Xu Qingfeng originally thought that when he was cultivating, he didn't understand the Taiyin Sutra thoroughly, or missed a key step, or misunderstood a certain mental formula, but when the amazing sword qi in his body appeared, he didn't think so, but felt that in the first two realms, he didn't need to cultivate at all, and could directly cultivate the last realm.

In fact, he only guessed half correctly, "The Great Wilderness Sutra" originally contained easy tendons, easy bones, and easy marrow, otherwise how could he hit the tree.

Being able to break a tree without injuring oneself is a very strict requirement for the physique, whether it is skin and flesh or bones, it must be able to withstand the impact of external forces.

And in order to improve the strength, in the process of running, it is necessary to increase the speed, which also needs to adapt to the speed of the physique, otherwise the air flow generated in the air after acceleration alone can tear the person apart.

When he was ten miles away, Xu Qingfeng had already completed the first two realms of the "Taiyin Sutra" after cultivating the "Great Wilderness Sutra" and absorbing the Yuehua, but he was not a qi practitioner, and he didn't need to build a foundation, he only needed how to convert the power of Taiyin into Taiyin True Fire, and then convert Taiyin True Fire into True Fire Sword Qi, turning the power of Taiyin in his body into a kind of magical magic.

The Taiyin True Fire the size of an egg yolk in the lower dantian began to shrink, compressing from the egg yolk to the size of a mung bean, but it still didn't stop, and it continued to shrink.

The Taiyin True Fire is the most yin and cold fire in heaven and earth, which can absorb all kinds of yin and cold things in heaven and earth, and is also the nemesis of the most rigid and yang things in heaven and earth.

The sword qi is fast and sharp, a kind of momentum, and a kind of murderous aura.

When the Taiyin True Fire combined with the sword qi and turned into the Taiyin Sword Qi, a cold, sharp and murderous aura appeared, as if the space in the body was frozen, splitting a gap.

However, this is the breath that Xu Qingfeng has bred, and it does not do any harm to himself.

The Taiyin True Fire was finally compressed to disappear and converted into a trace of Taiyin Sword Qi, although it was invisible to the naked eye, Xu Qingfeng could feel that this trace of sword qi was erected in the lower dantian.

Sure enough, as a conjecture, the first and second formulas of the "Taiyin Sutra" are useless to themselves, and what they need is the last one.

Only the last article reflects the hardships of cultivation, which requires perseverance and slow accumulation in order to reach Dacheng and practice supernatural powers.

According to the "Taiyin Sutra", after the sword qi appears in the body, it needs to be warmed and strengthened, and after the sword qi becomes the final Taiyin sword with all shapes and qualities, it is a great success, and it can be released to kill people and defend itself.

However, even if there is no Dacheng, it can be released to defend against the enemy, but the power is much smaller, especially Xu Qingfeng, a trace of sword qi that has just been condensed, it is not recommended to release it.

After all, there is only a trace of sword qi, and not only is it not lethal after it is released, but it will also hollow out the sword qi in the body, and it is necessary to recondense a trace of sword qi before it can be recuperated.

In fact, after cultivating the first method, Xu Qingfeng knew that he had obtained a magical power, that is, he could directly draw the Taiyin True Fire out of his body and launch a fireball, but this kind of fireball can deal with ordinary ghosts and zombies at close range, but if it is a little farther away, or a monk, it will be a little beyond the reach of the whip, and it will have no effect at all, after all, the fireball that flies out is not only slow, but also does not fly far.

It is not easy to condense sword qi in the body, who has not succeeded after several attempts and a long time, but Xu Qingfeng didn't know at all, after easily condensing a trace of sword qi, he thought that condensing sword qi was very simple.

The whole person was excited, and he couldn't wait to try it out, after there was no sword qi in his body, everything needed to start from scratch.

The sword qi was invisible, but with the Taiyin True Fire, it turned white, only a few inches long, and the silk thread was thick, which penetrated from Xu Qingfeng's fingers and fell less than half a foot from the ground, without causing any damage to the ground and walls.

Xu Qingfeng was not disappointed, as long as he successfully displayed his sword qi, he was already very satisfied, which meant that from now on, there was one more means to resist the enemy.

Because he was worried about Mu Mu in his heart, he didn't continue to cultivate, but sank into his heart to communicate with Mu Mu again.

The cultivation secret room, at this time, was full of colors, brilliant and dazzling, all kinds of light flew all over the sky, Xu Qingfeng looked at it for a long time, and then figured out the approximately, it turned out that he was using various spells to attack Mu Mu on the ground, probably because he hadn't seen through Mu Mu's bottom for a long time, and the grimace mask man began to use spells to check.

The psychic wood and wood, from the fact that he only actively collects the frost rime fruit for more than a million years in Shilijian, it can be seen that he definitely has a high spiritual intelligence, how can he be so easily figured out. Xu Qingfeng was completely relieved and continued to practice the last chapter of the Taiyin Sutra.

......

The grimace masked man stopped casting spells, picked up Mu Mu from the ground, and said to himself in a hoarse voice: "This thing is not afraid of water, fire and various spells, and I have heard that it can fly off the ground, so it can be seen that it is a rare treasure, but I don't know how to use it for me, I am afraid that it will be slowly practiced and the mark of the original owner will be polished, but there is no time now, after all, the things that my brother explained are more important." ”

Immediately, the grimace masked man put Mu Mu on the wooden shelf next to him, walked to a wall, and touched it with his hand, the wall in front of him slowly cracked, and a transparent light curtain appeared in front of him.

