Early the next morning.

When Zhu Daolin and Duan Deming drove into the provincial capital, it was raining in the sky, and the temperature quickly dropped from 17 degrees Celsius to 11 degrees Celsius.

When the big jeep drove into the rented warehouse in the western suburbs and stopped, Duan Deming's two sisters-in-law invited a distant relative who came to see the warehouse to greet him with a boy about ten years old, and while wiping his nose, he led Zhu Daolin and Duan Deming into the four warehouses inside, and inspected the neatly stacked bags of rice, corn, and various vegetables and crop seeds.

After carefully inspecting the circle, Zhu Daolin asked with satisfaction: "Brother Peng, in addition to the 300 tons of black rice, red rice, corn and peanuts in the row of houses in the west, do the seeds of rice, corn, soybeans and mung beans in these four warehouses add up to 150 tons?" ”

Brother Peng, who was honest, hurriedly replied: "160 tons...... If you add in the 20 barrels of green vegetable seeds, 5 barrels of pepper seeds and 12 barrels of melon bean seeds on the shelves against the wall in the back room, a total of a little more than 162 tons, I have counted it four times, and I can't be wrong. ”

Zhu Daolin thanked Brother Peng: "Brother, can you get a few tons of high-yield potato seeds and sweet potato seeds?" ”

Brother Peng said with a smile: "There are many in our hometown, if you want to buy it, you can buy it now...... If you want, you are guaranteed to get two high-yielding potatoes and two sweet potato seeds within three days.

"You're going to take the seeds with you this time?" Duan Deming was quite surprised.

Zhu Daolin nodded: "There are a lot of rats in this place, so it would be better to lose less if you transport them away as soon as possible, so let Brother Peng go back immediately and help me buy some potatoes and sweet potato seeds...... If it can be shipped back the day after tomorrow, it doesn't matter if I wait another day. ”

Brother Peng, who had not returned to his hometown for a long time, immediately said: "The shuttle bus from the provincial capital to our township runs every two hours, and you can get home after lunch quickly, and you can buy it back before dinner the day after tomorrow, three or five tons of sweet potatoes and potatoes are enough for a farm vehicle." ”

"How much does it cost to have 3 tons of high-yielding potatoes and 2 tons of high-yielding sweet potatoes?" Zhu Daolin asked.

Brother Peng thought for a while: "Two kinds of high-yield potatoes are more expensive. Several perennial households in the village are estimated to cost 1 yuan per catty2, several sweet potato seeds are cheap, 8 cents on the line, our township is 250 miles away from the provincial capital, and the freight is probably 600 yuan. ”

Zhu Daolin immediately decided to come down, and especially instructed Brother Peng to spend even more money. I also had to pack the potatoes and sweet potato seeds in a sack, and then asked Duan Deming to bring Brother Peng with him, first go to the bank to withdraw money, and then send Brother Peng and his son to the bus station.

Duan Deming thought for a while: "Okay, cousin, you close all the doors and windows, there is no problem in this place for a day, just come back early tomorrow." ”

An hour later, Brother Peng, father and son, who were carrying 13,000 yuan in cash in their arms, successfully got on the minibus bound for the southwest countryside. Duan Deming and Zhu Daolin drove to the sales department of the gas company and purchased 600 brand-new liquefied gas cylinders produced by regular manufacturers.

Due to the lack of inventory, the sales manager explained that it was necessary to mobilize from other branches to ensure that the goods could be picked up at 2 o'clock in the afternoon.

After finishing the purchase of cylinders, there is still half an hour before getting off work at noon. After Duan Deming used his mobile phone to contact his old friend, he drove the car to the Shuicheng Iron and Steel Group Sales Company in the provincial city. Tell Zhu Dao Linshuicheng Iron and Steel has always produced and manufactured various pipes for rocket artillery and mortars, and has been the steel pipes for many military enterprises in Guizhou Province for decades.

Duan Deming's old friend is the deputy manager of the sales company, and he was very happy to see Duan Deming, and he said that he would invite Duan Deming to have a drink.

Evening. Zhu Daolin and Duan Deming led two ten-ton trucks to transport 600 cylinders and high-quality steel pipes worth 1.48 million back to the factory.

At four o'clock in the afternoon of the next day, five mortars and two sets of rocket artillery samples processed from cylinders were successfully completed.

Zhu Daolin and Duan Deming called a few masters with great interest. The two mortars were pulled by cart to the valley range to the south and set up, and the two veteran technicians prepared the projectile and the disc-shaped simulated shells wrapped in yellow mud, and began the test firing according to the normal charge previously calculated.

With the muffled sound of "tom" and "tom," two disc-shaped "cannonballs" weighing 8 kilograms each flew out in a burst of intense gunpowder smoke and blazing flames, flew at an angle of 40 degrees and flew more than 200 meters, then drew a downward arc, smashed heavily into the ground, stirred up two clouds of dust, and broke and scattered after rolling a few times.

The two masters guarding in front of the landing point quickly raised their voices and reported loudly: "About 325 meters!" ”

"330 meters from my side!" Another shouted.

Duan Deming discussed with the two old technicians for a while, started the second charge, and told Zhu Daolin, who was full of smiles, as he worked:

"The amount of propellant just now is 0.8 kilograms, this time I tried to load 1.2 kilograms, and basically reached the maximum charge, if it weren't for the thick wall of the cylinder tube and the strong base, I really didn't dare to do it."

"What is the total weight of the whole gun?" Zhu Daolin asked.

The old technician on the side immediately replied: "The barrel plus the adjustable fixed base, a total of 72 kilograms, after the disassembly, two people can carry it on their backs, we will redraw the design and exploded drawings, as well as the calculation parameters of the propellant and the projectile package, go back and fill in the experimental results, and give you a copy to take away." ”

"Great! Thank you! ”

Zhu Daolin was sincerely grateful, and an evil thought arose in his heart: It would be great if these two precious technicians were included in the King Kong circle and brought back!

The next eight rounds of experiments were satisfactory.

8 kg kits were fired at the maximum charge, the firing range was between 420 and 430 meters, the mortars and bases were intact, and the impact point dispersion was within 20 meters.

Duan Deming and the two veteran technicians agreed that as long as the medicine bag is more well-made and has better airtightness, the range and accuracy can be increased by about 8% to 10%.

The only regret is that because the manufacture of rockets is quite troublesome, this time it is impossible to carry out test firing, but Zhu Daolin does not have many regrets, the production of rockets is very simple for him, after bringing the rocket artillery back, he can repeatedly test fire, after obtaining relevant data, he can work out a simple and reasonable fixed charge and launch procedure.

At 8 p.m. that night, five mortar guns with adjustable fixed bases, two sets of quadruple and six-pack rocket launchers, and four second-hand machine tools packed in large wooden boxes were loaded into old containers and delivered to the road north of the bridge, along with 7,000 steel helmets, 2,000 flintlock pistols and 50 wooden crates of various machine tools in other three containers.
