Yunfan with white keel came to the hall on the second floor, sat down on the sofa, a dignified face.

It's just a white keel. The storage capacity of aura on it is enough to compare with half of the spirit sand in the night bar. It's very majestic.

If it wasn't for the fact that it could replace herbs to help Fang Ling and Su Su practice, he would almost like to refine it.

After thinking about it, he took out his mobile phone and made a call to Mr. Jiang. The call was soon connected.

Jiang's voice came from the phone, "master Yunxian, can the white dragon bone still satisfy you?"

Yunfan: "very satisfied, thank you."

"You're welcome. Compared with your kindness, a mere white keel is nothing. Thanks for your blessing. Now my stubborn illness is gone. It's like I'm a few decades younger. I feel I've improved a lot in martial arts these days. I thought I couldn't survive for a few more years at most. Now it seems that I can't survive for 20 or 30 years. " Jiang's tone was sincere and full of gratitude.

Yunfan did not exchange greetings with Mr. Jiang. He asked directly, "I want to ask you, where did you get this white keel?"

Mr. Jiang: "I bought it from my friend. Do you still want this kind of white dragon bone?"

Yunfan: "yes."

"I'll ask my friend to help you look for it. He has only this white keel in his hand. I can't find too many for a while," he said

"No, I don't want you to look for it. I want to know the origin of this white keel." Yunfan has long seen that the white keel he got is different from the ordinary bone fossil. It has a lot of aura. In fact, it has another name in Xiuxian continent, called Linggu.

Spirit bone is usually the product of gathering spirit formation.

It was discovered in the ancient battlefield of Xiuxian continent in the early period.

At that time, the ancient battlefield was full of skeletons, but the skeletons in a mile area were all spiritual bones. After being discovered by the immortal practitioners, there was a big storm. Many forces swarmed into the ancient battlefield to snatch spiritual bones, with more than ten thousand deaths and injuries.

Later, many immortals made full efforts to explore and found that there was a spirit gathering formation that had stopped working in that place. They just learned that the spirit bones were bred in the spirit gathering formation after thousands of years.

Although the white dragon bone obtained by Yun fan can also be called the spirit bone, it can't be compared with the spirit bone of Xiuxian continent. The spirit concentration of the former is much lower than that of the latter. However, it's a rare thing to have the spirit bone of white dragon bone in this late Dharma era.

Yunfan wants to know the origin of the white keel. Naturally, he wants to know whether it is made by human beings or bred by nature.

If it is made artificially, the number may be very small.

However, if it is bred by nature, there will probably be a lot of spiritual bones in the world. If he can find the breeding place, he may not be able to find more spiritual bones.

Jianglao's voice became a little worried, "the origin of this white keel, my friend also took it from the antique market. If it hadn't been well preserved, it would not have been sold. After all, it's too unpopular. It may be very difficult to find its real origin."

Yunfan didn't expect that the white keel would be bought in the antique market. It's very difficult to trace its origin, but he said: "you try your best to ask for it. You don't tell me until you trace back to its original origin. Of course, if you can't, there's no way. I can understand it."

Jiang: "OK, I'll try my best to find its original source."

"Let's say that first. Hang up."

Yunfan hang up the phone, the heart of the white keel to find the source or a bit of expectations.

After thinking about it, he sacrificed Bingling.

The ice silk, like a silver bracelet, drifted out of his wrist and turned into a silver thread floating in front of him.

The two ends of the silver thread stretched out, and the whole silver thread was quickly pulled to the length of half an arm. A scene of ice flakes broke out of the wall of the silver thread.

Yunfan put the white dragon bone on the ice, and the ice immediately spread and grew into a rectangular ice box, trapping the white dragon bone in it.

Countless ice blades flew out of the six ice walls of the ice box. In a moment, the white dragon bone turned into a pile of gray powder.

The ice box shrinks and deforms, and finally turns into a silver thread with a diameter of one centimeter. It is wrapped around Yunfan's wrist three times. It looks like a strange silver bracelet, in which the powder of white keel is wrapped.

After dinner, Yun fan takes Fang Ling and Su Su to the master bedroom on the third floor, and also takes the white suitcase.

The layout of the third floor is the same as that of the second floor. The bathroom of the master bedroom is still separated by sandblasted glass at one end of the room.

Yunfan comes to the bathtub in the bathroom and puts hot water on it.

Under his control, one end of the ice silk opened a hole and dropped some white keel powder into the water. The aura of the whole bathroom immediately became very strong.

Yun fan came to Fang Ling and Su Su and said, "today you can practice together. Anyway, you don't have to worry about one more person."

The bathtubs in the master bedroom of his villa are all round, so it's nothing to lie down.

Su Su thought Fang Ling would mind, but she said without thinking, "OK."

"Well." Yun fan nodded and continued: "today's practice will be a little changed. Maybe you will feel like ordinary water when you look at the water in the bathtub, but in fact it is very different from ordinary water. The water in the bathtub contains rich aura, which is far better than the previous medicine pool. "

Fang Ling nodded, but when she thought about it carefully, she was surprised and asked: "if the effect is better, it won't be as painful as the last time it was made for the first time, will it?"

Yunfan was so dumb that he couldn't laugh. No wonder Fang Ling asked such a question. The last time he helped her to strengthen her body for the first time, she broke her throat, couldn't stand it, and almost did something stupid. But at that time, he was so eager to succeed that she even went to the wine bar to practice afterwards.

When Su Su first strengthened her constitution, she didn't suffer the pain of Fang Ling, but she was also very embarrassed.

Hearing Fang Ling's words, Su Su was a little worried. If this time's physical strengthening would be like the first time, she could not imagine how embarrassing it would be for her.

"No, Lingqi is much softer than ordinary herbs." Yun fan shook his head. If it wasn't for their poor foundation, he even wanted them to drink the spirit water made of white keel directly. Only in that way, he would have to stay by their side every day to help them refine. It was a waste of time for him. After all, he wanted to cultivate himself.

After a speech, Yun fan continued: "so today, I will teach you a new method of cultivation, which will no longer be one-sided physical strengthening, but your own cultivation. In other words, to obtain this method of cultivation, for you, is equivalent to obtaining the entry volume on my road of no return. "
