Datang: Time travel in two months, wait online, hurry up!

He wanted to ask to see Li Ke, but Li Ke was also in charge of the first advertisement.

The following advertisements are naturally handed over to the people in the newspaper team.

"Boss Liu, I want to publish an article in tomorrow's Datang Daily to promote my shop!"

Shopkeeper Zhang said directly to the head of the newspaper group.

"No problem, what grade of advertising space does Shopkeeper Zhang want?"

Director Liu also had a deep smile on his face when he saw the customer coming to the door.

They really never thought that newspapers could make so much money before!

Just published one advertisement, and earned 1 penny in a day!

You must know that 1 pen is equivalent to the income of selling 1 newspapers!

And this is just revenue, without removing the cost of paper, printing, sales and so on.

This is a pure profit!

It can only be said that their admiration for Li Ke has grown even deeper.

Now seeing someone come to buy advertising space again, he is naturally very happy.

This is the gold master!

"What grade did Shopkeeper Chen buy?"

Shopkeeper Zhang doesn't care about other things, just follow Lao Chen to buy!

Lao Chen is not short of money, but he is short of money again?

"The shopkeeper Chen bought the most high-end front page headlines, once a day!"

When Mr. Liu heard this, he was a good guy, a big money maker!

Immediately introduced him to the price of the headlines.

"Then I'll buy this too!"

Shopkeeper Zhang was also slightly surprised when he heard the number 1 Guan.

But then I thought about it, if I don't make a move, I am afraid that consumers in Suzhou will go to Yangzhou to buy things.

That's too much to lose!

So, he also decisively won the headlines of the day!

"Okay, you prepare a manuscript, and it will be published in Datang Daily tomorrow."

Director Liu's eyes narrowed with laughter, and in just two days, the advertisement has earned 2 consecutive dollars!

Where is this money?

It's a money grab!

The only labor they paid was to use movable type to typeset the manuscript given by the benefactor, and then arrange the layout.

Then it's gone!

Just this one operation, 1 consistent!

Of course, he also knew in his heart that this was based on the circulation and influence of the newspaper.

If the newspaper had no influence, their operation was worthless.

"There's no need to prepare, just copy Lao Chen's manuscript, replace Yangzhou with Suzhou, and replace Chen's shop with Zhang's shop."

Shopkeeper Zhang felt that Lao Chen's manuscript was well written, concise and to the point, so he copied it directly.

Immediately, shopkeeper Zhang returned to Suzhou by boat.

While preparing for tomorrow's sale, he arranged for someone to send money to the Metropolitan Governor's Mansion.

1 pass is not a small amount, and you can't carry so much money with you.

The time soon came to the second day.

When everyone saw the newspaper, they were immediately attracted by the headlines on the newspaper!

It turns out that not only Yangzhou is on sale, but Suzhou is also on sale!

And it is Zhang's shop that is in charge of sales in Suzhou!

In a short period of time, a large number of people read the newspaper and learned the news.

So they all quickly ran towards Zhang's shop.

I originally planned to take a boat across the river to Yangzhou, but since there are also sales in Suzhou, there is no need to cross the river.

All of a sudden, the scenes at the entrances of Zhang's shops were as hot as the scene at the entrances of Chen's shops yesterday!

I saw the deserted scene where there were no people yesterday.

Look again at this moment, the grand occasion of crowds.

Shopkeeper Zhang's face was filled with a deep smile, and he suddenly felt that the price was worth it!

"This old Chen is indeed an old fox, and he has discovered the magic of newspapers a long time ago!"

He felt that the shopkeeper Chen who was the first to advertise in the newspaper was indeed an old fox, and he had seen the effect of the newspaper before.

But he never expected that shopkeeper Chen actually advertised in the newspaper after Li Ke called him over.

Li Ke just smiled and was not surprised that the newspaper had charged two advertising fees in two days.

All this was within his expectations.

Moreover, these 2 passes are just the beginning, and there will be more and more in the future!

"Your Highness, there is news from the steel workshop that the cannon you requested has been manufactured!"

At this time, a person ran over and told Li Ke a news.

