The underground treasure house of Yutianbao, this huge treasure house covering an area of thirty acres is almost half full, stacked with various refining materials in different categories, and many of them are even after buying these things, Hua Tianxiong himself can't tell what the objects are, after all, the world is mysterious, and there are thousands of rare things.

But he is thoughtful enough, he doesn't know the land doesn't mean that his boss doesn't know it, no matter what it is, buy it and save it first.

In this underground treasure house, Chu Yu stayed for two days and two nights, because there was too much hidden in it, even if Chu Yu was able to distinguish the treasure, he could only come leisurely, after all, he entered the treasure house this time to find a few special objects that were not very inconspicuous, so he naturally had to look at them one by one, saving mistakes and omissions.

It took two days and two nights to finally let Chu Yu find the two refining materials he needed, a palm-sized thousand-year-old warm jade, and a three-hundred-year-old Dao Guide Beast one-horn.

Originally, as a refining material for refining Tongling Treasure Jade Land, it is best to choose the Wanzai Wenyu and the Millennium Dao Guide Beast Unicorn, but it is obvious that the above two refining materials are really difficult to find in this era, and it may even not exist at all.

Fortunately, the Tongling Treasure Jade, the strongest magic weapon in the Refining Treasure Pavilion, does not have high requirements for refining materials.

Another key is that the Tongling Treasure Jade cannot be refined without the Five Aggregates True Yuan Fire, and after the refining weapon is condensed, it must be poured into the magic weapon, and the three mysterious compression spirit arrays are the secret techniques of the Refining Treasure Pavilion, that is, this treasure can only be refined by the descendants of the Refining Treasure Pavilion.

Almost rummaged through the entire treasure house, and finally found all the spiritual materials for refining the spiritual treasure jade, Chu Yu also breathed a sigh of relief, since the battle with the eldest grandson, Chu Yu felt that he needed to refine a few more powerful magic weapons on his body, if he fought against others in the future, the dignified Treasure Refining Pavilion Sect Master actually couldn't take out a decent magic weapon, wouldn't it be bad to pass it on to the old faces of the ancestors of the Treasure Refining Pavilion.

But those upper-grade magic weapon refining land is far from the land refining materials that Chu Yu has now can refine the land.

If a problem is found, it must be solved, which has always been the consistent purpose of the Chu Imperial Institute.

For the vast majority of cultivators, searching for heavenly treasures can only rely on chance and luck, but for a master like Chu Yu who can refine the Spiritual Treasure Jade and Earth Refining Treasure, there is no such problem.

As long as the Tongling Treasure Jade is completed, the three rivers and five mountains will go around, and the Lingshan and beautiful rivers will go around, why worry about not starting with high-quality refining materials!

The treasure house is hidden deep in the underground of the Imperial Heavenly Fort, and Chu Yu is also pure, and after finding all the refining materials, he is not in a hurry to go out, so he simply took thirty-six high-grade immortal stones and set up a spirit gathering array - refining treasures on the spot.

Speaking of which, once the Tongling Jade is refined, although the effect is against the sky, its refining process is not complicated.

Now that the refining materials are ready, Chu Yu took the Thousand Pupil Demon Neidan out again, and spent a night to perfectly smelt the two refining materials together, melt them with green flames, and then shape them with red flames, followed by white flames pulling out of the package and going up.

It's time to instill and compress the spiritual position.Now it's the most important key to refining the Tongling Treasure Jade.When the white flame is wrapped.Chu Yu's ten fingers are flying.The divine consciousness is wildly released.The powerful spiritual power is instantly linked to the magic weapon that has just been formed.With each type of spirit array to break the ground, there is a rune with strange brilliance that bursts out from Chu Yudi's fingers, and it is submerged into the forming magic weapon.In an instant, it merges inside.

This process took Chu Yu a full three days and three nights, this is because he now has the strength to almost reach the middle stage of distraction, if it is still the previous Jindan period, it is estimated that it will not be possible to complete it without thirty or fifty days.

After the final spirit array final seal blasted into the forming magic weapon, Chu Yu also breathed a long sigh of relief, and with the slight movement of his divine sense, the Thousand Pupils Demon Inner Dan had already been enveloped in a ball of green flames, and in just a moment, the black Inner Dan had already been burned off the outer layer of hard keratin, revealing the golden light inside.

The next steps are much simpler, but Rao is like this, and it also consumes more than ten hours of Chu Yu's time again.

As the Thousand Pupil Demon Inner Pill smelted into the earth gold juice completely penetrated into the forming magic weapon, Chu Yu finally withdrew his divine sense, and with a wave of his hand, he collected the Five Aggregates True Yuan Fire into the palm of his hand, and there was also a hint of joy in his eyes, "Although the effect may not be comparable to the Tongling Jade that the master refined back then, it is also inferior.

