Lin Youde basically didn't listen to the next class on this day - in fact, he didn't understand it, his knowledge of science and engineering was almost returned to the teacher, and he flew at a low altitude in high mathematics when he was in college, so even the science and engineering courses in 1930 were in the clouds. Not to mention the unheard of magic trick courses.

However, Lin Youde did not gain nothing completely, and the course called "The History of the Development of Magic Techniques" that afternoon benefited Lin Youde a lot. Interestingly, most of the students in this course were sleeping, and they immediately set off Lin Youde, who was engrossed in listening to the lecture and asking questions, to be extremely scholarly, and moved the old man who lectured to finish, and invited Lin Youde to drink coffee after class.

Lin Youde thought about it for a while and felt that this was a good opportunity to go, and as a result, he got quite a lot of information about the development of magic guidance techniques from the old man.

It turned out that the West was able to develop modern magic techniques in a short period of time, and achieved an advantage enough to suppress the time-honored mechanical techniques of the East, mainly because they "violated the taboo of the gods". Around the 17th century, a group of Western scholars risked the death of a dead goddess to be dissected, risking the death penalty of the prison.

Later, a mad scientist named Frankenstein used his status as a court lecturer to kidnap several gods and perform vivisections with the help of anesthetics. The most popular scientist was burned at the stake, but the results of his research were preserved and became the cornerstone of his magic technique.

It is said that some extreme scientific organizations regard Frankenstein as "Prometheus the Fire Stealer".

In addition to these, Lin Youde also figured out the distribution of the bloodline of the gods in the world today with the help of the old man - Lin Youde found that he had a huge misunderstanding before, he thought that the bloodline of the gods was distributed according to race, for example, the Celts had the bloodline of Celtic mythological characters, and the Norsemen had the bloodline of the Aesir gods, but in fact, the distribution of this bloodline came according to the region.

Taking the United States as an example, from the beginning of the founding of the country, they have gone all out to "poach" from other countries in the world to attract immigrants from other countries, but they have not been able to increase the "production" of pure-blooded gods and women with the blood of gods and queens among the people, and they are forced to desperately develop conventional industry - the impact of magic guidance techniques on the economic field is far less than that of the military field, and the Americans obviously hope to rely on strong conventional industry and economic strength to make up for their natural shortcomings in magic guidance techniques.

In addition, the situation in the United States is much stronger now than it was at the beginning, the United States originally only had thirteen eastern states, and there was no bloodline of fart gods, so that the British concluded that when the British gods who were soaked away by Washington died, the British Empire would be able to recover the North American colonies without blood. But I didn't expect that the Americans relied on Washington's wives to conquer westward and control a large area of Indian territory, and finally began to produce the god sisters of the Indian system.

Similarly, the purpose of the Mexican-American War in this world was not gold mines, nor vast corn-producing fields, but the territory of the former Aztec Empire, which Mexico controlled.

In addition, the United States seized Easter Island while the Europeans were dealing with Napoleon, and launched a huge colonial project that has been carried out intermittently to this day.

Incidentally, the Americans seem to have made the wrong bet, Easter Island has now been filled into a huge island with a million people on it, but not a single long-eared goddess has yet been born.

That's right, long ears, long ears like those boulder statues.

This is the third useful piece of information that Lin Youde got from the old man: many pure-blood gods have physical characteristics that can be seen at a glance as "origin". Ancient Germanic goddesses generally have typical Germanic characteristics, with English goddesses often having black hair said to have been inherited from Queen Arthur, and Greek peninsulars often have large paws, which are generally weak points.

This is not the most exaggerated, Lin Youde saw the portrait of a pure-blooded goddess in Denmark in modern times from the professor, and she was actually a human fish.

What makes Lin Youde even more speechless is Norway, which has not had a recorded pure-blood god so far, but whenever Norway's territory is violated, the "shining star-like" little things will fly out of the forest in droves to fight the invaders, and they will disappear without a trace immediately after the invaders retreat.

Of course, the combat effectiveness of these small things is not particularly high, so there have been several times in history when countries or nations with unprecedentedly powerful gods have conquered Norway, and the conquerors will generally send a large number of search teams into the forest, and even try to force these small things out by setting fire to the mountains, but to no avail.

However, in the last hundred years, with the popularization of magic weapons, the guardians of Norway have become more and more weak, Denmark, Sweden, and even Germany have landed on the shores of Norway and defeated these small guardians.

Coming out of the old man's office, Lin Youde had mixed feelings in his heart, and he lowered his head and silently digested the knowledge he had just obtained.

While digesting, Lin Youde recalled the incident with the group of Yingzhou people in the morning, and in his memory, the group of Yingzhou people did not wear hats, except for the guy who called himself Matsudaira Qianhao. Combined with the new posture (knowledge) he received from the old man, Lin Youde began to suspect that the hat was meant to hide some features on his body.

Like, fox ears or something.

Lin Youde was thinking about it, when he was suddenly startled by the shrill horn, he suddenly came back to his senses, dodged the car that was already close at hand, and then found that he had returned to the door of the mansion.

Then he remembered that before he went to the professor's place for coffee, he made an appointment with the friend who still didn't know the name of Lu Dao to go to the recruitment office to inquire about the work-study program.

