Kage had awakened in a new world. He tried to summon the soul system that had been with him since his own world and belonged only to him, but he shouted 10 times, 100 times and the system heard his voice and woke up.
When the system is turned on, Kage's information appears as follows: Name: Kage, Strength: 4, Agility: 6, Mana: 1, Profession: Necromancer, Level: 2. When he saw his mana value, he tried to improve his mana so that he could summon like before, but his body was dead. Because of this, he could not assimilate the meanings around him.
He searched the buildings for mana pots to summon, but couldn't find them. He tried to become stronger by defeating other weak zombies. As he spotted a hiding zombie, he shouted "I'm not like them" as he attacked and the Kage stopped his punch. Kage found a zombie who spoke like him and asked him about this world.
Zombie explained that this world used to be a war-free and happy planet, but due to a virus that suddenly appeared, zombies multiplied very quickly and countries fell one by one within a few days. Zombies ate all the humans and there were no humans left alive. The zombie took Kage to the underground city where talking zombies lived. Kage asks the zombie "Have you ever heard of mana and hunters in this world?" she asked, but she said she had never heard those words before.
While they were wandering around the city, they saw a tournament and they were giving out power stones as prizes. Kage asks the zombie "What are the stones for?" he asked and the zombie said that every zombie has a stone and that he can develop the stone inside him by eating those stones. Kage registered himself for the tournament. Kage registered for the tournament and bought 2 daggers from the city with the money he earned from the zombies he killed before.
The tournament has begun and Kage begins fighting rival zombies. His first opponent was an easy match and Kage won comfortably. His second opponent was stronger and more experienced. Using his daggers, Kage gradually injured and eventually killed his opponent. His third opponent was a very strong and tough opponent. As the tournament progressed, he started to encounter stronger and tougher zombies.
When he came to the final match, his opponent was a Stage 2 mutant zombie. Mutant zombies had evolved because they were stronger and lived longer than normal zombies. Kage had a hard time in the final match. His opponent was constantly attacking him and could not wound him with the Kage's daggers. Kage used his agility to evade his opponent's attacks and occasionally counterattack.
However, despite being injured by the Kage's daggers, the mutant zombie was still standing and continuing its attacks. Kage finally used his opponent's strength to knock him down and plunge his daggers into his opponent's head. Kage won the tournament and the host gave him the power stone.
Kage ate the stone and increased his strength, his current strength is five times that of normal zombies. However, he needed to find the blue stone to increase his mana.
