He asked Shuangying to pick up his daughter who was riding a dog and left the house.

Come to the street.

really!

It was so crowded that there was no way out, three circles inside and three circles outside.

They had no choice but to go to the teahouse and watch from a high place.

Then I saw a woman in casual clothes walking on the street, pushing an iron cart.

When the iron lump moved, it made a rattling sound!

In particular, the two things in the front and back that look like wheels make even louder noises.

[Wow!]

[Is this something from another world? It looks interesting.]

Mingxin's eyes sparkled. If they were smaller, she would still be able to play.

"Everyone, take a look, take a look!"

"This thing is called a bicycle. Once it's mass-produced, everyone will have one."

"Whether it's carrying people or cargo, the speed is very fast!"

Zheng Zhaoyi wiped the sweat from her forehead and greeted the people.

What is this?

As a science student in modern times, she is proficient in almost everything.

When I traveled back to ancient times, I thought I could become a concubine, eat delicious food, drink spicy drinks and relax.

Back to my old job again!

Moreover, everything in ancient times was very backward and everything had to start from scratch.

She is worse than cattle and horses!

A few days ago, after she returned to the palace with her daughter, she was summoned to the Yangxin Palace by Emperor Yongwu.

It was not because of her beauty that he wanted to sleep with her, but because he set up a new department in the Ministry of Works called the Kezhong Department.

And she is the director of the Kezhong Department!

All the subordinates are also newly equipped.

Fortunately, this fictional dynasty, the Dayong Kingdom, had advanced technology in iron smelting and alchemy.

After she drew the blueprint, she made a model of the bicycle parts in three days.

Another three days passed, and she worked day and night to prepare the medicine!

Finally, the first bicycle in history was developed.
