"Mu Bai, this is our Qingyunmen's sundries warehouse, many metal minerals and spiritual materials collected from the outside world are stored in this warehouse, you can choose three for yourself!" Somewhere in the back mountain, Dao Xuan Zhenren said to Mu Bai with a faint smile.

Mu Bai wanted the Thunder Marrow Dao Xuan Zhenren naturally couldn't get it, so he simply let Mu Bai choose the spirit material minerals by himself, and Dao Xuan Zhenren was deeply proud of his wit.

"Miscellaneous warehouse?" Mu Bai looked at the inconspicuous appearance of the cave door, quite surprised, it didn't appear here in the original book, he thought that Dao Xuan Zhenren would take him to the Phantom Moon Cave Mansion to choose a magic weapon!

But it's normal to think about it, Qingyunmen is one of the three righteous sects in this world, so many disciples have walked the world, and after so many years, they will naturally find all kinds of cherished spiritual materials, mysterious minerals or something, and some of them will naturally be stored in the warehouse.

Mu Bai then stepped into the sundries warehouse, and was surprised to find that the sundries warehouse was unexpectedly large, as if it had hollowed out the entire mountainside.

There are more than a dozen rows of wooden shelves in the warehouse, all of which are made of fine thousand-year-old yellow nanmu, some unknown black and swarthy metal are so rudely placed, and there are also several pieces of jade full of aura that are carefully stored, and so on.

Mu Bai looked around, and he had to recall many things for a long time before he could recognize them, including the deep sea black iron, the red flame golden sand, the Tianshan purple copper, the swamp black jade, etc., although they were cherished, they were much worse than the thunder pith.

At this moment, Mu Bai found a finger-sized crystal in the corner of a shelf, and the starlight in the crystal seemed to be flowing. Seeing it, Mu Bai immediately smiled, he didn't come in vain just for this thing!

If he remembered correctly, this was the legendary Extraterrestrial Diamond, a refining material one level worse than the Thunder Marrow, containing star energy, mysterious and abnormal!

Mu Bai's luck didn't end there, and soon, he saw the fragments of Yin Xuanmu on another shelf! Yin Xuanmu is a magical tree, which only grows in the natural Xuanyin land, has the effect of nourishing the soul and strengthening the soul, and is the favorite treasure of the Demon Sect monks!

And Mu Bai even knew that Yin Xuanmu also had the effect of enhancing the spirituality of magic weapons, which could make it easier for sword cultivators to reach the realm of human and sword unity!

With the Extraterrestrial Diamond and Yin Xuanmu, Mu Bai was very interested, looking forward to getting another good thing, but this time he didn't get his wish, and there was nothing good for him to see!

"By the way, does my copying talent have any effect on these heaven and earth spiritual materials?" Suddenly, Mu Bai had an idea, and this idea popped up in his mind, and then he couldn't go away anymore.

"It should ...... It doesn't work, does it?! Mu Bai denied it in his heart, but the copying talent opened up prettyly, and then ...... He was shocked!

"Hey, my copying talent actually works on corpses?" Mu Bai looked at the only thing in the entire warehouse that had talent information, and his heart was full of surprise!

It was a piece of amber that wasn't outstanding, and in the amber was an ugly-looking bug! If he didn't have the talent of copying, Mu Bai would never have thought that in this inconspicuous piece of amber, there would actually be a small ancient earthworm condensed!

[Ancient Worm]: Ancient earthworm

[Bloodline Talent]: Spirit Level (Copyable)

[Regeneration Talent]: Spirit Level (Replicable)

[Mining Talent]: Top (Copyable)

[Earth Talent]: Top (Copyable)

This turned out to be a Tiangu earthworm from the ancient era, wrapped in resin from the ancient era, and has been preserved to this day!

"Hahaha, today is really my lucky day!" Mu Bai's face was full of joy, to him, compared to several other things, the Heavenly Ancient Earthworm was simply the gap between heaven and earth!

From the Heavenly Ancient Earthworm, he can not only copy the spirit-level regeneration talent, but even the top-level earth-based talent, which is simply one for two!

"Anyway, there are a lot of amber on the blue star, can I ...... too?"

