"Catherine, Sean, Emily, Enniguez, get on your horses and go. I'll leave it to you these soldiers of mine. You are all people with strength and combat experience, and I will rely on you to play to your strengths and help me beat these soldiers. As long as I don't beat them to death, I'll beat them hard if it's okay. ”

Han Feng also said a few words to Catherine, Sean, Emily, and Enniguez, who were waiting for him to say a few words, and in this operation, the people who were responsible for the role of commander and important executor, also said a few words, and then asked them to set off as soon as possible to catch up with the young clan guards who had already run away with a roar in front.

Sean and the others immediately stepped on the horse without saying a word, and chased after their clan soldier team: "Leader, don't worry, we will definitely complete your task!"

Everyone followed, only Emily looked at Han Feng hesitantly, and Rachel beside Han Feng worriedly.

Han Feng understood Emily's worries, and Han Feng immediately said to Emily: "Emily, you don't have to worry about Rachel. I kept her down, not because I disliked her for not being as strong as you, but because I wanted to teach Rachel to speak. Also, I'm going to try to treat her ear. I felt that her ears could healed to hear sounds. However, whether she can't hear or hear, I can teach her to speak, and that's 100% fine. ”

Hearing Han Feng say this, Emily was relieved.

"Boss, then I'll rest assured. Then I'm going to keep up with them. Emily laughed as she spoke, and hurried to catch up with the army.

As for Rachel, she definitely wants to go with her and help Han Feng ensure that these clan soldiers have this training operation. She came to Han Feng just to help Han Feng do things. Now that she has the opportunity to help Han Feng do things, how could she be willing to miss this opportunity to help Han Feng do things.

She would definitely think that Han Feng thought that her strength was not good, and she couldn't hear or speak, so she didn't worry about letting her take risks.

However, these worries were all because Han Feng then pulled her, took her to a place where no one was, compared with her and explained, and immediately began to teach her pronunciation and speaking, Rachel understood Han Feng's intentions.

was also immediately willing to stay with peace of mind and followed Han Fengxue to speak.

Even before she started talking to Han Fengxue, she was already very nervous.

Because only the blind know the preciousness of the light.

Only the deaf and mute can know the preciousness of sound, whether it is heard or spoken.

Teaching the deaf to speak, maybe the people of this world will think it is a fantasy. Even, some people who don't have enough cultural knowledge will think that they are bragging. However, people with common sense of life will know that these are the things that are done every day in the school for the deaf and mute. Teach the deaf and dumb to speak, read and write. Many people who are deaf and mute will not be able to hear even after surgery in this life, but this does not prevent them from speaking.

There are also deaf-mute people, and later the outstanding ones can be used as freshman representatives to speak as freshmen in the university.

That's a great honor.

So, it's really not a fantasy.

Han Feng grew up in an orphanage, and most of the children in the orphanage were abandoned by their parents. Some people are abandoned because they are disabled and disliked by their parents. Yes, when Han Feng was a child, he had seen the teachers in the orphanage, how to teach those children to speak.

Han Feng naturally knew how to teach Rachel to speak.

It starts with making Rachel understand that when she speaks, the essence of her voice is the vibration of her vocal cords.

Han Feng spoke, letting Rachel touch his Adam's apple nearby, so that Rachel could understand through the touch of his own hand that the sound was vibrating.

As long as she can learn the right mouth shape of Han Feng, she will be able to make the right vibration and make an accurate sound.

Even, she can't hear this kind of sound herself, but still, she can say it. Moreover, it can be understood by others.

Although it is still inconvenient to be able to speak and not listen, it is more than half more convenient than not being able to listen and not being able to speak, and it is more than half of the progress.

As for treating Rachel's ear, Han Feng did not fall behind.

After an hour-long course to teach Rachel to make a sound, Han Feng didn't want the effect of the first class, but gave Rachel a lesson.

