In today's spirit deficient earth, the significance of each spirit stone is extraordinary. After searching for so long, Lin Feng didn't find many spirit stones. Finally, he found such a lost spirit stone in the secret room of Tianshan sect.

However, these spirit stones can only solve the temporary needs of his cultivator. Lin Feng's practice accumulation has been very rich. Although he has only a few months, his experience and foundation have been enough to break through to the later stage of Qi practice.

The only things that can't keep up are aura and spirit stones. Without enough spirit stones, Lin Feng's cultivation is basically difficult to break through. Relying solely on the poor aura absorbed from the air, even if it is another ten or eight years, it will not be able to break through to the later stage of Qi practice.

Therefore, Lin Feng got excited when he heard Xiao nishang say that there were such spiritual stones in master Xiao's closed secret room.

"Eh! Lin Feng, this is really effective. I feel a very comfortable and cool air flow directly into the Dantian. This is a very powerful force! It is much stronger than the Qi and blood power of our martial artists. Is that what you call the vitality of the cultivator? Can you use this to cast invisibility? "

After a few moments, Xiao nishang absorbed a small piece of spirit stone held in Lin Feng's hand. Looking at the spirit stone broken into powder in front of him, Lin Feng's heart is dripping blood! Because he didn't have much, and the crazy girl in front of him was obviously a big family who ate spirit stone.

Indeed, Xiao nishang is the body of yin and Yang. There is no threshold for cultivation of special physique. Because their bodies are very pure, there is no need for further quenching, so they absorb and refine the spirit stone more quickly. The process of transforming Reiki into vitality in the Dantian was almost instantaneous. In addition, Xiao nishang had not absorbed Reiki for so long, so he sucked all the Reiki stones taken out by Lin Feng in one breath.

"Crazy girl, you have too much appetite. Do you know how precious this spirit stone is? " Lin Feng carefully collected the powder of the spirit stone. After all, there was some aura in the powder, which could be used to refine utensils or draw amulets.

When Xiao nishang saw Lin Feng's Distressed face, she said very generously, "Lin Feng, look, you're stingy. Such a small piece of jueyu hurts you like this. You're really a miser. I'll take you to Grandpa's closed secret room later. You can use the jade inside... "

"Really? Crazy girl, don't brag. Are you sure that the Jue jade in master Xiao's secret room is the spirit stone I just took out? " Lin Feng still has a little doubt. After all, the spirit stones on the earth are really scarce now. Even if there are some spirit stone mines, as long as they are exposed in the air, the spirit stone will slowly volatilize into the air and finally become ordinary jade.

"Of course it's true. I'm most familiar with jueyu's feeling. When I was born, my mother had difficulty giving birth. It was a top jade sent by my grandfather that helped my mother tide over the difficulties and let our mother and daughter live safely. "

Xiao nishang said proudly, and then began to experiment with the invisibility taught by Lin Feng.

"Lin Feng, look... I'm really invisible. Can't you see me? "

As soon as the invisibility skill was used, Xiao nishang found that his body shape had become transparent, and the whole person was excited. Only then did he understand that the cultivator and the warrior were not of the same level. She was trying to make fun of Lin Feng while she was invisible, but Lin Feng hugged her very accurately.

"Oh... Lin Feng, what's going on? I'm already invisible, aren't I? How can you see me? "

Xiao nishang struggled in Lin Feng's arms and asked.

"Crazy girl, are you four stupid? Invisibility is just a blind trick, which can deceive the naked eye of ordinary people and all devices that capture images according to visible light. But we can't escape the spiritual consciousness of the practitioners! By the way, some infrared cameras can't hide, and even some radars can clearly sweep to the invisible state. If you want to avoid these devices, you need a more complex Invisibility spell... "

Holding Xiao nishang's soft and resilient body in his arms, Lin Feng couldn't help but lower his head and kiss her.

"So it is! Well, Lin Feng, let me go. It's in my house. What if someone else sees me? " Xiao nishang couldn't hide from Lin Feng. After being pecked by him, he quickly got away.

"What are you afraid of? Aren't you invisible now?" Lin Feng hehe straight music way.

"That's not good! Lin Feng, so it seems that this stealth state doesn't have much effect. It's just that people can't see it, and they can touch it... "

After lifting the invisibility state, Xiao nishang tried several other small spells and felt very novel. But she didn't notice that the vitality in Dantian was rapidly consumed.

"Crazy girl, pay attention. Look at the vitality in your elixir field and carefully control the consumption of vitality. Otherwise, once you consume too much energy, you can't use spells. After you improve your cultivation, try these spells slowly! Now you'd better take me to your grandpa! " Lin Feng reminded.

"OK! Lin Feng, come with me. I'm afraid my grandfather doesn't know the existence of a cultivator. You say... Shall we tell him? " Xiao nishang asked again.

"Better not! Crazy girl, this is our only secret. Even to your grandfather and your father. Otherwise, don't blame me for not teaching you how to continue cultivating... "

Lin Feng is also afraid of Xiao nishang because there is a Xiao family behind her. Sometimes Xiao nishang may bargain with her because of the interests of the family.

"All right! Well... Lin Feng, I can always use the ability of the cultivator to help our Xiao family do something? " Xiao nishang said pitifully.

"It's no problem, but you should pay attention not to show your ability too much."

While walking with Xiao nishang to the courtyard of the Xiao family, Lin Feng began to scan the whole courtyard of the Xiao family with his spiritual knowledge. He was looking for the secret room where Master Xiao was closed, as Xiao nishang said. Finally, I found it under the garden in the middle of the yard. It turned out to be a secret room hidden underground. As Xiao nishang said, master Xiao's secret room was really quite good spiritual stones.
