Location: Swamp plane, 3,000 crypt spiders, they are the team of the undead legion who was selected by the undead triumvirate to explore the source of the poisonous fog, and their mission is only one way, that is, to go down, down to the depths of the underground that constantly spit out dark green poisonous fog in the memory of the queen ant, to find out what the source of the poisonous fog is!

The reason why the crypt spiders were sent instead of ghouls this time is also because they need to climb deep underground, so if they send ghouls, then it's hard to say that they just roll all the way down, so it's better to send the same huge number of cave spiders who are good at burrowing and climbing.

And with Anubrak's order, the 3,000 crypt spiders did not hesitate to line up in a neat line to explore the source of the poisonous fog underground, but first they needed to reach the front of the cave that would emit dark green poisonous fog.

Although they have the memory of the queen ant, in fact, the undead still don't know the specific location of the burrow, after all, the ants don't give each place a name to remember the way, so although the queen ant has seen it, but it can only let the undead roughly know where it is, but not let the undead know where it is, so the task of searching is also handed over to the 3000 crypt spiders.

It is precisely because they still need to find the hole that the three giants will decide to send 3,000 crypt spiders after discussion, otherwise sending 100 will be enough!

Half an hour later, a burrow spider found a half-buried hole in a half-collapsed tunnel.

The entire half-collapsed tunnel is full of corpses of various creatures, as well as full of turquoise, the feet of the crypt spider are just stepping into a quagmire full of water and grass, and countless poisons show a thick liquid covering the entire tunnel space, even the crypt spiders who have just stepped on this tunnel are instantly dyed from gray to green by the terrifying toxins here, but fortunately, the undead are turned into corpses, so I have never heard of any poison that can poison the corpse.

But this is not the most interesting point, the most interesting thing is that after the crypt spiders were completely dyed green by the poison, their bodies changed, they became highly poisonous crypt spiders, a kind of turquoise crypt spiders, a kind of crypt spiders that can spray terrifying corpse poison, and at the same time, the webs they spit out are also highly poisonous, even if they die, they can have a venom explosion similar to StarCraft poisoning bugs at the last moment.

However, this is not the point, because the real focus is on the task assigned by Wang Fan before leaving: exploring the source of the poisonous fog is the top priority, and the others are ranked behind this matter, just because this is an order given by Wang Fan.

Of course, it's not completely unconcerned, after all, something like this that can improve the combat effectiveness of his combat group will still make all commanders dream of it, so in a gap time, Kel'thugad issued a transformation order, ordering 700,000 crypt spiders to enter this underground tunnel in batches for highly toxic transformation, intending to transform this class that has begun to be a little out of step with the times into a higher level of troops.

As for the troops that can't keep up with the times, the undead never need the weak, and the order of the undead is to absolutely obey the orders of the higher undead, even if they are allowed to die. (Of course, when the wise undead encounter their superiors and let themselves die, then they will be passive and sabotage, so it is generally difficult to die)

The first to enter the Poison Mist Crypt were the vanguard of 1,000 crypt spiders, who slowly entered the tunnel in a long line along the slippery surface covered in thick venom towards the half-hidden hole at the end of the tunnel.

At the same time, I, the three giants, also focused their eyes on this vanguard army, and the three of them successively connected their spiritual power to the bodies of the three crypt spiders through attachment, and carefully observed the world under the poisonous fog cave through the eyes of the three crypt spiders.

In fact, there is not much difference from the above, it is all dark green high concentration viscous venom everywhere on the ground, but because there is not much air circulation, so here is a suffocating oxygen-free environment than the ground, fortunately, the exploration team that came in is full of undead who do not need to breathe, so in this terrible poisonous fog cave that can make most creatures die in an instant, the crypt spiders continue to walk towards the lower place unscathed.

But the next journey began to completely attract the attention of the three giants and even Wang Fan, because they saw some strange things from some corners of this cave, and the three giants were surprised by this curiosity, so that the crypt spider picked up these things, and then called the master Wang Fan.

And the reason why it is so surprising is that this strange thing is a stone axe that has not been polished!

This is not the elf plane, this is the swamp plane, so Wang Fan and the Big Three did not expect to encounter the tools left by intelligent beings, although this tool has been abandoned for a long time, and it looks like the years and textures on it have been decades to say the least, but it still surprised Wang Fan.

Then Wang Fan conducted a carpet-covered search of the entire area for this purpose, and they really found a lot of evidence that could indicate that there were once intelligent creatures here, such as some animal bones that had been obviously roasted, and some traces of artificial excavation on the rock wall, but after comparing the stone axe in his hand, Wang Fan denied the argument that the other party used the stone axe to dig a slotted cave, just because the traces on these rock walls are more like tunnels dug directly by countless pairs of claws!

Wang Fan is also very interested in this! Although he has secretly actually controlled the small elf tribe now, and he can see those elves who are very good-looking every day, this cannot make Wang Fan satisfied, after all, in the novel game of his previous life, dwarves, orcs, Goblins and so on are all very distinctive, so Wang Fan wants to see them, since some ruins of civilization have been found here, so even if they can be said to be almost certain to be dead, Wang Fan still can't help but be curious to see what kind of race these races have developed civilization on their own without anyone's help.

So the fourth crypt spider is possessed!
