Yu'er gently helped her cover the quilt, sighed and walked out of the West House to the East House.

In the east room, Baili Frost's body has recovered seven points, but he can't walk on the ground yet.

She saw Yu'er sitting beside her sullenly, so she asked, "Girl, your face is so long, it must be because of the second girl, right?"

Yu'er nodded: "Mother, I really can't help it! If you are sick, you can still be treated." But the pulse was normal, and the operation was successful, but no symptoms could be detected. It's incomprehensible!"

"In that case, you don't have to dwell on it. As long as her life isn't in danger, you'll have plenty of time to figure it out. For Erya, it's just an episode of pain. She's strong and can get through it......"

"Well, I'll definitely cure my sister. How do you feel today?, does your back still hurt?" Yu'er asked with concern.

"It doesn't hurt anymore, but I feel a dull pain in my flesh. The muscles and bones are much better. Lying in the house every day, this old bone is a little stiff, and my heart is suffocated. ”

Yu'er smiled mysteriously: "Mother, you hold on for two more days." Two days later, my daughter will take you out for an event. ”

At this time, Nangong Yao came in with food: "Yu'er, today's lunch is a little mushy! I picked the above point, let's feed my mother-in-law first!"

Zhuang Baiyu took the soup and rice, picked up the spoon and was about to blow it cold to feed Baili Frost, when he saw this black thing, he was frightened and hurriedly said: "This, such a paste, can you still eat it? No! This rice can't be eaten, pour it out!"

So, Nangong Yao took the bowl and was about to turn around......

"Alas~—— wait!" Yu'er stopped him again: "Brother Nangong, show me the bowl." As she spoke, Yu'er snatched the bowl back again.

Nangong Yao looked at Yu'er's capriciousness strangely. I saw her pacing around the room with a bowl in one hand. His eyes were fixed on the contents of the bowl, and he fell into deep thought......

Nangong Yao didn't know why, so he didn't dare to disturb.

After a while, Yu'er said, "Brother Nangong, you are proficient in fire arts. Fire can extinguish all things, and it can also repel insects, moxibustion, and poison. You once said that the frost nail was a peerless divine weapon, forged from thousand-year-old cold iron under a thousand-year-old ice. Does that mean it's a very cold thing, and it clashes with fire?"

"Of course, as far as weapons are concerned, most of them are mainly forged by flames. But it is even more difficult to break the routine and use the Extreme Cold Technique to ice cut. That's why this frost nail is unique.

I once heard my grandfather say that the name of the person who forged this frost nail was 'Yan', and he had no surname. He has a lover who has no surname and a single name 'Zhen'.

Later generations called them "Yan Bo Zhenyi".

At first, Uncle Yan just wanted his lover Zhenyi to have an indestructible face. For this reason, he visited all over the world to seek the art of immortality. After spending a lifetime of painstaking research, she finally came to the conclusion that in order for her skin and flesh to not break, she first needs to have her bones immortal.

Although fire can extinguish evil, it can only be maintained for a short time, and once the fire is extinguished, it loses its effect. And the same is true of Ice, although it can achieve the same goal. But there will be a day when it melts.

Later, he thought of borrowing thousand-year-old cold iron and instilling thousand-year-old ice to build bones. It can not only cast its form, but also achieve its purpose. So he searched hard, and finally found the thousand-year-old ice in the extremely cold land.

If you find the thousand-year-old ice, you will naturally find the mineral deposits buried under the ice. However, unexpectedly, this thousand-year-old cold iron is even rarer, and the amount of treasure he found is too small to make a whole skeleton. So on a whim, he made a slender nail of one foot and eight inches, which penetrated into Zhenyi's bone marrow.

Later, after several lifetimes, it was somehow known. pouted the ancient tomb and brought out Zhenyi's backbone, which has been passed down to the world ever since.

In order to compete for this "frost nail", there was a lot of turmoil. Because this long nail melts when it is bloody, and it is stiff when it is bloody. So it's constantly changing in everyone's body.

It's cold, and it's spiritual. In addition to the blood that can make it warm, all metal stubborn stones, if touched it will be frosty, if touched it will be broken, it will be broken, and it is extremely powerful. Therefore, it is listed as the first of the top ten Tibetan swords.

Even though it can't be compared to our magic weapons, it is also a rare thing in the world. That's all I know about this thing......"

"I know! Thank you, Brother Nangong, your explanation has made me understand a lot, I think I have a way to save my second sister." ”

"Really?

"Hehe, the way is to adjust the blood! It was this bowl of burnt rice that made me figure it out. The reason is actually quite simple:

Water boils when it meets fire, rice becomes pulp when it meets water, pulp becomes rust when it meets iron, and rust turns into ash when it meets soil. It's like this frost nail, when it encounters a different environment, it will become a different thing.

I've always wondered why Master Wang Muxing didn't feel this pain when she planted the frost nails in my mother's body. But when it came to the second sister, the pain was unbearable, and it recurred every time I was double. The reason is that it used to be a skeleton and was hidden on top of my mother's vertebrae. Now it's going to be a different character, so it's going to have to get used to it.

Moreover, the second sister's bones and blood are peculiar, and the frost nails are in the midst of change and the heart is on fire. As long as you let it be, it will be qualitative. So in order to alleviate the pain of her seizures, I decided to refine medicine to regulate her blood.

Qi and blood originally need to be harmonized by yin and yang, and yin and yang are indispensable. If she changes her qi and blood to yin and cold simply to cater to the preferences of the frost nail, then she lacks yang heat.

