Lightning gathered, and twelve weapons made of lightning appeared.
This time was different. Instead of shooting into the sky, the lightning weapons floated behind Werther.
Werther pointed his swords forward, and the twelve weapons shot out, taking up positions around Sengoku and the other three.
Werther leaped backward, leaving the Sword Grave's domain.
The weapons around Sengoku and the others suddenly blazed. Lightning spread from each one, and arcs of electricity soon linked them into a net.
Sengoku and the others had no intention of letting Werther do as he pleased. The moment the Sword Grave formed, all four tried to break out.
A crushing pressure descended around them. They felt like insects trapped in amber: no matter how hard they struggled, they could not leave the area.
Watching them struggle, Werther sheathed Intent Blood.
This was another use he had discovered for the Sword Grave. Rather than entering it himself, he could use it solely to trap his enemies.
Once the Sword Grave formed, it was extraordinarily hard to escape. No one but Werther could move freely inside it.
Even Werther had to expend a great deal of stamina to move freely within the Sword Grave.
He was deep in enemy territory and had no way of knowing how many foes remained, so he had no intention of getting bogged down fighting Sengoku and the others.
"What... is... this?"
Sengoku and the others stared in astonishment. They had never imagined Werther could develop a technique like this.
Werther did not answer Sengoku. He walked slowly past the Sword Grave toward Marine Headquarters.
He strode openly into Marine Headquarters, while the Vice Admirals could only watch.
"We can't let him go any farther. We absolutely can't."
"Then we'll fight him with everything we've got."
"Right. We can't let him through."
