In doing so, Han Feng can not only strategically connect Sand Wolf City and Wangcheng on railroad tracks, but also strengthen the connection between the two places, which can stabilize the principality and make Wangcheng not prone to chaos.

After all, once there is chaos in the royal city, Han Feng's army can arrive by train at any time, and there will be no chance for anyone to be chaotic at all.

The second is that such a huge project has given the people who are already struggling to make a living a chance to recuperate. As long as you are willing to work, you will make money. With money, no one will be on the streets and doing evil. This has played an extremely beneficial role in the appearance of the entire royal city.

The damaged trade of the royal city was soon restored.

Because there are so many people, they have to eat when they go to work. Merchants and caravans saw business opportunities, and a steady stream of caravans brought grain to sell in the royal city.

And the people of Wangcheng, who work with Han Feng and earn money, have money to buy food to eat, and the merchants' grain can be sold, and the people who have food to eat will not be hungry, they will have a sense of happiness, and the sense of national identity will be strengthened.

Then the country will definitely stabilize all of a sudden.

The four words of rest and recuperation were really taken to the extreme by Han Feng.

As an archon, Han Feng's greatest credit is that he does not issue decrees easily.

Let the country take a breather first.

A month passed like this.

During this time, in addition to connecting the railway from Sand Wolf City to Wangcheng, Han Feng also tinkered with the engine at home.

There is light oil from the Blackwater Swamp.

This light oil does not need to be refined and can be used directly. This kind of oil field, in the earth world, Han Feng just knows that it exists. Of course, Huaxia did not. Yes Africa has.

Unlike heavy oil, it still needs to be refined.

Then, with this kind of light oil that does not need to be refined, it is possible to develop fuel engines.

On this day, outside Sand Wolf City, on a flat sandy ground that has been tamped by artificiality, something strange in the eyes of the people of Sand Wolf City is stopping there.

Before the experiment began, the people of Sand Wolf City heard about it, and it seemed that this guy made of wood would fly next.

Something that doesn't have wings can fly, why don't the people of Sand Wolf City believe it.

Although it is already known that there is something called a kite, which can fly.

However, that's not the same.

The kite is made of bark paper, it is very light, and it does not need to carry people, it can fly on its own, then it can fly.

However, now the guy that Han Feng wants to test is such a big guy made of wood, and there are a lot of things on it, and he will have to go up and drive it later, so who would dare to believe that such a thing can fly.

It's time for a test flight.

Han Feng is coming, and Han Feng's daughters-in-law are here. It's just that Han Feng's daughters-in-law are a large group of people, and they seem to be mighty. Let the men of Sand Wolf City really envy Han Feng alone to enjoy so many beautiful women.

To test fly, Han Feng didn't say much nonsense, because of self-confidence.

came, Han Feng just boarded the plane and made people pluck the propellers of the plane.

A warrior with the power of the Divine Blessing Stone can easily start the aircraft engine in one fell swoop.

Black smoke came out of the starting car.

Han Feng's ordinary face of the pusher, afterburner, propeller of the single-engine two-seat wooden plane, is easy to glide on the tamped flat runway.

Fly?

Fly?

Everyone is nervous and excited.

Especially Hai Weier, who has enjoyed the night with Han Feng at night, seen the stars, and talked about the universe and rockets, is the most looking forward to and excited, and the dream of all these technologies that Han Feng told her may soon come true.

Therefore, among these people, she and her maid Nancy were the most excited.

Fly?

Fly?

Hevelle was nervously looking forward to the plane, which could really soar into the sky like a bird.

Just when she was so nervously looking forward to it, Han Feng's plane suddenly soared into the sky, rose from the ground, took off, flipped over, soared, and all in one go!

Simply perfect take-off!

Han Feng's plane flew together, and immediately pulled over the nose of the plane, and then did a flip and maneuver, and flew over the heads of all the onlookers who were present today, and directly went to fly over the city of Sand Wolf City.

Han Feng is the first time to view the Wolf family from the sky, check out Sand Wolf City, check out his home!

That kind of mood is extremely exciting.

It's not Han Feng, it's hard to experience.

"Fly, fly, really fly! Sister Vivian, Sister Nala! The plane that the husband said could fly, really flew!"

provoked Vivian to comfort her with pity for Han Feng.

Fly, really fly!

Vivien never doubted that what Han Feng said would not be done.

In her eyes, as long as it is something that Han Feng has said, she will definitely do it.

It's like this moment.

It's also like the trebuchet fighting sand thieves in the past, the artillery hitting Wanshan City, and the train that can run and pull 10,000 tons of goods, which thing, Han Feng said, but he didn't do it?

No, not at all!

There is nothing that Han Feng said that he can't do.

However, even so, Vivian was so excited for Han Feng.

Han Feng flew in a circle in the sky and soon landed.

Because Han Feng has more important things to do.

He wanted to take these daughters-in-law and each one of them to heaven to see.

Just when Han Feng was thinking so excitedly, he just ran in front of Vivian, and before he could say this, Vivian suddenly stretched out her slender hand to cover her mouth, ran to the side and vomited.

Han Feng was stunned for a moment, and then chased after Vivian excitedly. Obviously, Han Feng knew what happened to Vivian.

Immediately afterwards, Nala, who saw Vivien running to vomit, suddenly couldn't help but run to the edge of the runway and vomited.

Han Feng was happy around Vivian, and when he saw that Nala was vomiting here, he immediately became even more surprised that he couldn't take care of it.

When they all vomited, Han Feng immediately pulled the two daughters-in-law together, took their hands together and said, "You have it, do you know?"

The two women didn't know it, but now they both know and nodded shyly.

"The bad days are indeed not coming. I thought it was too late again. Nala said embarrassedly.

Hearing Nala say this, Han Feng couldn't help but blame her: "Vivian is young and doesn't know, it's normal. You're a big girl, why don't you even know you have it. ”

While blaming the big foolish girl's negligence, Han Feng took the pulse of the two daughters-in-law, and Han Feng took the pulse, which was clear at once.

"It's been more than a month, and you all have it together, it seems that it was last time, and the two of you accompanied me together and conceived together. Haha, you men and I, it's really amazing, a double color!"
