Start with a blacksmith shop.

"**Success is not yet achieved; comrades must continue to strive.**"

After Li Zhenhua finished speaking, he walked to the pile of unfinished knives and took out five of them.

Upon arriving at the belt sander, the five blades were clamped onto the fixture in sequence.

Under their watchful eyes, Li Zhenhua turned on the belt sander, and the motor spun at high speed, causing the sanding belt to rub against the blade of the dinner knife.

Soon the clamp was pushed to the limit position, and Li Zhenhua knew that one edge of the knife was now complete.

Remove the entire fixture from the base, flip it over, and grind it again on the belt sander.

When Li Zhenhua took all the blades off the belt sander,

All five knives had their blades sharpened, and after being inspected by Li Zhenhua, their errors were all within a controllable range.

These five sharpened dinner knives are a meaningful testament to Li Zhenhua's identity.

This proves that the jig he made is indeed useful, so he doesn't need to waste time on the sharpening process.

"Guoba, the task of sharpening the blade is now yours. You sharpen it, and then Liu Xiaodong will be in charge of the rough grinding. I'll use high-grit sandpaper to fine-grit the blade."

We aim to complete the final acid pickling process on all the knives within the next three days.

After Li Zhenhua made the arrangements, the three of them began to do their respective parts of the work.

Three days passed in a flash. All the knives that had been processed by the three of them, and finally polished with 1200-grit sandpaper, were placed on a felt cloth, awaiting the final step.

The remaining pickling is the simplest step; once the pickling solution is prepared...

Once you connect it to 24V power, you don't need to do anything; just keep an eye on the time and retrieve the knife when the time is up.

The raw materials that Li Zhenhua and his team initially purchased were eventually used to forge 1,316 knives.

In addition to these finished products, there are 103 defective products.

Guo Shugui's attention was completely drawn to the finished dinner knife, while Liu Xiaodong stared blankly at the defective product.

"Hua Zi, this knife is absolutely gorgeous! I feel like you set the price a bit too low before. This time I've really made a killing."

Hundreds of knives placed together, their blades reflecting a cold glint in the sunlight, create a truly awe-inspiring scene.

"Hua Zi, all these knives are mine now."

Guo Shugui looked at the batch of knives and hurriedly asserted his ownership of them, fearing that someone else would snatch them away.

After hearing Guo Shugui's words, Liu Xiaodong also chimed in from behind.

"Nobody's going to take it from you, look at how impatient you are."

Hmph, right now the person you need to curry favor with most is this blacksmith next to you.

"As long as he's around, wouldn't we be able to get as many of these knives as we want?"

Upon hearing Liu Xiaodong's words, Guo Shugui quickly realized what was happening.

She rushed to Li Zhenhua's side and fawned over him.

However, Li Zhenhua did not pay any attention to the two people. Just now, he received a message in his mind.

"I've got it!" (Humi-level) Brain Brother said.

Brother Yan said, "This is too simple; I understood it all."

Brother Shou said, "A piece of cake, I can make them all."

{Proficiency: 1137/100000, upgrade requirements unknown, please continue exploring.}

Upon receiving this message, Li Zhenhua was very excited.

If there weren't two other people present, he would have jumped up immediately.

After working hard for half a month, his skill finally leveled up.

The skill description also includes the level name, Humi.

This unit of length is not used much in our daily lives; it is mainly used in places like factories.

In factories, the tolerance of 5 mils is often referred to as "mil". The "mil" in "mil" is the same as "humi". The terms "tiao" and "dao" also refer to "humi".

The conversion between the centimeter and other units is as follows: one millimeter equals ten micrometers, one hundred centimeters, and one thousand micrometers.

However, Li Zhenhua was somewhat puzzled, as he had originally thought the next level would be millimeter.

Now, things are really going well; we've bypassed Simi and arrived directly at Humi.

Li Zhenhua pondered this matter, guessing that it might be related to the abolition of the silk rice system in the year 4681 of the Yellow Emperor's calendar.

Internationally, after the millimeter, the micrometer, the sterimeter, and the humi are not included in the International System of Units (SI).

These are merely supplementary units of length; in formal settings, the units of length, such as silk and hu, are not used.

The system may have thought that going straight to the micrometer level was too much, so the intermediate filament-scale process was discontinued.

However, since "humi" (or "si") is still used in daily life, it has been given an additional level.

This level represents a significant improvement compared to Li Zhenhua's current level.

This is no small improvement; it directly increases the accuracy by a hundredfold.

With this level of precision, ordinary machining processes are no challenge for Li Zhenhua.

Guo Shugui and Liu Xiaodong were envisioning the knife's future appreciation potential, but they forgot that...

Although this knife was forged by Li Zhenhua, there are quite a few in existence, over a thousand. Moreover, how many more Li Zhenhua will make in the future is up to him.

After completing his skill upgrade, Li Zhenhua began to make plans.

He was thinking that he should also have a knife made for the competition.

"Guoba, Fatty, you two stop talking for now. Fatty, go drive the pickup truck to the door."

Guoba, why don't you give your purchasing department a call? We'll come directly to your purchasing department in a bit.

Li Zhenhua looked at the dinner knives he had made, all piled up in his home, and thought it was nothing unusual!

Since that's the case, it would be better to let Guo Shugui take all the knives away now.

When Guo Shugui heard Li Zhenhua say that, he knew he should deliver the knife to his company as soon as possible so that he wouldn't have to worry about someone intercepting it later.

Although no one is competing with him now, who knows what will happen in the future? It's best to secure the gains now.

The pickup truck pulled up in front of the blacksmith's shop, and Li Zhenhua and Guo Shugui each came out carrying a large box.

Arriving at the pickup truck next to the city wall, I placed the box I was carrying into the cargo bed at the back of the truck.

The three of them worked together to load five full cardboard boxes and one less than full box onto the pickup truck.

Once the car was loaded, Liu Xiaodong started the engine, and Guo Shugui and Li Zhenhua sat in the back seat.

At this moment, Liu Xiaodong asked Li Zhenhua.

"Zhenhua, this batch of knives is finished. What do we do next?"

Have you mastered all your skills? Shouldn't we start crafting the knife for the preliminary rounds?

Upon hearing the question, Li Zhenhua thought to himself, "It's time; it really is time to forge the knife for the competition."

"Fatty, you're right. Let's each rest and recuperate at home for a day tomorrow, and then we'll officially start making the knives for the competition the day after tomorrow."

Guo Shugui, who was playing with a kitchen knife in his hand, immediately became interested after hearing this.

He quickly turned his head to look at Li Zhenhua beside him.

"Hua Zi? You're starting work already? That's great! I'd love to see how your process for making the competition knife differs from the process for making my dinner knives."
