The waterfall in the valley rushed down quickly, rumbling, and on the rocks next to the waterfall, Ren Jian sat cross-legged with his eyes closed.

At some point, the sky was gray, dark clouds obscured the sun, and even a trace of light was stingy to the earth, and gradually, a misty drizzle began to fall in the sky.

The drizzle fell, Ren Jian's body seemed to hold up an invisible air cover, the rain had already vaporized before it touched his clothes, and at the same time, a black gourd was suspended in front of him, with a trace of milky white light flowing on the surface, and gradually the black gourd showed signs of melting.

The black gourd finally melted and turned into a mass of liquid, Ren Jian stretched out his palm, and the liquid fell into his palm and merged into his body.

Ren Jian has been in retreat in the valley for two days, and the black gourd, crystal beads, and rusty kitchen knives in the current Yipin ritual utensils are ...... and so on have been refined, and Ren Jian's cultivation is about to reach the peak of the sixth grade.

"Now there are only five-grade yin and yang jade, three red sand stones, three-grade nine-dragon jade cups, and second-grade lamps that have not been refined......" Ren Jian's gaze fell on the rock, and the four magic weapons were placed there.

After resting for a while and recovering some of his spirits, Ren Jian's hands quickly punched out the magic seal again, and the afterimages were dragged up in the void, and the second-grade lamp slowly vibrate, as if it was dragged up by an invisible force, and finally suspended in the air in front of Ren Jian.

Two more days have passed, and the three pieces of red sand stone, the Nine Dragons Jade Cup, and the lamp have all been refined, refining the energy devoured by these magic weapons, not only allowing Ren Jian's cultivation to reach the peak of the sixth grade, but also sealing half of the cultivation, Ren Jian is ready to breathe for a long time, and his body will return to its peak state, and then refine the five-grade yin and yang jade to sprint to the seventh grade.

It is a hurdle for the sixth grade to break through the seventh grade, but once the breakthrough strength will advance by leaps and bounds, fortunately, Professor Liu got the five-grade yin and yang jade, otherwise Ren Jian really has no confidence to break through the bottleneck.

After pranayama for a long time, Ren Jian had already returned to his peak state, opened his eyes and stared at the yin and yang jade on the rock, and took a deep breath to run the Devouring Smelting Technique. Yin Yang Jade is a fifth-grade grade, and it is quite difficult to refine, ten times more difficult than refining a four-grade red sand stone.

It took two days for Ren Jian to completely refine the Yin Yang Jade, and after absorbing the energy of the Yin Yang Jade, Ren Jian was shocked. The energy in his body faintly seemed to be showing signs of rioting, and when Ren Jian saw this, he hurriedly ran the refining weapon and began to sprint to the bottleneck of the body of the six-grade magic weapon.

"The mana is not enough!" Seeing this, Ren Jian unlocked the seal again, releasing half of the mana of the seal, Ren Jian successfully broke through the bottleneck, and at the moment of breaking through the bottleneck, the body alternated between hot and cold, and the heart-rending pain sprinted to the nerves in his head, and Ren Jian's face suddenly turned pale. trembling violently, Ren Jian still gritted his teeth and persisted.

In fact, what Ren Jian didn't know was that the reason why every breakthrough was unbearable was because the body was transforming, and once it was completely transformed into the body of the breakthrough treasure, there would be no such pain in the breakthrough.

At that time, Ren Jian will be able to truly avoid vulgarity, instead of being like now, although he can go without food for two months. But eating means that he is still classified as a "person", because his body has not yet been completely transformed into a magic weapon.

Ren Jian cultivated the Mutation Refiner Technique. No one has ever cultivated before, and the road in the future needs to be explored by Ren Jian himself, after all, the refining technique is not for people to cultivate, and no one in the cultivation world is willing to put aside the cultivation of the true cultivation method without cultivating, to cultivate this kind of refining technique that is nine deaths and one life.

