i become the strongest with infinite skills level

Ethan never expected to wake up inside the game he once played.
Tower of Ascension, a world where every adventurer fights their way up through endless floors, each more brutal than the last.

Here, skills define everything.
But all skills are capped at Level 100. No one can break that limit.

Except him.

When Ethan transmigrated, his system glitched.
His skills could rise infinitely.

[Congratulations, your skill level-up]
[Sword Swing Lv. 999+ — A single slash could shatter a fortress.]
[Fireball Lv. 999+ — An army reduced to ash in a breath.]

What began as a bug soon turned him into the tower’s greatest anomaly.
Guilds will hunt him. Kings will fear him.
Even the gods guarding the highest floors will see him as a threat to erase.

But Ethan doesn’t care.
If the world insists he’s an error, then he’ll climb to the very top and prove that even the Tower itself can’t stop him.
