John at this time was looking at the hordes of undead with an ugly expression on his face. As their numbers were overwhelming and during the night their power seemed to have increased.
He felt that if he couldn't come up with a new solution then he might face a disastrous defeat.
Jack at this time said in a loud tone," Master, those undead are getting harder to kill. If this goes on then we might be defeated."
Evelyn from the side added another layer of vines to prevent those undead from approaching.
John saw all of this and he couldn't help but say," Use the grenades to blow them all off."
As soon as he gave orders, the soldiers immediately threw. For a moment there was a huge explosion and it cleared a large number of undead. John's eyes lit up.
He suddenly remembered the sap plant. Although those plants were of ordinary origin, he remembered that once they were burnt then the fire would keep on burning, and it was hard to put it off.
