What's under the plague whirlpool?

Before entering this vortex earth cave, Tang Dou thought of many possibilities, whether it was an underground castle inhabited by the black dragon of hell, a magical and spectacular underground world, or a dark gate to the demon world.

But it was clear that he was overthinking.

Underneath the earth cave is an underground magma passage that has already solidified its shape. This can be seen in the molten solidification on the four walls of those passages. Walking into the depths for about half an hour, Tang Dou still smelled a faint smell of sulfur in it, which indicated that there might be a magma lake at the end of these passages that had not yet been extinguished.

"The smell, could it be that these passages lead to geothermal rock lakes?" Tang Dou was not the only one who knew how to do it, Cheng Da opened his mouth with a little doubt.

"Geothermal rock lakes? What is it? "But more people still don't know what magma is.

Cheng Da explained what a magma lake is in the way of the Thousand Souls Spirit Realm: "It is said that under the earth where we live, a place so deep that we can't reach it, is a blazing sea of fire, and the temperature of this sea of fire is so high that even the rocks will melt into liquid. Occasionally, these seas of fire and lava deep in the earth will rush to the surface for unknown reasons, forming flaming mountains, but more often than not, they will hide in some deep underground caverns, forming geothermal lakes, which are hot lakes of water condensed entirely from melted rock. I once heard my teacher say that before he came to the Fog Hidden Continent, he entered a geothermal rock lake under the most famous flame mountain in the Barbarian Yuan Continent, and that time he entered with ten people, but only two of them came out in the end. Half of the ten of them are gold-level! ”

Except for Tang Dou, everyone gasped.

Volcanic eruptions rarely occur in the Thousand Souls Spirit Realm, and earthquakes occur only in a few areas. So not many people know about magma. As long as it is human, there will be an instinctive fear of the unknown, which has nothing to do with whether or not you have courage. It's instinct at all.

"Listen to you, you haven't been to Geothermal Rock Lake, why do you know?" Yun Zhen asked curiously.

"I really haven't been, but my teacher told me in detail about it and said that there was a demonic smell that I will always remember. It's the same taste now, if you spoil the egg-like taste! Cheng Da swore with the faint smell of sulfur in the air as a guarantee.

Everyone is not mediocre, they just didn't care at first, but now that Cheng Da mentioned it, they naturally discovered that special taste.

"In that case, it would be great, you tell me carefully, what do we need to pay attention to?" Warren asked solemnly.

Everyone came all the way, supporting and helping each other when fighting, and the relationship between these gold-level masters has become quite harmonious, so they talk more casually, and they don't need to think about what to say, just say what they say directly.

"Indeed, in a place like this that we have never been before, we really need an insider to provide experience!" The always serious green leaf * Mu Feng also nodded in agreement.

But Cheng Da just shook his head in embarrassment: "I'm sorry, my teacher at that time didn't enter the deep underground cave that they entered, so his experience may not be useful here." The only thing I can say is that geothermal rock lakes emit toxic gases, and that a lot of the seemingly solid ground in its vicinity is actually quite fragile, and one of my teacher's companions was standing on a hard-looking ground and suddenly fell into it! ”

Everyone sighed with some pity, not to blame Cheng Da, but to pity that there was no more experience to offer. If Cheng Da didn't know anything, it would be fine, everyone would just touch the stones and pass the road together, but Cheng Da knew a little, but it was not comprehensive. This is like everyone crossing the river together, Cheng Da said that the river in front of him is quite dangerous, but he can't say where it is dangerous, which makes everyone entangled.

"Geothermal Rock Lake Tourism Precautions 1: Keep quiet and cautious at all times, ensure that any movement in the passage can be found at the first time, but no matter what happens, be calmer, the more panicked, the faster you die!"

Just when everyone was entangled, Tang Dou spoke. He triumphantly held out a finger and began to play with himself.

Seeing everyone's eyes gathered, he stretched out a second finger: "Geothermal Rock Lake Tourism Precautions 2: Any gas, whether white, black, or yellow, cannot be directly touched, and it is very likely that there is a corrosive acid poison in it, or other poisonous gases that are directly fatal." At the same time, it is advisable to wear a gas mask at all times throughout the process! ”

Everyone's eyes became more and more surprised, and then Tang Dou continued to explain one finger at a time!

