This was the first time the Diamond Region had sent dragons to attack Liu Zhi's territory.
So there weren't many of them. Five dragons flew over in total.
Unlike the corpse dragons Liu Zhi had seen in the Underworld, these dragons were silver all over and full of vitality.
They weren't as stiff as the corpse dragons of the Underworld.
As they flew this way, they seemed reluctant to fly over the glaciers, instead following the valleys between them.
It seemed quite strange, but it worked in Liu Zhi's favor. The fortress city stood right at the mouth of one such valley, so as soon as the dragons appeared, they fell straight into the Spinning Fate Spider Woman's trap.
When the dragons attacked, the Spinning Fate Spider Woman was still studying how to make the silver-shell spiders more useful through reinforcement.
She had already noticed that these silver-shell spider troops had significantly improved defense and attack, but their upkeep had also increased considerably.
They had to be reinforced with the flesh of special silver-transformed creatures, which meant the silver-shell spider troops could never be very numerous.
At the same time, their shells made them heavier than the soldiers in a normal spider troop, yet they had gained little beyond their close-combat ability.
So converting them into Spider Cannons was a poor choice, and turning them into Spider Infantry wasn't much better.
Spider Infantry were meant to be produced in large numbers, but these silver-shell Spider Infantry couldn't be mass-produced.
So the Spinning Fate Spider Woman had simply started designing a new kind of spider soldier.
But none of her designs ever quite achieved what she wanted. Every batch of silver-shell spiders she made turned out to be awkward to use, and she couldn't figure out what had gone wrong.
