What did the king of Qin say to 15 when he returned to Zhao?

It shows that the King of Qin doesn't really want to give fifteen cities to Lin Xiangru, just to get the city walls.

The main contents of One Piece Returning to Zhao:

Zhao has a beautiful piece of jade called "He Shi Bi". When the king of Qin heard that he wanted this jade, he sent an envoy to see Zhao, saying that he wanted to exchange the city for this jade. The king of Qin has always been insatiable. The king of Zhao knew that he was just trying to cheat He Shibi, but because of the strength of Qin, he dared not refuse directly, so as not to start a war. Just when he was embarrassed, Lin Xiangru stood up and claimed that he had a way-either to change back to the city or to bring He Shibi back to Zhao completely.

In the state of Qin, the king of Qin was really only interested in Bi, and said nothing about giving up the city. At a meeting, he wanted to seize the jade by force. Lin Xiangru vowed to die. He grabbed He Shibi and prepared to hit the wall and threaten the king of Qin: either exchange land and the city for jade; Otherwise, he will hit the wall, and the king of Qin will get nothing and be reviled for his treachery!

Although the king of Qin loves beautiful jade, he is not fatuous and unwilling to change land. It is worth letting Lin Xiangru take He Shibi back to Zhao.
