As early as the Warring States period, lead was used as an impurity in bronze or iron smelting, and it was turned into an alloy to improve its performance. Pen & Fun & Pavilion www.biquge.info

At the end of the Han Dynasty, the blast furnace of striking iron could even produce a high temperature of about 2,000 degrees, if it were not for the lack of knowledge in materials science, industrial chemistry, etc., and the serious bias of science and technology, I am afraid that it would not be Liu Chan's turn to do anything.

Therefore, the difficulty is not in manufacturing, but in choice.

Choose which words to use as a common word!

The three people present were a little helpless about this, this is really not something that can be done by wisdom and knowledge beyond the times, what is needed is a large number of literati and writers to discuss together, split the books, finalize, and even go to the people, collect and record information from the lives of the people.

This is undoubtedly another huge amount of work.

At this time, Liu Chan's heart couldn't help but come up with a candidate, the guy who made meritorious service for his crimes, like a different person, Wei Yi.

To be honest, he did think about throwing this person to a remote place, or directly executing him, after all, he had too many secrets in the lord's mansion. But his subsequent performance made him realize that it was not this person's waste, but that he did not put it in the right place. As a superior, he must give full play to the usefulness of everyone under him, and of course, the most important thing is that there are too few talents under him who can be used at this time.

"Go and call Wei Yi over." After returning to the study, Liu Chan shouted to the people at the door. And when Ma Jun heard these words, he was a little surprised.

"Young master......" Ma Jun hesitated and stopped in the middle of his words, he didn't want to leave an impression in Liu Chan's heart that he excluded his companions and slandered others behind his back.

Of course, Liu Chan knew what Ma Jun meant.

"Deheng doesn't have to worry, Shi Bei should be impressed in the third day, and Lu Meng, the former martial artist of Eastern Wu, can now open his mouth to chant a few strategies on the art of war, and argue a few words about the current situation of state affairs. How this person is now, Deheng can watch with me. Liu Chan smiled lightly, he knew Ma Jun's concerns, after all, he chose this person at the beginning, but he didn't expect that he almost broke something bad in the end, and he was afraid and guilty in his heart, but more of a disadvantage and disappointment in this person.

Not only that, but even Wei Yi's former brothers in the entire mansion no longer paid attention to him, and his subordinates were even talking about him in secret.

But this is the starting point of Liu Chan's intention to save Wei Yi.

This is also another lesson he gave them, about human nature.

No one is perfect, who can be without fault? As long as you don't go to the roots, don't jump to conclusions.

The other more important message he wants to convey is that under his command Liu Chan, he can allow you to make mistakes, as long as you can find and prove your worth.

The so-called daughter buys horse bones, Liu Chan's move is probably like this.

And Yu Dan on the side looked like he didn't know what was going on, and he was a little strange who this Wei Yi was.

It didn't take long for Wei Yi to meet outside the door and was called in by Liu Chan.

"Meet the young master." Wei Yi came in and saw that there were two other people, and he was stunned on the spot, but quickly reacted, "Senior Brother Ma, Mr. Yu, are you okay lately?" ”

Ma Jun just nodded lightly, but Yu Dan greeted Wei Yi with a smile.

From this point, we can see the principle of doing things under the age gap between the two.

Liu Chan made a move, and Wei Yi stood respectfully beside the two of them, but he fell half of his body without missing a trace, and this scene was also captured by Yu Dan in his eyes, and he nodded secretly.

"Wei Yi." Liu Chan called: "How is the matter entrusted to you recently?" ”

Errands? Ma Jun frowned, the young master dared to hand over the affairs to him, what if there was another fork in the last time? Such a silent person will only harm others if he uses it.

However, Liu Chan's words just now made his thoughts not as deep-rooted as before, at least he was still looking forward to what kind of changes would happen to Wei Yi now, at least he was also his companion, wasn't he.

"Young Master, the rangers of Yi'an Hall have been more responsible recently, and they should still have lingering fears after the last incident, and they have implemented strict scrutiny on all the rangers who have come to defect, and reported to the government one by one." Wei Yi took a step forward, just half a body ahead of the two people beside him, no more than a penny, no less, "For all the idle people in the city, Yi'an Tang sent people to warn and rectify together with the government, and now there are few cases of bullying and domination in the city. ”

For the co-optation of Yi'an Hall, it is Liu Chan's recent task to Huo Teng and Wei Yi, such a restless force staying in the city, really can't make him feel at ease, and his treatment of this is like the court's co-optation of Liangshan heroes in the Water Margin, first get a few of the most influential rangers of Yi'an Hall, such as Tang Zhuhuan, and then through internal and external pressure, all the rangers will be under his command little by little.

Since ancient times, "chivalry violates the prohibition with martial arts", and Qin Shi Huang collected the world's soldiers into bronze men. But Liu Chan thinks that blocking is far less than sparse, and can only be a countermeasure made under an emergency, and now he has a lot of time to improve this situation, so he naturally chooses to completely strangle all problems in the cradle.

His idea was to co-opt all the rangers and establish a team similar to that of the later generations of chengguan, from which elite and self-disciplined people would be selected to be organized separately by some public officials in the government, and become another necessary position for urban security - the police.

In Liu Chan's opinion, these rangers are simply the best choice for these positions.

After listening to Wei Yi's report, Liu Chan nodded with satisfaction, he and Huo Teng The latter is in charge of force, and he is in charge of negotiations, so it seems that this person is really suitable for those civilians.

"Ahem." Liu Chan cleared his throat and said, "Wei Yi, put aside the affairs over there for the time being and leave it to Huo Teng, and now I have other things to hand over to you." Liu Chan picked up a piece of paper full of words on the table and handed it out, "Investigate people from all walks of life, record the words and sentences they use in their daily life, and then summarize them and hand them to me." ”

After speaking, he inadvertently stared at Wei Yi's expression, and Ma Jun and Yu Dan were doing the same thing.

Ma Jun was a little surprised by this, how could he not know that Wei Yi was a self-confident, angular and hesitant guy, but now he seems to be doing things very steadily? And between words and deeds, it is quite calm? He couldn't help but look back at Yu Dan beside him, thinking that the stability on Wei Yi's body was something that only people of Mr. Yu's age had seen a little.

At this moment, he actually understood what Liu Chan said before, "Shibei should be impressed in three days", and thought that the young master is really the young master, and there are many more far-sighted people than him.

"There's still a lot to learn......
