In the underground dragon veins of Kunlun Mountain.

In the black silence of the underground tunnel, an old man and a young man are slowly walking towards the deepest part.

The old man carried his hands on his back, chanted words in his mouth, shook his head from time to time, and enjoyed himself. It was the Ice and Fire Daoist.

Dugu Feng absorbed the more and more intense and pure innate five elements essence, and felt that the energy contained in the "black hole" in the shape of the maple leaf in his body was more and more, and the veins on the leaves gradually appeared, but at present, it was still faint, and the dragonfly was generally not deeply scarred, and there was no clue.

After absorbing such a high-quality mixed essence, the maple essence has already changed from the pale red at the beginning to the colorful color now, revealing a pearl-like glow from the inside out, as if the maple essence around Dugu Feng is no longer his maple essence, but the bright Milky Way in the sky.

As soon as Dugu Feng's mind moved, a brand-new "maple knife" was condensed: I saw that the knife body was four feet long and two inches wide, as if the whole body was inlaid with colored stone jewelry, and it looked much better than Ling Mengchen's purple glazed knife. After all, it is made of all kinds of essence crystals mixed in it, but the color of the essence crystals is much richer than that of the glass fragments.

Dugu Feng obviously felt that the new maple knife he had condensed at this moment was not just as simple as looking good. Due to the fact that the blade was mixed with various innate five elements essence in it, the hardness of the condensed weapon far exceeded that of the weapon condensed by Dugu Feng with only his own maple essence. It is no exaggeration to say that the maple knife that he has condensed has surpassed the purple glazed knife in terms of texture, hardness, and sharpness.

Dugu Feng weighed the slightly heavy maple knife in his hand, and was quite satisfied, "Presumably my maple knife is now a top-grade magic weapon! Haha This maple essence is really wonderful, with this ever-changing, more and more powerful maple essence as a helper, acting as a magic weapon effect." There is also a magic weapon of Chiyou black blood to defile the opponent, so that the opponent can fight against my eighteen weapons with his bare hands, so that is not at my disposal?"

Dugu Feng's heart was overjoyed, and he suddenly had a lot of thoughts and imagined himself.

Just as I was thinking about it, I suddenly realized that a mantra-like voice that had been chattering in my ears finally stopped. Seeing that Dugu Feng seemed to be absent-minded, the Ice and Fire Daoist said with some anger: "You have all the Heavenly Scroll Mental Method I taught you just now, recite it and let me hear it!"

Dugu Feng turned his head and saw that there was a little girl's angry look on the paralyzed face of the Ice and Fire Daoist at this time, although it looked a little nondescript, but Dugu Feng was not easy to debunk, so he couldn't hold back his laughter and recited loudly the Heavenly Heart Scrolling Method. After a while, I memorized it word for word.

The Ice and Fire Daoist originally saw Dugu Feng being dual-minded and half-hearted. I want to take the opportunity to make him deflated, so that he can criticize and educate, who knows that Dugu Feng's memory is also extraordinary, and he will never forget it, and he will never forget it. The back is good. He no longer made it difficult, and continued to tell Dugu Feng about his own practice of this Heavenly Scroll Heart Method. As for that person's heart scrolling method, which is the most basic introductory heart method, with Dugu Feng's current level of mastery of the power of nature, there really is no need to repeat it.

Dugu Feng secretly suspected that this old man was talking a lot, as if everything he had to say in the past few decades was poured out to Dugu Feng. Dugu Feng carefully discovered that since the black gem on the black stone Heavenly Scepter was left at the entrance of the cave to seal the formation eye, in case Xuanjizi would come in, this Ice and Fire Daoist seemed to be more than ten years old, and some traces of time appeared on his face, especially a black hair, which had gradually turned gray at this time.

Dugu Feng was puzzled in his heart, so he found an Ice and Fire Daoist to break down in his thoughts, and asked at a time when he was far away: "Senior, I see that the black gem on your staff is very magical, I don't know what it is?"

As soon as the Ice and Fire Daoist heard Dugu Feng's question, he realized that he had unconsciously regarded Dugu Feng as his own child just now, and said some "nonsense" that was observant and inquisitive, and hurriedly withdrew his mind to cough lightly, and said: "That black stone is the ancestral treasure of my natural sect, and its original body is a black strange stone that has been in the heavenly galaxy for thousands of years, which already contains miraculous effects, and is contaminated by the aura in the galaxy water, forming a stone containing huge "natural energy". One of my predecessors of the Nature's Sect discovered this stone from the Milky Way, and cut off a piece of it back and forth to the world with his great divine power as a magic weapon for sacrifice. Then it was passed down from generation to generation, and the name was said: "Through the sky." "But it is inevitable that there will be wear and tear in the process of using the sacrifice, and when I come here, it is the size of the boulder that sealed the eye of the formation just now. There is also less and less "natural energy" in it.

The Ice and Fire Daoist looked at the empty staff at the head of the staff in his hand, and continued to add:

"This stone has a very miraculous effect after becoming a magic weapon, it can be turned into a boulder, and it can be inlaid on a walking stick, and it also has the effect of helping the practitioner to maintain his youth forever and prolong his life. At the same time, it can communicate and control the forces of nature, and can establish a new connection between the two forces of nature. Like the same source of fire and ice that you saw before, it is with this stone that I can only use it. ”

Dugu Feng listened carefully, nodding his head in praise from time to time.

"The Milky Way Stone, a small piece has such magical powers! The immortals in the sky don't know how to make good use of it, and they actually appreciate it as a beautiful beauty in the sky! It's really a tyrannical thing, let's wait for me to suck it up and refine my maple essence after I cultivate the Great Dao!"

In the middle of this relaxed conversation, the two unconsciously descended into an underground corridor. The slope has finally calmed down.

Dugu Feng looked at the corridor-shaped cave about one zhang high, like a crystal mine. Everywhere there were huge colorful crystals, each as big as a stone, with different shapes. Some resemble a sword stuck upside down into the ground, some resemble clusters of square, angular low shrubs, some resemble stalactites formed by thousands of water droplets, and some are directly oblate and round, with only a small part exposed.

In the same way, these are all huge "essence crystals", which contain incomparably rich essence energy, and they are several times thicker than the small essence crystals in the tunnel before!

Dugu Feng absorbed a lot of pure essence along the way, but he couldn't close his mouth with joy when he saw this scene.

"There are so many big essence stones, when will I be able to suck them all up......" At this time, Dugu Feng seemed to have come to a huge vault, but unfortunately he was limited in what he could take away, and he couldn't bear to watch this huge mountain of gold being missed by himself like this, so he really imagined that Monkey King would conjure up a thousand of himself, release the maple essence together, and "loot" these huge essence stones to be worthy of himself.

For the first time, Dugu Feng felt a feeling of pale powerlessness sweeping over his limbs, and it was in vain to do anything else except to release more maple essence qi to absorb these huge essence stones!

Dugu Feng was completely immersed in absorbing these huge essence stones, and the Ice and Fire Daoist also studied these boulders that seemed to hide countless natural secrets. Everything is so quiet and peaceful.

Both of them didn't notice at all, in a huge underground pit a hundred zhang away in front of them, a behemoth broke open its blood-red lantern-like eyes, and after a low roar, they saw its body gradually shrink to the size that it could move freely in this corridor, and then quietly, like a tiger and leopard gently approaching its prey, slowly approaching the place where Dugu Feng and the two were located......

And a large number of people and horses with the banner of Tianxingdao are also rushing towards Kunlun Mountain from all directions.

Night will be night, the battle of dawn, is coming
