Having the genes of a demon king, I never intended to be a kept man.

About half an hour later, Cang Feng arrived at the meeting point.

Ye Ge had thought that Cang Feng would change his outfit for today's mission, but to her surprise, he was still wearing the same dark blue casual suit, with slicked-back hair, glasses, and his briefcase.

Nangong Qiuyue said angrily, "Teacher Cangfeng, you told us to be on time, but you were half an hour late yourself!"

"Hehe, sorry, I was a little late because I was making some preparations." Cang Feng raised his hand and straightened his suit collar again. "Alright, now that everyone is here, let's go."

"By the way, how are we going to get there?" Xia Xiyao asked curiously. "Is there any transportation? We're not going to have to drive all the way to the second line of defense, the Great Wall, are we?"

"Of course not," Cang Feng said. "The school has already prepared transportation for us."

"What is it? What is it?" Xia Xiyao asked expectantly, her eyes brimming with interest. "Is it some kind of spirit beast mount? Like, riding a dragon or something..."

Cang Feng: "...You're dreaming."

"Hmm..." Xia Xiyao paused, "So, what should we sit on?"

Cang Feng pushed up his glasses with his fingers: "We'll take the high-speed rail."

......

Twenty minutes later, Ye Ge and his group boarded the high-speed train bound for the wilderness outside the Great Wall.

The high-speed rail in this world is not much different from that in the previous world; the only difference is its appearance.

Because the wilderness beyond the Great Wall is home to many creatures of various races, including all kinds of strange beasts, magical beasts, and dark races, the train's exterior is covered with hard black metal armor. This armor is made of extremely high-strength soul steel, and the train body is also covered with hard steel spikes and cables. This is to prevent strange beasts from attacking the train. The entire train looks like an extremely long metal monster.

Similarly, the tracks of the entire high-speed rail line are also made of the same special materials, so the construction cost of each high-speed rail line outside the Great Wall is very expensive.

"Rumble rumble rumble..."

The train starts moving.

The sound of the hard metal shell rubbing against the rails could be clearly heard even when sitting inside the vehicle.

Ye Ge, Gao Shenxue, Xia Xiyao, Long Ying, Nangong Qiuyue, and Cang Feng sat facing each other in seats A1301, watching the desolate scenery rushing past the window.

The wilderness is filled with yellow sand and demonic pollution. Many plants have mutated, and occasionally, a few strange beasts or ferocious monsters can be seen wandering on the distant plains.

There were very few passengers on the Wilderness Train at first, only about a dozen people besides Night Song and his team.

However, soon after leaving the Great Wall in the mainland, more and more people boarded the train at various stations in the wilderness, and soon about 70% of the seats were occupied. This is to be expected, as there are not many high-speed rail lines in the wilderness, and this should be the safest mode of transportation for traveling in the wilderness.

The majority of the passengers were bounty hunters and witchers, along with some wilderness wanderers and adventurers. Everyone looked exhausted; their clothes were tattered, they reeked of blood, and their skin was stained with patches of black and purple, clearly indicating that life in the wilderness was extremely difficult.

"I never imagined there would be a high-speed rail line in the wilderness beyond the Great Wall."

Looking out the car window, Nangong Qiuyue couldn't help but sigh.

"Of course there is." Cang Feng picked up the thermos on the table in front of him and took a sip of tea: "Within the first line of defense, it is still considered our human territory. Why is there no high-speed rail?"

In the vast territory of all races, the human empire occupies only a tiny area.

The total area of ​​the Qin territory is approximately 100 million square kilometers. Beyond this area lies the battlefield of countless races engulfed in war.

To isolate the battlefields of the myriad races, the First Emperor of Qin built the Great Wall, a defensive line connecting all the races.

The first line of defense is the outermost Great Wall, which isolates the battlefield of all races and encloses a territory of 100 million square kilometers.

However, the outermost Great Wall is still under construction, so many creatures from all races still manage to slip through and enter human territory.

The second line of defense will encircle the 30 million square kilometers.

This section of the Great Wall still has loopholes, so various creatures can still sneak in through different means, such as those flying in the sky, those lurking underground, and those in the rivers.

The third line of defense, the Great Wall, shrank into an even smaller circle, enclosing an area of ​​nine million square kilometers, which is also known as the "inland."

This section of the Great Wall is the most perfectly constructed. During its construction, it received assistance from many other highly civilized races within the Light Faction, incorporating many cutting-edge technologies that transcend human civilization. It is designed to defend against air, land, and explosions, and is guarded by many top-tier human superhumans, making it virtually impossible for any race to intrude.

All the large city-states of the human race were built within the third line of defense, with the population in the interior accounting for about one billion.

Beyond the third line of defense, there are mostly small towns, villages, tribal groups, or underground cities. The population of the wilderness is about six billion, scattered across more than 90 million square kilometers of harsh land. Ninety percent of them are scavengers, wanderers, or adventurers.

This is the current state of human existence in this era.

Cang Feng explained these things to everyone, and then took a sip of tea.

Ye Ge was quite familiar with these historical events, as they were all included in the background story of the game "Ten Thousand Races Map," so he wasn't surprised.

Cang Feng said leisurely, "That's why we say that our Qin Dynasty's first emperor was great. In fact, the war between all races is still going on, but because there are three lines of defense, you little guys can't feel it. If it weren't for the Great Wall, I imagine we would suffer invasions from all races, large and small, every year."

"And the high-speed rail was also built during the reign of the late emperor. Without the high-speed rail, it would be very difficult for people in the interior to leave the Great Wall and go to other places."

Cang Feng sighed softly as he spoke, "What a pity... The late emperor passed away early. Of the three lines of defense, only the third line of the Great Wall was completed. The construction of the other two lines has been slowed down ever since the late emperor's death. A thousand years have passed, and the progress is still less than what was made in ten years when the late emperor was alive..."

After listening, Nangong Qiuyue suddenly understood, as if she had grasped many things at once: "So that's how it is..."

Cang Feng glanced at her suspiciously: "Your sister is the chief of the Night's Watch, and the Night's Watch's activities are mostly around the Wall. Why do you know nothing about these things?... Oh, you're not a bad student, are you? Didn't you pay attention in your first-year science and history classes?"

Nangong Qiuyue: "......"
