Luban lock is a children's toy, and the puzzle toy can exercise children's thinking.

Li Tai walked up the ridge in straw sandals, "The cane sugar has arrived, and it can be made into white sugar and sent to Luoyang in a few days." ”

followed in the footsteps of his brother-in-law and said again: "Is the Luban lock still there?" ”

Zhang Yang handed him the wooden strip in his hand, "Is His Royal Highness King Wei also interested in this toy?" ”

Li Tai sighed, "This king wants to try." ”

My father couldn't unlock Lu Ban's lock, and my brother-in-law often made my father unhappy.

Li Tai hurriedly came to the door of his father's summer residence, and put together this Luban lock, and after several attempts, a Luban lock slowly took shape.

This game is not difficult, it is comparable to the Rubik's Cube toy in my brother-in-law's house, and it tests people's calculation ability.

The wooden strips and the wooden strips were buckled together, and Li Tai frowned and combined, and he had already put together these wooden strips.

Think about it again, my brother-in-law's Luban lock structure is very ingenious, it's like building a house, and you have to build it around these pillars.

The heart said that the brother-in-law was so embarrassed by his father, and he didn't consider his father's embarrassment.

Li Tai sighed in his heart, the relationship between his brother-in-law and his father is like fire and water, and I still need to mediate it.

After splicing the Luban lock, Li Tai sat for a while and his father came back.

Li Shimin looked at this thing in Li Tai's hand, and was puzzled: "How did this thing get into your hands." ”

Li Tai hurriedly got up, "Erchen heard that his father was annoyed by this thing, so he took it and took a look, and it was already spliced." ”

Li Shimin took the Luban lock and looked at it, "You spliced it yourself?" ”

"Father, it's just a craftsman's thing, and the son thinks that as long as he understands the structure, it won't be difficult to unravel it."

Glancing at Li Tai, Li Shimin asked, "Has the recital of Zhongshu Province arrived?" ”

The guard in front of the door replied, "I just arrived. ”

No matter how delicate this Luban lock is, this is just a child's toy, and Li Shimin has little interest in it.

Walking into the courtyard, Li Shimin began to review the chapters.

The chapter was sent from Shuofang, and Li Ji led an army of 50,000 to attack for half a month, and finally arrived at Baidaochuan.

After the Baidao River is the boundary of Mobei.

He also wrote in the military newspaper about the wonderful use of the compass.

With this guide, the map of the Foreign Service House was used to make the march extremely fast.

Li Shimin put down the concerto, "Let the green finch come in." ”

Li Tai had been wandering in front of the mansion all the time, and when he heard that he was summoned, he hurriedly walked in, "Father." ”

Li Shimin frowned and said: "Yan Liben has been specializing in the compass of Lishan for a while recently, but he has not been involved in the mystery. ”

Li Tai explained: "The compass is not the same as Sinan, it is also simple, it has always been possible to march at night according to the stars, but during the day, the march will inevitably lose its direction and take the wrong road, with a compass to confirm the north-south direction will be twice the result with half the effort, especially in the desert where it is easy to get lost." ”

Li Shimin hesitated: "Is this thing difficult to cast?" ”

"At first, my brother-in-law was very troubled about casting this thing, and it was precisely because of this thing that the blacksmith workshop in Lishan cast the best iron materials, and the iron materials used were different from ordinary blacksmiths, and the magnetic materials involved were not easy to explain for a while."

When he led his troops to fight and gallop through the Central Plains, Li Shimin naturally saw many masters who could pinch and calculate, and the speed of the march could determine the victory or defeat of a war.

has a deep understanding of this, and Li Shimin is sure in his heart that Zhang Yang, this kid, must still have a lot of good things in his stomach that has not been spit out.

Sure enough, he was going to save his life first! When his use value is gone, hang him in front of the Chengtian Gate.

Nodding with satisfaction, Li Shimin smiled and said, "You can step down." ”

"Whoa." Li Tai bowed and saluted, and couldn't help but feel a little uneasy in his heart, why was his father's smile so penetrating.

At the same time, Zhang Yang also looked at the dossier sent by the Foreign Affairs Yuan, and the mutual market in the Hexi Corridor was also ready, and he was still vacillating in the selection of candidates.

Picking up the pen, Zhang Yang wrote down the corresponding arrangement, asking Di Zhixon to take a trip to the Hexi Corridor, and the Foreign Affairs Yuan presided over the mutual market arrangement.

Looking at another file, this is the situation in Liaodong, Da'an sent people to find the king of Goguryeo, and after some lobbying, he finally asked Goguryeo to escort the Japanese people back through Goguryeo.

Shuofang's soldiers and horses had already crossed the Baidao River.

Li Yue on the side was looking at the story that her husband had just written down in her hand.

