I Have An Impenetrable Fortress

After the third upgrade and expansion, the size of all aspects of the Invincible City's space, the third change, all increased by four times.

The area covered in this world reaches 6,144 square kilometers.

Of course, this is the current scope of influence of the system. Because of Zhang Dongyun's operation, the scale of the city wall enclosure is not that large, leaving a vast space outside the city.

The more it develops and expands like this, and the area outside the city wall is reserved, the larger the area still affected by the system will be.

If the enemy thinks that entering the city counts, it is a big mistake.

In this way, it is convenient to hide the real details of the invincible city.

The current scale, the inner city covers an area of ​​24 square kilometers, and the outer city covers an area of ​​384 square kilometers.

After the next expansion, Zhang Dongyun will build a third city wall on the basis of the current area of ​​ninety-six times sixty-four.

First ring, second ring, third ring, he was very familiar with this in Blue Star in his previous life...

But now the enclosure has successfully reached the foot of the mountain, which is gratifying.

There are mountains between the two cities inside and outside the mountains, and they still need to be leveled.

With this in mind, Zhang Dongyun started to tidy up the mountains and forests between the outer city and the inner city.

There is no need to clear all the peaks and forests in the mountains. Zhang Dongyun just made some adjustments and opened up a large area of ​​open space for future use.

It's just that his big move fell into the eyes of the people in the city, and it naturally shocked everyone's attention.

The uncanny workmanship and infinite power of nature are in the hands of people at this moment.

Such a scene naturally makes the viewers terrified.

Ren Chao, the elder of the Lingxiao Sect, was outside the inner city, looking at the earth-shattering scene in the distance, unable to calm down for a long time.

He wanted to send a letter to Zongmen, but when he picked up the pen, his movements froze again.

What can I write?

Chang'an is strong, will it be able to fight against Dongtang?

Or is Chang'an stronger than Dongtang, after defeating Dongtang,

Will it be a more terrifying enemy?

What should my Lingxiao faction do?

Ren Chao was tangled in his heart for a moment.

As a member of the Lingxiao faction, the reason why he has always been an enemy of the Eastern Tang Dynasty is because he refused to accept the rule of the Eastern Tang Dynasty.

To be precise, I don't want any ruler to be on my head.

But now facing Chang'an City, his confidence is shaking.

Not only was Ren Chao restless, but the old Zheng Yuan of the Zheng family and the old Hu Yingjie of the Hu family who had become captives could not calm down at this moment.

After Mr. Wu Yun interrogated them, some of them were thrown into the mine, while others were sent to Longling Mountain.

The immediate task of Hu Yingjie, Zheng Yuan and others is to build roads.

The roads built by the Tang army when they went up the mountain were very rough and simple.

Now that the power of a certain city lord has extended to the foot of the mountain, he naturally began to think about repairing the road into the mountain.

It is also necessary to build roads connecting the outer city and the inner city.

Zhang Dongyun didn't do it himself, since there is a surplus of labor right now, let's hand it over to these captives.

The scope of Invincible City's influence has now extended beyond the mountain, so he can naturally make Hu Yingjie and others obedient, even if they don't want to work.

The repair of these roads will be more conducive to the transportation of the bisong stone crystal minerals on the mountain down the mountain, and it will also facilitate the people from the mountain to go up the mountain and go to Chang'an.

Although Hu Yingjie, Zheng Yuan and others felt extremely humiliated, they could only act as coolies honestly at the moment.

They are certainly not professionals in building roads and bridges.

But Zhang Dongyun never used these practitioners as engineers.

The roles they play are large construction machinery...

The professionals who guide road construction are naturally different.

With these humanoid construction machinery coming in handy, the efficiency is undoubtedly much higher for breaking mountains and cracking rocks, and even cutting off water to build roads.

Scenes and terrains that are difficult for ordinary people to handle will not be a problem with these high-level practitioners.

"Boom—"

With a loud bang, the rock shattered.

Hu Yingjie's face darkened, and he withdrew his legs.

Behind them, a group of Hu family children were frowning, but they rushed forward one after another, lifted up the big rocks one by one, and then galloped across the rugged mountains like walking on flat ground.

After transporting the stones to the place, under the guidance of professional craftsmen, they have to shape the stones into a regular shape and use them to pave the road later.

Hu Yingjie looked at the many able-bodied children in the clan, all of whom were working as coolies, and couldn't help feeling angry, but immediately felt sad.

He himself is the biggest coolie...

"Uncle Seven." At this moment, a young man with a slightly pale complexion appeared beside him.

Hu Yingjie turned his head and glanced at Hu Ming, took a deep breath, and tried to be as calm as possible: "Are you the supervisor?"

Hu Ming shook his head: "I'm here because I want to talk to Uncle Qi about something."

"Go ahead." Hu Yingjie didn't refuse, but his demeanor wasn't enthusiastic either.

Hu Ming turned his head and looked in the direction of the center of the city: "Seventh Uncle, you and other brothers and uncles should have witnessed it with your own eyes. Chang'an is the general trend of the world."

Hu Yingjie didn't make a sound, just listened quietly.

Hu Ming continued: "We can all see that the Eastern Tang Dynasty is about to change owners, and our Hu family has no friendship with the Eastern Tang royal family.

On the contrary, the royal family is still suppressing us. Since the weather is about to change now, I might as well wait one step earlier and go to Chang'an with the whole family. "

When he heard him mention "our Hu family", Hu Yingjie's eyebrows trembled slightly, but he did not interrupt.

It wasn't until Hu Ming finished speaking that he looked at the other party playfully: "You want to say, you are now a native of Chang'an, and you are just interceding for the family? Whether everyone can survive depends on you?"

