章 626: Tower Defense Game

Within the time they spoke, Holy Knights had already reached the end of the battle line. Wild Thunderheart, who was at the most front of the ambush, swerved his staff and shouted, "Attack!"

After Wild Thunderheart ordered, the Guardians moved into the Shield Formation then charged towards the piles of rocks beside the cliff which they built a while back.

Once the piles of rock were pushed by a collective effort, they started to roll down the cliffs.

The cliff was only eight to nine metres wide. For a cliff so high, the road was too narrow such that when the large rocks rolled down, they would bounce against the mountain, and rain down randomly, smashing into the holy knights below.

Although the Holy Knights were top elite level 60 monsters, had the hundreds of thousands of HP, and were dressed tightly in metal armours, the damage done by these falling rocks were shocking. Once hit, they could not avoid broken bones.
