Half a moon later, the mountain behind the floating jade peak.

A sturdy figure shuttled back and forth in the bamboo forest, accompanied by a sword.

Yan Lingyu rose into the air, and the Heaven Killing Sword flattened a large piece of green bamboo under his command, and then he collected the sword and took the shape of his hand and slashed out a sharp sword qi, "boom", a boulder in the distance directly shattered, and finally Yan Lingyu turned over and landed smoothly.

"It's been a few days since I entered the ninth layer of Qi Refining, and I don't know when Master will let me break through the Soul Forging Realm. ”

Yan Lingyu had been refining the ninth layer of qi a week ago, and it only took three days to reach the peak of the ninth layer of qi refining, but Ling Shuang asked him not to rush to break through to the soul forging realm, and then polish and polish himself.

"Go back, and be here in the morning. Ling Shuang got up and shouted at Yan Lingyu.

"Okay. ”

Yan Lingyu put her sword into the sheath and followed Ling Shuang towards the hut, and the cut green bamboos came back to life one by one behind him.

After lunch, Yan Lingyu went to rest, and continued to practice in the afternoon.

He got up after more than an hour, Yan Lingyu had already developed a habit, even if Ling Shuang didn't call him to the point, he would wake up.

Ling Shuang saw that Yan Lingyu woke up and got down from the bed in the small study, and when Yan Lingyu finished washing, the master and apprentice walked towards the place of cultivation again.

Yan Lingyu had almost never seen Ling Shuang wash his face and take a bath, and later Ling Shuang told him that the higher the realm, the more "pure" the body is, it will not produce filth, and even if he eats something, it will be directly decomposed into energy, and if he has to take a bath, he can wrap his whole body with spiritual power, so that he can also remove the dirt on his body, and if he wants to enjoy life, it is best to find a hot spring to take a dip.

When they arrived at the cultivation place, Ling Shuang set out the table and chairs and sat down as usual, Yan Lingyu was about to draw her sword and cut the bamboo, but was stopped by Ling Shuang.

"Almost, now you can try to develop your spiritual power and see if you can enter the Soul Forging Realm. ”

As soon as she heard that she could impact the Soul Forging Realm, Yan Lingyu was very excited, and nodded again and again: "Okay." ”

Looking at Yan Lingyu's excitement, Ling Shuang shook her head and took out a book and flipped it over.

More than an hour later.

Yan Lingyu sat on the ground like a mentally retarded child, his eyes were hollow, his expression was dull, what kind of mental power, what kind of thing was that, he tried to explore for a long time, but he didn't understand what mental power was at all, and the whole person was as goalless as a headless fly.

Finally, Yan Lingyu gave up, he looked back at Ling Shuang: "Master, you just let me exercise my spiritual power, but why don't you teach me what spiritual power is." Yan Lingyu's tone was a little complaining.

Ling Shuang turned the page of the book in her hand and said lightly, "You didn't ask me." ”

"......" Yan Lingyu was stupid.

But after thinking about it for a while, he quickly came back to his senses, Yan Lingyu got up and ran to Ling Shuang's side, picked up the teapot and poured a cup of tea, and then held it in both hands and handed it to Ling Shuang: "Foolish, please teach me master." ”

Ling Shuang slowly closed the book and looked at Yan Lingyu with a playful look: "Aren't you quite capable, I saw that you were so happy and thought you had learned a long time ago." ”

Yan Lingyu smiled embarrassedly: "What's the matter, I'm so stupid, if the master doesn't teach me, I definitely won't." ”

Ling Shuang took the tea handed over by Yan Lingyu and said, "The method of the Heavenly Cultivators to develop their own spiritual power is probably like this, you first close your eyes and use your spiritual power to feel an object, and then transmit the information you feel with your spiritual power back to your brain, and then sketch out what it looks like in your mind. ”

"This is done to allow the spiritual power to communicate with the brain, once the spiritual power can interact with the brain, the first step is completed, and then use its own spiritual power as a bridge to diffuse the brain waves generated during brain activity, which is considered to lead to their own spiritual power, at this time, the spiritual power of the monk is like a baby who can't walk, and the spiritual power plays the role of an adult, responsible for supporting the spiritual power to walk. ”

"Then it's a long time of exercise, after the baby can take a step, the next thing is to learn to walk alone, and then it is to walk steadily and fast, and after walking steadily and fast, you have to learn to run and fly, until one day the baby grows up and no longer needs to be supervised by an adult. ”

"Look at this purple sand teapot, it has a lid, a handle, a spout, and a pattern on the body, you close your eyes and wrap it with your spiritual power, if you can perfectly outline its appearance in your mind, this is the first step. ”

"Try it. Ling Shuang pointed to another chair and motioned for Yan Lingyu to sit down.

