The end of the territory of the Northern Icefield is Hokkaido. In order to attack the metal castle, the orc army spent a lot of manpower and material resources.
There are two passages in Huoshen Mountain, one is connected to the underground city, and the other is connected to the metal castle.
Back then, the orc army forcibly broke through the passage connecting the metal castle, entered the underground world, and started a war with the goblins.
In this battle, the goblins finally repelled the invasion of the orcs with their solid castle defense and powerful steel warriors. However, they suffered heavy losses, and more than a hundred of their tribesmen were captured by the orcs.
Since the resources of the Holy Desert Island are scarce, the orcs are not interested here. The biggest purpose of attacking the metal castle is to capture the goblin engineers and design siege weapons and weapons for them.
Otherwise, Mu Bai rescued those goblins last time, and the Minotaur tribe wouldn't be so angry. As a result, their painstakingly prepared century-old plan came to nothing.
After hearing Mu Bai's words, the goblin left in a hurry.
Mu Bai stood in the cell and waited quietly for a while, when he saw a short goblin with sparse hair and a gray beard, holding a cane and slowly walking to the front of the cell, followed by two steel warriors.
Mu Bai glanced at the old goblin and focused all his attention on the two steel warriors behind him.
These two steel warriors each have a ninth-level soul stone inlaid on their chests, emitting a layer of milky white light. They are equipped with a huge prismatic shield in their hands and a giant sword behind them. Their combat power is comparable to that of a saint-level master.
It seems that this old goblin has such a master as his guard, so his identity is definitely not simple.
"Open the door." The old goblin said calmly.
"yes."
An iron warrior behind him immediately stepped forward and pressed a button, and the iron pillar door in front of Mu Bai immediately opened automatically.
"Boy, can you tell me what happened to my people?" the old goblin asked with great concern.
Mubai said lightly: "I only know that one of the goblins is named Tatora. I rescued your tribe from the mine cave controlled by the orcs, and then we broke up. I don't know if they left the north safely afterwards.
