A large hall like a crystal palace appeared in front of him, and the building materials used in the main hall were all low-grade spirit stones, emitting a soft light, dispelling the darkness at the bottom of the river.

The main hall is surrounded by an elixir garden, but because no one has taken care of it for a long time, many cherished medicinal herbs have withered, and what remains are some elixirs with relatively strong vitality, as far as Li Shengtian's eyes can see, there are probably hundreds of them.

These are all spiritual grasses that are difficult to find outside, although Li Shengtian has not studied alchemy, he still decided to finish picking these useful spiritual grasses, maybe he will be able to use them in the future.

There is no river water in the formation, it is a small world of its own, Li Shengtian bent down and walked among the herb gardens, quickly harvesting one herb after another, these herbs are not very high grades, the best is only to reach the standard of fifth-level spiritual grass, as for some sixth-level and seventh-level spiritual grasses, they have already died, and only some seeds are left on the ground, which are picked up by Li Shengtian one by one and ready to be planted later.

Soon, Li Shengtian finished picking this medicine garden with an area of nearly 1,000 square meters, and harvested a total of more than 700 spirit grasses, from the first level to the fifth level of spirit grass, these spirit grasses are a good material for practicing alchemy, but unfortunately Li Shengtian does not have a Dan furnace, and he can't start learning alchemy.

Before coming to the main hall again, looking at this almost transparent palace, Li Shengtian sighed that the owner of this cave mansion had strong financial resources, and how luxurious it must be to build a residence with spirit stones?

The door plaque of the main hall is engraved with three big characters "Longheju", the handwriting is vigorous and powerful, quite imposing. At this moment, the door of the main hall was closed, Li Shengtian stepped forward and nudged it, and the door squeaked and slowly opened.

A straight figure sat on the futon in the middle of the main hall, but the whole body breath was not visible, and it was obvious that he had been dead for a long time, and only the clothes and hats on the skeleton remained, which made people think that he was a big living person at first glance.

Li Shengtian walked to the corpse, where there was also a four-legged Dan furnace on the ground, which made Li Shengtian overjoyed, but he did not take the Dan furnace away immediately, but respectfully made a big salute to the corpse, and said to himself: "The predecessor is powerful, the kid has no intention of offending, please forgive me, this must be the cave of the seniors, after the juniors take the things inside, they will definitely bury the corpses for the seniors, so as not to expose the dry bones, the legacy of the seniors, and never forget." ”

After thanking the dry bones, Li Shengtian carefully gathered the bones, buried them in the medicine garden outside the main hall, and erected another tombstone, only then did he breathe a sigh of relief.

The reason why he has such respect for other people's remains is that on the one hand, Li Shengtian feels that he has accepted the corpse before his death, and what should he do, on the other hand, he always feels that such a senior is powerful, and he must have some means to punish those who defile his corpse after death, Li Shengtian can't ignore the corpses of others, so he will have some pedantic actions.

It's always a good idea to be careful in the cultivation realm.

In the main hall, Li Shengtian carefully watched this simple Dan furnace, the surface of the Dan furnace is carved with cloud dragon patterns, the whole body is pitch black like ink, about half a person tall, just four legs and feet are half a meter long, standing on the ground looks extremely stable, this Dan furnace can't see what grade, Li Shengtian estimates that it must be at least the level of a high-grade spiritual weapon.

Li Shengtian, who was in a good mood, began to explore the entire hall, in addition to the main hall, there is a side hall on each side of this hall, Li Shengtian first stepped into the side hall on the left, this is obviously a place to rest, there is a wooden bed in the innermost part of the room, and there is a futon on the wooden bed, I don't know what the futon is woven into, and it has not been damaged for such a long time. In the middle of the room was a stone table, a stone bench, and a teacup on the table, apparently left by the owner during his lifetime. In addition, Li Shengtian did not find anything valuable, and he couldn't help but feel a little depressed.

However, when he stepped into the side hall on the right, his mood couldn't help but perench.

The side hall on the right side is like a study, there is a bookshelf in it, there are about a hundred books on the shelf, there is a desk not far away, a wooden chair, and a few books are also placed on the desk.

Li Shengtian walked to the desk, looked at a book called "The Autobiography of the Ancestor of Longhe" on the table, and couldn't help but pick up his hand and flip through it.

Li Shengtian's divine sense is strong, and it only takes about ten minutes to finish browsing this book, and he still remembers the content of the book.

It turns out that the owner of this hall is called Longhe Ancestor, who was a Dan Dao master a thousand years ago, and at the same time, his own cultivation has also reached the peak of the cultivation realm, but he can't sense the thunder tribulation and ascend to the upper realm, and finally his life will be exhausted before a thousand years, and he will sit down with regret, and the book also mentions the scene of his battle with a heavenly demon at the end of his life.

Li Shengtian has a general understanding of the thousand-year tribulation mentioned in the book, the cultivation realm does not know when it began, a demonic disaster will break out every thousand years, resulting in the slaughter of hundreds of millions of living beings, the human race and other races are like this, whenever the demonic disaster comes, the major forces of the human race are the same hatred of the enemy, give up some personal grievances, and fight the enemy together.

In any case, the sacrifices made by human beings to resist demonic disasters are simply unbearable to experience and understand, and each time it takes hundreds of years of recuperation to gradually recover.

Qingyang Continent, with Leizhou as the richest, where the Xiuzhen civilization is more powerful, every time a demon disaster occurs, Leizhou is the most solid backing to resist the demon disaster. The powerful monks of Leizhou will even travel to all continents to support and save the cultivation civilization of the human race on all continents from being cut off.

After reading this autobiography, Li Shengtian's heart was a little depressed, he originally thought that the Qingyun Continent could allow people to practice, he was always happy, but now it seems that the world here is not a place of happiness, especially after knowing that there are still two hundred years left in the next thousand years, the sense of urgency in his heart has become stronger and stronger.

He needs to improve his cultivation as much as possible when the calamity comes, otherwise he will face the disaster when the time comes, and he will be ants and cannon fodder.

Li Shengtian's heart was full of admiration for the Dragon River Ancestor, who did not turn a blind eye to the demon disaster because he was about to die, but dragged his dying body, fought with the monsters, and finally sat down here.

After putting down this biography, another "Compendium of Spirit Grass" and "Alchemy Guide" instantly made Li Shengtian like a treasure, and these two books were undoubtedly a relief to him.

Li Shengtian did not immediately flip through it, but chose to continue browsing the other books on the shelves, and spent the whole afternoon reading.

The content contained in these books is too rich, and the hobbies of the Dragon River Ancestor are very extensive, from the customs of various parts of the Qingyang Continent to the pattern and future development of the cultivation realm, almost all of them are involved, Li Shengtian has read these books, and he already has a more detailed understanding of the Qiangyang Continent, which is obviously extremely helpful for him to walk the cultivation realm in the future.

Li Shengtian put all the books in the storage bag, he was ready to leave here, in the main hall of the Dragon River Ancestor, not a single spirit stone was found, and the only harvest from this trip was these books and spirit grass, but he didn't have many regrets, just those two books on alchemy, he benefited a lot, where to hope for anything else.

There was a sound of water, and a figure appeared on the surface of the river, it was Li Shengtian who had returned from the bottom of the river. With a dashing turn in the air, Li Shengtian landed steadily on the bank of the river, his whole body's spiritual power was running slightly, and in an instant, water vapor was rising from his clothes and hair, and after a while, he was dry.

"This cultivation is really happiness. Li Shengtian muttered to himself, and the steps under his feet did not stop, like a cloud of green smoke rushing towards the mountains in the distance.
