Su Yang replied nonchalantly, "Even if this is from the year 1888, it still has nothing to do with me. What I'm reading is the book, not its era."
The old man glared at Su Yang. "70 yuan. I can't go any cheaper."
Su Yang had turned around and was about to leave.
However, the old man quickly stopped him. "Come back, come back here. 20 yuan! The lowest is 20 yuan! This really is my cost price! I'll sell it to you for 20 yuan!"
Hence, Su Yang took out a 100 yuan banknote from his pocket and passed it to the old man.
However, the old man did not take it. Instead, he picked up a sign. "Do you see this? WeChat and Alipay are both accepted. Please pay without contact, let's make all of us happy."
Su Yang was speechless.
'Tsk, this old man is quite trendy.'
Hence, Su Yang transferred 20 yuan to the old man and got into his car.
