"How do you open this door?" I asked Miss Kit about my brain down.

"Are you stupid? Push it away! Miss Kit tapped me on the head.

"Can't push, kit" I pushed harder, but didn't push away, and I wondered.

"There are no gaps above or below, no wonder you can't push it open. Generally, the door will leave two gaps above and below to make the air pressure the same inside and outside, but now there is no proof that the air pressure inside and outside is different. Miss Kit said and walked to the door.

"3.2.1, push." I counted down, and at the last second I pushed the door open with her and fell to the ground.

"Oh my god, get up and see, Lisa!" Miss Genius exclaimed, and succeeded in arousing my curiosity, and I got up with Miss Kriya, who was in a bad mental state, on my back, and looked at the place where the gold coin was brilliant.

"Miss Kriya, what are you looking for?" I asked her.

"Listening to my grandfather, it seems to be ...... Ahem, in a small box, noodles. Ahem, ahem, ahem......" Kria said intermittently.

"It's this box!" Miss Kit pointed to the small box, "There are several letters in there. ”

"Do you want me to read it out?" I asked Miss Kit.

"You ask Miss Kriya."

Miss Kriya nodded weakly.

"You sit down against that big box first." Miss Kit helped Miss Kriya.

"Hmmm......"

I caught a glimpse of Miss Kriya's hand reaching into Miss Kit's pocket.

"I started it!

First Letter:

Dear Chris and Kriya,

Now you should find this treasure, you must also find this puzzle difficult for those of you who are highly intelligent!

On this quest for treasure, you should help each other, and you should be reconciled.

My grandfather understood that I couldn't grow up with you and watch you start a family.

My grandfather hopes that you will grow up happily. See the gift in the big box, it's your birthday present.

Grandpa's time is running out and I can't swing with you, so finally, happy birthday to 12-year-old Chris and Kria.

Love your grandfather.

2nd Letter:

Dear Chris and Kriya,

It doesn't matter if you didn't find it before, just find it now.

I think my grandfather's time is running out. My life is coming to an end. I'm sorry I can't be with you anymore.

Now that you're thirteen years old, you should have a boy you like!

Kria should have learned equestrianism, and Chris has started to learn ballet.

You have to come to see your grandfather often! Grandpa is always welcome here!

Love your grandfather.

Do you want to read more? "I asked Miss Kriya.

"She seems to be asleep...... "Miss Kit leaned closer to her, her face a little miserable and bloody.

"Wait, she's asleep?" I put my finger on her carotid artery, and for a moment I felt more desperate than I had ever felt before, and I shook my head and said, "She's not asleep, she's asleep." ”

"Speak human words." Miss Kit didn't quite understand.

"She's asleep."

For a moment, the surroundings were quiet, and the silence was a little scary.

"I see." Miss Kit replied after nearly 10 minutes.

"So how are we going to bury her?" I asked her.

"Put her in that big box, I opened it just now and looked at it, and it was all pictures of her and her grandfather." Miss Kit carefully picked her up and asked me to open the lid of the box.

I put those letters in Miss Kriya's hand.

"Maybe that's a good ending!" Miss Kit said to me, looking up and closing her eyes.

"Indeed, the family is gone, and she can go to heaven to meet her dear grandfather, and her sister Chris. This is also a happy ending. I closed the lid of the box and whispered, "Miss Kriya, rest here." ”
