Ye Mei finally understood what he meant by a substitute.
Humph, had I known, I should've listened to Grandpa last night.
Why did I have to be so stubborn?
Now look, I have to let him take advantage of me again.
Ye Mei wanted to cry but held back her tears, not willing to let Ye Fei off so easily.
"Master, I am not pregnant, and I certainly don't have what you want."
Hearing this, Ye Fei spoke seriously, "Ah, one should never give up without trying. How can you know it's not there without a try?"
After speaking, Ye Fei pushed aside the last barrier directly before him and buried his head in.
Ye Mei, with tears threatening to fall, could only tilt her head back and bite her lip as she stared at the ceiling.
After much effort, Ye Fei still didn't get what he was after.
He lifted his head, still unsatisfied, and said irritably, "Ah, indeed, experiment is the sole criterion for testing truth."
