"What is this going on, my lord? What do you want so much coal and stone for? ”

Da Niu couldn't help but reach out and touch the coal and stone piled up like a hill, muttering to himself.

"Don't move, come here!" Blacksmith Feng pulled the bull over and pulled him beside him with a glare.

"Dad, it's the first time I've seen so much coal!"

Looking at his dark hands, Da Niu said shockingly.

After watching Xu Tian let people get these coal stones into a stove that had just been built, Da Niu's expression became even more strange.

However, Da Niu soon found out that he was shocked too soon.

What happened next made him and his father even fall off their eyes.

Xu Tian actually set the pile of coal and stone on fire himself.

"This..."Blacksmith Feng couldn't help it, and took a few steps forward to Xu Tian's side, wanting to say something, but he didn't say it at once.

In his mind, this is simply a misappropriation.

Although he didn't know what Xu Tian wanted to do, he only knew that after the coal and stone were burned, all that was left was a pile of scraps.

Looking at the coal and stone that was gradually burning, Blacksmith Feng tried several times, but still did not speak.

As a result, his face was reddened like a red-hot coal.

Xu Tian watched without saying a word as the coal and stone in the stove gradually burned, and puffs of smoke were discharged from the chimney next to the stove.

This method is stupid, but it is a very effective way to make coke.

When the smoke no longer appears from the chimney, water is poured into the burning coal, and all that remains is coke.

However, the consumption of this method is huge, and the final coke obtained from such a pile of coal and stone is only one-third at most.

Yu Guang saw Blacksmith Feng, whose face was flushed, Xu Tian looked back at him in surprise and asked.

"What's wrong with you?"

"The King... This... What a waste! Burn it out and it's gone! Blacksmith Feng said with a bitter face.

"Haha..."Xu Tian laughed, patted the other party's shoulder, and nodded.

"It's a waste, but it's worth it compared to its role!"

When the coal and stone, which had obviously shrunk by more than half, turned into a small pile of coke in front of him, Blacksmith Feng's expression was still very ugly.

His logic is very simple, these coals and stones that he usually dare not use have been burned out in this way, not bad things.

It's just that during the second smelting, the effect of the coke witnessed by his own eyes, Feng Blacksmith's eyes widened wider than before.

The most important thing in this smelting is this heat.

Although charcoal is good, the biggest disadvantage is that it is not resistant to burning.

Frequent smelting requires a large amount of charcoal, and the fire is not easy to control, which is a great test of the experience of the smelter.

This coke is different, it is very resistant to burning, and the fire is easy to control.

Three days later, after Blacksmith Feng personally made the first plow out of coke according to Xu Tian's method, he deeply experienced this feeling.

…

"This thing, it really works?" After a few more days, the group looked at the strange thing in front of them and chattered about it.

"This is a design designed by the king, my father made it himself, do you think it can be useful?"

Da Niu raised his eyebrows, smiled according to the curved plow, and looked at everyone triumphantly and said.

At this moment, Lu Tianba, Ling Feng and Feng Blacksmith accompanied Xu Tian to slowly come here.

Lu Tianba also personally led a ploughing cow and walked at the rear.

"Your Majesty, do you really want to try it yourself? This is the first one made, and there may be a lot of questions that I don't know yet! ”

Blacksmith Feng said nervously beside Xu Tian.

Although he trusted Xu Tian's design and his own craftsmanship very much, he still couldn't help but feel his heart beating wildly.

This is the first time he has shown his skills, not only Xu Tian, but most of the people in the manor are waiting to see.

Once there is a problem, he doesn't know what to do.

"Try, it's about finding the problem and solving it!" Xu Tian waved his hand indifferently, greeted Lu Tianba, who was holding the ploughing ox, and went straight to the wasteland in front of him...

…

The sharp plough cut through the ground, making it look extraordinarily relaxed.

The curved angle allowed the floating earth to turn to both sides, and the strong plough ox pulled the plowshare and walked forward with ease, bringing up a deep ravine.

Blacksmith Feng personally followed Xu Tian's side, holding a bamboo pen and paper, recording how much time it would take for each plow.

At some point, the surroundings were already full of people, most of them women.

Without exception, they were all stunned as they watched the ploughing oxen plough out furrows on the smooth wasteland.

Countless soils were turned out with fresh grass roots, and the breeze blew with the fragrance of a piece of earth.

The onlookers, without exception, were not good at farming, and they had never seen such an easy way to live for so long.

"Look, I told you, my dad did it!" Da Niu laughed and looked proudly at the people who kept praising him.

The most shocking person is Feng Blacksmith, every record refreshes his new understanding of farming.

Just when everyone was talking, Pang Tong came in a hurry and went straight to Xu Tian, who was plowing the land.

Ignoring the fact that the newly turned dirt would stain his robe, Pang Tongshen walked forward with one shallow foot.

"What's the matter?" Lu Tianba looked at Ling Feng, who was also surprised, and asked.

"It's not like him, isn't he most afraid of getting dirty on weekdays?"

When he saw Pang Tong just now, Lu Tianba wanted to hold him and ask what was going on, but he was pushed away by the other party and almost didn't fall to the ground.

"Who knows! It is estimated that I am going to preach to the king again!

Ay! The king knew the suffering of the people, and he thought about how he could reduce the suffering of the people.

It's a pity that the military advisor doesn't understand the king's painstaking efforts! ”

Ling Feng shook his head secretly, looked at Pang Tong's somewhat funny back, and said softly.

"So, he's asking for his own hardships..."Lu Tianba also shook his head and said.

A moment later, after Xu Tian turned the ploughing ox again, he saw Pang Tong standing not far from him, panting.

"Shiyuan is here! What's going on? Is something wrong? ”

Xu Tianyi grabbed the ploughing cow and looked at Pang Tong suspiciously.

He glanced at Blacksmith Feng, who was following Xu Tian, and when the other party was a little farther away, Pang Tong quickly stepped forward and said to Xu Tian quickly.

"King! If a messenger is coming, be sure to visit you! ”

"Emissary?" Xu Tian frowned.

"That's right! Emissary! ”

"Where did it come from?"

"Zhuge Liang!"

Pang Tong quickly said these three words in a very low voice.

"What do you say? What did he come to Jingzhou for? ”

Regarding Zhuge Liang's sudden arrival, Xu Tian was very puzzled.

The other party didn't say hello, he came directly, what is this for?

"What about people?" Xu Tian looked at Pang Tong and asked.

"Just outside the manor!"

Xu Tian was silent, picked up a piece of soil that had just been turned up, and kept twisting it with his hands.

After a long time, he clapped his hands and said to Pang Tong.

"Let him come here!"

"Come here?" Pang Tong's eyes widened.

"That's right! Come here! ”

After getting Xu Tian's affirmative answer, Pang Tong did not hesitate and ran away again.

After Pang Tong left, Xu Tian beckoned to Blacksmith Feng who was not far away, signaling him to come over.

"I remember you said that the best iron ore is produced in Yizhou?" Blacksmith Feng had just arrived in front of Xu Tian when he heard him ask this.
