At the beginning, in the underground of that dark swamp, guilds such as the Fifth Legion, the former Alliance, and the Temple of War used to use the terrain to fight against Skeletron's army, but Skeletron at that time should have set his goal on the regular army of Lianzhou City that arrived later, and it was just a casual response to the player.

But at this moment, it should be doing its best, the ground under his feet, the roof of the cave above his head, and even the surrounding cave walls are constantly pouring out zombies and skeletons, covering the sky like a dark frenzy.

Since both sides of the battle are undead, they almost have no sense of fear at all, even if they have been seriously injured and only half of their bodies are left, they are still frantically attacking each other.

Judging from the scale and difficulty alone, this can definitely be regarded as an epic task, and Su Yan only hopes that the reward for this task will not be too cheating.

He had been constantly using the [Dark Corpse Technique] to control the zombies and skeletons that rushed in front of him, and soon it had reached more than a hundred, tightly protecting himself and the little nun in it.

"Is this a great battle in hell......" The little nun began to pray with her pale eyes closed, gesturing the cross on her chest.

Mingyue was on a rock not far from Su Yan, her white dress was particularly conspicuous in the dark, at this moment she still closed her eyes slightly, chanting strange spells in a low voice, and black light continued to linger around her body.

And the more than ten evil spirit corpse kings were also covered in black light, blocking Mingyue's body.

Those powerful corpse kings finally rushed to the front of them, and immediately collided with those evil spirit corpse kings. Large swaths of the mine collapsed in the impact.

Although the number of attacking corpse kings is large, the level is mostly around seventy or eighty levels, which is far inferior to these hundred-level evil spirit corpse kings, so they do not have any advantage in a small area.

Su Yan relied on the many zombies under his control to intercept them, and forcibly controlled the corpse king who rushed to his side, with his current level and the level of the [Dark Corpse Technique], he could already control the ordinary corpse king for more than 3 minutes.

With enough vitality, this 3-minute interval can already allow him to control dozens of corpse kings non-stop, but he was a little surprised to find that he couldn't summon Wind Yinxiao!

"Did that guy hang up?" Su Yan's heart sank, because he had been in trouble, it seemed that he had not taken it back after the secret passage of the shadow let the wind laugh.

In normal times, hundreds of zombies and dozens of corpse kings must have been an extremely powerful force. But now he is facing the charge of thousands of corpse kings and tens of thousands of zombies and skeletons. His army of the undead was incomparably smaller.

"I don't know when I will have the ability to control thousands of troops......" Su Yan couldn't help but sigh secretly, judging from the number of undead monsters alone, the strength of the Skeleton King should be close to that zombie veteran, maybe this is the strength that the real Undead King should have.

Due to the participation of many corpse kings. Although Su Yan and Mingyue can resist locally. But judging by the entire underground battlefield. Their side is at an absolute disadvantage.

However, soon Su Yan finally saw the power of the formation arranged by Mingyue, and those lingering black lights could not only strengthen the zombies, but also almost resurrect the zombies who died in battle.

Scattered on the battlefield, fallen evil spirits and zombies continue to get back on their feet. In the end, it was in this way that he blocked the crazy attack of the thousands of corpse kings and countless skeletons.

Relying on the strength of the dark formation, the battlefield quickly fell into a stalemate stage, and then as time passed, the advantage slowly tilted towards Su Yan and Mingyue's side.

However, Su Yan was getting more and more nervous in his heart, because the Skeletron King still hadn't appeared yet!

That's the real enemy, and no matter how many skeletons and zombies you kill in front of you, it's useless if you don't kill Skeletron.

Su Yan looked at Mingyue, and saw that she was also expressionless and continued to chant the incantation, obviously not taking the situation in front of her as a victory.

At this moment, as a terrifying coercion spread rapidly in the darkness, Su Yan's heart trembled, and he immediately knew that it should be the Skeleton King who had finally come in person!

"Mingyue, do you want to rely on these little characters to deal with me? You're too self-conscious! Skeletron's majestic voice resounded throughout the underground cavern, and even recalled it directly in his head.

Su Yan followed the prestige, and in the darkness he saw that the Skeleton King was still wearing heavy armor, wearing a crown and holding a rusty heavy sword.

And with its appearance, the strength of those skeleton generals was also suddenly strengthened, and they could completely compete with the evil spirit zombies who were more than eighty levels and had been strengthened by the formation at a level of sixty or seventy.

"Hmph, it's you who can't measure your strength, your strength is not enough to surpass this world, but you vainly want to use the power of an artifact to leave from the gate of the other world, no one will care about you if you find your own death, but the dark crown must stay!" Mingyue finally opened her eyes and sneered.

"Ha Luha, it's your business if you want to stay here and survive, if you want the dark crown to come and get it, you ran away last time, I see where you can run this time."

Skeletron sneered, the black light on his body burst out, and at the same time, the huge long sword in his hand was raised, and the whole person had rushed towards the bright moon like a black lightning.

Su Yan watched this scene from a distance and couldn't help but be secretly frightened, the weapon of the Skeleton King is said to be a part of the Qiankun Divine Sword, even if he doesn't know the specific attributes of the Dao, but it is definitely an artifact, and most of them are still high-grade artifacts that are no worse than the dragon pattern, with Mingyue's delicate appearance, it should be difficult to compete head-on.

Mingyue really didn't fight head-on, but scolded coquettishly, and immediately several evil spirit corpse kings were in front of her, forcibly blocking the skeleton king with their bodies.

Although the Skeleton King's attack was fierce, in the face of this evil spirit corpse king with a health value of up to 6,000,000, Su Yan didn't believe that he could directly kill him in an instant.

Sure enough, the 'black lightning' that the Skeletron King turned into was immediately entangled by those evil spirit corpse kings, and although the rusty giant sword flew up and down, the attack of each sword was as high as more than 100,000, but it still took a lot of time to kill these evil spirit corpse kings.

Su Yan couldn't help but breathe a sigh of relief, and was about to control his 'army of the undead' to quietly step forward to help attack Skeletron, but unexpectedly, the Skeletron King was under siege by the Evil Spirit Corpse King, and he quickly let out a strange laugh. (To be continued......)
