In the blink of an eye, it was already winter, and when the outside world was covered with heavy snow, the deep blue was still warm as spring. According to Reilly's speculation, there must have been some kind of central air conditioning device in the main tower of the dark blue.

The abundance of books in the dark blue pleased Reilly. In order to increase his knowledge, he asked the system to copy all the books he could get his hands on. As he reads, Reilly discovers something that intrigues him: the Magic Pattern Build.

If the magic array is compared to an electrical circuit, then the magic pattern construction is equivalent to an integrated circuit, which is a product of highly developed magic technology, which can be loaded onto the human body, bringing some attribute bonuses or additional skills.

And the maker of this high-end product is known as the Magic Pattern Builder.

In the Norland plane, the status of the Builder is quite high. Because they created the ultimate combat unit of humanity: the Constructed Knight. Only units that have at least five Demonic Crafts loaded will be called Constructed Knights. In Norland, most Constructed Knights consist of four Constructed Knights and one Constructed Mount. After all, mounts that can carry two structures are too expensive, and usually only the powerhouses of the Sanctuary can afford to use them.

All other things being equal, a level 14 Constructed Knight can compete with an ordinary level 17 warrior, and the former is even more effective on the battlefield than the latter, because they are more likely to form numbers! On the battlefield, number is always an important factor that affects victory or defeat.

In the Norland Continent, the number of Sacred Domain powerhouses is limited, and each of them is the object of competition from various forces, and no one will run into the army to be cannon fodder. However, the individual strength of the Constructed Knights is not far from that of the Sanctuary, and more importantly, they are able to charge in groups on the battlefield, so this kind of force has become a strategic military force.

Ever since the first formed Constructed Knight unit appeared on the battlefield, this class has become a haunting nightmare for other races. Many famous military strategists have said the same thing: only a Constructed Knight can deal with a Constructed Knight.

As the most sought-after profession in the Norland continent, the number of constructors is extremely demanding, so the number is very rare. The Holy Alliance Empire has tens of thousands of warriors of about level 14, but the number of Construct Knights has always remained at about 1,000, the reason is that there are only ten Builders in the entire Empire.

Reilly had read a secret book in the Star Library that specialized in psychic powers, and had learned many useful techniques. When needed, he can completely replace his eyes and hands with mental power.

When observing objects with mental power, Reilly can magnify the objects he "sees" a hundred times, and the invisible hand constructed with mental power can also be precision machined, so that the magic array he draws is accurate to ten microns, that is, one thousandth of a centimeter. Even on Earth, Reilly has reached the minimum standards of precision machining. (On Earth, precision machining refers to machining technology with a machining accuracy between 10 microns and 0.1 microns.)

And as the mental power grows, this accuracy will continue to improve. It can be said that there is no bottleneck at all in Reilly's path to being a constructor, as long as he completes the accumulation of mana and knowledge, he can naturally improve his rank.

In order to master the production method of the magic pattern construct, Reilly took many niche courses, and most of them were directly or indirectly related to the magic array. Sometimes, he even found that there were only two cadets in certain subjects: himself and Richard.

Richard was the handsome young man Reilly had seen on his first day of class, one of Helen Su's personal disciples. The child was very silent and always seemed melancholy. Reilly hadn't seen Richard smile since he had known him.

With the exception of Reilly, Richard never interacted with the rest of his classmates. Even during recess, he was looking at his notes and handouts, or discussing magic with Reilly.

Reilly was delighted to see this new friend. On the path of exploration and discovery, a like-minded partner is more valuable than anything else. Of all the students, only Richard could get Reilly's approval. In fact, vulgar people who are bent on using magic to gain wealth and status can hardly have anything in common with pure scholars like them.

As a result, Richard became Reilly's second friend in Deep Blue, and Richard was the only friend of Reilly.

On this day, Erin hurried into the dark blue public library and pulled out Reilly, who was reading.

"Did something happen?" Reilly looked blankly at the anxious girl.

"Richard is about to have a magical duel!" Irene answered his question as she pulled Reilly towards the arena.

"Oh, who's that?" said Reilly, who was interested.

"That man's name is Papan, and he's a first-class magician. ”

"What, this duel is not interesting at all, that guy will definitely be killed by Richard in seconds. Reilly shook his head and said.

"Why?" asked Erin, confused.

"Because Richard has already learned the fireball technique. ”

Fireball is a legendary level 3 magic spell with an irreplaceable importance. The cast time of the three-second spell is not too long, the basic range of thirty meters is not too short, and the lethality and attack range comparable to that of a high-explosive grenade, the fireball technique has the capital to be proud of the same level of magic. When it comes to level five, most mages will choose Fireball as the first level three spell they learn.

"Hey~~~?!" Erin exclaimed in surprise: "But Richard is still a first-class mage!"

"Why are you so surprised? Isn't it normal for a legendary mage's personal disciple to be stronger than ordinary people?"

"But that's too much stronger, isn't it?"

"That's the difference between a genius and a mortal!"

"That's right......" Erin looked a little lost, as if she had been hit.

Soon, Reilly stood in the aisle of the dueling arena, pointed to the crowded audience and said to Erin, "Do you think these guys are full of food and have nothing to do? ”

"Didn't you come to see it too?"

"You pulled me here. Reilly quibbled, "Besides, those guys actually filled their seats so quickly, which is really low-level fun." If you want me to say, they just want to see Richard make a fool of himself. Reilly was right, and one of the things that the masses loved to see was to see the lucky ones fall into the dust.

"You didn't get a seat, but you can't say that to anyone else. Erin smiled wryly.

"It's called anger. ”

"Don't be so arrogant!"
