Cheng Ying is one of the representatives of the martyrs through the ages in terms of historical evaluation.

His loyalty to the Lord is naturally a positive thing.

The rulers of all dynasties, including countless superiors, wished that everyone would be as loyal as Cheng Ying, so they naturally wanted to write a special book and tell people: You have to learn!

And what is the price of Cheng Ying's loyalty?

His own son was thrown to his death.

framed his former best friends and colleagues, resulting in their entire clan being killed.

In fact, Lu Wu only knew that Cheng Ying had protected the Zhao orphans, and he didn't know what else Cheng Ying had done.

If he knew what Cheng Ying had done to protect the Zhao orphans, he might not have taken them in.

After all, he has not been able to accept a group of cronies when he "first arrived", and the situation of the family is not optimistic, how could he take in a ruthless person who will do whatever it takes to achieve his goals.

Cheng Ying left.

Lu Wu personally went to see Cheng Ying's living room, and after looking around, he didn't find anything worth noting.

After repurposing, he thought about it, and it seemed normal?

Even if Cheng Ying has something that can prove the identity of the Zhao family's orphan, he should carry it closely.

And Lu Wu was not sure whether Cheng Ying had that thing or not.

In the following days, Lu Wu kept himself busy again.

The metal workshop has finished making the iron pot that should be made, but there is still a surplus of iron ingots sent by Wei.

In these years, copper was the most widely used metal, and it was inseparable from weapons, coins, utensils, ornaments and agricultural tools.

The rest of the minerals found in the realm are free to be mined and used by the liege, except for copper.

The old Lu family did not have any minerals, and what Lu Wu could use was the iron ingots left by the Wei family.

On the one hand, he used his memory to see if he could reform the iron-making process; While increasing the tools available in the workshop based on his own experience, he plans to build some more furnaces.

Could it be that iron ingots are not widely used in this era and are cheap enough?

Or maybe Wehrch miscalculated the amount that needed to be consumed.

The amount of iron ingots they sent was abundant.

Twenty carts were sent first, and then thirty more, so that after the required number of iron pots had been beaten, there were still two-thirds left.

Lu Wu experimented again and again, and found that the temperature was not high enough, and even repeated forging could not make the iron more pure, and further experiments could not be carried out.

If you want to go further, you need to find a way to get coal.

The rest of the stuff is ready for the experiment to continue.

Poor quality iron is used to make weapons or armor, which is not responsible for small lives.

It's just that it can be used to create a small number of experimental farming tools.

Unable to study metallurgy, Lü Wu turned his attention to people's livelihood, and experimentally took the blacksmith to make a sickle for cutting wheat.

The process of making is very cumbersome, and at the same time, Lü Wu has to "invent" some other tools in the process of making the sickle, causing the craftsmen to be stunned one by one.

In addition to doing business, he also likes to wander around the low hills recently, and he can always find some ingredients that are obviously food, but are ignored by people nowadays.

For example, some wild mushrooms.

Of course, not every wild mushroom can be eaten.

Lu Wu picked a few, and a few of them were very sure that they were not poisonous, but people had not studied the corresponding cooking techniques and did not know how to eat them correctly.

Just as he was researching how to cook the various recovered mushrooms, the caravan that had left before returned.

"Live up to the trust." Cheng Ying didn't look very colorful, and said: "The pottery has been sold; Buying blackstone is also done. ”

Lu Wu was not surprised that Cheng Ying was able to do these things.

It was a successful outing, not only did the goods sold out, but there were no casualties.

After receiving Lü Wu's reward, the samurai and his subjects dispersed happily.

Cheng Ying didn't want to say more, so she wanted to leave.

Lu Wu had to understand the process, and at the same time ask the nobles over there what the situation was.

The nobleman over there was also a small lord, called Liang Zhu.

According to Cheng Ying, Liang Zhu welcomed the old Lu family to do business in the past, but asked the old Lu family to sell the goods directly to the lord, not to his subjects.

Cheng Ying had received an explanation from Lu Wu in advance, so he naturally agreed to Liang Xi.

In other words, the old Lu family can accept both retail and wholesale.

The neighboring little nobleman chose to eat the goods, and the old Lu family passively started a wholesale business.

Lu Wu hadn't had time to count the harvest of the sale.

Cheng Ying directly told Lu Wu that he only collected a small amount of copper coins, and more grain.

As for the coal that Lu Wu attaches great importance to, Cheng Ying brought back a car in the way of picking it up for nothing, and told Lu Wu that if he wanted to get coal again in the future, he could consult with the Liang family, but Liang Yu made it clear that he was not responsible for transportation.

The car was loaded with coal.

The food can only be carried by people, but everyone has no complaints.

"Expensive (people), pound more wheat and rice." Cheng Ying said expressionlessly: "Liang's has many kinds of wheat, and there is also rice. In the next theft, I thought that Jun needed more, and he had an appointment with the Liang family and would buy it. ”

Lu Wu spent most of his time working on food some time ago, and in order to study the fermentation of noodles, he was constantly pounding rice and wheat.

He squinted uncontrollably, turned his head away in order to cover up, and then said in an admiring tone: "Son, talent, only I am lacking. ”

Cheng Ying continued to say expressionlessly: "Theft." It's not to blame, it's fortunate. ”

After finishing speaking, Cheng Ying told Lu Wu that he needed Lu Wu to visit Liang Xi in person to formalize the cooperation.

Lu Wu agreed, and asked Cheng Ying if he needed anything.

Cheng Ying was not polite, mentioning that he wanted to solve some doubts from Lu Wu.

The two talked for a while, and Cheng Ying took the initiative to leave after being solved, pondering to digest the knowledge he had learned, and then continue to ask.

After Cheng Ying left, Qing came over quietly.

He gave a very detailed report to Lu Wu, including what Cheng Ying did along the way, and how he discussed with Liang Xi.

After finishing speaking, he bowed honestly and waited for Lu Wu to give the next command.

Of course, Lu Wu knew that Cheng Ying was talented, otherwise he would not have become a retainer of the Zhao family (the main sect), and even became a minister of the Zhao family.

You must know that when Cheng Ying was a retainer in the Zhao family, it was the most beautiful moment for the Zhao family.

At that time, the Zhao family had two secretaries, and even the side branch also produced a secretary, and the Jin State had a total of six armies, and the Zhao clan directly or indirectly controlled three armies.

How beautiful the Zhao family is, how much of a threat to the monarch, and even to the rest of the nobles, some actions have not been restrained, which has led to the destruction of the door.

However, including the Jin State and other countries, they believed that the demise of the Zhao clan was caused by Zhao Dun's murder of the monarch.

Lu Wu knew that he couldn't take Cheng Ying for his own use at all.

If he had any other thoughts about Cheng Ying, Lu Wu should also be careful and careful, and he must not show his feet.

The time of the visit to Liang was set by Lü Wu thirty days after the return of the team.

That day is also the time when there is enough pottery to accumulate and he will take this batch of pottery with him, and at the same time have plenty of time to prepare gifts.

He wanted to personally contact Liang Yi to judge how big Liang's appetite was, and then evaluate whether it was good or bad to have such a "neighbor" as Liang based on actual contact.

In order to know more information about the Liang family, Lu Wu went to find the old grandmother even if he was not very happy.

"Liang?" When the old grandmother heard this, she frowned slightly and said, "I have heard a little, and his sex is very greedy. ”

This is a little bit of a fact.

Although the two families are neighbors, they are seventy miles apart.

But it shows that the old Lu family and the old Liang family had no grievances before.

This made Lu Wu very happy.

As for whether the Liang family is greedy or not, it is not a problem for Lu Wu!
