This is of course a big deal.

In ancient times, people were trying every possible means to improve the quality of iron but were unable to do so. They tried various strange methods and even used human sacrifices in furnaces, but with little success.

Occasionally, if you can successfully train a high-quality sword at once, it can be called a sword, but even then it cannot be mass-produced.

At this time, Shen Bing casually invented a "water drain" and improved the quality of iron every time he produced it... This is amazing, and it means that the iron smelting technology in the Central Plains has generally improved. layer.

However, Benzo waved his hand, and two blacksmiths put two iron blocks into the furnace and pressed the gong... Although there was hydraulic pressure at this time, casting iron did not require too much wind power, so manpower was still used for the time being.

Benz explained:

"The left side is the iron that was smelted before, and the right side is the iron that was smelted after using water drainage."

Soon after the two pieces of iron were heated red, they were taken out. Several blacksmiths hit the iron pieces with big hammers and small hammers... Immediately, sparks shot out and red iron ballast jumped everywhere.

Shen Bing saw the difference at a glance: the iron on the left had more radiating sparks, while the iron on the right had much fewer sparks.

After a while, there were no sparks jumping out on the right side, but there were still broken iron particles on the left side.

Benz explained:

"The iron on the left is more brittle and the iron on the right is more ductile."

"Although the change may not seem big, it is obviously much easier for me to make iron tools."

"The reason is that it is brittle and easy to break, so you have to be careful when working on the details. If you are not careful, it will break and the work will be ruined."

Shen Bing can understand what Ben said.

The quality of iron is hard to tell on the surface. You need to knock it to know whether it is brittle or tough.

Especially when it is red-hot, the blacksmith is used to making brittle iron, so once the quality of the iron improves, his hands can feel it immediately.

Just as he was talking, the iron on the left side broke into two pieces with a "snap", and even when he stopped, he found that the iron on the left side was much smaller... This is because the iron on the left side is more brittle and has more iron ballast during the making. It breaks away from the original body and becomes smaller and smaller as it fights.

Shen Bing simply said:

"It's so good that I made farm tools out of new iron."

Ben responded and bowed to wait for the next step.

Unexpectedly, Shen Bing had already finished speaking and stood up to leave.

This made Benden stunned, and he quickly looked at Qian for help.

Qian was stunned for a while, and then he caught up with Shen Bing in three steps and then five steps, and said:

"Lieutenant General, I think this matter must not be so rash..."

Shen Bing couldn't help but wonder:

"Why not?"

Qian explained:

"Lieutenant General, just imagine, if this iron is made into farm tools and distributed among the people, our iron smelting technology will no longer be a secret."

"And the deputy general doesn't block the news, I'm afraid that the 'Shui Pai' iron smelting will soon spread to other places..."

Only then did Shen Bing realize the reason why Ben and other craftsmen were nervous, fearing that the technology would be spread too early and used by the enemy.

Shen Bing raised his head indifferently and replied:

"It won't be long before the whole world belongs to Qin. So what if it spreads to other places?"

After hearing this, Qian and Ben couldn't help but look at each other.

But when I think about it, I think what Shen Bing said is right. If the world belongs to the Qin State, wouldn’t the technology spread also from the Qin State?

How did they know that Shen Bing had another thought in his mind:

This water drain only improves the quality of the iron a little, which is why they are making such a fuss.

Shen Bing still has more technologies that can produce more mature and better quality iron, and even mass production... So it doesn't hurt to spread this little bit.

Even Shen Bing was prepared to spread it from the beginning, otherwise Shen Bing would not have invented this water drainage.

With Shen Bing's words, Ben Heqian no longer hesitated and started making farm tools out of new iron.

Within a few days, a batch of new iron farm tools were put into the fields.

Farmers can also feel the difference as soon as they use it: because new iron is more tough, it can be made sharper, the components can be smaller, and it has a longer life and is not easy to crack or break.

So there was a lot of commotion right away...

This was caused by the low productivity during the Qin Dynasty.

In fact, the output has not increased significantly after the new iron farm tools were put into use. There is still so much farmland, and the same amount of grain is still produced after farming. It is just that it saves more effort and time during farming.

But low productivity means a low base. Even if the base is low, the improvement will be considerable.

And if a single farmer improves a little, ten, a hundred... when all farmers across the country have popularized new iron tools, the improvement will not be just a little bit.

Even the people are more motivated to farm because of the freshness of the new farm tools... The fields that usually took three days to complete can now be completed in only two days, and the satisfaction is not the same as before.

This naturally alarmed Xu Ying and he once again listed Xintie's iron smelting as one of the goals to record and disseminate.

However, Xu Ying at this time was no longer as interested as before, and was even a little listless.

The problems he encountered were similar to Fusu's.

As mentioned before, farmers are not actually farmers, most of them are aristocrats or intellectuals.

They devoted themselves to agriculture in order to achieve the goal of eliminating war, and based on this they developed a set of peasant theories.

There was nothing wrong with this. They were ambitious and had clear goals.

However, after listening to Shen Bing's story and reasoning about the wolf, deer, and flower, the foundation of the farmer's family was also shaken.

Shen Bing couldn't help but be a little confused when he saw Xu Ying looking listlessly at the people working in the fields.

If it were normal times... Xu Ying would have rolled up his pants and worked in the fields with the others. How could he still be standing beside the fields meditating like he is now.

Shen Bing stepped forward and called out:

"gentlemen."

Xu Ying was awakened, and when he saw it was Shen Bing, he cupped his hands and said:

"But it's the fifth doctor. Xu Ying is rude."

After Shen Bing returned the courtesy, he asked:

"But there is a problem that makes sir think deeply?"

Xu Ying nodded and said thoughtfully:

"As the deputy general said, if planting flowers will only increase the number of deer and thus wolves, then what's the point of planting flowers?"

Shen Bing couldn't help but laugh.

Unexpectedly, several days have passed, and Xu Ying is still troubled by this story, and is still deeply involved in it.

Shen Bing replied:

"Sir, have you ever thought about how the Young Wolf Club would develop?"

Xu Ying replied puzzledly:

"After there are few wolves, there are more deer. There are many deer but few flowers, so the deer starve to death..."

Shen Bing shook his head and said:

"That's not always the case."

"What if there are more deer and then more flowers?"

"Therefore, only Wolf Shao was left, and this was a time of peace and prosperity when the war ceased."

"So planting flowers is not meaningless as Mr. thought, but it is of great significance."

"Otherwise, how can we talk about a prosperous age?"

Xu Ying said "Oh" and nodded excitedly:
Chapter completed!
