The two of them walked from morning to afternoon, and were tired of walking and sat on the bench in the corner.

"Don't you buy nothing?" Lingzhu asked.

"I want to buy it too." Su Zhi put down the mineral water, "I don't have money."

"I can give it to you." Lingzhu said.

"No need." Su Zhi replied. He longed for soft rice, but after all, he was just talking.

"A big man is so petty for a little money." Lingzhu raised his legs and crossed his legs.

"Is it really a little money?" Su Zhi said, "and there is nothing that is sensible."

"I want to ask you." Su Zhi said, "Didn't you buy nothing?"

"I have bought what I want to buy a long time ago, why wait until now?" Lingzhu said. "Today I just came here to see if there is any new things I like, but unfortunately there isn't."

Su Zhi nodded with his lip.

"Your cultivation level in the later stage of Qi training..." Su Zhi remembered the elixirs they saw on the booth, which had the effect of Tongluo Pills to breathe and breathe, the Guzhen Pill helps consolidate spiritual energy, the Foundation Building Pill assists in building foundations, and the Purification Pill strengthens the foundation and cultivates the Yuan Pill. "Is it not good to buy some elixirs to increase the speed of practice?"

Lingzhu replied: "I prefer one step at a time."

"I don't think there is any problem." Su Zhi had learned about the effects of elixirs from Bai Suzhen and Xiaoqing. Pills can assist in cultivation. Except for a small number of elixirs that are eager to achieve success, most of them have no side effects.

The only problem now is that as the spiritual energy between heaven and earth becomes thinner, the chances of heavenly and earth treasures appearing are also lower, and the cost of refining elixirs is huge, so the elixirs are naturally expensive.

Su Zhixin thought that Lingzhu’s concept is similar to that of many people’s fitness concepts. It is definitely not recommended to use medicine to increase muscle mass. It is understandable that L-carnitine is not eaten. There is no need to fear protein powder.

He treated Lingzhu as a friend and wanted to correct her concept. He was about to speak when he heard Lingzhu add, "No need."

"What does it mean if you don't need it?" Su Zhi asked.

"I mean I can practice very quickly without the need for elixirs." Lingzhu said.

Su Zhi opened his mouth, but he wanted to speak but stopped. After thinking about it, it would be better not to talk too much.

After a while, the two of them continued to visit the expo.

I just walked past the booth of Pioneer Company and came to the booth of Aoba Bookshop.

Qingye Bookseller mainly sells books.

Su Zhi picked up a book with the title of "Changshui Jue", briefly flipped it and asked about the price, and immediately put it down after getting the price from the staff.

"This price..." Until the staff member walked away, Su Zhi couldn't help but complain. After all, there was no book that used tens of thousands of yuan as a unit. "I know that knowledge is priceless, but this is too expensive."

"You are wrong." Lingzhu said, "This is not a book, this is a secret."

"Secret books are also books." Su Zhi insisted.

"The secrets are not ordinary books," Lingzhu said. "These secrets are not printed, but written by the author with all his efforts."

Under the explanation of Lingzhu, Su Zhi finally knew what the secret book was.

The secrets are not products printed in the industry, but are all written by people. It is not because artificial things are expensive, but because the writer will write some of his own feelings when writing books. It takes a lot of time to write each book.

Such a secret book written by the writer who has given a lot of energy is easier to learn than a printed book. Readers can not only read the text in the book, but also read the writer's feelings, thinking and experience, and it is easier to learn the magical magic recorded in the secret book.

Of course, after reading such a secret book, after reading one person, those insights, thinking and experiences are read, it becomes an ordinary book.

There is another problem. The magical magic learned by reading secrets is easily influenced by the writer, which makes readers unable to walk out of their own path. However, as long as they continue to learn and use skills, it will sooner or later become their own things. Just delusions are just reading secrets, and in the end they can only learn a brief lesson.

"So that's it," Su Zhi nodded, "If this is the case, then the price will be understandable."

"The secrets here of Qingye Bookshop is more expensive," Lingzhu said. "If it is those individuals who sell secrets, it will be cheaper."

"Why?" Su Zhi asked.

"The secrets sold by Qingye Bookseller are guaranteed to be free of mistakes." Lingzhu said, "The secrets sold by individuals do not have this guarantee."

"If the person who wrote that secret book had a lot of mistakes in the magical magic, look at the secret book he wrote and read his feelings, thinking and experience. Even if he learned that magical magical magic at once, it might take a lot of time to correct the mistakes afterwards."

"I understand." Su Zhi laughed, "It's just to copy the answer when reading the secret bookstore. The secret book sold by Qingye Bookshop is guaranteed to be the correct answer. The secret book sold by individuals is likely to be the wrong answer. If you copy the answer and copy it into the wrong answer, it will be a lot of money."

"That's the reason."

The two of them walked around the booth and decided to go to the stall area to check it out.

The stall area is not as tall as the booth area. There is no booth that covers a huge area. At most, it is a small stall that often appears when traveling to the market in the countryside, with scattered things.

"Phoenix Pearl, don't miss it when you walk."

"The ancient god's remains."

"You can put down a truck's Sumeru mustard bag..."

"Call the mouse flute, call the snake flute..."

"Look at the demon mirror."

Su Zhi looked around and found a small stall with a broken secret book on it, and his heart moved.

Su Zhi walked to the front of the stall, picked up the secret book, and simply looked through it. It was more like a notebook for a student to teach class than a secret book.

The notebook is a notebook, the point is that the characters are really ugly, mainly because the characters are strange and strange, and the traditional characters are just fine. The strokes are horizontal and horizontal, and the strokes are not horizontal, and all strokes can be saved. It is like a word "参" is drawn with two circles connected, and a word "参" is drawn with a circle.

"Can you understand those words?" Lingzhu asked.

Su Zhi didn't say anything because he not only could understand it, but he felt that it was his words. Once he was anxious to write something without paying attention to strokes, he would write it like that. All of his textbooks were filled with those words.

The owner of the stall was a young Taoist. When he saw Su Zhi very interested, he was sitting behind the stall playing with his cell phone, so he quickly stood up.

"This is what I have found out from the pile of old books I have cleaned out from our Longhu Mountain Library Pavilion. It is said that it is the notes left by our Master Liu Yitian of Longhu Mountain when he was learning magic." The young Taoist said, "This is not a secret book he wrote specifically, but his wholehearted notes also left a little energy, so you can still read it."

Su Zhi held the notebook and breathed rapidly.

Lingzhu's hanging palm clenched into fists.
