When Qi Lingshan had already killed the traitor, the next task was very simple, that is, to find a way to rescue the trapped Xu Xing. To do this step first, the first thing to do is to find out the situation in the cave, if you can't even figure out the situation, it is nonsense to want to save people.

Shen Feng thought for a while and said, "Tyuming's words, there is no need to go back, since they are all a group of white-eyed wolves, there is no need to save them, anyway, we don't need Tyuming's oil." ”

Shen Feng also knew that the most important thing now was to find a way to rescue Xu Xing, and then immediately take people to the cave, first of all, to find a way to find out the situation in the cave, as for the cave dug by the marmot, it has been blocked now, and it is obviously impossible to go to the marmot's cave.

"City Lord, the hot springs are still easy to pass, and you can pass by throwing stones, but the salamanders in there are not easy to deal with, there are too many of these things, and they are very aggressive, and it is not so simple to cross the hot springs." Lu Xian hurriedly said.

If it was just a hot spring, Lu Xian was not very worried, because the hot spring was not very deep, the deepest place was more than one meter, and the edge of the stone wall on both sides of the water was very shallow, as long as you stepped on the stone, you could go directly to it.

However, it is impossible for anyone to believe that something that can live in a water temperature of more than 100 degrees Celsius is not harmful, and animals living in a treacherous environment must not be easy to match. And, most importantly, Lu Xian didn't know if these salamanders were poisonous or not.

"Anyway, let's try to cross the hot springs at this time, and then continue to explore the terrain and the like when it's over." Shen Feng also felt that the salamander was more tricky, because he had never seen such a strange thing, and he didn't know how strong the other party's strength was.

Shen Feng and the others then carried the stones to the cave, and there were many huge footprints in the cave, needless to say, these footprints were left by the tree people.

"Speaking of which, it seems that the Tree Man can safely survive the hot springs here, and the salamanders won't attack the Tree Man? Also, why didn't the Treants catch the salamanders that live in this place? Qi Lingshan suddenly became curious, at this time he thought of a problem, the food source of mutated plants is dependent on the tree man to tie the animal to the inside of the cave to digest, as a result, there are many salamanders in the hot spring, but the tree man does not do it, which makes people puzzled.

When Qi Lingshan said this, Lu Xian also felt strange, but Shen Feng explained at this time: "That's because mutant plants are also intelligent, and now mutant plants have a nervous system and learn to think, so Xu Xing will be betrayed, and the most important thing is that the salamanders living in these hot springs can also be used as bodyguards to block the enemies of the cave they enter, why not?" ”

No one else has ever been in contact with mutant plants, but Shen Feng has seen a lot of mutant plants here, and he also knows very well that the mutant plants at the moment have the ability to think, so for salamanders, staying as a watchdog is a good choice.

Qi Lingshan heard Shen Feng's explanation, and also understood why the mutant plant kept the salamander in the hole unmoving, and it was actually regarded as a defensive force, and the level of intelligence was not simple at all.

After going hundreds of meters underground, there was no light here, there was no lighting facility here, Shen Feng had to turn on the flashlight and light it into the cave, it was hard to imagine that there was such a hidden place in the depths of the forest, and besides, there was such a warm place under the icy Siberian sky.

Generally speaking, hot springs always appear with volcanoes, because the heat released by the magma is transferred to the hot springs, so it will cause the hot springs to have a high temperature, but in Siberia, it stands to reason that there are no hot springs, Shen Feng couldn't figure it out at that time, since there is no volcano, where did the hot springs come from?

"City Lord, look here, we don't seem to need to report stones, there is already a road on the stone wall." At this time, Lu Xian noticed that there was something on the stone wall on one side, so he immediately began to report, and Shen Feng also shone the flashlight to the side.

Shen Feng suddenly found that on the stone wall on one side, there was a neat row of pitons, these pitons were already rusty under the fumigation of water vapor, and most of these pitons were left by the people who entered the cave a month ago.

In the steam-rich caverns, the speed of steel rust is so fast that a casual wipe of pitons will reveal a thick layer of rust, and after a while, at most half a year, these pitons will be unable to walk.

However, for now, the pitons can still support the weight of an adult, but they need to maintain balance on the pitons, otherwise they will be cooked once they fall into the hot springs.

"Alas, I was busy working in vain, and I came down from the outside with a big stone of more than eighty catties, but I couldn't use it." Shen Feng was also very helpless, blaming it for being disrupted by the salamander yesterday in a hurry, so that the pitons on the wall were not found, but fortunately, only three stones were moved, which was not a big deal.

"Throw the stone aside, follow me, and just go over while the salamander is not alarmed now." Shen Feng hurriedly said.

After Shen Feng finished speaking, he took the lead and stepped on the pitons, holding the wall with one hand, and holding a flashlight in the other hand to illuminate, and then walked towards the depths of the cave, and the other two also hurriedly followed Shen Feng's footsteps, the cave was very quiet, the three of them stepped on the rusted pitons and walked, and the rust kept falling into the hot springs, fortunately, the degree of rust of the pitons was not particularly serious, otherwise, the three of them could only use the soil method, using stones to build a road on the ground, which could not be done in a day or two.

When the three of them were walking quietly, the water surface of the hot spring suddenly changed, and red-skinned salamanders came out of the small holes on both sides, these salamanders looked like they were just the size of rabbits, and they were not a big deal in terms of size, even an eight-year-old child could solve them, but one thing to know was that these salamanders were drilled out of the hot springs of more than 100 degrees, and the animals living in extreme environments should not be underestimated.

