Inheritance?
Ash looked at the Fangyuan Cicada on his shoulder. After Weiser voluntarily sent Fang Chan over, Yuanchan merged back with Fang Chan.
Logically speaking, after Ash became a Legendary Mage, he should have been able to subdue Fangyuan Cicada, the Four-winged Technique Spirit. But considering the situation with Whitedove, Fire Cat, and Blue Bird, these Divine Beings elevated by the Great Skill all developed strong resistance towards their mage master, so it's unlikely that the Fangyuan Cicada, transformed by the Great Skill, would have a friendly disposition towards its mage master.
As long as Fangyuan Cicada stayed with him, Ash had no need to forcibly subdue it.
Besides Fangyuan Cicada, more than a dozen Technique Spirits like Thousand Mechanism were also with Ash. Knowing her inevitable death, Weiser had no interest in taking these Technique Spirits to the grave, so she gave them all to Ash.
Not only that, Weiser even offered herself to Ash:
God of Silver Lamp.
