Chrissy looked at Ulysses beside her with some admiration, she had only understood less than a tenth of what Ulysses had been on that blank piece of paper just now, but it had opened her eyes, and she even felt that a new world of mathematics was opening in front of her.

The remaining nine-tenths of the time, Chrissy was completely misty, but judging from the previous one-tenth that she could understand, there was no doubt that they were extremely advanced or even more mathematical theories than this era, and it was hard to imagine that these were written by Ulysses in less than ten minutes.

Even if it's a badass, this guy is a super intelligent badass, Chrissy affirms that.

"How the hell do you understand those problems?" Chrissy understood the part about the three graphic problems, and after Ulysses' anatomical analysis, she finally knew why these three problems could not be solved directly with a ruler.

Because those three problems are originally beyond the problem of making a ruler and a compass, the idea of trying to solve these three problems with a ruler and compass was a big mistake from the beginning.

But who would have thought of this question from the beginning, these three problems seem so simple, it seems that as long as you have learned to make pictures, you can draw them. But after real research, it will be known that it is completely impossible to complete these three problems with a ruler in a limited number of steps.

Sometimes, the easier the question, the harder it becomes. Even though Ulysses had written the answer to why it was impossible on that piece of paper, until much later, there were still people who did not give up trying to find the impossible answer in the scope of the ruler drawing.

"Actually, I read it in a book. Ulysses said as a matter of course.

"There is an answer in the book, what is it?" Despite being overseas, the library of Seven Nights has never stopped expanding, and even many books that have long been lost in the human world can be found in Seven Nights, and many new books on magic and mathematical theory on the mainland will be collected into the library of Seven Nights every year.

However, Chrissy didn't have any memories related to these three problems, otherwise she wouldn't have been fooled so easily and tried a helpless failure.

"Yes......" Ulysses paused abruptly, and was shocked to find that he couldn't remember what book it was.

How is this possible, when describing why those three problems could not be illustrated with rulers, he wrote down a large number of verbal proofs and theories almost without thinking, these things are obviously extremely advanced knowledge, undoubtedly it should be the knowledge he has read from which book, but why can't he even remember the name of the book.

Searching as hard as he could, Ulysses remembered almost all the titles of the books he had read during his hard studies in Taji, but none of them contained such advanced mathematical knowledge. The number of such books published is so small that it is said that it is only circulated in the time of those who are real scholars, and they cannot be bought if they want to.

Later, until the end of the Warrior Conference, he also bought some books from bookstores, and occasionally bought a few pages of books that recorded divine arts, but none of them were related to advanced mathematics.

Ulysses recalls the books he read when he was Jusses, and there were indeed many books on advanced mathematics in the water sage Cavendish the sage, but his memory was so blank that he even forgot how to write the words, how could he read those inscrutable math books.

The next few months of his studies at the Radiant Academy were undoubtedly the fastest growing months of his life, but not even in the large library of the Ana family, he had not seen a book containing similar mathematical theories.

Why, he can write those complex mathematical formulas and theories as a matter of course, and he has not read any books that record those knowledge in his memory.

This phenomenon is not the first time this has happened recently, just like when he saw the two maids beside Lisy just now, he couldn't help but feel a sense of nostalgia in his heart, as if something he had forgotten was slowly waking up in his body.

It was like a sprout growing back from a burned ruin. What has been forgotten, what has been lost, is revived little by little from the deepest part of the heart.

Warm but with a touch of old and lonely, he became a little less like himself. I know who I am, but I always have the feeling of looking at myself from the perspective of a third person.

Everything I experienced was spinning in my mind like a roulette wheel. Picture after picture becomes a clear image and is reproduced.

During his childhood in the village of Mira, his studies in Taji City, his encounter with the Apostolic Order, and his search for the power to resurrect Yulia in the Radiant Academy, there are several gray and unknown places in which he has lost his memories and forgotten pasts.

