The eight qi who had just entered the huge abyss crypt couldn't help but tremble in the body of the primordial god, excited and afraid.

Roar.. The faint sound of the dragon's groan echoed in the crypt, and the light in the crypt was impressively transformed into a dragon's shape, exuding a strong dragon aura. In this place surrounded by rich dragon energy, there are huge skeletons on the ground that rise and fall like mountains, and from the remaining basin-sized scales, you can vaguely distinguish that they are probably falling dragon bones.

"Is this a dragon cemetery?" was a little surprised and shocked to look at Zhang Huban with a huge dragon corpse, and couldn't help but count it carefully: "One, two... Thirteen, there are the bones of thirteen giant dragons!"

Zhang Huban didn't think that there were only thirteen dragon corpses here, after all, the ancient dragon, that was a powerful existence that could call the wind and rain, had a long lifespan, and it was almost certain that he would cultivate to the Yuan Infant Stage. Under normal circumstances, the ancient dragons who have achieved successful cultivation should have soared, and only those who died by accident would have bones left.

In a small earth, even in ancient times, how many dragons could exist? It is already very rare to be able to leave thirteen dragon corpses.

These dragon corpses have obviously gone through a long time, and they have long been devoid of flesh and blood, and even the skeleton is basically rotten and fragile, leaving only an empty shelf. On the contrary, those dragon scales have basically been preserved, and they still have strong defense, which is a good material for refining weapons.

The thirteen dragon corpses differed in size and aura, the smallest one was only more than ten meters long, and the largest one was almost two or three hundred meters long. The smaller the dragon corpse, the more rotten it becomes.

While observing those dragon corpses on the shore of Zhang Lake, Baqi couldn't help but absorb the dragon qi. This dragon qi is transformed by the essence energy in the dragon's body. Eight Miscellaneous only absorbed a short period of time, absorbing a part of the dragon qi, and the illusory Yuan Shen body looked obviously condensed a lot.

"This dragon qi is really a good thing! If you absorb it like this, it may not take too long to reshape your body, right? It is not impossible to evolve and transform into a real dragon!" Seeing this, Zhang Huban, who was secretly in the road, also took the initiative to absorb the dragon qi in this crypt dragon tomb.

Zhang Hu, who was hanging in the dragon tomb with his eyes closed, absorbed the dragon qi much faster than the eight qi.

Soon, the surrounding area turned into a whirlpool, attracting a large amount of dragon qi to sweep and gather. Zhang Huban's body was like a bottomless pit, frantically absorbing these dragon qi. Slowly, the surface of Zhang Lake's body formed dragon scales, exuding a surging dragon breath.

Time passed slowly, but after half a day's effort, the dragon qi in the dragon tomb was divided by Zhang Huban and Baqi one after another. Most of them were absorbed by Zhang Huban. And even if a small part of the Eight Confusions was absorbed, the figure had obviously become much more staring, and the aura was even stronger, and even the eight heads had grown illusory dragon horns.

"Huh.." After all the dragon qi was absorbed, Zhang Huban noticed that around those dragon corpses, in the cracks of the scattered dragon scales, there were blood-colored grass-like plants, with dragon scale-like fine lines on them, and they all exuded dragon breath.

Zhang Hu, who flew to the ground, picked a blood-colored grass and looked at it, clearly feeling the rich and surging energy in it, and the energy contained in each blood-colored grass was no weaker than the energy contained in a spirit infant pill.

"This grass seems to be. Well, according to the information I received from the Wu Clan's inheritance, it seems that in ancient times, the Dragon Clan fell, and the Blood Dragon Grass was nurtured by the flesh and blood energy of the Dragon Clan's corpse, right? This is the main medicinal material for refining the Blood Dragon Pill! Blood Dragon Pill, that is even more magical than the Spirit Infant Pill and the Dragon Spirit Pill, and it can also easily make the Jindan Monk reach the Yuan Infant Stage!" Zhang Huban, who was muttering to himself, couldn't help but light up when he looked at the blood-colored grass scattered and growing next to those dragon corpses.

Zhang Lake, who picked those blood-colored grasses one by one, counted them carefully, and there were more than 100 plants!

With so many Blood Dragon Grasses, what is the concept? You must know that with the strength of the energy contained in the Blood Dragon Grass, one Blood Dragon Grass, plus some other auxiliary medicines, is enough to refine several Blood Dragon Pills. More than 100 Blood Dragon Grasses, once all of them are refined into Blood Dragon Pills, they are hundreds, which can make hundreds of Jindan Monks become Yuanying Cultivators. In the entire Wudang Sect, there are only nine Jindan monks now, and there are less than a hundred Qi Stage monks.

Once the hundreds of Blood Dragon Pills are refined, plus the more than 100 Bijin Pills obtained by Zhanghu before, it is enough for the Wudang faction to have hundreds of cultivators who have cultivated above the Yuan Infant stage, so that the Wudang faction can truly plug in the wings to take off and become powerful.

"With so much blood dragon grass, it's indeed a big harvest. However, today's harvest is more than that," Zhang Huban muttered to himself, his eyes fell on the dragon skeletons and dragon scales scattered on the ground.

There are many dragon scales, and they have different attributes, because the dragon's cultivation is different during his lifetime, and the materials are also good and bad. But even if it is the most inferior material of dragon scales, it is still no problem to refine medium-grade magic weapons, and most of them can refine high-grade or even top-grade magic weapons. Among them, the dragon scales left by the largest dragon corpse are enough to refine an immortal-level magic weapon.

The point is that the dragon scales on a giant dragon are still a lot of them! These dragon scales alone far exceed the value of all the refining materials that Zhang Huban has collected in the Nanhai Immortal Mansion and the Iga Shrine for tens of thousands of years.

In addition, there are those dragon bones that have not been completely corroded, and basically the remnants of the powerful energy power are the dragon's vertebrae and a section of the bone connected to the vertebrae.

These dragon bones were preserved because the dragon's vertebrae contained the remnants of the dragon's marrow and even a small amount of essence blood.

It is precisely because of the existence of dragon marrow and dragon spirit essence blood that these dragon bones have been nourished, and instead of decaying, they have become more high-quality refining materials.

However, before collecting these dragon bones, Zhang Huban first collected some of the remaining dragon spirit blood. Although the remaining dragon spirit essence blood is not much, but when added together, there are two or three hundred drops, which is probably a lot more than the small vial of dragon spirit essence blood left by the Western legendary powerhouse Hill Realm Lord that Zhang Huban will get from the family of that Cindy teacher in the West in the future.

It is also worth mentioning the dragon horns and dragon claws left by the thirteen dragon corpses. The dragon horn is also the essence of the dragon family, growing on the skull, connecting the vertebrae, and is also nourished by the essence of the dragon marrow, which is a rare and rare refining material, more precious than dragon scales.

As for the dragon claw, it is the attack weapon of the dragon clan, and the material is even better, and the preciousness is not much worse than the dragon horn, and it is also more precious than the dragon scales.

In a short time, in the entire Crypt Dragon Tomb, only the fragments of the decaying dragon bones remained, and there was no trace of the dragon's remains.

With so many precious materials in hand, Zhang Huban naturally wouldn't put them in the Qiankun ring to take up space. Therefore, he who left Baqi to meditate in this crypt dragon tomb went straight back to the Nanhai Immortal Mansion, took out one of the six best magic weapons obtained in the Nanhai Immortal Mansion before, and began the retreat alchemy and refining.
