It only cost more than a dozen spirit stones, and Ning Chen was in the culvert cave, so he exchanged the "Complete Book of Immortal Materials" into his hand.

After that, Ning Chen didn't stay too much in the Little Thousand Hundred Spirit Diagram, and returned directly to his cave mansion.

Then, Ning Chen didn't have the slightest intention of resting, he sat directly in front of the jade case, and couldn't wait to open the "Complete Book of Immortal Materials" and began to search for the small piece of immortal wood he found, trying to find the mystery in it.

Sure enough, after less than half a pillar of incense, Ning Chen found the origin of the emerald small wooden block on the "Complete Book of Immortal Materials".

It was the thing of the fairy realm, called the Holy Immortal Tree, which had no roots or leaves, and survived by absorbing the water of the spiritual spring and the dust of the immortals.

Even in the Immortal Realm, the Saint Immortal Wood is extremely rare.

Of course, if you can use it to make it a magic weapon, its power is beyond imagination.

And when Ning Chen saw all this through the "Complete Book of Immortal Materials", his heartbeat increased significantly, and his breathing became rapid.

At this time, Ning Chen could already be sure that the small piece of wood he found in the cave could be regarded as a heavy treasure, but the premise was that he needed to ensure that that the small section of the holy immortal wood could survive, and then it would be like a spirit plant, and it could grow.

As long as it can grow to the size of the palm of your hand and form a small flying sword, you can reach the power of the magic weapon at the level of the knot, and more importantly, to control this magic weapon, you only need to build a foundation and cultivate it.

Thinking of this, Ning Chen's whole person became extremely excited, and his eyes lit up.

Subsequently, Ning Chen began to be desperate, studying how to keep the Saint Immortal Wood in stock and continue to grow through the "Complete Book of Immortal Materials".

Through study, Ning Chen generally understood that except for the fact that the Holy Immortal Wood needed a large amount of spiritual spring water and immortal dust, it was extremely similar to raising flowers, and there was nothing special about it.

The only difference may be that if it is in a natural environment, it will take a hundred years for the Holy Immortal Wood to grow an inch long, and even if it becomes a small flying sword, it will take at least two hundred years.

Two hundred years is an extremely long time for the monks in the foundation period.

If it were someone else, he might feel desperate about this, but Ning Chen was even more excited, because the existence of the Tianyin Jade Bottle could greatly accelerate the growth of the Saint Immortal Tree.

In addition, Ning Chen could find a way to improve the purity of the immortal dust and make it more vigorous.

As for the fairy dust, to put it bluntly, it is the product of the spirit stone powder mixed with some precious spirit strains, although it consumes spirit stones very much, but it is not difficult to collect.

After fully understanding the Holy Immortal Wood, Ning Chen did not have the slightest intention of stopping, and once again took out the Little Thousand Thousand Spirit Map, entered it, and began to collect the materials for making the Immortal Dust as quickly as possible.

Because Ning Chen knew very well that the small piece of Saint Immortal Wood he had just picked up was already dying, if he didn't hurry up, it would soon wither, and Ning Chen's loss would be great.

After staying in the small thousand hundred spirit diagram for another full hour, Ning Chen finally finished the materials for making immortal dust, there were spirit plants of different shapes, and there was a black spotted finch.

Then Ning Chen didn't stop for a moment, took out a full hundred spirit stones, ground them into powder, and then added various spirit strain powders and the flesh and blood of the black spotted finch to refine them.

It took another full hour, and when he looked in front of Ning Chen, a whole vat of silver-white immortal dust had already appeared.

After placing these immortal dust beside the spiritual pool of the cave and letting the spiritual spring water wet it, Ning Chen took out the jade cup from the storage ring with extreme care, and then placed a small section of holy immortal wood the size of his thumb in a large jade jar filled with immortal dust, and sprinkled a thin layer of immortal dust on it.

After all this was done, Ning Chen still didn't dare to take it lightly, whether this holy immortal wood could survive or not was the key to success or failure.

Not daring to be careless, Ning Chen's fingertips moved, and he quickly took out the Tianyin Jade Bottle from the storage ring, and then sat cross-legged in front of the vat, injecting spiritual energy into the Tianyin Jade Bottle.

In an instant, a mysterious and pleasant sound came out from the Tianyin Jade Bottle, forming a sound wave like a light yarn that surrounded that small section of Saint Immortal Wood.

At the same time, the original "dying" Saint Immortal Tree, a faint halo flashed from its surface, and then Ning Chen could clearly feel that the Saint Immortal Tree, which was full of spirituality, had begun to absorb the aura and nutrients from the immortal dust desperately.

Even a trace of colorful and immortal nourishment breath came out of the immortal dust and merged into the holy immortal wood.

"Alive......"

With such a discovery, Ning Chen's eyes couldn't help but light up, and he whispered to himself, and a flush of excitement flashed on his face.

Once this holy immortal wood can start to absorb nutrients, it means that it has begun to grow, and it is basically stocked.

Two more hours had passed, and Ning Chen could clearly see that the Saint Immortal Wood, which was originally dying, had obviously recovered, and even with the super help of the Tianyin Jade Bottle, it had grown a little, although it was only the size of a hair.

But it was only two hours, and for the Holy Immortal Tree, such a growth rate could be called a miracle.

At this rate, it only takes a short year to grow to the size of a palm and form a powerful flying sword.

Thinking about it, a monk in the foundation building period can use the magic weapon of the immortal realm, and Ning Chen can't hide his excitement.

Even if Ning Chen took care of it and improved the immortal dust, maybe it wouldn't take more than a year.

Subsequently, Ning Chen did not stay in front of the vat too much, but just filled the Tianyin jade bottle with aura, carefully placed it on the vat, and rested alone.

Without Ning Chen's control, the Tianyin Jade Bottle could still operate on its own for a period of time until the aura was exhausted, but its effectiveness would be somewhat weakened.

Of course, it was unlikely that Ning Chen would have been waiting in front of the Saint Immortal Wood all the time, he had other things to do.

After resting in another cave for a few hours to restore his state to the best, Ning Chen once again stepped into the Heavenly Sound Realm of the Little Thousand Thousand Spirit Diagram, sat cross-legged, and swallowed the Yunhui Pill.

And this Yunhui Pill is also the strongest pill among all the pills that Ning Chen has taken.

Almost at the moment when Ning Chen swallowed Yunhui Dan, Ning Chen only felt that his majestic dantian spirit lake instantly became tumbling, like a stormy wave, and above the dantian spirit lake, Ning Chen had a feeling of thunder and rolling.

In just a few breaths, Ning Chen's fair cheeks had begun to turn red, and the blood in his body was flowing wildly in his body, and his heartbeat was even faster. (To be continued.) )
