After nightfall, the yang energy between heaven and earth drops to a minimum, and the yin energy diffuses.

Zhang Ruochen stopped cultivating to prevent the yin qi from soaking into the meridians and affecting the power of the "Sun Vein Sword Wave".

Zhang Ruochen took out the purple beast control crystal from the storage ring and put it on the ground.

The purple light reflects the night sky in psychedelic colors, and even the water in the pond next to it condenses a layer of purple brilliance.

Zhang Ruochen called Kong Xuan, who was comprehending the sword intent, over, motioned for her to sit down, and asked, "How is the comprehension?"

Kong Xuan sat on the ground cautiously, with a pair of slender ** left and right side plates, his hands on his knees, his round chest, slender waist, and sat straight.

Behind her, a pair of colorful wings appeared under the reflection of purple crystals, and particles of light appeared, like a rain of colorful light enveloping her delicate body.

Kong Xuan's voice was soft, crisp and pleasant, and said: "Back to the master, the slave maid has already comprehended some sword intent, but it should take some time to reach the initial realm where the sword can go with his heart." ”

"No hurry!"

Zhang Ruochen pointed to the purple beast control crystal and said, "Do you know what this is?"

"The slave doesn't know. Kong preached.

"This is a beast control crystal, very precious, through it, the warrior can influence the mind of the beast, so as to control the beast, help himself to attack the city and kill the enemy. ”

Zhang Ruochen said again: "It also has another function, which can test the spiritual power of a martial artist. You press your palm on the crystal and try to empty yourself and feel the energy in the crystal. ”

Kong Xuan followed Zhang Ruochen's instructions, rolled up his sleeves, revealed his snow-white jade-like arms, stretched out a weak and boneless jade hand, and gently placed it on the surface of the purple crystal.

Her eyes slowly close, forming two attractive eyeliners with fine, neat lashes.

I have to say that as a peacock half-human, Kong Xuan does have a strange sense of beauty on his body, with delicate facial features, delicate skin, and a graceful figure, which is simply a charming stunner.

Of course, Zhang Ruochen didn't pay attention to the beauty on her body, but stared at the purple crystal, saw lines appear on the surface of the crystal, and nodded lightly.

After a long time, Kong Xuan opened his eyes, withdrew his palm, and asked, "Master, what is the strength of my spiritual power?"

"Fourteenth Order. Zhang Ruochen said.

"Is it low?" Kong Xuan said a little nervously.

Zhang Ruochen shook his head and said, "Generally speaking, the older a person is, the higher his mental power. Of course, if you don't specialize in cultivating spiritual power, no matter how high it is, it won't exceed the fifteenth order. A normal person, after reaching adulthood, should have a spiritual power of about the tenth order. When you reach the twelfth order, you can already be called a genius. Reaching the fourteenth rank is already quite remarkable. ”

"Don't be too happy, those who are truly spiritually powerful can even reach the tenth order when they are born, the twentieth order when they are ten years old, and the thirtieth order when they are adults. ”

Of course, the existence of Zhang Ruochen who defies the sky is difficult to appear in 10,000 years.

The reason why I said that was because I didn't want Kong Xuan to be too proud and complacent.

Zhang Ruochen also pressed his palm on the purple crystal and began to test the strength of his spiritual power.

"Wow!"

The light of the purple crystal became stronger and stronger, illuminating the entire cultivation mansion.

Fortunately, there was a formation in the cultivation mansion, otherwise it would definitely alarm other students.

"The master's mental power is really strong!"

Kong Xuan sat aside in shock, looking at Zhang Ruochen who was sitting upright as if he were sacred, with a look of obsession in his beautiful starry eyes.

The light gradually dissipated, and Zhang Ruochen withdrew his palm.

"Master, what level of your spiritual power has you reached?" Kong Xuan asked.

"Thirty-six steps. ”

Zhang Ruochen did not hide it from Kong Xuan.

"The master is the legendary genius of spiritual power!" Kong Xuan said in amazement.

"Sort of!"

Zhang Ruochen smiled and said, "The more your spiritual power goes, the more difficult it is to improve, and with my current spiritual power realm, it is difficult to improve to the first level." ”

"If you can reach the fortieth order, the power of spiritual power will be initially revealed. Even with just one look, he could control the Heavenly Extreme Realm martial artist and turn him into a puppet. ”

"Moreover, when the spiritual power reaches the fortieth level, it can also have some magical abilities, such as: opening the eyes of the sky, cutting life and death, calling wind and thunder, and stargazing. ”

"The so-called: Open the Eye of Heaven is to condense a unique spiritual power eye in the center of the eyebrows, you can see the mineral veins hundreds of feet deep in the ground, you can see the luck on a person's body, you can see the hidden formation inscriptions, and you can also see the ghosts in the two worlds of yin and yang. ”

"Breaking life and death means that you only need to look at a person at a glance to see how many years he has to live, and you can judge on which day he will die. Except, of course, for unnatural deaths. ”

"Calling the wind and thunder is to use spiritual power, calling the wind and rain, and running thunder and lightning. The First Central Empire was set up with the Thunder Department, the Rain Department, the Wind Department, the Yin and Yang Department, and so on. The messenger of the Thunder Department is called the 'Thunder Master' by ordinary people. The messenger of the rain department is called the 'rain master'. The envoys of the Ministry of the Wind are known as the 'Wind Masters', and their main responsibility is to regulate the climate of the Kunlun Realm and manage the order of some mysterious things that ordinary warriors do not know. Of course, their own strength is also quite strong. ”

Kong Xuan said in surprise: "Their spiritual power has reached more than the forty ranks?"

