There is no doubt that the Yellow River is a traverser, and in his previous life he was a Ph.D. in applied mathematics and aerofluid dynamics. Before the crossing, he and a few friends were being interviewed by a certain UP master of Xiaopo Station.

A game called Stars is being discussed, and many of the game's technologies are being seriously analyzed for fun and dog fans about the future viability of many of the game's technologies, but their comments have caught the attention of some special observers.

Huang He and his friends were captured, and in later days several people saw the aliens' activity logs about that day.

"After a period of observation, we have found several very talented scientists among the natives of this planet who are trying to explain advanced technology with backward theories."

"These people are not taken seriously, and we can plunder them back to their home planet and brainwash them into becoming our scientists. If they don't intervene and let them remain in the indigenous civilization, they will only waste their talents."

"Take him and serve us in the future."

"It's a mediocre thing, a daily record."

Due to their contempt for the lower civilizations, the aliens who captured them did not keep them under close control in the first place. After secretly observing for a while, the two of them carried out a long-planned self-rescue campaign.

Luckily, they succeeded. Not only did they escape from the alien spaceship, but they also returned to Earth.

Unfortunately, in the process of escaping, they are not only forced to separate, but also return to the wrong time and enter an unfamiliar body.

On the first day after the crossing, Huang He struggled to sort through the strange memories in his mind, and he found himself at a point in time in the middle of World War II.

In this dangerous world, he is a native of Dabie Mountain. While sorting out his relationships, he saw two characters in his memory that surprised him very much.

Zhang Wanhe! Li Yunlong!

But he quickly accepted this fact, after all, there would be no worse thing to be brainwashed and transformed by aliens. And in any case, this is his homeland.

So he combined the memories of his predecessor and made a meticulous plan for himself.

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

After revealing his desire to go to school, several village chiefs scraped together the cost of traveling to the big city and the tuition fee for the first year.

Huanghe even got letters of introduction from local administrators and letters of recommendation from middle school principals.

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

After passing the written exam with perfect marks in almost all subjects, he successfully passed the interview and physical examination, and successfully walked out of the mountains and entered the Department of Mechanical Engineering.

With his excellent academic and social skills, Huang He became a popular figure in the school, and the principal even exempted him from tuition. Four years later, in 1931, when he officially graduated, he went to the Never-Surrender Comprehensive Polytechnic under the white flag on the recommendation of the school's top officials.

In 1937 he became the first outstanding graduate of the institute to receive the title of "Engineer Graduated from Polytechnic". In the same year, on the recommendation of many mentors, he entered the Second Special Design Bureau of the Northern Power.

Since the outbreak of the War of Resistance Against Japanese Aggression, the Yellow River has been active in Europe, collecting all kinds of equipment and weapons for the motherland on behalf of overseas compatriots.

In 1939, after being invited by Zhang Wanhe, a fellow villager, he was able to get out after relying on the contacts accumulated over the years and paying a lot of price, and returned to the motherland without hesitation to prepare to devote himself to the War of Resistance against Japan.

Like most of the traversers, the Yellow River has a system. Although he didn't know the origin of this system, after experiencing so many unbelievable things, he had already come and gone.

The system remained silent until August 14, 1939, with only the occasional beating progress bar revealing its presence.

Today the system is finally officially opened! He immediately focused his attention, and the system interface came to mind.

As a veteran player, Huang He found that this system is actually very similar to a certain 7+ coloring game in his previous life. However, after careful exploration, he keenly found a lot of differences, perhaps it was just the embodiment of the system finding a template that was easier for him to understand.

Thankfully, most of my old friends are there.

For example, in the decision-making system, by selecting and completing various decisions in the system, certain benefits can be obtained or some negative effects can be eliminated. There is only one slot available for a unit of time slot.

According to the prompts of the system, there is already a decision that is about to be completed without any action on his part.

"Formation of the Academy of Sciences:

We will integrate various research institutes and universities and organize them into new institutions to improve the efficiency of management

Effect: Gain a research slot

Each month, five researchers in the designated field are awarded

Current progress: 38/70 days"

Although the system doesn't explain it, Huang He quickly understands that certain decisions can be passively unlocked based on what he has done, and it doesn't take up a position per unit of time.

For example, the one that is being unlocked must be because the Yellow River has a certain reputation in the field of research. Previously in the 2nd Special Design Bureau, he even participated in the research of the predecessor of the Katyusha.

If it weren't for the help of his mentors and friends, he wouldn't have been able to go home now. As we all know, science knows no borders, but scientists do.

Huang He twisted his body to the position where he turned his back to Makarov, the system was his secret, and he wanted to avoid being detected as much as possible.

Then he frowned and asked the most crucial question.

"System, I need your answer. Nowadays, foreign scientists are very tightly controlled in various countries, and as far as I know, many powerful people are studying or researching abroad. The researcher you just mentioned, how did they come to me? ”

The system is full of humanity and does not hesitate to answer.

"The host doesn't need to worry, everything you get through the decision tree or the research slot, the system will create a reasonable reason and a way."

"For example, the materials can be picked up in the warehouse of the logistics department, and everyone except you will assume that these materials are obtained by you through your own connections, and they will be transported to the base by air or land."

"I have to praise the host, I made the foreshadowing in advance when the system was not turned on!"

Hearing this, the Yellow River still didn't understand:

"What about the results of the research through the research tank? Even though I have some achievements in the field of research, I am not omnipotent. The early things are fine, but I can't rub the radioactive elements by hand in the later stage, right? My physics is also at the level of a master's degree. ”

After a short silence, the system said as if complaining:

"Don't forget who you are. As the saying goes, things gather like and people divide into groups. ”

"As a person who has made small achievements in the academic field, don't you have a few friends in the industry who are dedicated to serving the country? When a host unlocks a new research result through a research slot, the system will cause experts in the field to defect to the host. As for the way, you don't need to worry, I'll take care of it. ”

"Even if it's from Caltech, I can bring it back."

Huang He, who received the system's reply, was relieved and began to look at the system interface and decision-making system, and a negative impact that was placed in the most conspicuous place immediately came into view.

"Waste: -50% Construction Speed, -15% Factory Output

-----------------------

The ensuing battles left us no time to recuperate, and we are now facing multiple problems. We need time and even external help before we can fully recover."

The negative impact of this is so deadly that the base itself is in a state of lockdown. It is difficult for the Yellow River to imagine what the comrades would have to pay to push the invaders into the sea without the help of the system.

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