A story about a traveler who crossed into a parallel universe, relying on his Proficiency ability to continuously grind experience and become stronger.
```
Inside the underground cave.
Chen Mu's eyes shone as he continuously inspected the red gourd in his hands.
About the size of a palm, with a belly as big as a fist, the entire gourd was a fiery red.
When held in hand, it felt like a lump of iron, seemingly as heavy as if it were cast from metal.
Yet its surface lacked the coldness of metal, instead exuding a faint warmth, resembling a hand warmer.
Upon attempting to infuse mana into the red gourd, its surface temperature immediately rose, effectively becoming a hand warmer.
"It's a pity I can't command the flying sword," Chen Mu thought regretfully.
After all, magic artifacts generally require corresponding Dharma curses to be activated.
He played with it for quite some time before reluctantly setting it down.
"I just hope the secret to operating the flying sword is within this ring," Chen Mu now felt somewhat uneasy.
