As a thief, Song Zheng can still occupy a lot of advantages when sneaking up, especially since he also has the 'Shadow Cloak' such a sky-defying skill, and he can often unexpectedly exert a huge effect when facing mages, and he has relied on these abilities many times before to kill mages who are far more powerful than him.

However, if the opponent's strength is too strong, even with the Shadow Cloak is likely to fail, especially since these necromancers' defenses are far stronger than ordinary mages, and it is difficult to kill them with one hit.

Especially now that he is still in the opponent's mage tower, it can be said that he is in the opponent's home field, and no one knows how many traps the necromancer has placed in this mage tower before.

"Do you want to use the 'Killing Feast' directly to fight him, if you can't kill him, then there is only one way to die......" Song Zheng was uneasy in his heart.

Mages have too many life-saving skills, such as magic shields, petrified skins, flashes, ice barriers, etc., which can almost defuse the sneak attack of thieves, and necromancers don't want to have many physical points like human mages.

If the other party has already been transformed into a lich, then it is not to mention, although he also killed a lich in the psychic tower before, but it was not his personal ability to kill the lich in an instant after hundreds of warlocks attacked together.

"Do you want to risk using that 'Cataclysm' skill?" Song Zheng couldn't help but fall into distress as he looked at the skills on his attribute panel, with his current ability, it was too difficult to rescue Catherine from this mage tower.

But when his gaze fell on a string of numbers, he was suddenly dumbfounded.

"This ...... How much is that?! One, ten, hundred, thousand, thousand, thousand, one hundred thousand, million...... Ten million ......" Song Zheng widened his eyes and silently counted the numbers one by one, only to feel that his whole body was trembling, and his throat was also dry.

What was originally only nearly a million experience points turned into tens of millions!

"Yes...... It must be the meteor that was summoned earlier! Song Zheng's heart moved, and then there was an uncontrollable excitement.

Although the magic scroll was not made by him, it was the one he used to open the seal, and it seemed that the mysterious system should have attributed the meteor magic to him, which led to all the experience finally gained being counted on him.

It's a sizable city, with tens of thousands of undead defenders, and thousands of meat grinders and a large number of abominants and elite ghouls boarding the docks.

After all the experience was gathered on him, the result was more than 50 million experience points in front of him!

"You can upgrade a lot of levels now......" Song Zheng only felt that his legs were trembling, and hurriedly and quietly hid at the foot of the wall of this mage tower, so as not to accidentally expose his figure in the excitement.

This is completely from a beggar to a multi-millionaire, and he has been struggling with which class to put the little experience he has accumulated so hard to put on it, but now he can use it at will, even if the three classes are upgraded together, he can improve by more than ten levels.

"Let's take a look at the two-level thief class first, and hope for some good luck." Song Zheng quickly made a decision.

Thieves are still his old profession after all, and he is most familiar with this profession.

However, when he invested millions of dollars, he couldn't help but be speechless when he looked at the newly acquired skills.

"Pistol shooting? Isn't this the latest Fanatic's skill, which can also be obtained? But you need to get a pistol first......"

Song Zheng had a pistol before, and he bought it from the dwarves, the quality was quite good, and it had played a great role in the initial battle, but later due to the exhaustion of gunpowder and bullets, he gave up using the musket, and after his level was raised, he never used the musket that was very inconvenient to reload.

At the moment, this 'pistol shooting' skill is undoubtedly useless, and it can only be done in the future when a powerful musket is found.

There is no shortage of guns in the world of Azeroth, dwarves and gnomes should be able to make them, of course, the best guns must be made by the Titan Guardians, which need to be obtained from Uldaman and even Ulduar.

Song Zheng naturally had no chance to go to the Titan ruins like Uldaman at the moment, so he could only invest in experience again to level up.

But this time, the new skill made him jump even more.

"Bribery? This...... Do you need professional skills for this kind of thing, as long as you have money, who can't do it......"

Song Zheng resented in his heart, this random way of obtaining skills was too tricky, and there were too many skills of thieves, including a lot of messy skills, and it did take a certain amount of luck to obtain powerful and useful skills.

"Forget it, let's try other classes first, and see if the luck of this warlock class will be better, if you can learn to summon Hellfire or Doom Guard, then you will be developed."

The level of the warlock profession is still low, and the experience required is less, but when it is upgraded, the corners of Song Zheng's mouth twitch when he looks at the new skill.

"Summon the Voidwalker...... Is this blue fat? This is too far from Hellfire, even if you get the summoned succubus, it's okay......"

The Warlock's Blue Fat is actually very useful, but it is mainly used for defense, and it is not very useful at the moment.

Song Zheng could only grit his teeth and continue to invest in the warlock profession.

As the level rises again, new skills appear.

"Making Healing Stones...... Do you have this skill too? What will this healing stone look like when it is made...... Can it really be eaten like sugar? Song Zheng couldn't help but be stunned when he looked at the new skill.

In the game, the healing stone restores health, but I don't know what the effect of the healing stone will be in the real world, maybe it will be some kind of medicine used to heal the wounds.

This should be considered a useful thing, at least to save your life in times of danger, and most importantly, to be traded.

However, this is still of little use to rescue Catherine, and he can only hope for the next time.

When the level was raised again, Song Zheng looked at the new skill but was already in despair.

"Demon Portal...... Now the sugar and the door are there...... It's not going to be '' next. ”

This demon portal should be very useful in many cases, and it may also be used to escape, but what he lacks most now is combat skills, if he can't defeat the necromancer in this mage tower, there is no chance of escape.

"It seems that today's luck is very bad, but fortunately, I have enough experience points, so I can try this shaman profession again......"
