The encounter with Pangu was just an accident, although Yu Bin was not disgusted, in fact, for the three tasks in hand, he was already looking for a suitable teammate.

Theoretically speaking, Ailan and they can also accompany Yu Bin to complete this task, but in fact, this idea is very unrealistic, on the one hand, counting Ailan, the number of five people is not enough to achieve Yu Bin's purpose, and the team composed of pure undead players is not conducive to dealing with various emergencies, on the other hand, as Yu Bin's plate is getting bigger and bigger, each of them has a big mess of things to deal with, and they are no longer able to accompany Yu Bin all day and night to fight monsters and brush copies like before.

However, before thinking about how to improve the composition of the team, Yu Bin must also complete his primary purpose of coming here.

The third floor of the Martial Arts Association is where all kinds of academic materials are stored, and after Yu Bin shows the administrator here—a sign that Nomenkan left beside him before leaving—he can flip through the academic materials stored here at will.

Academic can be said to be the cornerstone of all professional skill systems in the Entagri Continent, whether it is a player or an NPC, you must master the corresponding academic premise to be able to learn the corresponding skills, otherwise, no matter how high you raise the level, you will not be able to master any professional skills (some basic general skills do not require pre-academic requirements).

But in fact, whether it is in the past life or in this life, players' understanding of academics is at a very superficial level, in their opinion, academic and other skills in online games are no different, as long as you invest in academic points, light up the corresponding academics in your academic list, even if you complete the academic mastery, all that remains is to learn skills, and then release skills through the assistance of the system.

However, that's not what academics are really about! This point, so far, may only be clearly realized by Yu Bin.

Each academic is like a mathematical formula, when the player is invested in the academic to light up the academic, it is like writing down the mathematical formula in a notebook, and the skill is equivalent to an arithmetic problem, after satisfying the mathematical formula required for the arithmetic problem, the result can be deduced according to the prescribed steps.

But if that's it, the player only has academic rights, not ownership, that is, they just know that there is such a mathematical formula, but they have no idea what the mathematical formula means, how to derive it, and under what circumstances it can be used!

Therefore, after the fusion of games and reality in the previous life, the vast majority of human beings lost their power in the game and had to struggle to survive from scratch, and their academic neglect is also a very important reason.

NPCs, on the other hand, don't have what the player calls academic points, so every single academic item they have mastered is completely mastered through their own learning and understanding, in which case their power can be almost unlost! Similarly, due to the academic skills that are mastered through their own strength, many NPCs are involved in many fields and do not focus on one aspect like the player, which is one of the reasons why NPCs often juggle multiple classes at the same time.

Therefore, really smart players will try to understand the meaning and principles of this academic while learning academics, so that they can truly master this academic, they can not only integrate it by reading academic books, but also through the teaching of mentors. Although this will cost them a lot of energy on it, it will have a very important meaning for their future.

This is also the reason why Lei Guang gave up most of his time for leveling and devoted his energy to the library like sprinting for the college entrance examination.

Of course, the academics of warriors and magic have a significant difference in difficulty for players, the former is more focused on actual combat, and the latter is more focused on theory, which is one of the reasons why Yu Bin chose Death Knight instead of being a lich, no matter how you look at it, [Weapon Mastery] and [Soulology] are obviously more acceptable to a player who grew up in the scientific world.

Yu Bin closed the book in his hand, clicked the [Heavy Sword Mastery] on it to level seven through the system panel, put the heavy book back on the shelf, and began to look for another academic book about [Plate Armor Mastery].

As for understanding, Yu Bin doesn't know how much he really has mastered these academics, there is no progress bar or hint to tell the player in this regard, it can only be subjectively judged by the player himself, unless Yu Bin doesn't use any academic points to improve the academic level from the beginning, in that case, to what extent he masters, this academic will automatically improve to what extent.

But that would be unacceptable to the player, and no one would want to spend years of studying this scholarship and then watch someone else achieve the same academic level in just a few weeks.

Of course, since the academics that are fully mastered by the player do not need to spend academic points to upgrade, in fact, the player can also guess which academics have been mastered by themselves through the extra academic points in their hands, but this method is either difficult to judge or very troublesome to implement, so few people do this frequently.

It took several hours to light up all the required academics, Yu Bin left the Martial Arts Association, which is different from the theoretical academics of [Soul Science] or [Tectonics], although there is also a certain theoretical knowledge of [Weapon Mastery] and [Plate Armor Mastery], but it is more of a practical experience, when a warrior wields a weapon to fight, he is actually understanding the academic knowledge about weapons, but few people are aware of this.

The profession of [Death Knight] that Yu Bin wants to work for is very demanding in terms of academics, even through the Martial Arts Association, Yu Bin can only barely meet the requirements of those ordinary academics, and as for the more advanced and rare academics, Yu Bin is powerless for the time being.

For example, the five basic academics of the undead clan [weapon mastery], this academic is the foundation of all weapons academics, and various branch academics and advanced academics produced on the basis of this academics, whether it is in the martial arts association or in the witchcraft association, there are very detailed materials.

The only difference is that the Martial Arts Association focuses more on academics related to warrior weapons, such as [One-handed Sword Mastery], [Two-handed Sword Mastery], etc., while the Witchcraft Association focuses on mage-related academics related to weapons, such as [One-handed Staff Mastery], [Two-handed Staff Mastery], etc.

But you can't expect these associations to have legendary scholarship like [Immortal Will] or [Baptism of Death], and even the almost [Death Declaration] and [Soul Rhythm] cannot be found in these associations.

It's like you can find books on fundamental physics theory in the library of any university, maybe more advanced books on applied physics, and depending on the situation, you might even find books on how to make an atomic bomb. But you can't find sand in a random university library. The detailed manufacturing process of Lin poison gas, which is almost only in the hands of a small group of people or institutions.

