Back to Datang Jianzuo City

Chapter 63 Salty
Never look at the ancients with the eyes of modern people!
This is Ding Yi's perception in the past three months.

When Yu Chigong rushed towards the concrete wall with a one-foot-diameter log in his arms, Ding's jaw fell to the ground!
"Boom!"

"You Yuchi old black, you rushed over and didn't say a word!" Cheng Yaojin shouted angrily from the side.

Blackie, no!Yu Chigong had already dropped the log at this time, returned to Li Er's side and pointed to the undamaged wall, and said, "Your Majesty, this cement wall is indeed strong! If the earth wall was smashed by the minister just now! "

"Well, this cement is really strong!" Li Er replied.

"Your Majesty, why don't you push a siege engine!" Qin Qiong suggested.

After a while, someone came with a siege engine, and six soldiers pushed the siege engine towards the city wall eight feet away!

"Boom!" I saw that the wall did not move at all, and the sharp end of the log on the siege vehicle was knocked flat because it was about to hit the city gate!
Continue to increase the size, ten soldiers pushed and bumped together!
fine!

Two siege engines, thirty soldiers!
nothing!

I have to continue, Li Er stopped it!

"Don't try it! This cement wall is really strong!"

Ding Yi replied: "Your Majesty, this is just the simplest. If you add iron bars inside when pouring, half the thickness can almost achieve this effect!"

Cheng Yaojin patted Ding Yi on the shoulder and said, "Haha! You kid can make such a thing! It's very useful! I heard that this cement is easy to fire, but is it true?"

"Everyone, this cement is fired with stones, and 50 people can burn tens of thousands of catties every day! It can be mixed with sand and stone to pave roads and build city walls! It can also be mixed with fine sand as an adhesive instead of glutinous rice. Pulp! It's just a little, it's not easy to preserve, and it can't see the water." Ding Yi returned.

Li Erchang said imaginatively: "With this cement, how can we worry about not being able to build a high wall on the border of the Tang Dynasty, and why worry about foreign enemies!"

"Yes! Your Majesty! This cement is easy to make, and the raw materials can be found anywhere, leaving more than half of the cost! Moreover, this cement can be solidified in just three days, which is several times better than glutinous rice paste!" Changsun Wuji added.

At this time, it was time for Du Ruhui to enter the stage, and said: "Your Majesty, I went to Shiping a few days ago. The Marquis of Shiping has already ordered someone to use this cement to build a road from his mansion to Shiping County. It's like a complete piece of bluestone paving. With this cement, the transportation problem of my Tang Dynasty has also been solved!"

"Haha! What Keming said is true! Ding Yi, you have made a great contribution again!" Li Er didn't know how many times he had praised Ding Yi during this period, and no one had ever done such a thing!
"This is just what the minister should do!"

"You kid, you're still humble! Haha!" Li Er scolded with a smile.

The others also looked at Ding Yi with a smile, this brat is not bad!It's much better than those things at home!
Following Li Er and others back to the Lizheng Hall, everyone sat on the brocade pier, and Ding Yi was pulled to his side by Cheng Yaojin.

"Ding Yi, the potatoes before, the cement this time! How do you think I will reward you!" Li Er said helplessly.

"Your Majesty, there was a lack of salt before!" Fang Xuanling suddenly reminded Li Er.

Li Er's eyes widened, and he said: "I forgot, you kid said that you can solve the problem of salt shortage, but did you really mean it?"

When the generals in the palace heard this, they looked at Ding Yi in surprise, this kid... Tsk tsk!It's a pity that the old man has no daughter!
"Uh...this..."

"Just say what you have! For the sake of cement, I won't blame you!" After all, it's a child, and it really can't be solved!

Ding Yi thought for a while and said: "Your Majesty, I have a solution!"

Li Er was excited, and so were the officials.This kid really has a way!
"What can I do?" Several people hurriedly asked this question.

Ding Yi asked Li Er for a few people and went to prepare things!
After a while, a fire was lit in the Lizheng Hall to grind the obtained brine.Add water and stir, and pass through the burlap several times.I used the two layers of linen cloth with charcoal grains wrapped in the middle several times, and I saw the blue solution flow out.

After the fire was very large, the solution was poured into the iron pot and kept burning.

Ding Yi stood up and beat his back, a little tired!

"Boy, is this all right?" Cheng Yaojin asked.Is it that easy to make salt?

"When the water is boiled dry, it becomes salt!" Ding Yi explained to everyone.This is not the edible salt of later generations, but the current technology is good enough to do this.

Li Er trembled again. After mixing it with water like this, after several times with cloth and charcoal, there will be salt!

"And that makes the salt?"

Ding Yi didn't answer him, and when the water boiled dry, there was a large piece of salt in the iron pot with some blue color.

Ding Yi stepped forward and snapped his nails to taste it, shit!So salty!

Everyone was startled when they saw Ding Yi whose face changed, thinking that he was poisoned.

"Boy Ding, are you okay?" Cheng Yaojin asked eagerly.

Ding Yi found water to rinse his mouth, and said, "Ah! I'm so salty! I don't want to eat salt these days!"

Everyone's faces were weird, and they also reacted!

"Haha! You skinny monkey! You really should be beaten, but my old Cheng thought you were poisoned!"

"Hahaha, salt...is that how it's made?" Li Er couldn't believe it.

The others were also excited, and hurriedly stepped forward to snap their nails and stuff them in their mouths!
Um!This is the taste!This kind of quality is worth hundreds of coins per catty, and ordinary people have no use for it.Just use a vinegar cloth and put it in when cooking!
Ha ha!A group of men were crying and laughing, which gave the Lizheng Palace a strange smell.

"Your Majesty, this is actually the chemistry I mentioned! This is just one of the applications that is not too difficult!"

"Oh? This way of chemistry is so magical! It seems that I want to be simple!"

"Yes, Your Majesty! I didn't expect this chemical method to be so practical! The Marquis of Shiping is a great talent!" Changsun Wuji and others followed Li Er and sighed.

After everyone sighed, Ding Yi listened quietly.Until Li Er looked at him, he said: "Your Majesty, I actually have something I would like to ask you to agree to!"

Li Er looked at Ding Yi with eyes full of admiration, and said, "Say it!"

"I want a salt mine! It doesn't have to be too big!"

Li Er looked at Ding Yi strangely, and said, "I'm sure, but what do you want the salt mine for?" This kid always has some weird ideas, which can be realized in the end. What are you doing!
Ding Yi also knew that the bittern salt was produced, and the salt mines in the whole country would probably be controlled by Li Er, after all, it was the lifeline!He wants to make alkali, baking soda, soap... many things need this bittern mine!Halogen salt = stone alkali = condensation stone = medicinal material!It is an industrial foundation!
"Your Majesty, I'd better wait for the minister to test it out before reporting to you. It's just an idea now!"

"So, you can do it! I fully support it!"
