Pulling Pang and Liu, Kong Yuling smiled and said, "This one, called Liu Yuan, is a native of West Sichuan County, a doctor of mechanics in the United States, and the other is called Pang Yuyan, a native of Sichuan City, a medical student who studied in Japan, speaking of which, they are all your old folks."

Subsequently, Kong Yuling introduced someone Lu to Liu Yun and Pang Yuyan, "This is Uncle Lu, the owner of Minsheng Steamship Company, Mr. Lu Zuofu, a native of Hechuan, Chongqing."

Lu Zuofu, Liu Yun seemed to have some impressions, as if he had heard it somewhere, and he couldn't remember it for a while, but fortunately, under the influence of Lao Jiang and Kong Caishen, his face was already thick, and he naturally shouted in surprise, "Hello Mr. Lu, I have admired Your Excellency's name for a long time, and I am fortunate to see it today."

Pang Yuyan was a girl after all, and shouted softly, "Uncle Lu is good."

Mr. Lu glanced at someone with a smile, and then said with a smile to Pang Yuyan, "You are Pang Xuezhong's daughter, the last time I went to Shanghai, I heard Lao Pang talk about it, by the way, when you were just born, I also hugged you, why didn't Lao Pang accompany you today."

Pang Yuyan was a little stupid, how could Mr. Lu know her, she hugged herself when she was a child, why she never heard her father talk about it, and she was a little embarrassed to fiddle with the corners of her clothes.

At this time, Liu Yun finally remembered who Lu Zuofu was, he still knew from the "Yichang Defense Battle", in 1938, Wuhan was lost, the Japanese army entered Yichang, a large number of personnel and materials to move to Sichuan were collected in Yichang and could not be transported away, Lu Zuofu was the director of land and water operations of the Nanjing Military Commission.

After 40 days of hard work, Minsheng Steamship Company suffered heavy losses, but nearly 100,000 tons of military materials and stranded personnel were all rushed to Sichuan, making great contributions to the long-term war of resistance against Japanese aggression in the future, and was called the "Dunkirk Retreat of the East" by later generations.

Lu Zuofu is famous in China for engaging in the transportation industry, and was once called by great men, "one of the four people who will never be forgotten in the history of modern industry", and Zhang Zhidong who engaged in heavy industry, Zhang Jian who engaged in textile industry, and Fan Xudong who engaged in chemical industry, and were on a par with each other.

Liu Yun hurriedly straightened his attitude and shouted respectfully, "Good luck Lu Cichang."

Lu Zuofu was stunned for a moment, and couldn't help but look at Liu Yun carefully, and wondered a little in his heart, he also knew that he was about to be promoted to the deputy minister of transportation of the Nanjing government, how did this guy know, glanced at Kong Yuling, and suddenly realized.

Liu Yun also secretly complained at this time, he just remembered that in the defense of Yichang, everyone called Lu Zuofu as Deputy Chief Lu, so he took it for granted and shouted "Deputy Chief Lu", and only after blurting out did he remember that the time was wrong, as for 1934, whether he was the deputy chief or not, only God knows.

After all, Vice Chief Lu cultivated to his home, and smiled at Liu Yun, suddenly remembered something, and shouted, "You are Liu Ebei's son, Liu Yun."

"Ah", Liu Yun was a little embarrassed, it turned out that everyone was an acquaintance.

Kong Yuling said happily, "Uncle Lu, it turns out that you have known Yicheng for a long time."

Lu Zuofu was stunned for a moment, looked at Kong Yuling and Liu Yun quietly, for the relationship between the two, he had vaguely guessed a few points, and smiled bitterly in his heart, hoping that he had guessed wrong, and there was even more chagrin, he knew that he would not come to Yang Gefei Church, and now he doesn't care, no matter what.

Mr. Lu also regretted not being at the beginning, he had nothing to do to help Yin Changheng's granddaughter, Yin Qinlan pulled a red line, now it's okay, Yin Changheng is a celebrity in Sichuan, during the Xinhai Revolution, he captured and killed Zhao Erfeng, served as the governor of Sichuan, Yuan Shikai era, and also went to prison with Cai Yi.

The more Lu Zuofu thought about it, the more panicked he became, and hurriedly excused himself that he still had something to do, so he was ready to run away, and he didn't dare to ask Miss Kong about his private affairs.

Originally, before leaving, Lu Zuofu wanted to invite everyone to go to his Minsheng company to sit when they were free, but Miss Kong suddenly interjected, saying that her father, Kong Caishen, is now in Wuhan, do you want to invite everyone to sit together, but I didn't expect that Vice Chief Lu not only didn't talk, but ran faster.

Liu Yun and the two eldest ladies were speechless, and they couldn't understand the reason for it for a while, so they had to give up, the matter in front of them was still important, when they injected the wounded soldiers with special drugs again, they found that their complexion was much better, it may be that the new medicine came out, it was indeed extraordinary, in just a few days, it was seven or eight points, if it wasn't for the lack of arms and legs, it was basically no different from ordinary people.

Smith and Lu Liu, sleeping next to the wounded soldier's room, convenient for 24-hour observation, still do not give up, always want to find out someone's lies and flaws, in fact, the two of them have long believed seventy or eighty percent, but they are afraid that in case, when they think of 3 million silver dollars, they can't be careful.

According to Mama Mary's quiet report, it is said that Smith and Lu Liu have secretly recorded a lot of information, mainly the clinical effect of the new drug, including the injection time, injection method, the patient's detailed changes before and after the injection, and even the conversation with the patient.

After everything was done, Liu Yun and the others returned to Kong's villa, Kong Caishen had already gone out, Pang Yuyan had to continue to study sulfonamide tablets, Kong Yuling wanted to check the construction progress of the pharmaceutical factory, and Liu Yun didn't understand construction, so he was too lazy to go, so he just went back to the bedroom to sleep.

