Since Yu Jiang already thought that Zhu Yuan was from a small place, he took the trouble to explain:

"Yellow represents 60% below, and then it is orange, and the degree of mutation is 60%~90%, this kind of person may be out of control at any time and needs to be supervised. More than 90% of it is red, and if it appears, it will be immediately obliterated. ”

Yu Jiang's words shocked Zhu Yuan again. As the hero of Xicheng, he knew that Xicheng had been researching mutants like Chasi, and as far as Zhu Yuan knew, Chasi's mutation degree was around 40%.

Could it be that Yu Jiang and Yu Ling, brother and sister, are both mutants? Is this the city built by mutants?

If this is the case, all the doubts along the way can be explained. Why don't these people know about the Holy City? Because these people are outside the Holy City, it is easy to understand that they do not know the Holy City at all.

It's just that Zhu Yuan didn't expect that the technology here was much higher than that of the Holy City. Zhu Yuan dared to make 10,000 guarantees, and any holy city, including the Fifth Holy City, which was famous for its science and technology, would definitely not have this kind of high technology.

When Zhu Yuan thought about it, they had already completely passed the inspection area.

What caught Zhu Yuan's eyes was a huge underground city, with many high-rise buildings in the city, noisy cars and horses, and the prosperity was even no less than that of the holy city.

Seeing Zhu Yuan's curious and surprised look, Yu Jiang was even more sure that Zhu Yuan was from a small place, so Yu Jiang said kindly:

"Little brother, if you don't have a place to go, you might as well follow us first, and then leave after your injuries are healed."

"Thank you, Big Brother Yu." Zhu Yuan really didn't know where to go in this completely unfamiliar environment.

Seeing that Zhu Yuan agreed, Yu Jiang led Zhu Yuan'er to stop in a dilapidated block on the edge of the city.

"Arrived, this is the border area of the city. I hope the little brother will not be disgusted. Yu Jiang said slightly embarrassed.

"How could I be disgusted?" Zhu Yuan said.

However, there is still a gap in Zhu Yuan's heart, anyone who sees a bustling urban area full of high-rise buildings, and lives in such a low and dilapidated place, will have this sense of disparity.

The room is not big, the brother and sister have one room, because Zhu Yuan is injured, Yu Jiang took the initiative to give up his room to Zhu Yuan and move to the living room by himself.

"Xiaoling, you take care of Zhu Yuan, I'll go buy some food." Yu Jiang gave an order and left the room.

After Yu Ling helped Zhu Yuan to lie down in the house, the two were silent. After a long time, Yu Ling asked curiously:

"Zhu Yuan, what is your Xicheng like? I've never seen anyone outside of Smoke City. ”

Seeing Yu Ling's curious look, Zhu Yuan said:

"Our Xicheng is not as big as your Yancheng, it is a mobile city with a population of only a hundred thousand people."

"Ahh Mobile City! Obviously, Yu Ling and Zhu Yuan's focus is not in one place.

"yes." Zhu Yuan said, but he immediately realized that Yu Ling probably didn't know about Mobile City at all, so Zhu Yuan explained:

"He's a city that moves. Unlike your city, which is underground, Hectuary is on the ground, constantly moving. ”

"And a city that moves?" Yu Ling was completely interested, and excitedly pulled Zhu Yuan and didn't let go: "Tell me quickly, what is your life like there, your life there must be very good?" The sun can be seen at any time on the ground. ”

"Alas!" Zhu Yuan sighed, he thought of Xicheng, Zhou Ling'er, and those friends, and his tone suddenly lowered.

"Where is the good life? In this world, it is not easy to live. You can see the sun at any time, but you may not see the sun tomorrow at any time. Cities move to avoid danger. ”

Even if Zhu Yuan said this, Yu Ling was still full of yearning:

"But it's better than us underground. It's dark everywhere, there are only lights, no sunlight, and you can't feel the warmth of the sun at all. I don't want to live underground. In fact, like my brother, I can be a mercenary, so I can go to the ground at any time, but my brother won't let me go out with me. ”

Yu Ling pursed her lips as she spoke, looking very unhappy.

"Your brother, this is for your own good." Zhu Yuan said and stroked Yu Ling's head and comforted Yu Ling.

But immediately Zhu Yuan was shocked again!

What did he touch? A pair of rabbit ears?

Zhu Yuan's eyes passed through Yu Ling's hair, and sure enough, he saw a pair of rabbit ears.

"You ......" Zhu Yuan said in surprise, where was his hand frozen.

"Nasty." Yu Ling said, covering the rabbit ears with her hair again.

"You're real." Zhu Yuan couldn't describe his current mood. Why do good people have a pair of rabbit ears?

"Of course it's true." Yu Ling was a little embarrassed.

"How so? Aren't you human? Zhu Yuan asked a rather stupid question.

"You're not human." Yu Ling snorted, "Of course I can't compare with you, your degree of alienation is less than 30%, and my brother and I are both people who are not completely alienated, so there are some mutations in our bodies." ”

"Wait, you're saying that the people who turned yellow at the time of testing were all similar to you, and they all had mutations in some places." Zhu Yuan couldn't believe what he was thinking at this time.

Then Yu Ling nodded, proving that Zhu Yuan's guess was actually right.

"Let me figure it out." Zhu Yuan finally realized that he seemed to have made a mistake. "Are all of you mutants here? Are people with less than 30% mutation just like you? ”

"Mutants?" Yu Ling tilted her head and looked at Zhu Yuan and asked.

"Yes, people whose bodies are mutated?" Zhu Yuan said.

"Are you called mutants there? We're called the Xenoblood Warriors here. Yu Ling replied.

"What? Xenoblood warriors? How is this possible? Are you a legendary alien warrior? Zhu Yuan opened his mouth wide and his eyes widened.

"Are alien warriors rare? Except for the children, we are all alien warriors. Yu Ling couldn't understand why Zhu Yuan was so surprised?

"It's all alien warriors, including those who were green at the time of detection?" Zhu Yuan couldn't describe his current mood at all today, and he felt that he had entered a new world.

"Not really." Yu Ling said.

Zhu Yuan breathed a sigh of relief in his heart. Fortunately, it seems that those who detect that the green light is the martial arts.

As a result, Yu Ling's next sentence asked Zhu Yuan to completely shut his mouth.

"Most of those green lights are Crystal Warriors."

Another new term, Nengjing Warrior, Zhu Yuan has never heard of it at all.

Where is this smoke city? Why is there such a high level of technology? Got a legendary alien warrior? There are also Crystal Warriors who have never heard of it at all.

Is the Holy City completely unaware of this place?

"Do you have a map here? Can I borrow your map and take a look? "Zhu Yuan wants to know where Yancheng is in the Holy City area? Zhu Yuan suspected that this smoke city was in the danger zone.

"Maps? Yes! Here's the city map, here's the world map. As she spoke, Yu Ling handed the two maps to Zhu Yuan one by one.

Zhu Yuan took the map, put the city map aside, and unfolded the world map on the table, and what came into view was a very vast area. In this map, Zhu Yuan actually saw the Blue Water River.

The Yancheng where Zhu Yuan is now is really in the west of the Lanshui River.
