Chu Xuan walked straight towards the center of the public square, where there was a patch of green gathered in the center of the place, and it seemed that the reincarnators who wanted to trade something liked to gather in the popular places.

Judging from the empty situation of the entire square, the total number of reincarnators is probably not much, if you calculate the area of one square meter per capita, it is estimated that even one thousandth of the square with a size of 1 million square meters is not enough to fill in this guidebook.

(The total number of reincarnators should not exceed a few hundred, and I'm afraid that few of them have been strengthened enough to crush the mission world, and there are not many people who have completed the mission many times, so it seems that I didn't come in very late.) ）

Chu Xuan walked around the stall in the center, and after learning about the current "economic" situation in the main god world, he had a preliminary impression of the development of the reincarnations.

There are traces of civilization wherever there are civilized people, and even some seemingly inconsequential information, such as the "price index" and the type of "trading goods", is enough to reflect some problems.

Chu Xuan mainly observed the "Task Completion Certificate" and the "Medal" given at the time of settlement, two transferable items that were not sold in the exchange shop, but were very useful.

The "Follower Contract" is non-transferable and cannot be dropped, and it is also not sold in the store, so it is a rare item at first glance.

In fact, having goods with the same function as the "Follower Contract" in the exchange shop almost all require an S-rank medal and more than 50,000 survival points to exchange, and even Chu Xuan can only afford one.

According to Chu Xuan's observation, the price of the "Task Completion Certificate" seems to be quite strong at the moment, but its value is not particularly valuable; The value and price of high-ranking "medals" are quite high, and the price of low-level "medals" is significantly lower than their value.

This shows that completing the strategy quest is not too difficult for the reincarnation, but it is quite difficult to complete the quest with a high rating, and most of the reincarnators get not enough survival points.

To be honest, Chu Xuan hadn't figured out what enhancements or abilities he could redeem for the best yet.

After all, he glanced at the exchange shop, which should be full of exercises and items from ACGMN, which was too unfamiliar to him who had only started collecting this knowledge in the 1999 Suzumiya Haru World.

Although the search function of the exchange store is very detailed, and before the exchange, it will also give an estimate of the "degree of completion" according to the individual's own characteristics, but there are nearly 1,000 items that can reach "100% completion" after Chu Xuan's exchange, and more than 10,000 items with a "completion degree of 80%" or more.

Therefore, after taking a turn in the public square, Chu Xuan did not buy weapons, armor or exercise abilities, but exchanged the transferable "Mission Completion Certificate" in his hand for a "Learning Device" and 2000 survival points for Sister Misaka in the "Magic [***] Catalog".

Looking at the other party's painful appearance, he knew that he shouldn't have much survivability until now.

But this person is not a big loss, after all, his intelligence is not high, and he has few survival points and medals in his hand, and after using the "learning device" to stuff all the necessary knowledge into his head, there is no need to keep this prop anymore.

Only an intelligent person like Chu Xuan, who has a survival point and a medal, and is still a technology maniac, will always keep this learning device.

After buying the learning device, Chu Xuan returned to his usual world and began the efficient process of "home-staying".

He used the store's personal search to sort and pick a rough one, and finally spent nearly 50 survival points to exchange all the images or text materials of the more popular and better-rated ACGMN in the store, which was so large that it took more than 40 hours to instill it into his head even at the speed of a learning device.

Then he bought all the professional materials in the exchange shop, including the natural sciences and the humanities, and it took him nearly 11,600 survival points in total, and it took more than 150 hours to indoctrinate him with the learning device.

This is still the scientific knowledge that the earth civilization will only have until 2050, and it is the real earth civilization technology, which can neither create any Gundam, nor do you have any λ-driver, and there is no technology to cultivate a large number of superpowers through scientific methods.

In the exchange shop, there are also a lot of super technological materials that even Chu Xuan is very coveted - such as the technology to create a blue tanuki-type robot from the future, and the price can only be said to be cheap compared to the final product.

However, he didn't redeem these super technologies.

Because Chu Xuan clearly knew that without an industrial foundation of the corresponding level of science and technology, most of the advanced technology products could only stay in the laboratory, or even at the drawing stage.

And although this "learning device" is really an artifact of learning and education, it is a pity that it still belongs to the category of cramming education, which can only store knowledge completely in people's memory, but cannot make people instantly integrate this knowledge.

Except for a science madman like Chu Xuan, no one would be idle enough to memorize so much knowledge.

Even if this knowledge is memorized, it must be truly absorbed and mastered through systematic training methods, otherwise it will not know what to use and how to use it after learning, and can only play the role of "mobile library".

What's more, the book of strategies has already stated that there is only one task in this world, and that is to raid beautiful girls.

However, despite knowing this clearly, Chu Xuan still spent nearly 20,000 survival points to buy a super laptop that he didn't know where it came from, and it also came with a universal file format converter and a universal interface produced by the main god, ensuring that the reincarnation person could connect to a device with similar functions in any world and function normally.

Even after this huge consumption, Chu Xuan still had nearly 40,000 survival points left, and at this time, he had completely absorbed the ACGMN information in his mind, and finally began to ponder the issue of exchanging physical fitness and exercise ability.

The six basic categories of castes in the book of guides are:

(1) The body belongs to the surname

Strength: Musculoskeletal strength, i.e. physical strength.

Constitution: Cellular viability, i.e., anti-toxicity, immunity and recovery.

Reflexes: Neural reaction speed, i.e. agility and other abilities.

Intelligence: The ability to remember, learn, understand, and imagine, i.e., the most important factor affecting the cost of skill reinforcement.

Mana: A general term for all the special energies in the body.

(2) Bloodline skills

Bloodline: Genetic changes, some of which come with skills - i.e., instincts, that can be used without intelligence.

Abilities: Most abilities are instincts hidden by bloodline, not affected by intelligence caste, but by physical fitness or bloodline purity, and need to be exchanged separately for strengthening.

Skills: Changes in the level of knowledge, excluding instincts, are greatly influenced by intelligence.

So, how should Chu Xuan choose?
