Chapter 267 Pythagorean Theorem The two of them started chatting, and this almost became a natural thing. Gu Chan laughed strangely, sat down cross-legged, stared at Lao Bai and said with a grin, "Lao Bai, can you give me a simpler test? I'm really not good at playing chess, and it's pointless for us to waste time here, don't you think?" "Okay, then let's do the opposite. If you can come up with a question that stumps me, I'll consider you a pass." Lao Bai reached out and rubbed the white beard on his chin, saying with a confident look. Gu Chan stared at him as if he were a fool. Oh shit! She really wanted to say, did Fish Leong give you the courage? How can you say such big words? Lao Bai thought that he had frightened Gu Chan with his pretense, and said smugly, "Why, you don't have the confidence to scare me?" "No, I want to know, are you so knowledgeable? Aren't you afraid that others will stump you?" Gu Chan asked. "Hahaha……"
Lao Bai suddenly opened his mouth and laughed. After laughing for a while, he said proudly, "Do you know why I stay here?" "I don't know." Gu Chan spread his hands and said. "I have been unrivaled in scholarship since I was ten years old. At the age of twenty, I had already stepped half a foot into the realm of semi-immortality. From then on, I had no rivals, so I was lonely! I had no rivals in literature and martial arts, but my life was very boring. Therefore, after I turned forty, I came here and locked myself up here to live in seclusion." Lao Bai explained arrogantly. Gu Chan opened her mouth wide and was speechless. After all this time, it turns out that this seemingly skinny old man in front of me is actually a genius. He is both civil and military, but because he couldn't find an opponent and was too lonely, he chose to lock himself up and live in seclusion! No wonder no one in the world knows that there is such a powerful person with semi-immortal strength in the world. After understanding the situation, Gu Chan felt a sense of challenge. She took out a pen and paper from the bag on her waist, drew a triangle on the paper with a wave of her hand, and then marked the two sides with the numbers three and four to find the length of the third hypotenuse. If modern people saw this, they would definitely write the number five without thinking! After all, who hasn't learned the Pythagorean theorem in junior high school: the hypotenuse is three, the leg is four, the side is five? Isn't that something that can be easily learned? But this world is ancient! How could we know the Pythagorean theorem? So, when Gu Chan pushed the paper in front of Lao Bai, he was stunned on the spot, "What kind of question is this?" "Oh my god, aren't you invincible? You don't know such a simple math problem? Let me tell you, this is a triangle. The two sides are three and four years long respectively. I just want to ask you how long is the hypotenuse? Take your time to calculate it!" Gu Chan explained with a look of disgust. Lao Bai picked up the question paper with both hands, looked at it carefully, and immediately fell into deep thought. Gu Chan threw the pen in front of him, lay down on the ground, crossed her legs and hummed a song, thinking, if you hadn't been so boastful just now, I would have just given you a simpler problem like chickens and rabbits in the same cage. Since you have to be so boastful, then I'll show you the entire Pythagorean theorem. That's it! Don't you understand? Thinking this in her mind, Gu Chan didn't say much, she simply closed her eyes and fell into a deep sleep. Lao Bai picked up a pen and kept writing calculations on the ground, but no matter how he calculated, it was difficult to calculate the Pythagorean theorem with the mathematical knowledge of this ancient world. And most importantly, the length of the third hypotenuse of the triangle looked like five, but he had to calculate it to get this number! However, he couldn't calculate it, so he could only stand there and didn't know what to do. Time passed quickly, and three days passed in a blink of an eye. During these three days, the old man was already very frustrated by the question Gu Chan asked. He was originally very angry, but now he was exhausted and his white hair was messy. Gu Chan lay in front of him, propping her chin with her hands, and moved her legs back and forth, saying, "Lao Bai, why don't we just forget it? I'll just tell you the answer directly. You've been holding it in for three days, and I really can't stand it anymore. I really feel like I'm torturing you!" "How dare you, little brat, be so presumptuous in front of me?" Lao Bai said angrily.
"Okay, okay, okay, you continue to calculate, and I will continue to wait for you. I want to see how long you can keep being stubborn." Gu Chan said with a smile. Then she didn't want to stay there anymore, she immediately got up and went downstairs to play with the chimpanzee. Two days later, Gu Chan sang, danced and smoked drugs with the chimpanzee downstairs every day. They were living a very happy life. On the other hand, Lao Bai was almost driven crazy by this question. He was no longer as calm as before. He was so confused that he kept walking around the room on the second floor, but couldn't figure out the correct answer. That night, when Gu Chan went upstairs with a cigarette in her mouth, the old man was already lying on the ground, unwilling to move. He hadn't slept once in these five days and five nights, and was now exhausted. Gu Chan was startled, and hurried to the old man, helped him sit up, then put the medicinal cigarette to his lips and said, "Hurry up, take a puff, I guarantee you will feel refreshed and comfortable." "What is this?" Lao Bai asked curiously. "This is called medicinal smoke. I made it with herbs. Its main function is to refresh the mind." said Gu Chan. Old Bai took a deep puff of the medicinal cigarette out of curiosity. As the medicinal smoke entered his body, he, who was originally extremely exhausted, suddenly became as if he had been injected with chicken blood. His mind quickly became clear, and he was no longer as exhausted as before. Instead, he became more energetic. Then he reached out and grabbed the medicine cigarette, and continued to smoke it, saying as he exhaled smoke, "Not bad, this tastes much better than those old dry tobaccos." "Don't inhale so quickly, just the right amount." Gu Chan said with a smile. After hearing this, Lao Bai took another puff and then returned the remaining half of the medicinal cigarette to Gu Chan. Gu Chan put out the cigarette butt and put the remaining half of the medicine cigarette into the bag, then asked, "How about it, do you want to continue?" "Just tell me directly! How long is the hypotenuse? I'm too lazy to argue with you anymore." Lao Bai tried to save face and said in a bad mood. Gu Chan didn't waste any time. She picked up a pen and wrote down the calculation process clearly on the floor, and the final result was five. Lao Bai was stunned when he saw such a sophisticated calculation process on the ground. For so many years, he always thought that he was well-educated and no one in the world could compare to him, but now he finally understood that there are always people better than you. There is no doubt that the calculation process of the problem posed by Gu Chan has already surpassed the mathematical knowledge of this ancient world, which made him admire him very much!
