The Bargain Archmage 1

After awakening as a low-tier mage in a world where power is everything, Sean Shaw is dumped by his girlfriend and shunned by his team. But when his system suddenly lets him upgrade skills for just one coin, Sean rises from underdog to legend—crushing the Ninefold Tower solo, outshining his rivals, and surviving deadly ambushes with pay-to-win gear. With legendary loot in hand, he heads to the Ascension Hall, ready to face even greater challenges.
