"What's wrong with you?" Li Qingniu looked at Zhou Jing, who came back from outside the door, a little strange, her face was ruddy, as if it could drip water, when she looked at Li Qingniu, her eyes were not as natural as before, and it seemed to be a little dodgy.

"It's nothing, oh, I suddenly remembered a joke related to the divination tower just now, so I couldn't help laughing," Zhou shrugged his shoulders and said.

"Oh." Li Qingniu agreed, and then continued to look down at the sketch in his hand, and after looking at it for a while, he asked Zhou Jing, who sat down next to him, "What did you just say should be added here?" ”

"Where?" Zhou Jingzhen leaned over and asked, after a few glances, she picked up a pencil and drew a few strokes on the sketch: "What do you think of it now?" Isn't it better looking and more atmospheric, and it can better highlight our traditional culture! ”

The first time he saw the sketch, Li Qingniu's eyes lit up, but after a while, he shook his head again: "It's good, but I always feel as if something is missing." ”

"What's missing?" Zhou Jingzhen looked down at the sketch, and nodded after a while: "It's something missing, if you look closely, it seems that there is a lack of mathematical beauty." ”

"Mathematically aesthetic?" Li Qingniu was stunned.

"Hmm." Zhou nodded in surprise.

Li Qingniu didn't know what the beauty of mathematics was, but he didn't plan to ask, that kind of thing was very profound when he heard it, it was better not to ask, he frowned and looked at the sketch carefully, and then recalled in his heart those memories passed on to him by the Angel of Doom, which seemed to have some information about the divination tower, and after a while, his eyes suddenly lit up, and he stretched out his hand to get a pencil: "I suddenly remembered an idea, how about you take a look?" ”

The moment he stretched out his hand, Zhou Jingzhen also happened to reach out to take the pencil: "I suddenly remembered an idea, how about you take a look?" She also said.

The hands of the two men touched at the pencil.

Both of them were stunned.

Then, both of them laughed.

"You speak first." Li Qingniu said, when he said this, Zhou Jingzhen also said: "You say it first." ”

Belch?

The two of them were stunned again.

"Okay, I'll do it first." Li Qingniu picked up the pencil and drew a stroke on the sketch.

"Hey, why are you exactly what I thought you were?" Zhou asked excitedly.

"You think so too?" Li Qingniu was also taken aback, the two of them were too smart.

"Well, that's what I really thought. You see, with the addition of these, the topological structure of this divination tower is close to perfect! Zhou said in surprise.

"What structure?" Li Qingniu was stunned when he heard it.

"Topology." Zhou was stunned.

"What is Topology?" Li Qingniu asked stunned.

"It's very simple, you see" Zhou Jingzhen took the pencil from Li Qingniu's hand, then turned over the piece of paper, and wrote on the back, explaining while writing, but after she said a few words, Li Qingniu was dizzy when he heard it, and he quickly interrupted: "Zhou Jingzhen, you mean that we should use this divination tower?" ”

Zhou Jing, who was interrupted from his train of thought, was stunned, and then quickly nodded and said, "Yes, you should use this, this is the most perfect." ”

"Okay, then it's decided, and we'll write such a sentence on the tower in the future, designer, Li Qingniu, Zhou Jingjing, what do you think?" Li Qingniu said.

"Okay. This will let the whole world know that the two of us designed this tower together. Zhou said with sparkling eyes.

"Maybe we'll go down in history because of this tower." Li Qingniu quipped.

"Maybe, with such a geometrically perfect tower, I don't believe it will ever be again in the world for at least a decade, unless we two design another one." Zhou was stunned.

Li Qingniu laughed, and said in his heart that you are really good at bragging.

Zhou Jingzhen also smiled, but he didn't say anything, but said secretly in his heart: "One day, you will know that I am excellent." ”

The two of them sat in silence for a while, each took a sip of water, and then Li Qingniu turned to look at her and said, "I"

At the same minute and second, Zhou Jingzhen also turned to look at him and said, "I"

"You speak first." Li Qingniu said.

"You speak first." Zhou Jingzhen also said in the same minute and second.

The two of them were stunned, and then laughed together.

"Let's talk about it this time." Li Qingniu said.

"Okay, I'll start with that." Zhou Jingzhen also smiled: "I'm afraid that this divination tower won't be repaired for a while, otherwise, you can help me divination first, don't wait for the divination tower." ”

"That's what I intended. If the divination tower wants to be built, it will take three or four months at the earliest. Li Qingniu also laughed.

"Looks like we're really in the know." Zhou was stunned.

"Huh?" Li Qingniu was stunned, and then laughed: "It seems to be true." ”

"And do you think it's worth celebrating?" Zhou asked suddenly.

"Celebrating?" Li Qingniu didn't know why.

"yes, I think we should celebrate." Zhou said with a smile, his smile was clear.

"Then celebrate, are you free today, I'll invite you to dinner." Li Qingniu said.

Zhou Jingzhen was actually free, but she shook her head: "I'm afraid I don't have time today, there are still some things in a while, or tomorrow?" ”

"Tomorrow? Well, then tomorrow. In this way, you come in the morning and I will help you with the divination first, and then we will eat together at noon, or you will come in the afternoon and we will eat together in the evening. Li Qingniu said.

"I'm free tomorrow night, but it's morning and afternoon," Zhou Jingzhen pretended to think, and after a while, she shrugged her shoulders apologetically: "There are arrangements for the morning and afternoon, or the day after tomorrow, let's have dinner together tomorrow night, and divination the day after tomorrow, how about it?" ”

"Yes, too." Li Qingniu said, in fact, the further he goes, he feels that the appointment is good, because his understanding and application of divination will be more perfect.

"Then it's decided." Zhou Zhen smiled: "Okay, don't bother you, I'll go back first." ”

"Let's have dinner together." Li Qingniu said.

"Thank you, but it's arranged for today." Zhou was stunned.

"Why are you so busy, as if you have a lot of opportunities?" Li Qingniu quipped.

"No way, I don't want to do that." Zhou Jingzhen smiled, then picked up the bag and waved his hand at Li Qingniu and said, "Then goodbye!" ”

"Goodbye." Li Qingniu also said, and then sent her out of the house.

It wasn't until she disappeared from sight that he turned around, and when he didn't want to turn around, he found that Xiaochan had been watching him quietly.

"What's wrong?" He asked.

"Not much." Xiaochan said, her expression calm, and then closed the door.
