I asked you to modify it, what the hell is this fighter jet's engine?

parallel world!

1957 years.

Grain in Ear.

In the Red Star Machinery Factory in Sijiucheng, Gao Xiaoguang, who was about 16 years old, thin and pale, was wearing a four-pocket work suit with two pens in his shirt pocket. He was inspecting the fitter workshop as usual.

It has been a year since I traveled to this time and space.

A year ago, in 2024, Gao Xiaoguang was an assistant lathe engineer in a machinery manufacturing plant. The factory happened to complete a batch of export orders, and the factory director rewarded him with a weekend off.

Single Gao Xiaoguang couldn't contain his inner excitement, so he opened a certain Moji and sent an offline invitation to a dance department girl he had been flirting with for half a year.

After happily checking in at an internet-famous restaurant, the two went to a theme hotel.

When Gao Xiaoguang arrived at the hotel, he was about to perform the difficult moves of the Trust Circle with a young lady in JK clothes who could do the splits, when the door suddenly opened and a group of ruffians rushed into the room and beat him unconscious without saying a word.

When he woke up, it was already 1956, and he had become a teenager in Gaojiazhuang, Mentougou.

Unlike most time travelers who need their parents to offer sacrifices to the gods, the original owner's parents are still alive, and he also has a 17-year-old brother Gao Xiaobin, a 16-year-old sister Gao Xiaoshan, and a 5-year-old sister Gao Xiaolan.

However, the original owner had been weak and sickly since childhood, but he was smart and clever. He skipped to the third grade of junior high school at the age of 15. However, due to long-term malnutrition and poor health, he suddenly had a high fever and fainted after the high school entrance examination, allowing Gao Xiaoguang to occupy this body.

Like most time travelers, when Gao Xiaoguang traveled through time, there was a ten-acre space in his mind. The space was divided into black and white, just like the Bagua diagram.

In the center of the space stands a three-meter-high, one-meter-wide stone tablet with no words, exuding an ancient charm.

Right below the stone tablet is a Baotu Spring. The spring water is sweet, but its effect is not like the magical spring described in the book next door, which can cure all diseases by drinking a sip.

However, this spring water is the best water Gao Xiaoguang has ever drunk in his two lives.

After a long period of exploration, we learned that breeding and planting can be done in the black area of ​​space, and the flow rate of time is 1:3 with reality; while in the white area, time is still, and the still area is opposite to the black area, and no living things can be stored.

During this year, Gao Xiaoguang maintained his image as a top student. He completed the mechanical course that others would take three years to complete in just one year, and with the special approval of his teachers and the principal, he graduated from technical secondary school early.

Currently working at the Red Star Machinery Factory in Sijiucheng as a level 8 clerk in the technical department, with a salary of 33 yuan per month.

After a year of operation, the space has a litter of pigs, two goats, more than 20 pheasants, mallards, half an acre of rice and half an acre of wheat.

The remaining space is used to grow seasonal vegetables, peanuts, a small pond, and two tea trees.

Although the resources in this space are not as good as the incredible space in the book next door, where pigs and sheep can breed infinitely, the resources are enough for the family to have food and drink without worries, and they can occasionally sell some at the pigeon market in exchange for money.

However, Gao Xiaoguang, who knows how to keep a low profile, did not indulge himself and his family in excessive eating and drinking.

Even to improve the food, he would go home on holidays and pretend to go hunting or fishing, and take out pheasants and roe deer from the space to satisfy his family's hunger.

It's not that he is deliberately harsh on his family, but the villagers are all pale and skinny, with rosy faces. If his family members are all rosy-cheeked... Humph, don't disbelieve it, or you'll be reported by pink eye.

You have to know that in the prosperous era in the countryside, even if you pooped in a way that was different from the villagers, people would be suspicious, let alone eating meat and fish every day.

"Senior technician, come and take a look. The lathe we imported from Big Brother is not working." An older worker with his clothes stained with black oil stains, looked anxious and pulled Gao Xiaoguang towards the lathe.

When I walked to the lathe, there were already a lot of people gathered outside. Among them were fifth or sixth level fitters helping a middle-aged man in his forties with gray hair.

"Master, is the motor of this old lathe broken?" asked the young fitter.

"I don't think so. When I parked the car just now, I checked and the motor was still running."

"So what's wrong with this lathe?"

"You bastard, why do you have so many questions? If I, your master, know what's wrong, do you still need Director Hao to call a technician?" The seventh-level fitter glared at his apprentice.

The young fitter smiled awkwardly and hurriedly handed over an enamel cup with the words "Our workers are powerful" written on it.

"What are you all doing gathered here? Everyone, get out of the way and make room for the high-tech personnel to inspect."

When many workers heard Director Hao's unfriendly tone, they all moved aside.

