Hearing Lin Duoduo call her by her full name, Lin Wanwan stuck out her tongue.
Only when she was extremely angry would she call her by her full name.
Lin Wanwan, who originally intended to tease her younger sister a bit more, had no choice but to back down this time upon seeing Lin Duoduo’s puffed-up, angry little face.
Wretched kid, can’t take a tease at all.
She placed the blueprint in front of Lin Duoduo.
“Sister, this is a space expansion blueprint.”
“Space expansion blueprint? What’s that?”
Lin Duoduo was a bit confused.
“Is this thing very valuable? Why are you acting so excited?”
“Valuable? This is no longer something that can be described as valuable. The space expansion blueprint in our hands can increase the volume inside our RV by one cubic meter without changing the exterior appearance of the RV.”
“Think about it—how many things can one cubic meter hold?”
Seeing her sister’s excited appearance, Lin Duoduo scratched her head.
“Sister, tell me first, how big is one cubic meter?”
“Ugh.”
Hearing Lin Duoduo’s question, Lin Wanwan felt like she had thrown a punch into cotton.
Explaining the concept of cubic meters to a first-grade primary school student was simply playing the lute to a cow.
Lin Wanwan gestured a length of one meter before speaking up again.
“Look, this is the length of one meter. A so-called cubic meter means length, width, and height are all this long.”
“Sister, what are length, width, and height?”
“Ah.”
Lin Wanwan felt like she was going to be foolishly frustrated to death by herself.
When she mentioned length, width, and height, it wasn’t her sister’s fault for not understanding—it was simply that she hadn’t considered Lin Duoduo’s age at all.
This time, she briefly recalled things from home before speaking again.
“Do you remember the box where you used to store your toys, that big pink one?” Lin Wanwan asked.
“I remember!” Lin Duoduo nodded. “I remember it even had a pattern of Lotso the Strawberry Bear on it.”
“Right, that exact one—the box that could fit you inside. A so-called cubic meter is roughly as big as that box of yours.”
Hearing Lin Wanwan mention her toy box, Lin Duoduo closed her eyes and thought for a moment.
Then, comparing it with the space inside the van she was sitting in right now, she realized it was indeed quite large.
If calculated based on her toy box, the back of this van right now could only fit about four of them.
So adding one cubic meter was indeed adding a lot of volume.
Lin Wanwan suddenly thought of something, and she asked Lin Duoduo.
“Sister, earlier you could sense that a monster would come out of this treasure chest, so can’t you sense what kind of loot the monster inside the treasure chest can drop?”
“Huh?”
Hearing Lin Wanwan ask her like this, Lin Duoduo’s little brows knitted together, and she thought for a bit before speaking again.
“Sister, I truly can only sense whether there’s danger inside. As for what can come out, I can only roughly feel whether it will be of great use to us in the future. But as for what this kind of monster can drop as loot, I really don’t know.”
Hearing Lin Duoduo say this, Lin Wanwan felt a bit regretful.
If her sister could sense that this rat could drop a space blueprint, then even if she risked her life, she would slay all the rats to increase the volume of her van.
However, her sister could only sense the items already existing inside the treasure chest and could not sense secondary drops, which could only be said to be a slight pity.
Lin Duoduo obviously thought of this point as well, her small face creasing into the shape of a steamed bun.
“Sister, am I too useless? If I could know that the rat could drop such a valuable blueprint, wouldn’t we not have to work so hard?”
Hearing the downcast tone in her sister’s voice, Lin Wanwan patted her head.
“Silly girl, if you knew, you would definitely have told me. This isn’t your fault. In fact, you’ve already helped me a lot right now. Don’t think so much, okay?”
Hearing her sister say this, Lin Duoduo raised her head.
“Sister, is what you said true? I feel like I’ve been really useless these past two days. Not only do I eat a lot, but I also fell down from the car compartment, causing you to get hurt. Now even my sensing isn’t working very well.”
“Silly girl, you’re overthinking it. You’re already doing very well right now. As for eating a lot, I estimate it’s an aftereffect of using your sensing ability.”
“Is that so?”
“Mm, as long as you don’t overthink things, you’ll be fine.”
Seeing her sister say this, Lin Duoduo nodded earnestly.
“Sister, I will work even harder in the future.”
“Good.”
Lin Wanwan was also someone who had self-studied several child pedagogy books, so naturally she wouldn’t crush Lin Duoduo’s confidence.
Now that Lin Duoduo’s mindset had been adjusted, the next step was considering where to add this space.
Lin Wanwan sized up the van’s back compartment, then handed the blueprint to Lin Duoduo.
“Sister, go add this one-cubic-meter space blueprint behind the right car door over there.”
“Okay.”
Duoduo took the blueprint, crawled to the back of the car compartment, climbed over two bundles of cogon grass, and arrived at the rear seat area.
She pointed at the right side car window.
“Sister, do you mean adding it here?”
Lin Wanwan nodded.
Seeing her sister agree, Duoduo slapped the blueprint onto the right car window without hesitation.
The blueprint turned into sparkling specks, merging directly into the car window.
Then the car window stretched outward as if being pulled by a pair of invisible giant hands.
Soon, looking from the inside, a section of the van’s window seemed to bulge out.
The two sisters, Lin Wanwan and Lin Duoduo, opened the car door; looking from the outside, the car compartment unexpectedly had no changes at all.
“Perfect.”
Lin Wanwan was very happy.
The two sisters closed the car doors tight, turned on autopilot, and continued forward.
“Duoduo, regarding the remaining two chests, go sense them again. Which chest do you think we should choose?”
Lin Wanwan was becoming more and more convinced of Lin Duoduo’s intuition now.
Lin Duoduo closed her eyes, and after a short while, she spoke up again.
“Sister, I feel like they’re really roughly equal in my intuition, but if we really have to choose, let’s choose this Level 3 chest.”
When making this choice, Lin Duoduo’s small face was completely covered in an expression as if she had eaten bitter gourd.
Choosing the Level 3 chest?
Hearing her sister’s choice, Lin Wanwan wasn’t surprised at all. Because if she had to choose between a Level 1 treasure chest and a Level 3 treasure chest under supposedly equal value, she would definitely choose the Level 3 treasure chest as well.
“Alright, I feel the same way.”
Lin Wanwan didn’t want her sister to bear the pressure of choice; in case the items from the Level 1 treasure chest turned out good, the little kid would definitely blame herself again. So Lin Wanwan proactively expressed her own thought.
Hearing her sister say she would also choose the Level 3 treasure chest, Lin Duoduo’s small face immediately relaxed.
Seeing her expression, Lin Wanwan smiled.
Children truly couldn’t hide their emotions, with joy, anger, sorrow, and happiness all displayed on their faces.
“Come on, sister, go open that Level 1 treasure chest and see what treasures your little hands can draw out.”
