At the fortress city in the south of the kingdom.
That was the kingdom's southern border. A long wall stretched across the border; the wall was at least a hundred meters high. Both sides of the wall were fused with the wild and primitive forest. On the wall, some vines had been soaked in a special potion. Once activated by magic, those vines could grow wildly. Those vines could be used as a defensive network, or they could be spread out and be used as offensive weapons.
However, most of the vines on the city wall were spoiled, spraying out green juice. Some were even burnt black by the flames, breaking and squirming on the ground. Not only were the vines broken, but even the city wall was also damaged beyond repair. Large holes appeared on the wall. The bodies of soldiers and broken weapons hung on the wall, appearing to be in decline.
