Chang'an City, in the steel workshop under Zheng An's name.

A little girl of seven or eight years old, wearing a small face towel, was pillowing her hands in front of a desk while burying her head in something.

The thin quill gently scratched her head, and the little girl frowned and thought, her eyes concentrated.

She has been working like this for days.

A lot of time is spent in Zheng An's workshop every day.

Zheng An was beside her, helped her make a cup of fragrant tea, handed it to the little girl slightly, and said with concern: "What's the matter, Xiao Yan, have you figured out a solution?" ”

"Don't bother me, let me study it again." Song Xiaoyan waved his hand and said, "If you overcome one more difficulty, you should be almost successful." ”

"Okay, then I won't bother you." Zheng An nodded in response, and really didn't bother Song Xiaoyan again.

Song Xiaoyan, who has learned the conservation of energy and the forging of rigid iron, and is extremely sensitive to numbers, is thinking about how to refine kerosene into gasoline.

The main thing is the refining tools in the book, which are not available in Datang at all.

And Song Xiaoyan also believes that Li Yi will never deceive her.

This forced her to find her own way to solve this problem.

Because this is the task given to her by Li Yi.

Just use the numbers and calculate them.

If it can really be calculated, it will naturally be accurate to a degree, and the craftsmen can make it according to the marks on it.

Song Xiaoyan felt that after these days of calculation, she had almost touched the edge of the threshold.

On the other side, a young man surnamed Yan was also frowning and thinking, constantly writing and drawing on the drawings, groping back and forth.

Zheng An smiled bitterly, came to the young man's side, and said loudly: "Tie Qing, how is it, do you have a clue?" ”

"I have a clue, but the structure of this place still needs me to calculate it carefully, otherwise the designed car may not be very safe." Yan Tieqing pointed to a certain place on the drawing, "I must eliminate this danger, otherwise, it will harm people's lives." ”

"......" Zheng An was speechless for a moment, and his face couldn't help but twitch.

Feelings you kid is here, secretly thinking about it for so many days, the other structures have already been calculated, but the danger is still being calculated here?

Zheng An always thought that Yan Tieqing hadn't come up with anything.

As a result, who knows, this guy has already calculated almost.

Yan Tieqing is Yan Lide's son.

Since he was a child, he has been around Yan Liben and Yan Lide, so he has long been aware of the design process.

Therefore, after receiving Li Yi's design drawing, he volunteered to take the task.

You know, he has designed several palace buildings one after another.

Even, even the design of the Tang Academy has his Yan Tieqing's stroke.

Therefore, Yan Tieqing is confident that he will be able to overcome this danger and successfully reduce the safety factor of the car to a minimum.

As for the tiny parts, as long as they are made according to his calculations, they should be able to be made.

Zheng An looked at it and knew that Yan Tieqing was dutiful to his work, so he didn't say much.

After all, if someone died because of the car, then the Zheng family's signboard would be smashed.

"Do the math, I trust you!" Zheng An encouraged, and he didn't stay any longer, but sighed and muttered in a low voice: "What kind of steel car does Gongzi make, isn't it very good to have a plate car?" ”

With that, he rode his bicycle and left the room to take a look at the workshop.

The construction of the bicycle is simple, so several have been designed for a long time.

Since it hasn't been sold yet, all the bicycles are kept in the workshop, so Zheng An also took them over and got over the addiction first.

After all, other bicycles are still in production.

Zheng An believes that in a short time, the bicycle given by Li Yi will definitely be popular all over the country, and it will be a good opportunity to make a lot of money.

Coming to the workshop and putting the bicycle aside, Zheng An walked to the workshop and asked the steward Uncle Zheng: "How is it Uncle Zheng, how is the wooden car built now?" Can it be tested? ”

Seeing this, Uncle Zheng, the steward, had a look of joy and a hint of worry on his face, and said in a deep voice: "Lang Jun, the old slave may not be able to say it now, only when it is assembled and let people try it." ”

"Done?" Zheng An was surprised, and his eyes couldn't help but light up.

