The business of Medicine King Valley spread throughout the Southern State.
However, the real Medicine King Valley did not allow outsiders to enter and exit at will, after all, precious herbs were planted everywhere within Medicine King Valley.
It was not only to prevent theft but also out of concern that too many passersby would damage the environment necessary for the herbs to grow.
Therefore...
Medicine King Valley made Chu County into the medicinal capital.
Any place wishing to purchase herbs from Medicine King Valley would need to go to Chu County to buy them wholesale.
Among them, Jishi Hall was a medicinal hall founded by Liu Rufeng, one of the three great eighth-rank alchemists of Medicine King Valley, and when Xiao Yi and his party arrived at Jishi Hall, he was attracted by the couplet at the entrance.
The first line of the couplet: "May there be no illness in the world!"
The second line of the couplet: "I'd rather let the dust settle on these medicines!"
