"Xiao Qi, then how are you going to treat me?" Yuan Yufei asked.

"Master, I'm going to implant a spatial crystal in your dantian location. According to the information records in the Moon God Palace and the experience provided by the Moon Shadow. This should be the best solution. Moreover, this kind of surgery is very mature in the Federation of Universes, and the success rate is also very high, which can reach more than 99%. Star Seven said.

Yuan Yufei still knows this, although the implantation of space in the human body, this kind of surgery has not yet been popularized to the public, but Yuan Yufei's grandfather is the president of the Academy of Cosmological and Space Sciences. So Yuan Yufei knew that in some space special forces, there was this kind of implanted space. It allows special forces soldiers to easily carry a large number of supplies and weapons.

However, Yuan Yufei still frowned and said, "Xiao Qi, this doesn't seem to be good!" These spaces seem to have a service life, if the service life is up, wouldn't I have to change the space, then will my cultivation be in vain? ”

"Master, please rest assured, the space crystals I carry are all ultra-high-grade latest research and development products, although the service life is some, but the service life is as high as hundreds of millions of years. Although in the world of cultivating immortals, with the improvement of cultivation, the lifespan can be increased, but hundreds of millions of years should be enough. Star Seven said.

"Xiao Qi, since the dantian space is used to reserve spiritual power, with the improvement of cultivation, more and more spiritual power will be included in the dantian space, will it explode the crystal space?" Yuan Yufei was still a little worried.

"The space crystal I carry is growable, and as long as it is implanted in the human body, it will not only not be burst, but will grow bigger and bigger. There is no big difference with the dantian space of immortal cultivators. Star Seven said.

"Moreover, it is even more difficult for immortal cultivators to open up space in their own dantian, and to cultivate the space bigger and bigger. Every time you ascend a level of cultivation, it's like breaking through a piece of the sky, and it's very difficult. Star Seven continued.

"But if the crystal space is implanted in your body, your dantian will have a lot of space. Cultivation can directly enter the Qi refining period. And within a certain amount of cultivation, your upgrade breakthrough will be much easier than that of ordinary immortal cultivators. Star Seven continued.

"Until the spiritual power incorporated into your cultivation has reached the upper limit of the crystal space, then you, like other immortal cultivators, need to rely on your own efforts." Star Seven continued.

Yuan Yufei thought about it, although she didn't know anything about cultivating immortals, but as the granddaughter of the president of the Academy of Space Sciences of the Universe Federation, and one of the top outstanding students of the Federal Academy of Science and Technology, Yuan Yufei was naturally a smart person and considered it very comprehensively.

"Xiao Qi, even if the crystal space is implanted in my body, it won't be able to produce a spiritual root, right?" Yuan Yufei asked.

"Yes, master."

"What's the use of that? Even if I have crystal space, I can't absorb the spiritual power in the air? Yuan Yufei said.

According to the information provided by Xingchen No. 7, Yuan Yufei knew that the reason why only people with spiritual roots can cultivate is because people with spiritual roots can absorb spiritual power of the same attribute in the air, for example, people with fire spiritual roots can absorb the spiritual power of the fire attribute in the air, and people with water spiritual roots can absorb the spiritual power of the water attribute in the air. However, people who do not have spiritual roots are almost unable to absorb the spiritual power in the air for cultivation, although there are exceptions, but that exception is almost a probability of one in a million. Very little.
