"Daddy! I'm back! As soon as he opened the door, he called out to his father.

In the past, every time he went home in vain, he would scream like this, and then the white father would put down the work in his hand and hold it high in vain, "My dear Baibai is back." ”

However, this time the White Father did not appear.

"Isn't Daddy home?" Regretting it in vain, I walked into the living room and found a letter on the coffee table.

With a sense of foreboding, she picked up the letter and opened it.

My favorite white:

In vain, Dad is gone.

I'm sorry for not saying goodbye.

But Dad didn't inform you because he didn't want it to affect your studies.

Can you forgive Dad?

Dad will be back soon, and you'll have to take care of yourself while I'm away.

Don't read it.

Your favorite dad.

"Daddy, where have you been?" Ran to the window in vain, looked at the crowds on the street, and muttered.

Although Father Bai loves Bai Bai very much, he didn't tell Bai Bai anything about him, which seems very mysterious.

Bai Bai has no mother since he was a child, and every time he sees other children with his mother and relatives, he is very envious.

In vain asked his father, "Dad, who is my mother?" ”

"Your mother is the kindest person in the world, and I hope you can be a kind person too."

"Hmmm! I will. But Dad, are there any other relatives? ”

"No, Dad is alone, don't ask these questions in the future."

"Oh, I see."

At that time, Bai Bai was very young and didn't know what these words meant, but now that I think about it, it seems that there is a big secret in it.

……

Seven days later, Yucheng Academy.

"Are you all there?" Teacher Li looked at the students on the playground and asked loudly.

In addition to the six of them in vain, there were five people in the third grade, including Ling Feng and Yan Huang.

"It seems that classmate Dong hasn't come yet." Bai Bai looked to the side and replied honestly.

"I'm coming, I'm coming!" Hearing Chubby's shout, everyone turned their heads to look and saw Chubby running over with "a mountain" on his back.

"Huhu—I'm tired."

Chubby put down his half-human-high backpack and wiped the sweat from his forehead.

"Dong Peng, what are you?" Teacher Li narrowed his eyes and asked seriously.

"Oh, these are my precious snacks!" Chubby vigilantly picked up his backpack of precious snacks and said, "They are my life!" ”

"Although the academy doesn't stipulate that you can't bring snacks to the game, you can carry a big bag to watch it like this!"

"Ahh Don't! I can't live without this brand of snacks! ”

"Classmate Dong, why don't you use the space ring?" Bai Bai reminded in a whisper beside him.

"yes, why didn't I think of that?" Chubby scratched his head and suddenly realized.

Chubby hurriedly put the backpack into the ring, as if nothing had happened just now.

"Now that we're here, let's go." Teacher Li gave the order to go.

"Teacher, how are we going?" Xiao Pang was puzzled, "The Holy Dou Advanced Academy is so far away from our Yucheng, is it by car or by plane?" ”

"No, this time, in order to save time, we decided to use the newly built space portal in Yucheng."

"Spatial portal!" The students were very surprised when they heard what Mr. Li said.

The space portal is a product developed by the Saint Dou Federation in recent years, using a powerful electromagnetic field to resonate with the free space element force, as long as the ratio of the magnetic field strength and the space element force is equal, a two-way space teleportation channel can be opened.