"The story of the eunuch is indeed twists and turns." After reading it, Li Yue commented: "How about letting our printing workshop print this volume of stories? ”

Looking at her daughter-in-law's expression, she felt that since the establishment of the printing shop, the profits have been weak, and today's profits have almost stagnated.

"The husband wrote before that the Red Chamber and Liang Zhu were both rejected by the scholars, and this story will cause a lot of criticism in the community."

At that time, teacher Pu Songling wrote the story of Liaozhai according to the strange news passed on by people's word of mouth.

There are also many stories that are full of irony.

Li Yue whispered: "The Red Mansion was abandoned by the scholars, but our Red Mansion is widely spread and circulated by many people. ”

"Justice cannot be killed." Zhang Yang nodded.

"Yes, you can't kill it."

The husband and wife share the same hatred for this.

From the beginning of the war at the end of the Han Dynasty, the reputation of the five surnames and seven hopes has long been not as good as it was back then, when people have been oppressed by the scholars for a long time, there is already a sense of resistance in their hearts.

The evil act of monopolizing the career is clearly exposed.

I don't know when these gate valve clans have stopped installing.

They are the passage of people to the official career, if you don't bow your head to the family, even if you have the best talent, your talent is useless after all.

The future of a lifetime is in the hands of the big family, and the family lasts for hundreds of years, a dynasty may be two or three hundred years, and the family can last for nearly a thousand years.

Looking at the past, individuals and small forces could not compete with the family, and there was the opposition between Yang Guang and the five surnames back then.

And now there is Li Shimin's struggle, and the imperial examination has been held year after year.

Some justice should also wake up, this world is no longer what it was back then, years of war, and the family is not as strong as it was at the beginning.

I don't want Datang's hard work to become the soil for the family to grow again.

This is the best chance to bring down the Maison.

It is also the best time to awaken the spirit of resistance.

The most powerful weapon in this world is thousands of ordinary people, the power of the masses is huge, as long as the justice in their hearts is awakened, tens of millions of people chant together.

With the court to rely on, as long as Tian Khan can always stand on the side of the masses, he can gain unprecedented strength.

This force can overturn the heavens and the earth, and it is easy to overthrow the family.

At night, Li Yue copied down the story of the eunuch and handed it to Aunt Yang, "Trouble Aunt will hand it over to the printing house tomorrow and let them start printing these stories." ”

Auntie smiled and nodded.

Li Yue spread out the test paper, and then grinded it to prepare, she smiled softly, "My husband said that there are many moving stories in Liaozhai. ”

Zhang Yang held his toolbox and nodded.

"I have prepared pen, ink, paper, and inkstone for my husband." Li Yue's eyes were full of anticipation.

Zhang Yang glanced at the paper and pen and ink on the table, "I don't want to write now." ”

Li Yue's smile froze on his face, "Why?" ”

"I still have to perfect the primer of the soil mines."

"But ......"

Zhang Yang interrupted her, "It's not early, you rest first, I'm very busy." ”

Li Yue stopped in front of her husband's workbench, "If my husband doesn't write, I won't sleep." ”

Zhang Yang took a deep breath, "If you don't sleep, help me grind saltpeter and charcoal well." ”

After being stunned for a long time, Li Yuehao gritted his teeth and strode back to his room and threw the door hard.

The sound of the door closing was so loud that the children in the bedroom were scared to tears.

Xiao Wu frowned and said, "Teacher, what's wrong?" ”

Zhang Yang sighed: "Your teacher is in a bad mood today and has lost his temper. ”

Xu Hui came up and whispered: "There are often quarrels between husband and wife, and my father and mother would quarrel with each other because of a trivial matter. ”

Listening to this little girl's story, Zhang Yang was shocked in his heart that there was still such gossip to listen to.

Unexpectedly, Xu Xiaode is also afraid of his wife.

Zhang Yang covered his mouth and nose and grinded gunpowder, and Xiao Wu and Xu Hui finished the homework assigned by the teacher today.

They sat in the courtyard, and under the starry sky, two girls played chess against each other.

The bear lay lazily on the side, yawning boredly.

The princesses and princes also came to Lishan to escape the summer, they are a group of children with fine clothes and fine food, and the little bear also enjoyed the blessings, eating and drinking are all dried meat and big peaches from the south, and even a bear has ice cubes to chew.

Life is very beautiful, and now it is getting stronger and stronger, and I am not afraid of the torture of this group of bear children, at least it will not do any harm to it.

Xiao Wu and Xu Hui played a game of chess, and after washing, he said, "Master should also rest early." ”

Zhang Yang nodded and said, "You guys go to sleep first." ”

Put the ground gunpowder in an iron basin, Zhang Yang picked up a wooden stick and burned it on the oil lamp, and the wooden stick was lit and slowly approached the gunpowder.

The flame met a little gunpowder and immediately ignited.

There was another puff of white smoke and the pungent smell of gunsmoke.

