The sudden burst of light from the city immediately alarmed Huang Zhong and the others, but this light only appeared for a moment and disappeared.

In addition, the City Lord's Mansion was far away from the commercial street, so they didn't see the changes that had taken place there, but only faintly heard a voice in the distance.

Therefore, although the five of them were puzzled, they did not leave here.

After all, the lord is still in the city lord's mansion.

However, Du Yun, who was in the backyard of the inner mansion, clearly perceived the changes in the entire city in the process of touching the town monument.

One of the biggest changes is in the business district.

Just like the functional name of "commercial self-derivation", with the traction of the town monument, all the changes in his mind came to mind.

First and foremost is the Commercial Department, which is the core building of the commercial complex in Nanshan City.

A card similar to an ID card is automatically derived, and residents who live in Nanshan City need to go to the Commerce Department to register before they can obtain an identity card.

Identity cards contain all the identity information of the residents, and the currency traded is converted into merit points that can be circulated in all cities.

Merit points are issued by the Department of Commerce, and the City Lord's Mansion responds and provides corresponding work, and the citizens of Nanshan City can go to the Commerce Bureau to exchange merit points by hunting monsters and finding various materials.

Secondly, the commercial area has its own operators and service providers for stores such as clothing, food, housing and transportation, and residents can obtain the food, clothing, and other needs they want by consuming merit points.

Because the business district is a city that evolves on its own, everything runs according to the rules, and the city lord cannot break the rules of the business district at will, except for the 20% commercial tax.

In other words, even if the city lord goes to eat in the restaurant, he still needs to pay the money!

Finally, the city lord's mansion needs to recruit apprentices and arrange them to follow and learn in the major industries in the business district, and when the city is promoted to the big city and the business is completely completed, its original operators and servants will disappear.

However, Nanshan City is still a small city, let alone promoted to a big city, even if it is a middle city, there will be a long time.

Du Yun didn't take this to heart.

When it really came to that moment, it was estimated that his subordinates already had talents in this area!

"No wonder that mysterious person called these cities that fell from the sky as the Morning Star City, it turns out that the city actually has a magical means to create something out of nothing!"

"And although it was just a glimpse just now, the people who changed in those shops couldn't see any difference between them and the real ones, the real ones were incredible!"

After Du Yun withdrew his right hand from the Zhencheng Monument, he muttered with a look of amazement on his face.

The end of the world is coming, the heavens and the earth have changed greatly, under the control of an invisible hand, not to mention other places, Xia Guo alone has almost been wiped out of all scientific and technological products.

Although only two weeks have passed, there are still a large number of usable household items in the original city, and the survivors who survive can enter the city to find these items.

But once even these remaining items are consumed with the passage of time, not only Du Yun and them, but also other survivors will also face a lack of living materials.

This has always been a worry in Du Yun's heart.

However, it now seems that the mysterious people have anticipated this outcome while controlling all of this, and with the opening of cities and the self-evolution of the city's commercial districts, the survivors will not have to worry about their lives.

Then the only thing they have to do next is to constantly improve their strength and make their status higher and higher.

Survival of the fittest! Fittest!

Only the strong can get better!

Thinking of the experience from the beginning of the last days to the present, a cold light flashed in Du Yun's eyes and said: "It's just that this feeling instantly reminds me of the legendary Miao Jiang Gu Cultivation Technique, maybe we are all Gu worms in the eyes of that mysterious man, and he just wants to pick out the strongest Gu worm among them!" ”

"The only thing that is different from others is that I was lucky enough to get a mysterious system, and I became an even more powerful Gu worm from the beginning!"

"In that case, let's continue to work hard to be the strongest Gu worm!"

At this point, a momentum belonging to the city lord once again burst out from him, and his face also showed strong confidence!

Then, with a wave of his hand, Du Yun took out the small yuan stone mine placed in the system space without hesitation.

Looking at the palm-slap-sized, dragon-shaped Yuanshi Mine in his hand, his eyes swept around, and with a movement of his mind, he directly projected it towards a clearing behind the Zhencheng Monument.

Rise!

The dragon-shaped yuan stone mine flew into the air and instantly became larger, and let out a dragon groan under the shroud of rich vitality, and immediately couldn't wait to drill down.

Perhaps there is a reason for the existence of the town monument, but this time there was not much movement.

When the Yuanshi Mine touched the ground, the backyard only shook slightly, and its entire huge body instantly burrowed into the ground and disappeared.

In its place, only an arched hole with a downward slope remains.

However, as the Yuan Stone Mine was placed, strands of rich vitality suddenly escaped along the entrance of the cave, and in the blink of an eye, the ordinary level of vitality content in the backyard was suddenly nearly doubled.

And it's still going up.

After the vitality filled the entire backyard, it began to disperse towards the front yard again. In time, not to mention the City Lord's Mansion, even the vitality content of the entire Nanshan City will be greatly increased!

Du Yun took a deep breath, feeling the boiling true qi in his body, and his face suddenly showed a look of satisfaction.

If it weren't for the fact that this was not the time to cultivate, he would have been unable to resist taking one of the Birth Pills he had obtained, and then directly began to practice the "Flame Technique" and "Burning Sky Blade" here.

"The main quest has to wait, and the reward of a random deputy general draw opportunity cannot be obtained for the time being, so the next thing is to use the two deputy general draw opportunities in your hand!"

After checking his profile, Du Yun suddenly muttered to himself.

Subsequently, he directly used a random lieutenant draw opportunity.

"Ding, now start summoning a random lieutenant!"

"Ding, congratulations to the host for summoning Bocai!"

Well? Unexpectedly summoned a third-rate general?

Hearing the system prompt sound in his head, Du Yun, who was originally slightly looking forward to it, couldn't help frowning.

Bo Cai, a senior general of the Yellow Turban Army, commanded the troops of the Eastern Yellow Turban Army in the late Han Dynasty.

He had achieved certain results in the early days of the Yellow Turban Uprising, but in the Battle of Changshe, he was defeated by the army burned by Huangfu Song and fled, retreating to Yangzhai.

Du Yun also knew so much information about Bocai.

As for the rest of the matter, it is not clear to him!

"Forget it, a third-rate military general is a third-rate general, and he has led soldiers to fight, which is much better than summoning a passerby."

After comforting himself in his heart, Du Yun suddenly looked at the only time he had left to designate a deputy general to draw a chance.

"System, I'm going to use the designated lieutenant to draw a chance!"

"Ding, please decide on the name or specific information of the lieutenant!"

"Ghost genius Guo Jia!"

Listening to the system's inquiry, Du Yun's eyes burned.