Then, Han Feng had a very important thing to do, that is, to create a bunch of silver needles that could be used to acupuncture Rachel's ears to treat the major acupuncture points and meridians of her ears.

In the past, Han Feng couldn't make such a silver needle, not that Han Feng couldn't make silver needles, but that he was too poor at that time, and Han Feng had to worry about ten coppers, and there were silver cakes to melt and make silver needles.

However, now there is no shortage of Han Feng gold lumps, not to mention silver cakes.

Moreover, Han Feng is not just about making silver needles.

Han Feng has to do some other things.

That is, as soon as he finished teaching Rachel's class, Han Feng took the clan craftsmen and plunged into the iron melting furnace workshop.

Today, Han Feng has a lot of things to cast.

Han Feng commanded the people to first throw bags of copper into the iron melting furnace and melt them into copper water.

Seeing so much copper, it was all money, and it was directly thrown into the molten iron furnace, and the clansmen talked about it a lot, which was an eye-opener.

Not only have I never seen a person who spends money with a large hand, but I have never seen Han Feng spend money so big that he directly throws bags of copper coins into the iron melting furnace.

No matter what others said, Han Feng told them to go away and go their separate jobs.

Only a few workers in the furnace shed were left to accompany him to make all kinds of strange things.

Right!

In addition to making silver needles, Han Feng also has to cast copper guns and cannons!

It's like telling Hai Weier that you can build a rocket, and sure enough, Han Feng just did what he said and sent Hai Weier a few small rockets that opened her eyes.

It's the same this time.

Since there is already gunpowder that has been successfully tested, how can Han Feng only use it to make a small rocket that can only be seen, but it lacks actual combat effect.

In Sand Wolf City, the reason why Han Feng only made a gunpowder bag for Vivian and Nala to use as a killer weapon to protect Sand Wolf City was because Han Feng had limited time to return to Sand Wolf City this time, and Han Feng didn't have time to make this copper gun and copper cannon, so he could only teach Vivian to learn to make a gunpowder bag first, and then match the catapult he made, and the effect after throwing it was the same as artillery.

So, that doesn't work badly.

This time, Han Feng came back to the northern mine, there is also a molten iron furnace here, and it is located in the wild, and the surrounding area is sparsely populated, not like in Sand Wolf City, testing the power of gunpowder packs, and taking Vivian out of the city for ten miles to avoid people's eyes. Here, in Tieliu City, there are not so many scruples.

Han Feng now directly took it out to test the gun, and he didn't have to worry about leaking secrets.

Because in Tieliu City, there are only his people.

Moreover, in this way, in the process of making copper cannons, Han Feng will not let the clansmen look at it casually. The clan craftsmen who help melt the copper water, Han Feng is strict with them, this is a family secret. Whoever wants to say anything in the shed will be a traitor to the family, and the whole family will be killed.

So under such a proper arrangement, Han Feng began to cast copper cannons for experiments with confidence.

After all, for Han Feng, he has never cast a copper cannon in the earth world, so now he can only experiment and try to make it.

Otherwise, Han Feng would not have made the copper cannon first.

The thought of making a copper cannon instead of an iron cannon first shows that Han Feng's studies in the earth world are not in vain.

Because the copper cannon has its shortcomings, however, it has an advantage, which is what Han Feng needs at present, that is, the copper cannon is not easy to explode.

If the iron cannon is not iron enough steel, it will easily explode. If you blow it up, you'll die.

Therefore, since it is necessary to make a cannon for testing first, it is natural to make a copper cannon with better stability and no explosion.

When the bronze cannon test is successful and the experience of casting the cannon is accumulated, it can be used to cast the iron cannon, and then it will avoid many dangers during the test cannon.

This is a very correct way of thinking.

It's just that it's a bit expensive.

Because of the casting of copper cannons, it is necessary to melt a lot of copper coins.

So, that's really a lot of money. Because it really turned all the copper coins into copper water.
