Ludwig looked at her then contemplated. Regardless of everything, it was indeed tempting. If he were to do that, he will speed up his cultivation by a lot. Although there wasn't a particular pressure behind him, he somewhat was dissatisfied with his progress currently. It was like telling an adult that he wasn't allowed to sit on the table for adults.
He behaved pretty much like a senior in cultivation the whole time he acted, if he were to advance forward, then this behaviour wouldn't seem awkward at all. But these are all only second thoughts, when he looked at Nyx, he still wasn't sure, so he wanted to wait. He would ask her directly if he could, but Nyx herself didn't seem to think of what he was thinking at all, so he'd rather wait and see her act before he asks her.
Still, this was all a good situation so he nodded towards Nyx and agreed "We can do that indeed, I am somewhat in need of cultivation resources."
