driver reminded.

This is a wasteland between Peking University and Xishan, Zhou Hexuan took Sun Yongzhen to get out of the car and walk, and immediately several students came to greet him.

Zhou Hexuan smiled: "How did the experiment go?" ”

"Please Mr. Zhou to test the results." A leading student said happily.

These are all classmates from the scientific research department of Peking University, and Zhou Hexuan used his memory to make some things and let them help carry out research and development experiments.

I saw some messy things in the open space, including molds, stoves, wood, charcoal, bellows, and gunpowder...... Fragmentary, at first glance, it is the lowest kind of small workshop utensils.

The students quickly got their hands up and a small iron furnace was erected. The outer wall of the furnace is made of thin iron sheets, and the lining is mainly coated with clay mixed with water, with a little refractory material added to it.

The two students worked together to connect the iron furnace to the bellows, and then began to light the charcoal to make a fire to warm up. When the charcoal at the bottom of the furnace was all red, the students began to add scrap iron to the furnace, sprinkling a little limestone with each layer of iron, to increase the fluidity of the molten iron and to facilitate the slag removal later.

About 15 minutes is the most, the molten iron has been burned and it is ready to be cast.

While the molten iron was being boiled, another student had already made a mold. The mold is a mixed sand mold, which is made of 75% sand, 15% clay, 6% sawdust and 4% water, evenly stirred and poured into the sand box, and dried by charcoal fire.

The students first preheated the mold, then applied oil to the mold, and finally poured molten iron into the sand mold, and the shell of a grenade was quickly formed.

At the same time, two other groups of students were making the wooden handle of the grenade and the fire-pulling device.

The handle is machined on a homemade lathe, which is made of wood, with only some key parts made of steel.

Once all the procedures are in order, the next step is to charge. Load the black powder into the cartridge case with a paper bucket, tamp the gunpowder with a wooden stick, and then press it out of the detonator chamber with a wooden stick.

Then install the fire-pulling device, connect the fire-pulling rope and the fire-pulling tube, put the fire-pulling device in the bullet handle, draw the fire-pulling rope from the corresponding end, and then tie the fire-pulling ring. In order to fix the fire-pulling device, it is necessary to plug the wire or cotton around the perimeter and then inject a fixative (asphalt or paraffin) to allow it to cool.

The final step is to assemble the wooden handle and cartridge case, which can be sealed with white wax to protect against moisture if long-term storage is required.

It only takes 50 minutes to make a grenade, and if you have enough manpower, you can make multiple grenades at the same time.

This complete set of grenade-making equipment has a well-known name in later generations - the back of seven people!

When the enemy strikes, seven people will be able to transfer with the equipment on their backs. And the material is extremely coarse and common, if there is no charcoal and charcoal, you can even use corn cob to burn charcoal instead.

This thing was invented by a certain militia member of the Republic, and it was later printed in a book and vigorously promoted it.

As long as they are literate and intelligent, they can rely on the methods described in the pamphlet, using scrap iron, wood and black powder, to produce low-cost and large-scale home-made grenades, which are very suitable for guerrillas behind enemy lines.

"Try the power!" Zhou Hexuan said.

A student pulls the fire rope, and the tail of the grenade quickly smokes, and after being thrown for a few seconds, it explodes with a "boom".

Zhou Hexuan ran over to check the situation and found that the power of this thing was very small, and even the bullet shell was not completely shattered, and the iron shell was split into four or five pieces and scattered all over the place.

After all, there is no good goods cheap, and it is enough to give it to the guerrillas.

Zhou Hexuan is going to print hundreds of copies of "Seven People's Back" and let people secretly take it to the Northeast, and the anti-Japanese volunteers over there should like it very much. Surrounded by the Japanese army, it was difficult to transport donations and materials, and what those anti-Japanese volunteers needed most was this kind of rustic "military technology".
