Leaving everyone's sight, he walked to another area on the platform, and finally no one was paying attention to Lin Yuan's every move.

He spent five hundred yuan to take a bath in a bathhouse on the platform, then changed the clothes he had just bought, replaced the tracksuit on his body that had become dirty and somewhat torn from the long battle, and immediately found a place to sit outside the bathhouse.

While eating the food, Lin Yuan used his consciousness to connect to the light cluster above the platform.

On the platform of the Secret Realm of the Ash Forest, there are eight clusters of light, five of which are secret realms, one is a list that records the clearance time of the secret realm, and two are mysterious shops and halls of knowledge.

The Mystery Shop will produce some items that are unique to the opening of the Astral Boundary, the refresh time is random, each time a thousand items are refreshed, the purchase price is different, each refresh only lasts five minutes, and each person can only buy one.

The hand is fast, the hand is slow.

In the previous life, after the mystery shop was opened, some people never took the initiative to go to the secret realm to level up and become stronger, but specialized in squatting in the mystery store, getting some high-value items to resell in exchange for profits, and then buying equipment to become stronger, and finding a master to upgrade.

Although the speed of becoming stronger in this way is very slow, at least it is not life-threatening, so there are many people engaged in this industry.

Everyone has their own way of living, because of factors such as personality and growth environment, not everyone has the potential to become a strong person, so although Lin Yuan does not agree with engaging in this industry, he has no prejudice against it.

If the role of the mystery shop is to give birth to a new industry, then the temple of knowledge can be said to be the existence of subverting the entire earth civilization.

In the Hall of Knowledge, all the knowledge in the entire astral realm is recorded, as long as the conditions are met, these knowledge catalogs can be retrieved, and as long as you can pay a sufficient price, then you can learn the retrieved knowledge.

The intelligence value of a normal earthling person is about 10 points, and the intelligence value of some great scientists who are rich and rich will not exceed 20 points, and Lin Yuan's intelligence value can reach 233 points, and most of the knowledge is obtained through the palace of knowledge in the long years.

Before clearing the Graveyard of the Brave, it was indicated that the Mystery Shop and the Hall of Knowledge had been opened, and Lin Yuan could also receive additional rewards here.

In the mystery shop, the extra reward given to Lin Yuan is that he has a chance to take the initiative to refresh the mystery shop, and the refreshed list of goods is still a thousand, which still lasts for five minutes, but only Lin Yuan can buy it.

"Counting the star coin cards issued in the treasure chest before, my star coins add up to more than 20,000 points, and the things that are swiped out in the mystery shop require up to 100,000 star coins for a single piece, and if I swipe out something that I can't afford, it will be embarrassing. ”

Lin Yuan thought so, and after confirming the reward of the Mystery Shop, he broke the consciousness link with the Mystery Shop's light group, and instead turned his attention to the Hall of Knowledge.

There is the knowledge of the entire astral realm in the temple of knowledge, but not only does it take a price to learn, but even there is a price to pay for retrieving the knowledge catalog, and everyone can pay a price of 10,000 star coins per day to search the knowledge catalog.

The Hall of Knowledge will randomly refresh ten kinds of knowledge that can be learned, and it will not disappear if you don't continue to refresh, as long as you meet the conditions and pay the price, you can learn it.

The additional reward that Lin Yuan received in the Hall of Knowledge was like being able to refresh the Mystery Shop for free, and it was an opportunity to search the knowledge catalog for free and learn.

The knowledge catalog has always existed since the search, and it will not disappear if it is not refreshed again, so Lin Yuan has no scruples this time, and after confirming that he has such a chance, he will use it directly.

"The knowledge catalog has been searched. ”

This information appeared in Lin Yuan's consciousness, and then ten knowledge catalogs that could be learned appeared in front of Lin Yuan's eyes, because his intelligence value was relatively high, so the ten knowledge catalogs that were refreshed were all relatively advanced.

"Level 19 Magic Mosaic Notes", "Level 21 Alchemy Summary", "Great Cracking Technique", "Red Lotus of the World", "Gonzo of the Great World", "Guide to Making Antimatter Bombs", "Summary of Black Hole Research", "The Great Five Elements Yin and Yang Extinction Sutra", "Goddess of Light Photo Book", "Great Shifting Technique"

After reading these ten knowledge catalogs, the corners of Lin Yuan's mouth twitched, and he didn't know whether he should praise his good luck or memorize it.

Among these ten knowledge catalogs, "The Great Splitting Technique" and "The Great Shifting Technique" are forbidden spells, ranking 21st and 18th respectively among the 21 sequences of spell levels, and are the dream skills of all mages.

Among them, the Great Splitting Technique can disintegrate everything, which can be performed by a level 21 mage, and can even disintegrate a plane, which is called a forbidden spell at the counterplane level, while the Great Shifting Technique can cross a long distance at a time.

But it's a pity that this is useless for Lin Yuan, first of all, the things learned in the Hall of Knowledge are different from the skill books, even if he knows these two forbidden spells, Lin Yuan doesn't have so much mana to release.

It's not like a skill book, but it can not only be learned, but also made people achieve all the prerequisites for releasing this skill.

In addition to these two forbidden spells, such as "Guide to Making Antimatter Bombs" and "Summary of Black Hole Research", which are obviously advanced research projects of scientific and technological civilization, and obvious entertainment content such as "Goddess of Light Photo Book" and "Gonzo of the World", are of little use to Lin Yuan.

Therefore, Lin Yuan's scope of free knowledge acquisition this time is very narrow.

"Level 19 Magic Mosaic Notes" and "Level 21 Alchemy Summary" are very useful, one can add magic patterns to equipment and enhance attributes, and the other can create super powerful various magic equipment and even artifacts.

But for Lin Yuan, it is still a chicken rib, because the Palace of Knowledge never gives you to play with nothing, it is said that there are as many levels as there are, and the 19-level magic pattern inlay is level 19, and there will definitely be no level 1-18 magic pattern inlay.

Without the previous technical foreshadowing, you basically won't need it once you learn it, and the same goes for the level 21 alchemy summary.

The Red Lotus of Annihilation is a powerful martial art that is driven by super strong qigong, and its power is comparable to that of a level 21 forbidden spell cracking technique, but it is still the same sentence, even if Lin Yuan learns it, he will not be so powerful qigong to use.

In this way, Lin Yuan only had one target left to choose from.

"This is the so-called Great Five Elements Yin and Yang Extinction Sutra? Lin Yuan opened his eyes, and the piece of jerky that he was chewing in his mouth almost squirted out.

In the introduction of the Temple of Knowledge, the Great Five Elements Yin and Yang Extinction Sutra is a profound method of qigong cultivation, and after cultivating to the end of the world, people can have a super strong qigong that exterminates the five elements of yin and yang.

This kind of introduction, this kind of extremely immortal name, made Lin Yuan look forward to it very much, this is a super mastery that he couldn't learn in his previous life, can he use this to cultivate into an immortal?

Then, when he really learned this qigong from the Hall of Knowledge, Lin Yuan's face became an extremely distinct emoji.

Are you TM kidding me?
