btw, can you explain more on this

In the context"特别是正常买卖中，标准的MLS的Inspection contingency给你可以来回再向卖方讨价还价的余地。作为买家，你可以利用这个条款尽量向卖方压价，因为这时候就算卖方不肯再减或者补太多，你也只要接受对方不让步的条款，这个合同就照样继续生效（悄悄话：这也是一个Agent不愿意告诉你们的一个对买方非常好用的条款。）。"

I don't quite understand this sentence"因为这时候就算卖方不肯再减或者补太多，你也只要接受对方不让步的条款，这个合同就照样继续生效", can you explain more?

Say, from inspection, the inspectors say the total estimate cost to repair is $8k, then, you ask the seller to lower the price by $8k, if the seller refuses, then, what is the next step, how 只要接受对方不让步的条款，这个合同就照样继续生效" if the buyer's goal is to lower the price by $8k?

thanks!