Hearing the news, Li Ke's eyes lit up immediately!

PS: The fourth update!corpse.

Chapter 178 Where the shells pass, no grass grows!telescope!

Although he has long believed that craftsmen can make cannons.

But Li Ke was a little surprised at such a fast speed.

"Go and have a look."

Li Ke is looking forward to the performance of the world's first cannon.

Afterwards, Li Ke brought Su Dingfang and others to the steel workshop.

As soon as he came here, Li Ke saw a familiar thing!

cannon!

This gun barrel is too familiar!

I have seen it many times in various photos, books and the Internet in my previous life!

Because his blueprints were drawn according to those cannons in history, the cannons he made were exactly the same as in his impression!

"Your Highness, we have manufactured the barrel according to your requirements and have gone through a series of tests."

"There is no problem with this gun barrel so far, it should meet your requirements!"

The principal gave a brief introduction to Li Ke with an excited face.

According to the method taught by Li Ke, they successfully made the barrel with the lost wax method and clay mold.

And pouring water into the barrel, it was found that no water flowed out from the barrel, indicating that there were no air bubbles and gaps in the barrel wall of the cannon.

Airtightness and safety are greatly guaranteed.

Immediately, they borrowed gunpowder from the gunpowder workshop and put it inside to explode.

The barrel was found to be still intact with no issues.

After testing, they began to grind the inner wall of the barrel, and finally pulled the rifling.

Because the caliber of the gun barrel is large, the space inside must be much larger.

So it's much easier to pull up the rifling.

Using the previously forged high-hardness and sharp alloy as a file, several rifling lines were successfully pulled out of the barrel.

Of course, it must be the simplest rifling.

The more complicated ones can't be achieved with the current technology, but Li Ke's requirements for them are only so high.

So they can be regarded as having completed the task assigned by Li Ke.

"very good!"

"Then proceed to the last test!"

Li Ke nodded in satisfaction.

He took a look at the rifling of the gun barrel, although there were only a few simple ones.

But compared to the smooth inner wall, it is still slightly better.

At least it is much stronger in terms of range and accuracy.

The process can continue to be improved in the future, so let’s build a batch for practice.

"Put wheels on this cannon."

Li Ke gave instructions to the craftsmen.

In the drawings he gave before, in addition to the barrel itself, there are brackets and wheels that carry the cannon.

Put the cannon on the bracket and wheels, and the cannon can be pushed and transported freely.

The bracket can also adjust the height of the muzzle, so that the angle at which the shells are fired can be adjusted.

"Yes, Your Highness!"

The bracket and wheels have also been built long ago. This one is made of wood and is very simple.

Once installed, the cannon can be moved under human control.

"Take solid iron balls and gunpowder and go outside to try."

Li Ke was looking forward to it even more, and gave instructions to the people below.

"Yes!"

Immediately, a group of people came to a large open space outside the steel workshop.

Because of the characteristics of the iron and steel workshop, when the site was selected, it was deliberately chosen in a very remote place.

This is all wasteland, perfect for testing guns!

After setting up the cannon, everyone's eyes turned to Li Ke.

Because everyone doesn't know what the barrel is for.

And what is the use of Li Ke asking them to prepare solid iron balls and gunpowder, as well as a wooden pestle and a stick wrapped with cloth strips.

But Li Ke never let them do meaningless things, so everyone is very curious and looking forward to it.

What happens when these things come together.

"Pour gunpowder equal to the weight of a solid iron ball into the gun barrel, and then compact it with a wooden pestle!"

Li Ke didn't waste any time, and directly directed several soldiers from the Shenji Battalion to operate.

Anyway, the artillery will be handed over to the Shenji Battalion for use in the future, and now the artillery test is also directly let them come, so it should be trained in advance.

Soon, the soldiers of the Shenji Battalion poured gunpowder into the barrel according to what he said, and then poked it in with a wooden pestle to compact it.

"Put the solid iron ball in."

Li Ke continued to command the soldiers, and the solid iron ball was the shell!

The artillery of this era basically fired solid bullets, mainly relying on the kinetic energy of the iron ball to cause damage.