"Geothermal Rock Lake Tourism Precautions 3: As Cheng Da said, any foothold must be confirmed again and again, especially the closer to the geothermal rock lake, the more careful. Because geothermal rock lakes are the most likely to form hollow bridges, a layer on the surface that seems to be very hard, but in fact is very brittle, will crack when you go up with one foot, and then the whole person will fall into the high-temperature magma of more than 1,300 degrees, and even except for the fire soul cultivators or demon beasts above the gold level, others will have no chance to survive if they fall! ”

"Geothermal Rock Lake Tourism Precautions 4: Magma, that is, those melted rocks, have considerable viscosity, once they are glued, it is difficult to get rid of them, if anyone is unlucky to stick to it, if it can't be shaken open with soul power, then the best way is to break the wrist of a strong man!"

"Geothermal Rock Lake Tourism Note 5: This is also the most important point, geothermal rock lakes are not calm, and they are likely to erupt suddenly at any time. Everyone knows about ground movement, and often where there are geothermal rock lakes, there will be ground movement. Even if this kind of ground movement is hardly any threat on the ground, it is underground. Let's look around, if because of the influence of ground movement, the number and weight of rocks around you can be squeezed in an instant, who do you think will survive? ”

Tang Dou finished talking about some precautions that the tour guide said when he went to Iceland to see the volcano in his previous life, plus some content he added on the spot according to the reality of everyone, and finished talking about his five "geothermal rock lake tourism precautions", and then looked at everyone with a smile.

"Nicholas Owner, you, have you been to Hot Rock Lake?" Cheng Da looked at Tang Dou dumbfounded.

There are very few volcanoes in the Thousand Souls Realm, and even fewer places that lead to underground lava lakes. So few that many people don't even know what magma is, in such a situation, Tang Dou can actually speak so meticulously, how can it not be shocking?

"Well, I've been to one or two of those!" Tang Dou waved his hand very stinkyly.

I've only been to Iceland before, but I still have to take advantage of it, right?

Everyone immediately threw a look of astonishment at Tang Dou. No way, no matter what world it is, the kind of person who has done something that most people can't do, and has never even heard of, will be stared at like this.

"That's it!" After Tang Dou was proud enough, he clapped his hands: "I'll tell you what I think." Let's discuss! I mean, all the Silver tiers stop here, then defend in place here, wait for us to come back, and if anything happens, you guys have plenty of time and strength to get back to the surface. And the rest of the gold level went deeper with me. ”

"Master Nicholas, do you mean that the next road can only be guaranteed by the gold level?" Ling Chong asked, did she remember what Cheng Da said just now, half of the ten-person group was gold-level.

"This is one aspect!" Tang Dou nodded: "The further down, the worse the environment, and the more dangerous the emergency." I've never been here, and I don't know if what's going to happen is what I guessed, but I don't want to joke with everyone's lives! In addition, the closer you get to the geothermal rock lake, the worse its environmental stability becomes, and there are too many of us, even if we walk, we can get out of trouble directly, so I need to reduce the number of people! ”

Speaking of this, he paused for a moment and looked at Yun Zhen: "Speaking of which, I remembered it, Yun Zhen girl, I think you can stay!" ”

"Why?" Yun Zhen puffed up his way.

Facing an underground lava lake that she had never seen before, or even heard of before, you could imagine how curious Yun really was, but at this time, Tang Dou didn't let her go, of course she would be dissatisfied.

"Because your abilities are suitable for positional warfare, not raid warfare. You don't think we're the only ones down here, do you? Think of the peculiar living dead we encountered when we came to the plaguelands, and since we all decided that they were artificially modified, where do you say these people are? Could it be here? ”

Tang Dou's words made Yun Zhen speechless, so he had to say sullenly: "Okay, okay, I'll stay!" ”

"I'm here too, and my abilities are also suitable for positional warfare!" The green leaf * wood wind took the initiative to stay. She is a wood elf, and she specializes in ranged attacks and positional strangulation, and she really doesn't react as well as others in this limited environment.

