"The sky outside the sky has finally become," He An sighed.

The voice interrupted Jia Nian's contemplation, so he subconsciously asked, "What is Outer Heaven?" ”

"Do you know the Great Wall?" asked He An.

Guo Dapang pricked up his ears at the same time and looked at He An expectantly.

"Of course I've heard of the Great Wall," Jia Nian replied.

He An's lips moved, as if he had thought of something, but the words had already been spoken, so he could only continue: "Then do you know what the main function of the Great Wall is?" ”

"Defend against the invasion of nomads in the northern steppes," Guo interjected.

He An shook his head with a smile, but did not explain.

"Isn't it?" Guo Dapang was stunned for a moment, revealing a puzzled look.

He An explained: "If it's just like that, then you are underestimating the Great Wall"

"I want to hear it in detail," Jia Nian seemed to think of something from these words.

He An sorted out his thoughts: "There are many functions of the Great Wall, but in the final analysis, there are only two points"

"First, early warning, second, take the initiative" He An said in a firm tone.

Jia Nian repeated: "Early warning and taking the initiative? ”

"Isn't it defense?" Guo Dapang interjected.

He An blurted out: "The Great Wall does not need to be defended, and the outer heavens do not need to be defended."

"This?" Jia Nian and Guo Dapang fell into shock at the same time, isn't the enchantment not used for defense? .

He An looked up at the sky: "Because as long as there is the Great Wall, the northern nomads will not dare to go deep into the Central Plains, and at the same time, they will not dare to entrench in the hinterland of the Central Plains for a long time."

"Transporting troops?" Jia Nian reacted immediately.

Then he blurted out: "Build the Great Wall in lofty mountains and dangerous places, then transport troops on top of the Great Wall, and then use the Great Wall as a basis to launch an attack at any point." If the enemy army penetrates deep into the hinterland, they only need to hold the Great Wall to raid the belly of the steppe."

"No wonder, no wonder the nomads will retreat for hundreds of miles once they are defeated, I see" Jia Nian's breathing became rapid.

Without waiting for He An to speak, he hurriedly asked: "That day, the outer heavens were the same as the Great Wall, and they had such functions?" ”

"The pagoda is like a nomadic cavalry deep into the grassland, and the outer heavens are the Great Wall of our world," He An said loudly, his heart full of pride.

This is the embodiment of the power of the state, relying only on the individual, even if he is strong, he cannot build the outer heavens.

"Hiss"

Jia Nian and Guo Dapang gasped at the same time, their hearts full of shock.

Big, really big.

A function is self-evidently revealed, intrusion and reverse incursion.

"No, how are we going to invade their copy world?" Jia Nian asked.

A smile appeared at the corner of He An's mouth: "Every Boundary City has the ability to warn and capture the world coordinates and space-time dimensions of the invasion copy, but this time it is more special, and some specimens need to be collected."

"Otherwise, why would I say that you are the blessing of our Lingjiang City," He An explained.

Jia Nian quickly asked, "How to collect specimens?" ”

"Go deep into that pagoda," He An replied.

Guo Dapang's eyes flashed with excitement: "Let's go, we'll go now"

"No" He An shook his head, and then changed his words: "Repair well, wait for the collective counterattack of the world's countries, and destroy these self-righteous invaders in one fell swoop"

"Of course, if you want to familiarize yourself with the terrain beforehand, you can also enter in advance," He An added.

Jia Nian asked casually: "The countries of the world are collectively counterattacking?" ”

"In ten days, all the nations of the world will send their armies deep into this pagoda to wipe them out completely. At the same time, it can be regarded as a great gift for our world and the outer sky" He An sighed: "The most dangerous moment has passed"

"What kind of dungeon world is this pagoda in?" Jia Nian asked as he thought of the beast cavalry and the flamingos.

It vaguely feels a bit like the games I've played before, but it feels fundamentally different.

"Maybe it's a copy of the world with a western fantasy background," He An replied.

Guo Dapang fell into deep thought: "The copy world of the Western fantasy background? ”

"Hurry up and familiarize yourself with this Boundary City, I still have something to remind you of later" He An seemed to think of something, and said to them.

Jia Nian asked: "What's the matter?"

"One month, the state only guarantees that within one month, all the patterns of the demarcated cities will remain unchanged" He An paused when he said this: "I hope you can defend this city forever and forever"

"What about a month from now?" Guo Dapang asked.

He An lowered his voice: "The law is only valid in the real world, and the heavens and the heavens belong to the junction, so the weak and the strong survive the fittest."

"So you can attack each other?" Jia Nian asked, his eyes flashing with an inexplicable light.

He An nodded: "Do it yourself, although I hope you can stand here, but I can't interfere"

"Understood," Jia Nian nodded heavily.

He suddenly felt that this was a huge pit, but he had to admit that this pit was beating willingly.

The greater the interests of the Boundary City, the greater the hatred between himself and the Yellow Dragon Guild.

A month later, after losing the maintenance of the country, the outer heavens became a place where the war spread, if you want to defend the Tiance Mansion. Then it is necessary to completely stabilize the rear in this short month.

Rear? The copy world at the end of the Eastern Han Dynasty should be regarded as a big rear.

Suddenly, a wave of realization rose, and he had a deeper understanding of He An's words just now.

Isn't it exactly the same as the Great Wall? Once the enemy invaded the Central Plains from the Great Wall. You only need to send troops to hold the Great Wall, and then you can divide your troops to raid the rear.

As for the alien cavalry in the hinterland, what awaits them is not a rich wine, but a steady stream of blades of soldiers and horses from all over the country.

Soldiers and horses all over the place? Isn't the dungeon world that real-world professionals have conquered and conquered the same as the soldiers and horses in the real world?

Thinking of this, my hands and feet were cold, and my eyes were full of horror.

Is this what the nations of the world are planning? Such a huge plan is terrifying for the whole world.

"For a month's time, you can rest assured. Next, countries around the world will join forces to make major moves, if you can seize the opportunity to gain a foothold in the outer heavens, it will not be difficult" Looking at Jia Nian with a frightened face, He An said slowly: "I believe that with the foundation of your Tiance Legion, you can seize this opportunity"

"Farewell" He An didn't want to explain in detail, so he turned around and left.

Looking at He An, who was leaving, Jia Nian fell into deep thought.

A sense of urgency rose in his heart, and he couldn't wait to build his foundations.

And the best place to build a foundation is to copy the world in the late Eastern Han Dynasty.

Only now, apparently, it's not the time.
