Zhang Chunxiang has been quite distressed recently. Ever since the war with the Southern Heavenly Kingdom, she returned home only to be ordered to memorize various herbal information. Until she learns them all by heart, she's not even allowed to go out for fun.
According to her granduncle, this is the foundation for the Zhang Family's standing in the Great Cave Heaven. As long as they have this knowledge, there will always be a need for the Zhang Family, and they will never be cast out of the mainstream.
Being needed—these four words are extremely important in the Great Cave Heaven.
Because of the Secret Law, it's almost impossible to carve out a place in the Great Cave Heaven alone. Cooperation with others is necessary; otherwise, one will eventually encounter a Secret Law they cannot handle, leading to untimely death.
In such a place, the most useless people are often the first to become cannon fodder.
