What nonsense is this! When have you ever seen a monster onion learn something akin to 'super regeneration'?! Only lizard or earthworm-type monsters can perhaps learn such a skill!
Lady Onion really wished to spurt her green onion juices on Yu Jiaojiao's face at this time. It wasn't a super regeneration ability; it was more like peeling her skin off. They had directly peeled the green onion sprouts off her body!
The pain she felt caused her green onion juices to flow out.
Nevertheless, although she'd felt a lot of pain earlier, she felt rather good now. When her newly born green onion sprout danced in the wind, Lady Onion could feel a cool and refreshing feeling getting transmitted to the rest of her body.
To make an example, it was like having a decayed tooth that was rotten to the root extracted. During the extraction process, one would feel great pain, but they would immediately feel better after the dentist was done taking the tooth out.
