Barely finding a branch of a tree and crawling towards the rock wall on the bank of the river, the vastness of this underground river is simply indescribable, and the dark water is as far as the eye can see, as if the legendary River Styx is about to take away people's souls.

Follow the glow of the fireflies in your sight and climb to the zigzag rocks on the riverbank, which are also the result of the river's erosion. Climbing up the rock platform layer by layer, it was difficult to climb far away, and Zhang Lan found that the glowing was not a firefly at all, but some bare spars outside the rock wall, and the faint light emitted by these spars was extremely dazzling in this dark underground world.

"Rhodolite turned out to be it?" After finally touching the end of a light, he found that these glowing hedras turned out to be the main material of the red crystal spear, and a closer look at these red crystals found that they were more transparent and pure than the goblins installed on the red crystal guns, and there were even unknown elements gently rippling in them, which was also the reason why these crystals could emit light.

Zhang Lan knocked down a large piece of red crystal with a stone for lighting, and in this process, Zhang Lan was also very careful to accidentally knock these stones up, and the result also showed that he was unfounded, without the elemental materials such as the basalt carapace and its reaction, these spars are obviously not so easy to activate.

With the spar lighting, Zhang Lan's road was much easier, and when he used the spar as a lamp to shine on the top of the rock platform, he found that there were no traces of the waterline about a hundred meters above it, and there were still caves that made him fall, these caves were large and small, and some of them faintly revealed the same light as the spar in his hand.

"It's okay, it's okay, this is not a Jedi" Seeing these caves, Zhang Lan's heart was relieved, he had been worried that there was no exit from this underground river, and if he wanted to leave here and drift along the river, it would become his only option, so that he would either be washed out of the ground by the river, or be washed deeper underground for no time, seeing the karst caves at this moment gave him a solution to his biggest problem, and the rest was how to climb to which holes, the rock platforms under his feet were only available below the waterline, and those caves above the high hanging waterline, With both of his legs broken, there was nothing he could do for the time being.

Finding a place that looked relatively stable to sit down and watching the underground river rise below him, it was estimated that it would not rise here in two or three hours, which made him breathe a sigh of relief. Took out some food from the meson generator and waited for the leg injury to recover while eating, looking at the holy wardrobe next to him that saved his life when he was bored, he had to sigh again The magic of this thing, the technology of this meson generator has obviously explored the essence of space and can use it, which is not known how many levels higher than the earth technology, and it is the goblin race with such a technological civilization that has been destroyed by the war of destruction to the extent of returning to the primitive society, Zhang Lan really can't tell what kind of scene this war of destruction is, Looking back, the red crystal weapons that are now regarded as artifacts by goblins are really not worth mentioning compared to the meson generator.

"Hey... Why is civilization so fragile in the face of barbarism? Imagining what happened to the goblin clan, Zhang Lan was even more worried about her future, and fell asleep after a while.

In his sleep, he turned into Anos and Lily to escape from Shura's pursuit, in the dream he knew that Anos would be killed on the hillside where he had saved them, he tried his best to change their escape route, but the body just didn't listen to the command and went towards his destiny without hesitation, and finally when he watched the one-horned Shura stick the stake into his throat, he woke up, and when he opened his eyes and looked at the darkness around him, he felt dazed, and for a while he didn't know whether he was Zhang Lan or Anos, Fortunately, there was still a red crystal light shining around him, so he gradually sobered up.

"Ah, my legs!" wiped his face with both hands and habitually got up and moved his hands and feet, at this time he realized that his leg injury was actually healed, and carefully put Hongjing on his leg to check and found that his legs were intact and there were no scars left, which made him feel good and swept away the depression caused by the nightmare.

"Ha, this body's recovery ability is too strong, so I still have a chance!" The strength of his physical fitness made him feel confident to deal with all crises. On his back, he found a cave with a faint red light, Zhang Lan jumped up towards the cave, this distance of more than 100 meters even Zhang Lan could not be achieved overnight, he was like a rock sheep on the stone wall trying to find the gaps and protruding rocks to accommodate his strength, and finally landed on the cave after wasting his strength.

The cave is more than three meters high, and the stalactites are craggy and very tortuous, and the red light that shines out of the cave is refracted from the stalactites at a bend. Zhang Lan wiped a handful of sweat from her head and walked towards the depths of the cave with the quiet sound of stalactite dripping.

I don't know how long this stalactite cave has been formed, the ground has been completely covered by stalactites, and the slippery feeling of walking on it makes Zhang Lan feel like walking on the corpse of a giant beast.

