Batman's super Bat-Memory Reader was not entirely his own invention.
The device had originally been invented by Lex Luthor as an advanced brainwave lie detector. After the Justice League seized it, Batman dismantled it, figured out its principles, and went a step further, creating a far more powerful version based on it.
It was like someone buying a Xiali, taking it apart to study it, then building a supercar from scratch with their own hands.
They were both cars, sure, but whether the latter had any direct connection to the former was debatable. In any case, the memory reader belonged to Batman, and Luthor could forget about claiming the intellectual property rights.
As Batman performed cranial surgery on Christopher without even administering anesthetic, Deathstroke and Dream of a Thousand Cats appropriately began eating tofu pudding. The man and cat were currently inside Harley's dream, slurping from the edges of their bowls together.
Ordinary cats would stick their heads into a bowl and lick at the food, so Dream of a Thousand Cats holding a huge bowl in both front paws and drinking straight from it looked rather adorable.
"The human brain really does look like this bowl of tofu pudding." Batman was currently peeling back the patient's dura mater and using a vacuum tube to suck away the flowing blood. Seeing this, Kitty meowed, "Slade, get me another bowl, meow. This time, I want sweet tofu pudding."
It had just eaten chocolate cookies and found them too dry, so it was pairing them with tofu pudding.
"Heh heh, sure. A sweet bowl coming up." Su Ming rubbed Kitty's ears and indulgently conjured another fresh bowl for it. Though he was from the north and accustomed to savory tofu pudding, he did not consider Dream of a Thousand Cats' preference heresy