There is a white mountain stone more than ten zhang high in the light curtain, covered with frost, exuding a trace of white cold, wandering in the light curtain.

The ghost-faced masked man then made a move, and an object flew out of the wooden shelf in the room and fell into his hand, if Xu Qingfeng was here, he would definitely recognize this item, it was very similar to the black banner in the hands of the Nadu steward, but it was much smaller, about three feet long.

"Ahem...... Ahem......". Before the grimace masked man could move, he began to cough violently, and his body was arched like a shrimp.

After stopping for a long time, he gasped and said to himself again: "The breath of this Taiyin cold stone is worthy of the world's most yin and cold breath, although I have been in contact with it for so many years, but every time I face it, I can't bear this breath, and I feel powerless recently, fortunately, my brother needs to divide the flag is still six sides, and it can be done, alas! If this flag doesn't need to consume a lot of my vitality, I need to absorb vitality from outsiders while cultivating, I'm afraid it will be completed long ago, how can I suffer the sin of this Taiyin breath." ”

The grimace masked figure seemed to be adapting to the cold air in the light curtain, and after a short rest, he threw the black banner in his hand into the air, so that the black flag was fixed in the air, and then made a complicated gesture with both hands, and finally pointed to the light curtain.

The cold air in the light curtain began to surge, condensing into a stream of air the thickness of a little finger, piercing out of the light curtain and connecting to the black banner in mid-air.

At this time, he saw a vision protruding, and Mu Mu, who was originally placed on the wooden frame, flew out of the wooden frame under the defenselessness of the grimace masked man, and suddenly rushed into the light curtain along the place where the cold air came out.

"Ahh......h

The next scene made the Grimace Mask Man completely crazy.

Mu Mu rushed into the light curtain and slammed at the white rock, and after a few rounds, the white stone exploded from it, becoming torn apart, and a fist-sized white bead appeared in the rubble.

"No......" the Grimace Masked Man screamed and threw himself at the light curtain.

The white beads in the light curtain suddenly emitted a thousand rays of light, enveloping Mu Mu and the Grimace Mask Man.

The grimace masked man, who was caught off guard, just threw himself down on the light curtain, and was enveloped by the light emitted by the white beads, and a silver-white flame rose from the grimace masked man's body, wrapping his whole person in flames, no matter how he struggled, he couldn't get rid of this silver-white flame.

"Too ...... Taiyin, True Fire ......" The Grimace Mask Man let out a scream of disbelief.

Gradually, the body of the grimace masked man began to distort, and the black robe and mask on his body were melted, revealing a man with a withered face and a pale face, but in an instant, only white bones remained, and then turned into ashes and scattered on the ground.

Mu Mu was against the light, approaching the white beads, looking very struggling, but slow and resolute.

The light of the white beads was even better, and all the light shone on Mu Mu, and he was frozen in the air with Mu Mu, but Mu Mu only paused for a while, and after a few breaths, Mu Mu began to slowly advance again, getting closer and closer to the white beads.

When Mu Mu saw that he was about to touch the white beads, the white beads suddenly retracted the light, crossed a curve, and rushed out, just in the blink of an eye, he rushed out of the light curtain, but Mu Mu's movements were faster than it, only to see the figure surpass the white beads in a flash, and at the moment of transcendence, the white beads were swallowed into the body, and then fell heavily to the ground, the body bent and bounced a few times, spewing out a large canopy of white mist, as if after eating and drinking, he hiccuped.

......

Xu Qingfeng was sitting in the prison, originally recuperating in his body, the sword qi that was re-condensed, his heart suddenly moved inexplicably, and when he looked at the dantian, he found that the sword qi in the dantian emitted a bright white color, which became clearly visible, and it was unbelievable that a sword phantom of an inch long had formed, and he couldn't help but feel something, thinking of Mu Mu.

When communicating with Mu Mu, he found that there was no one next to Mu Mu, Xu Qingfeng couldn't help but be a little happy, it was the time to flee at this moment, he didn't pay attention to the surrounding prison stone walls at all, the formation of the Ten Mile Stream back then could be broken, and the prison wall in this district could be compared to the Ten Mile Stream Protection Formation.

Just when he tried to recall Mu Mu, he found that Mu Mu had no movement, although Xu Qingfeng could communicate with Mu Mu and could see Mu Mu, but as long as he summoned Mu Mu, he would find that Mu Mu did not fly back to his side through the void as usual, but still stayed on the ground in that room.

At this time, Xu Qingfeng was anxious, Mu Mu was not only a treasure, but also a relic left by his mother, even if his life was in danger, Mu Mu could not be lost.

Xu Qingfeng stood up and randomly chose a direction to crash into.

Rumble!

A large humanoid hole had been knocked open in the stone wall, and it was pitch black outside.

Xu Qingfeng didn't stop walking, and continued to hit straight forward, and an exclamation came from the darkness behind him.

Boom! Boom!

The roar of one after another sounded in the darkness, and Xu Qingfeng crashed into more than a dozen cells in a row, but he didn't see the light or the way out, so he couldn't help but stop temporarily.

"Did you go in the wrong direction?" Xu Qingfeng couldn't help but wonder a little, and reflexively crashed in another direction.

Rumble...... Boom......

This time, Xu Qingfeng quickly returned, stood in the dark prison, and sighed: "Why did you go in the wrong direction again, and the front is full of mud?"

"Before, senior, what are you looking for?" someone in the darkness asked cautiously.

"Is there someone in this cell? Why didn't I find out just now?" Xu Qingfeng was very surprised.
