Li Kang returned to Xin'an Town in late April.

At this time, because of the addition of more than 4,000 new troops, the construction speed of Zhongxian Road has doubled sharply, and the southern end has almost been repaired to the first post station - Li Kang ordered that a post station be built every 20 miles on Zhongxian Road for passengers to rest and eat - the speed is not fast.

On the side of Xin'an Town, Xinshen Road (Xin'an Town-Shennong Town) and Xinqi Road (Xin'an Town-Qihuan Town) are still advancing step by step, and it will take some time to complete.

After nearly three months of hard work, although it is far from the legendary x x speed of one floor a day, there is no shortage of cement, green bricks, slates, wood, etc., so that Yu Wenkai has made more than 20 suites.

Of course, these houses are all in the style of traditional Chinese courtyards, the short ones are only one floor, and the high ones are only three floors.

Originally, Li Kang wanted to build a tube building, but in the end, considering the aesthetics and acceptance of the Chinese people, and the main thing is that there is no shortage of land now, it is not like the old world, everyone is crowded together, and the floors are eager to be built higher than the sky.

In addition to the residential buildings, the new functional buildings are also being built in an orderly manner, at least now that the town government finally has a decent office space, the next time the meeting is held, there is no need to rub the meeting room of the government hall with shame.

In addition to Xin'an Town, the gold mine in Rongshu Town and the iron ore in Xuanyuan Town are still being excavated, especially in Xuanyuan Town, the iron-making blast furnace is being pulled up one after another, coupled with the application of coke and the optimization of the steel filling method, the steel output and quality have been steadily improved, which makes Li Kang very happy.

Because of the establishment of the No. 2 landing point in Qihuan Town, the timber transported back from the Hedong area can go directly to the town wharf.

More importantly, the first battleship had already been launched, and the sea trials were very successful, and as soon as Li Kang returned, Kaifeng couldn't wait to rush to Xin'an Town, asking Li Kang to give the warship a name, and asking him to urge the firearms manufacturing office to deliver the ship's guns as soon as possible.

This launch belongs to the 300-ton small sail Chinese warship, the average speed is 6-8 knots, the highest can rush to about 10 knots, is expected to carry 4-8 guns, in Li Kang's eyes, such a small warship is not even a torpedo boat, considering the problem of the times, it is at most classified as a frigate, and this is the first one, mainly used for testing, in fact, it is more suitable to say that it is a training ship, naturally it is not worth his racking brains to name it, so he took the name of "Xun-1" very casually.

Of course, this can't satisfy Kaifeng, in Li Kang's heart, this warship is just a training ship, but in Kaifeng's eyes, at this time, he is the flagship of the admiral of the naval division, and the tonnage of three hundred tons Li Kang naturally doesn't feel anything, Kaifeng is different, when he was still a sailor in the original world, the largest ship in the naval division is like this.

As a result, Li Kang was so perfunctory, he was so angry that he died, and then he used the rogue magic skill to stalk Li Kang to the death, and he had to let Li Kang change his name.

Li Kang is such a person, how can he be at the mercy of others, if he says that he will not change it, he will not change it, besides, it is useless to get a loud name, and it is not a three-hundred-ton boat in essence.

However, Li Kang did not embarrass the matter of naval artillery, and happily promised that he would deliver it as soon as possible, which made him turn his anger into joy and go back to Qihuan Town in a hurry.

Not to mention these construction matters, Li Kang is more concerned about the harvest of the last spring harvest and the progress of spring sowing.

When Li Kang left Xin'an Town, the harvest had just begun here, so he didn't know what the harvest would be, but he thought that similar to Fuxi Town, winter wheat was also a bumper harvest. Sure enough, the average yield per mu is nearly 200 catties, nearly 20 catties more than Fuxi Town, rape, broad beans, Chinese cabbage... The Treasury warehouse is now full.

The spring sowing also took a month, not only the original land was planted with golden rice, but also in the original hunting holy land in the eastern grasslands - now basically no animals are seen, human destructive power is awesome - tens of thousands of acres of fields for potato planting, as long as it lasts for half a year, this alone can solve the rations of most people.

May 1 of the first year of China, sunny.

Up to now, the total population of Huaxia has exceeded 20,000 people, reaching 20,471 people, and this number is still growing, because Li Kang always finds that there are not enough people, so he can only keep summoning.

With the continuous import of grain from the Hedong region, if the autumn harvest is bumper again in the second half of the year, it is foreseeable that the day when the population of China will exceed 100,000 is not far off.

Of course, the increase in population has many benefits, many projects can speed up the process, farmland can continue to expand, the output of major workshops can also be increased, and the system has unlocked several items, Li Kang's title has been successfully promoted to baron, officially ranked as a prince.

Although the last item is not really useful, no one knows it except himself.

At this time, in a workshop in Xin'an Town, Li Kang was leading a group of craftsmen around an iron pot, nervously waiting for something.

"There is still some oil, quick, add some alkali to it!" Li Kang quickly commanded.

When the people around him heard this, they did not hesitate to add alkali solution to the pot until the grease was invisible to the naked eye.

"Add soda ash powder, and then heat it again!" Li Kang said calmly, and his own subordinates did so.

"Stir!"

After half a moment, the soap was finally made, a layer of translucent solid floating on the solution, although the purity was not very ideal, but it was enough for now, at least for the Chinese people who couldn't even afford to use soaphorn before, it was undoubtedly a cleaning artifact.

Moreover, if it is so well built, how will it be updated in the future? How can it make money from Hedong people again?

"Fish it out!" Li Kang had a smile on his face that couldn't be hidden, the failure of the glass last time left him a lot of "trauma", making him a little unconfident, and this time he was finally able to make up for it.

An hour later, looking at the cuboid-shaped yellow soap that had dried in his hand, Li Kang couldn't help but feel a sense of accomplishment, "Come on! Find a dirty laundry and try it!"

The effect is naturally perfect, and the soap foam that Li Kang hated very much in the past now looks like something different.

"Have you written down all the methods?" Li Kang said to the people who had just watched together.

"It's all written down!"

"That's good, in the future, this soap will be handed over to you to be responsible, you can find more people, but the output must be enough for me!" Li Kang tirelessly instructed, "I will provide you with the raw materials on time, don't worry about this!"

"No!"
