At the border pass, the temperature is much higher than before, but the snow has not yet melted.

In such a cold weather, anyone wants to sleep under the covers.

The soldiers had to come out of the bed, wear ragged jackets and start working.

This winter is too cold, and the barbarians in the north will definitely have a hard time. Previously, the road was closed by heavy snow, and the barbarians could not go south.

Now that the temperature rises and the snow melts, the barbarians who have not starved to death are likely to go south and prostrate and loot.

So they had to rush before they could repair the broken walls.

They don't know how long the wall has been broken, and it can barely be used. The boss has been refusing to allocate money, so they can only find something to repair themselves.

I thought that this time would be the same as in previous years, but who knows what cement was actually sent from above for them to use to repair the city wall!

When the soldiers heard about this, they were quite happy at first, thinking that they still remembered them.

However, after getting the so-called cement, the hearts of all of them sank.

This cement looks like crushed mud, and it is soft when pinched, can it really be used to repair the city wall?

Don't play tricks on them!

What's the use of this soft stuff!

It was cold in the north, and the faces of the soldiers had been blown by the cold wind and had frostbite, peeling and cracking. When the cold wind blows on the face, it's like a knife scraping meat.

Fortunately, it won't take long for them to blow their faces, and they will be blown unconscious by the cold wind, otherwise the smell will drive people crazy.

But Rao is like this, and these soldiers are also holding their breath.

In particular, they had not eaten enough in the first place, and now they had to endure hunger and work in tattered jackets against the cold wind.

They were willing to repair the city walls, but the cement they sent was like plaster, and they were deliberately playing tricks on them!

What's even more excessive is that he actually lied to them and said that they could just wipe it on the city wall!

Are they fools?

There is a lot of anger, and after a long time, he was so angry that he smashed the trowel in his hand.

It is said to be a knife, but it is actually made of wood. A flat plate at the bottom and a handle at the top can smooth the concrete slurry.

"Damn, I'm gone, it's obvious that I'm fooling people!"

As soon as these words came out, the big man not far away glared at him fiercely: "Wang Laosan, you are looking for death!" Repairing the city walls is a big deal, so let's get to work while the sun is shining now! ”

Wang Laosan snorted coldly and said dissatisfiedly: "Of course Lao Tzu knows that repairing the city wall is a big deal, but I have never heard of this cement, it is just nonsense!"

Liu Xiaoqi, look at this thing, what is the use of lying on its stomach? We don't have much time, isn't it in vain to do this now?

It's better to find something to repair the city wall than to waste time now and have no time to repair the city wall when the time comes. ”

Liu Xiaoqi glared at him warningly: "Wang Laosan, do you want to disobey the military order?" Hurry up and get to work! As I said, this cement will be hard after it dries, what are you thinking about! If you dare to talk nonsense and shake the morale of the army, do you still want your head? ”

When Wang Laosan heard this, he reluctantly picked up the clay knife again, and continued to repair the city wall with resentment.

However, he also knew the importance of the city wall, so even if he was angry, he didn't dare to mess around again.

These people are only responsible for smoothing, and other badly damaged places need to be covered with masonry.

A group of people are busy and don't cultivate, but they don't know the bottom of their hearts.

Seeing the sun gradually set, they still did not dare to stop, and continued to work with torches.

An iron order was issued from above, and they had to repair the broken walls within the stipulated time.

Moreover, it takes time for the cement to dry thoroughly, and it can't rain until it dries, so you have to find a good time.

The weather is just right, so they are in a hurry.

It's just that no one can rest assured about this cement that they have never heard of.

At the same time, the capital, under the treasure mountain.

The fire in the glass kiln was raging, and Liu Feng looked at the glass plate pressed out of the mold, and he was excited. Although the glass plate that had just been pressed couldn't see anything at all, he just couldn't help but be excited.

This is the first time they have opened the kiln, and they have successfully fired the glass, how can he not be excited?

He did it!

He really succeeded!

Not only Liu Feng was excited, but the craftsmen around him were also very excited.

They originally burned ceramics, but now they actually want to burn glass!

Where would they do this!

When they first started burning, they didn't have any confidence at all, plus they had heard the name of the Liuluo maniac a long time ago, and they thought that Liu Feng was even more crazy this time.

Who would have thought that they would actually burn the glass out at one time!

A group of people were so excited that they forgot what to do next.

Some people even suspected that they were dreaming, and asked Liu Feng excitedly: "Steward Liu, is this really Liuli?" Did we really burn the glass out of sand? ”

Liu Feng wiped the sweat on his face with his sleeve, and said excitedly: "Yes, this is Liuli!" Quick, send the pressed board to the annealing furnace! ”

When they heard this, they did as they did.

Then he continued to press the glass plate.

Liu Feng personally started the operation, and after a while, he was sweating again.

He didn't bother to pay attention to it, and was busy making glass plates and sending them to the annealing furnace.

The annealing matter only found out when Su Jinli said it. In the past, he didn't know that the glaze still needed to be annealed.

In the past, the reason why the glass cup he fired with water jade exploded after pouring hot water was because there was no annealing.

Therefore, in this glazed kiln, they not only built a special high-temperature furnace, but also built a special annealing furnace.

It's just that the specific extent to which it should be retreated will only be known after repeated experiments.

When Liu Feng thought of this, his originally agitated mood suddenly calmed down.

He suddenly realized that although the glass was burned, the quality of the glass had not yet been determined, so strictly speaking, they had not yet fired the glass successfully.

It's exciting now, it's too early.

Su Jinli saved his life, and he was his master.

Now that she has handed over such an important matter as burning glass to him, if he messes it up, where will he have the face to see her?

Thinking about it like this, Liu Feng became calmer.

He shouted, "Everyone, do a good job! The master said, as long as our glass burning is successful, she will be rewarded! ”

As soon as everyone heard that there was a heavy reward, they instantly felt that their bodies were full of strength, and they shouted in unison: "Yes! ”

The glazed kiln was in full swing, and at this time in the Qin Palace, Chu Yan was still talking secretly with his confidants.

The place of the secret conversation was in Chu Yan's study, where only he and a young scribe dressed as a Confucian were present.

The man looked to be in his twenties, handsome, but his face was not good-looking.
