Whether it is daily necessities, handicrafts, or farming tools, they can all be handed over to the supervisor.

In addition, the Chief Engineer was also good at civil engineering.

It is an important sector in urban development.

Therefore, it is the best choice to entrust the production of cement to the construction supervisor.

Of course, the most important thing is that confidentiality is extremely high here.

No need to worry about technology leakage.

Now that Li Er has arrived, all the officials have started to work hard.

Supervisor Liu Rengui had already called all the craftsmen together.

Speaking of which, these are the top technical personnel in Datang.

It is not possible to have the opportunity to see the emperor on ordinary days.

So for them, don't even think about staying up late tonight.

I am willing to endure him for three days and three nights.

This opportunity to show off is a once-in-a-lifetime opportunity!

Li Er explained his purpose in a concise manner.

Next comes Zhuang Zhou’s technical guidance work.

Various raw materials began to be available one after another.

Limestone, coal slag, iron ore powder, gypsum.

And other raw materials, everything is available.

As for the mold, Zhuang Zhou had already seen it.

Damn it!

It's a stone mill.

This is a bit unexpected.

But if you think about it carefully, it is true.

In this era, there seems to be no other tool for grinding into powder except stone mill.

Not to mention, Zhuang Zhou saw his grandmother use this kind of stone mill when he was a child.

I usually grind beans and make tofu.

Grind glutinous rice to make dumplings during the Chinese New Year.

All of them are made with stone mill.

The wisdom of our ancestors is really amazing.

But now you can no longer see stone mills.

So now we use stone mills to grind powder to make cement.

It really has a unique flavor.

The torches lit up brightly.

Because Li Er was at the scene.

Every official in the Works Supervisory Office personally participated in the labor.

And they were all rushing to do the work.

Afraid of doing less.

This scene is so interesting.

Employees all want to perform well in front of their boss.

Even across thousands of years, this is still the case.

It seems that this is also a kind of cultural heritage!
