"With Sylvanas's strength, since Kel'thugad is not there, there should be no one in this psychic academy who is her opponent." Song Zheng secretly thought in his heart, he didn't continue to sneak and walk, but hid in a corner to rest.

Sylvanas, as the Ranger General of Silvermoon City, is already in an outstanding state of identity and strength.

In the history of Warcraft, even Arthas was able to fight back and forth after encountering the fall, and it lasted for a long time before Arthas was killed by Arthas using Frost Sorrow.

You must know that Arthas should have been at the peak of the Death Knight at that time, and his strength was already on par with Illidan, and he was already invincible on the side of the human kingdom.

Even if Sylvanas's strength is not as strong as Arthas, he is already among the strongest, and has few opponents in the undead scourge.

Nowadays, most of the monsters in this psychic academy are skeletons and ghouls, and their combat power is not very strong, in addition to this, there are a large number of necromancers, and most of them are newly become necromancers, and their combat effectiveness can only be regarded as average, not to mention that the skills of the rangers seem to have a strong restraint effect on the mage.

Thinking about it this way, Sylvanas may be very safe now, even safer than Song Zheng himself.

"Looks like I should go to the ground and wait." Song Zheng's heart moved, since Sylvanas was likely to have nothing to do, then she would probably go out and join him later.

Thinking of this, Song Zheng immediately prepared to return along the same path, and then waited for Sylvanas with Catherine and Gianna.

However, to his surprise, there seemed to be a lot more undead around, and the doors of many passages were also closed.

This made Song Zheng a little worried...... The undead seem to have sensed something.

As he cautiously retreated along the road, passing by the hidden study of Kel'thugad, he found that there were a large number of people in the place that had not been guarded before.

"Oops, could it be that my theft in Kel'thugad's study has been discovered?" Song Zheng's heart moved, and he quickly figured out that there would be more and more undead guards encountered on the way.

He didn't dare to get too close, only to observe from a distance, and was ready to run away if something changed.

Just then, a taller lich stepped out of the study.

Since most of his body had turned to bones, he could no longer see his face at all, and only felt two red flames in his eye sockets jumping rapidly.

"It's damn that a thief has entered this psychic academy, and the most important thing has been lost...... When Lord Kel'thugad returns, he will be furious at the sight of such a scene, and immediately put everyone into a fighting state, and must find the thief no matter what! The lich's voice was full of anger and unease.

After receiving the order, a large number of undead immediately began to patrol the passages, as if they were going to rummage every inch of the psychic academy.

This also made Song Zheng secretly worried...... This will definitely affect his retreat.

"Who is this damn lich? It can't be Nales Frost Whisper......" Song Zheng's heart moved.

Les Frost is considered to be relatively powerful among the many bosses in the Psychic Academy, and his lich body also has a strong defensive power.

"If I can kill this Les Frost Whisper, then the experience I gain will probably allow me to take it to the next level." Remembering that he had killed Naserlin Kasdinov by sneak attack before, and gained a lot of extra experience, which allowed him to be promoted to the next level, Song Zheng couldn't help but feel a little excited in his heart.

Now this Les Frost Whisper's strength and status in this psychic academy must be very high, if he can kill him alone, the experience he will gain will probably be extremely amazing.

Song Zheng tried to track down Nales Frost, but he didn't dare to get too close.

At the same time, he found himself facing an important problem...... He didn't know how to kill a lich.

If he used the dagger to sneak attack, he didn't even know where the lich was important.

"By the way, it is said that the lich will leave a life box that can control its own life and death, and I don't know where this life box of Les Frost is placed?" Song Zheng thought secretly in his heart.

As long as he got the lifebox of Nalath Frost, maybe the situation could be greatly reversed.

Song Zheng soon followed the angry Les Frost to a room, which was supposed to be where Les Frost usually lived and rested.

However, this is a little different from Kel'thugad's study, which does not see any books, but instead has a large number of instruments and seems to be doing some kind of experiment.

The lich looked at the glass instruments and began to mumble as if to complain about something.

Song Zheng was not interested in his research, but only sneaked around his house to search for it, hoping to find his lifebox.

Since Nales Frost was also in the house, stealing was an extremely exciting act, requiring constant distance and no noise.

However, before Song Zheng could look carefully, there seemed to be some sounds in the distance.

Just as he was wondering, a necromancer had already hurried over.

"Lord Rice, oh no, that elf is here again!"

Les Frost, who was bending down to conduct the test, immediately straightened up, and at the same time, the soul fire in her eyes beat violently.

"Where is she? Immediately let people surround her, and this time she must not be allowed to escape again! ”

"Oops, are they talking about Sylvanas?" Song Zheng listened to it on the side, and his face immediately changed.

There is only one elf who enters this psychic academy, Sylvanas, and there must be no mistake, but I don't know what she did will be discovered by the patrolling undead soldiers.
