As Lizzie was about to give the killing blow to the Silverback gorilla, Jiang Song instantly teleported in between them and stopped the attack. "Alright, Lizzie. That's enough for today. You won the match and here's your reward." The Zoo Guard said as he took out a slab of juicy meat, possibly beef and tangled it in front of the Brown Bear.
Obviously, Lizzie isn't a human who can make rational choices but since Jiang Song was dangling a piece of delicious smelling cooked meat right in front of her, she could not resist it. Thus, she walked away from the Silverback Gorilla and started consuming the meat in peace. And just as she was about to finish chewing the first one, a portal emerged right in front of her and Jiang Song threw another large slab of meat through it, hinting her to return to her environment.