Ren Jianneng succeeded in cultivating the refining technique, which made the refining technique abnormal, which was luck. This is not replicable, if you ask people to cultivate again, it is okay if the cultivation is not successful, but I am afraid that not only will the cultivation not only be unsuccessful, but will go mad and die.

"Boom!" thunder sounded in my ears. The severe pain in his body slowly subsided, and Ren Jian knew that the breakthrough was successful, and after breaking through the body of the seven-grade magic weapon, Ren Jian's strength increased more than three times, and his strength broke through the terrifying power of the thirty dragons.

At the same time, there was a change in the dantian in Ren Jian's body, an illusory furnace tripod was formed, and the furnace was surrounded by a flame of mana illusion, and at the same time, a piece of information appeared in Ren Jian's mind, which was information about the dantian illusory furnace, the name of the illusory furnace was called the Heaven and Earth Furnace, and the Heaven and Earth Furnace could also be said to be a kind of supernatural power.

What excites Ren Jian the most is the powerful function of the Heaven and Earth Oven, which can actually smelt all things, that is to say, in the future, Ren Jian does not have to devour magic weapons, he can also obtain energy by devouring other things with aura, and even if he devours magic weapons, he doesn't have to work as hard as before.

In the past, Ren Jian's devouring magic weapon still needed to be refined by himself, and then devoured the liquid into energy, but now there is no need to be so troublesome, Ren Jian can directly swallow it in his stomach and smelt it by the Heaven and Earth Oven, and the speed of the Heaven and Earth Oven smelting is a hundred times and a thousand times that of casting the Devouring Smelting Technique.

"Okay, good, heaven and earth oven, haha......" As he browsed the information in his mind, Ren Jian was ecstatic, of course! At present, the heaven and earth oven can't smelt all things, after all, now it's just a phantom in the dantian, and only by condensing the phantom into an entity, the heaven and earth oven can be considered a great success.

However, even if it is an illusory shadow, the smelting speed is also a hundred times and a thousand times that of the Devouring Smelting Technique, and now even if it is a treasure weapon, Ren Jian can smelt it and devour it for his own use, which shows how powerful the Heaven and Earth Oven is.

Ren Jian really wanted to find a magic weapon to try the power of the heaven and earth oven, but unfortunately there was only one furnace ding left on his body at present, and Ren Jian was still ready to keep the alchemy, but when he thought of breaking through the seventh grade, he needed so many magic weapons, so wouldn't there be more magic weapons needed to break through the eighth and ninth grades? Thinking of this, Ren Jian couldn't laugh a little.

"It's time to get out of the customs...... Ren Jian stood up, shook his head and no longer thought about the upset things, with the psychic jade card, as long as there are magic weapons on the earth, Ren Jian believes that he can find them, and as long as the heaven and earth oven is condensed into an entity, then all things can be smelted, and when the time comes, it is not necessary to devour magic weapons, but also to devour other things with aura, and there is no need to be controlled everywhere like now, after all, the magic weapons on the earth are limited.

Out of the valley Ren Jian continued to go deep into the Shenlong Frame, the Shenlong Frame used to be an ocean, and it had not been developed for tens of thousands of years, there must be a lot of good things in it, Ren Jian did not seek to find a magic weapon, as long as he could find one or two refining materials, he would be satisfied.

The Shenlongjia Mountains are endless, the clouds and mist are shrouded, and the mountain roads are rugged, but this is difficult to defeat Ren Jian, after breaking through the body of the seven-grade magic weapon, Ren Jian's speed has also increased greatly, and one step out is thirty meters, he is like a legendary martial arts master, galloping in the primeval forest.

After running for a day in a row, Ren Jian has now come to the deepest part of the Shenlong Frame, which is shrouded in clouds and mist all year round, even with Ren Jian's eyesight, he can't see the scenery ten meters away, and the magnetic field here is weird, the compass will also lose its effect, if it is an ordinary person, it will definitely not be able to go out. (To be continued......)
