Philosophy is a science among sciences, the highest collection of all sciences, and can guide the direction of human progress. Donglizi started directly from philosophy and understood its way. It was indeed an order of magnitude higher than Wu Sheng's starting point, and he completed it.
It seems to be faster, because there are only sixty characters in the heavenly book in total.
But Wu Sheng was miserable. He started from theorems of specific disciplines one after another. How many clouds would this cause? However, his mentality was very stable and he did not worry about it. He believed that his way of practice was more open.
, the composition of the worldview is more inclusive, no worse than Donglizi, and the prospects are more ambitious.
Dong Lizi's understanding of the gold in the sea cannot guide Wu Sheng. Specific issues still need to be analyzed in detail and hard to think about.
In this regard, Dong Lizi made a suggestion. He hoped that while Wu Sheng was comprehending the gold in the sea of heavenly scripts, he would give him the next heavenly script first and start both sides at the same time. This would save more time, but Wu Sheng refused.
.
Replace one with another. This is the fairest approach. No one should take advantage of anyone. When I understand Haizhongjin, we will replace the next one. This is Wu Sheng's simplest idea.
Therefore, Dong Lizi seemed more anxious than Wu Sheng. In the process of Wu Sheng's serious understanding, he took the initiative to think, plan in advance, actively make suggestions, and have the courage to take responsibility.
"After a point outside the straight line, there is and is only one straight line that intersects it! Do you think this is it?"
"Nonsense! How is that possible?"
"If there is a parallel, there will naturally be a crossover."
"Try it yourself..."
"Look...huh? It's true...there are many..."
Dong Lizi went into the forest to hit pine cones for a while, and then rushed back excitedly: "Try this again: after two points, there is only one straight line!"
"...This is a good one, but I have already understood it. Seniors can do it. They are very capable of self-learning. I give it a thumbs up!"
"Have you realized it? What do the words in this heavenly book look like?"
"That's right... Haha, I almost fell into your trap! I'll tell you after I understand your gold in the sea!"
Donglizi laughed and went to the woods to hunt pine cones again. When the evening came, he rushed back excitedly: "There is another one, the shortest straight line between two points!"
Wu Sheng stared at him for a long time: "Senior, are you involved in two points? But let me correct you, that's called a line segment."
"The thread is broken? Well, that makes sense. Cut it off at both ends. If it's broken, just cut it off. Do you think I understood it correctly?"
Wu Sheng pulled a piece of silk handkerchief in the alchemy room and marked two points. Dong Lizi connected them with his pen: "Look, a straight line...the broken line is the shortest. I have tried it.
Everyone has to circle around!"
Wu Sheng slowly folded the silk handkerchief and passed it through with a thin branch: "Is yours shorter or mine?"
Donglizi was stunned for a moment, holding his head and saying in pain: "How could this happen? I should have thought that this is an escape method. I have been thinking about it all afternoon, and I turned out to be wrong..."
Seeing how much pain he was in, Wu Sheng sympathized with him: "Actually, it's not wrong. The line segment between two points is the shortest. This is plane geometry. Well, it is true on the plane anyway. It is rare for seniors to think of this.
.”
Donglizi asked: "Is that right or wrong?"
Wu Sheng nodded: "That's right."
Dong Lizi urged: "Then try it, can you understand it?"
Wu Sheng said: "I have understood it a long time ago."
Dong Lizi's eyes flashed: "Little bastard, didn't you say that, well, your so-called friend only saw two words in the heavenly book? You are full of lies!"
Wu Sheng smiled and said: "It is true that I only saw two of my friends, but this junior also has another friend."
Although he did not get the next heavenly script, the old man's joy was beyond words - he was convinced that Wu Sheng had more than one heavenly script, because he believed that Wu Sheng must have many friends.
Seeing him running into the woods again, Wu Sheng chased after him: "Don't always think about two things, you can try three things!"
Dong Lizi turned around and asked: "What do you mean by three o'clock?"
Wu Sheng replied with a smile: "Senior, you can go to Nulu's house when you have free time. You will know when the time comes."
Just after saying this joke, I suddenly fell into deep thought.
Of course Donglizi did not go to Nulu, but he went to Qianshan and sneaked into a disciple's house without searching, and directly found a picture scroll on the disciple's desk.
Picture of a Lady with Hairpins, by the Master of Wantao Valley.
Wan Tao Valley Master is good at painting pictures of ladies, and the pictures he paints of ladies are very distinctive. For example, in this one, the famous hairpin flower has hairpin flowers, and only hairpin flowers.
After lying on this picture and studying it for half the night, the old man's back and legs ached. Then he returned to the back mountain manor and ran to Wu Sheng excitedly again: "I understand, I understand!"
Wu Sheng woke up from his deep thoughts: "What?"
Dong Lizi broke off a branch and drew on the ground: "Extend upward from each side of the triangle to form a triangular pillar!"
Dong Lizi said: "Isn't this a triangular pillar? Look, the two arms extend up from two points, and the back extends up from the lower point. Two people form a triangular pillar from these three points!"
Wu Sheng was stunned, then suddenly laughed, pointed at Donglizi and said: "It's okay, old man, but you really went there? Haha!"
Dong Lizi said angrily: "I didn't go, I found a picture and figured it out myself! Are you still laughing? Isn't this for your early enlightenment?"
Wu Sheng stopped laughing and said: "Yes, yes, it's my fault... Haha... This is called a triangular prism. Well, it's good to understand this, but it has nothing to do with the gold in the sea."
Dong Lizi asked: "How do you know it's irrelevant?"
Wu Sheng said: "I just realized this cloud pattern. Objects have three forms, gas, liquid and solid."
Regarding this avenue, Dong Lizi was very interested and asked Wu Sheng for a long time. He kept asking Wu Sheng until dawn.
It’s interesting. If we continue talking for three days and three nights, we won’t be able to finish it. Let’s talk about it later. Quickly, take out the second celestial script text that your friend saw!”
So Wu Sheng used his true energy to reveal a new cloud pattern: "Have you seen it before? Is it the same as what the predecessors have already understood?"
Donglizi was very excited: "No, no! New, new! Thirty-eighth! Come on, tell me, what's the truth?"
Wu Shengdao: "It's the theorem that my senior helped me verify before - the line segment between two points is the shortest."
Dong Lizi smiled and said: "No matter how you look at it, it has nothing to do with disconnection... It doesn't matter, keep filling in the blanks!"
Three days later, he filled in the Heavenly Book text into "Pingdimu". After understanding the Heavenly Book text, the old man's Yintang shone a little, and his energy and spirit increased. Wu Sheng was surprised when he saw this: "Senior, you are so spiritual
Does the Tao have the effect of rejuvenating youth?"
Dong Lizi said proudly: "As a side note, it's just a side note. Come on, I'll write another one, so hurry up!"
