Dorick said: "The dwarves and goblins have been living in the Vulcan Mountain for generations. Behind the underground city, passing through the mineral vein area, is the metal castle of the goblins. It is easy to get there, but this mission has certain dangers.
You may be attacked by goblins, depending on what benefits you can bring to them. If the reward is generous, there should be goblin engineers who agree to your request."
Mu Bai thought about it for a while, then nodded in agreement and said, "Give me a map and I'll be ready to send it out right away."
As soon as Dodrick heard Mu Bai agreed, he immediately happily ran to the blacksmith's room to draw a map for Mu Bai.
Tianming on the side asked: "Do you want me to accompany you?"
Mu Bai smiled and shook his head: "Let me try it myself. It can be regarded as a kind of experience for me."
Tianming said: "Okay then, be careful yourself."
The two of them stood outside the blacksmith's room and waited for a while, then saw Dodrick walking out with a freshly drawn map in his hand.
He handed the map to Mu Bai and said, "The Metal Castle is about three thousand miles away from the underground city. With your strength, if you travel at full speed, you can get there in about three days."
Mu Bai glanced at the ground twice, remembered the map in his heart, and put the map into the space ring.
"I'll get ready and leave right away," Mu Bai said.
Dodrick smiled and said: "Let's go, let's go have a few drinks first, and we won't be in a hurry."
…
That afternoon, Mu Bai simply prepared some food, took the dragon-slaying sword with him, and set off on his way to the metal castle alone.
After coming out of the back city of the dungeon, Mu Bai cast an advanced flying technique on himself and rushed to the metal castle at full speed.
The area spanning three thousand miles between the underground city and the metal castle is a large mining area. The ore resources here are very rich, much more than those on the mainland, and various types of ores are found here.
After several wars between the two tribes in history, the ore area has been divided between the two sides, each occupying an area of 1,500 miles. There is basically no dispute.
Mubai couldn't tell the difference between day and night. After his strength improved, his flying speed was obviously several times faster than before. It only took him less than two days to enter the outer mining area of the metal castle.
