Thinking back to these memories that only he knew, Yu Bin walked in front of a huge building.

The five-storey obsidian building is arguably the most conspicuous building in the whole of Naxxramas, and the two-storey government hall is a small villa in comparison.

The exterior of the building looks like a small castle, with a noticeable retraction between each floor, and from a distance, it looks like blocks of different sizes are stacked together.

There is not a single window on the black wall, and the obsidian with a thickness of up to two meters firmly surrounds the secrets inside, and if you look closely, you can also find that each piece of obsidian is filled with some bright silver materials, if you hadn't personally seen the building needs, Yu Bin would not have believed that this huge building would need Mithril as a filler.

The obsidian obtained by the overall cutting, the high-purity Mithril, and the layer of Ovha steel used for the lining of the inner wall of the building, the difficulty of the construction of this secret sanctuary is simply frenzied, if it were not for Yu Bin from Moussor Black City, he would not have been able to build this building by himself for another five years.

Of course, the expensive materials and the extreme difficulty of building are nothing compared to the benefits that this building can bring.

As the highest achievement of the undead in magic, the role of the secret sanctuary is to control the magic power of the entire area and manage it in a unified manner, unlike the elves who use the magic power by setting up magic network nodes, the secret sanctuary of the undead is more like a logistics warehouse with great power, in normal times, the secret sanctuary interferes with the magic elements in the area through powerful power, and distributes, strengthens, extracts and uses these disordered magic elements according to the needs of the undead, and in an emergency, the secret sanctuary can be directly extracted by force, Gather all the magical elements in the area into a pool of magical energy in the Arcane Sanctuary for the necromancer to use at will, while preventing enemies from gaining any magical power.

A complete mystical sanctuary is nine floors high, covering an area of at least tens of thousands of square meters, which can not only control the magic elements, but also integrate alchemy, enchantment, secret method teaching and witchcraft research and other functions, each complete secret sanctuary is stationed at least a legendary-level existence all year round.

Of course, such a powerful function is not something that Yu Bin, a simplified version of the Secret Law Sanctuary, can do, in fact, the buildings that can fully exert the full power of the Arcane Sanctuary, there are only five in the entire Undead Clan, one in each of the three imperial capitals, and the remaining two are located in the Bone Wall, the core fortress of the Undead Clan, facing the elves, and the headquarters of the Necromancer Guild.

And it is impossible for Yu Bin to obtain the complete drawings of the Secret Law Sanctuary, and the architectural drawings of the Secret Law Sanctuary obtained from Mosso Black City are only a small part, but this small part is enough for Yu Bin to benefit a lot.

In the respectful salute of the twelve royal guards outside the gate of the Secret Law Sanctuary, Yu Bin opened the heavy obsidian door. These sixth-order and nine-rank top-level melee troops have always played an important role as a guardian in the army of the undead, and Yu Bin can have these twelve royal guards, not that he has been able to recruit sixth-order troops, but that comes with the system after the construction of the secret law sanctuary, these king guards will not obey Yu Bin's orders to leave the territory to fight, they are only responsible for defending the secret law sanctuary.

Anyway, Yu Bin really hopes that there is a way to get these royal guards to leave the territory to participate in the battle, after completing the construction of the secret law sanctuary, Yu Bin took a look at the attributes of these royal guards, which really made him want to hug it and not let go.

Almost more than 300,000 blood, all the offense and defense are more than 3,000, the level is 180 with the sixth-order cap, plus the full set of exclusive suits for the king's guards they wear, "Indomitable Heroic Soul", it is really a bulldozer that blocks and kills people, and the Buddha blocks and kills Buddhas, and the two-meter-high humanoid gundam ah!

If you can let such a humanoid killer go out for a spin behind him, Yu Bin promised, don't dare to say anything else, it would be easy to slaughter a town with a population of less than 2,000, no matter how many players you come to defend, just the King's Guard up to fifty points of damage reduction is enough for him to ignore those players who are generally second and third order. In other words, with a full three-order level suppression and a defense reduction of more than three thousand armor, it is still a question whether those players can deal forced damage on the King's Guard.

It's a pity that Yu Bin can only watch these tough guys drool!

After cleaning up his unwillingness, Yu Bin walked into the tall obsidian building.

