The choice of Tier 5 classes is much simpler.

Whether in the past or in the future, the Corpse Witch has never lost its important position in the undead since its birth, as a representative of the proficient necromancer, the name of the Corpse Witch is not used by any necromancer, only those who have great strength and profound knowledge can call themselves Corpse Witch.

As a representative spell of the Death Witch, the Necromancer Mystery Spell, which covers a small area in a very short period of time with a large concentration of high concentration of death power, has become synonymous with the Death Witch, and many life races regard it as the Death Witch's specialty, and even consider this spell to be the highest achievement of the Necromancer.

As a result, the Corpse Witch has become one of the most powerful pillars of the undead standard system, and together with cheap undead cannon fodder, it forms the basis of the undead military power. It can be said that most of the tactics of the undead are developed around these two pillars.

Whether it is a 3rd order gargoyle or a 4th level necromancy, it can be said that its combat goal on the battlefield is to create a stable and safe output environment for the corpse witch, which can also be seen that the corpse witch occupies an important position in the entire undead military system.

For such an important class, Yu Bin certainly will not take it lightly.

The first tomb of Naxxramas to be used to cultivate corpse witches was built by Yu Bin when he returned from Mosso Black City, and since then, Yu Bin has never stopped planning to expand the building, so far, four complete tombs have been built, and a fifth is under construction, and a steady stream of dark mages have been recruited and thrown into these tombs to learn the corresponding knowledge under the tutelage of Maltan and Tarsis until he becomes a qualified corpse witch.

Despite this, the number of corpse witches in Yu Bin's hands is not enough for him to be satisfied, mainly because Naxxramas does not have enough time to develop, unlike other troops, corpse witches need time the most, although the undead have a long life, but this cannot replace the part that needs to be consumed in the process of growth.

In order to make up for the gap caused by the lack of the number of corpse witches, Yu Bin replaced some of the duties of the corpse witches with the shadow spiders he obtained from Mosso Black City. Under the leadership of the spider mother Azakne and a group of spider girls, the spider demons produced and hatched by the dark demon spiders from Mosso Black City are generally 4th to 5th order strength, and when these spider demons evolve to the top ebony spiders or death spider guards, the shadow magic they master also replaces the death suspicion of the corpse witch to a certain extent.

Of course, with the continuous increase in the number of corpse witches, Yu Bin will eventually return to the fighting method with corpse witches as the core, after all, compared to the spider army with a small base and insufficient stamina, the corpse witches who have a complete evolutionary chain and can learn independently can better meet Yu Bin's requirements and provide strong support for the upcoming and continuous wars in the future.

Finally, there is the 6th level of troops, and at this level, it is no longer something that Yu Bin can pick and choose. Tier 6 and Tier 7 troops are already considered elite for a lord, or even killer or the like, and under normal circumstances, having one is enough to steal fun, where can you still pick and choose.

There are two types of 6th-order troops in Yu Bin's hands now, one is the skeleton warrior as the standard system of the undead, with the nightmare stable obtained by Yu Bin from the Wanyuan Plain, and can eventually evolve to the nightmare knight, although it is much worse than the final form of the abyss knight or the king's guard, but it is also a relatively powerful 6th-order army, and the combat power is enough to compete with the human guardian knight.

The other Tier 6 class is a mutant class known as the Dark Spider. The dark spider spirit comes from the spider mother Azakne and those who were brought back to Naxxramas by Yu Bin, I don't know why, although the strength of Azakne, who was resurrected by the soul suppression bead, has decreased a little, from the hero level to the pseudo-hero level, but it has regained the ability to lay eggs, and under the influence of Azakne, those life-spinner spider girls from groping Blake have also not lost this ability because of the erosion of Naxxramas's death power.

After hatching, the eggs laid by Azakne and the Spider Maidens will give birth to a creature that has been turned into a spider spirit by Yu Bin, which has the characteristics of both a spider girl and an undead, and can use both shadow magic and death power.

