The faces of the four masters all changed, and beads of sweat the size of soybeans rolled down their foreheads, sweating one by one. Zhao Jing and I are the closest, and my face is even more red like Guan Gong, but it has increased a little bit of majesty.

The four of them are either cultivators, or the pinnacle of contemporary martial arts, and half a foot has stepped into the threshold of 'entering the Tao with martial arts', which is said to have long been a cultivation that is not invaded by cold and heat, but in front of this fire that is still hidden at first glance and half in the clouds, it has become the same as mortals, and they just want to find an air-conditioned room to hide in.

However, none of the four really wanted to leave, and their eyes widened, for fear of missing Xu Zhenren's sword refining process.

Among them, Chen Ning's emotion is the deepest, he is famous for his sword, and naturally he also has a lot of experience in the method of sword refining, and it is not an exaggeration to say that he is an expert, but it is a pity that it is one thing to understand the method, and it is another thing to have enough strength, and it is the most regrettable to have a weak heart.

Before Xu Changsheng retreated, he still learned in detail the various theories and methods of sword refining from him, which are the only methods in the secret legends of Taoism. But who knows that what he, the 'teacher' is looking forward to the most, is that he hopes to see Xu Changsheng, a student, refine a high-grade immortal sword!

"Is this the real fire of the lungs? Am I not dreaming? Okay, great!"

Just like the rising sun was born on the sea, the fire color was conceived among the clouds and clouds for a long time, and finally jumped out, and everyone's eyes suddenly shone brightly, with the cultivation of the four people, they actually felt that their eyes were stinging, and they could hardly open them!

The first one to desperately open his eyes was Chen Ning, the furnace of sword refining was his, and the method of sword refining was taught by him, although he did not have the ability to refine the world-famous immortal sword, but is this important? He has now deeply substituted for Xu Changsheng, and has decided that Xu Changsheng's success is his own success.

In front of you is a three-legged furnace tripod, the whole body is black, like iron non-iron, like wood not wood, like stone not stone, this furnace is Chen Ning master door heavy weapon, the history can be traced back to thousands of years, it is said that it has been left in the hands of Buddhism and Taoism two powerful hands, through the blessing of Buddhism and Taoism, there are infinite wonders, and therefore there is a name of 'Sande Xuanji furnace' that seems to be like a Buddha.

It's a pity that this spirit furnace was still used once in the hands of Teacher Chen Ning, refining the 'Qingfeng Sword' he is using now, since it was passed into his hands, it has never been opened, and the difficulty of collecting materials is only one of the reasons, and the biggest difficulty is in the choice of this furnace.

Taoist refining tools can be used in mortal fire, heavenly fire, earth fire, samadhi fire, heavenly fire and samadhi fire are legends, where fire is used the most, but it can only refine some gadgets, coaxing Malatang such a little girl is almost the same, to become a big tool is simply delusional.

Therefore, under the heavenly immortals, the first fire is the earth fire, which is also the true fire of the earth lungs. This fire is hidden in the depths of the earth, with venom magma outside, and burning fire poison inside.

Although the Sande Xuanji Furnace has been blessed and enlightened by countless masters, and it can find the true fire, but if you want to see it safely drawn out, it has to be like a mountain and a sea of mana, Chen Ning is not unmoved, and wants to gather a few masters in the Dao Sect to work together, but in the end, he still retreated, because he was worried that he would not be able to cope with the power of the true fire, and if he made a living disaster, even if he was the head of the Taoist Association, he would be hunted down by cultivators all over the world!

At this moment, I saw that the fire in the Sande furnace was divided into three colors, the first layer was red and yellow like a fire, the inner layer was like an egg white, and the fire color at the innermost core was as dark as a curtain, if you didn't observe carefully, it was almost impossible to detect, Chen Ning was almost crazy, this is the real fire of the lungs that the teacher had barely triggered when he joined forces with the two senior leaders of the monk and the military uniform!

"Om!"

The vowels of heaven and earth drank out again, only to see the clouds and colorful Lan flickering one after another, and erected a layer of shield outside the Sande Xuanji furnace, the four masters suddenly felt the heat disappear, and they all breathed a sigh of relief and looked at it, only to see Xu Changsheng's nose exhaling red and white two breaths, intertwined like a two-color rainbow, one end tied to the lower end of the furnace body, and the other end was penetrated from the endless clouds, and the three-color flames flew into the furnace along this 'rainbow bridge', as if the most brilliant acrobat was juggling, and it was dazzling to see.

"It's really the true fire of the earth lungs, the legendary earth immortal cultivators have the great mana to seduce the earth fire to refine the immortal sword, but even if it is the legendary mainland immortals, not all of them can become a realm on their own, and they also need to use great mana and various magic weapons to prevent the overflow of true fire and create boundless killing. Xu Zhenren is not an earth immortal now, but he is better than an earth immortal, he is really light!"

Xuqing Daoist sighed again and again, he and Chen Ning accompanied Xu Changsheng in retreat for the longest time, and naturally knew that although Xu Changsheng was superhuman, he still failed to completely open up the second vein of Rendu, and he did not become a mainland immortal, and now he was only a half-step earth immortal at most.

However, Xu Changsheng's body divides yin and yang, and the two qi of turbidity communicate with heaven and earth, showing the true element of the red and white poles, and evolving his own fairyland, such a cultivation may not be able to have the legendary earth immortals, in the face of such a demonic genius, he is admiring, and a little envious and jealous, but he feels that after being by Xu Zhenren's side for a long time, I am afraid that the tenacity he has cultivated in the past hundred and ten years will be gradually worn out, and his confidence will be insufficient......

Chen Dingkun and Zhao Jing are both from martial arts, I don't know what the fire is, but there is no pressure, but it is very interesting to watch, the two of them are thinking about what materials Xu Changsheng wants to use to refine the sword, and they saw Xu Changsheng shouting: "Chen Daoyou, borrow you for ten thousand years of stone blue!"

"Xu Zhenren, Wanzai Shiqing has long been tempered into powder, just stay at this moment!"

Chen Ning patted the brocade on his waist, and drew out a blue light that shot directly into the Sande Xuanji furnace, and when it reached the top of the furnace, it scattered into a green cloud, slowly falling into the furnace, continuously passing through two layers of fire color, and reaching the core of the black flame.

Mortals also have great swordsmen such as Ou Yezi, who once passed down the sword refining method, and needed high-quality lime into the furnace to remove impurities, and the Taoist sword refining was much taller, and it was indispensable to sacrifice the immortal sword for ten thousand years of bluestone powder.

"Okay!" Xu Changsheng said yes, and pointed to the top of the Sande Xuanji furnace with his hand, and three fist-sized black substances appeared out of thin air, and fell into the furnace at the same time, first wrapped in cyan clouds, and then fell layer by layer, first softened by the outermost red and yellow fire-colored calcination, and then refined into liquid by the egg-white-colored second-layer flame, countless black impurities were peeled out at a speed visible to the naked eye, incinerated gas, and finally only a liquid that seemed to be transparent, fell into the core black fire.

Xu Changsheng stood up suddenly, and played nine tricks in succession, each of which was a surging mana pouring into the furnace, and the core black fire was violently divided, and after nine consecutive times, the liquid that seemed to be transparent actually atomized into a cloud of silver-white gas, and suddenly rushed out of the furnace, and wanted to flee in all directions.

"Hehe, you are a stubborn stone outside the world, I spent countless efforts and all kinds of precious materials to turn you into a mouthful of pure innate gold, just like your biological parents, but you want to escape, how can there be such a good thing in the world?

Xu Changsheng pointed at this cloud of silver qi and laughed.
