Comrade, Your Ingredients Are Too Complicated

There is no doubt that Huang He is a time traveler. In his previous life, he was a Ph.D. in applied mathematics and aerodynamics. Before time travel, he and several friends were being interviewed by a certain UP owner of Xiaopo Station.

Everyone is discussing a game called Stars, and they are seriously having fun analyzing the feasibility of many technologies in the game in the future, but their remarks have attracted the attention of some special observers.

Huang He and his friends were captured. In the days that followed, several people saw the alien's activity log about that day.

"After a period of observation, we discovered several very talented scientists among the indigenous people of this planet. They tried to use backward theories to explain advanced technology."

"These people are not valued. We can plunder them back to their home planet and brainwash them to become our scientists. If we do not intervene and let them continue to stay in the indigenous civilization, it will only be a waste of their talents."

"Capture him and serve us in the future."

"This is an ordinary matter, a daily record."

Due to their contempt for lower civilizations, the aliens who captured them did not keep them under close guard at the first time. After secretly observing for a period of time, they carried out a long-planned self-rescue.

Fortunately, they succeeded. Not only did everyone escape the alien spacecraft, they also returned to Earth.

Unfortunately, during the escape process, they were not only forced to separate, but also returned to the wrong time and entered strange bodies.

On the first day after crossing, Huang He worked hard to sort out the strange memories in his mind. He found that he had arrived at a time during World War II.

In this dangerous world, he is a native of the Dabie Mountains. When sorting out interpersonal relationships, he saw two characters in his memory that surprised him.

Zhang Wanhe! Li Yunlong!

But after escaping, he quickly accepted this fact. After all, there would be nothing worse than being brainwashed and transformed by aliens. And no matter what, this is his homeland.

So he combined the memories of his predecessor to formulate a careful plan for himself.

First of all, he used some simple methods from later generations to improve the production efficiency of fellow villagers in several nearby villages. He was recognized by the villagers and became a capable person in everyone's mouth.

After revealing his desire to go to school, several village elders chipped in for his travel expenses to the big city and his first year's tuition.

Huanghe even obtained a letter of introduction from a local administrator and a letter of recommendation from the middle school principal.

In 1927, he came to National Chiao Tung University with a letter of recommendation, a 4-inch bust photo and a letter of introduction.

After passing the written examination with perfect scores in almost all subjects, he successfully passed the interview and physical examination, and successfully left the mountain to study in the Department of Mechanical Engineering.

With his excellent learning ability and social skills, Huang He became a famous figure in school, and the principal even exempted him from tuition fees. When he officially graduated four years later in 1931, on the recommendation of the school's senior officials, he went to the Never Surrender Polytechnic in Zhengbai Banner.

In 1937, he became the first outstanding graduate of the college to have the title of "Engineer Graduated from the Polytechnic Institute". In the same year, he entered the Second Special Design Bureau of the northern country on the recommendation of many mentors.

Since the outbreak of the Anti-Japanese War, Huanghe has been actively active in Europe, raising various equipment and weapons for the motherland on behalf of overseas compatriots.

After being invited by Zhang Wanhe from his hometown in 1939, he relied on the connections he had accumulated over the years and paid a heavy price to escape. He returned to the motherland without hesitation and prepared to join the Anti-Japanese War.

Like most traversers, the Yellow River has a system. Although he didn't know the origin of this system, after experiencing so many incredible things, he had long since settled down.

This system remained silent until August 14, 1939, with only the progress bar that jumped from time to time to show its existence.

Today the system is finally officially launched! He immediately focused his attention, and the system interface appeared in his mind.

As an experienced player, Huang He found that this system was actually very similar to a certain 7+ coloring game in his previous life. However, after careful exploration, he keenly discovered many differences. Perhaps this was just the system finding a template that was easier for him to understand.

Fortunately most of my old friends are here.

Just like a decision-making system, by selecting and completing various decisions in the system, certain gains can be obtained or certain negative effects can be eliminated. Within a unit time period, only one slot can be used.

According to the system prompts, a decision was about to be completed without any action on his part.

"Establishing the Academy of Sciences:

We will integrate various research institutions and universities and form them into new institutions to improve management efficiency.

Effect: Get a research slot

Obtain five researchers in designated fields every month

Current progress: 38/70 days"

Although the system did not explain it, Huang He quickly understood that certain decisions could be passively unlocked based on what he had done, and it did not occupy a position within the unit time.

For example, the one being unlocked must be because the Yellow River has a certain reputation in the research field. In the Second Special Design Bureau, he even participated in the research of Katyusha's predecessor.

If it weren't for the help of many mentors and friends, he would never be able to return home now. As we all know, science has no borders, but scientists do.

Huang He twisted his body away from Makarov. The system was his secret, and he wanted to avoid being discovered by others as much as possible.

Then he frowned and asked the most crucial question.

"System, I need your help. Countries now have strict controls on foreign scientists. As far as I know, many powerful people are studying or researching abroad. The researchers you just mentioned, how did they come to me? ah?"

The system is very humane and provides answers without any hesitation.

"The host doesn't need to worry. Everything you get through the decision tree or scientific research slot, this system will create reasonable reasons and ways."

"For example, materials can be picked up from the warehouse of the Logistics Department. Everyone except you will assume that you obtained these materials through your own connections, and they will be transported to the base by air or land."

"I have to praise the host for laying the groundwork before this system is activated!"

Huang He still didn't understand when he heard this:

"What about the research results obtained through the scientific research slot? Even if I have certain achievements in the research field, I am not omnipotent. The early things were fine, but in the later stages I can't rub radioactive elements with my hands, right? My physics is a master's degree s level."

After a brief silence, the system said something like a complaint:

"Host, don't forget your own identity. As the saying goes, birds of a feather flock together and people flock together."

"As a person who has made some achievements in the academic field, don't you have a few big friends in the industry who are dedicated to serving the country? When the host unlocks new research results through the scientific research slot, this system will cause experts in the field to defect to the host. You don’t need to worry about the way, I will take full responsibility.”

"I can bring back even people from Caltech."

Huang He was relieved after receiving the system's reply. He began to check the system interface and decision-making system. A negative impact placed in the most conspicuous place immediately came into view.

"Everything is in ruins: construction speed: -50%, factory output: -15%——

The ensuing battles have left us with no time to recuperate and we are now faced with a variety of problems. We need time and even outside help before we can fully recover."

This negative impact is so fatal that the base area itself is in a blocked state. It is hard for Huang He to imagine how much the comrades would have to pay to push the invaders into the sea without systematic help.

But after seeing the decision tree, he already had an idea.

There is actually a explanation for the reason for this time travel.

After this book is finished, I should write about the stars. There will also be Europa Universalis, Victoria 3, and Crusader Kings 2 in the future.
