When night falls, the sky is full of stars.

Like a blue ribbon of Qinhuai River, it flows quietly in the center of Jiangning. The stars are scattered in the river, exuding a little starlight. It stretches all the way to the horizon and borders the stars in the sky.

On the river, the flower boats are still singing. Under the hazy lanterns, drunken men one by one, holding the delicate and enchanting woman in their arms, stepped into the flower legend, enjoying the warmth of the beauty.

The night was much deeper, and the weather was a little colder. Lu Heng walked by the river like this, looking at the quietly flowing Qinhuai River, as well as the flower boat play on the river like a dream. There is a vague feeling of being in the middle of a painting.

Thinking of Miss Wang's anxious appearance not long ago, Lu Heng felt a little funny.

At that time, when she said that she was willing to teach her own bookkeeping methods, Miss Wang was impatient to put on a posture and immediately wanted to learn.

And Manager Fang also nodded to Lu Heng with a smile, signaling that he didn't mind.

After that, the three of them set up a table in the eldest lady's room, spread out rice paper, and prepared pen, ink, paper, and inkstone. Under the appearance of Mr. Fang and Miss Wang, Lu Heng began the first class of modern mathematics in ancient times.

I have to admire Miss Wang's talent in mathematics, many formulas, Lu Heng just said it once, Miss Wang was able to understand it, and she also learned to draw inferences.

Then, Lu Heng stuffed the abacus formula in his memory to Miss Wang, and only breathed a sigh of relief when the other party was almost finished.

After drinking a cup of tea and looking out the window, he realized that it was late, and Lu Heng was about to leave.

Miss Wang took out a hundred taels of silver and was very determined to ask Lu Heng to accept it. said that it was Lu Heng's bonus for these two days.

Lu Heng did not refuse. He nodded and accepted it.

One hundred taels of silver is a bit heavy, and the current physical fitness is not very good. Although it is not a few miles from the palace to his own home. However, even for such a short journey, Lu Heng was also tired and out of breath.

Take a walk and stop for a while. Throwing his tired arm, Lu Heng secretly scolded himself in his heart for being useless.

It's useless to be a scholar, it seems that this sentence is really not a bunch of scholars with thin arms and legs!

Seeing the last light in the sky disappear, Lu Heng took a deep breath, gritted his teeth and carried the hundred taels of silver on his back, endured the pain of being burped on his shoulder, and walked towards home with one foot deep and one shallow foot.

……

In the palace, in the boudoir of the eldest lady of the East Cross Courtyard, the candle flame is flickering.

After Lu Heng said goodbye and left, Wang Tingzhi has been sitting there, with an abacus in front of her, and she has been practicing according to the mantra left by Lu Heng on the paper.

I have to say that Wang Tingzhi's mathematical talent is only a few hours. She integrated the abacus mantra that Lu Heng taught. At this time, the newly learned abacus mantra has begun to be used to calculate the accounts.

Crackling, the crisp sound of abacus beads, recalling in the boudoir.

The thick ledger is turned page by page. In a few moments, a thick ledger reached the last page.

Wang Tingzhi flicked her fingers, and after dividing the accounts by two. Closing the ledger, he breathed a sigh of relief, with a charming smile on his face: "It's really a lot easier!" His mantra is indeed extremely practical. And those weird formulas! ”

Wang Tingzhi moved the abacus away, poured herself a cup of tea, and after taking a sip, she suddenly thought of something that made this famous talented woman in Jiangning City show a sly smile on her face: "Using such a concise and capable abacus formula, as well as the fast-calculating arithmetic formula, I can complete an account book that originally took a day to calculate in a few hours as a beginner." Then Lu Gongzi, how could it take three days to finish counting those account books? ”

Wang Tingzhi's slender white fingers gently rubbed the teacup. In the white gas of fragrant tea, the sly smile on a beautiful face looked very suspicious.

……

Along the Qinhuai River, Lu Heng carried a heavy amount of silver on his back, and did not return to his home until the lights of thousands of homes were on.

also lost to Lu Heng's previous father-in-law, the governor of Jiangning City. Although there are some criminals in the entire Jiangning City, there are still very few things like robbing people and property. Otherwise, Lu Heng might have been robbed many times along the way.

Looking up, the dilapidated chaimen was already in sight. The humble lantern on top of the wooden door still hangs high, and the dim light is like a lighthouse in the night sea, faint but never extinguished.

On the cracked doorposts, all that remained of the faded couplets were a few mottled pieces of paper. The breeze blew, and the pieces of paper stuck to the pillar shook gently.

In the past seven days, every time he saw this dilapidated door and the old lantern hanging on the door, Lu Heng felt very quiet in his heart.

It's a quiet from the bottom of your heart, without the hustle and bustle, without the worries. There is just warmth and tranquility.

My sister-in-law would be very happy if she knew that she had earned a hundred taels of silver.

Lu Heng smiled in his heart and vigorously pulled the bag hanging on his shoulder. Grab the hoop from the door and gently pull it. There was a muffled sound from the heavy uh hoop.

After a while, a soft voice came from the courtyard: "Is it uncle?" ”

"It's me, sister-in-law!" Lu Heng stood at the door and responded.

The wooden door creaked open, and Liu Qingqing, who was wearing a linen coat, walked out of the door.

"Uncle, why did you come back!" Liu Qingqing tightened her coat, glanced at the sky, and asked.

Under the dim light, Liu Qingqing, whose hair is a little messy, looks like a lazy mature taste. She hooked her fingers and gently stroked the wind-blown hair in her ears, and her voice was as intoxicating as heaven.

Under the beautiful picture-like night, there stood a classical beauty who could only be seen in dreams in her previous life. This quiet and warm scene made Lu Heng a little intoxicated.

After not hearing Lu Heng's answer for a long time, Liu Qingqing glanced up, only to see that Lu Heng's eyes were fixed on him, and he seemed to be a little erratic.

Liu Qingqing's face turned cold, and the lazy color in her beautiful eyes disappeared.

He frowned, dropped a word, and turned and walked in.

"It's cold outside, uncle, let's go back to the house and rest!

Lu Heng, who came back to his senses, shook his head with a wry smile, carried the bag, and walked into the courtyard gate.

The cold wind blew through the night, rolling up patches of dry leaves. On the wooden door, the dim lantern fluttered in the wind, and the faint light flickered, but it was always bright.

The night of the third year of Da Zhou Qingyuan is still so quiet.
