Annu said to the white steel "Mopu": "There are two types of portals: small and large. Small portals generally only allow a few people to pass through, and the spatial cracks will heal quickly after tearing and cannot be maintained, and the energy required to tear the space is relatively small, the construction materials used are relatively cheap, and there is no need to stabilize the door. Each Mage Tower is available for construction, and can be built by nobles and chambers of commerce with a little money. It just so happened that I had set up a few small portals with my teacher when I was an apprentice, so I was familiar with them.

If the tear space is large enough, then the space crack will not heal, but will automatically form a kind of spatial crack with a stable valence, which can continue to exist even if no energy is injected, but there will be some fluctuations from time to time, of course, these fluctuations can be overcome with the stability gate.

This large portal can be built taller than a tower and wider than a city gate, enough to easily pass through large armies, and is a slightly advanced permanent portal. Although I have not presided over the construction of the large portal, the construction of the large portal is a big project, almost half of the mages in our Red Tower have participated, and I am one of them, and my work has even been analyzed in detail by Teacher Adam as a case study during class. ”

General White Steel asked suspiciously, "Then if I'm willing to pay you enough Mithril, can you help me build a portal?" ”

Annu rolled her eyes: "I know very well how to cultivate, but I can't cultivate, not only me, in fact, any magician in the Seven Kingdoms is the same, even the legendary ones are no exception." ”

"Why is that?"

"Because there's no material!" Annu spread her hands, "Small portals don't matter, as long as you are willing to spend money, you can always find enough materials." But large portals are different, not only do they require a lot of hardened Mithril, but they also require some special materials. ”

"Special materials?"

"That's right, like the trunk of the Tree of Life, the keel, the giant ice spirit, or the very large granite.

When the spatial crack fluctuates, there will be a very huge tearing force, and if the main material is not strong enough, it will be torn and shattered, but copper and iron, which are demonic metals, cannot be used, otherwise it will interfere with the operation of the magic array on the portal. ”

Bai Gang thought about it, there are many materials that are strong enough, but he doesn't know which ones can be used and which ones can't, if he wants to judge, the best option is to bring Annu to the base and let him try all the suitable materials on the earth.

"What if I have the materials?"

Anu was surprised: "You actually have this material!?" ”

"I guess I have some clues."

Hearing Bai Gang's affirmative answer, Annu finally became serious: "But even so, it's still useless to rely on me alone." With enough materials and workers, I can build a portal, but it takes a lot of energy to tear through space, and it's impossible to do it without more than three legendary mages joining forces! ”

Bai Gang shrugged, not to mention the three legends, he would be able to come up with a mage who didn't know the level now, well, it was himself...... But the dimensional rift at the Storm Base is there and there is no need to tear it at all, so the three legendary mages can be saved.

So he lied again: "With the prestige and financial resources of our Bai family, it is not a problem to invite more than three legendary-level figures, but they are not magicians, and I don't know if they can do it." Well...... I really have no choice but to throw money at it, and if I can pay enough Mithril, I guess I can find a legendary mage to help, right? If they don't like Mithril, it doesn't matter, there are so many good things on my side, there's always something they like. ”

Anu opened his mouth, but he didn't know what to say, he originally thought that Bai Gang was just a rich nobleman, but now it seems that he is definitely far underestimated!

You know, which of the large portals of the Seven Kingdoms could not be built by accumulating tens or even hundreds of years with the strength of the whole country!? And it is not a problem to say that it is not a problem to invite more than three legends!? This kind of strength is not worse than that of the king of a country!

As for spending money please!? And that's so understatement......

Anu always wondered if the guy in front of him had found the legendary Endless Treasure Trove...... Sure enough, this White Earl's greatest talent is to be rich!

Seeing that Annu was silent, Bai Gang simply proposed:

"Monte Cristo has a debt that must be paid. Since everyone has helped me, then according to the tradition of the Bai family, I must repay your kindness. I don't know if you're in a hurry to go back to the Seven Kingdoms, but if you're not in a hurry, how about returning to the fleet's temporary berth with me, where I can entertain you well! ”

Dilitian thought for a moment and said, "I don't have anything special, if you have a surplus of spirits there, I want to buy some, this wine can save lives in the ice and snow, so I'm going to go, what about you?" ”

The dwarven hot stove grinned and asked, "White Earl, do you really have wine there!?" It's the kind we drank before. ”

"Of course there is, and there are many better than that!"

The dwarf's beard was cocked in excitement: "What you said is true!?" That's great! As long as I have a breath left, I will definitely go! ”

Sawyer opened his mouth, but in the end he didn't say anything, and twisted his face to the side with a "hum" as a tacit approval, he didn't like Bai Gang, but food and wine were his favorite.

Others also said that they didn't have any particularly urgent matters to deal with, and they could go to Baigang for a while.

Seeing that no one spoke again, Dilitan smiled and said, "Okay, since everyone has no opinion, let's go to the White Earl's camp to rest first." ”

…………………………

Just two days after the knights and the expedition team each set out on their own way home, by the river where they met, a strange team of cavalry slowly emerged from the woods, they rode skeletal horses and wore black robes, their whole bodies were wrapped in tattered black robes, and they could not see their bodies at all, and they could only roughly see that these knights were very burly.

One of the black-robed knights walked up to the sword marks left by Ivy, turned over and dismounted, stretched out his thin fingers and pinched some of the dried blood stains left on the ground by the sword qi of the white steel and put them into his mouth to taste them carefully, and then suddenly turned his head to look in the direction where Bai Gang had left, and let out a long roar with his long mouth.

At this time, you can vaguely see that under the tattered black robe is a terrifying face with no skin, only dark cyan carrion wriggling!

The black-robed monster turned on his horse and chased after them with his companions in the direction they had left.
