"Lord Ren, do you think this method is really feasible?" Tao Jiyuan asked, although burning a stone is like this, he still feels that this idea is a bit fantastical.

Not only him, but also Gu Qiong, Fujiki and other people who were listening next to him all had this thought.

"Whether it's feasible or not has to be tried, after all, isn't there no better way now?" Ren Baqian said.

"Yes. Tao Jiyuan nodded.

"Master Gu, then I'll trouble you to arrange it. ”

Next, Gu Qiong ordered a hundred guards and pressed three hundred prisoners to cut wood in the distance.

The three prisoners were held together with ropes on their feet, and the three hundred prisoners were exactly one hundred groups, and one hundred guards were just able to guard them.

Damo Mountain is an outlier, there are many mountains around here, each of them is green and green, but there is no bare grass in Damo Mountain.

The distance to cut wood is not too close, after all, the daily life of close cooking is almost cut.

In one day, a total of 30 tree trunks with a diameter of more than 20 centimeters and a length of more than 3 meters were brought back.

The prisoners in the mine also stopped digging the mountain, and dragged the thirty pieces of wood to the platform at the foot of Damo Mountain, and then cut them into small pieces.

It took two days to dry and bring back a total of fifty tree trunks, and the first day back was also cut into arm-thick wood, and the next thing was to burn the mountain.

......

A team of more than 100 people, with more than 20 carts and more than 70 forkhorned oxen, marched in the direction of Damo Mountain.

The forkhorn beef is one of the meats that Da Yao often uses, and it grows very fast, half the speed of the curved cow and the like, and the curved horn cow can only mature in five years, and this kind of forkhorn cattle only needs more than three years to be fine.

But this kind of beef tastes very ordinary, it is more chai, and the food of the general army is like this.

The rest of them are to send materials to the Damoshan Iron Mine, once every 20 days, in addition to food, there are some well-made pickaxes, iron cones and other excavation tools, and the tools of the Damoshan Iron Mine are very weary.

"Brigade Marshal, where do you look?" everyone turned a corner of the mountain and saw thick smoke billowing in the direction of Damo Mountain, and someone immediately shouted.

In Dayao ten people for a team, there is a team positive, for the nine products. Twelve teams are a brigade, there are brigade commanders, and they are from the eighth grade. The fifth brigade is a regiment with a captain, from the seventh rank to the sixth grade.

Generally, a regiment with logistics miscellaneous items has 650 to 700 people.

The five regiments were an army, ranging from 3,300 to 3,080 men.

Five armies were one government, about 15,000 people.

This is a whole brigade, and the brigade commander who was in the team raised his head when he heard this, and his face suddenly changed: "Something happened to Da Mo Mountain!" Go back and report the news, one team of people is guarding here, and the others put down their things and come with me with weapons. ”

At the sound of the order, everyone threw aside the things they were carrying, held the long knife tightly in one hand, and marched quickly in the direction of Damo Mountain.

The brigade commander frowned as he walked forward, how could something happen to this Da Mo Mountain? Could it be that those prisoners rebelled? But even if they rebelled, the three hundred guards there would be enough to defeat them.

It doesn't even take three hundred, two hundred people to completely defeat them.

So what's going on with this smoke? It's clearly arson.

While thinking about it, he was worried about the situation of Damo Mountain, and the brigade commander and his people rushed 60 kilometers in only two hours and hurriedly came to the foot of Damo Mountain.

However, unlike what he had imagined was chaotic, the guards at the bottom of the hill were still standing there as if nothing had happened.

"What's going on?" asked the brigade commander hurriedly, looking up at the thick smoke above, like a column of smoke, where you could smell burning.

"Nothing happened, everything was fine. The guard replied immediately.

The brigade commander was relieved when he heard this, and then he was dumbfounded, since it was okay, what was it doing here?

"Sheng Lushuai, you can go up and take a look. The guard didn't understand the specifics, but said, "It was said that it was going to burn Damo Mountain open." ”

How could it be? Isn't this nonsense? As soon as the brigade commander heard this, he thought that he and the others were in a hurry to come for this matter, and the fire in his stomach would not be hit.

"You go back and bring the supplies, and have the other two chase them back, and I'll go up and have a look." Sheng Lushuai threw down a sentence, wiped the sweat on his head and hurried up the mountain.