"Senior technician, if this spherical lathe cannot be repaired in the short term, it will seriously affect production tasks. You know how heavy the production tasks in our workshop are. If we fail to complete the tasks, being held accountable by our superiors will be a small matter.

What’s important is that our workshop and our factory will fail to live up to D’s trust and the people’s trust in our factory!”

What the hell...just try to pass the buck, why make a big deal out of it?

Gao Xiaoguang was speechless, but he could not refute it. In this era, once something is elevated to a higher level, difficulties must be overcome, and even if there are no difficulties, difficulties must be created and overcome.

"Director Hao, after careful inspection, I found that the internal bearing of this spherical lathe is broken."

"you sure?"

"determine."

Gao Xiaoguang nodded and pointed to the lathe bearing position. "If you don't believe me, I can remove the bearing for you to verify."

Of course, this is not only his test result, but also the test result given by the space stele.

Speaking of the space stele, it all started from the first time he entered Dove City and came into contact with jade.

Recalling the time when he came into contact with jade in Dove City, the space tablet began to move strangely. The tablet emitted a white light that shot directly into Gao Xiaoguang's mind. After a moment, it absorbed all the information and learned that he had mastered the skills of locksmithing, forging, riveting, welding, and turning.

He firmly believed that as long as he was given the corresponding equipment and his proficiency was improved in a short period of time, he could reach the highest level of worker, level eight.

Just as he was about to exit the space, the ancient stone tablet flashed with light again, and a large number of drawings emerged in the white static space.

"Complete set of design drawings for the F-4 Phantom II fighter, Sidewinder missiles..."

"Design drawing of the F-14 third-generation fighter..."

"Fuck!"

"Not only are there design drawings, but also formulas for various alloy materials?"

"This... is this asking me to rub the fighter plane with my hands?"

Gao Xiaoguang fell into deep thought. From the perspective of nine-year compulsory education, these second-generation and third-generation fighter design drawings, Sidewinder missiles and various material formulas handed over to the country would enable Longguo to speed up the development of second-generation jet fighters.

It can also make Longguo more confident in facing the provocations from the surrounding areas in 62 and 69.

“It won’t work!”

"Once this information is released, the source problem will not be solved. Moreover, the F-4 Phantom Eagle had already been developed in 52.

The F-14 Bearcat was only developed in 62, not to mention the epoch-making Sparrow semi-active radar guidance missile.

If I hand over the information and fail to explain the source, I'll be mistaken for a spy."

To develop in a sneaky way, you must hide first and wait for the right opportunity to take it out.

"Zi~Zi~Zi~"

Following the sound, Gao Xiaoguang saw a picture appear on the stone tablet, and the picture showed a battle scene of F-4 monsters soaring in the air.

Then the scene changed, and an F-4 Phantom froze in mid-air. The aircraft began to be disassembled in a regular pattern, with the parameters of the fighter's components, as well as the manufacturing process and precautions, appearing on the screen...

"This...is this a wind tunnel test?" Gao Xiaoguang was shocked again.

That's right!

The stone tablet shows a wind tunnel being simulated using SolidWorks to conduct wind tunnel tests on the F-4.

"Look at the speed this stone tablet runs at, it's comparable to a quantum computer!"

As a software assistant engineer, Gao Xiaoguang does not understand aircraft design, but his forward-looking vision allows him to judge that the various verification data in the picture require massive calculations.

You know, designing a fighter jet requires multiple disciplines such as aerodynamics, structural mechanics, and materials science.

The stone tablet in front of us actually completed verification of various disciplines in a short period of time, provided various data, and was also able to analyze the design defects and failures of a certain mechanical product.

With this incredible stone tablet and his own efforts, after a long period of accumulation, he will definitely become a faculty member respected by everyone.

To this end, Gao Xiaoguang replaced most of the items in the space with various types of jade for storage.

However, there are limitations on the information that the stone tablet can materialize. It can only materialize one type of technological information on the 1st of each calendar month. As for the stone tablet, it can be used for calculations and analysis of mechanical failures as long as there is enough jade to charge it.

As for making fighter planes by hand, Gao Xiaoguang has no idea of ​​committing suicide. The second-generation, third-generation and even fourth-generation and fourth-and-a-half-generation fighter planes all require a long period of preparation, and at least they can only be implemented after the invincible golden body is forged.

……

The scene returns to the workshop.

Gao Xiaoguang squatted down and was about to remove the broken bearing when a joking but reproachful voice came.

"Xiao Gao! Who gave you the right to dismantle this imported lathe?

Didn't your master tell you when you started working here that even our section chief doesn't have the authority to dismantle this imported spherical lathe on his own?!

To repair this lathe, a Big Brother engineer must be present."
