Yes, the Bone Horseshoe Crab.
The reason there was a certain non-human element in that scream is precisely because it was too accurately replicated.
Of course, it wasn't because the wound healed so well that Fu Qian burst into tears of joy; at that moment, he was imitating the gift Professor Lisa had once given him.
The Bone Horseshoe Crab that she had hand-assembled and sent as a milestone research result.
Just pressing it would produce an ear-piercing scream, which had disturbed the public once before.
So why did Professor Fu disturb the public again?
Simply put, he missed her dearly after not seeing her for a few days and was just inviting Professor Lisa for a chat.
The seat was just too comfortable, he really didn't want to ask in person.
"I just knew it was you..."
And at that moment, the concept of telepathy was demonstrated; seeing Professor Fu lounging there despite ostensibly being out on a field study, Lisa showed no surprise, only indignation in her eyes.
