"Different? What kind of problem will even the cunning devils be helpless?" After hearing Roger's words, Saint Sarana couldn't help frowning, her face full of disbelief. The great magician Ian also had a little doubt on her face.

Although he is on a hostile position, under the long-term confrontation, the major forces in the Elia continent have sufficient understanding of the devil and the demons, and among them, the devil's cunning and the demon's strength have been recognized.

Moreover, it is said that the magic knowledge obtained by the initial magicians came from those cunning devils. Therefore, for a long time, the Church of Gods had fully wanted magicians on the entire continent. It was not until the strong rise of the Nine Ring Tower that the current magicians completely abandoned many bad habits that the status of magicians was finally recognized by major forces.

Even so, the Nine Ring Tower and the Church of the Gods still preserve many puzzles left by the devils, and no one can solve them until now.

Therefore, Saint Sarana and the Great Magi Ian didn't believe that Roger could ask any problem that even a cunning devil could stump.

"Your Son of Nature, I believe you should be clear. Puzzles without answers cannot be used to build magic seals!" The great magician Ian reminded me solemnly.

"Of course I know this." Roger raised his eyebrows, and the smirk on his face became more and more obvious. "These three questions are indeed difficult questions with accurate answers. However, even if the devils know the real answers, they may not be able to untie the magic seal I designed."

Saint Sarana and the great mage Ian couldn't help but look at each other, and they could see the curiosity in each other's eyes.

"Can you tell me in detail?" Saint Sarana asked very directly, while the great magician Ian, Desperate Knight Gero and others all raised their ears.

Obviously, everyone is full of curiosity about these three problems.

"Of course." Roger nodded with a smile.

Such an inquiry is obviously inevitable. Saint Sarana would not agree to Roger to design the magic seal without knowing the content of these problems.

After all, to complete this task, everyone present must be prepared for sacrifice.

"Let's talk about the simplest one first." Roger's face smirked again, "This problem only requires a passage to be spoken accurately in a special language according to the rhythm."

"Um?"

Saint Sarana and others frowned: What is the difficulty of this problem?

"Ahem!" Clearing his throat, Roger glanced at everyone and said with a wicked smile: "This is what we have to read..."

"Old man Lu, a sixty-six-year-old, built sixty-six buildings, bought sixty-six baskets of oil, raised sixty-six cows, and planted sixty-six weeping willows..."

Roger spoke a long...ton twister in Chinese in his singing accent.

This long tongue twister is composed of dozens of tongue twisters. Even if Roger himself has to slow down and speaks slowly, he will inevitably make mistakes several times.

After Roger finished singing this tongue twister that needed to be recited for more than ten minutes, Saint Sarana and others had a little more pain on their faces.

After Roger began to recite the tongue twister, Saint Sarana and others, who did not take the tongue twister seriously, tried to read it with Roger. Then... without exception, they all bit their tongues.

"That's...what..." Saint Sarana said with a depressed and confused look on her face. After Roger recited this language she had never heard before, Saint Sarana was the first to follow Roger. For this unknown magic language that can cause the response of magic elements, every spellcaster must try to learn.

Saint Sarana's condition is still good. As the Saint of the Morning Light, she can use divine magic to treat her tongue even if she bites her tongue. The big magician Ian and others who bit more severely were in a tragedy. They could only wait for Saint Sarana to recover and help them treat them.

While Saint Sarana and the others were treating their tongues, Roger explained the "difficulty" with a wicked smile: "I believe everyone can hear it. This is a language that has never appeared on this Elia continent before. And the passage I just sang is a sentence called tongue twister, which is used by children to exercise their tongues."

"The difficulty of this problem is that to complete it, you need to learn this language called 'Chinese' first!" Roger put away the smirk on his face and said seriously, "With the abilities of demons and demon kings, it is probably not difficult to obtain relevant knowledge about this language. After all, many people in the Kingdom of Oaks have learned this language now."

What Roger didn't say is that most of the children who have learned "Chinese" now are just children who have mastered common characters.

"However, just mastering the relevant knowledge of this language and being able to simulate similar sounds in a rough tone, it doesn't work! You must know exactly what each Chinese character means!" Roger continued seriously, completely ignoring the look of Saint Sarana and others with the meanings of "You are the devil", "so terrible" and so on.

"Then, on this basis, you must read the tongue twister in a word within a limited time, which takes up ten minutes to recite." At this point, Roger smiled again, "In order to increase the difficulty, the creatures who want to solve this problem need to recite the tongue twister every time they try to remove the magic seal will be different!"

Saint Sarana and others no longer know what to say. However, although the difficulty of this problem has already exceeded the sky, Roger still felt that it was not difficult enough.

"Because the devils and demons can transform themselves to obtain a good voice and flexible tongue, and then fully master Chinese through learning, so on, based on the previous two, I added the third requirement." Roger smiled at Saint Sarana and others, which scared Saint Sarana and others, "You must recite this tongue twister according to the melody of a song!"

What Roger didn't say was that his very bad-hearted decision to use the melody of Hallelujah chorus as the melody of the tongue twister. Let the devil and the demons recite the tongue twister with the melody that praises God. It's fun to think about it.

