The fire in the Imperial Dragon Furnace was burning so fiercely, reflecting on Yin Teng's face, bright and uncertain. Yin Teng took all this into his eyes, and an inexplicable sadness rose from the bottom of his heart, he knew that his current self might only exist in a memory, and the source of this memory might be from the Dragon Calling Bell, or from the Imperial Dragon Furnace in front of him.

But the memory was so real! He could only watch, but he could do nothing......

Yin Teng was in the space of an underground palace at the moment, and the flames in the Imperial Dragon Furnace were burning endlessly as if they were eternal, and they didn't know when they would be extinguished. Although he couldn't see what the situation of the Qiankun Seal and the Divine Soul of the Seven Saints of Su Yuan was in the Imperial Dragon Furnace, with the ground as the boundary, he could clearly see that the outside world was undergoing earth-shaking changes!

Everything in the space around him, except for the refining fire in the Imperial Dragon Furnace in front of Yin Teng, was jumping, including Yin Teng, as if it was being stilled, but outside this ground, there were earth-shaking changes!

In such a scene, it seems extremely strange, the underground is as quiet as death, but above the ground is like a battle turning stars, the vicissitudes of the sea are flying! As if they are not the same face illusion, like a white horse passing through a gap, a glance for ten thousand years!

Such a moving and static space can't help but make Yin Teng have a strong contrast, the furnace fire refining is not only the Suyuan Seven Saints and the Qiankun Seal inside, but also more like the time in the outside world.

At this moment, Yin Teng looked at the ground, the evolution of heaven and earth outside the outside space, perhaps because the underground is the place where the imperial dragon fell, and it is also the reason why the imperial dragon furnace transformed by the imperial dragon's own dragon body continues to refine the Qiankun seal and the seven saints of Suyuan, and its own bones and flesh are also refined at the same time, the imperial dragon furnace is also slowly transformed into a real "furnace", such a "furnace" is not an extremely rare gold and stone, but it is an extremely strong dragon body from the world, and it is the dragon body of the dragon family, as a material voluntarily refined into a "furnace" In the future, once it is born, it will definitely cause a sensation in the entire cultivation world, and the potential is unlimited!

With the continuous refining of the furnace refining fire, a wisp of gray mist will gradually emit from the imperial dragon furnace every once in a while, this mist is extremely thin, but with the accumulation of time, over time, it has condensed under the ground here to form a wisp of invisible qi, although there is only an extremely small wisp, but Yin Teng feels a majestic vitality from this wisp of invisible qi, and there is a kind of majesty, this majesty he has felt on the imperial dragon.

"This wisp of invisible qi is none other than the qi of the dragon vein!"

Yin Teng's eyes showed shock, the qi of the dragon vein, to put it bluntly, is the essence of the dragon's qi, as the saying goes: "people live a breath", qi is a little life of the gods, not naturally generated, it needs to be cultivated over the years, stimulated, maintained. It is the source of life and at the same time a source of strength. If life is weak, it will inevitably be exhausted, and if life is vigorous, it will be vigorous.

And the same is true of the dragon, this dragon vein qi is a kind of manifestation of the dragon's strong vitality, it contains the dragon emperor's life, strength, cultivation, and even luck! The dragon has a spirit, so the qi also has a spirit! And it must also be mixed with a trace of the breath of the Seven Sages of the Refining Element Yuan and the Qiankun Seal, which must have extraordinary creative skills.

And when this dragon vein qi was formed, three thousand years had passed since the day of the fall of the imperial dragon! In the past 3,000 years, a rudimentary mountain range like a dragon has been formed on the ground here!

If the mountain is not high, there is a fairy name, the water is not deep, and there is a dragon.

The formation of the qi of this dragon vein overflowed to the outside world, which actually made the external geology here gradually change, and at the same time made the aura of heaven and earth become different, and even made some animals that originally lived here also inexplicably affected, and their bodies underwent inexplicable mutations, becoming extremely strong, not to mention, there was a faint agility in the eyes, obviously some spiritual wisdom was at the beginning. The most obvious of these is a carp in the river.

This carp was originally no different from ordinary carp, and it was blue all over. But under the influence of the dragon vein qi, it began to change from the head, the skull slowly mutated into a bit of a dragon's head, the corners of the mouth even gave birth to whiskers, and finally even the original cyan scales would slowly transition into gold, and the body was also extremely strong, and it was full of spirituality!

"That's the dragon fish"!

The process of turning a green carp into a dragon fish in the outside world is extremely slow, and it takes thousands of years, but from the perspective of Yinteng, it is like a fleeting moment...... Looking at this scene of changes, Yin Teng recognized at a glance that this fish was the dragon fish he had come into contact with when he participated in the 'Dragon Gate Trial' before, and his eyes were full of shock.

With the rapid change of the outside world, time flies, and the fire in the Imperial Dragon Furnace is constantly refining, and every hundred years it emits a wisp of gray mist, which is constantly fused with the previous dragon vein qi, and gradually this dragon vein qi has become extremely majestic......

In the blink of an eye, three thousand years have passed in the outside world, and the Imperial Dragon Furnace at this moment no longer emits gray mist, but the dragon vein qi is centered on the Imperial Dragon Furnace and permeates this place for dozens of miles! Yin Teng looked at this dragon vein qi and faintly felt that something seemed to be brewing in this dragon vein qi......

Sure enough, on a certain day, the majestic dragon vein qi that stretched for dozens of miles underground rolled and contracted violently without warning, and with the continuous contraction of the dragon vein qi, the change of heaven and earth brought gusts of wind and thunder, becoming more and more condensed!

Ten miles!

One mile!

Baizhang!

One foot!

In the process of shrinking and solidifying again and again, the color of the dragon vein qi that was originally gray gradually became deeper, and the more pure dragon vein qi continued to shrink inward, and those dragon vein qi that seemed to be impure and impurities overflowed to the earth and was absorbed by the earth.

Gradually, the qi of this dragon vein became smaller and smaller, but the color on it became darker and darker, and in the end, it turned into pitch black, only one zhang long. On the ground in the outside world, the rudimentary mountain range that had formed a dragon-like shape before was no longer a prototype, but was actually hundreds of feet tall and stretched for hundreds of miles!

The dragon vein qi that had turned black seemed to have used most of its strength due to this contraction, as if it had injured its vitality, and it became extremely heavy. Gathering in one place staggeringly, it gradually fell silent, and finally formed a black giant egg two meters high and one meter wide! This giant egg looked inconspicuous at first glance, like an ovoid stone.

Seeing this scene, Yin Teng looked at the black stone egg with a thoughtful look in his eyes.

After that, another three thousand years passed in the outside world, and during these three thousand years, the refining fire in the Imperial Dragon Furnace was still burning, but in Yin Teng's eyes, this refining fire was much smaller than the beginning!

The outside world has undergone the vicissitudes of life, and in the nine thousand years before and after, the region seems to have absorbed the energy and luck of the dragon veins that overflowed before. Five cloud-shrouded, continuous and earth-shattering peaks gradually rose, among which there was one of the most majestic peaks, which looked like the head of the ancient dragon in the legend, and the remaining four peaks, like the four dragon claws of the dragon, stood in the east, west, south and north directions.

Starting from the highest dragon head peak, the mountain range that was extended is closely connected with the rest of the dragon claw four peaks, and there is no end in sight, if you look down from the sky, this is still the original prototype, and the entire mountain range is clearly an entrenched dragon!
