Finally, Qin Yu got a plan from a craftsman who had experience in firing ceramics that only required 10 blue fragments to successfully upgrade.

Qin Yu was overjoyed.

He carefully read the instructions in the plan.

From this plan, it can also be seen that this craftsman has been forced to do nothing by Qin Yu.

Anyway, Qin Yu told them to think about it as they pleased.

He simply thought of the glaze he fired when firing porcelain.

Although there is not much connection between glaze and the kind of translucent glass Qin Yu mentioned.

But in the end both are very beautiful.

Qin Yu's eyes lit up when he thought of the glaze on the porcelain: "Could it be that this thing has the same origin as glass?"

Things will be simple after that.

He directly called the craftsman over and asked him to describe the process of firing this glaze in detail.

Including the various raw materials that need to be used, all are recorded.

really.

After recording the glaze manufacturing process in detail.

Qin Yu looked intently again.

The cost of upgrading this [broken fired glass craft] is only 10 green fragments!

"System, upgrade it for me!"

Qin Yu burst into tears with excitement.

If he hadn't been so useless and didn't know how to make glass, how could he have fallen into such a state of despair?

If it weren't for such a universal system.

I'm afraid he's really going to suffer a serious blow!

With the complete recipe in hand, glass firing can finally be put on the agenda.

This glass firing process provided Qin Yu with many usable raw materials.

However, it is really difficult to make pure transparent glass.

Later, Qin Yu thought about it and figured it out.

Why do you have to pursue that kind of pure transparent glass?

The only reason why we need to buy glass bottles to hold water is because jade bottles are too expensive and too rare.

All he needs to do now is add a high added value to the outer packaging of the well water.

It is enough for people to know at a glance that this well water is definitely not ordinary.

So.

In today's era.

Even that kind of translucent colored glass is an extremely rare thing.

As long as Qin Yu can produce colored glass, it will be enough to achieve the strategic goals he had envisioned before.

After having this idea.

Qin Yu then selected a set of the simplest methods to obtain raw materials from the upgraded glass firing process.

It was then taught to those core craftsmen.

Let them study it carefully.

And after carefully explaining to them the rough shape of the glass bottle that he ultimately needed.

Qin Yu stopped interfering with their research.

In the next half month or so.

Although there are still craftsmen in Jiyang City who are recruited by the clerk from time to time.

However, these craftsmen who came later were unified into the third square.

After they come here, they can only do some basic work.

September 182.

At the same time that the second batch of 500 bluegrass plants planted by Qin Yu matured.

Zhang Jiao is out of confinement.

"Master, how is the refining of Foundation Establishment Powder?"

Qin Yu came to the alchemy room. He looked at the thin face and the withered Zhang Jiao that even the Silver Spirit Grass could not repair. He was full of expectations in his heart.

Zhang Jiao's physical condition looks very bad.

But at this moment, his eyes seemed to be shining brightly.

Qin Yu understood in his heart.

This is obviously because Zhang Jiao transformed all the energy in his body into spirit.

It's like a warrior transforming the qi and blood in his body into true qi.

Scribes can also transform the qi and blood in their bodies into spirit.

Their brains consume a lot of energy when working quickly.

These scribes did not eat much on weekdays.

But once they get to the point where they need to significantly improve their brain power to calculate.

This kind of consumption is terrifying.

The same goes for Zhang Jiao's alchemy.

Alchemy is inherently a delicate job.

Zhang Jiao wanted to perfectly extract the medicinal power contained in Qingli Grass and Silver Spirit Grass.

It will inevitably consume a lot of energy and blood.

But Qin Yu didn't expect it.
