"Anyway, although we didn't get a complete set of manufacturing machinery, we still got medium carbon steel, and with this steel, we can still get relatively good shells, at least much stronger than before!" Su Huizhen said. "Well, it's not like it's empty-handed in general!" Liu Hai sighed and said, "When I was in Germany, I saw the strength of Germany, its machinery and equipment processing is fine, the industrial facilities are complete, and all kinds of talents are comprehensive, and the German Empire is well-deserved, so a big country can turn the whole Europe upside down, although it failed, but it is enough to witness its strength, when will our motherland be like Germany, dominate the world!" "A country always has its trough and fragile times, but the German nation, like the Chinese nation, and our Russian nation, are all great nations, and such a strong nation, no matter how backward and low it is, is very strong once it rises, especially a country like China and Russia, it is only a matter of time before it becomes strong!" Su Huizhen said. "I hope that my country can rise up one day and become a strong country, unlike now, even a small cannon has to be controlled by others!" Liu Hai said unwillingly.

After more than two months of study, the people brought by Liu Hai have basically mastered the smelting course of high-strength steel, especially the production method of medium carbon steel obtained by Liu Hai from Otrov, which is not in vain! On the way back to the Northeast, Su Huizhen was tired of Liu Hai again, on the thousand-mile railway line, Su Huizhen never left Liu Hai, Su Huizhen's charm and figure made Liu Hai restless. After returning to the Northeast, Liu Hai and Su Huizhen immediately rushed to the ironmaking plant and arranged the workers to work, while Liu Hai himself and a group of technicians began to develop medium carbon alloys! I have to say that Otrov is very interesting, not only gave the production process, but also wrote his own experience and opinions on it, which is easy to understand and very clear! After more than a month of hard work, Liu Hai and others finally made a high-quality medium carbon alloy! After a series of cuts and molding, the installation of the charge, a heavy shell was made, and Bang Hai decided to test the gun himself!

"Are you sure?" A leader who participated in the experiment asked, this leader is the big leader in charge of the logistics and military industry department, and this time he came here to make overall arrangements and assist Liu Hai in the manufacture and experiment of new artillery shells! "I don't know, the first experiment, success or failure are possible, and the certainty is not very large!" Bangs tell the truth. "It's okay, take your time, we'll make it!" The leader patted Bangs on the shoulder. "Hmmm! Here we go! Bangs waved his hand, and several people connected the lead and pressed the switch of *! There was a huge explosion, the ground was shaking, a puff of black smoke rose in the distance, and the cannonballs exploded! "This is the shell power of the Americans' 155-mm heavy * guns!" Bangs said. "Yes, yes, it's true that the old beauty is not blown out!" The leader said, looking at the exploding shell. "Next is ours!" Bangs waved his hand, and another cannonball exploded, the same sound was huge, the same power was huge! "Oh!" There was jubilation on the test ground, and bangs also let out a sigh of relief! "Great, Comrade Chief Instructor, no worse than the Americans, great, great! I'll report it to Chief One! The leader also said excitedly.

"Sea!" Sima Hong hugged the bangs who returned to the artillery school tightly, and they hadn't seen each other for a few months, and both of them were very happy! "My mission is complete, I'm back, I miss you!" Liu Hai hugged Sima Hong and said warmly. "Well, I miss you too!" Sima Hong also said excitedly. "Chief Instructor Liu!" , just as the bangs were about to stick their lips up, there was a loud scream, which separated the two people like an electric shock! "What's the matter?" What Liu Hai saw was an officer of an artillery school! "Chief Instructor Liu, the principal told you to go!" The officer looked at the unnatural bangs and Sima Hong, and naturally what he had done, and said with some nervousness. "Okay, I got it!" After Liu Hai finished answering, the officer hurriedly left! "Honey!" Liu Hai was a little embarrassed and hugged Sima Hong: "There is a saying that good things are grinding, right?" "Hehe, go ahead, see what the headmaster is looking for you!" Sima Hong said. "Okay!" Liu Hai shook Sima Hong's hand again, and then went to Principal Zhu's office!

