People in Datang have been expelled from school

Chapter 279 The Difficulties of Feng Ang

The maid on the side quickly said: "Princess Changle has played with the Rubik's Cube before."

Li Shimin glanced around but did not see Li Lizhi's back, "Where is she?"

"Princess Changle went to Guozi to monitor Kong Yingda's lecture."

Li Shimin sat down again and held the Rubik's Cube that had been pieced together, feeling a little uncertain.

In the Guozijian, Li Lizhi put together the six sides of the Rubik's Cube in front of Kong Yingda.

Kong Yingda said doubtfully, "How did Her Royal Highness do it?"

Li Lizhi said in a low voice: "Actually, it's not difficult to find the pattern."

"Rules? What rules."

Li Lizhi added: "The Rubik's Cube is full of wisdom. If you solve it according to the rules, won't it lose its own meaning?"

Kong Yingda smiled and said, "The princess is right."

Li Shimin had been sitting in the Lizheng Hall reviewing the memorials, and when Li Lizhi came back, he asked, "Are you back?"

"Yeah." Li Lizhi nodded, and sat on the side obediently studying ink for Li Shimin.

Li Shimin put the Rubik's cube on the table in front of Li Lizhi, "How did you do it?"

"Li Zheng taught his daughter." Li Lizhi said aggrievedly again: "Father, don't worry, my daughter didn't go to see Li Zheng on purpose, but just took the young slave to see Li Zheng along the way."

Li Lizhi went out of the palace to see Li Zheng, and Li Shimin was no longer surprised by it, but thinking of his daughter turning to Li Zheng everywhere, Li Shimin felt inexplicably anxious.

Realizing that the atmosphere was not right, Empress Changsun came with brewing tea.

Li Shimin messed up the Rubik's Cube and put it on the table.

Knowing what her father meant, Li Lizhi picked up the Rubik's Cube and began to twist it, not very fast.

After Li Shimin drank a cup of tea, Li Lizhi also restored the Rubik's Cube.

Li Lizhi explained: "Actually, there are rules. Li Zheng said there are tricks, and the children in Jingyang Academy can play."

"Those children from Jingyang Academy?" Li Shimin knew that Li was teaching some children to read, but they were all ten-year-old children in the village of Jingyang County.

Li Lizhi nodded.

Li Shimin smiled coldly, "It's just some children's toys."

Li Lizhi smiled knowingly, and shuffled the Rubik's Cube in front of Li Shimin.

"..."

The Lizheng Hall was quiet for a while, but Li Shimin didn't pick up the Rubik's Cube, and said with a long breath: "The court has been arguing endlessly because of Feng An's matter, and I don't know if the Ministry of Education has any results."

Li Shimin stood up expressionlessly and walked out of the Lizheng Hall.

In the Ministry of Industry, Yan Liben has been studying Rubik's Cube and Huarong Tao these days.

Hua Rongdao had already untied it, and he was still turning the Rubik's Cube in his hand, until the last twist, the six sides of the Rubik's Cube were finally flattened together.

"So that's how it is." Yan Liben held the Rubik's Cube in his hand with an excited expression.

It took more than half a month to finally solve the Rubik's Cube and Hua Rongdao, and Yan Liben was so moved that he wanted to cry.

When I opened the door, I realized that I hadn't gone out for a long time.

Yan Liben ate a hearty meal, sat down again and began to study this Luban lock.

The Luban lock with 24 wooden strips interlocked is very strong.

Looking at Lu Bansuo Yan Liben in front of him, his expression became anxious again.

The little official at the side said to Yan Liben: "Master Yan, please rest for one night."

"No need." Yan Liben looked at the Luban lock intently, "If the old man can't break Li Zheng's Luban lock, how can I get a foothold in the Ministry of Industry, how can I be a great craftsman in the court."

"But you haven't had a good rest for several nights." The clerk said with a worried face: "You will burn your body like this."

Yan Liben drank a sip of strong tea to refresh himself, and stared at the Luban lock in front of him, "The Rubik's Cube and Huarong Tao have been solved, I don't believe that I can't solve this Luban lock."

Jingyang
The compound bow hanging on the wall still did not escape Li Chengqian's eyes.

Holding the bow, Li Chengqian said curiously: "This is the first time Gu has seen such a strange crossbow."

"This is actually not a crossbow, it's a clothes rack." Li Zheng tried to quibble.

"Really?" Li Chengqian said, "Then why is there still a quiver on the ground?"

"It's actually just a decoration, it's useless." Li Zheng argued again.

Li Chengqian took out an arrow, "I have long known that you, Li Zheng, are proficient in all kinds of crafts, and even Yan Liben is full of praise for your craftsmanship."

After talking about Li Chengqian, he had already raised his arrow, and said, "Gu grew up with those generals in the army since he was a child. Unlike Qingque, Qingque prefers to work with civil servants."

Li Chengqian aimed at a clay pot in the distance, shot an arrow, and the pot shattered.

"Huh? It's a strange feeling." Li Chengqian recalled the feeling when he drew the bow, and raised the arrow again.

This time, it aimed at a clay pot farther away, which was about three hundred steps away from Li Chengqian.

Another arrow was shot, and the sound of the bowstring was very clear.

Hit the target very accurately.

"His Royal Highness's arrow technique is really precise, I admire it."

Li Chengqian took out an arrow again, and said doubtfully, "Li Zheng, your bow is weird."

"It looks weird." Li Zheng shook the cattail fan in his hand and said, "Actually, the reason for the weirdness is caused by mechanics, which is also part of science."

"science?"

"That's right." Li Zheng looked at the scenery in the distance and said: "This bow uses a kind of mechanics and physics in science. Don't think this bow is strange, His Royal Highness. In fact, there is a lot of knowledge in it."

Li Chengqian raised his bow again, this time with all his strength, he shot the arrow.

The arrow flew straight over the stables and fell seven hundred paces away.

Li Chengqian held the compound bow in his hand and said, "Good bow!"

"That's natural. Science is all about exploration and verification. Using mechanics can make the bowstring and bow body exert the greatest effectiveness, shoot the farthest arrow with the least force, reduce vibration and increase stability, and greatly improve the hit rate."

Li Zheng went on to explain: "Actually, most of the arrows shot by ordinary longbows are vibrating, and the vibration of the bowstring is connected to the arrows. It often takes more force to hit the target."

"I know that you have a good way of collecting money and know all kinds of crafts." Li Chengqian said with emotion: "Sure enough, if a person is too free, he will do everything."

"Actually, I'm quite busy, um." Li Zheng nodded solemnly.

"You're too busy earning money and counting it."

Li Zheng touched his nose sheepishly, "We just talked about Lingnan."

Li Chengqian withdrew his eyes again, "You said you wanted Feng An to come to Chang'an, how do you invite the king into the urn?"

"Actually, the Lingnan area is not peaceful. There are many Tujia Hakka villages, and there are Nanzhao and Chenla on the border. In fact, Feng An's life is not easy."

Li Chengqian asked curiously: "You seem to know Lingnan very well."
