The gunfire on the battlefield gradually subsided.

With the last of the recalcitrant soldiers killed, the battle was finally over.

At this time, the sun was setting, and the demon wind was gusting around.

The soldiers began to clean the battlefield and burn the corpses, and Song Ziyu looked at the battle scene where the corpses were strewn all over the field, and his face was extremely ugly.

What is this?

A pyrrhic victory?

Although he won the battle, he paid more than the enemy.

Song Ziyu calculated in his heart and came to a result that he was unwilling to admit and had to admit:

According to this casualty and exchange ratio, the possibility of wanting to take back Yongsan ...... Very low.

With this result, Song Ziyu's heart was half cold.

I'm not reconciled.

Longshan is close at hand, but he can't go back.

It's really uncomfortable duck.

Song Ziyu looked around.

The soldiers are cleaning up the battlefield, and in addition to cleaning up the dead to prevent them from turning into zombies, collecting weapons and ammunition is a top priority.

When the enemy retreated, a number of locomotives were discarded, and these things became Song Ziyu's trophies.

Looking at these bullet-riddled locomotives, Song Ziyu's heart moved.

Calling a few pro-soldiers, Song Ziyu drove in the direction of Longshan overnight.

The enemy was completely defeated, and there was no chance to even look back in a hurry, which allowed Song Ziyu to go all the way unimpeded, and soon arrived outside Longshan City.

The first thing that catches your eye is the boundless beam potato plant!

These potatoes grow very well, they are more than two meters tall, and they seem to shade the sky in the dark night.

Song Ziyu looked very pleased.

This shows that after his departure, Longshan's career has not been interrupted, and the hope he has brought to this lifeless land continues.

As long as you have these Liang potatoes, there will be no famine in Yongsan.

Along the built canal, the locomotive soon drove through the Liangshu planting area, and a towering city appeared in front of Song Ziyu.

Let's try it soon, everyone. 】

Longshan with my heart in mind!

finally appeared in front of Song Ziyu.

Looking at the majestic city, Song Ziyu's heart was surging.

The city is both familiar and strange!

The scale of the expansion is far beyond my imagination!

What a colorful city...... In an instant, a series of people and events came to mind.

Xu Yingnan, are you okay?

……

Objectively speaking, Longshan and himself have changed in essence when they first met.

In addition to the artificial expansion, it also benefits from the access to controlled nuclear fusion energy in the shelter.

Because of the controllable nuclear fusion energy of the 013 dungeon, the entire city has been electrified.

Watch yourself create a miracle in the wasteland.

Song Ziyu had some doubts in his heart.

Mature controllable nuclear fusion technology, this is an ability that Yu Xiaguo does not master, why does it appear in Longshan?

A series of experiences gave Song Ziyu a rough estimate of where he was.

If Mira, the capital of the city-state of Mira, is on the boundary of the former southern capital, then Longshan Mountain to the southeast should be a thousand kilometers away.

Considering the vast territory of Yu Xia Kingdom, then he must still be in the homeland of Yu Xia Kingdom.

But Song Ziyu was very puzzled.

First of all, according to my own understanding, the south is the center of the circle, and within a radius of 1,000 kilometers, only in the northwest direction can there be a wasteland landform, and in the southeast direction, this kind of terrain is impossible.

Don't doubt that Song Ziyu didn't study geography well, the most prosperous place in the urbanization of Yu Xia happened to be the southeast region.

So, why do there exist in Longshan and Tuodi Wasteland?

After thinking about it, Song Ziyu could only guess one possibility, that is, the consequences of thermonuclear war.

Large-scale thermonuclear warfare has changed the geological environment and created the topography of the wasteland.

Although I can't simulate it, it's only possible.

Otherwise, this change in the landscape is unjustifiable.

But......

But this does not explain the origin of controlled nuclear fusion technology.

This technology is the greatest ambition of mankind for the future in the industrial age.

It is the key to solving the world's energy depletion.

But even the Dark Beacon Empire's mastery of controlled nuclear fusion technology is only in the experimental stage, and there is no mature technology at all, let alone applied to the capital market.

But why did I see the technology of controlled nuclear fusion in Yongsan, as well as the quite mature artificial intelligence?

Thinking of this, Song Ziyu had more doubts in his heart.

Another example is that I saw the ruins of the Nandu urban agglomeration one hundred and seventy years later in the Miluo city-state, but I didn't see these things in the wasteland.

Even a thermonuclear war should not erase the traces of human activity in the past, especially those large-scale human structures.

In addition, the annotation of the 013 dungeon indicates that there are many similar dungeon shelters, which again involves the problem of the Federation......

The more Song Ziyu thought about it, the more he found that there were so many problems that he had a headache.

……

Putting aside these distractions, Song Ziyu returns to the theme.

Longshan is right in front of you, what should you do?

Song Ziyu stopped outside the city and looked at the city for a while, and then drove the car back with a smile.

The soldiers who followed the car on the road were not as depressed as Song Ziyu.

The slaves who had followed them from the territory of Milo through the Death Zone finally got a glimpse of the great city.

They were finally convinced that Song Ziyu had not deceived them.

Zhang Song couldn't help but ask, "Boss Song, is this the promised land of freedom?" ”

Song Ziyu nodded and said, "This is my foundation." ”

"Boss Song's foundation, then we have to get it back!" Zhang Song said happily.

"Get it back!" The slave warriors were excited, and they all said that they wanted to do a great job with Song Ziyu.

But Song Ziyu's heart is not easy.

After re-evaluating the city defenses of Longshan, Song Ziyu found himself in a huge predicament.

If you want to take back Yongsan, it is best to rely on peaceful means, but for now, this is simply a dream.

The only way left is to lay down Longshan.

This is where Song Ziyu's heart aches.

Longshan was built by himself, and he didn't want to destroy or even destroy it again.

But if you don't, how can you get it back?

And......

The most tricky thing is that in order to expand Longshan, Song Ziyu personally reviewed the drawings to focus on strengthening the city defense of Longshan!

Now the city is built on its own will!

This makes him want to attack Yongsan now, relying only on the existing forces and weapons...... Song Ziyu felt a headache when he thought about it.

What is the saying?

Sitting on a crystal with a bare ass and hitting a stone with an egg.

When the city defense was built, it would have been nice to think that I would have the predicament I have today.

Unfortunately, this is all impractical.

……

It was already late at night when he returned to the Shoujiang settlement, and there was no electricity in Shoujiang, so Song Ziyu lit an oil lamp in the office, and then began to meditate.

Song Ziyu needs to think about how to recapture Longshan.

However, Song Ziyu tried everything but could not get a feasible result.

As a last resort, Song Ziyu woke up many old people in Longshan, including Su Zhen, and everyone brainstormed together to find possible solutions.

But after a night of discussion, everyone still couldn't come up with any possible solution to the problem.

In this case, some people even whimsically came up with a crooked trick to make people open the city gates with the inside and the outside.

Song Ziyu couldn't help but smile bitterly, if he didn't startle the snake, this would be a strange move, but Yu Ke, as a veteran of marching and fighting for many years, how could he give himself this opportunity?

When the day was about to dawn, Song Ziyu asked everyone to go to sleep, and walked out of the office alone to the dam in a daze.

Now that the situation has plunged me into despair, do I really have to stop there?

Longshan can't be defeated, and Shoujiang can't afford to support so many people, where should he go?

Ay!

Looking at the river flowing slowly day and night, Song Ziyu was distressed.

Water......

Suddenly, Song Ziyu thought of a solution.
