Kage won the tournament and received the power stone. However, he still needed to find the blue stone to increase his mana. So, after the tournament, he started searching around the city and talked to other zombies, but he couldn't find out where the blue stone was and how to find it.
Kage put a lot of effort into finding the blue stone, but he finally managed to find it. The blue stone was right in the middle of where the Stage 2 zombies lived. He gathered his courage and set out to find it.
In the danger zone, he faced powerful and experienced mutant zombies, but Kage was able to defeat them with the power given by the power stone and his daggers. Finally, he reached the place where the blue stone was located. Kage faced the Destroyer zombie at the place where the blue stone was located.
This zombie was much stronger and faster than the others, it could destroy everything it touched. Kage gathered his courage to grab the blue stone and began fighting the Destroyer zombie. Kage slowly injured the zombie with the power of the power stone and his daggers, but the Destroyer zombie was still healthy and strong.
The zombie easily dodges Kage's attacks, causing Kage to sustain injuries. Kage began looking for tactics to reduce the zombie's power and discovered its weak points. Kage targeted the zombie's arms and legs and cut them off, slowing the zombie's movements.
Kage gradually destroyed the zombie by reducing its power and was able to get the blue stone, expecting its mana to increase after eating the blue stone, he was disappointed. He still couldn't summon and the lowest summon required 10 mana. Kage had 5 points. In this case, Kage would defeat more powerful zombies and look for more mana pots to increase his mana.
He would also talk to other zombies to gain more information as he moved around the city. Kage would do anything to summon and obtain the mana points needed to summon.