At this time, Yamagami Yachichi and others stood in front of the wooden house and watched the fire in the distance, a large amount of wood was burning there, and the flames rising into the sky were unapproachable.

"The last general has seen a few adults in the open mountain. "When I saw a few people on the mountain, my eyes shrank. What surprised him the most was not the official positions of Ren Baqian and Tao Jiyuan, but the people who actually saw the flying riders here.

You must know that the flying horse is the empress's personal guard, and it will not be easily touched. What is the origin of the people who came this time?

"This is Lord Cheng Ren of the Middle Imperial Mansion from Arashi, Lord Tao of the Ordnance Division, and Lord Fuji. Open the mountain, count the days, you should have arrived, why did you come by yourself?" Fujiki craned his neck to look into the distance, but there was no one behind him except for the blooming mountain.

Sheng Kaishan cried and laughed: "Lord Gu, I saw a pillar of smoke here from afar, and I thought something was wrong, so I hurried here, and threw everything behind." Now they're back with the convoy. ”

When Gu Qiong heard this, he immediately burst out laughing.

Later, Sheng Kaishan asked cautiously, "My lord, what is this for?"

"What Ren Fucheng said, what's hot or something, anyway, after boiling and splashing water, let's see if it can crack. Gu Qiong touched the beard on his face and turned his head and said.

"This iron mountain is full of iron, isn't this quenching?" Sheng Kaishan said with a puzzled expression. Even if you don't know how to strike iron, you've heard of this quenching.

Isn't it just putting the beaten iron into the water, and what's the difference between that?

"That's right. Gu Qiong slapped his thigh when he heard this. "Why didn't I remember this?"

"Lord Ren, Lord Ren, isn't this quenching?" Gu Qiong turned his head and shouted loudly.

Ren Baqian listened to his words and nodded. "Quenching has a special process and requirements, and the usual quenching is to use hammering to expel the carbon and other substances in the iron into steel, even then if something is wrong, it will crack, let alone iron, you don't have to worry about this. ”

Hearing this, everyone looked confused, anyway, it sounded like this Lord Ren was better than his own people.

"I didn't expect Lord Ren to know how to build. Tao Jiyuan said casually.

"A little bit of it. Let's talk about the fire until the afternoon, and then don't add firewood after noon, I'll go back to my room to rest first. Ren Baqian said hello to a few people and went back to the room.

When it was three or four o'clock in the afternoon, Ren Baqian estimated that the time was almost up, and then he came out of the wooden house, and at the same time asked people to call out Tao Jiyuan, Gu Qiong and others.

After the fire began to get smaller, Ren Baqian instructed: "Lift water and pour it directly on Damo Mountain." ”

Hearing this, the crowd immediately moved, and the others also cheered up.

This time, a place that was only ten meters long was burned, and as everyone poured buckets of water on the mountain wall there, there was a "snort" sound, and each bucket of water was poured into a cloud of white steam, and soon even people in the vicinity could not stand.

Seeing this, Ren Baqian stepped back a little further.

It didn't take half an hour before Ren Baqian waved his hand to stop everyone: "It's almost, go over and take a look after the steam dissipates." ”

And they waited until it was nearly dark, and then they approached with torches.

"Can it really be cracked?" Several people who knew the reason for this matter were not sure in their hearts, and they all set their eyes on Ren Baqian.

"Just take a look. Ren Baqian said, a little nervous in his heart. All I know is theory, if it doesn't work, then it's a shame, and a large number of concave mirrors can't be made in a short time, I'm afraid I'm helpless here.

As the fire shone on the mountain wall, everyone looked at the mountain wall as before, and suddenly felt a sigh in their hearts, could it be that they didn't succeed?

Ren Baqian didn't say a word, until he walked to the position one meter in front of the mountain wall and stopped, carefully looked at the mountain wall, and finally showed a relaxed look on his face.

"Crack, it's really cracked!" Gu Qiong walked over to him and looked at the mountain wall carefully, and suddenly shouted in surprise.

Under the torch light, I saw small cracks all over the Damo mountain wall.

Although it is not very large, the speed of mining along the crack can be at least twice as fast.

"Lord Ren, this method can really be done, Tao really admires it very much, and Lord Ren has made a lot of credit this time. Tao Jiyuan stepped forward to see the crack on the mountain wall, first surprised, and then also showed a congratulatory look.

I didn't expect Ren Baqian to really do this, and it was in such a simple but unexpected way.
