Despicable Method

If they were released, chaos would engulf the entire world! 

What made it even more terrifying was the prospect of the bronze door swinging fully open. 

Once the spirit beasts within the ruins spilled out into the world, it would plunge everything into turmoil. 

People who had known nothing but the comfort of prosperous cities since birth had never even done the simplest tasks like slaughtering a chicken. 

Most young women wouldn't even dare to attempt it!

To expect them to handle spirit beasts? 

A mere first-level spirit beast, even at the lower end of the spectrum, could potentially massacre tens of thousands in a single night. 

Those of third-level or higher could effortlessly wipe out entire cities overnight! 

A ninth-level spirit beast could lay waste to a small country without breaking a sweat. 

Hence, the bronze door would remain firmly shut to them, no matter how prolonged the war became.
