Warlocks were also interested in the tower, especially as the dark energy that surrounded the black tower was a great attraction to them.

Therefore, when Song Zheng announced that he was going to attack the Psychic Tower, he immediately got everyone's approval.

Since the battle on the side of Andohar was fierce, no one knew how long this siege battle would last, so it was impossible to conduct a detailed reconnaissance of the target as before, and discuss the best attack plan together, so they could only launch an attack as soon as possible.

On the way, although they also encountered some undead patrol troops, but the number was not large, and it seemed that due to the fierce siege battle, most of the undead troops were drawn over.

While the army of millions of undead may sound terrifying, the city of Andorhar is also huge, and a full-scale siege will require most of the undead troops.

The warlocks easily dealt with the patrols along the way, and approached only seven or eight hundred meters away from the psychic tower, only to encounter relatively stubborn resistance.

The Undead Scourge is still very important to these psychic towers that can collect dark energy, even if the battle is fierce ahead, there are still many elite troops stationed near the towers, especially the incredible number of necromancers.

Song Zheng has already seen the power of these necromancers, most of them are composed of mages who have taken refuge in the undead calamity, and some of them have taken refuge in the undead calamity before they have obtained new shadow power and become necromancers, although their strength is limited, but once the number is relatively large, they can hide behind those ghouls and skeletons and release shadow arrows crazily, and their lethality cannot be underestimated.

In particular, many powerful necromancers can also resurrect the undead, which can greatly exert the advantages of the undead army.

Warlocks immediately retaliated with Shadow Arrows when they saw the Shadow Arrows unleashed by the other side, but they still had to use a wide range of magic such as Rain of Fire when dealing with the skeletons and ghouls that rushed wildly.

Song Zheng also used his bow and crossbow to shoot the necromancers who were hiding behind the ghouls from a distance, so as to mix up some experience.

After a period of fighting, the experience he had gained was almost enough to take him to the next level.

However, seeing that the experience required for upgrading was getting higher and higher, Song Zheng also became a little hesitant in his heart.

According to his original plan to focus on the development of a class so that he can master its various abilities, he originally chose the Rogue class, but now that he has spent time with Warlocks, he has found that Warlocks should be a good choice as well.

In particular, the Rogue class isn't very good at ranged attacks, which makes it difficult for him to mix up experience in large battles.

"Maybe it's time to develop the Warlock class, if you can comprehend powerful area skills like Rain of Fire or Corrosive Seed, then it will be much easier to mix experience in the future......"

The experience required to redevelop a new class is not low, like the current warlock class, the first level requires nearly 300,000 experience.

However, this is still a lot better than continuing to upgrade the thief profession, you must know that the current thief profession needs millions of experience to upgrade at every turn, and the experience points he has accumulated after fighting with the warlocks for so long are not enough to upgrade the thief profession to one level, but it is enough for him to immediately upgrade the warlock profession to two levels.

Song Zheng hesitated for a while, seeing that a large number of undead troops were turned into ashes in the fire rain of warlocks, and he could only rely on crossbows to shoot slowly one by one in order to mix up some experience, and finally he gritted his teeth and decided to put his experience into the warlock profession first.

"If you don't become a mage, then you can be a warlock first, you can use magic anyway, if you can learn the magic of a range attack, you will gain experience much faster in the future."

When he made a decision in his heart, Song Zheng immediately put the experience he had accumulated before into the warlock profession.

However, when the Warlock's class was upgraded, he looked at the skill bar apprehensively, but he only glanced at it, and he couldn't help but bared his teeth.

"Big ...... Cataclysm?! ”

Song Zheng is no stranger to this skill, this cataclysm can be said to be a powerful skill of a warlock, and it is indeed a very powerful area attack skill.

However, what the Warlocks were expecting was a pocket-sized version of 'Cataclysm', the full version of which was supposed to be cast by Deathwing when he returned, and the result was that it nearly destroyed Azeroth.

At this moment, Song Zheng looked at his newly acquired skills, and immediately fell into a contradiction - he was not sure whether the 'cataclysm' he had obtained was the full version or the pocket version.

Ever since he had seen Thrall's 'Earthquake Technique' outside of Nanhai Town, he had instinctively been a little worried about these legendary spells, after all, no one knew how powerful they really were.

If the cataclysm he obtained was the full version, then it would be impossible for Azeroth not to be destroyed by the undead scourge, but to be destroyed by himself in advance.

But behind that skill, there was no explanation, not even the mana consumption required to release it.

"Doesn't this spell require mana, or does it require stamina like a thief's skill?"

Song Zheng didn't believe that he could support the launch of a real cataclysm with his own strength, and if he forcibly used it, he might immediately kill himself.

After thinking about it for a long time, the final result was that he still didn't dare to use this 'cataclysm' skill.

In this way, I don't know if I should be lucky or unlucky to obtain this 'cataclysm' skill......

"I can only keep it for now, and try it again when I have a chance in the future."

Seeing that the warlocks had suppressed the undead troops in front of them and were currently approaching the psychic tower smoothly, Song Zheng hesitated for a moment before simply putting all the remaining experience points into the warlock profession.

As the level stats changed again, a new skill appeared in the stat screen.

However, this time, Song Zheng couldn't help but be a little speechless when he looked at the newly acquired skill.

"This ...... That's kind of saving me money. ”

Song Zheng sneered in his heart that the new skill he had acquired this time was 'Summoning the Fear War Horse'.

Although it is also a warlock's summoning skill, it is a mount that is summoned!

This skill is very useful in the game, especially in the early stages of the game, when many people can't afford to buy horses, and this skill can save a lot of gold.

But in this real world, horses are not hard to come by.

Of course, what is more important is that the appearance of the fear war horse is too windy, too peculiar, and can even be said to be terrifying, and it is impossible to ride in front of ordinary people.

"This nearly a million experiences have been wasted......" Song Zheng sighed secretly.

These two skills can't be said to be completely useless, but they are indeed quite weak in ordinary combat.
