A thousand enlightenments in one night, starting from being a menial apprentice.

Chapter 217: The Magic Account
Xiao Yu took the rather thick account book and sat down in front of the desk. It was not known whether he understood it or not, but he was flipping through the pages noisily.

After waiting for a long time, Xiao Yu became a little impatient. Huang Qing finally wiped the sweat from his forehead and handed an account book to Duan Rong.

Duan Rong took the account book, glanced at Huang Qing, and said, "Brother Huang Qing, I'm sorry to have troubled you."

Huang Qing was stunned for a moment and said, "Where? I'm too slow."

Duan Rong said, "I was inconsiderate. I just wanted to catch up with Brother Huang Qing. I didn't expect you might not be familiar with this document library."

Huang Qing felt relieved when he saw that Duan Rong was not angry at his slowness but explained to him sincerely.

Huang Qing smiled and said, "It's not bad. You should be able to get familiar with it after a few times."

Duan Rong took the account book and turned directly to the end, taking a look at the final balance of money in the account.

He raised his head, looked at Li Jun, and asked, "Isn't there a lot of money in the account? Why does Mr. Xu always say that there is no money in the account and delay paying the money?"

Xiao Yu and Huang Qing didn't understand what Duan Rong meant and looked at him in confusion.

But Li Jun suddenly felt very embarrassed. He gave an ugly smile and said, "I will go and pay you the money I owe to Escort Master Duan for the past few months."

Duan Rong smiled and said, "That's great!"

Not long after Li Jun went out, he brought back five silver bills and five receipts and asked Duan Rong to sign them one by one.

Duan Rong got his money back and was immediately in a good mood.

Xiao Yu looked at Duan Rong and asked, "Are you here to check the accounts or to collect the debts?"

Duan Rong glanced at Xiao Yu and said with a smile: "How about I give you ten taels?"

"Get lost!" Xiao Yumei glared at Duan Rong and lowered her head to look at her account book.

Duan Rong was fine, but Li Jun and Huang Qing on the side were a little dazed by Xiao Yu's angry look.

Duan Rong smiled indifferently and continued to look through the account book in his hand.

After many trials of life and death and baptism of killing, Duan Rong's temperament is no longer the same as when he first arrived in this world.

Duan Rong suddenly pointed to an item in the summary of one page and said, "Where is the detailed account book for this item? Let me see it."

Huang Qing looked at the item. He was familiar with its content, but there were so many account books in this room. Where could he find it?
Huang Qing looked at Li Jun again with a pleading look.

This time Li Jun simply ignored him.

Xiao Yu glanced over here, then turned to Li Jun and said, "I'm fine here for now. You're familiar with the document library, so go and help him find it."

Seeing Xiao Yu speak, Li Jun had no choice but to come over, look at Huang Qing, and say, "Come, come here! I'll teach you how to distribute the numbers of the books on the shelf."

There are still five days left, and Li Jun doesn't want to help Huang Qing look for it every day, so he might as well teach him how to find it.

Although there are many account books here, they are arranged according to a certain pattern. Huang Qing is an apprentice accountant after all, and he is already very familiar with various items. After Li Jun explained it once, he immediately understood. After a while, he found several detailed account books for the item that Duan Rong wanted and handed them to Duan Rong.

Duan Rong took the account book and just flipped through it casually, just for show. He didn't even think about checking the accounts carefully.

Xiao Yu had the same idea, and the two of them understood each other almost tacitly.

Duan Rong was flipping through the account book when he suddenly saw Li Jun, who was not far away, holding an abacus in his hand.

Duan Rong laughed and said, "Isn't Mr. Li Jun known as the best in mental arithmetic? Why does he always keep his abacus in his hand?"

Xiao Yu was a straightforward person, and she felt that it was even more tiring for her to pretend to look at the account book than escorting a convoy. She was just feeling bored, and suddenly she saw Duan Rong asking an interesting question, so she immediately raised her beautiful eyes and looked over curiously.