Zhang Ruochen nodded and said, "Yes." ”

Kong Xuan asked, "Then what does 'stargazing' mean?"

Zhang Ruochen said with a smile: "Stargazing is a bit mysterious, and it is said to be related to the starry sky above our heads. ”

In the eyes of those sages, the starry sky in the sky corresponded to the situation on earth. By looking at the changes of stars, celestial bodies, and constellations, it is used to interpret the changes of everything in the world, and even predict the major events that will occur in the future. ”

"Really?" said Kong.

Zhang Ruochen shook his head and said, "My spiritual power has not yet reached the fortieth level, and I can't understand the thinking of those sages, I can't see through the stars, and naturally I can't look at the stars. How do you ask me to answer?"

Kong Xuan said: "It can not only open the eyes of heaven, but also cut life and death, call the wind and rain, and even watch the stars, the spiritual power is already so powerful when it reaches the forty ranks, if the spiritual power reaches the fifty steps, what should it do?"

Zhang Ruochen said: "If the spiritual power reaches the fiftieth level, you can become holy. Once sanctified, they can live for 360 years, which is several times the lifespan of ordinary people. ”

"Okay, I've told you so much about it, in fact, I want to tell you the importance of mental power. The higher your spiritual power, the more helpful it will be for you to comprehend sword intent and cultivate martial arts. Moreover, if you want to break through to the Heavenly Extreme Realm, your spiritual power must also reach the twentieth order. ”

Zhang Ruochen didn't want to cultivate his spiritual power to the fortieth rank earlier, but it was too difficult, and he couldn't rush it.

Zhang Ruochen put away the beast control crystal, took out a white bone more than ten meters long, and put it in front of Kong Xuan.

That white bone contained a rich flame power, crystal clear, like a blood jade pillar with interlaced canine teeth, exuding a powerful brute beast aura.

"This is the backbone of the fourth-order brute beast Fire Cloud Wolf, do you know what it is for?" Zhang Ruochen said.

Kong Xuan shook his head.

Zhang Ruochen smiled and said, "The backbone of the fourth-order brute beast contains bone marrow essence, also known as 'spirit marrow', and if you take it for a long time, you can improve the spiritual power of a martial artist. ”

Immediately afterwards, Zhang Ruochen took out a half-meter-high jar and two bronze wine glasses, and placed them on the ground at the same time.

"Wow!"

The five fingers were pinched into a palm knife, and the white bone more than ten meters long was neatly cut.

Zhang Ruochen poured out the spiritual essence contained in the white bones and put it into the jar.

All the spiritual essence was emptied, and the jar was half filled.

Twice the spiritual essence was poured out of the jar, one of which was handed to Kong Xuan, and the other cup was picked up by Zhang Ruochen himself.

The Fire Cloud Wolf was originally a flame-attribute brute beast, and the spiritual essence bred in its backbone naturally also had a flame attribute.

The spiritual essence in the wine glass is crimson, like a flame burning.

Just by pinching the wine glass, you can feel a hot power.

Kong Xuan just put it to his lips and took a sip gently, and he felt that he had drunk a mouthful of flame, his whole body was hot, and the meridians in his body seemed to be burning.

Zhang Ruochen picked up the wine glass and directly swallowed all the spiritual essence inside into his stomach, and after a while, the spiritual essence was refined by him.

Subsequently, Zhang Ruochen drank two more cups in succession.

Kong Xuanqiang endured the burning heat in his body and drank all the spiritual marrow.

Her body was like a furnace, the true qi and blood of her whole body were boiling, her spirit was extremely excited, and her originally white and crystal jade skin was also covered with a faint red light, and her body seemed to be torn apart.

"Hmmm......"

Just when she was about to lose some of it, Zhang Ruochen pressed one hand on her back and began to help her refine the power of the spiritual essence.

Half an hour later, the red light on Kong Xuan's body gradually converged into his body.

Zhang Ruochen took Kong Xuan into the cultivation secret room, took out the Demi-Saint Holy Intent, hung it on the stone wall, and said, "After swallowing the spiritual marrow, comprehending the Demi-Holy Holy Intent can make your spiritual power progress at the fastest speed. ”

Under Zhang Ruochen's instructions, Kong Xuan quickly settled down, and his spiritual power entered the world of holy intent.

At the same time, Zhang Ruochen also sat under the Half-Saint Saint Intent and began to cultivate.

The next day, the sun rises.

Yang energy, return to the earth.

Zhang Ruochen put away the Half-Saint Saint intent and began to continue cultivating the "Sun Vein Sword Wave".

Kong Xuan sat under the stone wall and began to comprehend the sword intent.

After a night of spiritual power cultivation, her spirit appeared to be unprecedentedly full, her face was full of red light, her sharp spirit was compelling, and even her skin was full of charming color.

In this way, Zhang Ruochen cultivated the "Sun Vein Sword Wave" during the day, and comprehended the demi-saint saint intent at night, and seven days passed.

Seven days later.

It was noon, and the sun was blazing.

"Sun Vein Sword Wave!"

Zhang Ruochen pinched his fingering, his thumb became extremely hot, and the sword intent and true qi were harmonious.

With Zhang Ruochen's finger as the center, a translucent energy circle with a diameter of ten zhang is formed.

The circle of energy, rapidly contracting, condensed at the fingertips.

Point out.

"Whew!"

A crimson sword wave flew out from Zhang Ruochen's left thumb, making a sharp sound, forming a majestic sword path, flying over a distance of dozens of zhang and hitting the wall.

"Boom".

The sword wave pierced through the wall, leaving a huge circular hole two meters in diameter.

The stone walls around the cave have melted almost completely, dripping drops of magma. When the magma cools, it forms a mirror-like structure.