At this moment, Mu Bai had the urge to return to Blue Star immediately!

After more than ten minutes, Mu Bai finally calmed down, walked out of the sundries warehouse with a smile on his face, and bowed to Daoxuan Zhenren and said with a smile: "The head of the real person, I have already chosen!" As he spoke, he stretched out his hands, allowing Dao Xuan Zhenren to see the Extraterrestrial Diamond, Yin Xuanmu, and Heavenly Ancient Earthworm Amber.

Dao Xuan Zhenren looked at the three items and said in surprise: "You can find this Extraterrestrial Diamond from the warehouse, it seems that you not only have cultivated far beyond your peers, but you are also extraordinary!" ”

Mu Bai nodded and smiled: "It's all luck!" When I was bored on Dazhu Peak, I liked to watch the codex left by the ancestors on Dazhu Peak and recognized this extraterrestrial diamond! ”

Dao Xuan Zhenren looked at Mu Bai with approval and regret, this junior likes it more and more, but unfortunately, it's not from the Nagato line......

After returning from Tongtian Peak, Mu Bai immediately became busy, he wanted to take out the Tiangu earthworm in the amber completely!

Mu Bai was a little worried, afraid that the Heavenly Ancient Earthworm would not last for two months, if the Heavenly Ancient Earthworm corpse was exposed to the air like this, would it be directly oxidized?! After all, this is a creature of the ancient times that is extremely cherished!

Later, Mu Bai had an idea and thought of resin, which is the same as amber, and after the ancient earthworm was taken out of the amber, it was directly immersed in the resin to prevent further oxidation and mutation.

"It's a pity that there is no formalin, otherwise why bother?!" Mu Bai secretly complained!

It took Mu Bai half a month to collect enough resin, and then, on a certain day in a certain year, month, and year, Mu Bai cut open the piece of amber with the most rigorous attitude, and put the Tiangu earthworm into the resin with lightning speed, completing this great moment in the world of Zhuxian!

This is a small step for mankind and a big leap for the civilization of the world of Zhuxian!

"Regenerate talents, copy success!" Then, the spirit-level regeneration talent of the Heavenly Ancient Earthworm, which Mu Bai valued the most, was copied into Mu Bai's hands! The other two talents, just wait for the time to come, and then copy.

However, at this moment, Mu Bai found that the Tiangu earthworm soaked in resin began to turn black, and soon changed from a small black dot to completely black, and then lost all the breath of life!

When Mu Bai used the copy talent to observe again, there was no talent information left!

At this moment, Mu Bai was dumbfounded!

WTF？！

This seems to be ...... Oxidation?!

Could it be ...... The Heavenly Ancient Earthworm is actually not dead? But when I unraveled the amber, I really died?!

The more Mu Bai thought about it, the more he felt that it was possible, and he suddenly felt melancholy, because he thought that his copy genius could be used on corpses.

It took three days for Mu Bai to clean up his mood and fuse the spirit-level regeneration talent.

Fortunately, the ability derived from the spirit-level regeneration talent is very powerful, which gave Mu Bai a big surprise! Mu Baina did his own experiment, and after cutting off a piece of meat on his leg, it quickly grew. Well, cut your finger or something, Mu Bai didn't dare to try to die, in case it would be embarrassing if it took a long time to regenerate.

After the Heavenly Ancient Earthworm was processed, Mu Bai finally shifted his attention to his Thunder Sword upgrade project!

After the Extraterrestrial Diamond and Yin Xuanmu, plus some other metal spirit materials that he had purchased, his Thunder Sword was already hungry and thirsty!

The upgrade work of Lei Ji Sword was in full swing, and when I heard that Mu Bai was going to upgrade Lei Ji Sword, the entire Dazhu Peak was alarmed, and they all turned into melon-eating onlookers, wanting to see the birth of the Nine Heavens Divine Soldier.

Later, even Tian Buyi and his wife couldn't help but come to visit, and after the visit, Comrade Lao Tian also had the idea of upgrading his Red Flame Immortal Sword, but unfortunately he was shy and couldn't even take out a piece of better spiritual material.

So early one morning, Comrade Lao Tian went down the mountain......
