These days, Li Chunfeng really can't hold back, he came to the small Taoist temple to find Gu Qing, when he first came to the palace, he was greeted by Wu Mei, Gu Qing was not in Sun Simiao, but in Sun Simiao, looking at Wu Mei's face, Li Chunfeng fell into contemplation again, many years ago, his master and Yuan Tiangang said that although this woman is a woman, she has the life of the emperor in her life, and she can be the son of heaven.

Looking at her face carefully, Li Chunfeng thought of Gu Qing's imperial appearance of the turmoil in the world, and this Gu Qing's fate steadily suppressed Wu Mei's fate.

"Li Chunfeng Dao Elder Gu Qing is no longer there, is there anything else?" Wu Mei saw Li Chunfeng standing in place.

From a distance, I saw Sun Simiao packing up the herbs in the Taoist temple, "Doctor Sun, I haven't seen you for a long time." ”

Sun Simiao straightened his old waist with difficulty, "Li Chunfeng!" ”

Li Chunfeng walked in the door, "It's been a few years since I left the house. ”

"Is Yuan Tiangang okay?" Sun Simiao asked.

"Master, it's been a few days since he died." Li Chunfeng said, "I came to Gu Qing today and saw that he was not there. ”

"That kid doesn't know where to go." Although he has nothing to do with Yuan Tiangang, he is also a little sad, "How did he go?" ”

"It's a good walk." Li Chunfeng said, "It's just that before leaving, he said that there would be big changes in the Tang Dynasty in a hundred years, at first the poor Dao thought it was Wu Mei, but after seeing Gu Qing, the lifeblood of the Tang Dynasty, the poor Dao became more and more incomprehensible." ”

"Count the heavens and the earth, count the fortune of people." Sun Simiao put down the herbs in his hand, "My disciple often said that fate is in his own hands, and it is never destined by heaven, and he also said that my fate is up to me." ”

"Gu Qing's life seems to be out of this world." Li Chunfeng's face was solemn.

"Poor Dao sometimes feels like he's from another world." Sun Simiao said.

Wu Mei cleaned the Broken Dao Temple, didn't hear what the two of them said, and hummed the song she had heard on her phone.

"Old man, girl, I'm back, do you have anything to eat, I'm so hungry."

Gu Qing's lazy voice came from the door, as soon as Wu Mei heard that Gu Qing wanted to eat, she came to the stove to prepare to boil the pot and cook, Cheng Chumo pulled people away as soon as she came, Gu Qing didn't even eat anything, thinking that the little girl had already included Cheng Chumo in the blacklist of guests.

"Gu Qing, do you know the old man." Li Chunfeng stroked his beard.

"I don't know!" Gu Qing raised his eyes and glanced at the other party, "Which one are you?" ”

"I was standing behind His Majesty in the palace, do you remember?" Li Chunfeng asked again.

"I don't remember!" Gu Qing tied the donkey and shouted inside, "Girl, put some pickles." ”

This guy didn't take himself seriously at all, and twitched the corner of his mouth vigorously, Li Chunfeng took a step forward, "Old man, it's Li Chunfeng!" ”

"Li Chunfeng?" Gu Qing suddenly realized, "Are you sick?" ”

"You're sick!" Li Chunfeng looked at the kid's behavior and was angry.

"You're not sick, what are you looking for my master." Gu Qing said.

Li Chunfeng's face gradually turned pale......

Gu Qing helped Sun Simiao pack up the herbs, "Master will rarely associate with this kind of person in the future, I heard that he seems to be crazy." ”

Li Chunfeng's face turned from white to blue......

"Master, look." Gu Qing pointed at Li Chunfeng's face, "His face is blue for a while and white for a while, and eighty percent is sick!" ”

"That's what you're mad at!" Li Chunfeng was about to leave as soon as he stomped his feet, and he couldn't talk to this person, it was simply a long life! Took two steps and stopped, what am I doing here?

Wu Mei warmed up the porridge and handed it to Gu Qing.

"Gu Qing, the old man asked you where you got the mystery of the multiplication formula." Li Chunfeng turned around and asked.

Swallowing the porridge in his mouth, Gu Qing took another bite of the steamed bun, "There was a math teacher who taught me in the past, and I don't know how he is now." ”

"Mathematics? Mathematics? Li Chunfeng became interested, "Where is your teacher?" ”

"In a place where you can't find it." Gu Qing smiled and ate the porridge, and said to Li Chunfeng, "This multiplication formula is simple, but it is even more difficult." ”

The multiplication formula table makes the number simpler, Li Chunfeng found that after having this multiplication formula table, more people will learn the knowledge of mathematics in the future, and he is a master of mathematics after seeing the entire Datang.

"The old man asks you again, what is more difficult than the multiplication formula." Li Chunfeng took another step forward.

"I won't tell you." Gu Qing sneered, handed the bowl in his hand to Wu Mei, and lay on the recliner and staggered.

"You!" Li Chunfeng shouted, "What an arrogant boy, if you have a multiplication formula, you will treat yourself as a math master?" The old man will come to meet you today. ”

"Girl, I'm a little thirsty." Gu Qing said.

Wu Mei knew that Gu Qing liked to drink tea after meals, so she put tea leaves in a bamboo cup and brewed them with hot water and handed them to Gu Qing, "The tea is going to be gone." ”

"It's okay, I've asked the monk to go pick tea leaves in the spring." Gu Qing said.

The cold wind blew Li Chunfeng's clothes, did this kid ignore himself......

"Gu Qing must not be rude." Sun Simiao saw that the atmosphere was not right.

Gu Qing, who was bored, drank tea and said to Li Chunfeng, "Actually, I respect you a lot, you are proficient in astronomy, calendrical calculations, Taoism, and you have written a push back map with Yuan Tiangang, your attainments are naturally not comparable, I have never regarded myself as a master of mathematics, and I have no heart to fight with you." ”

As soon as Li Tai arrived at the door of the Taoist temple, he heard the voice inside, Li Chunfeng is here?

"Don't have the heart to fight with the poor road? What do you mean by that cowdness? Li Chunfeng was aggressive and said, "You know how to count, and the old man asked you what six hundred and thirty-nine points of three is average." ”

Gu Qing just thought about it for a moment and said, "It's all two, one three."

Li Chunfeng was a little surprised and asked again, "How much is twice as much as seven thousand five hundred and four more two!" ”

Saying that, Gu Qing wrote and drew on the ground from one branch to the other, and replied after a while: "One hundred and fifty eighty-four!" ”

"This ......" Li Chunfeng didn't even figure it out himself, how could this kid be so fast, he had been calculating for a long time, and sure enough, it was one hundred and eighty-four, how did he calculate it, and his eyes wandered and noticed what Gu Qing wrote on the ground.

"What are you writing about?" Li Chunfeng couldn't read these strangely shaped words.

"It's called vertical." Gu Qing erased the numbers on the ground and rewrote the crooked words, "An algorithm of mathematics, in which the mystery is comparable to the multiplication formula. ”

"Vertical? When to use. Li Chunfeng stared at the ground.

"It's so cold, my toes are almost freezing." Gu Qing Gu talked about it left and right.

"Poor Dao asks you how to use this vertical form?" Li Chunfeng accentuated his tone.

Sun Simiao shook his head, "This kid taught those children to use the multiplication formula table and charged a penny, Li Chunfeng still forget it, this kid sees the money and opens his eyes, and he doesn't scatter eagles when he doesn't see rabbits." ”
