The maidservant girl didn't go in for a long time, and Wen Po hurriedly came out of the room to see Wang Kunjun, and asked cautiously: "What are the instructions for the old man to be called outside?" ”

Wang Kunjun forcibly suppressed the anxiety in his heart and asked, "It's been more than three hours, why hasn't the child been born yet?" You tell me the truth, is there something big wrong? ”

Seeing that Wang Kunjun's face was not good, the stable woman hurriedly explained: "If you go back to the staff, sometimes it takes some time for a woman to give birth to a child. Madame, she is weak, so it will naturally be more difficult to give birth. However, with the experience of the old body, it should not be a difficult birth. The old man estimated that at most there would be another hour. ”

Hearing Wen Po say that Han Qingwen was not a difficult birth, Wang Kunjun's heart relaxed a little. He waved his hand and asked Wen Po to continue to deliver the baby, while he kept circling in the middle hall, anxiously waiting.

About another hour passed, and at 7:36, the long-awaited baby cry finally came from Han Qingwen's room. Soon, Lin Xiaoyu wiped the sweat on his forehead, walked out of it with a smile, stood in front of Wang Kunjun, and stretched out his hand again: "Congratulations to the fifth brother, congratulations to the fifth brother, the fifth sister-in-law gave birth to a daughter for you." Now that the mother and daughter are safe, hurry up and send another red envelope. ”

Hearing that Han Qingwen's mother and daughter were safe, Wang Kunjun's heart completely relaxed, and he bowed to Lin Xiaoyu and said, "Thank you Eighteen Sisters for your help, this red envelope is definitely indispensable to you." ”

Lin Xiaoyu saw Wang Kunjun saluting him, and hurriedly flashed aside, and said, "Fifth brother is serious, this is what the little sister should do." took the fifth brother's two red envelopes back, and the fifth brother's little sister couldn't afford it. The fifth brother should hurry in to see the mother and daughter of the little fifth sister-in-law, and the little sister went to talk to the eldest fifth sister-in-law. ”

After Lin Xiaoyu's reminder, Wang Kunjun also came back to his senses, and didn't care about being polite to Lin Xiaoyu again, turned around and entered Han Qingwen's room.

The situation in Han Qingwen's room was similar to that of Zhang Xiaofei, the maidservant and the stable woman were packing up their things, and when they saw Wang Kunjun coming in, they all came over to salute and say hello. Wang Kunjun was also the same as just now, saying that he was happy and announced that everyone was rewarded.

If you want to say that this side is different from Zhang Xiaofei's side, it is that the baby girl is wrapped in the swaddling clothes next to Han Qingwen, and Han Qingwen herself is so tired that she is about to collapse, and she doesn't even have the strength to say hello when she sees Wang Kunjun coming in. Wang Kunjun walked to the side of the bed and squatted down, held Han Qingwen's hand in his palm, and said softly: "Let the lady suffer." ”

Han Qingwen shook her head when she heard this, and said, "It is a matter of course for a concubine to give birth to a child as an official, and it is not hard to say anything. It's a pity that I couldn't give the official a son this time. ”

Wang Kunjun naturally didn't care about men and women, and comforted: "Where does the lady come from, for a husband, giving birth to a boy and a girl is the same. Both men and women are the flesh and blood of their husbands, and their husbands will love them well. ”

Seeing that Han Qingwen still couldn't let go, Wang Kunjun comforted her for a while, and didn't leave until Han Qingwen fell asleep due to physical exhaustion.

Wang Kunjun got a pair of children, and everyone in the "Qingyuan" was overjoyed. "Jingyuan", "Liangyuan", and Feilongzhai also got the news, and everyone congratulated Wang Kunjun through the radio, and made an appointment that a month later, all the traversers would gather in "Qingyuan" to drink full moon wine.

Perhaps it is the good luck brought about by the birth of Wang Kunjun's two children, since mid-May, good news has been coming from all aspects of the team's work.