Li Jun originally didn't want to answer Duan Rong's question, but when he saw Xiao Yu raised her head and looked at him curiously with her beautiful eyes, his heart was suddenly moved.

Li Jun smiled immediately. Although he seemed to be looking at Duan Rong, his peripheral vision was always glancing at Xiao Yu. He said, "My mental arithmetic is number one, which means that my mental arithmetic speed and accuracy are the best in comparison. However, after a large number of verifications, the accuracy of mental arithmetic can never be compared with abacus arithmetic. Besides, long-term mental arithmetic is also very mentally exhausting. When the mental energy is exhausted, the speed and preparation will be reduced."

Duan Rong nodded. He had to admit that what Li Jun said made some sense.

After Li Jun finished speaking, he finally glanced at Xiao Yu. Seeing that Xiao Yu seemed very interested, he continued, "In fact, my mental arithmetic is just simulating abacus arithmetic in my brain. Therefore, my mental arithmetic method is also called abacus mental arithmetic or virtual mental arithmetic."

Xiao Yu was interested in the questions asked by Duan Rong. At this time, Li Jun began to say some boring terms, so she lowered her head to look at the account book again.

Li Jun couldn't help but sigh inwardly when he saw Xiao Yu had no reaction to his boasting.

Duan Rong's eyes suddenly flickered, and he said, "Mr. Li Jun, can I borrow your abacus to take a look?"

Li Jun hesitated for a moment, but still handed over his abacus and said, "I have had this copper abacus for more than ten years. My grandfather made it for me when I first learned to count."

Duan Rong was slightly surprised. Copper in this world is not cheap. He asked, "Mr. Li Jun also has a family background in this field, right?"

Upon hearing this, Li Jun said, "My family has been doing accounting for three generations."

While the two were talking, Duan Rong had already taken the abacus from Li Jun. The abacus was made of pure copper and felt cool to the touch.

Duan Rong looked at the copper abacus in his hand in the light.

This abacus is not very big. After all, copper is not cheap. Moreover, if a copper abacus is too big, it will be too heavy and it is not used as a weapon.

Under the mottled light, Duan Rong could see the copper abacus. The surface was polished to a shiny finish, but the inside of the abacus was covered with a layer of black verdigris. It was obvious that the abacus was very old.

Duan Rong looked at the abacus in front of him and suddenly said to himself, "Read the spirit of the instrument."

This thought flashed through Duan Rong's mind, and a set of data immediately appeared in front of him.

Object: Copper abacus

Spirit Level: Level 3

Devouring requirements: Host's mental strength level 3 (satisfied)

Devouring effect: Mastery of counting with chips, mastery of mental arithmetic, and mastery of ingenious accounts.

Duan Rong looked at the data in front of him and was surprised: Mastering three skills? This abacus turned out to be a third-level spirit tool.

Duan Rong's heart moved, staring at the three devouring effects, the last one was a wonderful account, thinking that with this devouring effect, he would probably be able to understand the account. After these few hours, Duan Rong felt that pretending to check the accounts seemed to be more tiring than really checking the accounts.

He then secretly said: "Swallow!"

Almost as soon as the word "devour" flashed through Duan Rong's mind, the data panel in front of Duan Rong shook and blurred, and then collapsed.

Duan Rong smiled, then handed the copper abacus back to Li Jun, and praised casually: "What a good thing!"

Afterwards, several people acted on their own in the dimly lit dark room.

Li Jun had already seen that Duan Rong and Xiao Yu were just pretending. They couldn't understand the account books at all. Moreover, when they reviewed the account books, they just flipped through them. They didn't take notes or check them. At least they flipped through several account books without even touching the abacus. What? Are they doing mental abacus like me?

However, Huang Qing was no longer so nervous. He was a smart person. As soon as Li Jun explained it, he understood the order in which the account books were classified. No matter what account Duan Rong asked him to find, he could find it quickly.
