Although it was late today, Xuan Fengling's footsteps seemed to be getting more and more brisk, and the extra familiarity with the road in front of him made Li Xuan raise his eyebrows, and he didn't say anything at the moment, just followed behind him quietly, subconsciously twisted his head, looked around, and wanted to find out something, but finally dispelled this idea, after all, in this unfamiliar place, within a one-meter visual range, he couldn't detect anything abnormal.

Since Xuan Fengling is so confident, as an elder brother, it doesn't hurt for him to follow and take a look.

Along the way, the fading lights around slowly pulled down the dark curtain on the horizon. Xuan Fengling kept checking Li Xuan's location, as if he was a little worried that he was walking too fast and leaving his brother behind. Even if the road ahead is dark at the moment, the pace of the two has not slackened in the slightest.

After a short walk, the two came to an ordinary residential area, looking at the well-prepared layout in front of them, Li Xuan couldn't help but be dumbfounded, compared to the residents in the village in the situation, the houses listed on this avenue seemed to be much more scattered.

It's more like a teahouse on a desolate avenue than a house, just to attract some guests who are on the way.

But this closed door shows that idlers are not allowed to enter. It's a special flavor.

"Uncle Cai Fei! It's me! Xuan Feng Ling banged heavily on the iron fence outside the house, and he didn't seem to be worried about disturbing the people inside, or maybe this Xuan Feng Ling knew that the people inside were not resting.

Li Xuan's interest was gradually raised, and Uncle Cai Fei in Xuan Fengling's mouth had never mentioned it to himself all the way, but came to reveal the identity of the other party.

His natural way, Xuan Feng Ling, will definitely not harm himself, but what exactly is involved in this is a little intriguing.

"Squeak......

Just as Li Xuan was puzzled, the voice of an old wooden door pulled Li Xuan's thoughts back. Li Xuan pursed his lips slightly, remembering the past years in Longyin Village, when the sound of this kind of wooden door was something they were familiar with.

"Eh, it's the Wind Spirit Girl who is back!"

The person who came was about forty or fifty years old, his face was full of fatigue, and the skin and flesh on his face seemed to be about to fall off, and he drooped on his face, and with the movement of his lips, he stirred up a wave, and what was surprising was that his body was extraordinarily strong and powerful, and he walked sonorously and powerfully, and he was very strong.

Li Xuan glanced at Xuan Fengling in surprise, this girl cares very much about what she calls herself, after all, you must know that she just called her sister in passing, and she was beaten and had no power to fight back, but now how can she let the other party call her Fengling girl.

"Come in first!"

The old man naturally noticed Li Xuan on the side, nodded slightly, and pulled open the iron fence in front of him.

"Thank you!" Since she didn't know the situation, it was inconvenient to say more, looking at Xuan Fengling's eyes that dodged her slightly, with her heart, she must have come to explain it to herself in person later.

There is still a safe distance between the fence and the houses inside, and the sparse dust around it seems to indicate that it is extraordinary.

"Follow me, there are traps on both sides against the automatons." The old man answered the doubts in Li Xuan's heart in a timely manner.

This iron fence must also be the first barrier to stop the mechanical beast, so that the people inside have a chance to escape.

The simplicity of the room far exceeded Li Xuan's expectations, and the simple and simple layout was a bit like the former residence of the ghost mother-in-law, the only difference was the pile of design drawings stacked in the center of the table.

Looking at Li Xuan's puzzled look, the old man who was called Cai Fei chuckled lightly and stepped forward, without the slightest evasion.

"Oh, this is my blueprint, and as you can see, I'm extremely uncoordinated now, and I'm actually born with a disability in my legs." Cai Fei's expression was slightly helpless, and then he lifted his trouser legs.

Plain metal!

Li Xuan pursed his lips, it was indeed ordinary metal, not silver steel.

Xuan Fengling seemed to know this, and his face was full of pity.

"But I'm content to stand up here, even though my body is now tormented by the load of these legs." Cai Fei shook his head with a wry smile, "I'm relatively simple here, so you can find a place to rest by yourself, just don't be too shabby." ”

Looking at Cai Fei's departing back, Li Xuan also knew why Xuan Fengling was like this.

"Uncle Cai Fei took a lot of care of me during this trip, and he also gave me the map. I didn't know the place at all, and it was impossible for me to find you so quickly, and Uncle Cai Fei was here alone, making a living by repairing clothes and armor. ”

"How do you think I can help him?" Li Xuan cleaned up the empty bed, his silver steel body, Xuan Fengling knew, and from what he saw, Cai Fei was indeed because of the side effects of those metal legs.

Ordinary metals are not as compatible with people as silver steel. Where the bones come into contact, there will be a dull ache in the dark disease.

Cai Fei's current appearance must have been tortured by these things. But in order to survive, he had to straighten up and walk out the door.

Xuan Fengling pursed his lips and stepped forward: "Can you help him?" ”

Li Xuan took a deep look at Xuan Fengling, and the design drawings on the table were still tiled on the table, showing desolation.

Although he himself is a silver steel body, he doesn't know anything about this kind of technical operation at all, and he is not as proficient as Tang Changqing and Guo De. First of all, there is no silver steel to use here now, and even if there is, he has no ability to help the other party transfer.

"I can't help him." Li Xuan shook his head, he was telling the truth.

The reason why Xuan Fengling didn't say it at the first time must have been because he was afraid that he would refuse, so he wanted Li Xuan to see him first, and then make the most decisive decision. On the one hand, it depends on whether it is worth helping, and on the other hand, it also depends on whether he can help.

Xuan Fengling pursed her lips and stood aside, her expression was a little sluggish, although she was not qualified to blame Li Xuan, but her heart was very low, she couldn't raise a trace of interest, and she couldn't even say that it didn't matter.

Li Xuan's heart softened, and he patted Xuan Fengling's head at the moment: "Although I don't understand such a thing as bone replacement, I must have some way to relieve the other party's pain." ”

Seeing his sister so uncomfortable, Li Xuan couldn't help but feel pity, the lonely Cai Fei was like the lonely ghost mother-in-law who couldn't bear to ignore it.

Besides, the two of them have received his favor, and if they don't do something, it will be difficult to calm down.

Li Xuan took a deep breath, since his blood was curative of the stubborn diseases in the Beicang realm, it must also have an effect on Cai Fei's legs.

It's just that he is not sure whether this characteristic of his is a good thing or a bad thing for the two of them today.

Xuan Fengling finally breathed a sigh of relief, and lay back on the bed with a smile, and the day's running made him a little tired.

Li Xuan clenched his fists and leaned down by the window. whispered in his heart, even if Cai Fei has a plan, he also has the power to fight. At the moment, I also fell into a light sleep.

The night returned to its former silence, and the darkness outside the wooden door finally slowly dissipated.
