The underworld, somewhere in the space of a rock formation. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

A young man with a naked upper body is pinching his hands and meditating.

This young man is the shepherd, and he has been practicing penance here for more than eight months.

The aura of the surrounding void veins, with a trajectory invisible to the naked eye, turned into a trace of pure fire element, drilled into his body along the pores and nose of Mu Yu, and finally merged into the dantian along the specific meridians.

The qi of the leylines is the strongest in the fire attribute, followed by the wood attribute.

Where there is a dual-attribute aura of fire and wood, it is the most suitable for alchemy, and where there is a dual-attribute aura of fire and gold, it is the most suitable for refining.

Otherwise, why did so many alchemists choose a place where earth and fire gather as their cave?

Sneer~~

As Mu Yu accelerated the absorption of the leyline qi, a large amount of sweat densely covered his body turned from liquid to gaseous in the violent temperature, and there was a trace of white mist around him.

"Huh" Mu Yu opened his eyes, stretched his sour arm, took out a grain ......of Bigu Dan from the storage bag, and swallowed it.

With his current cultivation, he can't do it yet, and he won't have to eat or drink for three or five days at most.

"It's been more than four months, and I still haven't made any progress. He frowned, thinking.

"Black Tiger Body Refining Dafa" is not too advanced and profound body refining exercises, but it also took three years of Mu Yu to cultivate to the first peak.

"That reckless man of the Giant Sword Sect, it took twenty years to refine the body, I have only been working hard for three or five years, and I have already touched the second realm, compared to him, I am already a very fast cultivator......" Mu Yu said secretly, in a sense, refining the body is much more difficult than refining qi, for example, there are many pills suitable for refining qi, but the pills suitable for refining the body are extremely rare, from this point, there is a gap-like difference between the two.

"Go on! If you don't succeed in one year, then two years, if you don't succeed in two years, then three years!" Mu Yu's eyes flashed with determination, and after a short rest, he suppressed the boredom in his heart and continued to meditate.

......

......

Year after year, the peach blossoms have bloomed four times.

Four years later, still there, still the same youth.

Boom!!

Suddenly, a dull sound echoed in the underground rock world, Mu Yu suddenly opened his eyes, stretched out a punch, and slammed forward, only to see that a distorted air wave rushed forward like a drill, and then smashed on a hard rock, the rock that was comparable to the hardness of a Lingbao-level magic weapon, under the power of Mu Yu's punch, it actually shattered the size of a thumb!

"Refining the body is complete!" Mu Yu looked ecstatic, and suddenly let out a long howl, echoing for four or five miles.

After four years of hard work, the "Black Tiger Body Refining Dafa" was finally cultivated to the second realm by Mu Yu!

"Try how far I can go with one punch. Mu Yu got up, took a horse step, stabilized his body, and then, he used the spiritual power in his body, a trace of violent power, along the meridians opened up by cultivating the "Black Tiger Body Refining Dafa", and gathered in Mu Yu's right fist.

Gradually, a trace of black qi appeared, condensed into crystals, and covered Mu Yu's fist.

"Drink!" a low roar, Mu Yu suddenly swung his arm, and his fist slammed forward with his arm.

Before touching the rock in front of him, a piercing air wave echoed in the space, shaking down a large amount of earth chips, and even trembling slightly more than once.

Rumble!!

The condensed black tiger head let out a low roar, and under the whirling of qigang, it suddenly smashed into a rock in front of it, and suddenly, a spider web-like trace appeared, and quickly spread around.

That is, in the blink of an eye, this rock, which is comparable to the hardness of the inferior Houtian Lingbao, was split apart, and the rare earth behind it was also crushed by the fist wave, and a passage of more than ten zhang was excavated.

"My strongest fist power can definitely smash the lower grade of the acquired spirit treasure, even the monks in the late stage of foundation building, take a punch from me, it is estimated that if you don't die, you will be seriously injured!" Mu Yu muttered softly.

That reckless man of the Giant Sword Sect, with Qi Refining and Cultivation, harnessed the second power of the "Black Tiger Body Refining Dafa", except for the spirit treasure, any magic weapon split on his body, at most a little bit of skin, a pair of fists can easily break the bones of the ninth-layer monk in the Qi Refining Period.

As for the pastoral language, it is comparable to the cultivation in the middle stage of foundation building, and the second power of the "Black Tiger Body Refining Dafa", the two are not only in cultivation, there is a big difference in realm, but also in the strength of mana, it is even more different.

Mu Yu looked at the white ape puppet, before, his fist could only be on the white ape puppet, leaving a fist pit, but now ......

"Attack me!" As soon as Mu Yu's thought moved, the divine imprint in the white ape puppet's body suddenly harnessed it, and smashed his fist at Mu Yu.

Laugh at~~

Before the fist arrived, a strong wind rushed towards him.

Mu Yu's eyes flashed, he let out a low snort, and raised his fist to slam the white ape puppet.

Boom......

For a long time, a dull sound echoed in this underground space, and a large amount of earth chips were shaken down and sprinkled all over the body.

