The smoke of incense floated slowly, dimming the candle light on the walls, the faint footprints on the heavy cashmere carpet, and the cacophony of the feast reaching its climax came from outside the door.

Behind the screen were many satin upholstery, the delicate metal wine glasses that had been placed on the table had all been moved to the back shelf, and the rustling of writing and the occasional faint sigh could be heard in front of the table.

Crisp footsteps came from outside the door, followed by the "creak" of the heavy wooden door being pushed open, and a woman's hand with dark nails rested on the edge of the screen.

With a "bang", the screen was pushed open, and a surprised female voice sounded, and a glamorous lady in a gorgeous red gown, black hair and green eyes, looked at Bruce's blue eyes as she looked up from the table.

"I'm sorry, ma'am, is there anything wrong with you?"

"God, aren't you that student of Dr. Schiller? Why are you here? Didn't you go for a drink with your teacher?" The lady gently covered her mouth with her fingers, looking surprised.

"There's a bit of a noise in there, I just came up with an idea, and I'm trying to verify it, so I found a place where no one is around, and bothered you?" Madame?" Bruce kept looking up at the lady as he spoke, his eyes were very focused, so even when he looked from below, he didn't seem flattering.

"Oh no, I'm going to say sorry, it looks like I've interrupted your research······ You can call me Mrs. Shangdu." The lady smiled slightly and said, "They all call me that, because I used to live in the Shangdu of the Yuan Dynasty."

"Hello, ma'am, I don't have anything to do here, you don't have to worry, you can go back and enjoy your banquet." Bruce lowered his head and straightened the wad of scratch paper in his hand, staring at the pattern he had drawn, and frowned again.

But Mrs. Shangdu had no intention of leaving, she walked into the screen, then knelt down opposite Bruce, looked at Bruce's face carefully, and said, "Haven't you heard of me?"

Bruce looked up at her again, and then he found that whenever his eyes met the eyes of the lady of Shangdu, he would instinctively froze for a moment, so he asked with some curiosity, "What's the matter, ma'am?"

"Nothing, it's just······ It's just that your eyes are a bit like one of my old friends." Mrs. Shangdu pursed her lips and smiled, and said.

"My teacher told me about you, but he said it wasn't rude to comment on a lady behind my back, so I didn't know about you."

"Dr. Schiller always does." Madame Shangdu shook her head and said helplessly, "Always keep a very polite distance from everyone, the last time my sister Vivien asked me about him, I couldn't even make up three sentences."

Bruce adjusted his sitting posture from a relaxed two-legged sitting position to a standard sitting, and Mrs. Shangdu raised her eyebrows, showing a somewhat surprised expression, and said, "You're Bruce Wayne, right?" You're a little different from what is written in the newspaper."

"I don't have time for those things." Bruce turned his gaze back to the manuscript paper.

He guessed that there must be many young mages in the wizarding world who were addicted to magic and behaved a little out of place in ordinary society, and he planned to make himself into this image, so he shrugged his shoulders rather frivolously and said, "I don't have the time to chase tabloid reporters all over the world and ask them to understand me."

Mrs. Shangdu laughed and said with some amusement, "Then what is the matter with you and those beautiful models?"

"Personal hobby." Bruce pursed his lips and said bluntly, "I do have a lot of female companions. I love their beauty, they love my wealth, and we take what we need, and who knows that the people who write these stories don't have a hint of jealousy when they type?"

Madame Shangdu laughed even harder, and she could even be called leaning forward and backward, she covered her mouth with one hand, and there was a subtle beauty of the East, and then she looked into Bruce's eyes and said, "Boys are always like this, they don't know the charm of youth and straightforwardness, and they are like murderous blades."

Bruce lowered his eyes without moving, and returned his gaze to the scratch paper, and his repeated actions finally attracted it

Mrs. Degdaldu set her eyes on the circle he had drawn on paper.

Mrs. Shangdu originally thought that he was copying, so she did not look closely but only glanced at it, but when her gaze passed the scratch paper, she paused.

"What are you drawing?" Madame Shangdu narrowed her eyes slightly, staring at the slightly unfamiliar pattern of the circle on the scratch paper, and said, "Create a new circle? Is this the result of your teacher?"

Bruce shook his head, as if he was a little angry, and said, "No, this is the homework he left for me, ma'am, I'm not sure you want to hear all that boring academic material...

