This was why the Water Spring Secret Realm had been opened to them. Water Spring Crystals were simply too difficult to mine; with Water Spring Worms guarding them, out of every ten people sent in to mine, only one could make it back.
And even that sole survivor might not necessarily be able to bring out any Water Spring Crystals.
More importantly, the Water Spring Worms would occasionally descend into a frenzy. Once they did, they would move across the entire Water Spring Secret Realm on a massive scale.
The whole Water Spring Secret Realm would be shrouded beneath the shadow of the Water Spring Worms. At such times, anyone who dared show their head would inevitably be surrounded by them.
"Uh, according to the intelligence gathered by the Imperial Dynasty, once the Water Spring Worms go berserk, it lasts for an entire month."
The young man behind Xu Feng said anxiously.
Xu Feng grew even angrier upon hearing this.
"Damn it, the frenzy lasts a whole month. Are we supposed to do nothing for that entire month?"
"Besides, this Water Spring Secret Realm is only open for one year. Wasting a month just like that would be one thing if we'd found Water Spring Crystals, but the problem is that I haven't even seen a single Water Spring Crystal before getting trapped in here."
"Fucking bad luck."
Xu Feng sat on the ground, cursing furiously, yet there was nothing he could do.
Because he had no way whatsoever to deal with the Water Spring Worms.
The Water Spring Worms were impervious to all methods. No matter what means were used, they could not be killed.
As for trapping them with something?
Wishful thinking. The teeth of the Water Spring Worms could bite a hole even through a Limitless Artifact.