Lin Youde hesitated in front of the door for three seconds, deciding to pretend to forget about it, anyway, he is now a diner of the landlord Miss Viola, and he doesn't need to think about work-study. He pushed open the door and went up the dim staircase to the second floor, Viola's gorgeous long golden hair appeared on the third floor, the girl held on to the guardrail of the staircase, stretched her neck to look down, and said very unhappily when she saw that it was Lin Youde: "You came back too late." ”

"I talked a little bit about life and ideals with the old professor."

"You also think about how I feel when someone comes upstairs to see me."

Lin Youde raised his hands to make a surrender form, and asked while climbing to the third floor: "Although you are anxious, Miss, I still want to eat something first." ”

"I'm having dinner, come in and eat together."

With that, Viola's head disappeared from the railing.

Lin Youde quickened his pace and went up to the third floor, and sure enough, he saw Viola's door open, wafting out of it - well, the smell could smell food, but it wasn't really fragrant.

When he entered Viola's room, the food on the coffee table was so poor that Lin Youde wanted to cry, yesterday when he saw Viola calling for supper, he thought it was because it was too late to prepare, and when he saw the black bread taken out by his friend this morning, he felt that it must be because the two of them were poor and had a low social status, and now it seems that the German people are indeed hundreds of years behind my big foodie empire in terms of eating.

In this way, it seems that the "cooking skills" that Lin Youde practiced by making instant noodles in the dormitory have the hope of fooling the Germans.

Maybe you should try it tomorrow.

Lin Youde thought as he broke off a piece of bread and took a bite - fortunately, it tasted much better than the dry and hard black bread in the morning.

At this time, Viola, who was buttering the slices of bread in her hand, said, "Well, we talked about ...... last night."

"Wait a minute!" Lin Youde interrupted Viola's words and asked her solemnly, "Do you have the Reichsmark in your hand?" ”

"Of course," Viola said, with a puzzled expression, "but I won't give you any extra marks other than wages." ”

"I don't want you to give it to me." Lin Youde waved his hand and continued to ask, "Can these Imperial Marks be exchanged for gold?" ”

In Lin Youde's original world, Germany canceled the gold standard during World War I, and the original "gold mark" became a "paper mark", but the world here may be different. If the World Realm Mark here is still on the gold standard, then what Lin Youde has to do next will be much simpler.

Viola nodded, but she still looked like she didn't know why.

Lin Youde continued: "Tomorrow, when the bank starts to open, immediately exchange all these marks for gold, and then withdraw them and store them in this reliable place." ”

"For what?" Viola frowned, her buttered hand had completely stopped, "I won't do it if you don't explain it clearly." ”

"I was about to explain to you." Lin Youde also took a slice of bread and began to spread butter, "Under the influence of the United States, the economic situation will soon become more severe, the mark will depreciate significantly, if William III and his minister of economy are not pigs, it will be forbidden to exchange the mark for gold, and the gold currently stored in the bank vault will be sealed by the state violence agency." ”

"This ...... The Imperial Government has already taken steps to save the economy, and the newspapers say that the economy will improve in the next six months......"

"If you can believe what the newspapers say, you don't have to hire me." Lin Youde leaned forward slightly, and said to Viola seriously, "The president across the sea has failed to understand the essence of this economic crisis, and the policies he has implemented will fail in the face of the economic avalanche." The essence of this crisis is that there is overproduction in the United States, and the consumption power of the people is far less than the amount of goods provided by the factories, so the economic bubble that has been piled up with futures and stocks will disappear in an instant. The stock crash has already collapsed, the futures crash continues, and then the crisis will affect the banking sector, and the banks in the bubble era will lend unbridled to the capitalists, and now all these loans will become bad debts, and the banks will suddenly find that they have so little cash that they have no way to turn around. People who need to withdraw their savings to survive in the face of the crisis will soon find that the banks have no way to respond to their requests for withdrawals, and then panic will spread, and people who have no need to withdraw money will flock to the banks to demand that the banks hand over their deposits, and the banking industry will collapse in an instant. ”

"The banks collapsed, how is this possible...... However, there is no logical loophole in your words, and I can't find ......"

"Of course you can't find it," Lin Youde maintained a rather aggressive stance, "because this is the truth, the United States is already more than halfway down this road, and Germany is just leaving the starting point, but every day is closer to the end." ”

Viola was silent for a moment before asking, "So, isn't there a way to stop this from happening?" ”

"No," Lin Youde shook his head, "there is only one way to shorten the length of the Great Depression and mitigate the damage it causes." But once this big trend starts, it will roll forward and will not stop until the end. ”

Viola's expression looked very sad, she put down the buttered table knife in her hand, pondered for a moment, and then said to Lin Youde: "I want to write a report and submit it to the relevant departments of the empire. ”

"Yes, but will it work?"

"I guess I'll laugh at it. But when things do get to the point where you say, we can turn this report out, and this kind of unpredictable prophet can at least increase our influence, right? ”

"Makes sense." Lin Youde nodded.

"So," Viola said heavily, "so it's better that these things you say are going to happen, or I won't have fun with you." ”

"Remember to exchange Mark for gold." Lin Youde responded disapprehantly.

Viola snorted, picked up the knife again, and while continuing the buttering work that had just been interrupted, she asked Lin Youde: "Now tell me, how can you reduce the duration of the depression?" ”

"It's very simple, there are three main points."

In the following time, Lin Youde began to explain to Viola in detail the Roosevelt's New Deal in the original world.
