There are countless caves on the main peak of Iron Sword Peak, where core disciples and elders in the peak are all cultivating, and Shan Huayuan's cave is located under the Tianchi, the top of the main peak.

Wuxin had already entered this place several times, and each time he couldn't help frowning, because Master's cave mansion could be described as 'dirty'. The aura here is rich, wrapped with green vines, and the thick green green vine leaves are like his robes, stained and dotted, like a human face covered with pockmarks. The stone walls were never smoothed and were called 'natural', in his words. All kinds of dust fell all around, and even on the stone bed, there was an obvious big letter. I can't imagine that Master sleeps in the same position every time he leans on his back and sleeps in the same position.

If you want to say the cleanest, I'm afraid that only the picture of the jade girl flying on the stone wall hangs on it. It was the portrait of Yu Qinghan, the peak master of Jade Sword Peak.

"Master, can you sometimes clean up a little, but you are also the peak master!"

Hearing the disciple's words, Shan Huayuan pouted and said, "I want you to take care of it!"

Wuxin shook his head and followed the master inside. Only then did he know that Shan Huayuan had not relied on the common refining furnace on the main peak.

Enter the cave, go deeper, after a few bends, appear on the edge of the stone cliff, the terrain is like 'dragon opening its mouth', the two stand in the dragon's mouth, the clear moon hangs high, a little cold. There was a sound of 'clanging' in my ears, and I looked at the sound and saw a half-human furnace ding appear outside the dragon's mouth, and then go out for half a minute and it would fall off the cliff. The furnace is purple in color, and eight dragons are engraved on it, with the dragon's head facing outward, looking up to the sky and roaring. Under the stove, only one piece of wood is burned, the flame is not strong, but the scorching feeling is beyond the usual, and you can't get close to it without intention. The sound of 'clanging' came from the furnace.

There is no difference between the outside of the refining furnace and the alchemy furnace, but the inside is completely different. When the raw materials are burned red by the flames, through the open dragon's mouth outside the furnace, the 'true qi' is used to control the mechanism inside to beat, hammer to a certain extent, and then inject water from the dragon's mouth, and then continue to burn, continue to beat, until after a hundred or a thousand refinements, the sword type is formed.

"Master, what kind of fire is this?" Wuxin asked.

"It's not as good as the true fire of Samadhi, but it's not much worse. This is Xuanmu, which your senior brother obtained from Wushan and gave to you. ”

"Senior Brother Qingyou?"

"Yes, he's thinking about you. ”

"Then I have to thank him. ”

"Of course, what is refined by Xuanmu is naturally the best product. ”

"Senior brother has been to Wushan?"

"Yes, you want to go too, don't think about it yet, unless you have at least reached the Jindan realm!"

"Anyway, I'll go sooner or later, I have a lot of fate there!"

Shan Huayuan was stunned for a moment, and changed the topic and said: "You can also handle this sword, you can be tempered every day, and after another seven hundred and forty-nine days, today is the fiftieth, in order to achieve one hundred refinements." You're just about to take the last step of sacrificing the sword, are you ready?"

Hearing this, my heart beat faster suddenly, I had been waiting for it for so long, but at this time, it was a little... Fear: Fear that this artifact will not live up to expectations.

"What, don't you plan to open the furnace?" Shan Huayuan quipped.

Unintentionally asked, "How many more clicks do you need?"

"Nine more!"

Unintentionally stunned, calming down, his heart beating with the sound of 'clanging' from the furnace. Standing outside the scorching air waves, secretly operating the power in the dantian, silently counting: "Nine, eight, seven, six, five, four......"

"Oh~~"

The Xuanmu under the furnace was burned out, and a deep and leisurely sound came from the refining furnace, and he suddenly opened his eyes, his heart paused for half a second, the blood was rolling, and his right hand was like a sword, and he swung it out violently, and a drop of blood flew out from his fingers. Time and space seem to freeze frame.

Seeing this, Shan Huayuan appeared on the side of the furnace, and a force swung out, and a trace of smoke swayed from the furnace.

Rumble!

The red sword body flew out of the furnace and hung above it. At the same time, the heartless blood flew into the sword body! The sound of 'Zizi' sounded, and the heart's blood was melted by the red-hot sword body.

Rumble!

The flying sword flew out of the dragon's mouth, and a rainbow light shot straight into the sky, reflecting the clear moon in the distance, and the entire sky turned red. The rainbow light that soared into the sky stirred the clouds, creating a huge whirlpool. The whirlpool was surging, and dark clouds swept in the distance.

In the rainbow light, you can clearly see the dragon looking up to the sky and groaning, and the tiger roaring loudly. After a while, I saw a dragon and a tiger fighting in the red light, straight into the sky.

Powerful movements echoed in the Sword Yu Sect, and the sound of those beasts on the mountain could be heard worshipping excitedly.

Thundered!

Dark clouds swept in, thunder roared, lightning shone brightly, and everyone who heard it was shocked.

"This ......" Obviously, this kind of movement was something Shan Huayuan didn't expect, looking at the long sword suspended in the air emitting red light, he didn't know what to say.

Wuxin is also shocked, more excited, the flying sword that can attract the vision of heaven and earth is naturally not ordinary. But he was a little worried, because the thunder and lightning in the air had already struck the red sword.

At this moment, the flying sword soared into the sky, taking the initiative to meet the dense thunder and lightning under the red and black clouds! The rainbow flashed, as swift as a dragon and as heavy as a tiger. Surrounded by sharp edges, it exudes an iron-clad aura like a human being.

