Jacob let the One Fist team enter the sealed space first, and when they all went past the entrance, he took something out of his space ring. It was a TNT brick, and he started to set them in the tunnel!
Jacob has already heard half of Frugal's conversation with his father, and he knew trouble was coming. Although it was unexpected, now he had no choice but to take extreme measures.
The Star Hackers were extremely mysterious, and from what he could tell, Frugal and Aven were the children of some high-ranking members. So, destroying this pathway was the only option he had now.
But he had to do it discreetly since the One Fist was still useful, and he couldn't let them suspect him too early. So, after setting the TNT, he set a timer and finally entered the space himself.
