That was the blueprint for a silencer gun.
When Su Qingzhu was thinking about giving gifts, the one that gave her the most headache was the gift for Si Jingguo.
The watch, belt, wallet, etc. are inappropriate, and the notebook and pen are not in line with his status. After all, he is a soldier, not a politician.
After much thought, Su Qingzhu found a set of ancient gun design drawings, which allowed him to reduce the weight, change the appearance, and add a silencer without changing the material.
She spent a lot of money to buy the smartphone, which contained a lot of good stuff, but none of them were applicable.
This should be what they need most to kill spies at this stage.
Si Jingyu came over curiously, and when he saw the design clearly, he snatched the drawing and stuffed it back, then pulled Su Qingzhu back to his room with an unexpected look on his face.
Si Jingguo frowned, while the others were confused.
"Jingguo, what's going on?" asked Si's father.
Si Jingguo shook his head silently.
Although Su Qingming was sitting next to Si Jingguo, he was drinking tea and didn't notice what happened.
Su's father and mother looked at each other. It was the first time they saw Si Zhiqing's expression change, and they couldn't help feeling a little worried.
Little brother Su, on the other hand, acted as if nothing had happened. He sat next to Grandma Si, swinging his legs and eating biscuits, and occasionally feeding Grandma Si a piece.
The grandparents and grandchildren enjoyed the meal very much.
Grandma Si touched the child's forehead and said, "Drink your tea. Don't waste such good tea."
When the head of the family speaks, everyone naturally follows his orders.
Grandpa Si happily brought back a cup of tea for his wife to try, and asked little brother Su: "Xiao Lang, do you want some tea?"
Little brother Su tilted his head and asked, "Grandpa, is the tea delicious?"
At home, he only drinks warm water and milk, and has never drunk tea.
When others smelled the fragrance, he just felt it was pleasant, but he had no particular desire to drink it.
Grandpa Si knew that the baby had never had tea at home. After thinking about it, he picked up the milk and gave it to him. "It's not as good as milk. Xiaolang should drink milk."
"Thank you, Grandpa!" Little Brother Su held the Dun Dun Dun and drank half a cup, put it back in the cup, and continued to eat his cookies.
Inside the house, Si Jingyu returned the envelope to Su Qingzhu and said, "Keep it and don't take it out again."
Su Qingzhu looked at him with a smile in her eyes. Traveling to this strange era and meeting him was probably the greatest luck in her two lives.
She handed him the blueprint and quickly spoke to stop him from speaking. "Don't worry, this is adapted for this era. The materials are available, and the technology only needs slight changes."
She opened the drawing and showed it to the skeptical Si Jingyu.
"Here, changing the material can reduce weight. Here, changing the mold and material can make the grip more stable. And here, installing a small device can achieve maximum sound insulation. Everything else remains the same."
Changing technology is what Si Jingyu is worried about, but it is not his biggest concern.
What he was most worried about was the source of the drawings.
How could she explain that she had such detailed design drawings.
He expressed his concerns.
Su Qingzhu sighed, "Well, this is about 'our master' raiding a drug factory. Out of curiosity, he took a gun home to study, and that's how he got these blueprints."
Si Jingyu was stunned. Can it be used like this?
Considering that "experts" do whatever they want, it's not impossible that they are interested in guns.
After thinking for a while, he accepted the blueprint and said, "Find a pen and a notebook and give them to him in person. I'll give him the blueprint in private."
Those people only knew that the master knew him and had been targeting him all along. He didn't mind, but he couldn't drag Su Qingzhu into it.
His weaknesses are his family and her.
Those people couldn't judge whether her family was important to him, so they wouldn't dare act rashly.
But her weaknesses are her family and the Zhang family. Even if he sends people to protect them, he cannot guarantee that they will be safe.
Therefore, exposing him is much better than exposing her.
As sharp as Su Qingzhu was, she figured out the key point in an instant: it was her negligence.
Her heart softened. This man valued her more than himself.
"good."
After searching in the space, she finally found an envelope-sized leather notebook and a pen, and put them in the envelope.
Seeing that she had figured it out, Si Jingyu hugged her in his arms and said, "Don't do this kind of thing next time. Your safety is the most important thing."
Su Qingzhu nodded with a smile, "Okay."
When the two of them walked back hand in hand as if nothing had happened, everyone else secretly breathed a sigh of relief.
Su Qingzhu handed the envelope to Si Jingguo, who could tell at a glance that the contents had been replaced and couldn't help but glance at Si Jingyu meaningfully.
Si Jingyu ignored his brother and directly picked up his teacup and drank the almost cold tea.
"Oh, it's like a cow chewing on a peony, a waste of resources." Grandpa Si was heartbroken.
Si Jingyu didn't buy his grandfather's words and found that the wine tasted quite good. He poured another glass and drank it down as if he was going against his grandfather.
Grandpa Si was so angry that he didn't want to talk anymore.
When Su Qingzhu saw Si Jingyu and his grandfather getting along so well, without anyone else even giving them a second glance, she knew that the relationship between the grandfather and grandson was not as it seemed, and was actually very good.
The two families met for the first time and were surprisingly harmonious, with no barriers at all.
After returning home that night, Su's father and mother finally had a good night's sleep.
In the next two days, the Su family, accompanied by tour guide Chen Ke, visited the city and bought a lot of local specialties.
Time flies, and they are finally going back.
**
That day, Si Jingyu personally drove the Su family to the train station.
Si Jingyu gave the ticket to Su Qingzhu, stood aside with his luggage, and did not participate in the family's farewell.