In late May, after several months of preparation, the salt drying plant named "Tanggu Salt Farm" by Zhang Weixin began trial production, according to Liu Wendong and Xie Tian, from the initial these days, the effect of drying salt is good, and the production of the first batch of salt is just around the corner.

Also in late May, the construction of the blast furnace and open hearth furnace in the "Cool Garden" was completed, and Yu Wende and his craftsmen began to ignite the trial after many days of preparation, and the first furnace of steel was smelted on the second day of the first month of June. Although the quality of the first furnace steel is not comparable to that produced by the modern steelmaking mills in the previous life, it can also meet the team's current demand for steel products. In the words of the members of the Mechanical and Weapons Sections, this kind of steel is already usable, but the service life and conditions of the various equipment and equipment produced from it are somewhat limited.

As steel began to be produced in a steady stream, the Weapons Section not only began to use steel to make new flintlock pistols, but also began to use steel to produce more advanced firearm parts according to the drawings provided by Li Junwu, Zhou Lei, and others. For example, in the previous life, it was very famous, the German Mauser 1898 7.92mm rotary bolt-pull rifle, the British Lee . Enfield 7.7 mm rotary bolt bolt rifle, Soviet M1944 (Mosin Nagant) 7.62 mm rifle, etc., all kinds of manual rifles that Li and Tuesday were able to draw detailed drawings - considering the quality of steel and ammunition consumption, for a certain period of time, repeating rifles such as machine guns were not on the research and development agenda of the weapons section. ,

In addition, at the suggestion of Li Junwu, the weapons department even cast a front-loading gun with a caliber of about 120 mm out of steel, which was used to make artillery from Shiyan's own steel.

In addition to the design and manufacture of various processing tools with these steels, the mechanical department also brainstormed and worked together to find a way, through the use of the Nanzhi River, which flows through the "Liangyuan", to drive the on-board generator on the modified armored repair vehicle, to achieve the power supply for the simple machine tool removed from the repair vehicle, and then with the scraper of modern high-hardness steel processing carried on the vehicle, successfully processed rifling for the barrel produced by the weapons section, and solved a major problem in the process of producing modern rifles in the weapons section.

However, due to the lack of necessary materials -- the pyrite from the Northern Han Dynasty has not yet been delivered -- Liu Wendong of the Chemical Engineering Section is a clever woman who has no rice to cook, and he cannot carry out the research and development of modern gunpowder at this stage, so except for the front-loading artillery, although the other weapon parts produced by the Weapons Section have been successfully assembled together, they cannot be carried out accordingly.

On the 26th day of the sixth month of the lunar calendar, the four members of the committee, members of the Ministry of Science and Technology, the Ministry of Security, the Ministry of Military Affairs and other departments, as well as the backbone of the Feilong Battalion squad leader and above, gathered in the "Cool Garden" to prepare for the upcoming artillery shiyan on the fortress battery.

At 10 o'clock in the morning, all the spectators went up to a makeshift wooden platform about 100 meters from the fort behind the fortress, within the outer defensive wall of the "Cool Garden", and waited to watch the first firing of the front-loading artillery. After the rangers who were in charge of cleaning the shooting range reported that everything was normal in the preset impact area and that no personnel were present, Li Junwu raised his hand to the two craftsmen guarding the artillery and asked them to load the artillery with gunpowder and projectiles. The two craftsmen followed the steps taught by Li Junwu in advance, and stuffed the lightest weight, one and a half catties of black gunpowder from the No. 1 medicine bag, into the barrel and compacted it, and then stuffed an iron ball that was used as a cannonball, and Zuihou stuffed it with a wooden stopper to prevent air leakage, so as to make full use of the energy of the gunpowder.

When everything was ready, the two craftsmen inserted the long lead into the fuse, lit the fuse, and then evacuated the battery where the gun was located as fast as they could, and ran into the gate of the "Cool Garden" to take shelter in case of an explosion. The length of the lead is very long, and the speed of combustion is not very fast, so there is a certain time interval between ignition and launch.

