"Isn't it too late to talk about this now?"
Faced with the surrender and submission of the Mother of Ten Thousand Snakes, Noah did not accept it, nor did he let Her go, but he also did not swallow Her like he did with the Sun Snake, for he doesn't swallow everything he encounters.
The Sun Snake was swallowed because its power was close to His, which benefited His growth, but the Mother of Ten Thousand Snakes was different. Swallowing this Snake Mother would be a pure waste and burden, with no gains, so Noah preferred to suppress Her.
Noah thought and acted accordingly. According to his plan and assumptions, he prepared to capture the Mother of Ten Thousand Snakes alive and seal Her in the Dragon Realm, right under his watchful eyes.
Unfortunately, the Mother of Ten Thousand Snakes, although inferior to him in power and rank, was still an old epic snake with rich experience. Upon realizing the situation was hopeless, she exploded on the spot.
