It's just a Dan furnace! Even if it is ten, hundred, the Kunshan faction gritted its teeth and smashed the pot to sell iron, and it had to forge this Dan furnace!

Qingyun Daogu screamed, "What did you say? This thing is called the Wandan Furnace, and it will automatically absorb the aura of heaven and earth to evolve like a legendary genius earth treasure? ”

The huge cave suddenly became quiet, and even the Baoyun Dao people who were jumping at the entrance of the cave turned their bodies in a daze and looked at this side.

Absorb the aura of heaven and earth to evolve yourself, this is the function of those legendary ancient treasures! With the level of Baoyun Dao refining weapons, he can refine medium-grade treasures at most now, if the medium-grade treasures can automatically absorb the aura of heaven and earth and evolve slowly, then ...... What if this function was amplified into the flying swords and magic weapons used by the disciples of the Kunshan Sect?

Zhang Yuan nodded lightly, he had already prepared, and took out a thick stack of paper from the bracelet. "Here, it is the 'Divine Concentration Array' obtained by the Divine Medicine Patriarch who comprehended a fragment of a magic weapon at a certain secret place in the Upper Immortal Realm Ruins, and refined the Divine Concentration Array into the core of the magic weapon, then the magic weapon can automatically absorb the aura of heaven and earth, and slowly improve its quality."

Zhang Yuan gently put the thick stack of paper into the trembling hands of the Thundercloud Daoist, and said in a low voice: "However, the Condensing Array can only absorb and refine the aura, but it can't change the material of the magic weapon itself, so the materials I listed for forging the Wandan Furnace chose the best material." ”

Thundercloud Daoist instinctively stuffed the thick stack of paper into his sleeve, and then he realized that his movements were so indecent, and he couldn't help but laugh out loud in embarrassment.

However, no one laughed in the cave. Even Qingcao knew dimly that if this Condensation Array was really so wonderful, then the flying swords and magic weapons used by the disciples of the Kunshan Sect in the future would slowly improve their level with the passage of time. Don't improve too much, as long as those flying swords and magic weapons are raised by an average of one grade, the strength of the Kunshan faction can soar by several percent!

"This array is too precious." The Thundercloud Daoist took a long breath, looked at Zhang Yuan with a little surprise and smiled bitterly: "Poor Dao is ashamed." ”

Zhang Yuan waved his hand lightly and said lightly: "Needless to say, the predecessors have stored more than 2,000 years in the alchemy Mahayana secret book of this concentrating array, and because it is a formation, no one has ever been interested in it. The younger generation has also suffered a big change recently, so I sorted out the alchemy Mahayana cheats I had written, and then I found this concentrating formation. ”

Zhang Yuan smiled lightly and nodded: "In the alchemy Mahayana secret book, the younger generations of the Dan Dao technique dare not leak in the slightest. However, some of the gadgets left by the ancestors that have nothing to do with Dan Dao will be slowly sorted out by the younger generations and handed over to Lei Yun to teach. Zhang Yuan knew that he had something to ask for from the other party, and he had to give the other party enough sweetness.

The Thundercloud Daoist hurriedly waved his hand and said, "This, this, absolutely not!" Saying that, but the heart of the Thundercloud Dao people beat violently again. Zhang Yuan just came to Kunshan to send less than a day's effort, and then he sacrificed the inestimable value of the Concentration Array, God knows what good things he will toss out after carefully sorting out it for a while? These are all good things that can greatly enhance the potential power of the Kunshan faction! As for the Danshu of the Hundred Herb Sect, the Kunshan faction was not greedy for this in the first place! But these wonderful methods are really ...... This one made his heart flutter.

The conditions given by Zhang Yuan could not be rejected by the Kunshan faction, and the Wandan furnace, the largest and most precious material ever consumed in the history of the cultivation world, but the finished product that was refined may be the lowest wonderful treasure, began to be forged with the full strength of the Kunshan faction.

The red light on the lava crater converged, and all the heat gushing out of the ground was concentrated in the huge forging cave by the formation. Led by the Baoyun Dao people, he led the Kunshan Sect to join forces with nine hundred and eighty-one elders who had experience in refining weapons, and eighty-two refining masters, together with nearly a thousand other great and small old Daoists, devoted themselves to the refining project of this unprecedented huge Dan furnace.

The lava crater truly became a smelting peak, and the huge amount of fire aura gushing out of the boundless magma sea underground turned into raging flames and poured into the forging cave, and the raging purple flames rose into the sky, and too much fire was absorbed by the formation, gushing out from the mountain indiscriminately. The whole body of the lava crater burned red, and a purple flame up to 100 meters thick enveloped the mountain, and the heat wave rolled out, so that no ordinary birds and beasts dared to stay within a radius of 100 miles.

