"Could it be a teleportation array, but isn't that one-way, are you lying to me? Pen, Fun, Pavilion www.biquge.info" Gray III's expression became very serious.

"No, not really. You Lan hurriedly explained, while raising his index finger, pointing to the ring on it and saying, "It's this ring, this is the standard configuration of every teacher in Yug's wizarding academy, there is a connection array on it, as long as it is activated, it can be connected to Sky City by the teleportation array of Sky City." ”

"Why didn't you tell me that there was such a miraculous thing?" asked Gray III.

Yu Lan explained: "This ring is the same as that mobile phone, and it can be connected to the internal network of the Wizarding Academy, you don't need to know what the network is, only the teacher can get it, and I thought you knew it." ”

"Don't quibble with me, I don't know you don't know yet, if I knew, I would have tried to get it, but since only teachers get it, how did you get it. Gray III could see at a glance that Yulan was quibbling there.

"Well, I'm also a teacher at the Wizarding Academy now, but I haven't officially started classes yet. You Lan said a little shyly, after all, this teacher was obtained by him by begging, everything was just for the convenience of seeing Lilith, and he spent millions of gold coins for this, almost emptying the family.

However, Yu Lan will not say this, otherwise Gray III will despise him again and cannot do without his daughter.

Gray III asked helplessly, "You're not going to sell yourself because of this ring, are you?"

"Of course not, you underestimate me too much, how could I sell myself for a ring. You Lan said proudly.

Gray III breathed a sigh of relief, fortunately Yu Lan was not so stupid, because he sold himself for a ring, although this ring looked very powerful.

"I have Level 3 clearance. You Lan continued.

Gray III asked suspiciously, "What level 3 authority?"

"The entire Sky City is covered with a layer of network, ordinary residents only have the right to use, employees and students have first-level permissions, they can buy things from the academy store, teachers have second-level permissions, they can buy things that can be purchased with first-level permissions at a discount, and they can buy things with second-level permissions, third-level permissions are the director's permissions, you can buy things that can only be purchased with third-level permissions, and you can buy things with first-level and second-level permissions at a discount, each permission can buy things that are one level higher than your own authority at a price ten times higher than your own authority once a month, and each permission has a different number of referrals, and my third-level permission can use the light of the connection three times a month for freeI spent millions of gold coins. ”

When You Lan said the last sentence, he was stunned suddenly, and then regretted it, this sentence should not be said.

Gray III asked with a black line: "In other words, you not only sold yourself for a teacher's ring, but also gave Yug millions of gold coins for a higher level of authority." ”

"It's not millions, it's millions, but there are good things in it, just like now I can still speak very clearly and fluently by your big nose and swollen face, that is, I bought a spell that speaks with my abdomen. You Lan said proudly.

"I'll kill you bastard, you still have the face to say that it is millions, and the empire's taxes for half a year are only a few million, you are too loser. Gray III trembled with anger, although it was You Lan's money, Gray III still felt very distressed.

"Ah...... Ah, don't fight, if you fight again, you'll die, and I didn't spend your money, what are you doing beating me. You Lan screamed miserably.

It's good that You Lan didn't speak, but as soon as he spoke, Gray III became even more angry when he heard it, so he struck harder.

......

"You guys go back first, and Marquis Youlan and I will go to Sky City. "Gray III went outside the door and asked his guards to go back first, because You Lan's ring can only be teleported by one person, and any more will require an enrollment ring, which can bring a large number of people, but You Lan doesn't have that kind of ring on his hand.

In the end, Gray III still let You Lan go, and took back the magic power on You Lan's face, You Lan immediately took out an elixir and crushed it and applied it to his face after Gray III took away the magic power on his face, and the scars on his face immediately disappeared at a speed visible to the naked eye, and in the last few breaths, the scars on You Lan's face disappeared completely.

"You got it from Yogg too, what's your name?" asked Gray III curiously.

You Lan said with a smile: "This is sold in the academy store of the Wizard Academy, you need to use contribution points to buy it, it's called gold sore medicine, it is specialized in treating external injuries, I have the best this, it's called the pill so it can be so powerful, ordinary gold sore medicine is powder." ”

"How much is your gold sore medicine worth?" asked Gray III.

You Lan explained: "I can buy a bottle of the best gold sore medicine at an exchange point, there are a hundred gold sore medicine in one bottle, and the ordinary powdered gold sore medicine can be used many times as long as the wound is not large." ”

"What is that exchange point, and how can I get it?" asked Gray III with some curiosity, although he had heard of the exchange point before, Gray III didn't care, and now listening to You Lan, it seems that it is still quite important.

"The exchange point is a currency used exclusively by the wizarding academy, but it is very precious, if we want to get it, we can only exchange it with genius treasures such as money, in terms of value, one exchange point needs a hundred elemental gems, but one exchange point can only exchange eighty elemental gems, but no one will exchange the exchange point for elemental gems. You Lan explained.

"It seems that Yuge is quite good at business, but isn't this bad for those students from poor families? After all, you said that the exchange points are so important, if I directly exchange the elemental gems for a large number of exchange points, won't I buy all the things in the academy. Gray III said.

"No, there is a limit to this exchange, you can only exchange one hundred exchange points per month, and some things in the academy store are not available for purchase, for example, my golden medicine is available without restrictions. Yulan explained, and showed the goods within his purchase rights to Gray III.

Sure enough, some of the product interfaces are marked with quantity, but others are not marked with quantity, which is what You Lan said about unlimited supply.

Seeing many things in it, Gray III only felt like he was about to move, because some of the things in it were extremely helpful for cultivation, and some of them were also very suitable for the army, and Gray III wanted to find them immediately and get them from him.

Gray III looked at You Lan, You Lan immediately closed the purchase interface, and said: "Don't even think about it, I know what you want to say, but you also know that this is all about the need for exchange points, and you also see that I only have dozens of exchange points now, and it is impossible to buy those military supplies, and it is useless to buy less." ”

Gray III also knew that what Youlan said was true, and even if Yulan's exchange points were squeezed dry, it would only be a drop in the bucket, and there was a possibility that problems could be caused by uneven distribution.

"I know it's impossible, but you'll have to buy thirty exchange points of gold sore medicine, and the powder will do, and I'll give it to my own Praetorian Guard now, as well as the knights who are leading the army. Gray III instantly thought of another use, as for popularizing it in the military land, it depends on the Sky City this time.

You Lan exchanged thirty exchange points for the gold sore medicine with a sad face, and a full three hundred packs of gold sore medicine appeared in the room, which made Gray III startled, it turned out to be a spatial teleportation.

After handing over the golden sore medicine to the guards and bringing them back to the palace, the light flashed, and Yulan and Gray III left the imperial capital.
