The death of Uncle Shu only the younger generation seems to mourn about it. But the generation older than they are upon hearing what their comrade did at his last breath made them feel at awe. It was good enough that he was able to badly injure the Undead King. If the bomb was just more powerful than the first one they can use what Uncle Shu did to kill that Undead King. Though this monster still didn't die, at least now they knew that he uses the ordinary undeads as dispensable to heal his wound.
The bomb maker was also from the older generation, that's why when he heard that the power of his bomb was insufficient to kill that monster, the Undead King. He once again tried to increase the strength of his bombs. However, he wasn't sad. He was delighted by the plan Uncle Shu had made. It gave them a way to kill the monster. Though it won't work the second time, it can be done through other means.
"Stronger explosion, smaller in size." The bomb maker said while doing his work.
