Li Chunfeng bowed and saluted and said: "Your Majesty, Qin Tianjian is very good, Poor Dao's lifelong pursuit of mathematics is now the period of breaking through the bottleneck, there are many smart people in this world who are more powerful than Poor Dao, and the road of learning has not yet been completed." ”

"Oh? Someone more powerful than Daochang Li. ”

Li Chunfeng smiled and said, "Your Majesty, wait for the poor Dao to achieve something and have better skills, and then come to serve Your Majesty." ”

After speaking, Li Chunfeng saluted again and turned to leave the Ganlu Palace.

Li Shimin held Li Chunfeng's resignation in his hand, his eyes flickered, and he asked Wang Ding, the old eunuch next to him, "Li Chunfeng, what's wrong?" ”

"Back to Your Majesty, Li Chunfeng has been to Jingyang before."

First, Li Gang went to Jingyang to resign, and now Li Chunfeng has also resigned when he goes to Jingyang.

The more I think about it, the more wrong it becomes.

"Jingyang? How is Jingyang again. Li Shimin was uncertain, and said to Wang Ding: "Go and find out, what Li Chunfeng has done in Jingyang." ”

"Whoa."

After speaking, Li Shimin took the tea sent by the process of biting gold, made himself a cup of tea, and drank it with enjoyment.

It was Cheng Biting Jin who made trouble, and it was Cheng Biting Jin who admitted his mistake.

Although Cheng Biting Jin is not a good person, in terms of admitting mistakes, Li Shimin is still very satisfied with Cheng Biting Jin.

After another sip, Li Shimin let out a long breath and continued to review the recital.

Walking out of the Ganlu Palace, Li Chunfeng said goodbye to Yuan Tiangang.

Looking at the huge Qin Tianjian, Li Chunfeng thought that it was time to say goodbye.

I learned a lot here, but the way of counting is far from the end.

After a few words of comfort to Yuan Tiangang, Li Chunfeng resolutely turned his head and left here.

Li Zheng is still in Jingyang, and spring is a good season for tinkering with perfume.

Seeing Li Chunfeng coming with a burden, Li Zheng asked, "Daoist Li, this is a long journey." ”

Li Chunfeng said: "Poor Dao figured it out? ”

"Got something figured out?"

"Poor Dao plans to live in your academy for a long time."

The movement in his hand stopped, and Li Zheng turned his head to look at Li Chunfeng, "Daochang Li, why?" ”

Li Chunfeng put down the burden in his hand and said: "Poor Dao, I have been removed from the position of Qin Tianjian and will be a teacher for the children in Jingyang in the future." ”

"Wait." Li Zheng said again: "I really want Daoist Li to teach the children mathematics, so if it is a long-term stay, the wages of teaching the children ......."

"It's not a matter of money or not, knowledge can't be measured by money, you just need to feed and shelter the poor."

Li Zheng was a little dumbfounded.

Li Chunfeng looked forward to him, as if he had found the true meaning of his lifelong pursuit.

It doesn't count as wages...... Li Zheng carefully calculated that the housing would be free, there were still a lot of empty houses in the village, and it was a big deal to live with Chu Suiliang and Shangguanyi.

I just don't know how much Li Chunfeng eats.

Li Zheng nodded and said, "I remember that there are spare empty houses in the academy. ”

Seeing that Li Zheng agreed, Li Chunfeng hurriedly saluted, "Thank you county marquis." ”

personally brought Li Chunfeng to the academy, and now the children have finished class.

In the academy, only Chu Suiliang, who was writing, looked at the Shangguan Yi of the White Snake.

Chu Suiliang knew Li Chunfeng, stood up and greeted him: "Daochang Li is coming to class again today?" ”

Li Chunfeng arched his hand and said: "In the future, you and I will be teachers here." ”

Assign the empty house of the academy to Li Chunfeng, "You can live here, the academy was only completed last year." ”

Li Chunfeng looked at this room and said, "It's good, it's very spacious, much more spacious than Qin Tianjian's room." ”

"Huh? Qin Tianjian shouldn't be worse than here. ”

"You don't know, Qin Tianjian doesn't look small, but most of the places are for Yuan Dao Chang, counting the stars, and the poor Dao lives in a small room."

Li Chunfeng looked around everything here and saw a more chic room, "What is this used for?" Strange chic. ”

"This is a latrine." Li Zheng said.

"Latrine?"

“……”

Li Chunfeng touched his nose embarrassedly, "I didn't expect your thatched toilets in Jingyang to be so chic, dare to ask where the thatched pit is?" ”

Li Zheng pointed to the toilet made of stone and wood, "This is the thatched pit." ”

Li Chunfeng observed the toilet, "This is a pit?" Why has the poor road never seen it? ”

"A new style of thatched pit." Li Zheng explained seriously.

"It's a poor road, and it's lonely and unheard."

Chu Suiliang introduced the usage to Li Chunfeng, pulling up a rope bolt, and water will be flushed into the toilet bowl and the excrement will be washed away.

There is a float in the water tank of the toilet, and after the water in the tank is flushed, there will be a large tank with a roof that flows into the small tank of the toilet through the bamboo tube, until the float in the small tank floats to a certain height, and the valve is pressed with water pressure when the water is full.

After listening to Chu Suiliang's introduction, Li Chunfeng said, "I didn't expect that a thatched pit is full of knowledge, and this trip to the poor road was not in vain." ”

Chu Suiliang also said: "After washing, it is as clean as new and has no peculiar smell. ”

Li Chunfeng said: "This thing is also made by the county marquis?" ”

Li Zheng looked at Li Chunfeng's expression, it seemed that he liked this toilet very much, and he was really afraid that this guy would live in the toilet without saying a word.

Li Chunfeng commented again, "The county marquis is full of talent, and it is indeed a bit wasteful to use it on the latrine, and it is really a luxury to wipe it with paper." ”

"It's called knowledge changing lives." Li Zheng thought to himself, I can use it wherever I like, the smelly thatched pit is really unbearable, for the sake of the health situation in the village, I have already built a new house last year.

The villagers are already using these toilets.

Li Chunfeng said again: "If you want to come to the palace, it's just like that, it's not as chic as this Jingyang." ”

"What's that, I don't know if the prince's goose was sent, it's really a matter of worrying about the intestines and going first." Li Zheng arched his hand and said, "You can continue to talk." ”

A few men around the toilet are commenting, and they always feel a little perverted.

Li Zheng left the academy and went on to work on perfume.

Although Li Chunfeng is a Taoist priest, although he is now resigning in Jingyang.

But it can't change that he has a heart to serve Li Shimin.

After knowing the magic of the flush toilet, Li Chunfeng immediately found the drawings for making the flush toilet in the academy.

He was sent to the palace.

Li Shimin was eating.

Wang Ding waited cautiously aside, and after having chili oil, His Majesty's appetite was much better.

Put a few of these on every dish.

You can now eat two bowls of a meal.

Taking the things handed over by the little eunuch beside him, Wang Ding glanced at it and handed it to Li Shimin, "Your Majesty, this is a piece sent by Daoist Li Chunfeng." ”

Li Shimin opened the piece and found that it was a drawing, looked at it curiously and said, "What is this drawing?" ”

Wang Ding pointed to the side of the drawing and said, "Your Majesty, it is written there." ”

Li Shimin's gaze followed, "Flush toilet? Built on top of a thatched pit......"

Suddenly realizing that something was wrong, Wang Ding knelt on the ground with a puff, "Your Majesty, the old slave is illiterate, he should be presented later, and he swept the Yaxing of His Majesty's meal, and the old slave is guilty." ”