Looking at the trace of cracks on the fist of the white ape puppet, Mu Yu suddenly laughed, one punch!

Shake off the dirt and dust on the body, under the light of the night pearl, on the bronzed skin of the pastoral language, a slight glow, the lines of the muscles outline a sense of beauty, every time the arm is loose and relaxed, there are small pieces of muscle bumps.

Bang!

Mu Yu smashed his fist into the underground rock formation, and continued to dig deep into the leylines.

Twenty-four, twenty-five, twenty-six......

Thirty miles, thirty-one miles......

When he reached thirty-six miles, Mu Yu stopped, gasping for breath, the pressure from the ground was squeezing his body all the time, if he hadn't cultivated the second realm of the "Black Tiger Body Refining Dafa", when he reached thirty miles, it is estimated that his body would have died because he couldn't bear the pressure of the ground, causing his blood vessels to burst, and the blood that was squeezed out broke through his skin, right?!

Shaking the painful fist, Mu Yu grinned, and with a move of his right hand, three flying swords appeared, and with a finger of his hand, he replaced his fist and chiseled the rock layer.

......

After a while, the pastoral language stopped, and when it was forty-two miles underground, the oxygen was almost gone, and Rao was the current physical fitness of the pastoral language, if he could not breathe with oxygen for a long time, he would have to suffocate to death.

"Hey, this place ......" Suddenly, Mu Yu let out a soft sigh, and he stroked a rock layer with his hand, feeling it carefully.

A strong breath of earth veins followed Mu Yu's palm, drilled into his body, and along the meridians, into the dantian.

"Why is the leyline qi behind this rock layer so much stronger than that in other places?" a trace of surprise flashed in Mu Yu's eyes.

After a little hesitation, Mu Yu pinched the trick with one hand, harnessed the three flying swords, and slashed towards this rock layer.

Sneer~~

Dirt chips flew everywhere, and a large number of debris pieces fell off.

After about half an hour, the rock was finally excavated, but the rare earth layer behind it was much harder than before, and the soil solidified together, and under the knocking, it made a "bangbang" sound.

"This is the ......" When the pastoral language excavated a length of more than ten zhang, suddenly, a long cyan vein shining with a trace of orange-red mist appeared in front of the pastoral language.

Leylines!

"No, to be exact, this should be a branch of the leyline!" said Mu Yu's eyes flickered, and he said secretly.

The leylines are like the roots of a tree, but there is only one main vein, and the rest are the extension structure of the main vein, such as this branch vein, which is part of the leyline, not an independent individual.

And each root of the tree is an independent body, which is combined to support a tree to thrive.

Mu Yu ran the nameless sword technique, absorbing the aura in the branches, and suddenly, there was a pain in the body as if it had been burned by fire, but then there was a feeling of numbness, and the will was flickering.

"One day underground is equal to ten days on the ground!" Mu Yu's expression flashed with a hint of ecstasy, just cultivating next to the branch vein, it has such a terrifying effect, if you can get close to the main vein, one day of cultivation should be equal to a few days of penance on the ground?

"It's no wonder that the bigger the sect, the better the geniuses and the stronger the cultivators, sometimes, talent is important, but cultivation resources are also indispensable, even higher than talent!" Mu Yu said secretly.

"It's a pity that this leyline is close to drying up, like this branch, there are still some leyline qi left, which is really rare, even if I am lucky today......" Mu Yu shook his head.

He had heard that thousands of years ago, above this leyline, there were seven three-grade peak sects, and even one of the sects, thanks to the strong qi of the leyline, coupled with thousands of years of accumulation, successfully completed the rebirth and promoted to the fourth-grade sect, and then moved the sect to the northern region of Qindi Ling.

......

Mu Yu asked the three second-order puppets of the White Ape, the Bronze Tiger, and the Double Knife to guard the entrance, and released the mechanical bird to guard a mile away.

Immediately, Mu Yu exhaled lightly, touched his waist, and took out a palm-sized spirit devouring scorpion from the spirit beast bag.

Pastoral language urged the mana, formed a cyclone protective film, wrapped the spirit devouring scorpion, and threw it on the branch vein, and in an instant, a faint earth fire qi surrounded the cyclone protective film, and the violent high temperature made the spirit devouring scorpion become agitated, and kept shouting at the pastoral language.

Mu Yu ignored it completely, took out the "Strange Insect Compilation" seized from the senior brother of the Five Poisons Sect and began to study it carefully, turning a certain page, and the method of domesticating the spirit devouring scorpion came into Mu Yu's eyes.

"The leyline aura is composed of the dual attributes of wood and fire, after thousands of years, the leyline energy has gradually dried up, and the power of the earth and fire is also very weak, far from the domineering of burning all things, with the protection of my mana cyclone, this point of earth fire temperature, should not burn the devouring spirit scorpion...... And in the leyline qi, the residual wood attribute aura is of great help to the evolution of the spirit devouring scorpion. The shepherd said softly.