The space on the first floor is the largest, which is arranged as a library by Yu Bin, and all kinds of books and academic scrolls scavenged from Mosso Black City are stored here in different categories for the residents of the territory to read, and there will be restrictions on opening to players who come to Naxxramas in the future, and more than a dozen Naxxramas residents with good wisdom serve as librarians here, they all have reading or writing life skills, two of them also have rudimentary magical knowledge, Yu Bin put them here for key training, It is hoped that a scholar or mystical apprentice will be produced from within.

Walk up the stairs to the second floor, and enter an empty room, the floor of the room is depicted with a complex magic array, there are some tables and chairs around the wall, and there are some bottles and cans and alchemy equipment on the table, this room is set up by Yu Bin as an alchemy workshop, and the alchemy workshop of ordinary functional buildings is different, it is only used to develop new alchemy formulas and potion formulas, and is not used for batch production, after all, Yu Bin does not have the ability to obtain all the formula drawings, and some formulas can only be developed by themselves.

The three floors are similarly furnished, the only difference being that there are no tables and chairs around the walls, and instead there are small worktops and tools, which are used for enchantment, inlay, and magic solidification.

According to Yu Bin's plan, the first to third floors will be gradually opened to players who are resident in Naxxramas in the future, and by charging a certain fee, players can use these items and magic arrays to develop recipes, enchant their equipment, inlay gems, and solidify magic.

The space on the fourth floor is obviously much smaller, and if you want to enter here, you can't rely on stairs, you can only enter through a fixed teleportation array, and people who have not been authorized by Yu Bin can't enter here. In the space of hundreds of square meters, dozens of exquisite shelves are displayed in an orderly manner, and the shelves are stored with various scrolls, which are the places used by Yu Bin to store the magic and skill scrolls, which are also the trophies obtained from his adventures in the dungeon, and some of them are exchanged from Kel'thugad.

The space on the fifth floor is even smaller, with only a room of less than 100 square meters, and the walls of the room are covered by bookshelves, which are stacked with books and manuscripts of different thicknesses and sizes.

In the center of the room was a desk, and the magic chandelier on the roof provided enough light for the room to be seen as a figure hidden in a cloak crouched on the desk and writing a book, and the only sound of quills brushing and moving on parchment could be heard in the silence of the room.

Yu Bin's appearance obviously woke up the figure who was immersed in writing, only to see him raise his head and look at Yu Bin, under the light of the chandelier, you can clearly see that inside the cloak is a skeleton with a dark blue soul fire in its eye sockets.

"Old friend, how's it going? Are you still happy here? Yu Bin approached the other party with a smile and said.

"Very good, I think, for a prisoner, there is no more to hope for." Martan Golden Coffin said in a faint tone, as if he was commenting on a person who had nothing to do with him, "Your Excellency Lord has come here to check my progress?" ”

That's right, this skeleton is the Lich Maltan Golden Coffin!

After Maltan escaped from Sebrigark using space items, the lich did not immediately return to Elvia, and Maltan, who still did not give up his revenge, hid, wanting to take advantage of the turmoil in Mossoblack City to complete his revenge.

However, the rapid change of the whole situation greatly exceeded Maltan's expectations, after a series of dazzling changes, Yu Bin achieved his goal at a very fast speed, and the entire Mosso Black City returned to the control of the Black Dragon Queen.

Just when Maltan thought he would be killed by Yu Bin like the dark elf Vidara, or given to Kel'thugad as experimental material and slave, the man he hated most, the damned little undead, Ice Whisper Dry Bones, changed his fate once again.

Yu Bin personally asked Elvia for Maltan, although as punishment, Sinisterra deprived Maltan of most of his strength, and personally set a prison for this lich who inherited the mantle of the great wizard Gryman, making Maltan become an "ornament" with no academic and knowledge, but no fighting ability, but Martan survived after all, and did not have to face the cruel ending of eternal death.

After that, Maltan was transferred to Yu Bin by Elvia, and after returning to Naxxramas, he was appointed by Yu Bin as the chief advisor of the territory, responsible for alchemy, enchantment, witchcraft, etc., and also asked him to transcribe the knowledge of the great wizard Griman as much as possible, and put it in the library as a reserve for the territory.

