The 9th Class Swordmaster: Blade of Truth - Chapter 100: What is the Destination?

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!

He woke up in a familiar world that had vastly changed.

His familiar school had become a mystical school that teaches magic, encouraging everyone to become a mighty magician.

Outside the city, many wandering magical beasts and monsters attacked and preyed on humans.

His world of advanced science changed into one that praised magic. Despite this, his ambition in life, and his social status remained the same; one of the dregs of the society with a struggling father and a disabled step sister that couldn’t walk.

However, Mo Fan found that when most people could only practice a single major element of magic, he was a Versatile Mage!

‘He’s so cute I want to kick him flying through the air.’

Bai Yao runs a seafood restaurant in a seaside town. One day, he saw a small sentient sea otter being bullied.

Out of pity, he helped out the little sea otter.

The sea otter acts quite defensively, baring his teeth, all while still covered in wounds yet to heal.

His way of saying thanks, is gifting Bai Yao an oyster in his pocket that’s been sitting there for who-knows-how-long.

Bai Yao ends up bringing the wounded and exhausted little sea otter back to his restaurant, giving him food and a shower.

Though the sea otter is still quite scaredy and defensive. He wouldn’t let Bai Yao rub his cute little face, or even ruffle his fur.

That’s not all the quirks of the little sea otter either. Bai Yao realised he’s a dummy that didn’t even know how to anthropomorphise.

Later that day, Bai Yao wakes up in the middle of the night, when there is something soft he’s holding in his hand.

He looks, and sees the little sea otter has put his paw in his hand. The sleepyhead is also snuggling on him, his head brushing against his chest.

Not feeling drowsy enough to sleep anymore, Bai Yao just props his head on his arm, watching until the otter finally wakes up.

When he finally does, he looks around, and sees that it’s Bai Yao; he squeaks, and then nestles his face against the fingers of Bai Yao.

Amused, Bai Yao asks, “oh? I thought you were a tough little guy that didn’t like petting?”
