At two o'clock in the afternoon, Hedou stood at the front desk of the post office, drinking tea while bragging with several goats beside him.

"This is the latest product of the Time and Space Post Office - the Ultra-Time and Space Observation Crystal!" An elderly goat pointed at a small mirror on his wrist with an excited look on his face.

"The name is very high-end, but it looks like a watch wearing method. If it doesn't work, it's just a watch, right?" He Dou complained after tasting the tea.

"Of course not. This super-time and space observation crystal can cross the timeline to see subsequent events that occurred in the space you are going to." The elderly goat smiled.

"Use this to observe whether the time and space we went to had any major impact after we left." The elderly goat explained the role of this crystal.

"Didn't our participation not affects time and space? Even we themselves will become part of the closed cycle of time and space." He Dou frowned, a little confused about the significance of the use of this crystal.

"Ahem, although time and space will repair itself, our attitude that will never disturb time and space is correct." The elderly goat waved his hand, with a smile on his face.

I understand! Face project!

He Dou nodded to express his understanding.

"Let's have fun for you, I'm going to do a mission." The elderly goat smiled and handed the crystal to He Dou, then walked into the room inside the post office with a letter.

He Dou played with the crystal a few times and hung it on his wrist.

"Mr. Postman! Mr. Postman!"

A vibrant voice came in from outside the post office.

He Douxun looked at him and saw a young and cute little girl jumping over.

Her little face was gray, as if she hadn't washed it after the fight. She had a hat on her head. Although it was a bit worn, it was still well preserved.

"hello."

He Dou showed a kind smile and watched the little girl stand in front of him.

Yin Xiaohui and the other three have received the task and have traveled through time and space to deliver messages. Only he has not started delivering messages yet.

"Hello brother postman!"

The little girl bowed heavily, swinging her hands back high, looking very cute.

"Hello, hello." He Dou smiled and picked up a candy in his hand and handed it to the little girl, "Do you have anything you want to send it?"

"Please give this..." The little girl's eyes shone with light and handed over a postcard.

"Mail to me ten years later!"

The little girl's eyes were blinking, like stars in the sky.

"Are you going back and forth postcard?"

He Dou took the postcard and looked at it, then picked up the file packaging bag on one side and packed it.

"I want to bring back my future reply." The little girl pouted and looked very cute.

"Mour this precautions." He Dou picked up the document that recorded the letter instructions and handed it to the little girl.

"After receiving the letter, the future self cannot tell you any information that is beyond the times in the reply..." The little girl muttered while looking.

"Remember all these, and remember them until ten years later." He Dou looked at the little girl in front of him and recited them seriously.

"I remember!"

The little girl jumped excitedly and returned the documents to He Dou.

"Remember it?"

He Dou picked up the file packaging bag and walked out of the front desk, squatted in front of the little girl and asked.

"Yeah! I remember it all!"

The little girl raised her chest and looked proud.

Although her clothes looked very worn, she exuded a sunny atmosphere from the inside out.

"Then brother will go and deliver the letter to you now. You can sit here and wait, I will be back soon!"

After He Dou finished speaking, he took the little girl to a row of seats next to the hall.

………

Picking up the file bag, He Dou came to a strange gate inside the post office.

"It's finally here. It's really curious about the feeling of time traveling..."

He Dou smiled and began to operate the rows of buttons on the door.

"In time... it's ten years later."

He Dou muttered in his mouth, adjusting the data to ten years, and chose to travel along the timeline.

"It's really a fool-like operation..."

After pressing the button, He Dou shook his head helplessly.

Just pressing a few buttons to get through time, which really makes people feel a bit magical.
