Time is like water, and time is fleeting.

Unknowingly, Zhang Zheng has been living in the Weinan Courtyard for almost a month.

During this period, except for going back to Chang'an to see the old lady twice, he basically didn't move much.

It's amazing that as a famous gentleman in Chang'an, Zhang Zheng didn't go out to get into trouble this month.

For the people of Chang'an, it is really gratifying.

The reason is that Zhang Zheng is too busy during this time.

While busy planning the details of the academy, he was busy with the affairs of the printing house.

By the way, wait for the family's means to fight back against Li Shimin.

It's a pity that the family just didn't move, and Zhang Zheng was already impatient.

On the contrary, I don't know which day to start.

Since the first convoy carrying grain entered the official warehouse outside Chang'an.

Second, third...... There is an endless stream of convoys carrying grain.

Every day, the long convoy of grain on the official road outside the city has become a strange landscape outside Chang'an.

Every day, people from all over the world come to both sides of the official road to watch this unprecedented scene.

"When will I have to eat so much food?"

At the same time, Guanzhong, Henan, Shandong and other places are seriously affected by drought and slightly large-scale cities, all have a steady stream of grain into the warehouse.

Among them are rice from Jiangnan and wheat from the northwest.

The largest number of millet is planted on a large scale in the north.

……

The printing factory on the banks of the Wei River is already quite large, and it is busy every day.

Nearly 100,000 newspapers are printed every day from this novelty factory.

Half of them will be sold in Chang'an, while the other half will be sent by the Guogong Mansion to the big cities around Chang'an.

A week after the release of the Datang People's Daily, Zhang Zheng summoned Ma Zhou, Zhang Ergou and others.

The price of the newspaper was set at a penny.

And in the past, the way of distributing from small houses has also changed, and it has been changed to a fixed operation.

So at the gate of Chang'an's major square cities, there is an additional building called a newsstand.

The number of editors has also been upgraded from a shabby situation of only three people at the beginning to a scale of more than ten people today.

Talents, no matter where they go, are talents.

Today, the editorial team of more than ten people is faintly headed by Ma Zhou.

Zhang Ergou, who was originally in charge, has become a public relations figure who negotiates advertising cooperation with major businesses in Chang'an.

And did an excellent job, in just one month, not only did Zhang Zheng earn back the 1,000 yuan he invested.

In addition to the daily expenses of maintaining the printing house, there was a surplus of nearly 3,000 guan.

You know, it's only been a month.

Even Zhang Zheng was a little curious about how Zhang Ergou did it.

After careful questioning, I learned that some businesses in Chang'an almost fought in order to compete for the first place in advertising.

Zhang Ergou had an idea, it was not right to beat someone.

Since everyone wants this position, then use money to speak, whoever gives the highest price, that position will be given to whomever it is.

Zhang Zheng was overjoyed, but he didn't expect Zhang Ergou to comprehend the truth of the auction on his own.

Talents, for talents, what was not said, must be reused.

So Zhang Zheng praised Zhang Ergou fiercely in front of everyone in the printing house.

and rewarded Zhang Ergou with 100 yuan of money, a whole carriage of cash.

The factory suddenly fryed, and everyone was envious.

Zhang Zheng said that no matter who it is, as long as it is like Zhang Ergou.

If you can come up with a brilliant idea to generate income for the factory, there will also be such a reward.

The enthusiasm of hundreds of people in the factory has risen unprecedentedly, and everyone hopes that they can become the next Zhang Ergou.

The young men in Zhuangzi were led by Liu San and formed a patrol team of 100 people.

It was divided into three teams and patrolled day and night around the Zhangfu Courtyard and inside and outside the factory.

And the women, children, and children in the Zhuangzi, as long as they can help.

Zhang Zheng pulled his big hand and all went into the factory to do things.

Not only did he manage two meals a day, but he also had three eldest sons' copper coins as a reward.

Today's Zhuangzi has no one to do such useless work as carrying water from the Wei River to irrigate farmland.

The old man who was still squatting at the base of the wall basking in the sun gradually had a smile on his originally wooden face.

Although the time is very short, this small Zhuangzi is indeed different from when Zhang Zheng first came.

……

It is different from the harmony in the factory.

Zhang Zheng was scratching his ears and cheeks in the study of the other courtyard at this time, as if he had encountered something difficult to choose.

crumpled a drawing in front of him and threw it into the corner of the study.

Then he picked up a bracket in front of him that shone with a faint cold light, less than half a foot long, and scrutinized it repeatedly.

"What's wrong, what's wrong?"

Zhang Zheng was grabbing his hair and muttering to himself, and the scrapped drawings had been spread all over the study.

It turned out that Li Chengqian's birthday was approaching, and Zhang Zheng promised to give him a novelty.

So Zhang Zheng suddenly thought of the small sleeve arrows that he often played with his friends in later generations.

Of course, most of the sleeve arrows that I played with my friends in later generations were plastic.

In rural areas, bamboo is generally used as a raw material, which has no lethality.

However, now this thing is a birthday gift for Li Chengqian, of course, it is impossible to fool him with bamboo made of it.

So Zhang Zheng planned to restore the famous sleeve crossbow in history as it was.

Here's the problem, the range of the sleeve arrows made of fine iron is not as good as that of small toys made of bamboo.

The range of the sleeve crossbow made of fine iron is less than 20 paces, while the toy made of bamboo can shoot 30 paces away.

At first, Zhang Zheng thought it was a problem with the crossbow arrows, maybe the crossbow arrows were too heavy.

The spring made by Datang's technology can't shoot such a heavy arrow, so it continues to process and polish the crossbow arrow.

So much so that the current crossbow arrow is not so much an arrow as a long needle of the cold mangsen.

But what frustrated Zhang Zheng was that if he replaced the original crossbow arrow with a toy made of bamboo chips, he could shoot a distance of thirty paces away.

So Zhang Zheng began to look for the problem of springs again.

It wasn't until Zhang Zheng replaced the spring with a bamboo toy driven by sheep gut.

It was still shot thirty paces away.

Looking at the bracket that is similar to that made of bamboo, except for the different materials, the structure is exactly the same.

It's just that there is no problem with taking out everything alone, and there is a problem when it is combined.

So Zhang Zheng collapsed.

In my previous life, as an engineering student, it stands to reason that making such a small toy should be handy.

But God didn't let Zhang Zheng get his wish, but slapped him a few big ears.

"No, how can this be, what went wrong."

Zhang Zheng's eyes were blank, holding his head in both hands and shrunk on a few cases in the study, falling into deep self-doubt.

A moment later, the bolts were assembled again in a pile of parts.

Then he shot at the load-bearing pillar in the study, but unfortunately, the distance between the pillars was twenty paces away.

The bolt flew less than half the distance before falling to the floor with a "ding-dong" sound.

"It shouldn't be~"
