The big black snake had a very sturdy body with higher strength and vitality than Apep. But Apep was more flexible, had better stamina and was much quicker than this big black snake.
So she was definitely not on the losing side of this battle. And with enough time, winning should be very much possible for her.
But time was the exact thing that Weiss currently lacked with the worsening condition of Alexis and Frank. So she decided to end this battle as soon as possible.
Weiss secretly took out a small needle. Before such big beast, it looked like a joke. But actually, it was something super effective.
This needle was coated with a special kind of poison that Weiss herself had created. Obviously she had researched poisons too and not just potions. And this poison was supposed to be super effective on any and all kind of snake type monsters.
