My wife is a squeamish bag

Chapter 228 My Beibei is Really Smart
"Bebe, thank you."

Back in the room, Qi Jingyu hugged An Beibei's shoulders, looked down at her bright eyes, and said deeply grateful.

An Beibei was confused, supported his waist and looked up with a smile and asked, "Thank me for what?"

"Thank you for not only being willing to teach me the method of modifying bows and arrows, but also planning to give me all the credit."

"Grandma told you everything? Actually, it's nothing, we are a family!"

An Beibei said carelessly, "Then what do you think? Do you want to use this method to fight once? I think everyone really wants to go back to Kyoto."

"I just want to tell you, never show your things in front of people in the future, those may bring you danger."

Qi Jingyu said solemnly.

Especially they still don't know the purpose of the person behind who changed her into Da Chu's clothes and left her in the dense forest.

"Will they be tied up and burned?"

An Beibei became nervous all of a sudden.

Seeing her frightened face, Qi Jingyu didn't tell the worst result after all, "No, it's just... maybe you won't be free."

"No, I don't want to lose my freedom."

An Beibei shook her head violently, and said with a sad face in a moment: "What if... what if I can't hold back and accidentally expose it? I didn't like lying or being good at lying since I was a child. Lying is more dry for me. The work is still difficult."

"It's okay, even if it is exposed, there is still me, just try to pay attention."

"But... I like those, and besides those, I don't know anything else, I can only be a waste."

At the end, An Beibei was very depressed.

Qi Jingyu hugged her distressedly, "It's okay, do what you like, as long as you try not to show it in front of outsiders. You are not a waste, you are better than many people in Dachu. Look, I used you to do it today." This sleeve crossbow shot at the wing of a black eagle."

"really?"

An Beibei was both surprised and delighted.

Theoretical design and the mood of seeing the actual results are completely two different things.

"Is this your homemade arrow?"

An Beibei pointed to Qi Jingyu's somewhat rough but sharp arrows on the table and asked.

"Well, I picked five different trees, and guess what worked best?"

An Beibei raised her eyebrows confidently, and picked out a dark brown arrow, "Needless to say? Of course it's this one."

"My Beibei is really smart, she can guess right!"

"I didn't guess it, but inferred it based on the density of the material."

After An Beibei finished speaking, Qi Jingyu looked at him with a puzzled face, and explained patiently: "The density of a substance refers to the ratio of the mass of a certain substance to its volume, that is, the mass of a certain substance per unit volume. Simple In other words, for things of the same size, the heavier they are, the denser they are... Unfortunately, there is no iron, if the material is replaced with iron, the lethality at this point is completely incomparable."

Iron?

A certain place flashed in Qi Jingyu's mind, and then he suppressed the thought in his heart.

Now is not the time.

"Even as it is now, it is already very powerful."

An Beibei curled her lips, a little dissatisfied and said: "It's only a little bit stronger than your bow here. In fact, I originally planned to design a mechanical crossbow for you, but that thing is eye-catching once you use it."

Qi Jingyu rubbed her head, and said with a smile, "That's all, it's easy to carry, and it can catch people by surprise."

"That's true. Let me tell you, I also designed a self-destruct device. It's just this little buckle here. Once you break it off, the whole sleeve crossbow will fall apart. Even if someone gets it and wants to dismantle it for self-study, it's a waste of effort. "
