It has been half a month since Jin Se arrived at Xiaojin Mountain, she took Bie Xiao's blood, poured a small drop of the antidote she made into it, and the fifth child and the senior sister were nervously watching the changes in the blood beside her.

The blue-red blood immediately turned back to bright red, and Senior Sister and Lao Wu couldn't help crying happily. But Jin Se's expression became more serious, and she closed her eyes and counted down silently in her heart.

Three, two, one. Jin Se opened his eyes and looked at the blood in the bowl, and the blood, which was already bright red, slowly turned back to blue and red.

"How so?" Senior Sister frowned.

"Do you have to find that medicine?" Jin Se lowered his head and muttered to himself, "I've tried hundreds of recipes, but I can't replace this herb......"

"What herbs?" Senior Sister asked.

Jin Se pulled them a few steps away, and made sure that Bei Xiao couldn't hear before whispering.

"Furbisen." Jin Se raised his head and looked at the senior sister, "Fubi Immortal is a kind of flower, and the legend has been extinct for many years. When I was a child, I saw my master use it to detoxify a charlatan. I went back and looked through Master's books and saw the relevant records of this medicinal herb...... It was found that its medicinal effect was just right to cure the strange poison on the alliance leader. ”

"But where are you going to find Fubixian?" The fifth asked.

Jin Se shook his head heavily, "I don't know. ”

Don't lie on the bed and sit up with your body propped up. He looked like a normal person, except that his limbs were weak, and he was dizzy when he moved a little bigger. Jin Se watched him get up, and walked over in three or two steps to help him up.

"Don't bother!" Bei Xiao's face was pale, his voice was hoarse, and he shook off her hand and said, "I am self-inflicted, this is the heavens to accept me!" ”

"Nonsense!" Jin Se leaned Bie Xiao's shoulder close to him and said in a firm tone, "Don't worry, I will definitely heal you." I sure! ”

With that, Jin Se took a few steps back, walked to the senior sister's side, and asked her in a low voice, "Do you have any news of the miracle doctor?" ”

Senior Sister shook her head, and then asked, "Why did you think of asking him?" ”

"I think, maybe there is this medicine in the Holy Medicine Valley, and even if it doesn't, maybe we can find out the whereabouts of the medicinal herbs." Jin Se said, sighing lightly, "Now that this is the case, I can only mobilize the people in the door to find medicinal materials." ”

"We will also send more people to search for various places, and if there is any whereabouts of this medicinal herb, we will immediately inform the owner." Lao Wu walked over, and several people looked at each other and nodded.

Immediately afterwards, Jin Se hurriedly stepped on the road back to Qingchuan.

In the Nanwang Mansion in Kyoto, Ding Yuan sent the news of time for Qianwu.

"Lord Wang, Doctor He has a whereabouts." Ding Yuan came to his study with a letter in his hand, "This is a letter sent by Yu Yu from Qingchuan in Jiangnan, saying that it is the latest news from Qingchuan and the jade pot this year. ”

Qianwu stretched out his hand to take it, and frowned slightly after reading it, "When is it in Qingchuan?" What did he go to Qingchuan for? ”

After that, he carefully read the letter written by Yu Yu again, in which he learned the name "Jin Ruxu" for the first time, and learned that Ruxu helped control the flood of the jade pot, and the downstream of the jade pot had begun to open a canal.

Of course, that's all.

He still had a vague concept of the person "Jin Ruxu" in his heart, and he probably knew that he was a wise and shrewd businessman who did good deeds to help the world.

"You can help me get a message back to Yu Yu." Qianwu said to Ding Yuan, "I approved the request for appropriation to open the canal mentioned in his letter. Let him take 20% of the industrial assets and use them. ”

"Then do you want to inform Xiaojinshan's side of the news of the divine doctor?" Ding Yuan asked.

Sister Da waits for news every day.

"No, I want to figure out why he went to Qingchuan first." Qianwu narrowed his phoenix eyes.

Ding Yuan replied and retreated.

In a blink of an eye, it was almost the time of the Chinese New Year, and Su Rong, who had just rested for half a month, began to get busy again. The ripening of the chili peppers in the pepper field, plus the counting of the taxes to be paid for the farmers in the coming year, is simply a mess, one head and two big.

Su Rong was sitting at the table with the accounts in hand, and from time to time he reached out to the brazier to roast it. Ruxu hugged the peach blossom, seeing that his brows were about to be tied into a dead knot, he couldn't help but laugh, "Can you do it?" I think your head is on fire. ”

"It's not like this in any year, when it comes to the end of the recent years, it is the busiest time for Yulu and Senior Brother Rong." Jin Feng sat next to Ruxu and teased Peach Blossom, and glanced up at Su Rong.

Ruxu gave the peach blossom to Jin Feng, got up and walked to Su Rong's side, leaned down and looked at the account book in his hand. I don't know if I don't see it, but my brain hurts when I see it.

Countless additions and subtractions, small characters were added next to the accounts in and out, and there were remarks in the small characters, and there were deductions and omissions in the remarks, and the dense ants were huddled together.

"Tut-tut, keeping an account can be recorded like this, I really admire you from the bottom of my heart." Is this a ledger? Or scratch paper? Ruxu shook his head.

