The Blood Shadow Old Demon wanted to beg for mercy, but the next moment he found that he couldn't make any sound.

In the silence, the burns on his body were even more painful, and he could only grit his teeth and persevere.

Throwing the blood shadow aside, Zhang Dongyun's previously tense heartstrings finally relaxed.

Fortunately, there is this invincible city system.

But then again, although it fused the core fragments of the Immortal Trace, the game I made at the beginning had not yet been fully developed, so I passed it on.

As a half-finished game, will there be any gaps in the Invincible City system?

Will it not be possible to expand the range?

Hawkers, anyway, the lord of a city said that it is not small, and it can live a very chic life.

It's dangerous to go out of the city, so can't he just go out of the city?

Give him a mobile phone and the Internet, Zhang Chengzhu has the confidence that he can stay at home until he is old.

Fun games, good movies, and interesting novels......

Well, the world doesn't seem to have any of that.

What's more important is that there are no happy sand sculpture netizens......

Zhang Dongyun, who breathed a sigh of relief, began to think about it and became optimistic.

He made some attempts first, which were confirmed by his own memories, and most of them were in line with the settings he had made in his previous life when he was developing the game at Blue Star.

For example, if you can't bring the dead back to life, like the evil emperor Ming Tonghui, you can't resurrect it yourself, but if the living person is injured, you can treat it.

In addition to the task of system construction, things cannot be created out of thin air, but light and shadow images can be used to confuse the real with the fake.

You can teleport anywhere in the city for any distance and anywhere in the city, completely free and accurate, but you can't teleport to a place outside the city, and you can't teleport back from a place outside the city......

There are many more similar situations.

However, there are also differences from the original game setting.

For example, in the invincible city set by Zhang Dongyun in the original game, the city lord can leave a seal in the city, and if the city lord goes out and leaves the city, the seal will not be weakened.

But in the real invincible city in this world, after the city lord Zhang Da left the seal, he went out, and the seal in the city would gradually weaken.

On the other hand, in the original game setting, it was difficult for the castle lord to attack targets outside the city, and the attack would dissipate directly after it exceeded the range of the city wall.

And at the moment, this real invincible city, the city lord attacks the target outside the city, beyond the range of the city wall, and the strength will quickly decrease and weaken, but it will not dissipate immediately.

How far it can go beyond the city walls, and the detailed relationship between time, distance and power dissipation, still need to be tested several times.

While testing the function of the invincible city, Zhang Dongyun looked left and right.

The city was bare, not even a single building was there.

Well, I remember that there was a mission system when I first designed it, which was divided into two aspects: construction tasks and guardian tasks.

Completing the quest will reward construction experience points and guardian experience points respectively, and if you reach a certain standard, you can expand the scope of the invincible city.

Zhang Dongyun called up the task panel through the system in his mind.

[Random Guardian Quest 1.1 - Kill or capture the Blood Shadow Boss who enters the city]

[The city lord captures the Blood Shadow Old Demon who entered the city, completes the random guardian mission 1.1, and obtains 500 upgrade experience points]

[Elementary Construction Task 1.1 - Initialization of City Areas and Streets]

At the beginning, in order to prevent players from exploiting loopholes, Zhang Dongyun made it clear that the same invasion target could not be repeated when designing the task.

At the same time, multiple enemies are also set to enter the city together, and only one of the highest cultivation is selected as the mission goal.

Now that the system is for his own use, Zhang Dongyun has only one feeling in his heart......

Regret is very regretful!

If he could take a monster and repeat the task, City Lord Zhang would immediately brush the Blood Shadow Old Demon one hundred and eighty times now.

The construction task is even more stringent, and new tasks will only be created if the tasks are completed to a certain standard.

It is impossible to engage in a bunch of tofu scum projects, or to cheat the experience points by building goods.

Realizing this, City Lord Zhang regretted it again, especially regret......

However, at present, the first few construction tasks are considered novice benefits, and the requirements are not high.

The first construction task is to initialize the streets and urban areas, and theoretically the more reasonable the better.

But if you haven't worked in municipal planning, it's not impossible to mess around on your own.

Zhang Dongyun took what he thought was the most trouble-free way of dividing.

