A month passed in the blink of an eye.

Since he became a lecturer in the college, Lin Fei doesn't have to worry about anything else. As long as he passes the examination every time, he has more free time.

Lin Fei doesn't need to go to the array department often. He only needs to go several times a month. The rest is for them to learn and understand by themselves.

Lin Fei has never been a lecturer, but there is a system. After a little research, there will be a course immediately. After going there for two or three times, those arrogant Tianjiao are convinced. Lin Fei stands firm and throws out new array routines appropriately. Tianjiao worships him collectively and wishes to study here every day.

In addition, in a month, Lin Fei also did some things, such as cashing out the treasures of the demon clan and completing a deal. The only thing that upset Lin Fei was that the alternate saint of the demon clan of Qin LAN came to the emperor peak from time to time to learn from each other. In Lin Fei's opinion, it's a pretty trick on himself.

The water of demon God empire is very deep. It's OK for Lin Fei to play and trade with them. If we really want to go deep, we will be doomed. Therefore, we don't have any interest in the beauty scheme, so it will be troublesome to eat it.

Unfortunately, refused several times, Qin LAN is still straight to the college, there are all kinds of rumors in the college, so Lin Fei is speechless.

Goblins are goblins. They're always busy.

Lin Fei simply opened the array ban. Except for those who hold the token, no one can enter. This calms Lin Fei's ears. This also leads to Qin Lan's white eyes and deep resentment towards him. In the eyes of outsiders, he seems to be a ruthless person. He bullies Qin LAN and makes Lin Fei gnash his teeth.

"It's been a month, and it's time to go out for a walk."

Since the last time he made a lot of money from the fifth Prince and vice president, Lin Fei has become a rich man. Few people of the same age have this wealth.

Before Lin flies out, someone comes to the door first. It turns out to be Qin LAN.

"Lin Shao, you've come out at last. Don't you like little girls so much?" Qin LAN looked at Lin Fei with a sad face, "can't even let a little girl go in and sit down?"

Since the completion of the transaction, Qin Lan's position in the demon Empire has been greatly improved, especially the demon treasure returned from the trade, which greatly increases the strength of a demon clan strongman.

According to the discussion and discussion of the high-level of the demon God Empire, Lin Fei should still have the demon treasure in his hand. He told Qin LAN to keep the relationship with Lin Fei, and it was better to capture each other's secrets by using the beauty trick.

So, there was the scene before.

Especially when Lin feizhan showed his strong control of the array, Qin Lan was more concerned about the other side and came to Emperor peak from time to time.

Today's Qin LAN is dressed in black palace clothes. Her figure is graceful and graceful, which makes a man feel impulsive. Especially now, she has a sad expression. It is hard to resist.

Lin Fei said with a wry smile, "sister Qin LAN, I've been studying arrays these days. You know that. It is necessary to keep quiet when studying the array. You should understand it! "

Qin LAN knew that Lin Fei was a cunning guy. Several of his ten sentences were false. However, Qin LAN couldn't offend the other party. What if there was a demon treasure in his hand? What's more, the master reminded himself that if you want to sit in the position of Saint, you can't start from Lin Fei. Maybe you have a chance to defeat some other alternate saints.

"Yes, my sister understands very well!" Qin Lan's expression changed, showing a sweet smile, "look at the younger brother's appearance is ready to go out for a walk?"

Lin Fei said with a smile, "a new array has been developed recently. I intend to take it to the chamber of Commerce for auction and see the market."

"You want to sell the flag?" Qin LAN has a plan.

"How to say, there are still some differences between my device and the array flag. In my personal understanding, it is called array scroll, inner seal array!"

This is Lin Fei's latest research.

In order to be unique in the expeditionary Empire, Lin Fei felt that he should show himself, so he made the array scroll. Anyway, it didn't need many energy units. However, it was not a problem to describe him as a unique existence among array mages.

The array scrolls are not absent from the expeditionary empire. They are not very powerful. At the same time, there are various defects. As time goes by, people ignore them. Lin Fei completes the reform of array scrolls with a little research.

"You have worked out the array scroll!" Qin LAN covered his mouth with an incredible expression.

"Can't you?"

Qin LAN has heard of the array scrolls. Someone from Imperial College has studied it. He wants to simplify it and become an auxiliary in future battles. However, it has not been successful.

Qin Lan was really shocked when he heard that Lin Fei's research was successful. If this technology covered the Empire in an all-round way, it would be a great blow to the demon God empire. As we all know, it is not easy to master the array. Therefore, the status and strength of array mage need not be questioned.

"Lin Shao, I don't know if you are qualified. Take a look at your array scroll. For a long time, my sister has been longing for it, but she hasn't been able to do it!" Qin LAN a face of curiosity said."The goblin is doing this again!" It's not the first time that Lin Fei has seen Qin LAN show this kind of expression. However, it has to be admitted that every move of the demon clan is quite tasteful. It is no wonder that in history, so many powerful people of the clan have been confused by the demon clan. It can be seen from Qin LAN.

"Here you are. See for yourself!" Lin Fei takes out an array scroll and throws it to Qin LAN.

Yes, just throw it to Qin LAN.

Lin Fei has made a lot of these array scrolls.

"It's really the scroll of the array!" Qin Lan was very surprised when Lin Fei became easy to discuss. When the light scroll reached his hand, he immediately felt the extraordinary of the scroll. With his powerful divine sense energy, he could sense the horror contained in the scroll. This scroll alone can cause certain damage to the strong one or two turns.

"Your array scroll is auxiliary. After opening, there will be a trapped array, which can trap the second turn professional strong man!" Lin Fei explained.

Although the array scroll can only trap one or two occupation changes, it has no effect on three rotation occupation, but it has a different meaning in Qin Lan's opinion. If the array scroll is upgraded, the strong people in seven or eight turn occupation should be cautious. If one is careless, if it is not handled properly, it will lose the whole game.

"Go!"

After asking how to use it, Qin LAN lightly drinks, and the array scroll is opened.

A bird just flew by. The scroll of the array was unfolded, and the bird seemed to hit a wall. Come and go to toss more than ten times, always can not get rid of the body, see Qin LAN secretly shocked.

"Lin Fei's younger brother is really a smart man. He has developed the array scroll!"

Waiting for Qin LAN to speak, a voice from afar came.
