November 15, 1940, Qijiang County, Qijiang Garrison Headquarters

The underground of the garrison headquarters has long been hollowed out by Wang Yue using the system space, and then supported by large steel-concrete cement components in this time and space, and a miracle underground building complex has been created here in Qijiang, and it is not limited to Qijiang County, but is connected by huge cement pipelines and underground caverns everywhere outside the city, including the basic material hoarding place in Wang Yue's hand, which is covered in this building complex.

Originally, Wang Yue did not plan to open all the underground space to Li Yunlong and them so early, but the battle of the dyeing workshop also gave Wang Yue a wake-up call, the provisional 68th Division is now too dazzling, if the battle of the dyeing workshop is encountered by Yamamoto's troops, I am afraid that the provisional 68th Division will be injured, in order to avoid this situation, in addition to continuing to strengthen the control of Qijiang County, it is to transfer a large number of facilities and equipment to the underground, and at the same time establish a complete access process and defense plan.

As Colonel Rudolph, who came to the provisional 68th Division for the first time, he never dreamed that Zhao Gang would take him to this underground laboratory, in other words, I am an outsider, Hans and Japan are still allies, is it a bit too much for you to trust me like this? But then again, how did you manage to build such a large underground laboratory in Qijiang County in just a few months, which is bigger than all the large underground facilities near Albis Mountain, but how is it possible?

At this time, Zhao Gang and Rudolph were looking intently at the back of the large glass in front of them, several white coats were tossing there, at first it was a large bucket of castor beans, after weighing, these castor beans were placed in a huge wok-frying oven to fry and dry, then crushed, then added extractant, high-speed stirring, standing, separation, and finally, the separated castor oil was weighed.

"61 kilograms? Oh God, 100 kilograms of castor beans actually produced 61 kilograms of castor oil! Rudolph saw the latest figures, he felt that his whole person was not good, during this time he also investigated the information related to castor oil in Hans, in Hans, the best castor variety, castor seed oil yield is only 30%-40%, just like that, the seeds of related varieties are also strictly controlled by the Air Force, no way, for advanced fighters, the use of castor oil as lubricant can improve the performance of fighters to a certain extent.

This time, even if you can't get the technology of biodiesel, just getting this castor seed is a huge harvest, with this thing, Mr. Air Marshal can use better lubricant for all fighters, and generally improve the performance of fighters, this temptation is too great, as for whether the Chinese people will do tricks and feet in the extraction process, Colonel Rudolph is not worried at all, if you want to buy it in the future, you must verify it yourself, don't have to be so troublesome, only a few castor beans, it's okay.

"Because of the process, there is a lot of toluene here, but it doesn't matter, it won't affect the quality of the oil." Zhao Gang mentioned it on the side, Wang Yue told him that this technology can be used to produce edible oil, Zhao Gang scoffed at this, what is toluene? It is used to process edible oil, even if there is only a little residue, it is a serious crime, right?

"Well, it doesn't matter, in fact, the same technology is also used in our country, as long as it is not used to process edible oil, there is no problem, after all, toluene is the most efficient." Rudolph nodded, but his mouth didn't care, although the technology seemed to be the same, but he suspected that the extractant used by the Huaxia people was probably not a single-ingredient toluene, it was really this efficiency, much faster than the relevant process he knew.

"The next step is to do the transformation experiment, because the equipment has to be warmed up, so we need to wait a while." Zhao Gang took Rudolph to the other side of the glass, where there are a lot of stainless steel tanks, reactors, pressure vessels, conversion vessels, separation vessels, filtration vessels, all here, unlike the previous laboratory, many instruments here are not facing the glass.

To put it bluntly, in addition to the catalyst, this process is the control of pressure and temperature, if the quality of Rudolph is high enough, he can definitely deduce the information of the entire process flow according to a small amount of information, so he has to be prevented.

"That's General Li Yunlong?" Rudolph asked with some surprise, he naturally didn't know Li Yunlong, he didn't understand how Li Yunlong could appear here.

"Yes, General Li Yunlong, as the inventor and owner of this technology, it is very appropriate for him to demonstrate it to you." Zhao Gang's face did not change and his heart did not beat to explain, originally, Wang Yue asked him to do this, but Lao Zhao really couldn't get over the hurdle in his heart, so it finally fell on Li Yunlong, anyway, Li Yunlong had "published" a lot of technical articles before, and it was not so incomprehensible to invent a new technology.

"It's incredible, General Li Yunlong is really amazing." Rudolph complimented his mouth, but the corners of his mouth were twitching, as an intelligence officer, he naturally investigated Li Yunlong's life, but he would not believe that Li Yunlong was a scientist because of a few technical articles.

"Mr. Colonel, have you seen "Eight Hundred"?" Zhao Gang suddenly changed the topic, Rudolph must have watched "Eight Hundred", and according to the information provided by the Military Administration, Hans also secretly remade some films, it seems that they want to study the filming technology of the film.

"I've seen it, it's just amazing, even the one in the Prime Minister's Office praised the film, but it's a pity that I can't get a copy of the original." Although Rudolph was puzzled, he naturally agreed.

"That film is also the work of General Li Yunlong, if it can expand the influence of the film, I believe it will also allow General Li Yunlong to improve his impression of your country, after all, this matter of technology output still needs the approval of the technology owner in the end." Zhao Gang held back a smile.

As a "supervisor", he knows that Li Yunlong has "created" a lot of films, and as part of Wang Yue's overall plan, he believes that these films will be released one after another to boost people's morale and expand their influence, in Wang Yue's words, this is also part of the cultural invasion plan.

Over the years, the country has been deeply influenced by Western culture, and it has reached a critical juncture, Chinese characters have almost been replaced by English, the Spring Festival has even been canceled for a time, some literati are still planning to ban traditional Chinese medicine, everything is running towards the road of total westernization, if it is not for the outbreak of war, I am afraid that these people will continue to bark wildly, and finally continue to lose teachers in the cultural field.

Some people died, but not completely......
