Tian Xinmiao had doubts in his heart, and scanned the contents of the letter again, but found nothing.

She frowned and put the letter away, packed it into a package, and put it in a box.

He's okay! It can't be that something has happened to prevent you from training, right?

But what could happen to him?

Tian Xinmiao was a little uneasy in his heart, leaning on the box and being stunned for a while, and was just about to rest after packing up, but heard a knock on the door.

"Sister-in-law, have you fallen asleep?"

"It's so itchy, I haven't slept yet, I'll open the door for you."

Tian Xinmiao opened the door under the kang, and Ruan Haoyan walked in with a sad face.

"What's wrong with my family Haoyan, her brows are furrowed so tightly, it's not good-looking."

Tian Xinmiao raised her hand and rubbed Ruan Haoyan's brows, and joked with a smile.

"Sister-in-law, I'm always a little unsure in my heart, I, can I sleep with you?"

"It's just to take a junior high school entrance exam, and it's not much different from the usual promotion exam, so why are you nervous?"

Tian Xinmiao rubbed her head, and suddenly found that this girl seemed to have grown taller recently.

"Sister-in-law, there are also people who can't get into junior high school, and it's not good if they don't take the test."

"With your grades, if you can't pass the test, will your class fail the test?"

"I-"

"Okay, you go get your school bag, get a good night's sleep tonight, maybe you won't be nervous."

Ruan Haoyan nodded and went to her hut in response, while Tian Xinmiao went to the hall.

The paper bag with the name of 'Ruan Haoming' written on it should also be a gift or something, and if there is Haoming, there will definitely be Haoyan.

Ruan Yongsheng and Wu were afraid that the little girl would be too excited to fall asleep after seeing the gift, so they didn't dare to show it to her.

In order to make the little girl feel more relaxed, it may be better to be happy and happy after seeing the gifts.

As Tian Xinmiao guessed, Wu and Ruan Yongsheng really wanted to wait for Ruan Haoyan to finish the exam before giving her the gift that she didn't know what she could do.

Tian Xinmiao persuaded Wu and Nguyen Vinh Thanh to return to his hut with the letter and gifts.

Ruan Haoyan then walked in.

Seeing the contents of the paper bag that Tian Xinmiao opened and spread out on the kang, Ruan Haoyan's eyes instantly lit up.

"Sister-in-law, what is this?"

"This is a gift from your eldest brother to you and your second brother, I don't know what it is, you can know after reading the letter he wrote to you."

Ruan Haoyan put down her schoolbag, picked up the things made by connecting seven bullet shells of different heights, looked left and right, and couldn't understand it, so she had to put it down and take the letter from Tian Xinmiao, who was smiling.

looked at it at a glance and finally found Ruan Haocheng's explanation of this thing.

It turned out that this was a sentry made by Ruan Haocheng after asking Zhang Chaoyang, because the length of the bullet casings was different, and the sound emitted was also different.

"Sister-in-law, the eldest brother said that it is called a platoon whistle, which means a row of whistles, which is made of bullet shells!"

Ruan Haoyan couldn't continue to read, dropped the letter, picked up the whistle, and tried to blow it.

Tian Xinmiao knew that this was called a whistle, and listening to the tune played by Ruan Haoyan, Ruan Haocheng should also have intercepted the length according to his own conjecture, and the pitch was not very good.

"It turned out to be a whistle, sister-in-law try to see if she can play a tune."

Tian Xinmiao picked up the platoon whistle left for Ruan Haoming and tried to blow it.

'Two tigers, two tigers, run fast, run fast...'

This song is the simplest, although the pitch is not very accurate, but when it comes out, it is still quite cheerful to listen to.