There is a chance to obtain the 10,000-year-old warm jade and the thousand-year-old Dao Guide Beast Horn Dialect, and it is okay to strengthen it again, but it is not easy to refine it to this level now......

With a move of his hand, the final formation of the Tongling Jade flew into Chu Yu's palm, and he looked at it with his palm for a while, and Chu Yu couldn't help laughing, "With you, why worry about having no refining materials available in the future, and ...... With your help, I may be able to recover those top-level magic weapons that I scattered and flew away after the unsuccessful crossing......

Thinking of this, Chu Yu was also moved, you must know that when he crossed the catastrophe, the Great Extinction Five Elements God Thunderbolt bombarded, although his body was completely destroyed, and many of the magic weapons around him were also bombarded into slag, but there were still no less than ten pieces of the top level magic weapons that Chu Yu had at hand to resist this blow, the magic weapons were psychic, after completely losing the master's breath, these ten or so magic weapons flew away, and I don't know where they fell.

You must know that these magic weapons are the strongest magic weapons in the three hundred years of Chu Yu's refining land! Among them, the two magic weapons of the Qingtian Ruler and the Divine Hidden Ring are the most powerful, and these two magic weapons can be said to be the most proud finished products in Chu Yu's three hundred years of refining and treasure making.

Retracting his thoughts, Chu Yu bit the tip of his tongue, turned his palm into a rectangle, and threw a small white jade ball from the four corners of the drum to the spiritual jade, followed by a mouthful of blood spurting out, and then a little divine sense penetrated the jade.

The essence and blood are the guides, and the divine sense is the lock, and now this psychic treasure jade has become a thing that can be used by the only Chu Yu.

Caught the falling Tongling Jade again, and at the same time as Chu Yu entered a true Yuan force, the small white jade balls on the four corners of the Tongling Jade actually lit up two.One flashed with green brilliance.The other was dancing with blue brilliance, it was obvious that the green brilliance was beating faster, and the blue brilliance would only light up every few seconds.

Chu Yu was also a little disappointed, but he was immediately relieved, most of the refining materials in this treasure house were bought and sold in the world, and it was a great thing to be able to induce the excellent and excellent level treasure search spiritual light to light up.

You must know that Chu Yu traveled to many places with the Tongling Treasure Jade, and he only lit up five epic-level treasure search spiritual lights, and once a legendary-level treasure search spiritual light.

Holding the Tongling Treasure Jade in his hand, Chu Yu wandered in the treasure house, whenever the blue light continued to light up, Chu Yu would stop and search for a while, and it didn't take long for him to take a bunch of very good refining materials.

After about a dozen kinds of inducing blue treasure search spiritual light were placed into the Nine Python Ning Bi Bracelet, the shining blue brilliance on the Tongling Jade suddenly dimmed, and after the last two flashes, it was silent.

Then he put his mind on the Nine Python Ning Bi Bracelet, "Last time, I was only cultivating in the early stage of Jindan, and my divine sense was not strong enough to open only one layer of storage space, but now that I have reached the distraction period of cultivation, I should be able to open a few more layers of space to ......."

Thinking of doing it, Chu Yu did not hesitate to do it, just like opening the storage space on the first layer of the Nine Python Ning Bi Bracelet before, under holding his breath, Chu Yu concentrated all his divine consciousness in the center of his eyebrows, until he reached his personal limit, and his divine consciousness suddenly released at the center of his eyebrows.

"Boom"

Chu Yu only felt that his divine consciousness was shocked, and a powerful divine consciousness fluctuation was touched by him, and then he found that his divine consciousness had entered a huge and extraordinary space with all his strength, but the surrounding area was not as empty as the storage space on the first layer of the Nine Python Ning Bi Bracelet.

As far as the eye can see, there are piles of all kinds of bronze weapons, mostly swords and halberds, and there are no less than 10,000 of them roughly scanned.

"What is this?"

Taking a bronze halberd from this space, Chu Yu couldn't help but wonder: "It's neither a magic weapon, nor a refining material, nor a magic weapon that sharpens iron like clay...... It's like an ancient soldier's weapon......"

The Nine Python Ning Bi Bracelet is definitely a magic weapon that only cultivators can use.But what is the use of a cultivator collecting so many soldiers' weapons?

This question really bothered Chu Yu for a long time, but the word "Feng Zhen" suddenly popped out of his mind, but it made him have a bold guess.

"During the Fengzhen period, the Shang Dynasty was at war with the Great Zhou...... Could it be that the original owner of this treasure is a certain general between these two countries, and it seems that only in this way can it be explained......"
