Back to Cheng's mansion, before Cheng Yaojin and his two sons could tell the good news.

Xuanzhi's servant came to Cheng's mansion.

"The imperial decree has arrived, and the members of the Cheng family are waiting to receive the decree."

Cheng Yaojin immediately led his wife back to his children and knelt down to accept the order.

"Chengfu Linghua, kind-hearted, virtuous and virtuous..."

"It is really admirable to raise King Ai and King Woo in a foreign country."

"I, I am grateful for Linghua's outstanding contribution to the Cheng family and to the Tang Dynasty, and make Linghua the wife of Zheng Yipin."

"..."

"My lord, thank you for your majesty's grace."

Cheng Yaojin respectfully accepted the imperial decree.

An imperial decree changed the status of Linghua.

At the same time, let the coal and the carbon, the two brothers, cry bitterly.

They never dreamed that this would be the result.

His Majesty even decreed to reward his mother as a first-class imperial wife.

Thinking of my father going with His Majesty after his downfall.

The two brothers thought it was because their father begged for their mother from His Majesty.

My gratitude to my father is immeasurable.

Today's Cheng Mansion is extremely lively.

Mrs. Sun brought the whole family of the Lin family here.

Cheng Yaojin, Mrs. Su Guo, and the two princesses Changle and Jinyang also came.

Don't dare to neglect now.

See you now.

Relatives belong to relatives.

Etiquette belongs to etiquette.

The more you reach their high position, the less you dare to be sloppy.

Just when everyone was about to take their seats.

The servant's voice sounded outside the mansion.

"His Royal Highness and the Crown Princess have arrived..."

Woo la la, a large group of people quickly came to the yard immediately.

"Minister, see His Highness the Crown Prince, see the Crown Princess."

Cheng Yaojin and Mrs. Su Guo rushed to pay respects.

"Uncle, aunt. Hurry up and get up."

"Guoguo just heard from Zhinu that his uncle and aunt have returned, and they brought back two older brothers. Guoguo hasn't seen his uncle and aunt for a year, and he misses them very much."

"Send the gift to the back room."

Guoguo gave instructions to the servants and maids behind her.

"I am so grateful to be cared by the Crown Princess."

"It's okay, it's my family here, don't mess with it, it will make Guoguo feel bad."

Sun's words made everyone laugh.

"Uncle, aunt. Mother is right."

"Guoguo is still the same Guoguo as before, there should be no barriers between us as a family."

The craftsmen of the Ministry of Industry finally finished making all the molds.

After cooling down, it was handed over to Li Tai.

After Li Tai surveyed one by one joyfully, he asked the craftsman to put them on the carriage.

After getting into the carriage, Li Tai went straight to the design institute.

Lin Ran has already cooked the meal, waiting for Qingque's return.

"Teacher, take a look at this steel casting mold, is it qualified?"

"Qingque has already checked."

Lin Ran inspected the molds that Shouren and Yuan Tiangang brought over after hearing the words.

"Yes, after dinner, let's start assembling."

The five happily had lunch.

It started to assemble.

"The blue sparrow is exactly the same as the wooden structure, you can start to do it, the teacher will watch on the spot."

Hearing Lin Ran's order, Li Tai, Yuan Tiangang, and Mo Shouren acted immediately.

Lin Ran and Li Chunfeng became the audience.

This tossing is an afternoon.

After all, it was the first time the trio had actually mounted a bike.

Moreover, the wooden bicycle installed for the first time and all structural accessories were handmade by Mo Shouren.

He is also handy to install himself.

When it's time to actually switch to a steel casting mold.

Several times it was the wrong part.

Lin Ran didn't make a sound when he saw it.

All progress comes from mistakes.

There is no progress without mistakes.

If you install a wrong part, you have to dismantle it and start over again.

The three of them were sweating profusely from work.

There are only three days until the Mid-Autumn Festival, which is the best season of the year.

The autumn is so refreshing that it can make three young men sweat profusely.

It can be seen how many times they are assembled.

It wasn't until dusk that the three of them actually assembled the bicycle.

Good guy, Datang's first bicycle was officially born.

It can also be said to be groundbreaking, and the first bicycle in history was born.

Its significance has trans-age significance.

With a structure more than 1000 years later, it landed in the Datang world in advance.

"Teacher, do you see if it is correct?"

Li Tai wiped the sweat off his face, and said excitedly.

Lin Ran didn't need to look to know that their assembly was completely correct.

"Give me the wrench and snap made by Shouren."

Lin Ran took over the tool and strengthened several key parts again.

"These places must be reinforced, otherwise, if they become loose, it will not only have a great impact on the life of the bike, but also cause hidden dangers to the rider."

"Come and fill up the tires, and let the teacher try the first bicycle of our design institute, and see how it works."

Mo Shouren immediately brought the pump and started pumping it up.

This pump came out a few years ago.

With the advent of the carriage with wheels, this pump was also designed by Lin Ran.

Otherwise, the carriage tires are easy to leak air.

Especially when the technology is very immature today.

Basically, it needs to be inflated every three days.

Otherwise, it is difficult to ensure that the tire gas is in a full state.

After Mo Shouren inflated the front and rear tires, Lin Ran rode on the seat.

This feeling made him extremely complicated.

Bicycle, this is my previous life, the best memory of my childhood.

Going to elementary school and junior high school, all rely on cycling.

The father's cheek appeared in front of Lin Ran again.

It was he who taught Lin Ran to ride a bicycle.

At that time, I was really stupid.

When I got into the car, my hands trembled, and I couldn't even hold the handlebars.

It was the father, holding the back seat of the car with both hands.

Encourage yourself to ride forward boldly.

After many attempts.

Father finally let go of his parents' grip on the back seat.

And I also learned how to ride a bike.

"Teacher, what's wrong with you?"

Seeing the teacher sitting motionless on the car seat, Li Tai asked suspiciously.

Because the teacher's expression is too heavy, as if he has a lot on his mind.

"It's okay, teacher is okay."

"Teacher, thinking about you guys, you are so amazing that you actually made a bicycle."

"Teacher, I will definitely ask for credit for you."

Lin Ran's words made Yuan Tiangang and Mo Shouren very happy and excited.

As for asking for credit but not asking for credit, for Qingque, who is now indifferent to fame and fortune.

Not the slightest bit of allure.

After Lin Ran finished speaking, he started to ride.

The hall of the design institute has a very smooth floor.

Let Lin Ran pedal the bicycle very quickly.

Li Tai, Li Chunfeng, Yuan Tiangang and Mo Shouren all stared wide-eyed.

They couldn't have imagined that the bicycle could run so fast under the pedal of the teacher.

And what makes them even more incredible is that.

The teacher seemed to be very familiar with this bicycle.

Obviously it is the first in the world?

Why does the teacher ride on it, so that they can feel, there is a feeling that the human and the vehicle are one.

Amidst the cheers of the four people, Lin Ran rode for more than ten laps before giving up.

"Great, this bike, the teacher declared a great success."
