By the time Li Nanmu had recollected himself, he started laughing out loud. "I can't believe you used to be one of the smartest students. You can't even get basic Mathematics right. An 80% discount is four million, you fool."
"Oh!" Gu Nianshen nodded patiently. "Four million it is. Pay up."
Gu Nianshen extended his hand to Qi Wuyue and Li Nanmu.
"..."
Li Nanmu and Qi Wuyue felt that there was no way out of this. They could not think of any excuse to reject Gu Nianshen.
"Even if I must pay, I will pay to Lin Yiqian on my own. At least we would have done something good on our own account. Why should we let you take credit for it?" Qi Wuyue finally snorted.
"Fine." Gu Nianshen retrieved his hand as he straightened his back. "You may leave now. The goods will be delivered to your address by this afternoon."
Then, Gu Nianshen turned to his laptop and ignored the two men completely.
