Pushing open the door, looking through the glass of the cockpit, a city looms out of the gap in the sea of clouds in the valley in the distance. It's a small city, and even if you get closer, you will feel like that. Some thick gray-black smoke was rising from the giant chimneys in the city, and the thick walls were built so high that the city was enveloped in airtightness. The crimson metal building materials look a bit like copper, and the low buildings are scattered on the cracked earth, which, combined with the surrounding desert scene, gives people a sense of loneliness and desolation.

"The border city of Tisbor, the first and last point of defense of humanity against the" dragons ". In the book, it is recorded that in order to fight against the powerful "dragon species", people gathered almost all the most advanced weapons and technologies, and after the baptism of blood and cruel tests, the final formation of such a city. ”

Tisball is the closest and only city to the "Black Dead Land", and it is also the concentration of the highest combat power of mankind, and the people who survive here are almost all cyborgs who have undergone body modification, and there are also some refugees who have survived the breath of the "dragon", so it is also said that once Tisball is breached, then the human race will be destroyed. ”

"Actually, you don't have to explain it every time." Ouya gave Oude a blank look.

"Hey, you don't understand! It's all the most advanced machinery! It's a paradise ......."

"Okay, okay, I'm almost hearing the cocoon, you better go back and tinker with your broken copper, we'll be there in about three or four hours." Ouya impatiently interrupted Oude's self-absorption, and Oude was not angry, and spread his hands and turned his head back to his small table.

Although Oude seems a little out of tune, in fact, as a mechanic, he still has a sense of mission and justice. It wasn't a task imposed on him, but every once in a while, Ode and his party would come to the border city to repair some of the military machinery and prosthetic limbs of the modified people, and also bring some things and daily necessities to the refugees.

It doesn't seem like a big deal, but it's actually a very difficult thing to do, after all, it's not easy to be physically ready to face death all the time, and to overcome the fear in your heart. I believe that he himself knows this very well, and sometimes those out-of-tune words and exaggerated expressions may also be to hide the fear in his heart.

Time passed like water, and in the blink of an eye, the sun set, and the slanting sun sprinkled the residual light on the sandy yellow ground, taking away the heat of the day.

Tisbor's at night is very different from during the day, with lights on and a noticeable increase in pedestrians, as the sound of conversation and the sound of insects breaking the silence. Finally, at the same time as night fell, we also arrived.

"Welcome, great mechanic, and may God's blessings be with you." A tall man stepped forward briskly and gave Ode a standard bow.

I don't know why, Oude was obviously stunned when he saw this person, but then reacted, and saluted: "May God's blessing be with you, hello, I am Oude." ”

"You're welcome, Mechanic, just call me Crewe, and I'll lead you the way."

"Fortunately."

Then Crewe made a gesture of please and led us inside Tisbor.

"Heck, although it's not the first time I've come, I can't help but sigh at the advanced here every time I come." Oude looked around as he spoke, the frenzy in his eyes could not be concealed.

"Hehe, although it looks a little desolate during the day, the night of Tisball is still relatively lively, because of the scorching heat, so the people here are active at night, and Tisball is the largest city of mankind after all, and it is also the strongest in science and technology, the airports here are all using the most advanced steam equipment, most of them are semi-automated, and the defense capability is quite good, your ship is stored here, unless it is a dragon attack, it is absolutely safe."

"The biggest city?" Ou Ya, who was following behind, looked curious, and quickly took a few steps forward, "But Tisball should be relatively small compared to other human cities?" ”

Oude glanced at Ouya with an idiot-like look and said, "You are still the pilot of the ship, I don't know this." The first two times we came, we were just working outside, and we didn't even get inside Tisboor. ”

"As Master Mechanic said, the Tisball you see, except for military purposes, is for outsiders and refugees who do not have entry permits, and some polluting industrial production is also carried out here, and the real city of Tisboor, you will see it in a moment."

It was not far from the straight road, and we did not have long to come to a large metal platform, about thirty square meters in size, on which there was only an upright lever in the center, and a socket with a complex shape on the lever, and nothing else. Judging from the serious expressions on the faces of the soldiers in charge of defense around them, it should be more than simple as it seems.

As for Tisball, in fact, since using this body, I have heard some rumors in other places. In the mouth of most people, Tisball is described as written in the history books, but because of the identity of the Oude mechanic, in the mouths of some relatively high-status people, Tisbal, a city with a small area on the surface, is called "the underground city that never sleeps".