Zhang Yuan stood on the Fire Refining Sword, looking at the lava crater shrouded in flames in a daze, feeling the boundless heat wave, without sorrow or joy in his heart, and entering a kind of enlightenment of the Great Dao. The lava crater in front of you is on fire.

Zhang Yuan was so close to the lava crater that the rising flames were even burning to his feet. The heat burned his body, and there was a trace of spiritual energy transformed by lotus seeds in his body that was constantly tumbling out, and after the transformation of fire, it merged into his body. The golden pill in the dantian greedily devoured the pure fire aura of the outside world, and the purple light on the golden pill flickered, and a trace of thunder and fire was steaming enthusiastically.

The Heavenly Punishment Divine Thunder that tightly encased Jin Dan in the center was also excited, and a thumb-sized cyan phantom suddenly appeared on the Heavenly Punishment Divine Thunder, this spirit beast incarnated by the Heavenly Punishment Divine Thunder swam around a few times, and suddenly opened its big mouth and sucked hard at the outside world, Zhang Yuan's dantian shrank, and an invisible huge suction force surged out from Zhang Yuan's dantian.

'Whew', a whirlwind suddenly rolled up on the lava crater, and the whirlwind enveloped Zhang Yuan's body, rolling up the fiery aura dozens of meters away around Zhang Yuan's body, and bubbling into Zhang Yuan's body.

"Wonderful, Zhang Yuan Xiaoyou is really a good cultivator." Lei Yun, who was standing on a white cloud a few miles away, smiled and said: "With such a fire, if we don't need to protect our body with the fire avoidance spirit technique, we have to stand here to endure that heat, he can actually breathe and cultivate under such flames, and he is really a genius." ”

The flames on the lava crater burned for ninety-nine and eighty-one days. Zhang Yuan was suspended above the sea of fire, nourished by the pure and dense fire aura for eighty-one days. The mountain wind swept by, and his long hair flew away, and the strands of hair rubbed against each other, and from time to time there flashed wisps of tiny fire. The robe on his body had turned into green smoke and drifted away, and a layer of red light faintly floated on his slightly thin body, like an iron ingot that had just been taken out of the furnace. There was a faint flash of thunder in his pupils, and a very thin wisp of purple gold fire wandered rapidly in his pupils.

At this time, Zhang Yuan's Jin Dan was not only restored, but also better than before. After many days of cultivation, with the help of the devouring ability of the Heavenly Punishment God Thunder's furious rage, Zhang Yuan's cultivation not only recovered to his previous peak state, but also greatly improved, and the condensation and refinement purity of the true yuan were not comparable to before.

And this time, the Heavenly Punishment God Thunder was also very cooperative, and instead of plundering Zhang Yuan's true yuan that had just recovered, it also carefully washed and refined his golden pill for Zhang Yuan. I don't know what the origin of this Heavenly Punishment God Thunder is, it is so wonderful that it is surprising, and Zhang Yuan's Jindan has been successfully refined, so that although Zhang Yuan only has the cultivation of Jindan in the early stage, the quality of Jindan is not weaker than that of the monks in the later stage of Jindan.

The purple-gold mutated Heavenly Thunder Extreme Fire True Yuan was surging in the dantian, and the Jin Dan kept spitting out the tumbling True Yuan, and the light on the Jin Dan became more and more dazzling, and a layer of purple gold fire and thunder qi was entangled around the Jin Dan, setting off its extraordinarily smart and bright.

Zhang Yuan looked up to the sky and let out a long roar, the howl was like the roar of a long dragon, shaking the sea of fire below.

He clasped his hands together, slowly sealed the seal, the flames all over his body disappeared, and he took out a spare set of Taoist robes from the bracelet and quickly put them on. Glancing back at Lei Yun and the others standing on the white clouds in the distance, Zhang Yuan slowly flew over with the Imperial Fire Refining Sword, bowed to the Lei Yun Dao people, and said lightly: "The junior is rude." ”

The Thundercloud Daoist smiled lightly, shook his head and said, "It's okay, it's okay, these days, Zhang Yuan Xiaoyou seems to have entered the realm of enlightenment, and his cultivation should be greatly increased, which is a good thing." Zhang Yuan nodded, came to the side of the Thundercloud Daoist with his sword light, and looked at the lava crater with his hands behind his back, but stopped talking.
