Give junior sister a high-grade Tongmai Pill, which will trigger a hundred times critical hit and return it, and you will get a hundred high-grade Tongmai Pills!" "Ding! Give junior sister a top-grade Ganoderma lucidum, which will trigger a thousand-fold critical hit and return it, and get the holy medicine Poria Goddess Chi Yuanzhi!" "Ding! I will give my junior brother a Xuan-level magic weapon, which will trigger a 10,000-fold critical strike return and obtain the ancient artifact Xuanyuan Sword!" Senior brother, don't give it away! There are already enough opportunities for us to take advantage of.
