At present, the level of the gathering place is not enough, and there are still too few things open in the tower.

Yang Xu walked into the door of a museum called Time and Space Museum, there were countless books inside, time was static in it, it didn't take time to read books inside, and when you came out, it was only one second away from before you went in. Of course, there is a limit to the existence of such a bug, if you practice martial arts or meditation magic in it, or do something else to improve your strength, it will consume your vitality.

However, for Yang Xu, increasing knowledge is also a means to improve his strength, Yang Xu read all the books in it, and the books in it mainly explain the structural characteristics of most creatures in the universe, preferences, living habits, some achievements of scientific and technological civilization, some cultivation knowledge of martial arts civilization, and so on.

In the next second, Yang Xu appeared in the square, it felt really amazing, Yang Xu's temperament changed in the dark, and he actually looked more like a scholar.

Yang Xu didn't know, the Time and Space Museum is only open to members of the Tianzihao, the Tianzihao and the Tianbang here are two different things, this is a secret, not the members of the Tianzihao determined by the Yuan Ling will not have this opportunity to discover this door, and there is only one chance to enter in a lifetime, if you don't finish reading all the books inside, then there will be no second chance.

Yang Xu has a deeper understanding of this strange universe, for example, ordinary people know rockets, missiles, spaceships, etc., but you don't know how to make them, you just know what they do. To put it bluntly, it is to increase knowledge.

The experience of the Time and Space Museum, Yang Xu can be said to have undergone a transformation.

It can be said that without this experience, Yang Xu would have died thousands of times, and there is a certain number in the dark, which is all fate.

Yang Xu closed his eyes to sort out the surge of knowledge, and at this moment, many people appeared in the square one after another, all of them were some people with lively minds in Yang Xu's gathering place, Yang Xu pretended not to see it, and stepped directly into the Martial Arts Scripture Pavilion.

Yang Xu learned about the advantages and disadvantages of various civilizations through the time and space museum, and finally chose to take the martial arts, scientific and technological civilization can travel in the starry sky with the help of foreign objects, and with the help of some powerful scientific and technological products, it can also have the power of fighting the heavens and the earth, the advantage is that as long as the level of scientific and technological knowledge is reached, it can be achieved quickly, but after all, it is a foreign object, and people cannot live forever when they die.

Magic civilization, and martial arts civilization has the same thing, but one is in full development, one has gone to the extreme, magic civilization majored in divine thoughts, in order to strengthen the affinity for various elements, but the flesh and blood have been neglected, and it takes a lot of time to accumulate, the main thing in life is to meditate to gather magic, learn spells, etc., the advantage is that it is more than attacking the enemy from a distance, and the explosive power is strong, the power is great, it can be said that the tree is wiped out in a snap of the fingers. The weakness is that the qi and blood are weak, the physical body is not strong enough, it is easy to be attacked by close quarters, and the cultivation is boring and boring, which is not the type that Yang Xu likes.

Martial arts civilization is different, the spirit and spirit are fully developed, although the cultivation is more arduous and dangerous, and the requirements for talent and chance are higher. The advantage is that there are almost no weaknesses in all-round development, and there is no end to the martial arts, and it can live forever, but the disadvantage is that it cannot be achieved quickly, and the cultivation path is dangerous, and the mortality rate is too high.

Yang Xu entered the Martial Arts Scripture Pavilion and found that the open bookshelves were very rare, and many of the bookshelves had enchantment protection and could not be approached, which may be a problem that the level of the Demon Suppression Tower was too low and the authority was not enough.

Yang Xu now also knows that the Demon Suppression Tower is divided into 10 levels, and what Yang Xu has now is only level 1, and the things he can contact are limited, all of which are things that do not exceed the scope of the 1st order, Yang Xu hates it with gritted teeth, and it is imminent to improve the level of the Demon Suppression Tower, this is also the means of Yuan Ling, for this Demon Suppression Tower, people like Yang Xu who don't want to be saviors will be forced to embark on the road of saving the world.

Every time it is promoted, the population of the gathering place needs to be increased by 10 times, theoretically the volume of the earth can reach level 9 at most, and it is impossible for the 10-level true body to come, Yang Xu Mo calculated that it takes 500 billion people, it is impossible to have so many people on the earth, and the 9-level real body projection is only theoretically possible, it needs 50 billion people, and in terms of the population of the heyday of the earth before the end of the world, the Demon Suppression Tower can also reach level 8, but now in the end of the world, it is difficult for the population of the earth to recover the number of the heyday, Therefore, it is still unknown whether level 8 can be reached, and I can only think about it, and even if it can be reached, it will take at least hundreds of years.

Although there are a lot of exercises that can be selected in the first order, most of them are garbage, and the asking price is not cheap, requiring 10 spirit crystals or magic crystals of equivalent value, Yang Xu smacked his tongue for a while, he couldn't afford to buy it.

However, Yang Xu finally exchanged it for a book of Sitting and Forgetting Gong at the cost of 20 attributeless magic crystals, this exercise is a basic internal skill, and there is no grade. The level of exercises and the level of skills are the same, and this sitting and forgetting gong is not even ranked in the grade, which can be regarded as rubbish.

However, Yang Xu had to change, because Yang Xu felt that there seemed to be something more in his sea of consciousness, and he had to have an exercise to look inward. Fortunately, even after learning the exercises, they can be replaced. The permission for good things is not enough.,Only change a garbage book and make do with it.。

Yang Xu spent 10 magic crystals in the Tibetan Scripture Pavilion to rent a cultivation room, opened it and sat and forgot to work, according to the posture in the book, and commanded the spiritual power in the body to run the so-called several big weeks according to the running route described in the book, Yang Xu didn't feel anything, it seems that the garbage is indeed garbage, fortunately, Yang Xu himself is a second-order strength, this scum is still able to catch it, it took Yang Xu four hours of time, and he was finally able to run it skillfully, which is a small achievement.

Yang Xu sat and forgot to work, mobilized his mind, and sank into his body.

At this time, it was already dawn outside, and Lei, Lin Hu and the others had already eaten breakfast and began to deploy according to last night's plan.

Lei looked at the corpses that disappeared all over the ground, surprised by Yang Xu's magic, but he didn't ask too much.

Yang Xu looked inside his body for the first time and felt very wonderful, the meridians, the dantian, the hundred veins of the limbs, the five internal organs and the sea of consciousness located in the center of the eyebrows, as if he had taken a CT scan of the whole body.

The inner vision swept to the sea of knowledge, Yang Xu found a small sword wrapped in black mist, startled, and then reacted and was overjoyed, is this the legendary sword intent, when did it appear, is it in the treasure land.

If the shadow of the small sword has not yet condensed into an entity, it cannot be regarded as sword intent, at most it can only be regarded as a prototype of sword intent.
