Recalling the bad environment in the Central Plains in the previous life, Zhao Si was somewhat embarrassed.

With the passage of time, the difference between ancient and modern times is not only the customs and systems, but also the difference in environment.

Seeing that the sky was getting late, with the current temperature, I was afraid that even in the middle of summer, it would take several days to dry the salt water out of salt, Zhao Si had no intention of waiting, and walked towards Wang Li's barracks with a familiar car.

After eating a hot pot with Wang Li before, Zhao Si and Wang Li became acquainted.

Zhao Si is suffering from the lack of ingredients and empty seasonings.

Wang Li has no seasoning, no cooking means, and no ingredients.

The two of them are gluttons, they hit it off, and they simply became rice partners, Zhao Si is responsible for cooking the ingredients, and Wang Li is responsible for providing the ingredients.

Not to mention that Wang Li is a big dog, this guy said that he couldn't kill cattle without permission, and basically he could get beef out to eat every day.

When I arrived at the place, Wang Liren hadn't come yet, and I didn't know what to do, but the slave was there, and Wang Li ordered that he serve dim sum buttermilk without Zhao Si opening his mouth.

It is worth mentioning that the Qin Dynasty army could bring slaves to join the army.

To be precise, for those who have slaves in their families, the Qin conscription is conscripted together with the slaves in the family.

The situation of slave soldiers is more complicated, some can follow the master before and after, and some are conscripted as auxiliaries.

If a slave kills an enemy and makes meritorious contributions, Qin Law is rewarded, regardless of official slaves and private slaves, as long as the merit is enough, they can get out of slavery.

During the Qin Dynasty, it was already in a slave society, and the number of slaves was not a few, and official and private slaves were an extremely large group, not much less than yeoman farmers.

Zhao Si drank buttermilk and ate snacks at the same time, feeling nostalgic for the technology and ruthlessness of modern society.

Wang Li is indeed not short of ingredients, even bear's paws can be obtained, all kinds of wild game and mountain delicacies, as long as he speaks, there is no problem.

But the problem is that Zhao Si doesn't have enough seasoning, and his cooking skills are not exquisite, let alone that there is not even a wok.

The wok, which seems to have no technical content, is really not low in terms of the industrial level required to make it.

First of all, it should not be too thick, too thick will affect the thermal conductivity.

Secondly, it can't be too crispy, it's too crispy, and the pan will be broken.

Then it can't be too soft and deformed at every turn.

The popularity of iron pots in thousands of households requires a large-scale increase in steel production, and the second means that steel smelting technology has reached the peak of the feudal era.

The current Qin Dynasty is still dominated by bronze tools, and iron tools are generally brittle, and even enough to make daily tools, let alone iron pots.

"So, how did you get the steel smelting?" Zhao Si frowned.

This thing really involves his knowledge blind spot, who has nothing to learn this? What Zhao Si knows is that the carbon content affects the quality of steel, and he doesn't even know how much it is, and he doesn't even remember the melting point of iron.

Iron ore is much more difficult to mine than copper, and secondly, the reserves of iron are much higher than those of copper.

Finally, the quality of peak steel armor weapons in the feudal era was far superior to that of peak bronze weapons.

The problem is here, the Qin Dynasty is already the pinnacle of bronze.

And steel smelting is not even an entry......

The tech tree here is full, the tech tree over there has just sprouted, and the steel smelting has been outrageously slow without large-scale government investment.

A large part of the situation in the Han Dynasty where iron gradually replaced bronze was because there were fewer and fewer copper mines, and it was more and more difficult to mine.

Of course, there is the most critical question.

Technological faults!

The bronze smelting level of the Qin Dynasty was almost the peak of the Bronze Age, and the chaotic times at the end of the Qin Dynasty, the smelting technology regressed, and the key technologies and systems were lost, which was also an important reason why the Han Dynasty had to point to the iron technology tree.

Although the Qin Dynasty also faced these problems, it was not as severe as the Han Dynasty, after all, this era was still relatively primitive and commerce was not developed.

Bronze, although expensive and rare, is barely enough at the national level.

As for steel, with the current difficulty of smelting and the tearful level of practicality, it is better for the First Emperor to continue his studies in bronze smelting, hoping to find a larger copper mine and more advanced smelting technology.

But Zhao Si knew that the bronze smelting technology of the Qin Dynasty had come to an end, and it would be like that if it went up.

Unfortunately, in this era when the quality of bronzes is at its peak and the quantity is barely enough, it takes a lot of courage to open a steel branch.

Steel smelting is not like making paper, you can find a few craftsmen and slowly figure it out.

This thing has an outrageous investment, and it has to be a large-scale investment by official institutions, starting from source industries such as iron ore.

And it is very likely that there will be negative returns for a long time. It is a huge burden on the finances.

There is no doubt that the iron of the early days was definitely inferior to the bronze ware.

"I don't know if the First Emperor has the courage to carry out industrial transformation, this thing is really beneficial for a thousand years!" Zhao Si pondered, one day he pouted the First Emperor, and mentioned it in passing.

It is a fact that the technology of steel smelting has not been developed, many things are useless, and the performance of steel is much higher than that of bronze, which is a fact.

was thinking about how to make the first emperor invest a large sum, but he saw Wang Li walking over with a bronze pot with a happy face.

"The pot you said, I sent someone to get it out!" Wang Li patted the bottom of the pot happily and said with a smile.

Thanks to Zhao Si's heart-to-heart stir-frying, Wang Li complained that Daqin did not have a pot, Wang Li remembered it, and Wang Li, as a glutton, naturally wanted to taste what Zhao Si said about stir-frying, so he sent the craftsmen at home to make a copper pot according to Zhao Si's description.

Zhao Si started, and Shen was outrageous.

However, the thickness is moderate, not particularly thick, but it can't be particularly thin.

Bronze is brittle, it's too thin, it's a little thicker than an iron pot.

It is very good that the copper pot that Wang Li got can look like this, although it may affect the thermal conductivity, but the problem is not big, the fire is fully open, can the pot be cold?

However, it is clear that this copper pot is of great value to the naked eye, and it is impossible to mass-produce it in this era.

Ordinary families, the money earned from a busy year may not be able to afford this pot.

This is a real copper, the kind that can be directly melted into money.

But for Zhao Si, it's not a big deal!

After all, Wang Li is a rich third generation, and he doesn't need to think about the cost at all, and gently stroked the copper pot with exquisite workmanship, Zhao Si's face showed joy.

At this moment, several dishes already came to his mind.
