Su Chen didn't like the underground environment, even if he had a smart brain to provide a surrounding vision, which was almost the same as what he had seen in person, but the cold environment still made him a little uncomfortable.

After all, he is still the prince of Lordaeron, not the Lich King, and he still yearns for the sunny ground.

"Your Highness, you don't have to worry, I am very familiar with the underground of Northrend, and I will soon find a new exit, even if there is no exit here, it will not take long to dig a new one." Abic said.

Su Chen couldn't help but smile, now he can only believe in this guy, and at the same time, he can't help but feel sorry for the lost roots of the World Tree behind him, and now those roots are only afraid that they have long been possessed by those faceless ones.

However, through this battle, he also fully understood the combat power of those faceless ones, although those guys are very good in attack and defense, but what they are best at is the same mental control ability as Yugsaron.

Mind control is very deadly for ordinary armies, but it is useless for Su Chen, and there are also undead who are not afraid of these spirit attack abilities!

If you need to fight these Faceless Ones in the future, it is best to use an undead type army.

"It seems that if you want to deal with Yugsaron, you still need to defeat Naozu first, as long as you can master the army of the undead, you may have the capital to start a war with Yugsaron......" Su Chen walked in the darkness while secretly thinking about his future plans.

Abic was very familiar with the underworld, and soon found a new exit, but this exit had obviously not been used for a long time, and it was even occupied by a few bears, and it was full of fishy smell.

Su Chen originally thought that he should have come to the north of the Grizzly Bear Hill, perhaps close to the territory of those bear monsters, but when he came out of the cave with Abik, he couldn't help but be stunned.

In front of him, he didn't see the verdant forests of Grizzly Hills, but a stone building with a very unique style.

"I'm afraid this is already the territory of the trolls...... "Abik's spider's head turned around.

"We're indeed on the troll's territory, look over there...... That huge building. Su Chen had already recognized that these buildings all had a distinctly troll style.

In the distance, the huge building looked like a huge city towering over a dangerous pass, so tall that it was taller than the peaks on either side.

"That's Daxaron Fortress! We should already be in Zudak. Abic looked south, but he recognized the huge building.

"Daxalon Fortress......" Su Chen was shocked, he naturally knew that this was a fortress established by the Zudak trolls on the southern border, but he didn't expect this Daxalon Fortress to be so huge, almost like a huge city.

"It seems that I still underestimated these trolls...... I don't know how powerful these trolls who almost dominated the entire Azeroth were at the beginning......" Su Chen sighed in his heart, just the Daxalon Fortress in the distance estimated that it would be difficult for humans to build it at present.

"Your Highness, don't worry, although that fortress is huge, we can completely bypass it." Abic said quickly.

"Really...... If they could go around, why would those trolls build such a huge fortress? It doesn't seem to be a defense at all. Su Chen asked with some confusion.

"No one knows, maybe it's for the sake of beauty, those trolls have always liked to build some tall pyramids to show off or worship their gods, this Daxsalon fortress is probably just to show off their strength, I will find a way for His Highness to go south, even if there is no safe road for a while, we can pass through the underground again." There was a hint of sarcasm in Abic's voice, and it was clear that even he, a native of Northrend, didn't know what the Dhakale trolls were thinking.

"Don't be in such a hurry, since we're already here, let's take a look at the situation inside this Zudak." Su Chen thought of Illidan who had already entered Zudak, and his heart couldn't help but move.

Since Illidan was attracted by the secrets of these Dakale trolls, it would be nice to know about it by the way, and it would be great if he could meet Illidan and ride Princess Hahoran back to the base in the southern part of Grizzly Hills.

Abic did not object to this, presumably having been reluctant to return south after the battle with the Faceless Ones.

Su Chen originally thought that this Zudak should be full of trolls, but he soon discovered that most of the area here was actually dense forest, somewhat similar to the Grizzly Bear Hills, except that the trolls had built a large number of stone stairs and altars based on the surrounding hilly terrain, so that the whole Zudak looked full of troll style.

The two of them had walked a short distance through the dense forest of Zudak, and soon they heard a strange sound.

"There seems to be a battle ahead?" Su Chen's brows jumped, he quickly judged that it was the sound of a battle after a long time on the battlefield, and at the same time, he had already quietly let Zhi Brain expand the detection range.

"It's true that there are people fighting, and it's a big battle for a lot of people." Abic said in a deep voice, perhaps because they have lived underground for a long time, these spider demons do not have good eyesight, but their hearing is excellent.

Su Chen couldn't help but have some doubts in his heart, he was now in the hinterland of Zudak, even if Illidan came here, he should have used sneak attacks, and it was impossible to openly fight with a group of trolls, otherwise once he attracted the gods of the trolls, it would be very difficult even if he wanted to escape.

However, the two soon saw the specific situation of the battlefield, but to Su Chen's surprise, in addition to a large number of trolls, the other side of the battle turned out to be undead!

"The Scourge's Legion is really attacking Zudak!" Su Chen felt a burst of surprise in his heart.

The path of the undead scourge to expand south into the Dragonbone Wilderness is blocked by the presence of dragons, and the Soracha Basin to the west of it is also protected by the Titan Guardians, who cannot be rivaled by the Titan Guardians with the strength of the Undead Scourge.

To the east, the Storm Mountains where the Titan City of Ulduar is located are unreachable, and only by heading east into Zudak through the Crystal Song Forest can they expand beyond the Icecrown.

In the history of Warcraft, Arthas, who became the Lich King, also followed the same expansion route and had already taken the fortress of Daxalon, but unfortunately the Northern Expedition did not give him time to control all of Züdak. (To be continued.) )
