He Wenwen's body has improved a lot, and she can already walk slowly with Du Lin's support, and the dizziness caused by the concussion has also been reduced a lot.

In the process of being helped by Du Lin to walk, He Wenwen looked at Du Lin's eyes with some admiration, some shyness, and some "little stars" in her eyes.

Of course, Durin noticed this, and said in his heart, this is the normal reaction of the blood effect!

But it will also be a trouble in the future, in the past thousand years, there have been several women of school age who have drunk Durin's "immortal blood", but the final outcome is not very good - the most infatuated and bitter, and it will be mistaken for life at first sight.

Du Lin didn't want He Wenwen to be like those girls, after all, she was his friend and half a relative, so he needed to find a way to solve this problem.

But this is all for later, the two most important things at the moment, one is to get out of this sinkhole, and the other is the stinky ghost.

It seems that it will be enough to choke for a while if you want to go out, this ghost place, there may not be a living person passing by for a few years.

It's okay for stinky beauties now, the first is that there is no umbrella, and the second is invisible.

Durin patted his head, angry, annoying, and angry......

Since nothing can be solved, then put it aside, understand the surrounding environment first, and live the life in front of you.

Duhrin explored along the bottom edge of the sinkhole, the bottom of the entire sinkhole was about 300 meters in diameter, less than a kilometer in circumference, and it took ten minutes to complete a circle, there was an underground river channel at the bottom of the pit, and the sound of the water was not very loud, but the reason why the sound of the water was not loud was not that the water was not fast, but because the water surface was far away from the mouth of the cave. In other words, the water has washed away the rock formation below the bottom of the pit very badly, and the bottom of this pit is actually "hollow", and the height of this hollow is still very high, and it is very likely that it will collapse again and become a deeper sinkhole, but I don't know when this collapse will occur.

There is a two-meter-square cave where the river and the pit wall meet, the cave is dark, I don't know how deep it is, at the entrance of the cave, Durin saw the corpse of a bat on the ground, Durin curiously pulled up the bat's wings with his hand and looked at it, and the same as the bat in the impression, this bat looks extremely ugly, with a rat head and a dog face and a pig nose, and 4 big fangs in its mouth, it looks like it should be a vampire bat that lives on animal blood, Durin smiled, or a peer.

There are blood stains on the head of bats, which may be caused by hitting their heads while flying, but elementary school students know that bats rely on ultrasonic echolocation to fly, and it is basically impossible to hit their heads.

Durin examined it carefully, and it turned out that the bat's ears were sick, and they were full of pus and blood, so naturally he could not hear the echo of the ultrasound.

Just as Durin was about to throw away the bat's corpse, he suddenly noticed that there were rows of small holes in the bat's wings.

This is a small hole pierced in the bat's wings with a needle-like object, looking carefully at the sunlight on the top of the pit, only to see that these small holes form a sentence of Chinese characters, the left wing is written: "Shanhe Industrial He Wenjing", and the right wing is written: "North latitude XX.XXXX, east longitude XXX.XXXX, save me!"

Du Lin's eyes lit up, the second sister is really alive! and she is still trying to survive!

He carried the carcass of the bat back to the tent, "Wenwen! Come and see, the second sister is still alive." ”

"Have you found the second sister?" He Wenwen hurriedly climbed out of the tent when she heard the sound, and after walking a few steps, she felt a little dizzy, swaying and almost falling, Du Lin hurriedly threw the body of the bat aside, and helped He Wenwen, who was about to fall.

He Wenwen leaned on Du Lin's arms, staring at Du Lin from the bottom up with a pair of big eyes, with pretty eyebrows.

The pink face was shy, and for a while, an ambiguous atmosphere filled the surroundings of the two.

Durin was also a little intoxicated for a while, and his heart, which had not throbbed for many years, seemed to loosen a little.

It was Du Lin who came to his senses first, he helped He Wenwen to stand firmly, took two deep breaths, stabilized his mind, and lifted the bat corpse from the ground.

"Look here," Du Lin pointed to He Wenwen with the small hole in his wings, "This must have been stabbed by the second sister, right?"

"That's right! It's the second sister!" He Wenwen also quickly returned to normal, she carefully looked at the stabbed words, and touched them with her hand, and said excitedly, "Our second sister is a Jin Yong fan, she doesn't know how many times she has read Jin Yong's novels, I always asked her to borrow novels to read when I was a child, the words on the bat's wings are obviously imitating the plot of "The Legend of the Condor Heroes", the little dragon girl is trapped at the bottom of the desperate valley, and the words are tattooed on the wings of the jade bee. ”

"Great, I finally know the news of the second sister!"

"What's the use of knowing? At least Xiaolongnu said that she understood that she was at the bottom of the 'desperate valley', but the second sister only wrote a latitude and longitude, but our GPS locator was broken, besides, we are all trapped in this sinkhole now, even if we know where the second sister is, we can't save her!"

"Not necessarily," Durin shook the bat corpse he was carrying, "don't forget, how did it get in?"

"Bats? People can fly! We can't fly. ”

"Last night, I saw a group of bats flying out of this sinkhole, and the corpse of this bat, I saw it at an underground estuary on the edge of the sinkhole. ”

"What does the fifth brother mean is that the nest of these bats is somewhere else, and they come to this sinkhole every day through the underground river, and then start from the sinkhole to go outside to find food, and then go back through the underground river, and this sinkhole is the entrance and exit for them to forage?"

"It must be like this, and the second sister will definitely be able to touch these bats, so she stabbed a message for help on the wings of these bats, hoping that others would see it. ”

"Then what are you waiting for, let's go find the second sister!"

"What are you anxious about? Do you know if these bats are coming from the upper reaches of the underground river or from the lower reaches of the river? You just go to find them? Besides, you don't know the situation of the underground river, how deep the water is, how wide the river is, the temperature of the water, the speed of the current, whether there are any dangerous fish in the water, you don't know anything, you have to go into the water?"

He Wenwen stuck out her tongue and smiled.

"Besides, there's a stinky ......" Durin wanted to say that there was still a stinky ghost problem that hadn't been solved, but he was afraid that if he said that the stinky ghost had been on her, it would scare her, so after thinking about it, he didn't say anything.

"What stinks?" He Wenwen asked.

"It's nothing, I said you stink, it's time to take a shower. Durin casually lied.

"Huh?" He Wenwen hurriedly sniffed and sniffed on herself, "Do I stink?" No, I want to take a bath, where is the underground river, I want to take a bath!"