"Tell me about it." Madame Shangdu rested her chin on her fingers, nodded very reservedly, and said, "Maybe I can give you a little help······ Oh, if you don't know who I am, then you always know who King Arthur is, right? Vivien, the fairy who gave King Arthur the sword in the lake, is my own sister."

Bruce's pupils narrowed a little, and Mrs. Shangdu looked at him with satisfaction on his shocked expression.

"Then you must help me." Bruce immediately leaned forward, then turned the scratch paper upside down and put it in front of Mrs. Shangdu, and said very sincerely, "I'm going to turn in my homework tomorrow morning, and if I can't finish it, I'll die."

Madame Shangdu laughed out loud, shook her head, and said, "You dare to be a student of Dr. Schiller, you are really bold, and everyone in the circle knows that he is not very good-tempered."

"It's not just bad." Bruce muttered under his own breath on purpose, and then looked at Mrs. Shangdu with a distressed gaze.

Mrs. Shangdu then turned her gaze to Bruce's scratch paper, her expression was relaxed for the first thirty seconds, and after a while, she frowned slightly, and after about two minutes, her brow became tighter and tighter.

"Bruce, I can call you that, right? Are you studying the Hopta School's multi-line parallel rune ciphers?

"Oh my God, ma'am, you were the first to see my choice, so do you have any research on it?" Bruce immediately showed eagerness as if he had seen a lifesaver.

Madame Shangdu shook her head slightly, but nodded again, she sighed softly and said, "I have met the descendants of Master Upta, but he is no longer studying such obscure knowledge, boy, let me ask more, what are you doing studying this?"

"It's not what I want to study." Bruce pursed his lips and said, "This is Professor Schiller's chosen subject, and I can only finish it."

"Okay, it seems that he deliberately made things difficult for you, even in the magic world a hundred years ago, there were not many people who studied this topic, you must know that multi-line parallelism means that you have to be familiar with multiple secret word chains at the same time, as long as one of them goes wrong, there will be problems in the future."

"Exactly, ma'am, do you think this magic circle of mine can run smoothly?"

Mrs. Shangdu stared at the magic array, tilted her head and said, "The first rune of this magic array you drew is a double line parallel, and after receiving the functional rune, you will connect these two runes and two more double lines to become four, you have repeated this process more than a dozen times, and the entire magic array has become so complicated that I will not understand it for a while."

Madame Shangdu drew the lines on the paper with her fingers, and said, "It's not a good thing that the magic array is too complicated, every link has the possibility of mistakes, if there are too many links, the probability of errors will be greatly increased, which is also the reason for the decline of the Upta School."

Bruce sighed and said, "I don't have the ability to verify whether this magic array can work, so I don't know what Professor Schiller's evaluation will give tomorrow morning, if only I could test it in advance."

"Who are you contracting?" "Belial."

Mrs. Shangdu showed a helpless wry smile, she looked into Bruce's eyes and said, "Didn't your teacher suggest that you change the contract partner? Belel has been lost for a long time."

"But that could be more costly, so I have to get a good result first." Bruce pushed the scratch paper forward again, stared at Madame Shangdu with those blue eyes, and said, "Madam, could you please help me verify the feasibility of this circle?"

"Yes, yes." Mrs. Shangdu nodded and said, "

I owe Dr. Schiller a favor, and so does Master Andrew, but I have to ask first, what is this circle of yours for?"

"Just a simple demon summoning circle." Bruce nodded and said, "And it may not be fully operational."

"Okay, so do you want to experiment with a miniature circle, or do you want to draw the original scale of the large circle?"

Bruce pinched his chin with his hand and thought for a moment, and finally said, "Although the effect of the Great Circle is better, it would be too much of a waste of your power, just draw a small one."

Lady Shangdu smiled and said, "You underestimate Maia's fairy clan a little, we are not like humans, our energy comes from natural origins, and besides, the magic circle that a magic apprentice has written to summon demons is not enough to affect my mana reserves."

"Thank you so much, ma'am." Bruce stood up, as if he couldn't wait to experiment.

Madame Shangdu shook her head, as if lamenting that the young man could not bear it, but she still led Bruce downstairs, while the white-haired Master Andrew was still drinking, and Schiller was sitting beside him and chatting with him.

"Dr. Schiller, your apprentice is mine." Madame Shangdu smiled and waved her hand at Schiller and said, "Don't worry, I won't eat him."

Schiller raised an eyebrow but waved his hand to let them go, and Master Andrew, with his messy white hair and mustache, shouted over there, "Hey, young man, don't listen to her, the fairies of the lake eat people!"

