Before he knew it, Chen Kai meditated for several hours, and the spiritual energy absorbed in his body had been temporarily saturated, so he stopped practicing. When he opened his eyes, he saw Xuan Ling sitting on the Han Yu bed next to him, with his big eyes open and smiling.

"Uh..." Chen Kai was stunned, and couldn't help but touch his nose, looked at Xuan Ling, and said, "What are you doing when you look at me like this?"

"Hehe, it's okay. I just like to look at you like this. Hey, I find that you are very charming when practicing quietly, and people can't help but want to get close to you..."

Xuan Ling tilted her head slightly, blinked her big eyes, and said to Chen Kai.

Chen Kai pursed his lips and shrugged, "Is there any? It seems that I am quite handsome, so I can let Xuanling appreciate it so much."

"Hehe, right, yes, you are very handsome!" Xuan Ling smiled and reached out to pinch Chen Kai's cheek.

Chen Kai was a little embarrassed, but then said, "Okay, you pinch my face, see if I don't pinch your little face..." After that, Chen Kai made a gesture and wanted to bully himself, reaching out to pinch Xuan Ling's fair and tender face, which was like a cream.

Xuan Ling giggled, let go of her little hand that was pinching Chen Kai's cheek, quickly dodged backwards, and said in a soft voice: "I won't pinch it for you, giggle..."

The two laughed for a while, and Xuanling suddenly asked, "By the way, Chen Jing, what kind of martial arts are you practicing? How did I see that in addition to the spiritual energy gathered around you, there is a layer of silver power lingering like starlight?"

Xuan Ling looked at Chen Kai curiously. She had no spiritual consciousness, and obviously could not directly judge that it was the power of the stars. After all, the power of the stars is different from the spiritual energy of heaven and earth. If she had not been exposed and had no spiritual consciousness, it would be difficult to judge by induction alone.

"Oh, I'm practicing a relatively unique technique, and this phenomenon will occur when I practice." Chen Kai said casually.

"Is that true?" Xuan Ling did not go into further research and ask more questions. After all, she has been exposed to countless various techniques since she was a child, and she is not very interested in this aspect. She was just a little surprised when she saw the silver star power on Chen Kai's body and asked curiously.

After nodding, Xuan Ling looked at Chen Kai and asked, "Chen Jing, how did you feel when practicing just now? Is it much faster than practicing outside? Hehehe."

"Well, yes." Chen Kai smiled, had an idea and said, "The spiritual energy here is too strong, much faster than I used to practice with low-grade spirit stones. I just don't know if it would be so fast if it was used to practice with high-grade spirit stones."

"Hehe." Xuan Ling laughed and said with a pursed lips: "In fact, the effect of cultivating with top-grade spirit stones is not much different from cultivating with lower-grade spirit stones. The top-grade spirit stones contain more spiritual energy and are more pure. But in fact, the speed of absorption and refining during cultivation is not much different from that of using lower-grade spirit stones. Unless the cultivation level reaches the Golden Elixir stage or above, there will be a relatively obvious gap."

"Because the lower-grade spirit stone contains relatively more spiritual impurities, it will take more time for people in the Golden Elixir stage to refine it, so the efficiency is much worse than using medium-grade spirit stones or top-grade spirit stones. However, people with lower-grade spirit stones have no impact on this aspect, because if their cultivation is not high, some impurities and energy contained in the lower-grade spirit stones are not so easy to refine. Usually, they have to rely on repeated refining of the true essence before condensing the golden elixir, and after breaking through the golden elixir stage, they can only refine all the impurities and forces that have been refined into the true essence in the past..."

Chen Kai was naturally clear about what Xuan Ling said. However, the reason why he deliberately pretended to be unknown to mention the top-grade spirit stone was to use this to ask Xuan Ling about the top-grade spirit stone.

"Oh? Is that right?" Chen Kai scratched his head in vain, and then said, "By the way, Xuan Ling, I heard you say that. You must have seen a top-grade spirit stone? I have only seen a low-grade spirit stone before, but I don't know what the top-grade spirit stone looks like!"

Xuan Ling showed some smug expressions, laughed and said, "That's of course! I have not only seen top-grade spirit stones, but also seen a lot of them. In fact, there is not much difference between top-grade spirit stones and low-grade spirit stones, but the spirit energy contained in it is more pure and pure. It also looks more crystal clear and shiny on the outside, unlike low-grade spirit stones. If you look closely, you will find that it is more or less crystal clear inside."

When Chen Kai heard Xuan Ling say that she had seen many top-grade spirit stones, he was a little happy. "Xuan Ling, I used to hear that the top-grade spirit stones only existed in the Five Heavenly Sects and the Three Qing Palaces. Could it be that... people from the Five Heavenly Sects or the Three Qing Palaces?"

Chen Kai took this opportunity to inquire.

Xuan Ling didn't seem to want to tell Chen Kai, but just smiled at him and said, "I won't tell you, hehe, you can guess it yourself!"

As he said that, Xuan Ling seemed to be overjoyed and laughed in a sweet voice.

Chen Kai had to pursed his lips and touched his nose, but although Xuan Ling did not admit it, since she did not otherwise, it was certain that she was right.

Otherwise, with the power of the Three Qing Palaces and the Five Great Heavenly Sects in the Kunlun Fairyland, how could ordinary people dare to joke like this?

"Okay, then I'll think you're the default." Chen Kai shrugged and said.

"Gee..." Heck..." He was only Xuan Ling's giggle.

"Xuanling, one day can you bring me a top-grade spirit stone? I want to see what is the difference between a top-grade spirit stone and a low-grade spirit stone." Chen Kai took the opportunity to propose.

