He Wenwen's health has improved a lot and she can now walk slowly with Du Lin's help. The dizziness caused by the concussion has also been relieved a lot.

While being supported by Du Lin to walk, He Wenwen looked at Du Lin with a look of admiration, a little shyness, and "little stars" in her eyes.

Of course Du Lin noticed this and said to himself, this is a normal reaction to the blood relationship effect!

But there will be trouble in the future. Over the past thousand years, several women of the right age have drank Dulin's "immortal blood", but the final outcome was not very good - the most painful is infatuation, a misunderstanding for life.

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 are getting out of this sinkhole and the other being the stinky beauty.

It seems that it would be too much to go out for a while. It is unlikely that a living person will pass by this ghost place for several years.

It's not easy for me to be a beautiful girl now. Firstly, I don't have an umbrella, and secondly I can't see her.

Du Lin patted his forehead, feeling so angry, annoyed, and angry...

Since nothing can be solved, let's put it aside first, understand the surrounding environment, and live the life in front of us.

Du Lin explored along the edge of the bottom of the tiankeng. The entire bottom of the tiankeng was about 300 meters in diameter and less than one kilometer in circumference. It took ten minutes to complete a circle. There was an underground river at the bottom of the pit, and the sound of water could be heard.

It's not very loud, but the reason why the water sound is not loud is not that the water flow is not fast, but because the water surface is far away from the entrance of the cave. In other words, the water flow has severely washed away the rock formations below the bottom of the pit. The bottom of the pit is actually "

"Hollow", and the height of this hollow is still very high. It is very likely that it will collapse again and become a deeper sinkhole. But we don't know when this collapse will occur.

Where the river intersected with the pit wall, there was a two-meter-square cave that went straight up and down. The cave was pitch black and it was unknown how deep it was. At the entrance of the cave, Du Lin saw a bat corpse on the ground. Du Lin curiously used

I picked up the wings of the bat and looked at it. It was the same as the bat in my impression. This bat looked very ugly. It had a rat head, a dog face, a pig nose, and four stars in its mouth.

With its big fangs, it looked like it was a vampire bat that lived on animal blood. Dulin smiled, and he was still a fellow traveler.

There are blood stains on the bat's head, which may be caused by hitting its head while flying. However, as all primary school students know, bats rely on ultrasonic echolocation to fly, so it is basically impossible to hit their heads.

Du Lin checked it carefully again and found that the bat's ears were diseased and filled with pus and blood. Naturally, the ultrasound echo could not be heard.

Just when Du Lin wanted to throw away the bat carcass, he suddenly discovered that there were several rows of small holes in the bat's wings.

These are small holes punched into the wings of bats with a needle-like object. If you look carefully at the sunlight on the top of the pit, you can see that these small holes form a Chinese character. What is written on the left wing is: "Shanhe Industrial He Wenjing"

", what is written on the right wing is: "North latitude XX.XXXX, east longitude XXX.XXXX, save me!"

Du Lin's eyes lit up. The second sister was indeed alive! And she was still trying to survive!

He carried the bat's body back to the tent and said, "Wenwen! Come and see, the second sister is still alive."

"Have you found the second sister?" He Wenwen quickly climbed out of the tent after hearing the sound. After taking a few steps, she felt a little dizzy, staggered and almost fell. Du Lin quickly threw the bat's body aside and

He supported He Wenwen who was about to fall.

He Wenwen leaned on Du Lin's arms, staring at Du Lin from bottom to top with her big eyes, her eyebrows were pretty,

Their pink faces were shy, and for a moment, an ambiguous atmosphere filled the surroundings of the two of them.

Du Lin was also a little intoxicated for a moment, and his heart, which had not throbbed for many years, seemed to be a little loose.

Du Lin woke up first. He helped He Wenwen stand upright, took two deep breaths, calmed down, and lifted the bat body from the ground.

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

"That's right! It's the second sister!" He Wenwen quickly returned to normal. She looked at the tattooed words carefully, touched them with her hands, and said excitedly, "Our second sister is a fan of Jin Yong, Jin Yong's novels

She has read it countless times. When I was a child, I would always ask her to borrow novels to read. The words on the wings of this bat are clearly

Is it imitating the plot in "The Legend of the Condor Heroes" where the little dragon girl is trapped in the bottom of the heartless valley and tattoos words on the wings of a jade bee to send a message."

"Great, I finally know the news about my second sister!"

"What's the use of knowing? At least Xiao Longnu made it clear that she was at the 'Bottom of Heartlessness', but the second sister only wrote one latitude and longitude, and our GPS locator was broken. Besides, we are all trapped in it now.

In this sinkhole, even if I know where my second sister is, I can't save her!"

"That's not necessarily true," Du Lin shook the bat corpse in his hand, "Don't forget, how did it get in?"

"Bat? He can fly! We can't fly."

"Last night, I saw a group of bats flying out of this sinkhole, and I saw the body of this bat at the mouth of an underground river on the edge of the sinkhole."

"What Fifth Brother means is that the nests of these bats are in other places. They come to this tiankeng through underground rivers every day, and then go out from the tiankeng to find food, and then go back through the underground rivers. This tiankeng

Is the pit an entrance or exit for them to forage?”

"That must be the case, and the second sister must have access to these bats, so she tattooed 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 quickly!"

"Why are you so anxious? Do you know whether these bats come from the upstream or downstream of the underground river? Just go and find it? Besides, you don't know the condition of the underground river. How deep is the water? How wide is the river? What is the water temperature?

The speed of the water flow, whether there are any dangerous fish in the water, you don’t know anything about it, so why don’t you go into the water?”

He Wenwen stuck out her tongue and smiled.

"Besides, there is another stinker..." Du Lin wanted to say that there was another stinky ghost who had not yet solved the problem, but he was afraid that if he said that the stinky ghost had had sex with her, it would scare her, so he thought about it.

Still don’t say it.

"What does it smell like?" He Wenwen asked.

"It's nothing, I said you smell bad and it's time to take a shower." Du Lin lied casually.