After dealing with some of the academic problems, Yu Bin left the Martial Arts Association, and unsurprisingly, at the gate of the castle, he ran into the Wall of Sighs waiting there.

Seeing Yu Bin come out, this undead shield warrior happily greeted him: "I thought you left first!" I've already told my teacher that you can go at any time! ”

Yu Bin felt that the other party was probably just free-range by his teacher.

"I'll have to get some help, not just the two of us!" Yu Bin nodded towards the bone, "You can go back and prepare supplies first, and I will inform you as soon as I have enough manpower in the next few days." Also, what grade is that shield in your hand? ”

"Blue Refinement Gear!" Pan Gu raised the shield in his hand, "I spent a lot of gold coins to get it back from the auction house. ”

"I'll get you a rare shield! With this thing in your hands alone, I don't dare entrust my life to you! ”

Yu Bin was going to consume some of the high-level equipment accumulated in the warehouse, and he had scavenged a batch of good equipment in Mosso Black City, a large part of which had been turned into gold coins and supplies, and the rest of the fine products were kept by Yu Bin as a reserve just in case.

"Ahh Good, good! No problem! I'm always available! Hearing that Yu Bin was a red rare-grade shield as soon as he made a move, Pan Gu was shocked by the other party's background, but also glad that he was lucky, not everyone has this luck to be favored by the famous Ice Whisper Dry Bone.

After bidding farewell to the bones, Yu Bin returned to Naxxramas to practice his newfound skills while considering which mission to choose.

The Room Fortress was first abandoned by Yu Bin, although the idiot golden dragon is not a big problem, but the big devil hidden behind it is not something that Yu Bin can deal with now, the devil who is good at directly touching the soul is the most hated enemy of the undead, compared to other races, the undead who rely on the soul fire as a source of power are more vulnerable in front of these cunning and insidious creatures.

The second to be excluded is the Wailing Cave. The turmoil in Mogaure has not long passed, and now the entire barren land is in a kind of prelude to chaos, the orcs and trolls want to bite hard from the weakened minotaurs, and the elves want to recruit the minotaurs while repairing the backwater oasis, and the elven druids mentioned in the mission are likely to be for this purpose, in this case, Yu Bin does not think that he can get much benefit from those long ears, especially since it is likely to involve the Emerald Dream and the Green Dragon.

As a result, the only thing left is Blackstone Mountain.

Although in terms of danger, Blackstone Mountain is even more dangerous than Room Fortress, regardless of the Black Dragon Prince Nefarian and the Fire Elemental Lord Ragnaros, just the little brother under the hands of these two gang bosses is enough to give Yu Bin a headache, whether it is the fire element or the black dragon, any one of them is a high-level monster of the elite template, and it also comes with various additional bonuses, what fire element immunity, flying creatures, large size crushing, etc., just thinking about it makes Yu Bin's scalp tingle.

What's more, there are a large number of black iron dwarves enslaved by these two forces, although these black dwarves have died by themselves, from good citizens to hard slaves, but this does not mean that they are too vegetable, but the enemy is too strong. In fact, due to the monopoly of Blackstone Mountain for thousands of years, the military strength of the Black Iron Dwarves is even higher than that of the Dwarven tribes of Ironforge Castle, and from the player's point of view, these Black Iron Dwarves are of higher level and better equipped as monsters.

Of course, in addition to these obvious difficulties, it is not without good news.

First of all, because of the hostility between the two bosses, whether it is the Fire Element Legion or the Black Dragon Legion, they will definitely put the main strength on each other, and it is impossible to send too much power to find trouble with Yu Bin, the only thing that needs to be considered is those Black Iron Dwarves who are slaves.

Secondly, compared to the dispensability of Iron Forger to Blackstone Mountain, the orcs obviously paid more attention to the abnormal movements in the Burning Plains, and if nothing else, Yu Bin could get some extra help from the orcs. Of course, the main energy of these green-skinned beasts at the moment is probably still on the Barren Land and Mogaolei, and they will hardly spend too much capital to fight for Yu Bin.

As for the last good news, only Yu Bin knows, that is the black dragon princess Onexia!

In the previous life, many people thought that Nefarian, the black dragon prince, Onexia, the black dragon princess, and Sinestra, the black dragon queen, were a family, but in fact, this was just a matter of assumption.

In fact, these three are not related by any blood. Just as Demogorgen is called the Demon Prince, Nefarian is not called the Black Dragon Prince because he has the blood of the Black Dragon King Nesario, but relies on his own strength to obtain the title of the Black Dragon Prince, and in the same way, the Black Dragon Princess Onexia is not the daughter of Sinestra, nor is she Nefarian's sister.

As far as Yu Bin knew, unlike Nefarian, who had always shown that he wanted to replace Sinestria and become the ruler of the Black Dragon Clan, the Black Dragon Princess Onexia hid her ambitions even deeper. This sinister she-dragon has spent hundreds of years building a vast network of relationships across the Arnas Empire. Now she is in the form of a human woman, Katrana Presto, who controls most of the empire's foreign trade as an earl.

In Yu Bin's memory, the prince of the Arnas Empire in his previous life, Rasfil, suddenly fell, defected to the Black Dragon Legion, and assassinated his father King Irenas in public. After the fall of King Arenas and the rebellion of Prince Rasfil, Onexia, who became a countess, assisted the young prince Ureon with the Duke of Boval Vortagen, and gradually took the power of the Arnas Empire into his own hands.

If it weren't for the camp war and the bottomless abyss invasion that broke out later, the countess didn't have time to realize her scheme, I'm afraid that the entire Arnas Empire would have turned into a paradise for black dragons and dragons.