After thinking of this, Shen Feng immediately cast "Follow the Wind", stepping on the pitons, and a second later, Shen Feng had already appeared on the shore in front of him, where the terrain was undulating, and the hot spring could not spread.

Lu Xian, who was in the middle, ran away when he saw Shen Feng in front of him in a flash, and immediately couldn't help but ask: "City Lord, you are too unrighteous, you walked over, what should we do?" ”

At this time, dozens of salamanders had appeared in the hot spring, all of them surrounded the remaining two people on the pitons, and the pitons were only forty or fifty centimeters away from the water surface of the hot springs.

Shen Feng stood on the shore and hurriedly said, "Don't complain, just go quickly, I'm not here to cover you?" ”

Shen Feng can stand on the surface of the water, so even if he falls into the water, he will not sink, but Shen Feng didn't want to get close to these axolotls that he had never seen before, so he went ashore directly, and seeing that Lu Xian and Qi Lingyi on the pitons were threatened by the salamanders, he hurriedly launched a wind blade to stop the salamanders from approaching.

"Boom ......" one by one wind blades were launched, and instantly hit the axolotls that were approaching in the hot spring, and the salamanders were also killed, but when the salamander died, there would be red blood flowing out of the body, and the original pale green hot spring turned bright red immediately after being polluted by the salamander's blood.

However, in the dim light in the cave, Shen Feng couldn't see the position of the salamander clearly, especially after the salamander was killed more than twenty times, the hot spring was dyed red, and the salamander's body was already red, and now Shen Feng couldn't determine where the salamander was.

Lu Xian and Qi Lingshan were already moving forward as soon as possible, if they were on the ground, the distance of fifty meters was nothing at all, and it would pass quickly, just a few seconds, but at this time, the two of them were standing on top of the pitons, it was not easy to balance themselves, and they also needed to worry about falling at any time, and it was not easy to reach the shore quickly.

Taking advantage of the opportunity when Shen Feng couldn't see the salamander clearly, the red-skinned salamander in the hot spring was rapidly approaching at this time, and actually surrounded Lu Xian and Qi Lingshan on top of the rock piac, which was still more than ten meters away from the shore, not far away, not short.

"What, I don't want to provoke you, but you are aggressive, you are really too deceitful, so provoke me, do you really think I have no temper at all?" After Qi Lingshan found that he was surrounded, he really couldn't stand it, he retreated again and again, and you primitive creatures still kicked their noses and faces, since this is the case, leave me alone.

Qi Lingshan immediately came to exert his ability, a stream of liquid nitrogen in the air flowed down instantly, the current low temperature that can be achieved in the industry is basically achieved by using liquid nitrogen, and the temperature of dozens of degrees below zero can also be done, now, the liquid nitrogen flows down and falls on the surface of the hot spring, at that time there was a "snort" sound, a large white fog in the air appeared, cold and hot excited, and the temperature in the water also began to change sharply, sometimes it was a high temperature of more than 100 degrees, and sometimes it would drop to more than ten degrees.

As a result, the salamanders in the water can't stand it, these salamanders can live in hot springs with high temperatures, but they have no tolerance for low temperatures, and the spring water near the area of Qi Lingshan is cold and hot, so drastic temperature changes make salamanders feel severe pain all over their bodies.

Then, the salamander, which couldn't stand it, immediately began to flee the area around Qi Lingyi, giving up all the water.

Qi Lingshan didn't expect that his ability effect would be so good, and he could directly force the salamanders in the hot spring to retreat, if he had known that he could have such a good effect, why should he be so anxious.

"One thing descends one thing, and I am the nemesis of your primitive animals." Qi Lingshan said directly.

The salamander is a very primitive animal, under normal circumstances, it is not seen in the wild, only in the depths of the cave, in the inaccessible place can be seen in the wild, millions of years ago it looks like this, and it still looks like this after millions of years, so for many people, the ugly thing of the salamander is the primitive species.

Lu Xian didn't dare to be careless, even if the salamanders didn't attack for the time being, it was best to go to the shore as soon as possible to save a little more moths.

"Don't talk too much nonsense, let's go ashore now, and be careful of falling into the water and cooking." Lu Xian said as he quickly approached the shore.

On the other hand, Qi Lingshan's side walked unhurriedly, and he didn't seem to be worried about the underwater salamander at all, anyway, he only needed to continuously release liquid nitrogen to reduce the temperature in the hot spring, in this case, the salamander didn't dare to approach at all, and Qi Lingshan didn't worry about being attacked.

Lu Xian quickly went ashore, and after coming to the shore, he saw Qi Lingshan walking unhurriedly, at this time, suddenly a salamander jumped up from the water and pounced towards Qi Lingshan, Lu Xian hurriedly reminded loudly: "Be careful behind you." ”

Qi Lingshan had also seen the salamander coming out of the water, and hurriedly pulled out the long sword at his waist and slashed it down with a sword, dividing the salamander into two at that time, and the salamander's blood sprayed out and fell on Qi Lingshan's face.

"Ah, it's hot, it's boiling water." Blood fell on Qi Lingshan's face, and as soon as it came into contact with the skin, he felt a sharp pain in an instant.

Afterwards, Lu Xian rushed directly to the shore, found a handkerchief from his backpack and began to wipe it, wiping the salamander blood off his face.