So my good way is: let her separate yin and yang, as long as she can control her yin and yang blood qi, she can avoid the onset of pain. For example, if she has a double seizure, it will make her turn her qi and blood into cold. In a single time, the qi and blood are changed to yang heat. Although this method has no experience from the ancients, it is theoretically feasible......"

Baili Frost laughed when he heard this: "Hehehe, this method is very wonderful! It not only solves her pain, but also does not damage her yin and yang." This way, she can also practice the kung fu of yin and yang at the same time. ”

Nangong Yao asked, "Mother-in-law, what is the kung fu of yin and yang?"

"The world is vast, and Qimen exercises abound. However, most people have a normal physique, so they practice some basic entry, step-by-step, and from shallow to deep kung fu. However, some people are gifted, and with the help of their peculiar advantages in blood and bones, they find another way to specialize in some strange exercises, and they often achieve great success.

The skill of the Yin requires the blood of pure Yin to be practiced, while the Gong of the Yang requires the blood of pure Yang to practice. Both are extreme, and normal people cannot cultivate. So it is said by many people to be a sideshow. But how could the ghost doctor Wang Muxing not be said to be a big devil back then? and his attainments were on par with my sister's. Although there are many people killed, there are also many people saved......

I also heard that Maoshan has a yin-yang spiritualism that requires a dragon and phoenix fetus of a man and a woman. And the male protagonist has yang blood, and the female protagonist has yin blood to cultivate. This is also said to be sorcery. ”

The second sister herself is the reincarnation of Nalan Piaoxue, and her roots are the Moon Holding Dragon. Therefore, the bones and blood are peculiar, and the practice is also the skill of blood sacrifice. If I can let her better control the yin and yang blood in her body, wouldn't that be the right medicine for the case, the icing on the cake? Maybe in the future, I will be able to stand alone in the world......"

"Hehe, if she can practice Nalan Piaoxue's exercises well, she will already be famous all over the world! Although she can't talk about being alone in the world, but back then, there were no more than ten people who could talk about life and death in Nalan Piaoxue - of course, the incognito people don't know, so it doesn't count!

Because her root bone itself is a magic weapon, and it has been transformed over thousands of years, it is unique in the world, and it is definitely beyond the reach of ordinary cultivators who study and practice hard......"

"Then I'll refine the medicine tonight, and tomorrow I'll help her isolate the blood of yin and yang......"

The next day, Xian'er was outside and Nangong Yaoshen was secretly knocking and knocking, what to do...... In order to solve Wen Xiao's sporadic pain, Yu'er led the knife Meimei to adjust Wen Xiao's blood.

After a period of conditioning, Yu'er let Wen Xiao wake up: "Second sister, you listen to my arrangement, now prepare for luck." Take the yang movement first, when the qi and blood circulate, if there is severe pain in the place where the frost nail is located, it means that it is right. And then go to Yin Jing, when the Yin blood goes, the body is not painful, it is right!"

Wen Xiao followed the instructions of the eldest sister, sat cross-legged, hooked his thumb to his little finger and ring finger, and made a life handprint and placed it on his knees. Close your eyes and concentrate and let your blood flow through your body.

Walking Yang Dong first, sure enough, the pain was unbearable, she couldn't hold her limbs, and bowed forward: "Ah~!Sister, it really hurts......"

Yu'er smiled and said, "That's right, you insist on it, and then try to ...... quietly."

Wen Xiao cheered up, urged the circulation of yin blood, and suddenly felt refreshed, like a spring breeze. All the pain disappeared in an instant......

"Wow~!Eldest sister, it's much more comfortable, it's really effective!" So she kept letting the yin blood run......

Suddenly, I felt that my breath was full of dantian, and between one breath and one inhale, my mouth swallowed clouds and spitted mist, and my hair was frosty and cold.

"Eldest sister, second sister, she ?—— her frozen......" Dao Meimei felt chills all over her body next to Wen Xiao, so she asked worriedly.

"Third sister, don't worry, your second sister is fine, is this a frost nail doing the trick? It is estimated that your second sister will not be afraid of fire or extreme cold from now on. When controlling yin blood, there will be cold poison in the exercises. When controlling the yang blood, the dragon blood pill Zen clothes will make her surrounded by fire. And she is very familiar with the control of qi and blood, and my idea has really succeeded!"

After hearing this, Dao Meimei let go of her worries and said happily: "Hahaha, the eldest sister is really powerful!

"Hehe, yes! Think about it: both treasures are in her body, and she controls them easily, combining ice and fire, can she not be powerful?"

The two of them were happy, when they suddenly saw Wen Xiao stretch out his left hand and spread his palm......

'Bilibili Bilibili......'

A white light appeared in his hand, spinning rapidly in his palm. She shook her left hand and looked at it: a translucent, silver-shining cold iron dagger, covered with frost and braving the cold, appeared in her hand......

The three of them finally met the king of cold soldiers.

Take a closer look: this knife is one foot eight inches long. In the middle is the handle of the knife, and at both ends is the blade, which resembles an Emei thorn. The handle of the knife is a cylinder made of thousand-year-old cold iron, and the silver forging pattern in the shape of fish scales flashes on it, like a small flute with flowers printed on it.

The two ends of the 'flute' are knife blades, about the same width as the little finger and as thin as cicada wings. So it's sharp without cutting it. On both sides were fine ice slags, which hung like hooks and thorns on the blade. In the translucent blade, there are eight words hidden in the ice:

The left end is frozen: "Yan Ice Heart";

At the right end is frozen: "Pure Snow Blue".

Yu'er felt and said: "It seems that 'Yan Bo Zhenyi' is really a pair of people who are in love......"