The rumble was mixed with the roar of the tiger and the roar of the dragon. The clear moon turned into a red moon.

He inadvertently counted the number of thunders and lightning strikes in the air, until the ninety-ninth thunderbolt struck, the dark clouds receded, the red light disappeared, and the roar of the dragon and tiger was hidden.

Wuxin's heart suddenly tightened, his hands waved, he recited the magic trick, and said, "Return!"

Shout!

The flying sword was lightless, and it appeared in front of Wuxin in an instant, and its body was scorched black, and cracks appeared.

"The thunder tribulation that was actually triggered!" Shan Huayuan sighed.

Wuxin's left hand held the charred black hilt, and his right hand slashed across the sword body in the shape of a sword, and the charred black color on the sword body suddenly fell off along the cracks, revealing the cold and smooth sword body. The spine of the sword is straight and straight, and the two edges are extremely sharp. Qing Yue shrouded again, standing outside the dragon's mouth, unintentionally looking at this sword, and couldn't help but sigh: "It's really 'the sword comes out of the dragon, and the snowflakes shine on the hibiscus'." ”

Wuxin looked at the hilt of the sword again, and found that the junction between the hilt and the body of the sword was inlaid with a red spar, and he looked at Shan Huayuan with suspicious eyes, and said, "Master, what is this?"

"This is something inside the Dragon and Tiger Stone, and it seems that it should be the Dragon and Tiger Spirit inside. Shan Huayuan replied, and when he saw this sword with his heart, a trace of greed actually rose. However, it was quickly controlled.

Unintentionally waved it twice, and there was a buzzing sound, which was really overjoyed.

"Let's see if you can cultivate the dantian!" Shan Huayuan said, first, this sword is best not exposed, it is easy to make people greedy, and second, the dantian cultivation can make it cooperate with Wuxin to the best state as soon as possible.

Unintentionally run the trick, and said: "Collect!"

The sword was only suspended in the air, but it could not be included in the dantian.

"It seems that it will take a long time for you to be able to drive here as you like!" Shan Huayuan said, walking towards the furnace ding. He took out the scabbard from the furnace, threw it unintentionally, and said, "Let's carry it!"

Unintentionally took it, looked at the scabbard, the scabbard was black, one side carved dragon, the other side carved tiger, the sword into the scabbard, and his face showed excitement.

"It's much higher than expected, thank you, master!"

Shan Huayuan smiled, touched his beard, took off the tiger skin wine jug on his waist, took two sips, and said leisurely: "No, I am out of the dust, and I look down on merit and fame!"

Unintentionally, he grabbed the wine jug, took two sips, and said, "Okay, master, why don't you give it a name?"

"This sword, after all, is your own, take it yourself!"

Wuxin thought about it and said: "This sword is in one place, the red light is soaring to the sky, it is better to call it 'Tianhong'!"

"Rainbow?" Shan Huayuan thought for a while and said, "Very good, let's call it Rainbow!" However, when Rainbow comes out, the thunder is coming, whether it is a curse or a blessing, you have to accept it." ”

Wuxin said: "Yes!" said and looked at the scabbard in his hand again, and read: "Is it okay to call you Tianhong?"

The sword body shook twice in the scabbard, and he unintentionally played with it, and said, "Come out, Rainbow!"

Shout!

The rainbow was instantly unsheathed, surrounding the heartless body.

Seeing this, Shan Huayuan walked into the cave house leisurely and said to Wuxin: "Go to Tianchi to see your immortality!"

I didn't think about it for more than a month, and I didn't know what happened to me now.

Thinking so, he retracted the rainbow and walked through the cave, he saw Shan Huayuan lying on the stone bed in a large shape, and there were still undried wine stains on his beard. looked at the situation in the cave, shook his head, and sighed: "When will I repair the edges." ”

"Look at yourself, your hair is fluffy, your eyes are cloudy, don't get out of here!" Shan Huayuan muttered, "What a worry!"

Wuxin looked at his appearance, nodded, and said, "Mistake, what a mistake!"

The billowing smoke in the heavenly pond swayed, and the abundant spiritual energy turned into the tumbling pool water, and he stood on the edge of the heavenly pond without intention, and could hardly see the scene in the pool.

"Wuxin, Wuxian, how are you?" Wuxin shouted towards Tianchi.

There was only a bubbling sound of 'cooing' in the pool.

"Nothing is wrong, nothing is wrong!" Wu Xin shouted a few more words, still no response, but he could feel that nothing had happened to Wu Xin, and he could even hear the sound of its breathing.

Thinking about the Rainbow Sword in his hand, he turned around unintentionally, preparing to return to Xukun Peak and look at the sky, it was almost dawn.

The fog was shrouded, the sky was dark, thinking of the abyss, thinking of the four masters, and the words echoed in my ears - Master, I will come back.

"Master, I will go back, I will bring back all the medicinal materials you need, so that you can repair the injuries in your body!"

At this moment, the sound of 'cooing' in the heavenly pool suddenly became louder, and the viscous aura pool tumbled, as if it was caused by the presence of giant animals.

Roar!

A roar came from the heavenly pool, straight into the sky, the thick aura mist was washed away, and a beam of light descended from the dim sky, and this sound broke through the darkness of dawn.

Wuxin, who was about to turn away, suddenly turned around, but saw a vague figure flashing in the mist, huge. Gradually, the fog dissipated, and I looked up unintentionally, shocked. The fox said suspiciously: "Are you... No Death?"

Roar!

A roar shook the heavens and the earth.
