Jack found the underground factory of goblin through the memory of the queen goblin.
It turned out that the goblin was a creature with a hierarchy. Some of them were leaders, while some were enslaved and worked hard all their lives in darkness.
As for goblin, the queen had long been used by Jack to be his dark slave, a member of the zombie army.
Jack walked into the underground factory. Goblin only worked hard and didn't notice him.
"If I subdue this army, I will become stronger!"
Jack looked at the group of goblins under the ground and said happily.
Through the memory of queen goblin, Jack knew that they also had a kind of technology, that is, they had a weapon that could restrict the warrior's ability.
Jack knew that he needed this technology, because, with his strength, he couldn't even rule the continent, let alone the coming demon group and zombie legion group.
