Having entered the instance dungeon located inside the subway, Jinwoo levels up time and time again by fighting waves of magic beasts. As he gradually makes his way forward, he finds a long stairway leading deeper underground.
And if I fight needlessly, 
the sword won't last.
.وإن قاتلت بدون داعٍ، فلن يصمد السيف
Das Schwert würde nicht
noch mehr Kämpfe aushalten.
Y la espada no aguantará
más peleas en vano.
Y no quiero romper la espada
con más luchas inútiles.
Et si je combats inutilement,
mon épée va lâcher.
Se perdo tempo in scontri superflui,
 la spada non reggerà.
E esta espada não vai durar
se eu lutar sem necessidade.
А продолжу драться просто так —
сломается меч.
