Quiet!

In the air, there seemed to be no sound at all.

However, that's just seeming.

It's not that the cannon didn't go off.

Rather, the cannon was too loud.

It was so loud that it was no longer audible, but it felt like the ground was shaking, and the turf near the gun mount was lifted and flying. The dust spread like the wind.

All you can see is the cannon firing in full force.

But the sound was so loud that it shook your ears so much that you couldn't hear anything.

It wasn't until the wave of cannon fire had passed that people could hear a burst of sound breaking through the air, making a sharp sound and moving away.

With a bang, six miles away, it exploded directly.

Too far away, they could see the smoke and flashes of light, as well as the blown up turf and dust.

"Wow!"

Seeing this scene, the clansmen were stunned.

I don't know what this is all about.

How can a copper pimple be so powerful?

With this thing, will it take a lot of people to fight a war? Once this thing is pulled out, how many people will not be able to blow it up.

The test was successful!

Han Feng didn't stay to celebrate, but immediately galloped on the horse and ran to the bombing site to take a look.

Han Feng: This is not running blindly.

Instead, Han Feng needs to estimate the range of this cannon.

Then, according to the parabolic equation, the muzzle velocity of this shell is calculated, so that there is the muzzle velocity data of this gun, and the landing point can be accurately calculated according to the gun ruler in the future.

In this way, you can set the gun ruler and other shooting elements, and you can do where you want to hit in the future.

After all, in the final analysis, with parameters, all kinds of shooting elements, there is only one problem left for mathematical calculations.

As a Chinese person, a Chinese student, but has the reputation of being the strongest math student on the planet, when foreigners even have to press a calculator to be able to calculate, Huaxia high school students can even solve equations by mouth and mind.

The mathematical ability of Chinese students is more advanced than that of foreigners, and I don't know where it goes.

"I'll come when I go. Han Feng ran to estimate the range, leaving the words that the women didn't need to follow, and Han Feng went.

Han Feng women, Audrey couldn't help but pull Rachel to see this magical thing that Han Feng created today.

Audrey didn't know how this thing worked.

But, seeing it with her own eyes, she already knew and believed in the power of this thing.

This is artillery?

It's really amazing!

Audrey couldn't help but be surprised, and then she couldn't help but reach out and touch the cannon curiously.

"Whew!

touched it lightly, but it almost burned Audrey's hand.

"Why is it so hot!"

Audrey began to look up and down carefully, trying to figure out where the heat of this thing came from.

But, obviously, she doesn't understand chemistry, she just looks at this bronze cannon, she can see something.

Sure enough, when Han Feng came back, Audrey didn't understand it.

"Han Feng, have you seen it back, what is the result?" Seeing Han Feng coming back, Audrey immediately asked with concern what the result of Han Feng's viewing was.

Han Feng immediately nodded with a smile and said, "The effect is good." It happened to fall in the monster pile, and it just happened to kill a bunch of monsters, and the monsters' bones were shattered and scattered all over the ground. ”

"So powerful?" Audrey listened, and couldn't help but be in awe of this copper guy.

"It's so powerful!" When the clansmen heard Han Feng talk about the explosion scene where the shell landed, they couldn't help but feel their scalps tingle, and they didn't dare to look at this thing in awe in their hearts.

Hearing the clansmen's discussions, Han Feng turned around and said a few words to the clansmen: "This artillery is used to defend the city." In this way, when others come to attack us, we don't have to go out of the city, we have the strength to fight back. So, it's our family's secret. As long as I am still a member of my Wolf family, I can't talk about it to the outside world. Do you hear it clearly? Those who disobey are not from my people, and there will be no mercy for killing!"

"Hear clearly, those who disobey, not my clansmen, will not be killed!" the clansmen were excited and replied to Han Feng in a loud voice.

Now that they heard that this thing was used to defend the city and protect them, of course these clansmen were even more happy and excited.

Because security is at stake in everyone's life, of course they care.

Now that they know, this powerful thing called artillery, although it is terrifying, but it protects them and helps them deal with the enemy, then they will only become fond of this little red guy, and will no longer feel afraid of it, and dare not approach it because they are afraid of it.

The clansmen answered, Han Feng nodded with satisfaction, and then said to Audrey: "Audrey, you take this cannon and pull it into your yard." If I have time, I will explain to you how to use this thing and how to calculate the landing point. The people around me are the most knowledgeable about you, so if I am not in the city, then you must be the only one to operate this artillery. ”

"Okay, Han Feng. When the time comes, tell me about this thing, what's going on. Because I can't read it. Audrey heard Han Feng say that she should pull this newly created family's most mysterious weapon into her yard, and Han Feng would take the time to explain the principle of this mysterious thing to her, and Audrey was even more excited.

Because this is a manifestation of Han Feng's trust in her and his love for her. At the same time, it also proves that her role by Han Feng's side is irreplaceable by other women.

For example, translating books, such as teaching Han Feng to read and write, such as using her extraordinary cultural knowledge to help Han Feng operate this mysterious killing weapon. Don't operate this mysterious killing weapon, that's something that maybe Han Feng's other women who also know words can't do.

After all, cultural knowledge is more than just literacy.

I need to know a little bit about math.

Otherwise, it is obvious that the calculation of the landing point of this shell is really not understood.

Of course, that's all for later.

At the moment, Audrey will only listen to Han Feng's words excitedly, and arrange for the surrounding clansmen to pull this calm two-wheeled cannon into her yard.

Audrey pulled the cannon and walked away first.

Han Feng also let the other clansmen disperse.

He only took Rachel with him, and took advantage of this time to continue to teach Rachel pronunciation.

The first tone that Han Feng taught Rachel was his name, Han Feng.

Because this is the syllable that Han Feng is most willing to teach, and at the same time, Rachel is most willing to learn.

In Rachel's heart, Han Feng's name is the first place.

And her own name can only be ranked second.

Only after the Korean wind.

After teaching for a while, this deaf and mute person learns pronunciation, it is not an overnight thing, and he can't be anxious, so in fact, Rachel's progress is almost the same.

However, Han Feng never got angry at Rachel'er for not being able to understand the trick he taught her pronunciation, shook his face, and scolded Rachel for being stupid.

On the contrary, Han Feng will only keep encouraging Rachel, saying that she is doing a good job.

Of course, in fact, Rachel is not doing very well at all.

However, she has really worked hard.

She couldn't hear the sound made by Han Feng, and she could only imitate Han Feng's voice by learning Han Feng's mouth shape and placing her tongue on the roof of her teeth.

She couldn't hear the imitation of the sound, whether it was like it or not, so she didn't know at all.

Then she can only know through Han Feng how effective her learning is.

This must have made her anxious, and she had no bottom in her heart.

At this time, if Han Feng scolded her, it would definitely make Rachel lose her confidence to continue studying.

So at this time, Han Feng will only keep encouraging Rachel to cultivate her interest in continuing to learn to speak.

"Brother-in-law, we're back!"

At this moment, I heard someone shouting for Han Feng to be my brother-in-law in the distance, and then I could see a team of people and horses hurrying towards here from the southern trade road.

......
