Three days later!

The raw materials for the four-horse carriage, starting from the Royal Palace.

Under the leadership of Cheng Chumo, he went straight to the south of the city.

The four drivers who drove the car were all craftsmen carefully selected by Li Shimin from the Ministry of Industry.

Li Shimin's intention is very simple, if they can succeed in stealing the teacher.

In the future, there will be countless glass cups in the palace.

That scene, thinking about it made Li Shimin feel his blood boiling.

Four carriages, when they arrived at the manor a hundred paces away.

Xiao Hei led the three partners and rushed out.

Except for Cheng Chumo, the other four people all let Xiao Hei and them wait.

"Xiao Hei, go back, your own people."

Cheng Chumo's words are obviously not enough this time.

The four dogs, still looking at each other, scared the four craftsmen a lot.

"Go back all and lie down honestly at the door!"

Li Gen came to the gate of the manor, and with a shout, the four dogs shook their heads and ran to the door, and then two on the left and right.

"Seventh brother, the four truckloads of raw materials have been prepared, my father said, as long as the seventh brother says a word, how much will be needed."

"These four people are our own craftsmen, and they are absolutely trustworthy."

Li Gen nodded when he heard this.

Since it was Cheng Biting Jin who sent craftsmen over, Li Gen still knew very well what he was thinking.

Stealing teachers?

It's impossible to steal.

Because the ratio of the four ingredients is the real secret recipe in this era.

Li Yuan saw the four carriages entering the manor, and immediately walked over.

Don't look at Li Yuan's age now, but his body is still very tough.

"Eldest grandson, what are these people doing?"

"Grandpa, send some raw materials, and my grandson will use them to make glass."

Call!

Li Yuan stumbled and was helped by Cheng Chumo's outstretched hand.

"Grandpa, do you know what glass is?"

Li Gen asked suspiciously.

It doesn't make sense, if grandpa has been living in the countryside, how could he have heard of Liuli? Not to mention acquaintance.

Li Yuan chuckled in his heart.

His eldest grandson is simply a human spirit.

If you are not careful, you will be seen by him.

"How could grandpa have heard of Liuli, just now grandpa himself was careless, and there is a shallow pit under this foot."

Fortunately, at the feet of Li Yuan, the ground is indeed a little uneven.

Li Gen hurriedly instructed that there was light and light for them, and all the roads in the manor should be repaired immediately.

"Eldest grandson, what is this glass?"

Li Gen smiled and explained to his grandfather.

Li Yuan's heart suddenly jumped when he heard this.

Even Cheng Chumo was so excited that he almost lost his breath.

It can be used to make cups, mirrors, decorations, windows for doors and windows, and various small toys for sale.

………

Li Yuan and Cheng Chumo always thought that Liuli was just a cup, but now they can be regarded as increasing their knowledge.

Li Gen's words opened up a new world for the two.

Li Gen raised his eyes and looked at it, if he made glass here in the future.

The walls of the manor will continue to be built.

Although the Tang Dynasty folk customs are simple.

But there are some people who eat people and don't spit out bones.

Even if it is backed by Cheng Yanjin, Yu Chigong, Qin Shubao, as well as Fang Xiang, Du Xiang and the eldest grandson Wuji, the six big trees.

Li Gen also had to tread carefully.

Four carriages were pulled to the center of the manor.

Li Yuan and Cheng Chumo all followed.

Li Gen mixes four ingredients according to the proportion.

"Brother Chumo, let the four craftsmen heat it up!"

"Okay."

Cheng Chumo happily agreed.

The reason why Li Gen said this was because he had already seen that the carriages of the four craftsmen had heated tools and containers.

Since they came prepared, Li Gen was also happy to be idle.

The four craftsmen immediately went into action.

"Childe, how far is this going to be?"

"Just burn it, I'll let someone bring some coal, it's not four hours, I'm afraid it's not enough for the fire."

"Lunch, someone will send it over, thank you for your hard work."

Li Gen smiled and nodded.

"Grandpa, Brother Chumo, let's go back, we can't reach the heat in four hours."

Li Yuan insisted on watching in place, for fear that the four craftsmen would not work well.

Li Gen shook his head helplessly and walked back with Chu Mo.

"Chunmei, go and send the reclining chair to the old man."

"Hmm."

Chunmei said sweetly, picked up the recliner and left.

This chaise longue was handmade by Li Gen, although it was not very delicate.

It was enough to make Li Yuan ecstatic.

Lie on a deck chair and bask in the sun or take a nap.

It's much more comfortable than those stools.

Li Gen continued to read and write, while Chu Mo leisurely drank tea, and after a while, he ran over to see the fire.

The two maids brought lunch over.

Li Yuan and the four craftsmen's meals were naturally different.

Even so, the four craftsmen ate their mouths full of oil, and there was not even a drop of soup residue left.

It was the first time they had tasted such delicious food.

Zhao Si and Feng Wu led Red Sleeves and Tian Xiang to return to the manor from the restaurant.

Li Gen looked at the hour and knew that it was almost there.

"Brother Chumo, let's go over."

Li Gen and Chu Mo walked side by side, while Zhao Si and Feng Wu followed behind with molds and steel plates in their hands.

Steel plates were also brought by the Silence, and steel was a controlled item in this era.

Li Gen walked up to the four craftsmen and saw that the four raw materials had been turned into solutions at this time, and a bright smile appeared on his face.

"Add a fire, and in a quarter of an hour it will be almost."

Seeing that there were still bubbles on the solution, Li Gen said.

Before these people don't deserve full trust.

Li Gen naturally wouldn't tell them that there are bubbles that can't make good glass.

"It's hard work for the four, Zhao Si, Feng Wu, take them down to rest!"

The four craftsmen understood that this was for them to burn the fire and flash people.

After four hours of hard work, he didn't steal any of them.

However, His Majesty told him that everything is up to this son.

The four of them had no choice but to get up and follow Zhao Si and Feng Wu away.

"Eldest grandson, is this it?"

Li Yuan's eyes widened.

"Grandpa, we have to wait."

Li Gen took the utensils that Zhao Si and Feng Wu had put down in his hands.

Keep your eyes on the solution.

Li Yuan and Cheng Chumo saw Li Gen's solemn expression.

The two of them didn't dare to come out.

There is no doubt that this is the most critical moment.

Li Yuan was very happy in his heart, because at this time.

The eldest grandson took away all the subordinates, and the mind of the eldest grandson was a little better than that of the people of the year.

Alas!

Thinking of this, Li Yuan's heart was really mixed.

In this way, the excellent eldest grandson of the emperor, it's a pity that he is a concubine!

Just when Li Yuan was thinking crankily in his heart.

Li Gen moved.

He scooped out a spoonful of the solution and poured it directly into the mold.

Then the mold is placed on the steel plate and rolled vigorously.

"Alright, after dinner, it's time to take shape."
