When the bird race wanted to flatter the king of the wolf race, he was thrown out directly by his parents. After that, he had been tossed like a toy by others from one place to another, numerous times. Finally, he ended up in front of the black wolf.

There was a rumor saying that the black wolf was the most ferocious existence in the wolf palace. And the black wolf’s favorite food was raw chicken!

He always excitedly gnawed the chicken, there was a possibility that blood could splatter everywhere!

Qiao Xi: I feel like I’m going to die.

And when Qiao Xi fell in front of the black wolf—

The black wolf had sharp fangs, fierce eyes, and a terrifying aura. The black wolf opened his mouth and approached Qiao Xi…

“Auwoo! Auwoo! Auwoo!”

Qiao Xi was frightened out of his wits and immediately fell onto the ground. He unmanageably changed into a human form. His body was shivering uncontrollably, thinking to himself that he was going to die.

However, just when the black wolf saw Qiao Xi’s human form, he unexpectedly turned silent.

After standing still for a while, he suddenly lifted his paw and touched Qiao Xi’s pretty little face, he stated calmly: “From today onward, you’re my little brother.”

Qiao Xi, whose eyes were filled with tears: “…?”
…

Later, the black wolf ascended the throne in the wolf race.

Someone saw the black wolf carrying a chicken in his arm, and couldn’t help but say with a smile, His Majesty, the Wolf King surprisingly carried a ration with him, which was really interesting.

Suddenly, the Wolf King’s face darkened. He said calmly without any smile on his face: “This is my wife.”

He also ate this small one every day, but not as a ration, because this was his little treasure.

My older brother, who was my only family member, lost his memory. “I have a sibling? Are you kidding me?” He was a fool who cared for me ever since he brought me from the temple… “I can’t even take care of myself, so what is this…” I left the family because I didn’t want to be a burden to my older brother, who had no memory, and was helpless in the tragedy that followed. So I turned back time. That too, to the point when my brother lost his memory. “I don’t have anything in my head, so I don’t know what to do next. What if I have a kid with me?” We must not repeat the tragedy of the past life. So I grimly said, “That’s right. I don’t have anything on my brother’s head right now.” “…What, what?” I chuckled and took out a document I had prepared. The contents of the document, written in crooked, large letters, were simple. [I transfer all the property in my name to my younger sister.] While my gaping older brother was checking the documents, I took out his seal from his drawer and smeared it with ink. Then I put it in his hand and said with a very sad expression. “So stamp it. Now.” I will protect you in this life.
