Li Rui's instant kill of Train Flame King took advantage of the opponent's carelessness.
After all, he had been running just now, hardly making a move, so the opponent wouldn't take him seriously.
But now, after the unfortunate Train Flame King perished, the remaining two immediately became fully focused.
The Black Flame King let out a fierce howl, the golden-yellow flames on his body turned black, and the temperature surprisingly dropped, showing some kind of divine power unknown to others.
Meanwhile, the Delivery Flame King's aura changed, splitting into dozens of small Flame Kings, each true in form, each at the level of an Elite Monster.
The two mini-bosses in the Secret Realm were both equivalent to the level of the Demon Dragon Valley King, and now they were showing their true strength, quite formidable.
Li Rui himself was not too worried, he was only wondering if Duan Ling and the others over there could take down these two monsters.
