The Pinnacle of Swords

Before people arrived at his store, Tian Qiyuan created a large sign that read, "Those who have my desired materials may enter the store immediately. Those who do not have priority must wait outside until their number is called."

"There are jade slips with numbers on it beside this sign. Take the number in the front and wait for your turn. I will have at most 10 customers at a time, excluding those with priority and with my desired materials."

"Every customer will only be allowed one commission request in their lifetime."

"Fighting is not allowed near the store, or you will be put on the blacklist. Those on the blacklist will not be able to receive my service."

"Those with a jade slip may sell their slot, but others are prohibited from threatening those with a jade slip to sell. If you pressure or force someone to sell their jade slip, you will be put on the blacklist."
