After re-entering the stealth state, Song Zheng walked away from the battlefield without looking back.

Now he only has the ability to strike a blow, and he must retreat regardless of whether he succeeds or not, otherwise those necromancers can use a wide range of attack magic to force him out after they find out that he is sneaking.

Of course, the more important point is that after using the Killing Feast and the Shadow Cloak continuously, his physical strength has been depleted, and even his head feels a little dizzy, if it weren't for the recent upgrade, his own strength attribute has also been improved, maybe he would faint on the spot due to excessive weakness.

When hiding in a no-man's corner, Song Zheng hurriedly stuffed a piece of candy that had already been prepared into his mouth, but it was of no use to the hunger that rolled up like a tide, so he could only keep stuffing food into his mouth.

"Do you have to eat while fighting in the future......" Song Zheng was a little depressed in his heart, this physical exertion too fast was always a problem, unless he could find a new energy supply, or further improve his physical strength.

However, he also knew that the reason for this depressing problem was mainly because he had randomly obtained a powerful skill such as 'Killing Feast', which should have been learned at a very high level, and his physical strength should be enough to support the use of this skill many times.

And now he forcibly uses the 'Killing Feast' under low-level conditions, and the result is that his physical strength is not available.

After eating a pile of food in a hurry, the terrible hunger was finally relieved, and the mind no longer felt dizzy.

Song Zheng immediately began to check his attribute panel, but to his disappointment, he didn't gain any new experience - the dean Gading didn't die after being attacked by him.

"That guy's defense is so high? It's not even like this......" Song Zheng pouted.

However, if he was hit by his own set of killing feasts without opening the magic shield, and was bombarded by two fireballs at close range, Nagading would be seriously injured even if he didn't die.

"It's a pity that there are no good weapons, if the hammer of destruction is still in hand, that move just now can definitely kill Gardin." Song Zheng sighed secretly.

Although the dagger in his hand was also a mythril dagger with magic that he bought at a high price, it couldn't compare with those artifacts after all, and its destructive power was not even as good as the knight's sword in Catherine's hand.

"Let's hope Sylvanas can take the opportunity to break through." Song Zheng thought about it and decided to quietly return to see the situation.

However, when he arrived at the original battlefield location, he found that there were only corpses all over the ground, but there was no trace of Sylvanas.

"Gardin and Les Frost are not here either...... Song Zheng soon found that the corpses on the ground were all those necromancers and a small number of skeletons and ghouls, all of whom should have been killed by Sylvanas.

There are also many traces of battle in one passage, and it seems that the battlefield has only shifted.

Song Zheng immediately followed the traces of the battle, and on the road he could see the corpses of many undead, some of them were killed by arrows, and some of them were directly cut into two pieces...... It was supposed that Sylvanas had used the dagger he had with him.

"It looks like the fighting is still raging." Song Zheng was a little worried in his heart, so he could only ignore the stench of those undead corpses, and eat something to replenish his strength while chasing, so as to face the battle he might encounter next.

The underground psychic academy was very large, and the various corridors were intricate, like a maze, and Song Zheng soon found that he could not find the way back after tracking.

"I don't know which direction I fled, I hope she'll be fine." Song Zheng was very worried about Sylvanas's safety.

You must know that Sylvanas came to the Human Kingdom to help because of his trip to Silvermoon City, and if he encounters danger because of this, then he will definitely feel guilty for the rest of his life.

Song Zheng didn't know how long he had been walking underground, just following the traces of the battle, and suddenly he felt his surroundings become brighter.

"Here it is...... Surface? Song Zheng looked around in astonishment, only to see that the moon in the sky could already be seen through the window on the wall...... He's out of the dark underground!

"This should be the Manor of the Barov family on the ground, and it seems that there is more than one exit from the Psychic Academy." Song Zheng quickly determined his position, and at the same time, he breathed a sigh of relief in his heart.

Now that the traces of the battle have come to the surface, Sylvanas has a much better chance of escaping.

The Barov family's manor house is very beautifully built, and after the undead disaster occupied this place, it did not do too much damage to the buildings on the ground, and at this moment, those halls and rooms still maintain their original furnishings, and many of the furniture are inlaid with gold, silver and precious stones, so that Song Zheng's thief's heart can't help but be a little moved.

But the corpses on the ground soon reminded him of the danger he was facing.

After walking through the manor for a while, Song Zheng finally heard the sound of a fierce fight in front of him, mixed with the crackling sound of magic, and it seemed that he had finally caught up with Sylvanas and the necromancers.

He immediately approached cautiously, ready to help Sylvanas again.

However, when he saw the battle, he couldn't help but be dumbfounded.

There are currently more than a dozen necromancers participating in the battle, and the lich Les Frost is also there, but it is Sylvanas who has the upper hand at the moment...... She's chasing down Les Frostwhisper, occasionally killing the necromancer who stands in her way.

"Stop, elf, there should be no hatred between us, we are willing to let you go, and we are willing to compensate you for whatever you need." The Lich Leth Frostwhisper's voice was hoarse and fast, two arrows were already stuck in his body, and one of his left arms had long since been broken, and he looked very embarrassed, trying to make peace with Sylvanas.

"You've just killed one of my most important friends, and what I need is the lives of all of you to honor him." Sylvanas's voice was filled with a great chill, and the longbow in his hand was flicked continuously, and multiple arrows were shot in an instant.

The lich Les Frostwhisper finally couldn't resist it, and after being shot by several long arrows at the same time, almost all of his bones exploded, and he became a pile of broken bones on the spot.

The rest of the necromancers tried to escape, but were quickly shot by Sylvanas one by one.

"Little Chef...... These undead have been slain, and I have finally avenged you. Sylvanas's voice was filled with deep melancholy and sadness, and her face was very pale, and she sat down in the pile of corpses directly after the battle, obviously her previous battle had caused her great physical exertion, and she was almost holding on to the fight.

"She doesn't think I've been killed, is she?" Song Zheng, who was hiding on the side, couldn't help but jump wildly out of the corners of his eyes, it seemed that he had been mistaken about one thing, it was not those undead who were chasing Sylvanas before, but she was chasing these undead, and even chased them to the ground!

"What a tough woman, but she forgot to make up for Nalais Frost just now......" Thinking of this, Song Zheng was suddenly full of remorse. 10
