After the third upgrade and expansion, all dimensions of the Invincible City's space have increased fourfold.
It covers an area of 6,144 square kilometers in this world.
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 wide space outside the city.
The more it develops and expands in this way, the wider the area reserved outside the city wall will still be affected by the system.
If the enemy thinks that entering the city counts, he is totally wrong.
In this way, it is convenient to hide the true details of the scope of Invincible City.
The current scale is that 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 based on the current area of ninety-six times sixty-four.
One ring, two rings, three rings, he was very familiar with this in Blue Star in his previous life...
But now the enclosure has been successfully enclosed at the foot of the mountain, which is gratifying.
There are mountains inside and outside the mountains and between the two cities, and they still need to be leveled off.
With this in mind, Zhang Dongyun took action again and began 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 forest trees in the mountains. Zhang Dongyun just made slight adjustments and opened up large open spaces for future use.
It's just that when the people in the city saw his big move, it naturally shocked everyone.
The miraculous craftsmanship and infinite power of nature are, at this moment, in human hands.
Such a scene will naturally frighten the viewers.
Ren Yichao, the elder of the Lingxiao Sect, was outside the inner city. Looking at the shocking scene in the distance, his mind could not calm down for a long time.
He wanted to send a letter to the sect, but when he picked up the pen, his movements froze again.
What can I write?
If Chang'an is strong, can it definitely fight against the Eastern Tang Dynasty?
Or is Chang'an more powerful than Dongtang, and will become a more formidable enemy after defeating Dongtang?
Where should our own Lingxiao sect go?
Ren Yichao was troubled for a while.
As a member of the Lingxiao sect, the reason why he has always been an enemy of the Eastern Tang Dynasty is because he dissatisfied with the rule of the Eastern Tang Dynasty.
To be precise, I don't want any ruler to put pressure on me.
But now facing Chang'an City, his confidence is wavering.
Not only was Ren Yichao disturbed, but Zheng Yuan, the elder of the Zheng family, and Hu Yingjie, the elder of the Hu family, who had become prisoners, could not calm down at the moment.
After Mr. Wu Yun interrogated them, some of them were thrown into the mine, while others were sent to Longling Mountain.
The current 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 crude.
Now that a certain city lord's influence has extended to the foot of the mountain, he naturally began to consider rebuilding the road into the mountain.
It is also necessary to build roads connecting the outer city and the inner city.
Zhang Dongyun did not do it himself. Since there is currently a surplus of labor, he would leave it to these prisoners.
The influence of Invincible City has now extended beyond the mountains, so he can naturally make Hu Yingjie and others obedient, even if they don't want to work.
After these roads are repaired, it will be more convenient for the transportation of Bisong crystal mineral deposits down the mountain, and it will also help people from the mountain to go up the mountain and defect to Chang'an.
Although Hu Yingjie, Zheng Yuan and others felt extremely humiliated, they could only serve as coolies honestly at this moment.
They are certainly not professionals when it comes to building roads and bridges.
But Zhang Dongyun has never used these practitioners as engineers.
The role they play is large construction machinery...
Naturally, there are other professionals who will guide the road construction.
These humanoid construction machines come in handy to cut mountains, crack rocks, and even cut off water to build roads. The efficiency is undoubtedly much higher.
Scenes and terrains that are difficult for ordinary people to deal with are no longer a problem with these high-level practitioners.
"Boom——"
There was a loud noise and the rocks shattered.
Hu Yingjie pulled back his legs with a dark face.
Behind him, a group of Hu family disciples had sad faces, but they scrambled forward one after another, easily holding up the big rocks one by one, and then galloped through the rugged mountains as if they were walking on flat ground.
After transporting the stones to the place, they also need to regularize the shape of the stones under the guidance of professional craftsmen, and later use them to pave the road.
Hu Yingjie couldn't help but feel angry when he saw the many capable men in his clan working as coolies, but he immediately felt sad again.
He himself is the biggest coolie...
"Uncle Qi." At this time, a young man with a slightly pale face appeared next to him.
Hu Yingjie turned to look 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 came here because I want to talk to Uncle Qi about something."
"You go ahead." Hu Yingjie did not refuse, but his expression was not enthusiastic.
Hu Ming turned back and looked in the direction of the city center: "Uncle Qi, you and the other brothers and uncles should have witnessed with your own eyes that Chang'an is where the world's general trend lies."
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 its owner. Our Hu family has no friendship with the Eastern Tang royal family.
On the contrary, the royal family is still suppressing us. Since things are about to change now, I might as well take a step earlier and defect to Chang'an with my whole family."
When he heard him mention "our Hu family," Hu Yingjie's eyebrows twitched 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 that now that you are from Chang'an, you can intercede for the family? Whether everyone can survive depends on you?"
"No, I'm looking at you, Uncle Qi."
Hu Ming shook his head and said sternly: "My family won't believe what I say. Only Uncle Qi, the liaison between you and me, can convince everyone."
Hu Yingjie was silent for a while, and then spoke again after a while: "My ancestors have been in Chaohe County for generations. They have been involved in the abyss for a long time. The tree is so big and has deep roots. Even I can't persuade the family to move."
