"Impossible!" Konstantin replied instinctively.

He rushed over in a bit of a frustration, Bruce put up the densely written tome in his hand and blocked it between the two, Konstantin took two steps back as if he had been punched, covered his forehead and said, "No, don't show me this, but there can't be a problem with my circle."

Constantine sat opposite Bruce, clenched his hands into fists, knocked on the table with his knuckles and said, "Although the power of the magician is borrowed, how to use the borrowed power is also very good.

"The difference between me and them is that I have mastered almost all the methods that exist to increase the efficiency of magical energy, whether it is chanting, charms, magic items, or magic circles, I have mastered the most subtle of them."

"This is also the reason why I borrowed all over Heaven and Hell and never repaid the money, but I can still live until now, I can achieve the maximum effect with the least amount of energy, and the energy utilization efficiency is at least five or six times that of others, if I let that group of fools who don't know a single rune come, I would have played myself to death a long time ago."

"But the two magic arrays you drew in front of me that day are indeed inefficient, and you only need to add less than four more transformational general runes, and the speed of energy transformation can be increased by 1.5 times."

"Hiss······" Konstantin gritted his teeth and inhaled, he glared at Bruce and said, "What a big breath, I'll go get the paper, and we'll start from scratch."

Konstantin rushed upstairs in a rage, brought a stack of white paper and a few pens of different colors, spread the paper between the two, and took a black pen to begin sketching.

He drew the magic circle very quickly, and in one go, without modification at all, he looked very proficient. Then Constantine pointed to the center of the magic circle with the tip of his pen and said, "Look here, when the magic energy is injected into the first branch of the devilish rune, the devilishishy acts on the last branch of the devilish, and conducts the energy to iabolus to form the first complete secret word "evil-demonic", as the first definition of this summoning, and the object of the summon is limited to the demonic ······".

Konstantin deduced a circle along the entire magic circle, the logic was smooth and complete, but Bruce shook his head, he took another piece of paper, and drew a more complex magic circle on it, and instead of using the usual circle or hexagon, it was a special-shaped magic circle, and the whole was a diamond shape that was narrow at the top and wide at the bottom.

"First of all, we write the Duo-Aura parallel rune from the Upta school in 556 AD, and then directly inject energy into the first branch of the upper rune, so that the first branch of DevilishY and the first branch of Iabolus travel at the same time, and then connect to the first branch of Fortuna to determine that if the opponent is devilish, then ······."

"Wait a minute!" Konstantin interrupted, pointing to one of the runes and saying, "What's going on with this parallel rune? Why is it so complicated?"

"This is what was just written in this book, and the duo-aura demonstrated by the Upta school formed around 500 A.D. was engraved on the Uptan Knight stele at the bottom of the Tigris River, and its characteristic is that the first branch of the rune is divided into a diversion after the energy is injected, so the branch pattern is formed here······

"You can memorize a hellish little rune carved on a goddamn stone tablet in the 500th year of the year AD??!!

"Yes, and the person who carved the last rune on it was Satus Upta, of the Upta School... ...」

"I don't want to know anything about the Upta School! I just want to know, why do you say this circle is more efficient than the one I draw, have you tried it?"

"It's not a matter of experimentation, it's just a matter of logic, and it's more efficient and inaccurate, and it runs faster."

Konstantin let out a puff through his nose, he slapped the table and stood up, saying, "You wait."

After a while, he took out a staff from the warehouse, looked at Schiller's unkind gaze standing at the table, and explained, "The magic props were made a long time ago.

The remaining magical energy on it is enough to run a magic circle, as long as I don't borrow a new one, it's perfectly fine."

Schiller looked him up and down, and Konstantin gritted his teeth and said, "You must give me a chance to have an academic exchange with your outstanding graduates, Professor Schiller?!"

He bit the last name very hard, and Schiller raised his eyebrows, took a step back slightly, and said, "Please."

Konstantin put the staff on the table with a "snap", he looked at Bruce and said, "I won't bully you, let's draw a miniature circle with the most basic pine ash, and then inject energy into it to see the result."

"Wait." Bruce interrupted him. "Why, don't you dare?"

"It's not." Bruce stared at the circle he had drawn on the paper, and said, "I remember Master Upta once suggesting the possibility that a parallel circle is not the end as long as the nature of the material can withstand it.

"In his lifetime, he wanted to experiment with double or quadruple parallel runes, but there weren't many magical materials in those days······ Do you have any circle materials that can withstand more power? I just had a new idea for four parallels."

Konstantin's eyes widened, he looked at Bruce in a daze and said, "You don't think you created a new circle, do you?"

