The phenomenon of bioaccumulation accelerates more and more in the mid to late stages. At first, large organisms could only accumulate Evolutionary Energy by devouring countless small organisms or absorbing Evolutionary Energy from seawater. But as these surviving small organisms absorbed enough Evolutionary Energy from the ocean and turned into large mutated organisms, the originally large organisms could directly devour these already-evolved large creatures to rapidly accumulate Evolutionary Energy.
This means that as time goes by, their evolutionary speed will become increasingly terrifying,
to the point that almost every day, their evolutionary rate will be several times higher than the previous day.
