Whether Dr. Kane's new drug had any effect or not, Xia Feng couldn't notice it for the time being, he just felt that he was more sleepy than before.

Maybe this is a side effect of the drug, but now sleeping has become the most luxurious thing for him.

The concession agreement signed with Victoria came into effect immediately, and the boundary of the "colonial area" ceased to exist, and the whole of Yandong ushered in a complete unification.

Marenleg, the mayor of the district, came to an end, and unlike his original ambitions, the existence of the colonial district was short-lived and not glorious.

Of course, Marenleg did not feel regret and loss, nor did he complain about Xia Feng's practice, the world is impermanent, with the achievements of this half a year, he will definitely rise again after returning to China.

...

Regarding the cancellation of the colonial area, Xia Feng has no intention of asking.

Because this decision exists only on paper, and in practice, the boundaries of the colonial zone have been "dead in name" for months.

Today, Yandong is still nominally part of the Yan Kingdom, but like the canceled colonial area, it is no longer under the jurisdiction of the Ministry of Internal Affairs of Yan.

In a sense, it can be regarded as a subtle tacit understanding, the question is only how long this tacit understanding can last.

Now the initiative to maintain a tacit understanding is not in the hands of the Ministry of Internal Affairs, standing in the position of Yan Guo, of course they want this tacit understanding to continue, I am afraid, Xia Feng does not want to give this opportunity.

Looking back on this year, Yandong's resources have gone from scarcity to stability, from stability to saturation, and even today's overflow, and this development speed has far broken the record of any developing country in the world.

Of course, if it is compared with a world power with stable foundations such as Colombia or Victoria, it is still a lot worse, but at least it can be compared.

Since it can be compared, it proves that there is a possibility of catching up.

And now the biggest gap should be a mobile city that can roam freely on the land and avoid natural disasters.

....

Mobile cities are a must-have core facility for a country, because it can ensure that it can avoid a situation of "waiting for death" in the face of unknown natural disasters.

Of course, the probability of a natural disaster accurately covering the city is very small, but the small probability does not mean that there is none, once it happens, it is a devastating disaster.

Just like the airbag of a car, most old drivers may not use this function in their lifetime, but if this function is canceled because of this, you ask the drivers to do it?

Even if you don't need it for a lifetime, you have to have it, because if you don't use it, you may have to see you in the next life.

Therefore, in order to avoid the destruction of the core city that has been built with the efforts of countless people, the plan of the mobile city must be put on the agenda.

First of all, Xia Feng contacted Yuntian Group, and the reply he got from Li Yuntian was that it could be done.

In fact, Yuntian Group has participated in the construction of most mobile cities in mainland Yan, including part of the maintenance and upgrading of the main urban area of Longmen, which is also responsible for Yuntian Group.

However, it is not so easy to build a mobile city on its own.

Li Yuntian's original words are that the mobile city is the crystallization of Yuanshi technology and the crystallization of money, which is basically a "gold mountain" piled up with countless banknotes.

.....

If everything can be solved with money, it is not a problem for the current Yandong, and now, he has a huge amount of the world's three major hard currencies in his hands.

They are, money, manpower, and source stones.

The Platts brothers are responsible for the huge scale of the source stone processing plant, both the equipment and technology are top-notch, and Lao Pu has also trained a group of professionals to improve efficiency.

At present, Yandong's source stone reserves can be said to be very sufficient.

Soon, the plan of the mobile city began to be prepared, in order not to lag behind other advanced countries in the basic scientific and technological level, Xia Feng also went to find a special person, that is, the great Mel engineer.

In the past six months, Mel has provided huge technical support for the construction as the president of Yandong Academy of Sciences, which can be said to be indispensable.

But for some reason, Mel's mood has been very low lately.

....

Yandong Academy of Sciences building, inside Mel's private laboratory.

Xia Feng placed a mobile city design sketch provided by SkySky Group in front of her.

"Mel, we're going to build a mobile city, can you help?"

Mel glanced sullenly at the drawings.

"Not interested."

Seeing that her mood was wrong, Xia Feng asked in a good voice.

"What's wrong? Is there a recent invention that has failed again? ”

"Nope."

"What's going on?"

Mel lowered her head slightly, pursed her lips and muttered quietly.

"It's not the same as I said before."

"What?"

Mel turned up the volume.

"It's not the same as I said before! At the beginning, in the laboratory next door to the barbecue restaurant, you promised me that you would help me build a sky battleship after coming to Yandong, but now that Yandong has developed strong enough, what about my sky battleship? ”

Hearing Mel mention this, Xia Feng was indeed a little embarrassed.

There's no way, the two middle two diseases got together, that's what they said at the beginning, but now the plan can't catch up with the changes, and some things can't help them to be willful.

With a guilty expression, Xia Feng explained in a good voice.

"Mel, there's no way around it, we really can't put our energy into ethereal dreams at the moment."

Mel clearly couldn't accept this statement.

"How did it come true, my blueprints are perfect, do you think I'm dreaming?"

"No, that's not what I meant."

"Then why don't you help me, is it because you feel sorry for money, or do you feel sorry for the source stone?"

"It's not."

Xia Feng sighed helplessly.

"Mel, I'm sorry, I'm not worried about money and source stones, it's just that I don't want to waste time on things that can't be realized, I'm not a professional in technology, but you said it yourself at the beginning, this ship can't fly no matter what."

"I ......"

"There's no energy problem, can it?"

Mel, of course, understood that what Xia Feng said was right, she was just being willful.

But knowing this, she still pushed the drawings angrily and lost her temper.

"I said you couldn't fly, did you believe it? You're not even helping me figure it out! ”

"Sorry, I'm too busy.... I...."

"If you don't listen, don't listen, if you don't help me, I'll do my own research, and I won't help you with the problem of mobile cities, hum."

"Hey, don't ..... like that"

Mel stood up, huffing and pointing to the door of the lab.

"Get out!"

Xia Feng was very embarrassed.

"Hey, Mel, you don't need to be so angry."

"I don't care, go out and go out, I'm going to start experimenting."

Mel walked around to Xia Feng and dragged him out of the laboratory door.

Then there was a "bang" and the door slammed shut.

....

Standing outside the laboratory door, Xia Feng sighed a little disappointed.

Everyone pursues something different, and it can't be measured by other people's values, and for everyone, what they stick to in their hearts is extremely important.

Yes, he didn't help Mel, but it wasn't that he really didn't want to help, but he didn't know how.

If Mel can now insist on investing 10 billion, 50 billion, 100 billion, or 10,000 source stones, 50,000 source stones, and 10 source stones, he can make this sky battleship 100%, then he will not frown and start directly.

But the problem is that Mel is a professional herself, and she simply doesn't know that way.

Can you soar in the sky and look down on the huge ship of the earth?

If he could really create such a thing with the current Source Stone Technology, why wouldn't he want to.
