There's "farming in a tower" It's like this but he's an op farmer.
You'll know that you have found it when you see the MC jump into a rift to go into the tower that is run by a female dragon and he becomes a tower farmer for said dragon alongside cute farmer Rabbits. Expect alot the fuffies over time.
There is also "I log in alone."
i already read farming in the tower and it's really gooddd, but not i log in alone so thank u so much for the recom !!!
can someone recommend me similar manhwas like this one? where the mc is smart but also dumb at the same time, just like the mc here haha