Mrs. Shangdu snorted coldly, then beckoned to Bruce and said, "Come with me, let's go to the back garden for experiments, Andrew's storehouse has a lot of good things, the ring you brought is very much to his liking, he won't be stingy with you."

After saying that, she took Bruce into the back garden of Andrew's Mage Tower, and then took Bruce to dig out a lot of materials for arranging the magic circle in Andrew's storeroom.

"I'll come, ma'am." Bruce took the material from Lady Shangdu's hand, and began to sketch a huge magic circle across the garden floor in an extremely fluid motion.

Bruce's hand was steady, but he would stop to think in the interval between the sketches, and Mrs. Shangdu was a little fascinated as she watched, and she and Bruce stood together to discuss the role of these parallel and amplified runes, and modify them to perfection.

After the magic circle was drawn, Madame Shangdu flew up and looked down on Bruce and the fruits of her labor, it was an extremely complex and huge magic circle, containing many difficult and obscure ancient runes, and Madame Shangdu could only understand a small half of them.

After she landed, she sighed, "If you are really a famous teacher and a high apprentice, I have never seen a young mage with the same knowledge as you, or rather, your ritual level is one of the best in the entire magical world."

"You've won the prize, ma'am, let's get started."

In hell, Beelzebub's palace was also a scene of lively banquets.

Countless gifts from demon generals were piled up into a high mountain, and the water from the blood fountain fell on the bone-paved road, and all kinds of demons sang and danced, merry and enthusiastic.

But the Lord Beelzebub on the throne stared at the few small figures in front of him with a very dissatisfied gaze, and he snorted coldly and said, "Batman received my invitation, but he didn't come, but sent a few of you human cubs over, and he didn't take the monarch of hell seriously!"

Standing in front of him were the three Robins, Nightwing, Red Hood, and Red Robin swallowing in unison.

The impact of facing the Demon Monarch was not ordinary, and when Beelzebub's huge Demon Phantom was staring at them at the same time, the pressure was even greater.

"It's true that Batman can't come in person, but we can congratulate you on his behalf······ Nightwing stepped forward. "What could be more important than my celebration?!"

As Beelzebub's rumbling voice resounded through the palace, Robins noticed that the demons around them looked at them with a bad look.

Just as the demon generals gradually gathered around, Beelzebub on the throne was suddenly stunned for a moment and muttered, "... who

？」

"Who's calling me? I don't have an agent, do I?" Beelzebub spoke in a very confused tone, and then he said impatiently, "I've got something to do, wait!"

Suddenly, Beelzebub's expression froze, and a black vortex suddenly appeared on the right side of his body, and one of the corners of the huge figure covered with a thick black mist began to tilt to one side as if it had been grabbed by something.

Under the gaze of Robin and countless demon generals, Beelzebub's entire demon was dragged away with a "whoosh", and then the entire demon king's palace began to shake.

In Andrew's Mage Tower, Lady Shangdu was emitting green light, pressed her hands on the magic array, turned her head to ask for help, and said to Master Andrew who hurried over, "Andrew! Save me! I don't have enough strength, but I can't let go, and if I continue like this, I'll be drained!!

Andrew hurriedly took two steps forward, raised the staff, and a strong light shot out from the top of the staff, and in an instant, a rich energy was poured into the circle, he wanted to destroy the rune and invalidate the circle, but in the next second, he was also stuck there and completely unable to move, and fell into the same situation as Mrs. Shangdu.

With the infusion of more and more energy, countless double-line parallel runes began to exert force, 2 to 4, 4 to 8, 8 to 16, more than a dozen exponential growth and countless enlarged runes in series, so that the effect of this magic circle reached a terrifying level.

A huge vortex appeared at the top of the mage tower, and a rich demonic power poured out, and the entire sky was dyed black, and just when the output value of the magic circle reached its maximum, there was a "bang", a huge evil with more than a dozen pairs of eyes

The demon was planted headlong, and then there was the demon general who was like a dumpling.

The last few Robins who fell down stood up with their heads in their hands and looked at a slightly familiar figure and walked towards the biggest demon.

And Beelzebub, who had been planted, had just opened dozens of pairs of his eyes, and he stared at Batman. Then, he heard Batman say:

"I'm sorry, Your Majesty Beelzebub, I really don't have time to attend your daughter's wedding, so I can only let you come here once."

"Also, on this great day, do you intend to choose a pope among the earth to share your worries?"