"Please, sir, please give me some food!" A hoarse female voice came from a short distance away, and I turned my head to see a woman in a tattered cloth dress kneeling on the ground, holding a soldier's thigh and begging for food.

"Get out of here, this is a military restricted area, it's not for you refugees to get close to, if you don't leave, I'll shoot!" The soldier unceremoniously kicked the woman away, and raised his gun to the woman's head, and there was no trace of pity in his cold eyes.

"What's going on!" Crewe angrily walked up to the soldier and asked aloud.

"I'm sorry my lord, this woman rushed up and begged for food."

"How did you do it, how can you get the poor people to come here, and you won't have to be here next time!" Crewe cursed loudly, but the scolded soldier didn't dare to say a word, only to face Crewe with his head down.

Crewe turned her head to look at the begging woman, her cold and cruel eyes filled with disdain and disgust, and she saw that his right hand touched his waist, as if to take out something.

"Wait." Seeing this, Oude stepped forward quickly and grabbed Crewe's hand, "I think she's pitiful, so I just have some leftover food in my hand, take these and hurry up." As he spoke, Ode took out a few pieces of dry food from his waist bag, stuffed them into the woman's hand, and turned his head to give Crewe a look, Crewe seemed to understand what Ode meant, and slowly took his right hand away from his waist.

"Thank you, thank you for your great kindness." The woman glanced at Oude gratefully and quickly left the place.

"I'm so sorry, great mechanic, for your generosity to be admirable." Crewe stepped back and bowed deeply to Ode.

"It's nothing, it should be, okay, I have to trouble you to continue to guide us." Ode smiled, and then followed Crewe back to the platform.

Crewe didn't say much, only to see him take out a strangely shaped key, insert it into the socket of the operating lever and twist it slightly, and as soon as he pulled the remote lever, the ground shook in an instant, and then the entire metal platform began to sink towards the ground.

The desolate landscape of the surface changes rapidly, the sun's rays fade away, replaced by some artificial lights, and the sight is dim as far as the eye can see, only inertia tells us that we are constantly descending.

This sinking lasted for about two or three minutes, and finally, at the moment when the light re-entered her field of vision, everything reflected in Ouya's wide eyes completely shocked her.

Underneath Tisbor, there is not a huge pile of rocks piled up in the imagination, but a huge cavern, and in the middle of it is a city, a city that is several times the size of the earth's surface, and you can see how prosperous this dungeon city is from the colorful neon lights and all kinds of flying ships traveling in mid-air.

Ouya's surprise continued, and the platform beneath our feet didn't know when it had reached the ground.

"Welcome to the dungeon city of Tisball, which never sleeps, it seems that your sister is here for the first time." Crewe bowed again and smiled.

"yes, I didn't bring her here before." Oude looked at Crewe, and there was a hint of danger in his eyes, but there was no way to see it from Ouya's angle. Then he turned to Ouya and said with a smile, "This time I can also open the eyes of this little thing." ”

"Who's the little thing!" Ou Ya raised her hand angrily and punched Ou De in the back, and said angrily: "Stinky brother, you know how to bully me!" I'm going to have to help you lose weight on your wallet today! With that, Ouya walked forward quickly.

Ou De spread his hands without tears, comforted himself with his innocent lying gun, and smiled helplessly, but he didn't catch up, but let Ouya walk in front of them, because there is only one road here, and it is a VIP passage, so he is not afraid that she will be lost.

"This is a VIP passage down from the ground, and there is no way for ordinary people to enter Tisbal from here, because of your status as a mechanic, you don't have to huddle with those muddled addicts and prostitutes who smell of inferior perfumes, and I don't think you like them very much." Crewe said respectfully.

"Those people are really not very likable." Oude Road.

"Life in the city that never sleeps is full of excitement, but it is also full of filth, drugs, gang fights, illegal rehabilitation, basically every conceivable dirty thing here, because of the particularity of Tisball, so the top of the empire doesn't seem to want to meddle too much here." Crewe said.

"That's why we're now, isn't it?" After Crewe finished speaking, Ode suddenly popped out such an inexplicable sentence, and he couldn't understand its meaning at all. And Crewe didn't answer, just smiled.