"What's the matter with Principal Zhu?" Bangs asked directly after entering. "Oh, that's right, didn't our new artillery shells succeed in trial production? The first batch has been equipped with troops, but the actual attack effect still needs to be tested in actual combat, the superior means that a professional needs to be sent to follow the artillery to observe the battlefield and collect some usage data, this task is too professional, a lot of data only people in the industry understand, so you have to be! Principal Zhu said. Yes, a newly made weapon needs to collect data on its battlefield effects, and this thing can only be me! Liu Hai understands the specialization of this matter, in addition to himself, there are only a few Japanese engineers in the arsenal, but now after the successful trial production of artillery shells, all positions are overloaded, and they can't leave! Although it is said that it is only himself, Liu Hai is reluctant to go to the battlefield, no matter what, no one will feel good when he sees his former comrades-in-arms killed and injured everywhere! "Don't you want to go?" Principal Zhu looked at the bangs with an unnatural expression and asked. "To be honest, I really don't want to go, I just came here to be an instructor to avoid this war, and if I go to the battlefield now, I don't want to go!" Bangs tell the truth. "Hehe, the first leader means to ask for your consent, if you don't want to, then send someone else, since you have this attitude, send someone else!" Principal Zhu said. "Who are you sending?" For this matter, Liu Hai really can't think of anyone else! "Me!" Principal Zhu pointed at himself, "You think it's just you, my old Zhu doesn't eat rice!" Hehehe! "Hahaha, I forgot, you are also an artillery talent!" Liu Hai looked at Principal Zhu happily!

Principal Zhu told Liu Hai that this time it was not only to observe and collect data, but also to participate in the battle commanded by artillery, in fact, the above meant that he wanted Principal Zhu to mobilize Liu Hai to participate in the command battle, but Principal Zhu, who knew Liu Hai very well, was not very willing to let Liu Hai do what he was unwilling to do, so he told his superiors that he would definitely mobilize Liu Hai, and if the mobilization failed, he would personally go up to command! Now Principal Zhu has gone through the motions and chose to go to the battlefield to command the artillery battle! The reason why one person was to be selected from between Liu Hai and Zhu Rui to go to the front line to command the battle was because it was a large-scale battle! The People's Liberation Army's Northeast Field Army has taken control of 97 percent of the land and 86 percent of the population in Northeast China, thanks to the results of successfully carrying out mass work and building local grassroots organizations! The Kuomintang army had four corps, 14 corps, 44 divisions (brigades), and a total of about 550,000 local security teams, but they were divided and compressed into three disconnected areas: Shenyang, Changchun, and Jinzhou. Due to the control of part of the Bac Ninh Railway by the People's Liberation Army, the land transportation from Changchun and Shenyang to Shanhaiguan was cut off, and supplies were all airborne, and material supplies were scarce. The Central Committee of the Communist Party of China held an enlarged meeting of the Politburo in Xibaipo, and decided to seize the favorable opportunity to engage in a strategic decisive battle with the Kuomintang, and the direction of the decisive battle should first be directed to the northeast, where the situation was favorable to itself. At this time, the Northeast was the only area in the country where the People's Liberation Army exceeded the Kuomintang army, was the most developed area of China's heavy industry and the largest grain-producing area, and was also the first area occupied by the Japanese army invading China.

But what Liu Hai never expected was that Zhu Rui went to the battlefield instead of himself this time, not only to complete the task on his behalf, but also to die on his behalf! The Liaoshen Campaign began, and the main force of the Northeast Field Army quickly rushed to the Beining Line. Zhu Rui commanded the artillery column to participate in the battle to conquer the county seat of Yixian, a fortified stronghold of the Kuomintang army north of Jinzhou. The Chinese People's Liberation Army launched a general attack, Zhu Rui ordered, artillery of various calibers opened fire, and in less than six hours, destroyed the fortifications operated by the Kuomintang government for many years, completely annihilated the Kuomintang government army, captured the division commander Wang Shigao alive, and victoriously opened the prelude to the Liaoshen Campaign! In the battle to capture Yixian, the Chinese People's Liberation Army used captured American guns for the first time. In order to understand the performance of this artillery, before the battle was over, Zhu Duan came out of the command post, unfortunately hit a mine on the way, and died heroically at the age of 43. After hearing the news of Principal Zhu Rui's heroic sacrifice, Liu Hai personally went to pick up Principal Zhu's body and bury it!

After that, Liu Hai found the No. 1 leader with a sense of guilt, saying that he was willing to take over the command position of Principal Zhu Rui and complete the task he did not complete, but what he didn't expect was that he was refused! The No. 1 leader told Liu Hai that President Zhu understands the importance of the matter, and you are a talent in all aspects of artillery and troop organization and even artillery manufacturing, so you can replace Liu Hai to command the battle on the battlefield, and he knows that you are unwilling to go to the battlefield, so for the development of artillery in the future, you will replace Liu Hai on the battlefield. If Liu Hai is sent to the battlefield now, it will be to live up to Principal Zhu's hard work, so the No. 1 leader will send someone else to command, and Liu Hai will continue to stay in the artillery school.