At night, when everyone arrived and drank tea together, Kong Yuling inadvertently said that when she saw Lu Zuofu during the day, Kong Caishen didn't care about it at first, but the more she listened to it, the more she felt that it was wrong.

After listening to it three times before giving up, Minister Kong knocked lightly, thought for a long time, and suddenly thought of a possibility, glared at someone fiercely, snorted coldly, and walked away, making everyone stunned, especially Liu Yun, who felt that he was more wronged than Dou E.

Three days passed quickly, and Liu Yun also wondered about one thing in the past few days, Kawashima Yuqin, the dead eunuch, I don't know why, but he was nowhere to be seen, and he waited so much that the flowers were grateful.

It was also time for Liu Yun to go to the Hanyang Arsenal to inspect the progress, just along with Pang Taishi, who was very busy these days, not only helping Kong Yuling take care of the progress of the pharmaceutical factory, but also proposing various improvements to the design and planning of the factory.

According to Taishi himself, the father and daughter should be worthy of 15% of the shares, and according to Liu Yun's observation, the gang sometimes has to plan transportation plans and work out the details of steelmaking equipment entering Sichuan.

In addition, according to the report of Zhibrain, the ant robots in the slag yard have basically risen to level 39.9, and the performance has been significantly improved, with a total length of 45cm, a width of 18cm, a height of 18cm, a total weight of 10.9Kg, a double jaw bite force of 18.59 tons, an economic moving speed of 4.0-12.5m/s, a mining/processing of 218.7g/s, a combined drive of solar energy-chemical energy, an effective activity radius of 14.4-23.4 kilometers, and a mining of 18.89 tons/day.

Liu Yun suddenly remembered something, he still had six ants that had not been upgraded, five of them were made of iron vests, and one was used as a penicillin purifier, and it was good to say that the purifier was a bit troublesome, so he simply waited until Miss Kong went out, and then quietly took away the medicine king Shending, and even thought of a good excuse, in order to increase the production of penicillin, he specially went to the arsenal to remelt it.

After arriving at the Hanyang Arsenal, in addition to reporting to the office of the director of the Qin factory, they inspected them one by one, and the first thing to inspect was the artillery research and development team.

Liu Yun also didn't expect that in the artillery laboratory, he not only met Li Hans and Hu Youbing, the pair of artillery partners, but also unexpectedly met the members of the chassis team, automotive expert Zhang Sili, and mechanical expert von Schnodder.

Take the tank gun as an example, the caliber is easy to do below 75 mm, the technology has matured, the smoothbore or rifle can be changed at will, but when it comes to 88 mm and 105 mm, there will be problems, and in several tests, it has been found that a little, sometimes a little correction, will lead to a huge deviation.

Rifled guns and recoilless guns, both have their own advantages, in the case of the same caliber, the muzzle velocity of the exit of rifled shells is much higher, which can penetrate the enemy's armor and pillboxes to the greatest extent, but there is a little bit of a bad thing, it is troublesome to load, the rate of fire is slow, and the recoil is much greater, which in turn, affects the accuracy, of course, the situation of smoothbore guns is the opposite.

Therefore, Hans and Hu Youbing believe that the best way to solve the contradiction between the above two is to either increase the bore pressure of the artillery fire or increase the caliber of the artillery fire, but in the final analysis, it is necessary to solve the material problem of the artillery fire, so the help of material experts is needed.

However, at the same time, the research and development of the chassis, also encountered similar problems, there are a number of advantages and disadvantages, difficult to choose the contradiction, in the process of mutual discussion and learning, the two groups naturally mixed together, the main contradiction at present, is focused on the material problem.

The ants of the slag yard have accumulated a large number of new alloys and various performance indexes while upgrading themselves, which can fully meet the needs of the artillery fire team and the chassis team.

This guy is also advanced now, and he doesn't explain the reason at all, but he vaguely says that he can solve part of the material problem, and new materials will be sent soon.

On the way to the slag yard, Liu Yun went to the "Sino-German Cooperation Institute" again, ready to check the production of parts and see the difficulty of producing the new engine, but before he could speak, Da Lite and the Ouyang brothers apologized tremblingly, their parts production is currently very bad.

It turned out that the previous new alloys, all made by them into a variety of processing tools, originally wanted to go to the slag yard to find some new materials, but did not expect to find all the garbage, in the end there was no way, had to use high-quality imported steel instead, to get out of the current large number of engine parts, comprehensive performance without asking to know, most of them have dropped a few grades.

According to the test data, these parts can still be used, but once put into use, the 800 horsepower of the new engine will be reduced to 720 horsepower, and the service life will be greatly reduced, the preliminary estimate is that the overhaul time is 600 hours.

Fortunately, Liu Yun was not too disappointed, did not fall out of 700 horsepower and 500 hours, think about the 21st century, the service life of many aero engines is only 500 hours, as for the tank engine during World War II, it is not accurate, often the theoretical design data is 1000 hours, and when it is actually used, it has to lie down for about 200 hours.

"Sharpen the knife and don't cut wood", or not, and make more new alloys, Liu Yun can emphasize this time that once the new material arrives, no matter what, a set of new material engine parts must be made, anyway, in three or four days, a prototype will be assembled, and the rest will not be cared for, let Dai Lei and others look at it, if there are still problems, you can change people to do it.

Under the escort of the guards of the arsenal, more than a dozen workers transporting materials came to the slag yard, and Liu Yun, in order to prevent others from discovering the abnormality, asked others to wait in the mine, and he personally carried them up one by one, and then the workers carried them away, and according to the pre-arranged share arrangement, they were distributed to the "Sino-German Cooperation Institute", as well as the artillery team and the chassis team.
