A little over a week ago.

After deciding to build the aircraft.

Xiaozhao quickly fulfilled his promise:

While preparing various mineral resources.

He swiftly organized a large team.

This team has a total of just over seven hundred people, with about half being craftsmen, totaling over three hundred.

Among the top artisans, aside from Siegfried.

There are three other exceptional craftsmen hailing from various places, equivalent of the 'Level 8 Workers' of the Song Dynasty.

This ratio is actually quite normal.

Take 1959 as an example.

At that time, there were over 70 million skilled workers nationwide, with just over one thousand three hundred recorded as Level 8 Workers by the Ministry of Machinery.

The first generation of submarines, the first missile, the first atomic bomb, and the first space satellite are all inseparable from the diligent efforts of Level 8 Workers.

At present, the population of the Song Dynasty is about one hundred million, far less than the several billion in later generations.

And the number of workers engaged in handicrafts is not as many as in later generations, but producing a few Level 8 Workers is still quite normal.

After all, the key to being a Level 8 Worker ultimately lies in their manual skills.

There is certainly relevance to mechanical and technological foundations, but it's not particularly close.

Some ancient crafts, such as filigree, and kingfisher feather art, are not any less demanding than the requirements for Level 8 Workers.

According to Xu Yun's plan.

In the latter half of the entire manufacturing process.

These skilled craftsmen will undertake crucial molding tasks, directly determining the aircraft's finish rate.

Aside from the artisan segment.

The other half of the team was recruited by Xiaozhao...

Number crunchers.

As mentioned before.

Scientific research is never a one-person effort.

Due to his past life experience, Xu Yun can rely on himself—or rather, must rely solely on himself for the engine design.

Because in this era, no one else has the ability to design engines.

But aside from engine design.

Many calculations require assistance from others.

This bunch of number crunchers were recruited from all over the country, led primarily by Old Jia.

Both Han Gonglian and Liu Yi held mid-to-high positions in the team.

Although they also lack knowledge in engines and fluid dynamics, their calculation skills are top-notch in this era.

In some cases, Xu Yun only needs to provide conditions and equations.

Even if some concepts are beyond the scope, a group of dozens or more can still come up with results through calculations.

During the three or four months from Empress Dowager Xiang's death to the coup, Xu Yun never missed a chance to impart new knowledge to Old Jia and others.

Recently, this even involved some—in part —calculus knowledge.

This team of number crunchers has also been settled within the Artifact Bureau, and Xiaozhao has planned out a large courtyard for them.

When Xu Yun arrived at the courtyard entrance, it seemed very lively:

Perhaps due to limited space.

Even though it was already nighttime, many tables were still set up in the courtyard, with hundreds of people doing mathematical calculations.

Among them were individuals quietly calculating data.

Also groups of three or four working collaboratively.

And some who seemed to have encountered problems, gathered quietly in a corner for discussion.

For example, near the entrance.

There were seven or eight scholar-looking mathematicians gathered, seemingly exchanging ideas.

Upon seeing this, Xu Yun moved to join them, listening with interest.

The first to speak was a middle-aged man in yellow, who pointed at two sheets of calculation paper on the table and said:

"Brother Ou, the valve thickness is one hundredth of an inch, and the nozzle section is set to tianyuan."

"The volume is determined, but why is the result of our calculations not entirely the same?"

A lean dark-skinned man heard this and extended a finger, drawing a line on a column:

"Brother Zou, in my view, you must have calculated the value of the so-called 'axial force' incorrectly."

"Its initial formula should be one-third, not one-quarter....."

The scholar in yellow, surnamed Zou, shook his head, stating:

"No, no, I followed the curve gradient equation taught by Mr. Tongyu, the value must be one-quarter; you are the wrong one....."

Listening for a while, Xu Yun roughly understood the mathematicians' problem:

In simple terms, it is a thrust calculation under the same push-pull ratio for unit sections.

Involves valve thickness and nozzle section, also concerns reflection and speed of sound.

When organizing the number crunchers earlier.

Considering some conceptual issues, Xu Yun specifically teamed up with Old Jia to create a guidance manual.

The manual defined some hyper-dimensional concepts,

Like gravitational constant being 6.67259×10N·m²/kg², speed of light being three hundred thousand kilometers per second, etc.

In other words, just follow these numbers, and report back with the answer.

The guidance manual is like a manual,

Ordinary number crunchers are assigned various data and directly calculate using related formulas.

But while formulas are fixed, certain scenarios don't clearly indicate which one to use.

Therefore, disagreements aren't surprising.

The two seemed to make valid points, with the surrounding scholars seeming to ponder uncertainly.

Just as neither man conceded.

The lean, dark-skinned scholar surnamed Ou suddenly noticed Xu Yun eavesdropping.
