Half a year passed after that conversation before Atlas started learning alchemy. He found that the training his two masters gave him was too difficult to do in tandem with other things.
Only when his routine slowed down a bit and his lessons shortened did he finally set the time aside to accomplish his final goal.
The Formation Spark had been relatively ignored in these past years. Atlas was used to being a cultivator alone, so it was only natural for him to delay such learning.
However, it really did represent an amazing opportunity. Alchemy, Forging, and Formation Arts, all three secondary professions, were laid bare before Atlas. Unlike his other aspects, he did not need a teacher or master, as the information they could provide him with and more was already present in his head.
