is also said, Yunfeng is poor now, there is nothing, there is really nothing good. Not to mention the spine that is used as a space......

"Boy, I think you are now using the pill as the base of the formation and the space boundary stone as the formation eye, which is more practical. Your dantian is the five elements, and you can use the five kinds of pills you have in your hand, such as the Determined Wuji Pill, the Five Wood Shengxiang Pill, the Qianyu Jiyun Pill, and the Seven Fire Peili Dan, to feed the formation base and build a space for the balance of the five elements. This will also help you in your future cultivation, and at the same time, you will be able to collect more resources......"

Oh my God, just these five kinds of pills, they are all super second-level good pills, if Yun Feng takes them out and buys them, he can buy them at a good price casually. It's just a temporary substitute here, so you can imagine how much it takes to build a space......

"Now, take out the Space Boundary Stone, use your Divine Soul to communicate with it, and incorporate it into your body, as for where you want to put it, it's up to you to decide, my suggestion is where you put it in your stomach. This location is special, it is in the middle of the heart, liver, lungs, spleen and kidneys, and does not belong to the five organs, because the five organs are closely related. The five internal organs represent the five elements, so that you can also achieve a relative balance......"

Yun Feng didn't say a word, and took out the Space Boundary Stone from the storage ring. Today's Space Boundary Stone, after being nourished by Yun Feng's heart and blood, has become red, and it is still shining with a little starlight. At the same time, there seems to be an infinite attraction that is constantly absorbing the aura around it, like a bottomless pit that cannot be filled. Yun Feng tried to feed it a lot of Pei Yuan stones, but he didn't seem to be full, but the more he ate, the more hungry he became, which directly frightened Yun Feng......

Yun Feng held the Spatial Boundary Stone in his hand, and constantly tried to enter it with his soul power, but no matter how he tried it, he couldn't ......

"The Space Boundary Stone is now in a self-sealing state, but it will still leave a small opening, you have to search in different locations to find that hole, and then which soul power can enter the ......"

Xuanfeng Yizun reminded on the side......

At this moment, Yun Feng didn't dare to be careless, and continued to control his soul power to continue to explore. This is related to his future, and Yunfeng has no capital to start over......

"Huh...... Found ......"

Just as Yunfeng continued to explore, it took a full hour to finally find a very thin hole at the sharp corner of the fusiform. Because it was too thin, I didn't even notice it in front of Yunfeng. But the soul power is formless and substantial, and no matter how thin the hole is, it can also enter. Yun Feng controlled a wisp of soul power and finally squeezed into which small hole......

"Boom ......"

The space boundary stone suddenly shone brightly, dazzling, and even Kang Pan and Sun Meng, who were far away at the entrance of the cave, felt dazzling and couldn't open their eyes......

"Huh...... What is this place......"

In front of me was a circular space, large enough for a house, and in the center of the space, there was a suspended fusiform like the space boundary stone, but it was transparent. The color of the eyes is very different, and the shape is generally the same......

"Boy, that's the core of the space, that is, the core of the space boundary stone, this place is only accessible to you, and it is also the place where you build space. Now, try to inject your soul power into the core of the space, as long as this step is successful, this space will be yours. Now, just because the Space Boundary Stone has no owner, and it is nourished by your blood, it has no repulsive effect on you for the time being, you need to quickly let it recognize its master......"

Yun Feng was shocked, this is not his own, he is donating blood and soul power, why haven't he conquered this space boundary stone!

Yun Feng didn't care about complaining, and hurriedly used his soul power to wrap the past harmoniously towards the space......

"Ah......h

Yun Feng suddenly had a splitting headache......

Just when Yun Feng's soul power touched the space core, the space core emitted a powerful attraction, absorbing Yun Feng's soul power. That's not all, it frantically absorbed the remaining soul power in the Cloud Wind Soul Sea. It's like pulling away the cocoon, and Yun Feng has a headache......

I don't know how long it took, Yun Feng felt that his soul power had been exhausted, and his perception of the outside world had been lost, and only then did the spatial core stop. Yun Feng lay on the ground panting heavily, which was more painful than dying once......

"Hey, boy, it's still not your strength enough, it's really hard for you to build space now......"

Since Yun Feng met Xuanfeng Doctor, this is the first time he has heard Xuanfeng Doctor's regret. It is conceivable that the pain experienced by Yunfeng can be seen......

"But now is not the time to breathe, and if you work harder, you can succeed. Pierce your stomach with your sword, and place the Spatial Boundary Stone on the wound ......"

What, stabbing yourself with a sword, isn't this self-harm? Yun Feng couldn't wait to jump up and scold Xuanfeng Yizun. However, at this time, Yun Feng really had no strength, otherwise, Xuanfeng Medical Venerable would really have to be scolded......

Yun Feng knew that now was not the time to stop and rest, let alone scold Xuan Feng Doctor. took out his cloud knife, gritted his teeth, and stabbed it into his stomach......

"......"

A bloody arrow erupted......

The painful Yunfeng was pulling out all over his body......

Gritting his teeth, Yun Feng pasted the Space Boundary Stone in his hand to the location of the wound......

"Boom ......"

I saw that when the Space Boundary Stone was attached to the wound, it turned into a ray of red light and sank into Yun Feng's body. What's even stranger is that the wound that Yun Feng stabbed out with his own hands just now has healed in the blink of an eye. If there was still a scar left, Yun Feng really doubted that he had ever done it and stabbed that scar for himself......

"Boy, introverted, try to find the ...... of the Space Boundary Stone"

Yun Feng used the wisp of soul power that he had left, looking for it in his body. Sure enough, he found the Spatial Boundary Stone in the location of his stomach. It's just that the space boundary stone laughed a lot at this moment, and it was probably the size of a date pit. It's like a sarcoma with a polyp next to the stomach, and even the color is the same as a muscle......