The road is due south, north, east and west, forming intersections, and cutting the city into four squares.

In my previous life, I went to a big city when I was in the Blue Star, with big turns, small turns, and five forks...... Just let him lose himself.

For Zhang Chengzhu, who doesn't have a good sense of direction, a simple way is more suitable for him.

The ground in the city floats brightly, and the main roads emerge and crisscross them.

Zhang Dongyun originally wanted to get eight horizontal and eight vertical, but the city is still a little small at the moment, so he can only temporarily halve it and make four horizontal and four vertical first.

In the future, when the city expands, the corresponding facilities will be changed and adjusted together.

Infrastructure such as drainage and sewage have also begun to be prepared, and in this regard, the system arrangement is quite thoughtful.

High automation, no need for the city lord to bother.

[The road planning in the city area is completed, and the city lord completes the primary construction task 1.1 and obtains 100 points of upgrade experience]

[Beginner Construction Quest 1.2 - Establishing Your City Lord's Mansion]

Zhang Dongyun stood in the center of the city and gave orders to the system.

My lord's mansion was built here.

[Please name the castle lord.] 】

According to the memory of the evil emperor, this Baiyunyuan is located in Longling, in the territory of the Eastern Tang Dynasty.

Eastern Tang ......

Zhang Dongyun thought about it, and suddenly had a bit of bad taste.

He coughed dryly: "Let's call it Daming Palace." ”

Then he looked around, and the voice was heard throughout the city:

"This city, from today onwards, is called Chang'an City. ”

The struggling Hanshan faction and the people of the Mountain Tiger Hall heard this grand voice, and their hearts were full of confusion, and their spirits seemed to suddenly have sustenance.

Looking at the golden light flashing in front of the city and the center of the city, many people felt a sense of pilgrimage in their hearts, and couldn't help but want to bow and worship.

The old demon with the blood shadow was smoking.

In great pain, he was stunned to hear the words spread throughout the city.

I thought that His Majesty would name it the Evil Imperial City, the Sun and Moon City or something......

The system completed Zhang Dongyun's order to the letter.

[The naming was successful, and the construction of the Castle Lord's Mansion began]

Golden light flashed out of thin air and landed in the center of the city.

Under the shocked gaze of the Blood Shadow Old Demon and others, a simple and majestic but majestic palace appeared out of thin air and stood tall in the city.

The three words "Daming Palace" on the plaque emitted immeasurable brilliance, and for a time it was even more dazzling than the sun.

The splendor spread throughout the city, and the walls were dyed pale gold with the light.

There are two more words on the city wall outside the square city gate.

Changan.

The Blood Shadow Demon was shocked again.

To build such a huge palace out of thin air, His Majesty had absolutely never had such means before.

Today's old man is really unfathomable.

The well-informed old devil is still like this, let alone the group of young warriors.

It was the most stubborn Senior Brother Cao, who was stunned at this time, and his heart was shocked and admired, and he almost threw himself to the ground.

[The construction of Daming Palace was successful, and the city lord completed the primary construction task 1.2 and obtained 200 points of upgrade experience]

Zhang Dongyun's ears sounded with a system prompt.

He looked at the palace in front of him and muttered to himself.

It looks bigger than the Taihe Hall in a certain palace of Lanxing in the previous life.

But in such a fantasy world, it still feels a little smaller?

[The size of your City Lord's Mansion is related to the scale of this invincible city, when you upgrade and expand the invincible city, this Daming Palace will be upgraded accordingly. 】

Zhang Dongyun nodded secretly when he heard this.

[Elementary Construction Task 1.3 - Recruit the first group of people to contain you, with a population of at least 10,000 and stable maintenance]

The system voice continues to ring.

After the two newbie welfare tasks, the difficulty of the third construction task immediately increases.

It is very pleasant to give orders and manage people, but it is difficult to manage people to eat, drink, and Lazar...... Zhang Dongyun said in his heart.

I need a deputy to help me with this kind of political affairs, I need a lot of civil servants, I need a full-time secretary......

Zhang Dongyun was having a lot of fun, and suddenly found that there was a number beating on the system interface.

This number is something he has never set in a game before.

“31535457......”

“31535456......”
