Ling Feng stayed in the dead of night, picked up the booklet of "Xuangong Illusion" again, and looked at it in the room, the fourth-level Xuanwu, the fifth-level Xuanyi, and the sixth-level Xuanxuan are an important part of the "Yellow Emperor's Internal Classic".

The muscles and veins provide the qi of exhalation, which is the main body of cultivation of internal strength, which complements each other with the third level of foundation building, and the genes collude with each other, and the qi and blood flow and circulation, so as to improve the metaphysical function.

This kind of refining and breathing qi is different from the general martial arts refining method, not sitting cross-legged meditation practice, but practicing in the dynamic breathing of true qi, galloping and breathing luck, long and short breathing to condense lasting endurance, increase internal breathing machine, and then, in the fierce battle, the internal breath is strong, and the blood pressure does not rise.

Ling Feng was looking for a favorable opportunity, and after a short period of thought, he thought of an excellent method of refining qi with a demon wolf, which was the most effective way to increase internal breath.

The next day, as soon as the sky brightened, Ling Feng walked out of the inn gate and rushed towards the forest of Dabie Mountain.

Soon, Ling Feng came to the edge of the forest, observing the movement in the forest, he hid himself step by step into the forest, and arrived at a wide area, his eyes swept away the bones on the ground, only some rags remained, scattered around, it seems that those dead Jianghu men have gnawed away the bones of the demon wolf.

Ling Feng knelt on the ground and listened, and there was a slight gasping sound in his ears, if there was nothing, intermittently, it was difficult to hear it if he didn't listen carefully.

Ling Feng's heart froze, this was the wheezing sound from the demon wolf, it could be seen that the inner scripture had reached the superior realm.

Neijing, is the meridian and veins recorded in the "Xuangong Illusion", Qi refining practitioners, from the meridians of blood circulation, absorb the pure aura between heaven and earth, condense into crystals little by little, and gradually accumulate in the five organs to accelerate the circulation, the aura of essence diffraction to produce a synthetic effect, rise to the power, the more sufficient the essence, the stronger the skill, the essence is inexhaustible, and the skill is inexhaustible.

Ling Feng was even more surprised when he thought of the demonic beast that had evolved into a spirit five hundred years later, and he began to refine qi on the demonic wolf.

Early in the morning, it is the most time for the release of spiritual energy between heaven and earth, it seems that the demon wolf surname is even more, and he also knows how to refine qi, absorbing Linghua essence and refining the internal meridian qi machine on the ground.

Ling Feng Qi refining is a dynamic surname, contrary to the Demon Wolf Qi Refining, he must accumulate essence in action, slowly gather less into more, the breath vein door opens, like a flood surging forward, complete the third-level Qi refining effect, and at the same time improve the quality of Xuan Gong, decided to get rid of this group of demon wolves, and help himself enter the fourth-level Xuan Wu Qi gathering stage, after thinking about it, his body rotated like a spinning top, rushing towards the demon wolf's ambush body, launching an attack to refine Qi step by step to obtain the source of spiritual energy.

The demon wolf saw a whirlwind rolling up, and suddenly felt wrapped in a peculiar smell, which emanated from the human body, and all of them straightened their ears, sighed and cracked their teeth, and their blood-red tongues were exposed from their mouths, and their eyes glowed green, flapping their wings, and attacking at any time.

Ling Feng's body floated up, he took a sharp breath of clear air, a wisp of spiritual energy went straight into his heart, he practiced the internal strength of spitting, the Xuangong mental method to control the mind, guide the pure masculine qi, and extend the eight veins of the Qi Sutra, running into the dantian, a stream of air rushed straight to the brain, and the heavenly spirit cover woke up.

Ling Feng waved his hand and split a palm, a move "Flowing Red Flying Flower", a red plum, and floated towards the demon wolf.

The demon wolf was full of demon surnames, and when he saw a red plum floating over, he hurriedly dodged in order to avoid the attack.

A red plum, five petals separated, and the five demon wolves were attacked.

The five demon wolves scurried left and right, dodging the petals.

Who knows, the five petals, "pop!", were blown into pieces and turned into pollen, which drifted around in the air with the wind blowing.

The demon wolf sucked pollen, "Horn!" The nostrils exploded, blowing up a wolf head, and there were no less than a dozen demon wolves in the forest that were killed.

The Demon Wolf Commander taught the comer how powerful it was, spread its wings, and flew towards the peak of the white horse's spire.

Ling Feng no longer rushed to the peak of the white horse, the demon wolf's attack power was strong, and it would be difficult to break out of the encirclement if he was trapped again, he was afraid of his life, so he was not in a hurry to pursue, and some of them had time to slowly consume the group of demon wolves flying across Taihang Mountain.

Ling Feng hurriedly ran out of the forest and walked towards the "Wind and Moonlight" inn.

Ling Feng returned to the "Feng Qing Yueming" inn, took out the book "Yellow Emperor Technique", and studied it again, until late at night, still looking tirelessly, he wanted to ponder the true secret of the treasure, comprehend the connotation of the artistic conception, and taste the Qi Condensation Spirit.

Ling Feng was tired from seeing, he didn't take off his clothes, he leaned sideways on the head of the bed, his eyes slightly closed and still meditating on the trick of refining qi.

"Whoosh ......" came from the sound of clothes breaking through the air, and an uninvited guest fell on the roof.

Ling Feng was a cultivator, and he had already heard it in his ears, and there were several night walkers who came to the inn to visit the house, but they didn't know why? Well, the people who haunted at night were not good people, they were either annihilated or thieves.

Ling Feng rushed to the window, swept his electric eyes, and saw several figures, one after another, falling on the window of the adjacent room, and after a while, the window opened gently, and rushed into the room one by one.

Ling Feng listened attentively, there was a commotion in the adjacent room, and soon after, "Oh! don't, save ......" A girl's cry for help came, and the voice stopped abruptly.

It's not good, there are flower thieves, it seems to be bad for girls, it seems that the overlord is going to bow hard!

Ling Feng turned around and flew towards the neighboring room.

A biao-shaped man, guarding the window of the adjacent room, saw someone following and rushing, and casually threw out a knife and slashed at Ling Feng.

Ling Feng flicked his two fingers, a red light flashed, and the knife edge reversed and slashed back towards the front door of the biao-shaped man.

The big knife was disobedient, a sharp blade light, turned one hundred and eighty degrees, and slashed back, how could it be like this? This damn big knife wants to rebel and murder its master!

Usually, the big man has done a lot of bad things, and the big knife is all in his eyes, but now, the evil slam is full of death, and the big knife wants to strike back, for the sake of the master and servant, he will give each other a ride, protect him to hell and reflect on himself, and be a good person in the next life!

The big man didn't have time to make a move, "Bang!" The blade of the big knife had reached the bridge of his nose, and he slashed it mercilessly.

"Ah......h

"Ah Biao, what are you doing?" A tall and thin man stood in the distance from the window, and when he heard that something was wrong, it was a wild scream before he died, and he couldn't help but be shocked in his heart.

After the big knife killed his master, it seemed that the bloodthirst was not yet enjoyable! The blade was not finished, and "Whew!" beckoned to the tall and thin man.