"Hmm. ”

Yan Lingyu sat on another chair, he wrapped the purple clay pot on the table with spiritual power according to Ling Shuang's words, and carefully sensed the shape and specifications of the teapot.

Yan Lingyu's eyes were closed, although he had seen the appearance of the teapot, but what he wanted to do now was not to know what the teapot looked like, but to "make" something exactly like the teapot on the table in his mind.

Yan Lingyu wrapped the teapot with spiritual power, and he tried his best to perceive the various data of the teapot, how high, how wide, and how long, and the information was constantly transmitted back to Yan Lingyu's brain.

A brand new teapot slowly appeared in his mind, which was an extremely difficult technical task.

Try to imagine that you are learning three-dimensional geometry, and there is a problem that is an extremely complex and multi-faceted object, but the problem requires you to draw three views of it, and then you have to figure out what it looks like in front, behind and on top.

Asking you what it looks like after cutting it from a certain place requires you to accurately imagine a space object, if you can't imagine it, you may have a huge shadow on the three-dimensional geometry because of this problem.

After a while, Yan Lingyu opened her eyes and shouted excitedly: "Master, I succeeded, I just drew a teapot in my mind, which is exactly the same as it." ”

"Well, if it works, you can try to make the perception range bigger and see if you can draw more. Ling Shuang said.

Although she sometimes scolds Yan Lingyu, she is absolutely attentive in her cultivation, and gives him the greatest encouragement and support every time.

"Okay, I'll try. ”

Yan Lingyu continued to release the spiritual power in his body, covering a small area around him, and after a while, he opened his eyes, and then ran to Ling Shuang and said the same thing as just now.

Seeing Yan Lingyu's happy appearance, Ling Shuang also smiled: "You can try to slowly condense your mental power brain core, which can greatly improve the strength of your mental power." ”

"Psychic brain nucleus? What is that? Yan Lingyu asked.

"This is something that a monk condenses in his brain with his spiritual power, similar to the dantian in the monk's body, ordinary monks will only have it when they reach the higher realm, and the ninja master who specializes in spiritual power will start to do so when they are in the lower realm. Ling Shuang explained.

Yan Lingyu thought for a moment: "Master Nian, isn't that a monk who specializes in spiritual power, why don't I study spiritual power to condense the brain core." ”

"Master Wei naturally knows that you don't study spiritual power, and doing so is to prepare you for entering the Transcendent Three Realms in the future. ”

As soon as Ling Shuang said this, Yan Lingyu was even more puzzled: "What does condensing the brain core have to do with the transcendent three realms now?"

"If a monk wants to break through the Ming Soul and enter the Transcendent Three Realms, one of the important conditions is to condense a spiritual power brain core, which is the key to the transformation of spiritual power into soul power, if it can't be done, then there is basically no hope of stepping into the Transcendent Three Realms. Ling Shuang explained.

"That means I'm going to condense a mental power brain core now?" Yan Lingyu said.

Ling Shuang shook his head: "You can draw out spiritual power so quickly, which shows that you still have some advantages in this regard, but it's best not to condense the spiritual power brain core to the death, it's not good for you." ”

"Why. ”

"I'm afraid you'll be bald. ”

"......" Yan Lingyu touched her hair and didn't speak.

Looking at Yan Lingyu's appearance, Ling Shuang couldn't help but laugh and said: "Lie to you, it takes a lot of effort and time to condense the mental power brain core, unless you are going to be a teacher, it is not cost-effective to do this if the cultivation is too low, and the spiritual power will be stronger when the realm is high, and then condensing the brain core will be twice the result with half the effort." ”

"That's the case, then why did Master just ask me to condense my brain nucleus, and then said not to do this. Yan Lingyu was a little puzzled.

"I didn't let you condense the brain nucleus now, but asked you to make some preparations for the condensation of the brain nucleus, as for why I let you start now, it's because of your special physique. ”

Ling Shuang took a sip of tea and continued: "You kid quenched the individual and shouted for the teacher, but the result was nothing to quench the muscles and veins, as the saying goes, 'hurt the muscles and bones for a hundred days', the pain of refining the muscles and veins during the condensation realm can be much greater than the quenching body, but the teacher allows you to refine the muscles and veins and bones but I haven't seen you howl, which means that the strength of the organs in your body is far beyond ordinary people." ”

"Yes, I am so good. Yan Lingyu smiled sneeringly.

"So all parts of your brain should be stronger than ordinary people, you can slowly try to condense the brain nucleus at a low level, you can do as much as you can, just follow the trend, quenching your body You are just fooling the past, and you can't do this anymore in terms of mental power." ”

Being mentioned by Ling Shuang several times about the embarrassment of quenching the body realm, Yan Lingyu blushed a little, so she had to nod her head constantly, in order to express her determination not to be lazy in the cultivation of spiritual power.
