The duo held their meeting for a long time until eventually they covered all the issues Lex wanted to discuss. After that, Lex retreated to his cultivation room while Mary returned to her grocery shopping - if that's what she was really doing.
Lex resisted the urge to spy on her and instead focused on Lotus. He dedicated a portion of his mind to helping Lotus adapt to Regal Embrace, while softly channeling the feedback from his Primordial Dao Body back to Lotus to help it grow strong enough to properly and completely fuse with the realm.
The rest of his attention was towards Taro's journal. That thing held secrets the existence of which Lex could not even comprehend because he lacked the knowledge to even imagine the foundations and basis for their existence. That was not such a reflection on Lex's ignorance as it was a reflection of Taro's genius, for he was the foremost expert in developing realms.
