The cannon fodder female supporting role is busy in the book, and she gets mad when she disagrees wi

Shen Yanxi's suspicion of Shi Lidie reached its peak the moment he saw the bicycle.

He pointed at a seven-year-old child and trembled as he watched him wobbling by on his bike:

“Is this… a bicycle?”

A-Dong was surprised when he heard this:

"Mr. Shen has good eyesight. It is a bicycle. Have you seen it somewhere else before? How do you know it is called a bicycle? In our Qingping County, there are only a few bicycles in use."

"The one who just rode by was the Crown Prince of our Great Yin Dynasty. I heard that His Majesty came to inspect the princess's fiefdom and was impressed by the teaching atmosphere and model of our fiefdom school, so he asked the Crown Prince to stay here to study."

"Besides His Royal Highness, only the princess, Principal Chen of the Girls' School, Master Qin, Master Gu, Lord Chen, and Lord Du have one. After all, it is said that this bicycle is not easy to produce, and the current production volume is low."

"The princess promised that if bicycles could be mass-produced, she would open a bicycle factory and produce more bicycles so that ordinary people could afford them if they saved up some money."

Shen Yanxi: ...

After confirming through eye contact, the princess was also a time traveler.

And judging from the series of measures taken by the princess in her fiefdom, she should be a kind person who cares about the people.

Because, she did not act superior to others just because she traveled through time, nor was she assimilated by this feudal society. She was seriously working to improve people's livelihood and seek welfare for the people.

In that case, let him help.

The princess said she saved him because he was useful, so he had to become a useful person. When he was not sure whether he could wear his clothes back, he had to hold on to the princess's thigh and take root here.

"I'm not going to walk around anymore. I'm going back." Shen Yanxi said, turning around and going back to the princess's mansion.

After returning to the yard, he asked the servant to bring paper and charcoal and started drawing.

He was a genius in mathematics and physics, and he majored in weapons science, materials and engineering. He was very familiar with various equipment parts and their assembly. It was a piece of cake for him to modify the bicycle according to the current situation.

In addition, after he escaped from the territory of the Southern Yi, he knew to some extent that the Dayin Dynasty was at war with the Southern Yi. If he could help the Dayin Dynasty design new weapons, wouldn't he be able to prove his own value even more?

He used to do research, focused and immersed.

The same thing happened after he came here. From that day on, except for three meals a day, he locked himself in the yard to draw and never came out.

Seeing this, A-Dong reported the situation to Shi Lidie, who then ordered:

"Let him be."

"Prepare his meals on time and take good care of his daily life. Don't worry about anything else. As long as he doesn't do anything that harms the princess's mansion or his fiefdom, everything will be up to him."

In this way, with Shi Lidie's indulgence, Shen Yanxi secluded himself for seven days.

Seven days later, he produced two blueprints, one for bicycle improvement and the other for weapon improvement.

Shi Lidie looked for drawings exchanged through the system. Some of them she could modify herself, but some she really couldn't do anything about. After all, she was not a professional in this field, so she could only rely on others.

However, the system points are limited, and since she completed the plots of three books, the Afeng system no longer assigns tasks to her.

The points you have accumulated in the past will be reduced as you use them.

Although she could spend thousands of points to exchange for the corresponding skills, she was unwilling to do so.

She had previously exchanged for skills in traditional Chinese medicine, and could make up for it through Aya's elegant mission, but if she exchanged for skills such as mechanical engineering, there would be no conditions for her to put them into practice in the current social background.

Therefore, the appearance of Shen Yanxi just made up for Shi Lidie's shortcomings in this aspect.

"Princess, please take a look." Shen Yanxi handed the drawing to Shi Lidie.

Shi Lidie took it and looked at it carefully.

While she was looking at the drawings, Shen Yanxi was secretly looking at her, trying to see something from her face.

Because he wrote everything in simplified Chinese on the drawings.

If Shi Lidie can understand all of it, it proves that she is indeed a time traveler.

He soon verified his guess, because Shi Lidie remained calm and did not seem to be confused at all. She knew the meaning of every word accurately.

After a long time, Shi Lidie put away the drawings, looked up and smiled:

"Have you seen enough?"

Shen Yanxi blushed again and stammered:

"I've seen enough... No, no, I didn't mean to offend the princess."

"I've seen the blueprints, they're very good. What kind of work do you want to do?" Shi Lidie asked. "I have a research and development department here, and we're currently trying to find ways to improve bicycles. How about I send you there?"

"No...no, Princess, can you give me a studio alone? I'm not used to being with others." Shen Yanxi said.

"Don't you have any classmates in your graduate studies? Have you never worked on a project with anyone?" Shi Lidie asked.

"No, I am the only one under my mentor." Shen Yanxi shook his head. "Generally speaking, I work on projects alone. Only when the projects are particularly difficult will my mentor be consulted."

"Okay, since you don't want to cooperate with others, there's no need to set up the studio in the R&D department, just in that yard." Shi Lidie nodded, "You can modify the yard where you live by yourself. In addition to the dormitory living area, you can decide where to divide it into a work area. Then tell Adong your needs and he will help you prepare things."

"Thank you, Princess." Shen Yanxi bowed and turned to leave.

But before he left, he endured it again and again, and finally couldn't help it, so he opened his mouth and said:

"Princess, I have a question for you. I will feel anxious if I don't get the answer."

"What's the problem?" Shi Lidie asked.

"That... odd numbers change but even numbers don't change?" Shen Yanxi said the necessary code for the time-traveling army to recognize each other.

Although he didn't have time to read novels before, he had seen similar stories on the Internet, saying that after traveling through time, they would rely on this secret code to recognize each other.

Shi Lidie laughed when she heard it, and she said directly:

"You don't have to test me. Don't you already know the answer? Otherwise, you wouldn't have come to me today with a drawing full of simplified Chinese and English characters."

"So, you really are?" Shen Yanxi was immediately surprised.

"I was wondering when you would find out." Shi Lidie said with a smile.

Although she has not yet recognized Shen Yanxi, in fact her behavior has not concealed her identity. As long as you are careful, you can still detect her identity.

After all, Shi Lidie is an excellent actress. When she was undercover in Ye State in the past, she relied on her acting skills to fool the other party. If she really wanted to conceal her identity, she would not reveal flaws everywhere.

When Shen Yanxi heard Shi Lidie admit it, his face flushed with excitement. He asked tentatively:

"Can I ask you, what was your name before you traveled through time? Where are you from? Princess, don't get me wrong, I don't mean anything else. I just feel that it's more intimate to meet a fellow countryman, so I just asked casually."
