According to Senior Scarlet Heaven Sword's speculation, if someone wanted to scan this QR code and add Song Shuhang as a friend, the premise was that they had to be connected to the Dragon Network of the Black Dragon World.
Only after you had connected to the network would you be able to access the friend adding function of the QR code.
But between Song Shuhang and Sage Monarch Melon Eater, there was the 'Virtuous Network' in common.
So the question was—did the Virtuous Network work the same way as the 'Dragon Network'?
Through the Virtuous Network, would Sage Monarch Melon Eater be able to add him as a friend?
Song Shuhang was very curious about this. He wondered what would happen if Senior Melon Eater scanned the QR code.
As such, he projected his QR code, and decided to try it out.