Although he has always complained about Li Yi in his heart, he already has a bicycle, what kind of car do he want to build?

At the current level, where can you make such a big iron car!

However, hearing Uncle Zheng's words, Zheng An couldn't help but be excited in his heart.

"It's almost ready, Lang-kun." Uncle Zheng nodded, seeing Zheng An's face, and understanding Zheng An's inner excitement, so he pointed to a wooden car that was getting tires not far away, and said, "Wait for an hour, it should be able to be assembled, and the result will be known by then." ”

"Well, then let's wait and see, by the way, how is this car." Zheng An nodded, sat on the side and waited, rubbing his little hands together.

Cars!

The thing that's twice the size of a horse-drawn carriage and has doors and windows is a car?

These things have long subverted Zheng An's worldview.

But after getting used to it, Zheng An was also full of expectations.

In case the car is successfully developed, then he Zheng An is the world's No. 1 automobile factory, and the craftsmanship is all in his hands, which will definitely allow them to be the emperor of the Zheng family and directly defeat those families.

But at this moment, outside the workshop, a family member suddenly came.

At the same time, by the side of the Zheng family, a palace eunuch also followed.

"Lang Jun." The family shouted and quickly came to Zheng An's side, which made Zheng An come back to his senses, and as soon as he turned his head, he saw his own family Ding and Gao Gonggong.

"Father-in-law Gao? How did he get here? Zheng An was surprised in his heart, and immediately got up and walked towards Grandpa Gao.

Gao Gonggong was stuck in place, like a stone carving.

After seeing everything in the workshop, Gao Gonggong was dumbfounded, especially when he saw the wooden car being assembled and a bicycle next to him, he was completely stunned.

"This ...... Isn't this the car painted by Li Bo'an? ”

"Over there...... Bicycle? ”

"Oh my God, can you really make it?"

Grandpa Gao was surprised.

He originally thought that the things painted by Li Yi were just casually coaxing people to be happy, but who knew that there were really them!

And it's right in front of him!

"Father-in-law?" Zheng An shouted a few times, but seeing that Father-in-law Gao was still in a trance, he couldn't help but raise the decibels, and shouted again: "Father-in-law? ”

"Huh? Ah......" Gao Gonggong came back to his senses and looked at Zheng An, "What's the matter, Zheng Langjun?" ”

"......" The corners of Zheng An's mouth twitched, obviously you came to me, and asked me what's wrong?

Do you want to be so depressed?

Although he thought so in his heart, Zheng An was indescribably happy when he saw Gao Gonggong's soulless appearance.

After all, it was the first time for him, and he was as surprised as Grandpa Gao.

Thankfully, I'm used to it now.

After coughing dryly twice, Zheng An said with a smile, "Father-in-law, dare to ask you what is the matter when you come here?" ”

"Uh......" Gonggong Gao was obviously stunned for a moment, then he came back to his senses, remembered the purpose of his coming here, and reorganized his mind and said, "Lang Jun, the old slave was ordered by the Holy Lord to ask Lang Jun to bring two bicycles into the palace together. ”

“？？？” Bringing a bicycle into the palace?

How would the Holy One know?

Could it be that there is a spy in the family?

Or is it ...... Got the eyeliner that the Holy One planted?

Zheng An was a little stunned.

When Gonggong Gao saw this, he smiled and said loudly: "It's such a Lang Jun, the son said, you are producing bicycles here and building cars, so the saint ordered the old slave to invite Lang Jun and bring the bicycle into the palace." ”

Zheng An suddenly came over, "So that's the case." ”

Since it was Li Yi who said it, there is nothing wrong with it.

Anyway, their Zheng family, the emperor of the Tang Dynasty, has always relied on Li Shimin to eat, and they only need to hug Li Shimin's thighs.

And now, Li Shimin has an order, so it's good for him to bring one into the palace.

In this way, you can take the lead in stirring up a wave, and take the lead in letting those big families be suppressed from the momentum.

As for the price of the bike, that's already priced.

Zheng An also knows that the market must not be broken.