"Why don't you try?" Su Rong was busy picking out the abacus, and he didn't have a good breath when he heard her words.

"Then I'll try." As promised, the interface said.

Su Rong was stunned and looked up at her. Ruxu sat down, unhurriedly marked each item with a serial number, and then used Arabic numerals, plus multiplication and division under the serial number, to write out the entry and exit accounts, and then added or subtracted the number of remarks in the small print next to it. Then I listed the equation on the scratch paper and calculated it, and directly wrote the total amount of this item.

Su Rong was very annoyed when he saw that she had written a bunch of messy symbols, and he took the abacus and calculated it again, to his surprise, the total amount calculated by Xu was actually right, and it was not bad at all.

"How is this possible? You don't even use an abacus. Su Rong was stunned.

"How could it be?" Ruxu turned his head sideways and winked at him, "Do you want to learn?" ”

Su Rong looked serious and nodded.

If it was someone else, he might not believe it, but this person is Jin Ruxu! It's no one else, it's Jin Ruxu, who has earned more than 200,000 taels in half a year! How many advanced skills did she have in her head, how much knowledge did they never think of? Su Rong would not doubt her ability at all.

Then Su Rong called Yulu too, and the two of them held the account book and followed Ruxu to learn Arabic numerals for two days, and then learned addition, subtraction, multiplication and division, and calculated the amount. Ruxu saw that these two people's brains were better, and he also taught them the knowledge of decimal points.

About seven or eight days later, Su Rong and Yulu suddenly opened up, humming a little song every day to reconcile. After a few more days, the accounts were clear, and Su Rong was free to chat with Ruxu about arithmetic.

"Where did you get all this crooked thing?" Su Rong quipped.

"My master taught me." Ruxu smiled.

"Master? Which Master? Su Rong asked.

"You don't know ...... when you say it," Ru Xu said, "You reconcile accounts like this every year, isn't it really bad for your brain?" ”

As he spoke, Ruxu drew a table on the paper, "Look, this column is the name of the commodity, this is the unit price, this column is the quantity, this line says the total price, and there is a column of remarks at the back." ”

"Bookkeepers remember to be confused, and bookkeepers are even more confused, and some omissions in the middle are always inevitable. Wouldn't it be simple to unify the format of the ledger? Ruxu took a bite of the persimmon and said.

"You're saying we can use one ledger in one place?" Su Rong looked at the form drawn by Ruxu again, if it was filled in Arabic numerals, it would indeed be very convenient, but ......

"But you haven't touched this 'Arabic numeral' yet, and it's not convenient to fill it in with our words." Su Rong looked at Ruxu.

"If you don't have contact, you have to learn!" Xu glanced at him like an idiot, "Could it be that you want to put such a cumbersome account book for the rest of your life?" ”

"That's right." Su Rong thought for a while, "It's only been ten days since we learned this, and it's not difficult to teach other people." ”

Ruxu pinched another piece of pastry.

"That's it!" Su Rong patted her on the shoulder, and was so frightened by him that she choked on it, and quickly took a sip of tea.

"What's decided?" Ruxu patted his chest and asked slowly.

"In a few days, I'll call all the bookkeepers and let you teach for a few days." Su Rong smiled, "If they can all use it, let's try the method of unifying the ledger you said." ”

Ruxu shook his head with a smile and said, "I'm really lifting a stone to shoot myself in the foot, and I have nothing to do for myself." ”

Two days later, Su Rong really called the account office in the Guiling Sect's shop to come over, and after counting it, there were about 30 people.

She had no choice but to requisition Xikun's big house, let everyone move chairs to sit down, and made a wooden board to make a stand, and used paper instead of blackboard to start teaching mathematics to everyone.

At first, people didn't understand it and couldn't accept it. However, if you check the knowledge of the previous day every day, you will also assign homework, and if you can't answer the questions in class the next day, or if you don't do your homework well, you will have to deduct your salary. Su Rong was full of praise after hearing this, and felt that her approach was very wise.

"Wise?" Ru Xu crossed his arms and smiled, "This kind of exploitation and oppression operation of capitalists, didn't you force me to use it?" ”

If it weren't for Su Rong's explanation, she would definitely popularize this mathematics, and she wouldn't want to use this method to force everyone to learn this new thing.

After about ten days, the first batch of bookkeepers who mastered the third-grade mathematics successfully graduated, and they were assessed by the test papers, and those who failed continued to study for three days, and then took the second round of exams.

A few days later, Su Rong went to various shops to accept the results, and decided to start manufacturing new ledgers in large quantities according to the format as promised.

It's been a year of age, and the winter in the south has reached its biting peak. If you stay in the house all day, you don't want to go anywhere. She didn't feel cold when it snowed in Kyoto, but when she came to Kiyokawa, she hadn't seen a few rains since the beginning of winter, not to mention snow, but she was abused by the weather.

There are people in the house who are interested in this new mathematics, such as Xu Wo in the house, and he has nothing to do when he is idle anyway, so he opened another interest class. Although it is an interest class, the requirements are just as strict, and she requires everyone to meet their own standards.

Peach Blossom and Duan Yueze listened to it every day, and they both learned the ninety-nine multiplication table as they listened.

This may be the biggest harvest a few days ago, Ruxu touched the two cute heads and smiled with relief.
