Da Qin: At the age of six, I beat Qin Shihuang at the beginning

Chapter 104
Qin Mu looked at the sand gradually melting in the cauldron, and said, "Of course. Glass... oh, it's medicine jade, which is actually formed by melting sand and solidifying it."

"As for the firmness and transparency of the glass, it has a lot to do with the composition of the sand."

"In my hometown, some glass can even prevent crossbow arrows from shooting at close range after adding certain auxiliary materials!"

He didn't say bulletproof, and Zulong probably wouldn't understand what a bullet is.

However, crossbow arrows are still no problem!

Zulong's expression changed dramatically.

Yaoyu, isn't that extremely brittle?

Even if it falls on the ground normally, it will be torn apart?

And after adding something, it can actually prevent the crossbow directly?

You know, Daqin's crossbow arrows are already quite developed.

Shooting at close range can directly penetrate a few inches into the flesh!

Hitting weak palms and other parts can even penetrate directly.

Some with excellent performance can even shoot through thin bronze plates.

Now that the two armies are at war, the defense against crossbow arrows can only rely on heavy shields.

But the shield will affect the line of sight!
Often experienced generals will arrange cavalry flank raids before releasing arrows.

You blocked the crossbow, but the cavalry has already detoured behind you!

However, this glass can actually prevent crossbow arrows?
Besides, according to Qin Mu, the transparency of this glass is also very high, and it will not block the line of sight at all.

Doesn't that mean that there is no need for a shield at all?

Even, build a mobile glass house for the general, so you don't have to worry about safety, and it doesn't affect the observation of the battlefield!
"Mu'er... this glass..."

Qin Mu guessed what he was thinking, and poured cold water on it: "Don't think about it! Daqin has limited conditions and can't make that kind of glass at all. Now, I can only work on transparency, this kind of glass is very fragile!"

Li Si was listening, also a little unbelievable.

Can glass prevent crossbow arrows?

This is a bit of an insult to common sense!

If it wasn't for Qin Mu not showing it, otherwise he would have thought that he really had a brain disease, all of this was his fantasy!
While the few people were talking, all the sand in the furnace had melted and turned into a pot of viscous liquid.

"Ada, where is the borax I asked you to find?"

Ah Da hurried forward and handed over an oilcloth bag in his hand.

Qin Mu took out a handful of white powder from it, which was borax.

After slightly estimating the weight, Qin Mu sprinkled three handfuls into the pot.

Then, let Ah Da also hold an iron rod and stir vigorously.

After stirring for more than half an hour, the borax was fully mixed in the solution.

The originally cloudy liquid became somewhat transparent.

"Keep working harder! Wait until the bubbles dissipate!"

"Li Hei, stop over there and burn the tin I gave you earlier!"

The melting point of tin is not high, so he didn't ask Li Hei to heat the tin until now.

In the end, the processes in both furnaces were completed almost at the same time.

The glass liquid has reached the level of transparency and uniformity, and the tin has completely turned into a liquid.

Qin Mu ordered, and poured the glass solution directly into the tin pot.

Then, he asked people to extinguish the fire, closed the lid and didn't even look at it, and directly called Zu Long and Li Si to leave.

Li Si frowned.

Is this the end?
Are you kidding me?

What about Yaoyu?
What about glass?
Isn't it colorless and transparent?
You just poured him into that pot of silvery tin liquid, no matter what happened?
The glass liquid is indeed transparent, but with the addition of silver tin liquid, it is strange to be transparent!
"Ahem, brother Zhao, this young master's joke is too big..."

"It is colorless and transparent, and it can withstand crossbow arrows..."

"Look at that pot of tin liquid, how could it be made?"

Zulong, who was originally full of confidence in Qin Mu, also hesitated.

He saw with his own eyes that the sand was indeed a colorless and transparent liquid after it melted!
If the fire had ceased directly at that time, the glass might have been formed!
But why did Qin Mu pour it into the molten tin?

If the two want to mix, wouldn't they be colored?

Alas, it seems that I still expect too much from Qin Mu.

What kind of colorless and transparent glass can't exist at all!
If it is really possible to smelt it with sand, then what are you keeping those crystal cups in your palace for?
Throw it all away!
Qin Mu took Zulong and Li Si around the village for a long time.

No matter what the two of them asked, he kept his face mysterious and refused to speak.

It was not until two hours later that he finally returned to the stove with the two of them.

With a confident face, Qin Mu stood by the stove: "Father, here comes the glass!"

Zulong did have a wry smile on his face.

After turning off the flame for such a long time, the liquid in the stove may have condensed into a ball of tin lumps by now!
Glass, maybe?

Li Si coughed lightly: "Cough, young master, why don't we open it, actually..."

Qin Mu raised his eyebrows and interrupted him: "Lao Li, you don't believe me, do you?"

Li Si's expression was tangled, he really didn't believe it.

The reason why Qin Mu was not allowed to lift the furnace lid was to save him some face.

However, this cannot be said!
He said awkwardly: "Young master, how could I not believe you... just because I believe, so..."

"Don't say it!"

Qin Mu laughed loudly, and directly lifted the furnace cover.

"Ok?"

Rao Zulong and Li Si had already given up hope of seeing the glass, but they couldn't help but look at the stove.

I saw that there was a piece of solidified tin in the stove.

Where are the traces of glass?

"Mu'er, this..."

"Ahaha, Dad, come closer and look carefully!"

Zu Long stepped forward slowly, and he didn't realize something was wrong until he was two steps away from the stove.

On top of the solidified tin, there seemed to be another layer of something!
He stretched out his hand to touch, and although his fingertips were still three minutes away from Xi, he couldn't stretch any further!

That layer of substance is colorless and transparent, as if it doesn't exist!

"This……"

Zulong looked up in shock: "Is this glass?"

Lismond is gone.

Your Majesty, what's the matter?
There was obviously nothing in the stove except the tin block!
He also stepped forward, reaching out to touch like Zulong.

As a result, before touching the tin block, there was already a warm touch from the fingertips!
There really is something!
It's just...he can't see it!
Recalling Qin Mu's description, Li Si was completely shocked!

That magical glass really exists!

Qin Mu took an iron piece and knocked on the edge of the stove twice.

Afterwards, Dian Wei stepped forward and took out the glass with a little force.

In the sunlight, Zu Long and Li Si really saw what the glass looks like.

Like a crystal without any impurities, the light is not blocked at all!

At this moment, neither of them said a word.

Words can no longer describe the feeling in their hearts!

A six-year-old child, using worthless sand, made glass that is purer than crystal!