After a period of almost two months, spider spirits transform into humanoid creatures, with the appearance of ordinary dark elves not much different, but with eight thin, sharp spider legs growing on their backs. After growing, the dark spider spirits no longer have the ability to lay eggs, and their bodies have also lost the fat abdominal pouch unique to spider girls, but their abilities have entered the level of 6 levels, and at the same time, they have the intelligence required by the caster, and after a certain degree of teaching, they can even master a large number of shadow and death spells.

But because of the small number of spider girls, the growth rate of the dark spider spirit is also very low, and so far Yu Bin has only accumulated less than a hundred dark spider spirits. Thankfully, since they were born in Naxxramas, the Dark Spider Spirits were also able to enjoy the blessings of the territorial trait, which gave them a lot of strength to make them rank among the top Tier 6 creatures.

In addition to the above nearly twenty types of troops from the 0th to the 6th order, Yu Bin also has some special soldiers in his hands who are scarce but have good strength, some of these special soldiers are cultivated in special ways, and some are recruited by Yu Bin from specific places through the memories of his previous life.

Among them, the most important thing for Yu Bin is the Demon Bone Dragon Cavalry transformed by relying on the Demon Bone Dragon Horse, due to the lack of qualifications of the White Bone Cavalry as a material, Yu Bin's existing Demon Bone Dragon Cavalry can only reach level 5 and level 100. Despite this, the transformed Demon Bone Dragoons are comparable to the 6th order troops in terms of attributes and combat effectiveness.

In addition, there is also a pseudo-7th-order class created by Yu Bin through special means - Dragon Devouring Spider!

The reason why it is called a pseudo-7th order is because the attributes of this creature have reached the standard of the 7th order, but the combat effectiveness is not comparable to that of the 7th order. But for players at this stage, a dragon eater spider is enough to make them feel hopeless!

The appearance of the dragon devouring spider is completely the result of Yu Bin's unbridled imagination and wealthy background. Remember the batch of Void Dragon Eggs he brought out of the secret room in Blackstone Mountain? In fact, the number of Void Dragon Eggs cultivated by Onexia in the secret room exceeded a hundred, most of which lost their life reaction, and the remaining relatively intact dragon eggs were only about twenty, Yu Bin selected the largest of them, and used the time gravel to catalyze it into the world's first Void Dragon, and the remaining Void Dragon Eggs were packed by Yu Bin and brought back to Naxxramas.

Later, for the purpose of research, the Seventh Apostle Professor took three Void Dragon Eggs from Yu Bin's hands, and the remaining dragon eggs were stored in the Spider Crypt by Yu Bin, and he couldn't figure out how to use these things for a while.

Let's continue to cultivate, relying on the technology and resources mastered by Yu Bin alone, it is simply not enough to meet the requirements for the continued development of the Void Dragon Egg, but if it is broken and the egg whites and yolks in the dragon eggs are directly drunk, Yu Bin feels that it is too wasteful.

Before he could make a decision, Yu Bin had to go to the Wanyuan Plain, and when he returned, he found that the Void Dragon Egg placed in the spider crypt seemed to have caused some unexpected effects.

Some spider eggs close to the dragon egg were mutated under the influence of the aura emitted by the dragon egg, and the final hatched spider demon was more aggressive than ordinary spider demons, larger in size, tougher in epidermis, and even with a trace of undetectable dragon power, and these spider demons had no interest in ordinary food at all.

After trying a variety of food types, Yu Bin finally decided that these spider demons only eat meat with dragon blood, such as bipedal wyverns and other wurms are their favorite, and even after these spider demons have grown to a certain level, they can also independently prey on a bipedal wyvern.

After these spider demons stopped growing, Yu Bin determined that these guys had broken through the original growth limit and reached a standard that was extremely close to that of a seventh-order creature, and there was no doubt that it was the existence of those Void Dragon Eggs that made these spider demons who could only grow into a fifth-order become what they are now.

Yu Bin named these special spider demons Dragon Eater Spiders, and fed various wurm creatures to see if there was a possibility of further evolution of these Dragon Eater Spiders, and at the same time, he scattered the Void Dragon Eggs in the various spider egg cultivation rooms in the spider crypt, and ordered the spider girls to take care of them carefully, trying to further increase the number of Dragon Eater Spiders in this way.

