only……
My own beginner elf…
Can... reach the duck? !
"Kodak, don't sleep...Qiuqiu! This is...the elf battle battlefield!!"
"At your age and stage, can you sleep?!"
Faced with the urging of trainer Yang Kaibai to beg his grandfather to sue his grandmother, Kodakya still stood as motionless as a mountain... holding his head with melon seeds, frowning, inscrutable...
However, it falls over at the first touch!
Sleep wherever you fall.
…
Yang Kaibai: Send it! I'm going to do it right away!
Kodak Duck: When I fall asleep, the whole world will tremble! Gua!
Yang Kaibai: Stop croaking, Kodak, I don’t know if the world is trembling or not, but I have already started to tremble!
Kodak Duck: You are my whole world! Gua!
