Classroom of the Elite (LN) - Vol 155 Chapter 1.0: Ike And Komiya

What’s not to love about my new life after transmigrating into a Pet-centered world?
There are mighty creatures that come in all shapes and sizes. They can either be cuddly companions, helpers in your daily life, daring scouts or strong fighters. Or all of the above. Not bad, huh?

I have a family, but the fact is completely overshadowed by my younger sister. She thoroughly hates my guts, and she makes sure that I know this. Every. Single. Day.
Did I mention that she’s disgustingly talented while I am a bottom feeder? A terribly handsome one at that.

I have free rein to run the family business on my own. A small and quaint Pet Store. It should have been great if not for the fact that the previous owner of this body was born with ZERO affinity to handle Astral Pets…

It wouldn’t be a proper transmigration without a gimmick or a system to pave my road to greatness, don’t you think? I have one, but I don’t know if I would be better off without it…

Yuchi traveled to the wild and ferocious world, where the heroes of all races lived in the world, and was arranged to be put in prison by others since he was born.

When others have completely forgotten this little transparent thing, he has already taken out the bamboo pole that accompanied him in his previous life.

There are souls of ancient gods and beasts in the vast wilderness of the world, rivers and seas.

This bamboo pole can communicate with ancient times.

Go fishing in the Nether Dead Sea and get the Lament of the Naga Siren!

Fishing in the Bone Ning River, get the onslaught of Mourning Murlocs!

Go fishing in the cave sky and deep pool, and get the golden pupil of the five-clawed dragon!

Hang candles in the sea and sky to fish, and get the real fire of the nine-tailed white fox!

Tens of thousands of years have passed in a flash, and gods and beasts from all walks of life come to congratulate them on their wedding banquet.

A certain giant couldn’t help asking: “Why are you so scary?”

Yuchi looked at the beautiful wife beside him, and in his mind he recalled the scene where he once stood standing in the dark sea and fought thousands of evil spirits…

Smiled: “Without him, it’s just luck.”
