At the door of the hall of classics, there was only an old foundation building period cultivator watching.

To enter the Hall of Classics, you only need to show the identity token of the Dao Alliance.

Wei Li walked into the hall of classics and found that there were not many books in the hall of classics, which was only equivalent to a small library.

There are several rows of bookshelves inside, and the shelves are divided into various books.

These books are all retypeset and printed using modern printing techniques.

There are books on exercises, alchemy, refining tools, drawing talismans, etc.

However, due to the fact that the immortal cultivation inheritance of the Huaxia Immortal Cultivation Realm was lost a lot hundreds of years ago, the exercises in this classic hall were very ordinary, and there were many missing.

Compared to the Xuantian Liuhe Gong that Wei Li is cultivating now, it is much worse.

At least the exercises of Xuantian Liuhe Gong are complete, and the exercises are peaceful and peaceful, and the mana after cultivation is a little stronger than ordinary exercises.

This is already very valuable on the earth, where exercises are extremely scarce.

Although Wei Li did not practice the exercises of large sects such as the Kunlun School and the Shushan School.

However, Wei Li felt that the exercises he practiced should be no worse than the Kunlun Sect's inheritance exercises.

At least the last time they met Ling Xingyu, a disciple of the Kunlun Sect, the two of them wrestled with each other simply with the coercion of the exercises, and in the end, they were evenly matched.

If Wei Li's cultivation level was worse than that of the Kunlun School, I am afraid that Wei Li would fall into disadvantage at that time.

Wei Li's bookshelf checked it a little, then skipped it directly, came to the bookshelf of other categories, and investigated.

"Alchemy, it's not as good as the inheritance I got!

Alchemy is not very clever.

Talisman making, forget it!

These talismans are too low-level, and with my cultivation in the Void Pill Period, I can't use them anymore!"

Finally, Wei Li came to the corner of the bookshelf, and in that corner there were some very unpopular books.

And some of the books turned out to be very old.

Apparently these books have not been bought for a long time.

Even the Hall of Classics did not bother to use modern printing technology to reformat and print them.

Wei Li picked up one of the old-looking books, opened it and looked at it, and immediately his eyes lit up: "The refining method of the spiritual root!"

Wei Li suddenly became interested.

He didn't have a spiritual root himself, but it was because he got a top-grade spiritual root that he embarked on the road of cultivating immortals.

Wei Li already had a general understanding of the refining method of the spiritual root.

However, Wei Li was not clear about the detailed refining method.

Wei Li was very interested in the refining method of this spiritual root.

That's because his grandfather, mother, and girlfriend are now just mortals.

They don't have spiritual roots on their bodies, so they can't cultivate.

If you can find some heaven and earth spirit roots, use the refining method of this spirit root, refine them into acquired spirit roots, and refine them for grandparents, Yu Ziyao and others.

In the future, they can also be like themselves, they can practice the Immortal Cultivation Method, and they will be able to live longer in the future.

Wei Li didn't have to worry about a hundred years later, watching these relatives die one by one because of the exhaustion of their longevity.

Immortal cultivators are lonely.

If fellow relatives don't have spiritual roots, they can't cultivate like immortal cultivators.

At most, they will all grow old and die.

At that time, as an immortal cultivator, he was undoubtedly very sad and helpless.

After all, the lifespan of a mortal cannot be changed even by an immortal cultivator.

Unless those mortals are able to cultivate on their own and gradually change their own lifespan.

If Wei Li could refine it into a spiritual root, then the situation would be different.

As long as fellow relatives have refined the spiritual root, they will be able to cultivate just like themselves.

The lifespan will also become longer and longer as they progress.

At that time, I was really able to stay with them for a long time.

Wei Li carefully examined this ancient book and found that the spiritual root refining method recorded in the ancient book was very detailed.

As long as Wei Li finds the spiritual root of heaven and earth, and strictly follows the refining method written in the ancient books, he will definitely be able to refine the spiritual root.

Wei Li's heart rejoiced, and he immediately decided to exchange his contribution points for this book.

This book is useless on the earth, after all, the spiritual roots of heaven and earth on the earth have basically dried up.

Even if there is a method of refining, there is no way to find the spiritual root of heaven and earth to refine.

But Wei Li is different, he can shuttle to the other world!

There is no heaven and earth spiritual root on the earth, but it does not prove that there is no other world!

If Wei Li was allowed to find the spiritual root of heaven and earth, Wei Li would have the confidence to lead his relatives on the path of cultivating immortals together!

Wei Li skimmed through the rest of the books a little more, and found that they were all books that didn't help him much.

So Wei Li took the book that recorded the method of refining the spiritual root of the soul and walked out of the hall of classics.

Wei Li put the ancient book in front of the old man in the palace, and the old man glanced at the ancient book in front of him, and said expressionlessly: "A total of five thousand contribution points!"

Wei Li was stunned for a moment, thinking that this classic book hall was too dark, right?

It's just a miscellaneous book, and it goes to nearly half of my contribution points.

However, Wei Li was finally relieved in his heart, in today's earth where immortal cultivation classics and cultivation resources are extremely scarce, every classic book on immortal cultivation skills is very valuable.

Being able to exchange 5,000 contribution points for such an ancient book for refining spiritual roots is already good.

Wei Li didn't speak, just took out the token and asked the old man to deduct five thousand contribution points from the token, and then took the classic book and left the Dao Alliance.

After Wei Li left the Dao League, he flew all the way to the mountains, and found a very secret cave in the Taishan Mountains as his temporary cave house.

The cave is narrow on the outside and wide on the inside, and after Wei Li entered the cave, he took a big stone from not far away to block the cave.

After Wei Li entered the cave, he immediately waved his hand, and a translucent jellyfish with a diameter of ten meters appeared on the ground of the cave.

This jellyfish is the invisible jellyfish demon that Wei Li killed in the deep sea.

At this time, the jellyfish demon was too dead to die, but its skin was still smooth and white, and it looked very tough.

This jellyfish demon can be invisible, and if you use its skin to refine the magic robe, it should also have a considerable stealth effect.

If you want to do it, Wei Li immediately summoned the flying sword, first released the paralyzing toxin in the jellyfish demon's body, and collected it in a container.

Then he used his flying sword to cut a large piece of skin on the corpse of the jellyfish demon.

Wei Li put away the remaining jellyfish demon corpse again, and then took this piece of skin and began to refine it.

Ten days later, Wei Li was holding a transparent garment in his hand, and his face was full of joy.

If you don't look carefully, people will think that Wei Li's hands are empty and he hasn't taken anything.

But Wei Li's heart knew very well that he had finally succeeded in refining a top-grade magic weapon-level stealth magic robe!

This cloak is extremely light and thin, as if it were nothing in your hand, and the entire robe is transparent, which is very magical.
