Luo Feng originally thought that with his eloquence, the stupid big man of the ghost clan who could be deceived in three or two sentences would become a cute and arrogant version of Princess Mononoke, and Cihang Jingzhai could add a cute general, I don't know how many future sons of the plane can be attracted to find her to generate electricity like a carp crossing the river.

But he never thought that the Heavenly Ghost Emperor stalked his neck and said arrogantly: "I am a dignified Heavenly Ghost Emperor, why do I need to hide my head and tail to hide my identity, the last time I was caught by mistake, I was on the Shushan faction, this time I just found the field, so that you human race can learn the true skills of this emperor!" ”

Embarrassingly taking the LM potion back, Luo Feng was also puzzled, but he didn't expect the invincible flickering Dafa to be repeatedly frustrated in this broken tower.

Demons are all tendons, they don't know how to seek advantages and avoid disadvantages, even if they threaten verbally and calculate the risks for them, they will not waver at all, and they will not give up if they do not hit the south wall.

flickered and failed, Luo Feng didn't insist, feeding the transformation medicine to the characters in the plot was originally a grass and a rabbit, if it can change, it will change, and if it can't be changed, forget it, there is no need to force it.

"Hehe......"

Luo Feng smiled to hide his embarrassment, and said: "Monks pay attention to fate, if you don't want to, this transaction will be treated as a poor monk." But before we said it, if you want to keep me safe in the tower, then you will stay on this level, if the Terran warriors rush in to find the poor monk, you have to keep your promise and stop them for the poor monk. ”

"Hmph, what's the point of worrying about trivial matters?"

The Heavenly Ghost Emperor snorted coldly and said: "The Lock Demon Tower is originally the emperor's territory, even if there is no agreement with you, if the human race outside dares to break in, the emperor will let them go and have no return!" ”

Although he didn't deceive the Heavenly Ghost Emperor into taking drugs to transform, releasing him from the altar was also quite profitable, and with his help, the copper door blocked by the rule force was easily opened.

At the same time, he got a free thug to help guard the third layer of the Lock Demon Tower, and stop those who disturbed him to go to the top floor to destroy the core sword pillar.

After entering the fourth layer of the bronze gate, Luo Feng and his party were separated from the Heavenly Ghost Emperor, and the Ghost King stayed on the third floor, one was to abide by the agreement to guard, and the other was to find Kong Phosphorus, a friend who had cheated him, to settle accounts.

Walking into the sealed bronze door, Luo Feng and his party came to a spacious hall, the hall was empty, and an old man with white hair and kind eyebrows was sitting cross-legged in the center of the hall, squinting and resting half-brightly and half-asleep.

Hearing footsteps at the door, the old man raised his head and said, "Reckless junior, don't go quickly, Hugh has to disturb the old man's reading!" ”

As he spoke, the old man grabbed a crutch beside him, the tip of the cane was aimed at Luo Feng a little, and an invisible energy broke through the air, this qi was invisible and silent, neither demonic nor fairy, it contained the power of Zhongzheng and peace, and the majesty of the righteous path.

Luo Feng hurriedly sealed and released the Buddha Gang shield, but the Buddha Gang didn't work, and was transmitted by the energy, and inadvertently hit Luo Feng's Buddha Dao Jin, making a crisp sound like a metal strike.

This energy has the strong inclusiveness of the sea and rivers, and the strong inclusiveness of virtue, it can be compatible with the power of the Buddha, and the Buddhist defense spell cannot resist it, but although the penetration is strong, the lethality is much worse, not to mention Luo Feng, who has cultivated the body of King Kong, even if an ordinary person is hit, he will not be injured if he stumbles.

Hearing the crisp sound, the old man let out a "huh", raised his head and squinted his faint old eyes to take a closer look, and said in surprise: "How can there be a monster in the lock demon tower who has cultivated the golden body of the Buddha?" No, it turned out to be a human being, and he was still a Buddhist monk. ”

"Amitabha, the old benefactor is also a compassionate demon, and his actions are very measured, a bit like a literati."

