Submissive and breedable

Just like when Theo distributed the chants to those disciples who advanced, each chant was different from the other, suited perfectly to the constitution, talents, and the general situation of his disciples. 

And it was the same right now. After all, while Theo could endorse the idea of replicating the training he did with Tiana but with Kaya this time, then doing so with the three boys of his student group…

'Yeah, there ain't no way,' Theo thought, repulsed by the idea that didn't align with his sexuality. 'And what's more… would that even work?'

There was a strangely low number of mentions of dual cultivation in all the books that Theo consumed. 

Given how easy it was to stumble on this effect, he expected it to be common knowledge… But as it turned out, it was such a basic area that no one bothered to even write it down in any of the scrolls.