Hu Mingyan said: "It's better to be sooner rather than later. Chang'an has just been established. The earlier it comes, the easier it will be 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 gleamed: "Chen Jiezhi's boxing technique really came from Chang'an?"
Hu Ming nodded: "Not bad."
Hu Yingjie took a deep breath and was silent in thought.
“Brother Hu, it’s better to think twice before acting wisely.”
At this time, someone suddenly said: "My father saw the previous battle through his blue eyes. He will definitely not despise Chang'an again."
Hu Ming, Hu Yingjie's uncle and nephew turned around and saw a young man in brocade clothes with a sluggish look, who was saying:
"Although Chang'an is strong, it only occupies this small area at the moment. If the Hu family may make big moves, my father will definitely deal with it first."
The person who spoke was none other than Li Dan, the fourth son of the current Tang Dynasty King.
He is weak and has not recovered from serious injuries, but he was sent to work here and worked hard, but his injuries have no hope of recovery.
However, his words still focused on Hu Yingjie's hidden worries.
Chang'an is powerful. If Dongtang wants to win it, it needs to take a long-term approach.
But the Hu family is not comparable to Chang'an. If the Eastern Tang Dynasty were to attack with all its strength, the Hu family would probably be even worse than the Chen family.
After hard work in exile, even if they could make it to Chang'an, the clan members would probably suffer heavy casualties.
Saying this may be a bit derogatory to the prestige of the Eastern Tang Dynasty, but it is not unreasonable.
Hu Yingjie glanced at him, said nothing, and looked away.
Hu Mingze looked at Li Dan calmly: "Xingtian's fighting spirit is well-deserved. His Highness is so seriously injured that he still has the energy to care about the Hu family. It seems that the burden on your shoulders is not heavy enough to allow you to have such leisure."
Li Dan sighed: "Life is worse than death. The Hu family is full of heroes, so don't end up like me."
Mr. Wu Yun, projected by Zhang Dongyun, stands on the wall of the outer city of Chang'an, looking at Hu Ming and others from a distance.
Xingtian?
Is that the one with squinting eyes?
Listening to the bickering between Li Dan and Hu Ming, Zhang Dongyun couldn't help but think wildly and let his thoughts fly far away.
In the Daming Palace, he came back to his senses and couldn't help but smile.
Zhang Dongyun had one more thing in his hand.
A sky-blue orb.
It was the Blue Sky Eye brought by Li Da, Fang Wu and others.
Li Dan thought that the king of Tang Dynasty in the distance could see clearly what happened in the previous battle through this treasure, but he thought too much.
When Invincible City upgraded and expanded for the third time and included them all, Zhang Dongyun discovered that Fang Wu had this treasure in his hand.
Moving mountains and seas is indeed powerful, but he doesn't want to scare the enemy away from coming.
So as soon as he noticed the Blue Sky Eye, Zhang Dongyun blocked the function of this treasure.
The king of Tang Dynasty in the distance could only see that the scene presented by the orb suddenly turned dark.
As for the reason, he could slowly guess it himself.
It's not as scary as moving mountains in the air.
However, when this orb came into Zhang Dongyun's hands, it gave him some ideas.
Maybe he can use the treasure, but it needs to be improved.
However, 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.
Is there someone who might be suitable?
It just so happens that there is something really important that needs to be addressed to her... Zhang Dongyun thought to himself.
Soon, a ten-year-old girl appeared in the hall.
It was Shen Herong.
Her current pseudonym is Ming Yixue, and she is one of the servants of the Lord of Chang'an City. Normally, she lives in the Daming Palace. From time to time, she transforms into a young scholar and goes to the city academy to teach.
When the girl entered the main hall and saw that there was no one else in the hall, all the childishness on her face disappeared, leaving only a mature and calm look that was inconsistent with her age.
Seeing Zhang Dongyun who looked like Ming Tonghui above, playing with a sky-blue orb in his hand, she couldn't help but smile: "Brother, do you also play with this?"
"Remember you once had a pair."
Zhang Dongyun raised his hand casually, and his blue eyes flew to Shen Herong.
Shen Herong smiled and caught it: "It was decades ago, but now there is no trace."
"I came to you because of a piece of news."
Zhang Dongyun is sitting with his hands folded in front of him, with his ring finger and little finger interlocked, and the tips of his middle finger, index finger and thumb facing each other.
"Wu Yun interrogated the prisoners and came out with a piece of news. There are people from the Demonic Way who are causing trouble in Yechuan County, about 4,300 miles south of here."
He looked at Shen Herong and said slowly: "It is said that it is the transformation of the mountain-moving demon ape."
"Mountain-Moving Demonic Ape..."
The smile on Shen Herong's face disappeared and her expression became serious.
She naturally knew why her eldest brother specifically mentioned this matter.
Among the sworn brothers and sisters of the Twelve Yamas in the past, there was one person who was related to this.
The eldest brother’s eleventh brother, her eleventh brother.
"Ape Dragon King" Ao Kong.
In the past, a powerful man in the demonic realm had the dual transformations of a mountain-moving demon ape and a phantom dragon, which was rare in the world.