At this time, the whole karst cave suddenly opened up, the height expanded to more than 20 meters, what shocked Zhang Lan was that the cave wall was covered with red crystals, they were like clumps of inverted artemisia grass crowded the rock wall, these prismatic artemisia grass is as short as ten centimeters, and as long as two or three meters, more importantly, there are elements flowing in these red crystals, and the entire cave is embellished with bright and gorgeous like a swaying galaxy.

Walking in this magnificent cave, Zhang Lan had the feeling of wandering in the Milky Way, comfortable and dizzy, after walking out of a distance, he suddenly heard a buzzing sound, which made him can't help but be alert, because this sound sounded familiar to him, he slowed down and tiptoed out of a distance, he finally knew what this sound was.

Is this the sound of a mosquito flapping its wings, or is it one of the big prehistoric mosquitoes. In the final battle with Zhezhuo, he fell into the ravine, and all the way out of the mountains was fighting with this large mosquito and other prehistoric insects, during that time this sound of flapping wings can be described as his nightmare, sometimes he can wake up with several around him, and now hearing this sound again makes him goosebumps all over his body.

At this time, Zhang Lan was hiding behind a clump of red crystals and looked at the place where the sound came from, only to see a large prehistoric mosquito lying in a clump of red crystals and vibrating its wings, what made Zhang Lan feel dry in his throat was that the prehistoric mosquitoes he had encountered before were generally only the size of sparrows, and the largest was no more than a magpie. But now the one in front of him is the size of a rooster, three or four times bigger than the mosquitoes he encountered before, and which mosquitoes used to be at least insects, and the whole body of this one in front of him seems to be crystallized, and its vibrating wings have the same elemental flow as red crystals.

"This can't be the elemental beast in some graphic novels, right?" Zhang Lan was surprised by the strangeness of this mosquito, and at the same time worried about her future, if it was an ordinary mosquito, although it was more difficult to prevent from attacking, it was still very easy to deal with compared to the vulture dragon blood armor of the lizard man, but I don't know if this "elemental beast" in front of me can still be classified as a mosquito, and whether there are any special skills.

Zhang Lan hid behind the spar bush and observed the "mosquito" for a long time, he didn't want to go back to find another way because of a mosquito with an unknown background, after all, it was too wasteful of time, he didn't know how long he had been in this space underneath, to what extent the battle between the goblins and the lizardmen had progressed, and whether the task given to him by King Zhao could still catch up. And even if he found another way, who knew if there was such a mosquito or any other danger on that road, so he kept quietly observing in the hope of finding out the habits of this mosquito in order to deal with it.

After nearly half an hour of observation, Zhang Lan found that the big mosquito in front of him seemed to be absorbing the energy in the red crystal, different from the sharp mouthparts of those prehistoric mosquitoes that he had seen sucking blood, the mouthparts of this mosquito actually looked like stamens, they put the mouthparts like stamens on the red crystal to suck, and occasionally an element would enter his body through the transparent mouthparts, and it vibrated its wings as if it was accelerating the flow of elements in the body.

"It seems that the biological properties of this mosquito are not strong, and it should not be as alert as the insects in the mountains" I was surprised that the body of this mosquito was completely beyond the scope of biological evolution, but when he came to this world, he had seen a lot of unscientific things, but he had his own views on this non-scientific thing.

Just do it, Zhang Lan strapped the equipment on her body, adjusted her breathing and touched the cave wall to the side, just as he guessed, there was no reaction to his approach to the mosquito, and even when it passed by its side in a straight line of less than two meters, it only made the big mosquito temporarily slow down the frequency of flapping its wings, and the frequency returned again when Zhang Lan walked by with bated breath.

After stepping out of more than ten meters, and finally walked out of the mosquito's territory, Zhang Lan exhaled a big breath of turbidity. Secretly proud of his boldness, but when he walked some distance again, the familiar voice reached his ears again, and this time the sound was denser and noisier.

The smug mood came to an abrupt end, and looking in the direction of those sounds, the scene ahead was almost dizzying, only to see that in the wider cave, there were more "hedron mosquitoes" lying in the huge clusters of red crystals, and the sounds of their wings were mixed together like a passenger plane about to take off at the airport, chaotic and disorderly.

Looking at those "spar bugs" that were as dense as the stars in the night sky, Zhang Lan had the urge to vomit blood, it took so much effort just now to cross a "roadblock", but now there are thousands here, which still prevents him from living.

"I still don't believe it, I'm going to explore the depth of your mosquito hole today" Scratching her head depressedly, Zhang Lan stopped caring about the thousands of spar mosquitoes in front of her.