Zhang Yang tossed so badly that he waved his hand to disperse the white smoke in front of him, and opened the window to let the night breeze blow in.

When the combustion is over, look at the situation of the gunpowder, and then look at the gunpowder, the combustion is quite sufficient.

Take a few more parts from the workbench and go to the yard.

Put gunpowder in the center of the iron plate, then take a heavy object and place it on the iron plate, and install the spring.

When I pressed it hard, I released it again, and there was a crisp sound when the iron pestle met the iron plate, and the gunpowder inside began to burn.

Zhang Yang recorded the experiment record and continued to prepare according to the previous process.

It was repeated several times to compare the reaction time of gunpowder.

The density of the gunpowder inside at the moment of detonation is important.

Zhang Yang looked at the drawings worriedly, and the volume of the soil mine should be as small as possible in order to improve the sensitivity of detonation.

After setting a few directions for improvement, Zhang Yang found that the smell of gunpowder on his body was disgusted even when he smelled it.

After washing it with cold water, and repeatedly sniffing it to confirm that there was no smell of gunsmoke on his body, Zhang Yang changed his clothes, and then wrote down a few improvement plans, and then planned to rest after preparing these.

I was about to push the door to go to the bedroom to sleep, but I pushed it and found that the door was locked.

Zhang Yang knocked on the door and said, "Daughter-in-law, open the door." ”

"No!"

Li Yue responded decisively from inside the house.

Zhang Yang leaned against the door, "I am busy improving the soil mine for our future self-preservation." ”

"I slept."

Li Yue's words came from the room again.

Zhang Yang pushed hard again, in fact, the door was not firm, and he could push the door open with a deep breath and a push.

But push open the door, and the door will be gone.

My own door, I feel distressed.

Zhang Yang stroked the heart of the door and said that he didn't care about it for now, took out the futon from another room, and spent the night on the table.

When he woke up the next day, Zhang Yang found that his daughter-in-law had woken up early, and she was in a good mood cleaning the yard with a broom.

Li Lizhen came early in the morning, "Huh? Does brother-in-law sleep outside the house? ”

Zhang Yang nodded and said, "Your imperial sister was angry last night. ”

Helping her brother-in-law clean up the bedding, Li Lizhi whispered, "Is it that my brother-in-law has done something bad?" ”

Zhang Yang poured a mouthful of cold water and rinsed his mouth, "Your brother-in-law and I are a good person, how can I do bad things." ”

Li Lizhi smiled and went to find her imperial sister again.

Zhang Yang brushed his teeth briefly and walked out of the room with the drawings.

All the parts are drawn on these drawings, and they are all broken up.

Even if they were to make it, they wouldn't know what it was used for.

Zhang Yang walked all the way to the other side of Lishan, where many villagers were busy, the factories in the village were all moving here, and Shangguanyi was also arranging manpower here.

"County Marquis, why are you here?" Shangguan Yi was busy drinking tea.

"Where's Master Jiang?"

Shangguan Yi pointed to the location of the blacksmith's workshop, where Master Jiang was holding a bowl and sitting alone under a tree eating food.

Zhang Yang nodded when he heard this, "Thank you for your hard work." ”

Shangguan Yi sighed, "It's okay, the villagers are really hard." ”

"Our factory has been expanded, the production efficiency has improved, and they are given money for processing."

"Then the lower official will thank the county marquis for the villagers."

"You're welcome, I haven't asked you all this time, what is the situation in Lantian County."

Except for Lishan, the entire Lantian County is a fief of the daughter-in-law, and there is a large population there.

Shangguan Yi explained: "Lantian County is building our new home, using 2,000 people, which should be arranged by the Guogong. ”

Lantian County is not like Lishan.

Lishan was built by itself, and Lantian County, with its large population, has just started construction.

The renovation plan in Lantian County started very slowly, and it was also necessary to consider the long-term peace and stability of the county, unlike the villagers of Lishan who could trust them in every way.

"In the future, we will have to consider more for the benefit of the villagers, and we in Lishan will also pull Lantian County to get rich together."

"That's what the county marquis said."

patted him on the shoulder to show sincerity and dependence, and then Zhang Yang walked towards Master Jiang.

Master Jiang was eating a bowl of rice porridge and holding a cake in his hand, and when he saw Zhang Yang coming, he took out a hot naan cake from his arms, "Child, you haven't eaten it yet." ”

He smiled and took the cake handed by Master Jiang, and also sat in the shade of the tree, eating the cake in one bite.

"Didn't sleep well last night?" Master Jiang noticed Zhang Yang's complexion, "Could it be that His Royal Highness the King of Wei did not do a good job and was punished?" ”

Zhang Yang chewed the cake in his mouth and shook his head, "That's not it, I had a falling out with my daughter-in-law last night." ”

Master Jiang smiled, "This is how it is between husband and wife, it is inevitable." ”
