After Surviving the SSS-Rank Demon Territory with a Useless Skill, I Became the Strongest Alchemist in the World ~Creating a Comfortable Base and Enjoying Life with Friends in Another World~ - Chapter 1

Not surprised by his sudden power up. Typical trope in isekai manga. It’s also the same plot where the MC is just tossed away for being “useless” because there’s always that scumbag which is summoned with him.

It’s too early to judge it, since there’s only a single chapter. But I personally don’t expect much other than cringe and cliches.