Luo Feng saluted him and smiled: "That trick uses a literary tone, right?" It is really rare for the body of a monster to cultivate the essence of a literati, but it is a pity that it is not pure enough, and the book is taken out to show off as soon as it is half-understood. ”

The old man was rude and said: "The junior is rude, the old man is a fairy in the book, there are thousands of books in his belly, he has been studying hard for thousands of years, carefully studying knowledge, he is the world's first university scholar, you dare to say that the old man does not seek to understand when he reads!" ”

"Tsk!"

Luo Feng pursed his lips and said with disdain: "Who gave you the courage to brag about your knowledge in front of the world's first doctor and monk, this is the so-called 'ignorant fearless', right?" It's also a coincidence, the poor monks are not talented, and the books in the world are all read, and there is no knowledge in the world that the poor monks don't understand. ”

The old man suddenly became energetic, and happily got up and said, "Okay, good, the old man has lived for thousands of years, and it is the first time I have seen a monk with such a big breath!" You monks do like to study knowledge, but compared to us Confucians, you are still far behind! A monk is holding an axe in front of the great Confucian, and I don't know who is ignorant and fearless! ”

When Luo Feng saw him take the bait, he was secretly happy in his heart, and said: "You have to set the rules first, and you have to set up a lottery if you win or lose." If you win, the poor monk will admit that Confucianism is higher than our Buddhism, and the disciples will respect you as a teacher. ”

The old man stroked his beard and laughed wildly: "How can the old man lose? Well, if the old man loses, he will also hold the disciple salute and respect you as a teacher! ”

Luo Feng laughed and said, "Very good, that's it!" There are more than 10 million kinds of knowledge in the world, what kind of category do you want to compare with poor monks? ”

The fairy in the book said proudly: "Your junior is only in his twenties, and the old man has learned thousands of years more than you, and you are not as good as me in any kind of knowledge!" Even if you compare Buddhism with you, the old man will win! ”

Luo Feng shook his head slowly and said: "The frog at the bottom of the well is nothing more than that, you are also a frog in the tower, your vision is not high, and your tone is not small." The poor monk doesn't want to compare Buddhism with you, that's bullying you, and the poor monk doesn't want to compare poetry and books with you, for fear of hitting you, so let's eliminate these two first. Let's choose from 'painting', 'piano', 'chess', 'miscellaneous', 'carpentry', 'mathematics', 'astronomy', 'geography', 'cooking' and 'Taoism'. ”

The immortal in the book nodded and said: "It's fair, first exclude the knowledge that you and I are best at, and only know whose knowledge is more extensive than that, this method of comparison is to ask me to answer first, and then I will ask you to answer, to see whose knowledge is profound!" The old man is old, don't deceive you for being young, let you ask first. ”

Luo Feng said: "Then I'll ask, this is a mathematical problem, please judge the old donor, 'Any single-connected, closed three-dimensional manifold must be the same as a three-dimensional sphere.' Is this statement true or false, and if so, how can it be proven? ”

The immortal in the book was stunned, he recognized every word in Luo Feng's mathematical geometry question, and he couldn't understand it at all.

"Junior, you're not bluffing the old man, are you?" The immortal in the book frowned and said: "Wouldn't it be a casual nonsense, insisting that this is a math problem?" ”

Luo Feng sighed and said, "You can't even understand the question, what else do you say is the best in the world?" Since your foundation is so poor, you can only give you a question in a less rigorous, but easy-to-understand way, which is easy to understand: 'In a three-dimensional space, if every closed curve can shrink to a point, then this space must be a three-dimensional sphere.' ’”

This time, the fairy in the book finally understood the question, the old man squatted down, took out a pen, wrote and drew on the ground, and closed his eyes and meditated, imagining the transformation of spatial graphics.

If you don't want to, after thinking deeply, the fairy in the book was surprised to find that this simple question, which seems to be able to be explained in one sentence, seems to hide an extremely profound mathematical truth, and it is really not something that can be figured out by using your brain and drawing pictures.

Luo Feng crossed his arms on the side to watch the excitement, this old goblin is not to mention an ancient scholar, even if he is a modern god of learning, let him study the "problem of the century" Poincaré conjecture that mathematicians all over the world took a hundred years to solve from scratch in a few minutes, and he will not be able to do it if he is tired to death.