If he could really ask Xuan Ling to get a top-grade spirit stone, then he could find a way to leave here and find Luo Shuang in the future, and then the two of them would return to the secular world.

Although he is suspected of "deceiving" the little girl Xuan Ling, in order to obtain the top-grade spirit stone and return to the secular world in the future, he can only think of a way to "take every step" in this way.

Xuan Ling seemed to have not noticed Chen Kai's intention and said, "The top-grade spirit stone is a relatively scarce resource, and it is basically sealed. Only grandma and several top elders are qualified to open the place where the top-grade spirit stone is sealed. And grandma is now in seclusion, so I can't ask her for a top-grade spirit stone to let you see it."

Xuan Ling made a helpless expression to Chen Kai.

"Didn't you say that there are still several Supreme Elders who can also open the places where the top-grade spirit stones are sealed?" Chen Kai said.

Xuan Ling spread her hands and said, "The Supreme Elder is in a secret place and doesn't know what to do. Anyway, it seems that almost all the Supreme Elders will go there forever. Unless there is something important, the Supreme Elder will not easily come out of the secret place."

"Oh." Chen Kai nodded. "Then how long does the grandma you mentioned need to be in seclusion?"

Xuan Ling said casually: "This is not certain. Anyway, grandma has been in seclusion for more than a year, and it may be one or two years. Or three or five years may not be certain. Grandma said that she should try her best to break through her cultivation during this seclusion. You also know that if she wants to break through after her cultivation reaches a bottleneck, she often has to talk about some opportunities and sudden enlightenment, so it is difficult to determine when grandma will come out of seclusion..."

After hearing Xuan Ling's words, Chen Kai couldn't help but wonder if the "grandma" in Xuan Ling's mouth was breaking through the "Nasty Soul Stage". After all, Aunt Lan has the cultivation level of the Golden Pill stage, and the grandma in Xuan Ling's mouth is obviously her real elder. And she still needs to go into seclusion for several years. If she only breaks through the middle or late stage of the Golden Pill from the early stage of the Golden Pill, she definitely doesn't need to go into seclusion for so long.

The only possibility is to break through the Nascent Soul Stage from the peak of the Golden Elixir Stage!

Thinking of this, Chen Kai couldn't help asking: "Xuan Ling, the grandma you mentioned is about to break through the legendary Nascent Soul Realm, right? Why do you have to stay in seclusion for so long!"

The realms above the Golden Elixir Stage in Kunlun Fairyland are also consistent with the realm of cultivation. Above the Golden Elixir is the Nascent Soul, and then leaving the body and distracting the spirit.

However, for the Kunlun Fairyland today, the Nascent Soul Stage has become an existence in the "Legend" in the eyes of ordinary practitioners.

Xuan Ling looked at Chen Kai, pursed her lips and said, "Well, that's great, you can guess it. Hehe, let me tell you the truth. Grandma is indeed breaking through the Nascent Soul stage in seclusion. However, I heard from Grandma that it is not that easy to break the elixir and form a baby. Broken the elixir itself is a very difficult process. It is necessary to nurturing the elixir very strongly in the golden elixir to break the shell, break it out of the golden elixir and turn it into the Nascent Soul..."

"In short, grandma said that many people are stuck at this step, and the 'yuan fetus' that are nurtured in the golden elixir is not mature enough. So until the life span is exhausted, it is impossible to take the step of breaking the golden elixir."

Chen Kai knew that in addition to the initial and middle stages of the Golden Pill stage, mainly to temper the golden elixir and accumulate strength, in the late stage of the Golden Pill, one must start fertilizing the "yuan fetus" in the golden elixir. The process of fertilizing the "yuan fetus" is very slow. It requires absorbing huge power to fertilize it little by little.

Just like when pregnant for ten months, the Yuan fetus will sprout from the initial little bit of embryos and then continuously absorb the energy of the golden elixir, slowly foster and grow. It gradually takes shape until the elixir is broken and turned into a baby.

Therefore, the entire cultivation process in the late stage of the Golden Pill requires a longer time than the combined initial stage of the Golden Pill and mid-stage of the Golden Pill.

It is common for ordinary people to spend hundreds of years on the process of fertilizing the "yuan fetus" in the late stage of the Jindan. Even if they are talented and fast in cultivation, they dare not let the "yuan fetus" be fertilized too quickly, because even if they can eventually break through to the Nascent Soul stage, the Nascent Soul itself is easily "congenital deficiency".

It's like a premature baby.

Of course, if you are really a talented person and have enough energy to nurture the "yuan fetus", this process will not necessarily take dozens or even hundreds of years.

But it will be necessary for at least seven or eight years.

Since the grandma was in seclusion, Chen Kai could only put aside his thoughts on asking Xuan Ling for a top-grade spirit stone. However, after confirming that there was a top-grade spirit stone here, Chen Kai became even more confused.

He was indeed a little worried about Luo Shuang and wanted to go out to find Luo Shuang. However, on the other hand, he wanted to wait here for the grandmother Xuan Ling said to come out of seclusion, and then find an opportunity to ask Xuan Ling for a top-grade spirit stone, so that he could solve the problem of leaving Kunlun Fairyland and returning to the secular world.

After a little tangled in his mind, Chen Kai could only suppress his concern for Luo Shuang in his heart. Now he couldn't leave, so he might as well stay here peacefully for the time being, at least he would practice much faster than elsewhere.

As for Luo Shuang... Chen Kai could only comfort himself in his heart, believing that Luo Shuang would be safe and sound. (To be continued, please search Piao Tianwen, the novel is better and faster!
