Global Extreme Cold and Natural Disaster, I Will Win with My Cubs

Did the heroine suddenly become wise? When killing zombies before, it was useless to insert the heart, and then insert the head to cut off the mobility. This description means that the heroine didn't understand anything and reluctantly accepted this stupid setting😓 But now she clearly knows that the corpse will mutate and does not attack first to destroy the life of the head before throwing the corpse away... Also, is it stupid to choose to throw the corpse out of the window instead of killing the bad guy directly? Or is it for the plot? Deliberately creating more zombies 🧟⋯⋯ I hope the author will not make the protagonist smarter 😓 Otherwise it will be difficult to continue watching 😓
