Although Ning Zengzu owed him a favor, Xiao Chen didn't make a special trip to save him, and he didn't pay attention to him during the whole process.

Even when Yan Zun threatened Ning Zengzu's life, Xiao Chen said that he didn't care about people's lives or deaths, and still made moves against Yan Zun, and it was Lei Ao who finally saved Ning Zengzu.

Therefore, if you insist on saying that this is a life-saving favor, Xiao Chen deserves it.

And he made a promise in advance and exchanged it at an equal price, now that the thing is in hand, it should be given to the Ning family, and Xiao Chen will not regret it.

After all, it's just a gesture.

"Mr. Xiao, do you really have a way to cure the cold?" Ning Zengzu wondered.

"Of course!" Xiao Chen's faint tone was full of affirmation.

"You don't have to bother Mr. Xiao about this, after a while, Qing Xuan will marry Zhuge Lin, and the cold will be solved naturally!" Ning Xuanlin said.

"Stinky boy, what are you talking about?" Ning Zengzu suddenly slapped Ning Xuanlin's head and scolded angrily, "Have you asked my opinion?"

Ning Xuan Lin Gui is the head of the family, and he is not a small person, and it is undoubtedly very shameless to be slapped on the head like this.

But he didn't dare to be angry, let alone speak, who let this man be his great-grandfather who took care of him since he was a child?

"In fact, combining with the innate divine body can indeed relieve cold disease, and it is even more beneficial to Miss Ning!" Xiao Chen said indifferently, "If you don't want me to interfere, then forget it, I can give you the same precious thing as compensation!"

"No, no, no...... Qing Xuan's cold attacks are becoming more and more frequent, solve it a day in advance, isn't it easy to solve it in advance?" Ning Zengzu said, "Let's ask Mr. Xiao to solve Qing Xuan's cold disease, right?"

"It's decided?" Xiao Chen asked.

"Well, it's decided!" Ning Zengzu nodded, and at the same time glared back at Ning Xuanlin, signaling him not to talk nonsense.

Ning Xuanlin had no choice, so he could only keep his head silent.

"Then take me to her!" Xiao Chen said.

"Xuanlin, what about the Qingxuan people?" asked Ning Zengzu.

"In the past two days, Qing Xuan's cold disease has just flareed up again, in the underground palace!" Ning Xuanlin replied.

"Seizures again?" Ning Zengzu's expression was obviously worried when he heard this, "I said why didn't she come out to greet me, this kid...... Chills are getting more and more frequent!"

"The dungeon?" Xiao Chen looked at Ning Great-Ancestor Ning Xuanlin and the others strangely.

"Yes, the underground palace was built at the request of Qing Xuan herself. Once her cold attack attacked, the pain was unbearable, and none of us could help her, and it was also worrying to watch, so she asked to build an independent underground palace in order not to worry us. When the cold attacks, she will go there for retreat and bear it alone!" Ning Zengzu sighed.

"Okay, take me to see it!" Xiao Chen said.

"Okay, follow me!"

......

Ning Zengzu and Ning Xuanlin led Xiao Chen to the entrance of the mountain palace behind the Ning family and opened the mechanism of the stone gate of the underground palace.

"Mr. Xiao, Qing Xuan is inside. You want to treat Qing Xuan, we can't bother, so we won't go in, how about you go alone?" Ning Zengzu said.

"Yes!" Xiao Chen nodded and entered the dungeon without hesitation.

When Xiao Chen's figure disappeared from sight, Ning Xuanlin finally couldn't help but say: "Great Ancestor, you are too reckless like this, although he said that he saved your life, but after all, he is an outsider, how can you rest assured that he will go in alone?"

"Xuan Lin, how did you speak?" Ning Zengzu said with a twinkle in his eyes.

"I'm telling the truth!" For the sake of his precious daughter, Ning Xuanlin rarely retorted, "Let's not talk about whether he can cure Qing Xuan, how weak and helpless Qing Xuan is at this time, you don't know, what if he enters and sees that his heart is unfavorable to Qing Xuan?"

"How could Mr. Xiao be that kind of person, not to mention, if it was really a double cultivation healing method, it would be more beneficial to Qing Xuan!" Ning Zengzu said in a shocking voice.

"What?" Ning Xuanlin almost couldn't hold back his swearing.

Thinking to himself, this old fool, are you still looking forward to letting Xiao Chen insult Qing Xuan's innocence?

How can anyone be an elder like this?

"Xuan Lin, I know you are scolding me in your heart. But there are some things that you haven't experienced personally and don't know the situation!" Ning Zengzu suddenly said with a serious expression, "What he can do is something you can never imagine. What kind of innate god body Zhuge Lin, I'm afraid it's not worth mentioning at all in front of him!"

In the Demon Cave, Xiao Chen casually took out his sword, and the powerful Yan Zun had no power to resist.

Subsequently, Xiao Chen waved his hand to freeze the entire demon cave, and he, Lei Ao, Qingyang, and Brother Liao, the four peak powerhouses had no power to resist, and they were also frozen together.

This means that Xiao Chen wants to kill the four of them, which is a matter of waving his hand.

Afterwards, although they commented that Xiao Chen was not under Zhuge Lin, it was because they could no longer find a better person to compare in the cultivation realm.

In fact, the four of them all knew very well that Xiao Chen's strength could no longer be measured by human level.

If it weren't for the drastic change in the rules of heaven and earth, he would have been able to soar a long time ago.

......

The dungeon is not luxurious, the space is not very large, and you can walk through a passage to the deepest layer.

After all, this was just Ning Qingxuan's use for retreat and cultivation alone, and it was not a big project.

The only peculiar thing is that the floor walls of the underground palace are all paved with high-grade "fire stones".

Huoyang Stone, as the name suggests, is a precious stone with fire attributes, which is mostly used by refiners to refine magic weapons.

With so many fire stones laid together, the dungeon is filled with a special heat, which can slightly relieve the cold.

But Xiao Chen knew that this was just a drop in the bucket.

Soon, Xiao Chen entered the depths of the underground palace, and saw that in the center of the space of about a few hundred square meters, a beautiful woman in a white dress was lying on the ground, her body trembling.

Ning Qingxuan's face turned purple at the moment, and her whole body seemed to be frozen, constantly bubbling with cold, which was incompatible with the atmosphere of the underground palace paved by the Huoyang stone, like two opposite extremes.

Xiao Chen walked up to Ning Qingxuan's side and squatted down to check her condition.

"Is it that serious?"

Cold sensitivity is a process that accumulates over time and progresses over time.

At first, it may not be very serious, the number of attacks is not frequent, and it is easy to overlook.

Slowly, however, the cold will become more and more severe and unbearable.

Just like Ning Qingxuan now, she was almost unconscious from the cold, and she couldn't even do her luck, so she could only lie on the ground and shiver.

Xiao Chen admired Ning Qingxuan's backbone, he could imagine this kind of heart-chilling feeling, which was not something that ordinary people could bear, but Ning Qingxuan stayed alone in this underground palace every time, afraid that his family would worry and not let people take care of him, and he had to fall into a coma several times every time to get through.

"I hope I didn't make a mistake this time, and if your performance dissatisfies me in the future, I have the right to recycle it!"

Xiao Chen said, regardless of whether Ning Qingxuan could hear it or not, he reached out and lifted Ning Qingxuan's white coat.
