As the battle continued, undead creatures continued to arrive from all over the world to rescue the tower.

There was even a huge crypt spider, which should be another undead boss in the city, and everyone had to fall into a bitter battle.

Su Chen himself had to join the battle with Frost Sorrow in order to protect the elven rangers beside him who were not very good at melee combat.

However, to his surprise, Katrana beside him was facing more and more undead creatures, but she was more and more excited, not only casting all kinds of powerful fire magic, often blowing up a large pit of more than ten meters, and even out of nowhere she made a giant sword with a hideous shape, only the blade part was more than two meters long, and even played hand-to-hand combat with slashing and chopping, and the sword also had flames attached to it, and the attack power was extremely amazing.

"I'm afraid this guy's combat power is the highest in our place...... Well, she must have hidden some of her strength, so her true combat power is estimated to be able to destroy Stratholme alone......" Su Chen's face darkened a little, it was impossible for a strong person like this to be unknown in Azeroth, and it was obvious that her previous name must have been just a pseudonym.

Su Chen's heart silently slipped through the names of a group of Azeroth powerhouses, and finally when an extremely familiar name appeared in his mind, even his hand holding Frost Sorrow couldn't help but stiffen.

Onexia ...... The name of the black dragon, which was so famous in the World of Warcraft, was so familiar that he ignored that the black dragon princess had other names.

She is good at fire magic, likes to wear black, has violent tendencies, and has the name of a fake nobleman, all of which are quite consistent with the identity of the black dragon princess.

"But how did she come to Lordaeron and pretend to be an adventurer to help me?" Su Chen looked at Katrana, who was in the distance as if she had entered a no-man's land, and rushed to the Baroness Annastari with a giant sword in her hand, and couldn't help but feel extremely confused in her heart.

In the history of Warcraft, Arthas doesn't seem to have much to do with the Black Dragon Legion, and Onexia should soon go to Stormwind City as a fake nobleman.

But now she uses the name Catlana Presto to pretend to be an adventurer to help her attack Stratholme......

Su Chen didn't think that his charm was strong enough to attract this black dragon princess to take the initiative to come and make promises.

Although he is the prince of Lordaeron, there is not much difference between Lordaeron and Destruction at this moment, he has almost nothing in his hands, not to mention that even the identity of the prince of Lordaeron in his heyday is nothing in front of the identity of the Black Dragon Princess.

After all, even though Deathwing has fallen, the Black Dragons are still a guardian of the dragons, and their status and status are far above humans.

With the near-eternal life of the guardian dragons, she could simply watch the rise and fall of the human kingdom from the sidelines......

An excited shout interrupted Su Chen's thoughts, and when he looked up, it was Katrana...... Or maybe Onexia had slew the Baroness Anastari with a flaming greatsword.

Seeing her black hair fluttering and excitedly brandishing the flame giant sword and rushing towards the spider boss not far away, Su Chen was completely speechless.

For her, the princess of the Black Dragon Legion, this kind of battle is almost like a game.

However, although I don't know what her purpose is, this psychic tower is really occupied at the moment.

Without the enhanced effect of the Psychic Tower, the surrounding undead troops are almost vulnerable, and they can no longer be resurrected quickly.

"What battle damage do we have?" Su Chen came to the tall psychic tower, and even though the gloomy tower had ceased to function, standing in front of its door still brought a chill to the bone.

"It's just the loss of a few Death Knights' minions, and while this tower strengthens those undead scourges, it also strengthens our ......," Uther whispered.

Although he and the Death Knights are free from the Lich King's control, they are still undead creatures at heart.

Katrana Presto also stepped on the tower, and after the battle just now, her status in the team has obviously improved a lot, and many fighters have taken the initiative to make way for her.

Su Chen looked at the black dragon princess with complicated eyes, at this moment she had already put away the hideous appearance of the giant sword, regained the noble and elegant aristocratic image, and looked at the extremely complex structure inside the psychic tower with admiration.

"The structure of this psychic tower is really unique, although it is somewhat similar to the magic hub of the mage tower, but it is much higher in terms of the collection and conversion rate of magical energy, of course...... This psychic tower can only collect dark magic, which has great limitations, but this thing seems to have never appeared in Azeroth before, and it should be newly created, which is also very remarkable. ”

Su Chen didn't expect that she really had a very high opinion of magic, and just by looking at it, she figured out the structure of this spiritual tower.

It seems that because of their long lives, those dragons can't help but be strong in their own strength, and their knowledge is far above that of ordinary people.

"Your Highness, we have found a lot of crystals like this in this tower." Just then, Bridget walked out of the tower with something strange in her arms, and after killing Baroness Annastari, she led a group of paladins into the tower first.

Su Chen stared at it, only to see that she was holding several black crystals that were the thickness of her arm, and two of them even continued to emit a strange black glow.

"These are shadow crystals, a kind of magic crystals, which can be used to store magic power, these shining crystals contain a lot of dark magic, presumably it is the dark power collected by this psychic tower, this shadow crystal full of magic can at least resurrect a necromancer hundreds of skeletons." Katrana took the initiative to introduce.

"The forces of darkness? Then we'll destroy these things at once! Brigitte Abydis said as she swung her sword to smash the glowing shadow crystals.

"Wait......" Su Chen hurriedly stopped, but he was a little hesitant about whether to destroy this psychic tower and the shadow crystal immediately, the reason was very simple-he also needed energy!

"Can you use these shadow crystals?" Su Chen quietly asked Zhi Brain Xiaohei.

"No problem, no matter what kind of attribute the magic is just the outward manifestation of energy, to me it's like different flavors of food, which will eventually be transformed into pure energy, but ...... The use of this dark energy may have some effects on your body. ”

Su Chen's heart couldn't help but sink when he heard this: "Will it have an impact on my body?" What kind of impact is it? ”

"Of course, it will make the body biased towards a dark constitution, which may affect the use of the power of the Holy Light."

"......" Su Chen couldn't help but be a little speechless about this, his main combat power now is relying on the power of the Holy Light, if he loses the power of the Holy Light, with his current combat power of about 130, it is just the power of an elite knight.

"Will using these Shadow Crystals allow you to reopen the Sunwell?" Su Chen asked with some apprehension.

Every time he thought that the sun well he had gotten by sacrificing his life and death had never been able to use it, his heart was full of 10,000 grass and mud horses galloping past.

"Of course you can, but if you want to reopen Level 5 permissions, you will need a lot of shadow crystals, which will cause irreversible shadow erosion to your body."

"How serious will the results be?" Su Chen frowned and directly began to inquire about the results.

"You may not be able to use the power of the Light altogether."