With the green leaf * Mu Feng with him, everyone also suppressed their curiosity, and in the end, only Asuka and Mo followed Tang Dou among the five beauties of the Phoenix Immortals, and the other three stayed.

At first, Lin Xiao, who wanted to follow Tang Dou, also knew that he was not willful, so he obediently stayed. Of course, the Bright Tiger also stayed, and its auxiliary and healing abilities were extremely important, and it must be left in the large army to play a greater role.

In the end, the only demon beasts that followed Tang Dou were Ah Bao and Xiao Chunzi. In terms of personnel, the elves only sent a gold-level this time (it is really the strongest ordinary troops, so they only sent green leaves * wood wind)

, naturally no longer follow. On the demon clan's side, Warren and Maggie naturally have to follow. On the human side, although Lingchong and Kakuki are not experts in positional warfare, neither of them is suitable for going down. The former's attack is similar to that of Impatiens Flower Ji, and it is fought by operating demonized plants, but even if it is a demonized plant, there are very few that can fight in an underground magma environment, and Lingchong will not control it. Jiaomu didn't have a problem with combat effectiveness, but the key was that he was a half-elephant clan, and he was too burly, Tang Dou was afraid that this big man would go down and directly collapse the passage that could have passed, so he had to let him stay.

So on the human side, only Flying Bird, Mo, and Cheng Da followed.

After finalizing some arrangements with the people left behind, Tang Dou set off with five people and two beasts - strictly speaking, there is another one, the shadow girl has been following Tang Dou, but unless Tang Dou is in danger, or Tang Dou's direct order, the shadow girl will not come forward at all, except for Tang Dou and Lin Xiao, no one else knows about the existence of the shadow girl, so it is generally not counted.

After Tang Dou and the others left, Yun Zhen sat down with a depressed face: "It's a pity." What a pity! ”

"Don't worry, wait until Master and they find out below. If there is no danger, we can go back later! Lin Xiao was quite open-minded.

Yun Zhen's eyes lit up: "Yes, why didn't I think of it?" Well, that's it! ”

Everyone is sweating, what do you mean by being so decided, is it really so casual when you have a good relationship with Nicholas? But looking at Lin Xiao who nodded together on the side, everyone was indifferent. When they were on the road, everyone had already seen that Lin Xiao didn't seem to be big or small to Tang Dou, but this was the reason why Tang Dou loved this apprentice quite much. If things are really as Lin Xiao said, she goes to talk about it, can Tang Dou disagree?

Everyone has curiosity, so everyone is concerned about this matter. Whether it can be achieved or not, at least there is hope, isn't it?

On the other end, Tang Dou continued to go deep down with a group of gold masters, because he didn't dare to slow down too fast, he walked for more than an hour, and finally arrived at a relatively large underground cavity, and when he arrived here, the smell of sulfur was already so strong that it was pungent, if there was no filter of rune masks, only soul cultivators above the silver level could be active here for a long time.

On the other hand, the temperature has also risen to more than 40 degrees, and it is obviously not a place that ordinary people can withstand for a long time.

"The air here!" Tang Dou felt it: "Do you feel it?" Although the air here is very smelly, except for these smells, it does not have the dull air circulation of the normal underground, but it is obviously impossible for the passages we have passed through before to have such a large amount of air circulation! ”

Although everyone didn't understand any aerodynamics, the simple truth was still understood by Tang Dou as soon as he said it.

"So, there must be something here that keeps the air moving? Looks like we've found those guys' strongholds. Maggie sniffled a little uncomfortably, as a werewolf, it is also a tragedy that her nose is too sensitive: "But I can't figure it out at all now, how did the original reconnaissance team bring the news back alive?" Is this a trap? But no one noticed something wrong with the scout! ”

Tang Dou couldn't explain Wing's problem to everyone, so he had to say, "Whether it's a trap or not, we have to go down at this point." Even if it's not our goal, those who transform the living dead can't let it go! ”

Everyone nodded approvingly.

"Go on!" After a while, Tang Dou found a way to continue down, and then led the way down.

"Boss, it doesn't taste right!" After walking for more than ten minutes, when the temperature and the stench of sulfur were even thicker, Po suddenly spoke. (To be continued.) )