Although the interval between these days was actually only a few minutes, it seemed like a year for the people who participated in Shiyan's time-traveling group that day, especially the time-traveling members of the weapons section. Just as everyone began to worry about whether there was a problem with the lead, smoke and fire suddenly appeared from the muzzle of the artillery, and then a deafening loud noise reached the ears of the visitors, violently irritating their eardrums.

Except for the crossers, the other people involved in Shiyan were frightened by the loud noise, and a few older and less timid craftsmen were so frightened that they sat on the ground. Some craftsmen even thought that Shiyan had annoyed the gods, so they fell to their knees in fright, trembling like chaff, and kowtowed repeatedly in the direction of the artillery to save the gods and forgive their sins.

Although there was chaos up and down the platform, the traversers were not affected by the various reactions of their subordinates. After the smoke at the muzzle of the gun cleared, Li Junwu immediately raised the telescope in his hand to take a closer look, and when he saw that the gun was still lying firmly on the launch pad, he breathed a sigh of relief. Although it is not yet certain whether the barrel of the cannon is indeed intact and how far the shell has flown out, at least the explosion has not occurred.

Putting down the binoculars, Li Junwu was the first to climb down the high platform and walked towards the fort on the fortress, and the members of the weapons department, materials department, and chemical engineering department also followed him down the high platform and went with him to check the condition of the gun body. At the same time, a squad of Rangers rushed out and dispersed in front of the fortress, and began to search for the trace of the cannonball that had been fired.

It didn't take long for Li Junwu and the others to return to the high platform, and it could be seen from their expressions that they were very satisfied with the situation of the first shot. Li Junwu said to Wang Kunjun and others; "According to our inspection, the artillery is all intact, just wait for the rangers to get the shells back, and we can continue with Shiyan below." ,

The success of the first shot made everyone present very happy, and while congratulating Li Junwu and the others on the victory, they kept looking in the direction of the open space in front of the fortress, expecting the rangers to find the cannonball and calculate the flight distance of the cannonball.

About ten minutes later, a gunshot was heard in the distance in the clearing, which was the signal from the rangers after finding the cannonball. Judging from the strength of the gunfire, the flight distance of the shells was not close.

Soon, a ranger squad leader holding a small red flag in his hand galloped to the foot of the high platform and reported loudly: "Ladies and gentlemen, the projectile has been found, and the soldiers are putting the rope to measure, please go down to the high platform to test." ”

As soon as the crowd heard that the shells had been found, they hurriedly came down from the high platform and came to the fortress to wait. In a short time, two Rangers arrived one after the other. Each of them had a leather rope tied to the back of their horse's buttocks, on which were marked numbers representing distance. Li Junwu stepped forward, untied the leather rope from his horse, and dragged it to the bottom of the fort of the fortress, pulled it slightly, and saw that the leather rope was already taut, so he glanced at the number 917 on it. This shows that the nearly 10-kilogram pill fired with charge No. 1 flew out more than 900 meters away. Of course, these more than 900 meters include the distance of the projectile bouncing and rolling on the ground after it landed.

Later, Li Junwu checked the leather rope on the butt of another soldier's horse, and the number on it was 916. Although there is a slight difference in the measured data between the two leather ropes, an error of about one meter is still very normal. It was only then that Li Junwu officially announced that the first artillery firing was a success.

Amid another round of congratulations from the crowd, artillery firing continued Shiyan. After some pacification of his craftsmen, the craftsmen in charge of loading the ammunition finally mustered up the courage to walk up to the turret once more, and began to shiyan the second to fourth propellants in the back in the predetermined order.

After several launches, searches, and measurements, a group of data was counted. Shiyan showed that the No. 1 to No. 4 propellants (one and a half to three catties) were successfully fired, and the artillery did not explode or crack. The maximum range of the projectile ranged from 900 meters to 1,400 meters, which was basically in line with the previous expectations of the Ministry of Science and Technology, and Shiyan achieved complete success.

Through this shiyan, it was proved that the strength of the steel provided by the materials department can fully meet the requirements of artillery with black powder as the propellant. In this way, even if the development of new gunpowder in the chemical department does not go well, the weapons department still has the ability to supply the team with artillery.
