Su Chen initially thought it was the fireball cast by Gianna, but after seeing the dozens of fireballs behind, he immediately became confused.

"It's Master Modra, they're here!" Gianna exclaimed excitedly.

"No...... Wrong direction, these fireballs are coming from the north. Su Chen shook his head lightly and looked at the source of the fireball extremely cautiously.

Gianna couldn't help but be stunned when she heard this, the north of Alterac is Lordaeron, where there are only undead now!

Still, the fireballs from the hillside continued one after another, mixed with ice arrows, and even shadow arrows in dark magic.

The Crypt Lord was obviously furious after receiving a large amount of magic attack suddenly, and the carapace behind it trembled rapidly, even revealing wings like cicada wings, emitting an extremely piercing insect chirp.

The next moment, a large number of beetles that looked like miniature versions of the Crypt Lord immediately emerged from the ground, rushing like a tide to think of the source of those magic.

But there was more magic pouring down the hillside, and although it was low-level magic, it was a lot of it.

At the same time, a row of shields appeared on the hillside to ward off the onslaught of the beetles, and behind the shields was a group of warriors, a group of ragged undead warriors.

"It's a scourge of the dead! No, how could they be fighting that big bug? Gianna's eyes were confused.

"Don't worry about it yet, let's take the opportunity to kill this big bug first." Su Chen frowned, the holy light on his body flashed, he had already healed the damage caused by those flying insects and damage rebound to himself, and immediately rushed towards the Crypt Lord who was a little overwhelmed by the attack of a large amount of magic.

Gianna hurriedly began to chant the magic spell.

However, before Su Chen could get closer, the Crypt Lord's pair of hideous front claws had already stabbed heavily into the ground, and the huge crack spread rapidly in all directions again, and countless thorns stabbed out like a forest of spears.

Both Su Chen and Gianna had to dodge.

When the crack on the surface stopped spreading, Su Chen was about to speed up to attack, only to find that the huge Crypt Lord had actually begun to burrow into the ground, and the speed at which he had escaped into the ground was very amazing.

Su Chen didn't stop it, he didn't think he could fight this crypt lord underground.

What's more, the effect of cutting off the spider silk before before had already been revealed at this moment...... When the Crypt Lord burrowed into the ground, the treasure chamber fell off his back!

Now that the Book of Medivan has been captured, the purpose of this trip has been achieved, there is no need to fight the Crypt Lord again, and at this moment, there is an army of undead of unknown origin on the northern slopes.

The Cave Lord's massive figure was completely submerged underground, and the spiders and small beetles around it had disappeared cleanly.

However, Su Chen and Gianna were still in a fighting state, because the undead army had already rushed down from the hillside, numbering in the thousands, and there were more than a hundred necromancers among them.

"So many undead ......" Gianna leaned close to Su Chen's side a little nervously, the battle just now had consumed a lot of her mana, and it was difficult to continue fighting.

"It's okay, I'll deal with these undead." Su Chen gently held her hand and comforted her, he was not very afraid of these oncoming undead, because there didn't seem to be any strong ones in this group of undead, and he could completely use the power of Frost Grief to control it.

Necromancers with ranged attacks would have been a nuisance, but surprisingly, when the Crypt Lord left the ground, the necromancers never released their magic.

The undead were so close that even though the wind and snow had not stopped, they could still see the details of the rotting on the zombies.

For some reason, Su Chen suddenly felt some familiar feelings in his heart.

The undead who came in like a tidal wave suddenly stopped, like statues standing in the wind and snow.

A tall necromancer walked over with a staff that was already somewhat rotten, and before Su Chen could react, he suddenly fell to his knees.

"I've seen His Royal Highness the Prince." The necromancer's voice was hoarse.

"Are you...... People from the Barov family? Su Chen finally recognized the Barov family's emblem from his decaying mage robes.

"Yes, I am Victorus, and we are His Highness's most faithful servants."

"How did you end up here, the rest of the Barov family?" Su Chen hurriedly asked, he never expected to meet someone from the Barov family on the Alterac Mountains.

"They're right in front, and the master and the lady have set up a base here."

"Oh......" Su Chen finally breathed a sigh of relief, it seemed that the Barov family did not stay in Keldaron, but moved into the Alterac Mountains.

"You ...... They...... What's going on? Gianna looked at the changes in front of her with some consternation.

"They are members of the Barov family, and they have been transformed into undead by the Lich King, but I used this sword to free them from the Lich King's control when I passed through Keldaron, just like those spiders just now." Su Chen hurriedly explained to her.

"People from the Barov family......" Gianna nodded slightly, and the fingers that had been clenching the staff finally let go a little, but her eyes were still full of wariness.

After all, there is a group of undead in front of you!

Su Chen didn't care about this, as long as the frost sorrow was in his hands, the souls of these undead were under his control, and he was absolutely loyal, but he was not good at telling Gianna this information.

After all, in essence, he has the same status among these undead as the Lich King!

Su Chen quickly began to step forward to look at the treasure chamber left by the Crypt Lord, the Book of Medivan was the thing he valued the most at the moment.

Several undead warriors immediately stepped forward to help clean up the spider silk that was tangled around the vault.

After cleaning it up, Su Chen found that this treasure chamber was engraved with runes, and when it was attacked, a powerful magic enchantment would immediately appear, even the sorrow of frost would be blocked.

Obviously, the mages of Dalaran did value the Book of Medivan and set up an extremely powerful defensive barrier for it, but those mages were too rigid to consider that someone would steal the entire chamber.

Of course, apart from the undead scourge of the Crypt Spider Clan, no one else can afford to infiltrate Violet Castle to steal the Chamber of Secrets.

"No wonder the crypt lord can only run around on his back......" Su Chen saw that he couldn't destroy the defensive barrier for a while, so he had to put away the frost grief and give up the idea of opening the secret room here.
