The next time he saw Wang Buran, he had been quietly teleported to the entrance of the grotto, looking out, the fight between humans and firebirds, it was chaotic, but everyone was trying their best to cover Sen Ming who was running towards him, don't look at it was a short distance, but it was extremely difficult to shuttle in the sea of fire.

Wang Buyan couldn't manage so much, and the most important task at the moment was to get the energy body and leave quickly, so he just judged the surrounding environment and drilled into the hole.

The cave is both damp and cold, Wang Buyan found that there are many holes here, if there is no help from the Xingnian system, it will take a lot of time just to distinguish these identical holes, plus the strange rocks here, the yin wind is constant, as if in the underworld, I am afraid that it will be too late, let alone find the way calmly.

Moreover, the trend of this cave is downward, as long as you are not careful, stepping on any slippery moss, you can also fall for a long time.

However, all this is Wang Buyan's unique advantage, because with the help of Mosfit, he can avoid many detours, and when he just arrived at the entrance of the cave, Mosfit had a violent reaction, saying that there was a strong energy group reaction in one of the directions.

After Wang Buran learned the news, he drilled into the depths of the cave, now the temperature is getting lower and lower, the bright moonlight can no longer cover this place at all, and the cool breeze blowing in his face has drilled a hole in the sleeve of his military coat, which can't help but cause him to shiver from time to time.

"Tick, tick, tick......"

As the cave progressed, the environment inside became more humid, and you could clearly hear the water dripping from the rock walls, and every sound made one feel a little scary.

Wang Buyan took into account that there was not much energy left in the chip, so he only occasionally turned on the Xingnian system to ensure his safety and the path he chose was correct, and other times, he relied more on the flashlight bought cheaply in the department store to find the way.

Besides, the 20-meter limitation of the Xingnian system is there, unlike a flashlight, as long as there is no obstacle to block it, it can be illuminated anywhere.

Therefore, although he can temporarily ensure the safety of his surroundings and the accuracy of the road, every time he leaves the Xingnian system, a person in this dark and damp cave, relying on a cheap flashlight bought for twenty yuan in a department store, cannot help but feel frightened.

"Twitter, twink......" There was a strange sound in the dripping sound, and a creature seemed to pass by Wang Buyan's feet, and even a few hairs brushed his bare ankles.

"Wow! something!" Wang Buyan quickly shrank his feet, and then roared in fright.

Shine the flashlight at his feet, only to see a dirty big hairball, with a long tail behind him, lying motionless at his feet, it was a very strange-looking mouse, probably because of the long-term existence in this place without light, the mouse's eyes have been completely replaced by white, but the lack of vision does not affect its normal action at all.

"It turned out to be a mouse, although the eyes have deteriorated, but the other senses seem to have become more sensitive, it is because it feels the temperature, it came here...... Wang Buran said after suppressing the shock.

"I didn't expect that there were other creatures in this cave, but I couldn't just open the Star Mind System, in case the energy ran out by then, there would really be no tricks. ”

However, Wang Buran's shout was heard by Sen Ming, who was vaguely trapped in the selection hole: "What movement...... Do you want to check it out...... In case, in case, forget it, for the sake of the little sister, I have to fight. ”

Continuing towards the cave, there were shaded mosses that made it even more difficult for the uneven rocks to gain a foothold.

No, as soon as he finished speaking, Wang Buyan accidentally stepped on the moss on the soles of his feet, followed the sinking trend of the cave, and rolled all the way down until he hit a big rock, and finally stopped.

"Hey, it hurts, it hurts, it hurts...... it hurts" Fortunately, the thick cotton clothes worn by Wang Buyan cushioned a lot of impacts for him, otherwise the injuries he suffered might not have been more than scratching the skin.

After rolling all the way for so long, and now that he has arrived in a very unfamiliar place, Wang Buran hurriedly turned on the Xingnian system, carefully checked the situation within twenty meters of the surroundings, and only after making sure that there was no danger, did he turn it off again.

But after turning on the flashlight in his hand, Wang Buran was shocked by this scene to the depths of his heart.

This grotto, is a typical example of karst landform learned in geography class, very rare calcium carbonate precipitate accumulates on the ground, hanging upside down on the roof of the cave, some of these stone stalactites are like bamboo shoots, some are like coral, clusters of different shapes, one by one is shiny and clear, decorated in this empty grotto, making people feel as if they are in an underground crystal palace.

Turning the flashlight down, through a thin layer of mist, you can see that the bottom of the grotto is a natural lake, the area of the lake is not large, but it is very deep, and it seems that there are few impurities in the lake, and the direct light from the flashlight still penetrates to the bottom of the lake without a trace of obstacles.

In the middle of the natural lake, there is a wonder that makes people sigh, that is, a layer of stone towers, rising from the lake, like Optimus Prime, straight to the top of the cave more than ten meters high, its development momentum, as if to connect the cave from the bottom to the top will stop.

Wang Buran deeply sighed at the masterpiece of nature: "The book says that stalactites will only grow about one millimeter every year, these tall stalactites, I don't know how many years of precipitation to evolve, nature's means of creation, it is really breathtaking." ”

"I just don't know if I'm the first human to visit here in tens of thousands of years......"

Wang Buran realized that he had reached the end of the cave by mistake.

"Master, master, a total of fourteen energy sources have been detected in the vicinity. Mosfit interrupted Wang Buran's emotion.

"What! Fourteen, wow, it's been sent, where is it?"

"The top of the stone tower in the lake. Mosfeldt replied.

This answer was like a basin of cold water, and Wang Buran's dream of making a fortune that had just been ignited was immediately extinguished.

"Tsk, it's a little troublesome......" Seeing the food delivered to his mouth, but he couldn't eat it immediately, Wang Buran felt a little anxious.

"But fortunately, those energy sources are concentrated on the top of the stone tower, which means that now the only problem left is how to reach the top of the stone tower...... Fortunately, there was a need to climb beforehand. ”

After finishing speaking, Wang Buyan immediately took out a bundle of thick rope from the chip space, plus a sharp and sharp pickaxe, with these tools, under the condition that the tenacity of the stone tower allows, it should not be a problem to climb to the top of the stone tower of more than ten meters.

Now he only had to probe if there was any danger in the inexplicable lake that had to be crossed, and he could proceed to the final step of his treasure hunt as planned.

Wang Buyan turned on the Xingnian system and probed within 20 meters of the lake, but found no trace of any living creatures.

But Wang Buran still didn't dare to go into the water, he always had a difficult hurdle in his heart about this unfamiliar water, besides, what he detected was only within twenty meters in front of him, and the area of this lake was so large, it would be difficult to say if there was anything strange in other places.

"Why don't you walk around the lake and have a look......" Wang Buran was still a little uneasy in his heart.

But at this moment, he suddenly heard some faint footsteps coming from the hole behind him, and then he immediately changed his mind: "No, you must get the energy source before them, and then leave, otherwise the trouble will be even greater." ”

When Wang Buran thought of this, he immediately took off his cotton clothes, no longer saving energy, and turned on the Xingnian system to the extreme, so that he dared to go into the water hard, and as soon as he entered the water, the feeling brought to him by the lake made his heart furious.
