Zhou Yuwen had discovered a treasure in the basement of a castle abroad before, but due to the distance, he never considered bringing it all back to the country. He only brought a few small items, intending to have them appraised by professionals. As for how much they're worth, it all depends on the buyer.
Zhou Yuwen couldn't come up with thirty million in cash, but if he takes this gemstone to an auction in Europe, it would surely fetch more than thirty million.
So when Zhou Yuwen suggested using the gemstone, Tao Tian opened her mouth but in the end didn't say anything.
Zheng Yanyan, who was initially most worried about Lu Lin, also hesitated upon hearing that Zhou Yuwen wanted to use the gemstone to trade for Lu Lin.
