Rigushkov grinned and took out his experimental plan and spread the prepared map on his desk.

Yang Mingzhi leaned over and saw that this was a simple map of the region.

"We set up the launcher at this point on the outskirts of the blacksmith village, aimed it at the position of Homnitsch, and fired four shells in sequence at different angles. In this way, we can get four explosions, and then we can calculate the trajectory by the distance from these explosion points to the launch site. ”

"And! We can also use linear programming to calculate what angle of fire should be used to achieve the best trajectory. Yang Mingzhi finished speaking for him.

"Yes, this experiment is very simple, and it won't cause any waves tomorrow."

Yang Mingzhi nodded and continued to ask, "So, why did you choose to use Homnich as a reference?" ”

"Because it's easy to calculate! Comrade Commander, the road between us and the Holmnich station has been opened. ”

"The road is really clear?!"

Since Yang Mingzhi was no longer responsible for Novgomel's political affairs, a lot of miscellaneous matters were handed over to Lyudbalev. Soldiers are only responsible for military affairs, just like the black pottery water cup on this table, Yang Mingzhi doesn't know.

Little did he know that a dirt road from Blacksmith Village to Homnich Station was now open to traffic. It was a rather winding dirt road, and it was deliberately tortuous in view of the fact that the enemy might easily attack along it. The uneven areas were filled with a large number of wooden blocks, and as the climate warmed up, many sections of the road were still flooded by overflowing water, and the workers had to fill in more logs to cover them.

The ruins of Homnich have been given a new lease of life, and the ground is covered with a large number of metal blocks, which are the raw materials for weapons, and it is important to transport the materials back to the blacksmith village for furnaces, and a stable line of communication.

Therefore, the Novgomel City Committee also did a simple survey and calculated the real straight-line distance from the blacksmith village to Khomnich - 41.9 km.

There was no good way to search for iron in the soil, and the mobilized villagers had to filter the soil with a screen made of wire. There are also some villagers who carry hammers to smash the foundations of the ruins, trying to knock out the steel bars deep in the building.

The Soviet Union built the small city of Khomnych (or a small town by Chinese standards) and abandoned the wooden buildings that the people liked to see, and the extensive use of reinforced concrete, which was a symbol of modernity and the superiority of socialism by the Gomel authorities.

The mayor of Novgomel, Lyudbalyov, had an absolute say in this matter, and he gave the order to renovate the city, and he also made some suggestions when digging up the ruins.

At the moment, more than 1,000 villagers are building settlements in the forest outside Homnich because of the need to dig. They and the remaining troops built a military station, and also built a small warehouse.

The villagers also want to take advantage of the right weather to plant potatoes in the open field of the ruins. It's a pity that the land was blown up, and the land that had been polluted by the smoke of artillery fire was very uneasy.

They still cultivated some land and planted roots at the edge of the forest, and many people chose to settle here - after all, the current population of the blacksmith village is about the same as that of Khomnich before the war!

When the metal blocks have collected a certain weight, they are loaded into horse-drawn carts and transported to the blacksmith village by special personnel.

This transport usually takes two days, because even with a relatively stable road, the route to the blacksmith village is not 41.9 kilometers.

The city party committee arranged for the personnel to carry out accurate mapping of the roads of the three collective farms, as well as the hot springs and the Homnichi military station. Each surveying team, through a 100-meter-long hemp rope in their hands, erected a low wooden stake on the side of the road without measuring 100 meters, and when they measured 100 meters, they erected a section of high and nailed a sign on the top of it, which was a milestone.

This work was carried out relatively backward, and when Yang Mingzhi returned from the expedition, the work was nearing completion.

The milestone shows that it is 82 kilometers from Homnich to the village of blacksmiths. The road perfectly avoided the ponds and the large mud ponds, and if it was winter, the ponds would freeze and the horse-drawn carriages would move in a straight line. At first, everyone did not accept this twist and turn, and the convoy of horses transporting supplies had to set up tents and rest on the way.

Based on these factors, Ryguschkov perfectly explains why he did this.

"In the archives of the municipal party committee, on the map of their survey team, all the milestones of the road are marked. The rockets are fired at Homnitch, and we use this kind of map. Once you've decided on the bombing point, draw a line to the nearest road milestone to calculate the straight-line distance accurately! ”

"I see!" Yang Mingzhi was not too excited, he clearly realized that Rigushkov's method had to go through some complicated mathematical calculations, but fortunately, he really didn't need to send someone to measure it himself, just use the ready-made data from the database to calculate it.

He was sincerely pleased: "Well done, we'll do it tomorrow!" ”

……

The time for the rocket artillery experiment was set relatively early, and Rygushkov laid out a plan to launch the first one at about 9 a.m.

Before that, he and his men at the Arsenal had to get four shells and the rails for firing the rocket launchers to the northernmost predetermined position in the blacksmith village.

It's been a busy day, and I'm having a great time talking to that guy in the evening!

Yang Mingzhi dragged his tired body out of the door of Rygushkov's office, and in a slightly haggard tone, greeted several of his guards who were squatting on the ground and gathering to smoke.

The guards led by Abram were startled, and threw their cigarette butts and stepped on them a few times, like straight pine trees standing in a row.

The scene was a little embarrassing, Yang Mingzhi waved his hand lightly: "It's late, disband!" Get a good night's sleep, we have big things to do tomorrow! ”

"Big deal? What's the big deal? Abram sensed the chief's exhaustion and said with concern: "Sir! You're busy, I'll stay with you for a while! ”

"It's good! That's good! Yang Mingzhi sighed, "Let's go, come with me to the headquarters." ”

The moonlight tonight is also very good, with slightly more clouds in the sky, which can occasionally obscure the moonlight. The sky was full of bright stars, with the occasional glimmer of meteors.

After a busy day, the villagers involved in digging potatoes have long since fallen asleep, and the office area of Novgomel is in full swing, and all the warehouses are equally lively.

The telegram was like a machine gun, a plain report from each warehouse. It seems that the warehouse does not plan to report back again after counting some of the harvest. They simply report the harvest of each production group separately, so they are busy.

When Yang Mingzhi came to the headquarters, there were still a few old guys sitting here.

Yevlov and Fomin gathered to drink, and even pulled Yerentina over, the woman was obviously very excited, and the command office was filled with endless women's tongue snapping.

"Hey! Comrades, our general is back......" With a burst of ridicule from Yevlov, Yang Mingzhi joined the "cocktail party".
