The battle around him was still going on, and Su Chen was still disguised as a wounded death knight, curled up in the corner and watched the undead guards coming and going in the distance.

Those spiders are not stupid, after the sneak attack has been effective, they have become more and more courageous, and they have taken the essence of this guerrilla warfare to the extreme, burrowing everywhere to sneak attack those patrolling undead troops, causing the undead who had already controlled this underground kingdom to shrink their defense line and take the initiative to abandon a large area.

After dodging for a while, Su Chen's physical strength had already recovered somewhat, and this time the plan to seize Tyr's hand was so smooth that he himself was a little surprised.

However, after reacting, the undead scourge has begun to frantically search the surrounding crypts.

Su Chen even felt a huge spiritual force sweeping over here, but fortunately, Zhi Brain reacted in time, and only then managed to disguise himself as an ordinary undead to deceive him.

"This should be Nao Zu personally scanning and searching, it seems that even Nao Zu also attaches great importance to this Tyr's arm...... Su Chen secretly thought, although the undead calamity is powerful, he should not dare to fight Ulduar's idea yet, and he can only make up his mind on these peripheral Titans.

However, although he had deceived the ordinary undead soldiers in disguise, he still did not dare to go out through the entrance, which was undoubtedly the most heavily guarded now, and there were a large number of shadows patrolling that could detect stealth and stealth.

It is estimated that there are also a large number of undead armies on the surface, and it is likely that Neozu already knows that he has come to Northrend, and once his traces are discovered, it is estimated that the Scourge will desperately come to hunt him down.

Su Chen was going to continue to find a corner to hide, and wait until his strength had almost recovered before making the next move.

However, to his surprise, the spider named Abic found him!

"Could it be that these spiders have any special tracking ability?" Su Chen secretly thought in his heart, it was definitely not an accident that these spiders could still find themselves who were deliberately hiding in the melee.

"Thank you for your advice. We've managed to destroy a large number of undead and reclaim a lot of them......" Abik looked very enthusiastic, unaware that Su Chen had taken advantage of their battle to capture Tyr's hand.

This made Su Chen feel a little sorry in his heart, although the two sides took what they needed, he still used these spiders after all.

"You're welcome, right...... Do you know that there are other exits around here? I need to return to the Temple of Dragon's Sleep immediately to lead a large army to exterminate these undead. Su Chen's heart suddenly moved. Immediately asked.

At present, going out from the original entrance is tantamount to throwing yourself into a net, but there will definitely not be only one exit from a huge underground kingdom.

"An exit nearby? No. Abic immediately shook his head and said, "We never thought of going to the ground, so we rarely took the initiative to dig out. ”

Su Chen couldn't help but be speechless for a moment, it seemed that he had to dig an exit by himself, but now he was thousands of meters deep underground, and it was not easy to dig an exit, not to mention that there were a large number of undead troops around, and it was easy to expose himself once he excavated.

"But we have an exit to the southwest, if you wish. I can take you there, but it's a bit far, and you'll have to go through a long underground passage. Abic suddenly said again.

Su Chen couldn't help but hesitate a little when he heard this, the southwest exit that Abik said was probably the cave he knew was located in the woodland in the west of the Dragon Sleep Temple, if he calculated carefully, the distance from the tomb of Galakron to the underground kingdom of Eldraine-Nirub was not close, almost spanning most of the dragon bone wilderness, and this was still the straight-line distance of the ground. If you go underground, it is estimated that the distance will be even farther.

However, considering that the Undead Scourge is now conducting a frantic search, Nao Zu has been scanning this place on a large scale from time to time. If you're not careful, you'll be exposed, and it will take some time for you to completely get out of your weakened state, so it's better to follow these spiders deep into the ground, so that you can have enough time to recover.

More importantly, he himself is interested in the underground world of Northrend.

"Well, there are more and more undead disasters here, and you must avoid them." Su Chen finally nodded in agreement.

"Hmm. We have achieved unprecedented results this time, and I am preparing to seek out our prophet Exeter to spread this tactic. Abic said.

With these spiders leading the way, it was almost unimpeded in this underground world, and Su Chen was able to ride a spider once.

Because those spiders crawl too fast underground. Su Chen only felt dizzy, only Zhi Brain was still silently recording the routes he passed on the way along the way, and drawing a map of the underground kingdom that was constantly improving.

A day later, Su Chen felt that he had gone extremely deep into the underground of Northrend, but the surroundings were becoming more and more beautiful, there were a large number of underground caves where these spiders passed, and there were many underground plants that could emit various fluorescences, among which most of them were mushrooms, which dressed the entire underground world in a strange way.

However, to Su Chen's surprise, there were many very strange-colored stones underground, which seemed to be able to emit blue-green fluorescence.

"Why do these ores feel a little evil......" Looking at those ores that seemed to be very beautiful, Su Chen felt a little uneasy in his heart.

"These stones are tainted with the scent of that creature, and have very special powers, which are perfect for crafting weapons and armor, but we generally don't dare to use them." Abic explained.

"Could it be that these are the Saron Evil Iron Ore?" Su Chen was secretly surprised in his heart.

In the history of Warcraft, the rise of the Lich King is largely related to the Saron Evil Iron Ore, not only are most of the equipment of those undead armies made of Saron Evil Iron, but even its Icecrown Fortress is forged from Saron Evil Iron, if there is not enough Saron Evil Iron, even if the Undead Scourge expands a large number of troops, it is simply unable to arm these troops.

However, in the history of Warcraft, the alliances and tribes of the Northern Expedition also mined the Saron Evil Iron in large quantities, and used it to forge new weapons and equipment, and finally attacked the Ice Throne, so it can be said that the success of the Undead Scourge was due to the Evil Iron of Salon, and its failure was also due to the Evil Iron of Salon.
