Gosh dang, Sei did some impressive s888 this chapter. The way he blocked the attack from the tree, then simultaneously saved Lillie with a soft landing and stopped the other courier dude by storing the air, then releasing it to push himself to kill the courier to stop him from taking the women, while prepping a soft landing for them AND protecting them by storing the earth from under them, then releasing it to stand vertically to act as a wall was amazing! The artist and author cooked with this chapter, ngl, which is especially surprising for an erotica.
I also like how this time, there were multiple elements that he had to take care of, and couldn't do it all himself, so he'll rely on each of the girls' specialties(Scarlet's fire against the tree, Zoffi's speed to catch Rock, Luna's healing to save Lillie) to get the job done. It won't even be him to get Rock, which is very surprising considering the main protagonist(ones like Sei anyways) is usually the one to deal the final blow to the main antagonist, which is Rock in this case. And he might still do so, but unless Zoffi subdues him after Sei helps Luna heal Lillie, it may not actually happen.