Otherwise, let's not say that Li Yi will not spare him, even if Li Shimin, the chief helmsman of the imperial businessman, will definitely not spare him, and when the time comes, he will lose the position of the imperial businessman, and the gain will outweigh the loss.

"Is Childe in the palace now?" Zheng An asked.

"In the palace." Gao Gonggong nodded.

"Okay, father-in-law, I'll ask you to wait a while, and I'll order someone to prepare and bring all the bicycles that have been built into the palace." Zheng An laughed.

"Lang Jun, please." Grandpa Gao smiled and waved his hand.

Zheng An was not verbose, and immediately ordered Uncle Zheng to push the built bicycles, a total of about ten, and came to Gonggong Gao.

"Then let's go." Zheng An got on a bicycle, "Father-in-law, do you want to ride one too?" ”

"Ahem..."Father-in-law Gao coughed dryly, saying that he didn't envy and didn't want to ride one, it was absolutely fake.

However, he has not yet guaranteed the safety of this bike, and he does not know how to use this thing.

So, Gonggong Gao shook his head in embarrassment, "Lang Jun, the old slave doesn't need it, and the old slave can't ride this bicycle..."

Seeing this, Zheng An didn't say much.

"Okay, father-in-law, you sit behind me, I'll take you!" Zheng An said with a smile.

"This ...... Is this good? Grandpa Gao's eyes were hot.

"Come on, father-in-law." Zheng An smiled and nodded, "The speed is still very fast, and it is much more comfortable than riding a horse." ”

"Uh...... Good. After hesitating for a long time, Gao Gonggong decisively chose Zhenxiang and sat behind Zheng An, trembling and frightened, and didn't know where to put his hands.

Uncle Zheng was guiding beside him, and Father-in-law Gao knew that he would hold Zheng An, or put his hands behind his back and hold on to the saddle of the bicycle.

Gao Gonggong decisively chose to grab the seat.

"Then let's go, father-in-law." With a soft shout, Zheng An stepped on the pedal, the bicycle started slowly, and he went out from the Zheng family's steel workshop and ran towards the street.

Seeing this, the rest of the family immediately got on their bicycles.

A vast procession appeared on the street of Suzaku Street.

In order to have a good experience, Zheng An drove a little fast, causing the father-in-law behind him to keep shouting: "Lang Jun, you slow down, you slow down...... I can't stand this old bone..."

"Don't worry, father-in-law, it's okay, it's safe." Zheng An was overjoyed, and kicked the pedal suddenly, "Hold on, father-in-law, let's rush..."

"Whoosh! Sou! Sou! ”

The wind kept rushing past Gao Gonggong's ears, so frightened that he hurriedly hugged Zheng An's waist.

Although he has kung fu, this thing is the first time to sit on this thing, and he is very worried.

With the appearance of a bicycle team, Yang Gongren on Suzaku Street was stunned for a moment, turned his head to look at Zheng An who was riding a bicycle, and was dumbfounded.

The rest of the people were also dumbfounded.

But the speed of the bicycle is not slow, not to mention, Zheng An is still driving with all his strength, and it didn't take long for him to disappear from Suzaku Street at the end and go in the direction of the palace.

After a long time, Yang Gongren came back to his senses and asked the guards beside him, "That's ...... What is it? ”

"Don't drive, it seems to be ...... Zheng Langjun and the high fathers..."The guards ate and ate.

"......" Yang Gongren couldn't help but twitch.

What the hell is wrong with these people?

What is it that just passed?

Could it be that Li Bo'an asked Zheng An, a guy, to secretly make up something new?

Yang Gongren knows that Li Yi has always cooperated with Zheng An.

And Zheng An is a Tang Dynasty emperor.

If this thing is not approved by Li Shimin, and there is no Li Yi to make suggestions in the back, Yang Gongren knows that he will not be able to think of it with Zheng An's head.

Therefore, he immediately ordered: "You bring the prisoners back, and this official will go to the palace!" ”

Throwing down this sentence, Yang Gongren got on the horse and drove away.

"I can't be late, or I won't have my share in this thing!"
