Today, Li Nan lives cautiously, and when he holds the pen, he has to handle it gently, for fear of accidentally breaking the pen. This is especially true when doing other activities, and I don't even dare to contact other students, and this state is estimated to take several days to ease up, because even if there is a balance technique on the side of the Tunguska Empire, it will take a few more days of practice to be able to coordinate.

I didn't have time to study at night, but I did a few hours of balancing techniques before heading to the cultivation planet again. This time, he is much more courageous, in the end, he also has the realm of foundation building perfection, and he can be regarded as a low-level monk on the cultivation planet, not the ant who was casually crushed to death by others before.

Now it's going to have to be a big ant.

There is a library hall on the cultivation planet here that specializes in selling all kinds of classics, of course, there will definitely be no secret books of some sects sold in the library hall, it only sells the exercises of some sects that have been destroyed, or the ancient exercises that have been eliminated for a period of time.

Li Nan is playing with the ideas of those ancient exercises, and the "Mixed Yuan True Scripture" he is practicing now is one of the ancient exercises.

It's not that the ancient exercises are bad, it's just that the cultivation methods in the cultivation world have been reformed many times, and the cultivation speed is much faster than the exercises in ancient times, so those slow and gentle exercises in ancient times have basically been abandoned.

In ancient times, the entire cultivation world was not as chaotic as it is now, nor was it divided into so many sects as it is now, and there were mainly only three sects.

The first place in the ranking is to follow the rules of heaven and earth, and the practice is cycled one by one according to the small Zhou Tian and the big Zhou Tian, and no one of the meridians in the body is missing, and the Tao cultivation system of a acupoint is not missed. The disadvantage of the exercises is that the speed of practice is very slow, and the advantage is that the requirements for qualifications are not high, but the requirements for the mind are extremely high.

That is to say, it doesn't matter if you belong to that kind of physical qualification, but your brain must be good, and if your brain is not good, you can grind it slowly with time.

Now it is basically eliminated, because the lifespan of living beings in ancient times is completely different from the lifespan of living beings today, and the average life expectancy of living beings in ancient times can exceed three hundred, so naturally there is no need to worry, just practice slowly.

However, now that the average life expectancy is less than 60, and the physical fitness is not as good as in ancient times, if the foundation cannot be built before 30 as soon as possible, there is basically no hope for the future.

The second system is the predecessor of today's martial cultivation, physical cultivation and demon cultivation. Almost all of them were the cultivation methods of the ancient barbarians, but they were later transmitted to the human race, and after many years of differentiation and evolution, they gradually became what they are now.

The main process of cultivation is to train the body, kill other beasts and beasts, and improve oneself through their essence and blood. In general, the cultivation speed is very fast, the requirements for qualifications are relatively low, and the attack power is also quite good, in the case of relatively low cultivation, this type of monk is much stronger than ordinary Qi cultivation monks.

The only drawback is that this type of monk is quite difficult to advance in the later stage, and there are almost no ways to extend the lifespan of their own exercises, and the lifespan limit is half shorter than that of normal Qi cultivation.

Demon cultivation is slightly better, because demon cultivation itself has also learned a little bit of qi cultivation method.

The third series is the ancestor of the current cultivation of the common exercises on this side of the planet, they were very miscellaneous at the beginning, and they were basically only casual cultivation, not very recognized by the world, and the cultivation exercises were also stolen from the east and the west.

But who would have thought that the changes of the times were so wonderful, the original Taoist cultivators gradually declined over time, and they were so strange that they kept trying Fu Array Dan and the like, and the monks who seemed to be things like the side door in ancient times actually stepped into the orthodox position.

In ancient times, the Taoist cultivation disdained anything other than their own cultivation, and in their view, the Tao of the self was the foundation of everything, and everything else was just a small path.

However, the aura of heaven and earth gradually decreased, and its own cultivation became more and more difficult, and the Taoist cultivation system was still outdated after all, and was eliminated by the times.

Therefore, later on the exercises of Taoism were not so precious. In today's era when Taoist cultivation almost non-existent, some of the Taoist exercises are basically rotten streets, as long as there is money, anyone can buy them, and everyone will rarely practice when they buy them, basically as a reference, after all, the Taoist cultivation method is the source of the world's cultivation exercises, and there is still some reference value.

The primitive exercises of Taoist cultivation are actually equivalent to Li Nan's "Tao Te Ching" over there, each of the Dao sects has its own inheritance scriptures, and some scriptures may be unique books, not passed on at all, and outsiders can't see them at all.

But the "Tao Te Ching", which is the source of the Tao Classics in the world, is a rotten street, everywhere, and things in the world are so wonderful.

The library hall is an alternative, a bookstore in the cultivation world jointly established by many sects, and all kinds of cultivation exercises in it are basically offered by them.

The reason is very bright and righteous, saying that it is to promote the harmony of the spiritual world, to promote the cultural knowledge of the spiritual world, and to promote the circulation of the practice of practice, and at the same time, it is also for the benefit of the vast number of scattered cultivators.

But in fact, everyone knows that the Dao cultivation method that has been detached from the rich aura of heaven and earth in ancient times is actually a waste book, and if you want to practice, you don't know how many resources it will cost.

But Li Nan didn't know, Li Nan even felt that he was particularly suitable for this exercise, because this cultivation speed was completely beyond his imagination. That's why I hurried over and tried to buy this exercise back. Of course, another reason is also because he really can't buy other exercises, and at the same time, he doesn't want to worship other sects, so he can only choose this.

He didn't want to think about it, just because he had consumed nearly ten spirit crystals just by cultivating to the foundation building realm, what was the concept of ten spirit crystals? There were not so many heads in some medium-sized sects, and the heads of low-grade sects might not have seen them.

Even in ancient times, it wasn't a rotten thing, it was an extremely rare thing.

Li Nan originally thought that the library hall would be the same as other shops, and he was already ready to explain why he wanted to buy those exercises.

Who knew that this library hall was still an unmanned sales store, all the exercises were stored in the white jade slab in the middle of the main hall, as long as the spirit jade was put on the side, and then selected the exercises in it, the white jade slab will automatically transmit the exercises to the buyer's mind, which can be regarded as a very intelligent operation.