Moreover, although the devils are extremely cunning, they have never heard of a devil with artistic talent.

With these requirements, this seemingly simple problem has actually become a problem that can be done theoretically, but in fact it may be done in a very small way.

After Roger finished speaking, Saint Sarana and others were looking at him with a look of "perverted" look.

After calming down, Saint Sarana said with a tangled face: "I believe that this simplest problem is enough to stump most devils, let alone demons with only muscles in their minds. However, with the strength of those demons, there may be demons that can meet your requirements. So, your other two problems will not be the same type, right?"

"Of course not." Roger smiled again, but the kind smile made Saint Sarana and the others subconsciously tremble their bodies.

"This second difficult problem is a math problem." Roger said calmly, but in the eyes of Saint Sarana and others, it seemed that two short horns had grown on his head.

"This question is like this." Roger said solemnly, "There is a man named Goldbach who proposed such a conjecture that 'an even number greater than 2 can be written as the sum of two prime numbers'! No one has proved this conjecture yet, but a great mathematician named Chen Jingrun has proved a theorem closest to this conjecture. Any even number is the sum of the product of a prime number and a no more than two prime numbers!"

"And the second problem is, please verify this Chen's theorem called 1+2!" Roger said with a serious look on his face.

"Guru."

Everyone swallowed a saliva, including Saint Sarana, who had always been elegant, which made the sound of saliva extremely loud.

Everyone looked at each other awkwardly, but no one spoke.

After a long time, Jerell, the Desperate Knight, sighed and said slowly: "I know every word you say, but why, when these words are combined together, I can't understand at all?"

Wiping the cold sweat that popped out of his head. The great magician Ian smiled bitterly and said, "I understand this question completely. However, although someone has already obtained the so-called 1+2 accurate answer, I still feel that I have no idea how to start."

Saint Sarana shook her head and said with a wry smile: "Although there are many scholars in the church, I believe that in another thousand years, there are probably few people who can prove this so-called 1+2. For the devils, this second question will definitely make them stunned."

Due to the threat of the magic disaster, although there is a profession of scholars on the Elia continent, such advanced mathematical problems must be proved by scholars who are proficient in mathematics.

Roger just smiled and shook his head. This question was also a difficult problem that he knew the answer and knew how to do it, but could not prove it. Similarly, Roger did not believe that there would be such a powerful mathematician among the devil.

Devil mathematician? This is really funny.

While imagining the expressions of the devils when they saw this difficult problem, Roger continued to talk about the last question: "This last question is a physics problem."

"physics?"

Saint Sarana and others' eyes were full of confusion: What is that?

"The so-called physics is actually a discipline that studies the real world." Roger scratched his chin and skipped the explanation of "physics". "And the third problem is the uncertainty principle established based on a physical constant called Planck's constant...."

"Assuming that the emission and absorption of electromagnetic waves are not continuous, but are carried out one by one, such energy is called energy nubs. Each energy nub is equal to hν, ν is the frequency of the radiated electromagnetic wave, and h is a constant, it is called Planck's constant. The uncertainty of particle position is the uncertainty of particle velocity x particle mass ≥ Planck's constant." Roger said calmly, completely ignoring the entanglement of Saint Sarana and others. "The third problem is to verify this uncertainty principle!"

The same is true. Roger does not think that anyone among the devils can understand physics and can have enough physics knowledge to verify this principle based on quantum mechanics.

Shaking her head, Saint Sarana's face turned as white as Desperate Knight Gero. She waved her hand to stop Roger from continuing and said weakly: "Okay, we already understand that these three questions of yours are not something that the devil can solve. Then use these three questions to set up magic seals."

Looking at the other people who also had a serious IQ on their face, Saint Sarana sighed and waved to Seraph Michael and said, "Everyone should summon their troops as fast as possible. The faster the better! We must counterattack Hell as soon as possible."

After saying that, Saint Sarana rode Saint Cizel away like she was running away. After the Desperate Knight Gero and others looked at Roger, they all left quickly.

It can be seen that everyone was afraid of the three difficult problems that Roger mentioned.

Prince Robin, who was full of tangled faces, shook his head, gave up and continued to think, and instead took Roger to the position of Princess Yekalina.

"I said! Brother-in-law! You should not go to such a dangerous mission to attack Hell, right?" Roger said to Prince Robin very seriously.

"No." Prince Robin smiled bitterly and shook his head, "You can see that even in the Dragon Knights, we were more or less rejected. In the coalition, the status of our elves was also very subtle. Except for the Nine Ring Tower and the Mercenary Kingdom, the rest of the forces also rejected our elves. Therefore, in order to ensure the future of the elves, I must not retreat in this battle."

"It's you, you don't need to take risks." Before Roger could speak, Prince Robin continued, "As the king of the Kingdom of Oaks, you really don't need to take risks."

"Brother-in-law, you have decided to go to hell, how can I back down?" Roger shook his head and said calmly, "And, only I can set the magic seal based on those three difficult problems."

When Prince Robin asked those three difficult questions, his face turned pale a little: "Okay, okay, don't ask those three questions again, really! I really hope I have never heard of those three questions..."

Looking at Prince Robin with a depressed look, Roger couldn't help but burst into laughter.
