The guide, Master Wang, pointed to the fork in the road on the left and then to the fork in the road on the right, waiting for Nan Hanfei's decision.

Nan Hanfei was a little hesitant and wanted to choose one at random, when suddenly there was a sound of Suo Suo from the right fork in the hole.

It sounded like something scraping against the ground, or like the movement of some animal crawling.

Lu Li suddenly felt creepy, "There won't be any beasts in this cave, right?" ”

The guide, Master Wang, was the first to retort, "Since we entered the Misty Valley, we have not had any living creatures all the way, where are the beasts?" ”

Lu Li: "It's not a beast, what is it?" Listening to the sound is a living creature. ”

"It's not a beast, it's probably a man." Gu Yanan said.

"Hope is the second group of missing people from the Marina Tourism Development Company." Nan Hanfei also said softly.

Everyone felt closer and closer to the truth, and they all walked into the cave at the fork in the right side.

The cave inside the fork is more open, the ground is flat, and there are traces of manual excavation and polishing.

After walking more than a dozen steps in the cave at the fork in the road, the guide, Master Wang, suddenly said, "Why does this cave smell of mustard?" ”

Gu Yanan's heart tightened, and he hurriedly came to Master Wang's side to check the protective equipment on his body.

As expected, the protective suit on Master Wang's body cracked, which was cut by sharp mountain rocks when he passed through the woods just now.

"Master Wang, you quickly leave the cave, go to Wang Xiaoxiao and them outside the cave entrance, stay with them, and say that you may have inhaled mustard gas, and let Wang Xiaoxiao give you emergency treatment."

As soon as Master Wang heard that he had inhaled poisonous gas, his heart was pounding with fright, and he immediately left the cave according to Gu Yanan's instructions.

Gu Yanan asked the remaining people again, "Do you smell anything strange?" For example, mustard or stinky garlic. ”

Lu Li and Zhou Jie replied one after another, "Our protective clothing is complete, no problem." ”

Nan Hanfei also followed closely and said, "I paid attention to protecting this dress on the road, and I didn't have any problems." ”

The four of them continued to walk forward, and walked a distance of about a few tens of meters, and in the light of the flashlight facing forward, everyone saw a black shadow crawling on the ground.

Dark shadows wriggled on the ground, moaning in pain from time to time.

"It looks like a person!" Lu Li exclaimed.

The four of them stepped forward and found that the black shadow on the ground was indeed a person.

The man was dressed in clothes with the words of the Coastal Tourism Development Company, his hands were black, his face was covered with blisters, and he tried to climb to the mouth of the cave with his hands and feet on the ground.

Gu Yanan hurriedly helped the man to sit up.

The size and appearance of this person can be identified as a middle-aged man.

Seeing the people around him, the middle-aged man made a staccato voice in his throat, "Help...... Help me......"

The middle-aged man was seriously injured, and Gu Yanan immediately ordered the people around him, "Take him out first." ”

Four people helped the injured middle-aged man out of the hole.

Outside the entrance of the cave, Wang Xiaoxiao and disease control personnel from two counties are giving the guide Master Wang emergency treatment after contact with mustard gas, first washing the bare skin with alkaline soapy water, and then rinsing with plenty of water.

Wang Xiaoxiao saw Gu Yanan and they brought out another seriously injured person, and hurriedly took the emergency medical kit and wanted to come over to help.

But after seeing the middle-aged man's injuries clearly, he realized that the emergency medical kit in his hand had no effect at all.

Gu Yanan smiled at Wang Xiaoxiao and said, "Call the city's emergency medical team and say that there are at least two people suspected of mustard gas poisoning here." ”

Wang Xiaoxiao: "I have called just now to inform you, and the medical team said that they will send an emergency helicopter." ”

The injured middle-aged man took Gu Yanan's hand and said painfully and laboriously, "Inside...... And ......"

Gu Yanan listened anxiously, followed the meaning of what he said just now, and asked, "Is there still your companion in the cave?" ”

The middle-aged man nodded, "Two!" ”

Gu Yanan was about to go into the cave to save people again, but as soon as he stood up, he was pulled by a middle-aged man and grabbed the corner of the protective suit.

"Poisonous, dangerous!"

Gu Yanan leaned down again and asked, "What danger?" What do you see in the cave? ”

The middle-aged man's voice was hoarse, "metal can...... Poisonous...... A lot...... Can't touch it! ”

Gu Yanan knew that the middle-aged man was reminding her.

Gu Yanan connected the middle-aged man's words and repeated: "You mean that you have found a lot of metal canisters in the cave, and these metal canisters are poisonous, and you are just injured by the contents of the metal cans. ”

The middle-aged man nodded.

Nan Hanfei asked, "Where are those metal cans in the cave?" ”

"Right...... Fork in the road...... More than 100 meters ahead...... Hall...... There are four ......"

Although the injured middle-aged man spoke intermittently, the words he said were all key words.

Nan Hanfei connected all the key words together, "You mean, enter from the fork on the right just now, and walk more than 100 meters further, there will be a large cave hall with four metal canisters inside, and they are the source of the poison gas?" ”

The middle-aged man nodded again, closed his eyes tiredly, and did not intend to speak again.

He had already provided enough information, and Nan Hanfei and Gu Yanan decided to enter the cave again and rescue the remaining two people.

Nan Hanfei, Gu Yanan, Lu Li, and Zhou Jie wore protective clothing, entered the cave again, and followed the route just now to find the hall in the cave that the middle-aged man said.

The hall is a square cave that has been dug out by hand, like a storeroom and a laboratory, with several metal cans piled up inside.

The metal jar was more than half a man tall and was rusted on it.

Gu Yanan approached the metal canister and wanted to find some clues from the surface of the metal can.

There is a mark in the lower middle of the jar with a vague sun flag on it.

Gu Yanan carefully observed the metal cans.

Most of the metal cans were rusty but intact, and one of them had a crack near the top end, and the poison leaked from the cracked canister.

Gu Yanan's first reaction: This is a biological and chemical weapon left by the Japanese army during World War II, and because of the long time, it has begun to leak poisonous gas.

The source of the poison has been found, but what about the two missing people?

The four of them stood in the cave hall and heard the sound of running water.

Lu Li walked towards the sound of water, and after walking more than ten meters, he found an underground dark river.

The dark river is turbulent and is the groundwater in the Qingcheng Mountains.

After four metal cans, this underground river next to the rock wall of the cave, the river water hits the rock walls on both sides and makes a tinkling sound.

Lu Li used a flashlight to shine around the underground riverbank, and found two figures crawling on the bank, one of which seemed to be still squirming.

"There's someone over here!" Lu Li shouted.

The four of them all gathered on the bank of the underground river and found that the two people lying on the bank were wearing clothes with the words "Coastal Tourism Development Company", and their symptoms were the same as the person they had just rescued, their faces were covered with blisters, and their hands were black.

Gu Yanan wiped the pulse of the two of them, and one of them still had a faint breath, which made the other body stiff.

"This one is still alive." Gu Yanan pointed to one of them, "Be careful to carry him out, and take the remaining one with you." ”
