Rabbit Rabbit's Fourth Rank

Within the bronze palace, Shi Yan was teaching Shen Shuibi.

"You can try creating a relatively small Abyssal Return. This is the method—it takes less effort." Shi Yan flicked a spell technique toward Shen Shuibi.

Shen Shuibi did not stand on ceremony and began reading it as soon as she took it.

Overcoming the repulsion between matter required
