The boy knew why.
Because... this monster had saved him before.
When he had been filled with despair.
"No, I still want to thank you."
It had appeared right by his side.
Though it had wanted something from him...
This monster really had saved him.
Honestly, when he saw Yuan Yuan fly away, he had felt a rush of satisfaction.
Though that quickly turned to fear that Yuan Yuan might be hurt.
Fortunately, this monster hadn't gone too far.
"Human."
The strange, hoarse voice interrupted the boy's thoughts.
He blurted out, "My name is Zhao Yihuan."
"You can call me Xiao Yi."
"What's your name?"
The boy's face was full of excitement.
Then his expression softened. "Sorry, did I interrupt you?"
"What were you trying to tell me just now?"
"..."
"I like your blood very much."
The boy froze.
It liked his blood?
"Let's make a deal."
The strange, hoarse voice was flat. "I can protect you."
"In return, I want your blood."
"Are you willing to accept this deal?"
"Protect... me?"
Although he felt like what had happened today probably wouldn't happen again, the boy clenched his fists, unable to hide his joy and excitement. "You want to make a contract with me?!"
"..."
The monster was a little surprised by the boy's unexpected reaction.
And what was a contract?
"I need your blood."
The monster repeated its request.
"Mm."
The boy nodded. "Okay."
"...Why are you so quick to agree?"
The monster was puzzled.
"Huh?"
The boy didn't understand the monster's question.
"Ah, how much do you need?"
A beat later, the boy realized he might have overlooked an important question.
"..."
The monster was speechless.
"I'll live inside you."
"I won't need much each day."
"Oh, I see..."
The boy