Knowing that the lich in front of him has not given up his hostility and revenge, Yu Bin had to secretly smile bitterly, in fact, if Yu Bin had other better options, he would never keep this guy Martan by his side, although he believed in Sinestra's ability, after being deprived of his strength, Martin definitely had no strength to hurt him, but this did not mean that he was willing to let such a lich who was a mortal enemy of himself occupy a high position by his side, God knows what tricks this guy would play secretly.

But Yu Bin really has no other choice. Although the adventure in the underground world has brought him great gains, it has also made the problem of the territory more serious, the main problem is that so far, there is no assistant with enough ability to help Yu Bin manage this territory.

Don't think that a territory only needs to build buildings and recruit troops, this is not the kind of third-rate game. The problems encountered in the development of a territory can simply drive people crazy, the direction of the development of the territory, the living requirements of the residents, the training and garrison of soldiers, the development of the economy and the reserve of resources, the cultivation of talents and the goals of military operations, and so on!

If Yu Bin recruits all kinds of players to help manage the territory like those big guilds in his previous life, then these problems will be solved to a certain extent, players who are good at economic development are responsible for managing the business planning of the territory, players who are good at leading soldiers are responsible for training soldiers, and players who are good at coordinating relationships are responsible for dealing with various requests from residents, and so on.

But it's a pity that Yu Bin neither has the capital of those big guilds, nor is he willing to let a large number of players enter the management of the territory like those big guilds, so far, only Alan has hung the name of deputy lord in Naxxramas for special reasons, and even Lei Guang and Keldila do not have a definite position.

Therefore, Yu Bin is in great need of an assistant to help him manage the territory, and since it is impossible for the player to take on this role in a short period of time, he has to find an NPC.

And Maltan just meets Yu Bin's requirements, first of all, as a former high-ranking official of the Virgil Kingdom, Maltan's ability cannot be bad, not to mention, after inheriting the inheritance of the great wizard, Maltan has been lurking in the Virgil Kingdom for a long time in order to take revenge, and has raised a huge army, and almost succeeded in realizing his revenge plan.

Secondly, Maltan is a lich, or a lich who inherits the legacy of the great wizard Gryman, and this identity means that Maltan's sorcery attainments far exceed those of players, and even more advanced than ordinary mage heroes, otherwise, this wealth lover and coward would not have succeeded in the lich profession.

A mage-type high-end talent who can not only help him manage his territory, but also be responsible for researching magic and alchemy recipes and enchanting skills! Where to find such good employees?

Obviously, no one else has the ability to do this!

Therefore, how could Yu Bin watch Maltan slip away from his hands, originally in Yu Bin's eyes, Vidara may be a better choice, this dark elf assists Elvia in managing Kodila City, which is very suitable in terms of ability and qualifications, the problem is that Vidara is the chosen one of the spider goddess, and after her identity was discovered by Yu Bin, it is doomed that this dark elf will not survive anymore.

"Ha, well, old friend, I don't think we can sort out the grievances between us in a few words, and I don't expect you to give up your anger and become my loyal assistant!" Yu Bin propped his hands on the desk, put his face close to Martan's skeletal face, and said, "In that case, let's make a deal!" As soon as you complete this transaction, I will set you free, and I will ask His Majesty Sinestra to lift your bondage, of course, I can't help you if you are deprived of power. ”

Although he couldn't restore himself to his original state, Yu Bin's words still gave Maltan hope, and the soul fire in his eyes beat violently obviously.

"What deal?" "Whatever the deal, you must swear in the name of the Lord of Death, or I would rather be trapped in this room forever as I am now, cursing your death!" ”

"No problem!" Yu Bin agreed without hesitation, "You should believe in my sincerity, old friend!" ”

"Your sincerity? Is your sincerity to take everything out of me? Maltan said with a sneer.

"At least, in the relationship between the two of us, I wasn't the first to break this relationship of trust, didn't I?"

"You! Despicable fellow, even if what you say is true, that's what you forced me to do! Maltan gritted his teeth.

Yu Bin spread his hands: "I think, it's pointless to argue about these things now, at least I saved your life three times before and after, didn't I?" Okay, let's talk about trading! ”