"No, it's about you, Uncle Qi."

Hu Ming shook his head, and said seriously: "The family members will not believe what I say, only Uncle Qi can make contact with you to convince everyone."

Hu Yingjie was silent for a while, and spoke again after a while: "My ancestors have been in Chaohe County for generations, and they have long been implicated in the abyss, and the tree has deep roots. Even if I am, it is difficult to persuade the family to move."

Hu Ming said: "It should be sooner rather than later. The sooner Chang'an is established, the easier it is to take root. The Chen family is already one step ahead of everyone. Uncle Qi has also seen brother Jie's boxing skills."

Thinking of Chen Jiezhi's Dragon Slaying Fist, Hu Yingjie's eyes froze: "Chen Jiezhi's boxing technique really came from Chang'an?"

Hu Ming nodded: "Not bad."

Hu Yingjie took a deep breath and remained silent in thought.

"Brother Hu, it's better to think twice before acting."

At this time, someone suddenly said: "In the previous battle, the father saw everything through Qingtian eyes. He will definitely not despise Chang'an again."

Hu Ming, Hu Yingjie's uncle and nephew turned their heads to look, and saw a young man in brocade clothes with a sluggish expression, and said:

"Although Chang'an is strong, it only occupies this corner of the land right now. The Hu family may make a big move, and the father will definitely give priority to it."

The speaker is none other than Li Dang, the fourth son of the Tang King.

His breath was weak, and he was seriously injured, but he was also sent here to work, and he worked hard to persevere, and there was no hope of recovery from his injuries.

However, in his words, he still focused on Hu Yingjie's hidden worries.

Chang'an is powerful, and if Dongtang wants to win it, he needs to make a long-term plan.

But the Hu family can't compare to Chang'an. If Dong Tang goes all out to attack, the Hu family may be even worse than the Chen family.

After working hard in exile, even if they could reach Chang'an, the clansmen would suffer heavy casualties.

Saying this may be somewhat demeaning of the Eastern Tang Dynasty's own prestige, but it is not unreasonable.

Hu Yingjie glanced at him, did not speak, and looked away.

Hu Ming looked at Li Dang calmly: "Xing Tian's fighting spirit is well-deserved. His Highness is seriously injured, and he still has the energy to care about the Hu family. It seems that the burden on your shoulders is not heavy enough for you to have this kind of leisure."

Li Dang sighed: "Life is better than death, the Hu family is full of heroes, don't fall into my situation."

Mr. Wu Yun, projected by Zhang Dongyun, stood on the wall of the outer city of Chang'an, looking at Hu Ming and others from a distance.

Xing Tian?

Is that the squinting eye?

Listening to Li Dang and Hu Ming arguing, Zhang Dongyun couldn't help thinking divergently, and his thoughts flew far away.

In the Daming Palace, he came back to his senses and couldn't help smiling.

There was one more thing in Zhang Dongyun's hand.

An azure orb.

It was the blue sky eyes brought by Li Dang, Fang Wu and others.

Li Dang thought that the Tang king in the distance could see clearly the previous battle through this treasure, but he was thinking too much.

When Invincible City was upgraded and expanded for the third time, when they were all framed in, Zhang Dongyun discovered that Fang Wu had this treasure in his hand.

Moving mountains and seas is indeed mighty, but he doesn't want to scare the enemy from coming.

So Zhang Dongyun blocked the function of this treasure the first time he noticed Qingtian Eye.

The king of Tang in the distance could only see that the scene presented by the orb suddenly went dark.

As for the reason, he slowly guessed by himself.

It's not as scary as moving mountains in the air.

However, this orb was in Zhang Dongyun's hands, which gave him some ideas.

Treasure, maybe he can also use it, but it needs to be improved.

It's just that if you use the power of the invincible city to transform it, it will gradually dissipate after leaving the city, so you have to find another way.

Someone, maybe just right?

Coincidentally, there is another really important matter, and I want to find her... Zhang Dongyun thought.

Soon, a ten-year-old girl appeared in the hall.

It was Shen Herong.

She is currently aliased as Ming Yixue, and she is one of the servants of the Lord of Chang'an. Normally, she lives in Daming Palace. On weekdays, she takes the form of a young scholar from time to time and goes to the academy to teach in the city.

When the girl entered the main hall, seeing that there was no one else in the hall, all the childishness on her face disappeared, leaving only a mature and calm that did not match her age.

Seeing Zhang Dongyun, who looked like Ming Tonghui above, playing with an azure orb in his hand, she couldn't help smiling: "Brother also plays with this?"

"Remember you once had a pair."

Zhang Dongyun raised his hand casually, and Qingtianyan flew in front of Shen Herong.

Shen Herong smiled and caught it: "It was decades ago, but now it's gone."

"I came to you because of a message."

Zhang Dongyun is sitting, with his hands folded in front of him, the ring finger and little finger intertwined, and the middle finger, index finger, and thumb facing each other.

"Wu Yun interrogated the captives and found out a piece of news that there are demons making trouble in Yechuan County, which is about 4,300 miles south."

He looked at Shen Herong, and said slowly: "It is said that it is the transformation of practicing the mountain-moving magic ape."

"Mountain-Moving Demon Ape..."

The smile on Shen Herong's face disappeared, and his expression became solemn.

She naturally knew why her elder brother specifically mentioned this matter.

In the past, among the twelve brothers and sisters married by Yan Luo, there was one who was related to this.

The elder brother's eleventh brother, her eleventh brother.

"Ape Dragon King" Ao Kong.

In the past, a powerful man in the way of demons, who simultaneously possessed the double transformation of the mountain-moving demon ape and the magic dragon, was rare in the world and looked down upon.