Especially the summer of that year, the summer when he lost Yuria, was almost entirely occupied by gray, and most of it was no longer visible.

He was wrong, he didn't really remember everything about that summer, just like seeing Angela in Sister Mira's dream and only knowing that the two had met at that time, he had forgotten too much about that summer.

His memory was as if it had been cut off by some irresistible force, and it was already incomplete.

Ulysses had known about this for a long time, but it was the first time he had seen his mutilated parts so clearly. If his life were to be written in a single album, there would probably be dozens of incomplete parts of it, and no matter how good a painter could complete them.

As Ulysses tried to uncover the truth about these incomplete parts, his body suddenly trembled violently.

It's so cold, as if the soul is going to freeze, and the cold spreads from the lost parts. This is the death and cold that contains thousands of years of loneliness, and the pain that he can't bear, just a little touch, his heart seems to have fallen into an ice cave.

If it weren't for the more warm treasures in his heart, and the memories of being with Laxia, Sister Mira, and everyone in the Apostolic Order, I'm afraid that as long as this moment, he would have entered that cold world.

There is no hope or warmth in that world, there is only boundless dead silence, as if the world has long since ended and the future has been cut off.

"Are you alright?" Chrissy noticed that Ulysses's face was now very bad, as if he was seriously ill, and he could not even stand on his feet.

It's okay, I can get through it, I haven't fulfilled my wish to resurrect Yulia yet, how can I stop here.

Even if it turns out that way, it can't happen right now.

So, endure it, absolutely put up with it. No amount of sadness, no amount of sad memories could stop his determination. You can't fall here, you can't go to the world over there.

Now, it's too early.

Ulysses gasped for breath, and by the time he noticed, Chrissy had led him to a shop where he bought various masks, and was curiously and playfully picking among the various animal masks.

"Look at you as if you are dying, but it's not like you just now, you have solved all such difficult problems, which makes me more ambitious. Chrissy picked up a white fox mask and put it on Ulysses' face.

The icy touch combined with the faint girly scent allowed Ulysses to escape from that miserable and cold world and return to the real world.

Sure enough, it was still here that made him feel more at ease, even if that world made him feel like "he will go back eventually", but for him, there were more important things in this world, and the people he wanted to protect and the wishes he wanted to fulfill were all in this world.

So he can't go there yet, and he can't accept the coldness and loneliness, not because he is afraid, but because there are people here who he really wants to protect and save.

Even if he had to go back one day, it would be after his wish was fulfilled, not now.

"Thank you!" Ulysses genuinely thanked Chrissy for bringing him out of the cold nightmare he had just had.

She probably didn't know what a great thing she had just done, and for Ulysses, it was the perfect amount of saving her life.

Not delusion, neither absurdity, but when he came into contact with that coldness, Ulysses felt that his spirit and will were being drawn to it.

Thousands of years of loneliness and coldness, everything is as lonely as nothingness, and for him he doesn't know why there is an uncontrollable temptation.

Like, that's how everything should be.

It seems that the world could have been unreal, but he himself has always refused to believe it.

It seems that the world over there represents the final truth, the answer to everything.

But Ulysses didn't want to go there, because he still had too many things to let go, even if that was the real truth. He vaguely realized that once he went to that world, he would never come back, and he had to say goodbye to everyone.

"Weird guys. Chrissy chose a white fox mask that was similar to Ulysses', but it was cuter and just right to match the one Ulysses was wearing.

In fact, it's a couple's mask, but Chrissy doesn't notice it at all.

Throwing away the cloak that covered her face, Chrissy turned around happily with a small and cute fox mask, and then stood in front of Ulysses with the same mask with her hands on her hips, her long ponytail swaying, full of girlish vitality.

"It's time to go, if it's a man, just give me a little bit and pretend to be sick!"

"Got it, I'll have fun with you tonight. Wiping the cold sweat from his forehead, Ulysses stood up easily and stretched out his hand to Chrissy:

"Let's go, princess. ”
