Inside the laboratory.

Tessa circled around the teleportation circle a few times, tilted her head and asked, "Is this the same as the one you set up in the Mage Tower?" ”

"The basic module and the underlying logic are the same, but the direction and iteration method are very different, the connection between the teleportation arrays is not a simple two-way rule, senior sister, you know, iteration is not only overlapping, but also an alternation, but the way of alternation determines the ...... between several teleportation arrays"

Colin talked for a long time, and found that Senior Sister had no response, so he stopped and waited for a while, and asked, "Senior Sister, do you understand?" ”

"What do you say?" Tessa asked rhetorically.

"It's actually quite simple." Colin smiled: "It means that every time you add a circle to the teleportation chain, the complexity of the new circle will be greatly increased, and the difficulty of teleporting spells will become more and more difficult." ”

"Oh, I see." Tessa seemed to have a sudden realization.

"Senior sister, why don't I teach you? So that we can go back to see the teacher together. ”

The teacher doesn't learn because he is too powerful and is afraid of backlash, but the senior sister is ...... It's barely a mid-level.,I don't usually like to study.,I shouldn't be able to form any powerful magic concepts.。

In the past, I didn't tell Tessa about the space magic because I was worried that my senior sister would worry about it, but now that I have succeeded, I no longer have any worries about this.

"Is it easy to learn?" Although Tessa has no ambitions, the practicality of space magic also makes her a little excited.

"Simple."

After Colin finished speaking, he began to explain in high spirits.

……

Ten minutes later.

"I think it's good to ride in a carriage and see the scenery." Tessa yawned and tactfully interrupted Colin.

Colin: "......"

Tessa awkwardly changed the subject: "So, you have also used it to travel back and forth between Fortress and Brighton for the past six months?" ”

"Duke Oliver has an apartment in Victor where Sophia used to study abroad, and I installed a teleportation circle in the basement there." Colin explained.

"You haven't been back to the Mage Tower much in the past six months, just studying at Cambri Regis Academy?" Tessa nodded.

"Yes, I forged an identity in Brighton to get into Cambriel School of Witchcraft and Wizardry." Colin sighed: "I have to say that the magic research of the Western Continent far surpasses that of our Tulum, and the two great magicians of Ebbs and Ovitel have inspired me a lot in many aspects.

"By the way, I also passed the intermediate level by the way, but in the capacity of Cohen Snape."

"Cambrig's Demonic Pattern Department is originally the first in the continent, and the two Excellencies Ebbs and Ovitel are the best masters of Demonic Patterns." Tessa smiled: "But my junior brother is not an ordinary person, after reading all the courses in half a year, I'm afraid no one can do it." ”

"It's okay, it's just breaking the history of the school since its founding." Colin said modestly: "However, the graduation assessment score can only rank second in history." ”

"Who's the first?" Tessa was curious.

"It seems to be sixty years ago, and the school didn't announce the name of that person, so there may be some hidden secret."

Colin reached out and touched the frame of the Wind Collider and sighed, "If it weren't for these half a year, my space magic would not have progressed so fast. ”

Colin didn't go too far.

Although he was a disciple of Roman Sagan, and the resources of the entire Tulum were taken from him, the gap between the Southern Continent and the Western Continent in terms of magic research was too great, causing his learning process to slow down in the end.

Going to the Western Continent was a planned thing.

However, for Colin, although he was largely taught and inspired by mentors such as Ebbs and Ovittel, self-study was still the most effective way to learn.

Therefore, Cambriggi attracted him the most to the college library.

It's a pity that half a year is too short, he just roughly read some literature and books that helped him a lot, and a lot of materials are set with permission, although he is the rising star of the academy, but after all, he is only a student, Cambrigi is not a Tulum Magicians Association, he will not be given too many privileges in this regard, plus he finally rejected the other party's invitation to stay in school, it is impossible to make any more requests.

"But why did you choose to go to Ilya?"

"Ilya has one thing I desperately need."

Colin didn't explain carefully, not because he didn't trust Tessa, but because it was useless to talk about it, it only increased Senior Sister's worries and concerns.

On the other hand, a bigger reason for bringing in Senior Sister to help is that he has to spend a large part of his time on the Western Continent side, and the fortress side will naturally often lose sight of others, and the cost of teleportation is not low, so it is impossible to carry it out frequently. After a long time, someone always needs to cover it up for him. And Tessa, who knew about the existence of the teleportation array, was obviously the best candidate.

Colin continued: "In addition, the geographical location of the Duchy of Banner is also very important to Shaya. ”

He said as he walked over to the map on the wall.

"It is located at the junction of the western and southern continents, and is one of the few land passages connecting the two continents."

"You've decided to open up the old trade routes?" Tessa was not stupid and immediately understood Colin's intentions.

"The resources around us are too limited, and if Xia Ya wants to develop, trade with the Western Continent is an indispensable link." Colin pointed to a line added to the map and said, "This trade route was used decades ago, but then as Duke Oliver's energy gradually faded, he could no longer care about it.

"Of course, the main reason is that Shaya didn't have anything to attract the Principality of Banner before, so naturally it won't be over."

"And now?" Tessa asked.

"Senior sister, I'll take you somewhere."

……

Inside the Alchemy Workshop.

Tessa looked at the various unfamiliar machinery and instruments, all kinds of chains and swing arms in front of her, and was a little distracted for a while.

"This is the first project to be put into practical use in mechanical engineering after the initial realization of the idea of 'magic energy'." "If I had to give it a name, I would call it an automatic arrow machine, which, as the name suggests, is a machine that can make arrows automatically," Colin said. ”

"It's funny."

Tessa only really saw something famous at this time.

The rough-machined log enters from the head of the machine, which occupies the entire length of the workshop, and is continuously divided into small pieces to form the thickness and length of the arrow, and then polished and fine-processed, soaked, oiled, feathered, and installed with the arrow, which originally required several workers to be responsible for the process, which was automatically completed in a short time in front of Tessa.

She walked to the exit of the finished product, picked up a finished arrow, and took a closer look.

"It's still rough in all aspects, and it doesn't need to be continuously improved." Colin explained.

"It's already pretty good." Tessa nodded.