The only thing worth worrying about is that the power contained in these Void Dragon Eggs is not infinite, and one day, as the power is exhausted, these Dragon Eggs will completely lose their life reaction, and the Dragon Devouring Spider will no longer be able to be born.

This is one of the reasons why, shortly after, the Snake of the Flesh spared no effort to capture the Black Dragon's lair on the Black Coast, where he set up an ambush and captured the Black Dragon Princess Onexia. On the one hand, Yu Bin hoped to find information on the cultivation of Void Dragon Eggs from Onexia's lair, or more Void Dragon Eggs, and on the other hand, he was unwilling to let the black dragon continue to wander outside, constantly stimulating Nefarian and Sinestria's already tense nerves.

By October 342, Yu Bin already had an extremely impressive, even huge military force.

The total number of Tier 0 troops exceeds 200,000, of which 160,000 are for the White Bone system and 40,000 are for the Skeleton system.

The total number of Tier 1 classes exceeds 120,000, most of which are ghouls, and the number of zombies and corresponding evolutions is less than 10,000.

The total number of Tier 2 troops exceeds 90,000, mainly crypt spiders, and ghosts account for less than one-fifth.

There are more than 50,000 Tier 3 troops, almost entirely composed of gargoyles, and there are nearly 10,000 carved statues stored in Naxxramas.

There are more than 20,000 Tier 4 classes, of which 10,000 are Necrons and their evolutions, and the rest are made up of Plaguebringers and Frightened Dead, as well as a small group of Golems.

The number of Tier 5 troops is much less, even with the addition of dark mages who are still training, the total number of soldiers in the Corpse Witch line does not exceed 6,000, while the total number of Spider Legions, including Spider Demons, is about 20,000.

There are less than 1,000 Tier 6 troops, and most of them are skeleton warriors who have been recruited for less than a few months.

The total number of Tier 7 Dragon Eaters is 23.

These undead armies totaling nearly 400,000 are the most important military force in Yu Bin's hands, and they are also suppressing the entire Naxxramas, so that players dare not rely on any rash actions.

In addition to these soldiers, the Knights of the Black Blade led by La Suvios have also developed a lot, from the initial 4,000 people to the current 25,000 people, divided into 5 knights, one of which is a heavy knight order equipped with heavy armor.

In addition, Naxxramas also has 5 hero-level combat power and 2 pseudo-hero-level combat power, and in terms of high-end strength, it has even surpassed the ordinary noble lords of the aborigines.

As a nobleman, especially a nobleman who has participated in bloody battles and received medals, Yu Bin can also recruit resident players in the territory to fight, and the recruited players or groups of players cannot refuse, unless the other party is willing to pay a high compensation and move out of Naxxramas from now on.

This power alone is enough for Yu Bin to obtain a legion of nearly 100,000 players again, even if these players need to be provided with weapons and equipment due to the lord of Bin, but the strength of these players themselves is comparable to a legion composed of aborigines.

And these are just Yu Bin's existing strength, once the war breaks out, relying on the strong economic strength of Naxxramas, Yu Bin can also use gold coins to recruit a large number of players to fight.

The Angel's Covenant is due to the rebellion of the Armas Empire, and it does not hesitate to spend hundreds of millions, or even billions of gold coins, to recruit millions of players, and Yu Bin will naturally not give up this power. With the strong economic strength of Naxxramas, not to mention more, recruiting 500,000 players is not a difficult task for Yu Bin.

If you add the hunting regiments controlled by Yu Bin, as well as some guilds controlled or influenced by the Devouring Snake, this number can be doubled!

It can be said that the accumulation of the past four years has finally long since Yu Bin's strength at the moment, whether it is personal or territorial, and even what he directly controls and indirectly can influence. It is this four-year hard work, continuous birth and death, that allows Yu Bin to master such a huge power.

And this is the reason why Yu Bin dares to face the camp war that is about to break out!