"It's not about creating." Bruce's gaze remained on the paper, and he said as he thought, "It's just an improvement, if parallel commands can be done, then dual parallel commands can definitely be done, but I don't know exactly how the nature of magic materials is different right now······ Do you have a book on this? I feel like I can memorize them in the last twenty minutes."

Bruce glanced up at Constantine's expression, stood up as if he was helpless, and said, "Okay, then let's try the existing patterns first, and if I can, maybe I can try to add the double parallel runes on the way to the banquet."

Konstantin grabbed a handful of pine ash and sketched his circle in a smooth manner, then handed the bowl to Bruce.

Batman is a man who can throw completely ergonomic and aerodynamic bat-shaped darts out of flowers, and even for the first time he draws a magic circle, he doesn't panic and shake his hands, holding a little pine ash in his hand, and he doesn't pause from beginning to end.

After the circle was drawn, Konstantin took the staff, looked at Bruce and said, "Will you come or will I come?"

Bruce made a gesture of please, and Konstantin placed the gem on the tip of his staff on the rune that needed to be infused with energy, and a faint light flashed, almost instantaneously spreading through the circle drawn by Konstantin.

The light on the circle became stronger and stronger, and the original white light began to gradually become colored, and after about five seconds, the circle turned completely red, and only went out after ten seconds.

Then, in the same way, he poured energy into the circle drawn by Bruce, which began as a faint white glow and turned crimson in less than two seconds.

Konstantin's brows furrowed more and more, and then his eyes suddenly widened, and he quickly used the bottom of the staff to riot the magic circle, but it was too late, and the demon's whisper came from the center of the circle.

"It's over, it's time to meet the minimum requirements for summoning!"

Konstantin's voice was flustered, but his movements seemed to have been rehearsed a thousand times, and he took a step back, his dantian in a deep breath, and his hands held the wooden staff.

"Whoosh! Bang!"

The rounded staff smashed straight into the horns of the demon that had not yet had time to emerge, and the demon's scream echoed in the fading light of the magic circle, "Konstantin!!"

Konstantin put away his staff, plucked out his ears, and said, "What are you shouting, if I can use magic, I will definitely let you up······

Bruce raised his eyebrows in surprise, then looked at Konstantin and said, "Looks like I still have a lot to learn.

Konstantin paused, looking a little surprised, and said after a few seconds with a grin.

"You don't have to, boy, you're more powerful than I am, just remember, do it all at once

They smashed it back, and that was the only way to cancel the summoning ritual."

Then he stepped forward and patted Bruce on the back and said, "You may really be a genius in the wizarding world for a thousand years, maybe you can compare to Merlin, but sometimes it's useless to hang a bookbag, and it works best to smash the demon and then negotiate."

"Of course, that's our school's housekeeping skill, isn't it?" Bruce smiled at him and said.

Konstantin was slightly stunned, he turned his head to look at Schiller, who was leaning against the bookshelf table, Schiller raised the wine glass in his hand to him, and Konstantin's eyes immediately straightened.

He rushed over, sat down across from Schiller, and said, "Don't tell me that you have an infinite supply of red wine in your mage's tower?!"

"Besides, the cigars, the good stuff in my office."

"You said earlier, where did our school's mage tower go? It can't be Gotham, right?"

"Of course, it's not that if the mages go crazy, I'm afraid it's not very conducive to academic exchanges, I think this bookstore of yours is good, and the back is the Forgotten Bar, with a beautiful environment and convenient transportation, what do you think?"

"You're going to bring the stock here?"

"That's up to you to prepare a wine cellar."

Konstantin stood up at once, hurried to the basement, and said, "It will be built in three days, I am waiting for your good goods!"

Schiller smiled, stood up from the table, looked down at his watch, and said, "It's almost time for the banquet, let's go."

While waiting for the carriage in front of the bookstore, Schiller turned to look at Bruce and said, "It is indeed a good way to win the trust of the other party by provoking them with straightforward language in the areas where they least want to lose, and then expressing humility and willingness to learn from the other party after victory."

When Bruce looked back, Schiller looked him in the eye and said, "But sometimes the mundane is more moving."

The carriage descended from mid-air, and Schiller and Bruce sat in the carriage, and Schiller looked out the window at the night and added, "The enjoyment of sound, sight and taste is an innate human instinct, and few people are exempt from vulgarity."

"Are you suggesting that I will give you a bottle of red wine?"

"So, boy." Schiller turned to Bruce again and said, "You still have a lot to learn.

The magic carriage streaked across the misty night sky of London and headed towards the point of light on the shoreline, until the last glimmer of light disappeared at the end of the sky, leaving only the city alone.
