Huo Yu held a can of spray in his hand and wrote a mark with fluorescent paint next to the cave channel in the middle.
This spray is specifically used to make a mark.
Spray the mark, Huo Yu took Bai Xiaomo and Ling Ran to enter the middle channel decisively.
As the three continued to deepen, the cave became narrower.
The black lacquer cave is the only light source of the flashlight, giving people an indescribable sense of depression, and the atmosphere becomes strange.
Ling Ran, who was walking behind, felt a bit cold back, and it seemed that someone seemed to peep at him silently in the dark.
This feeling is not unfamiliar to him. I have been to the underground peace in the hospital a few times before, which is very similar to this feeling now.
He bit the tip of his tongue, forcibly let himself calm, and then prepared to say something, breaking the silent and weird atmosphere.
"I said ..."
Ling Ran just spoke, and suddenly heard a sound of wings from his body, and then a weird bird screaming:
"Gurgur! (What duck, a scared baby jumps!)"
Ling Ran was scared, and turned his head suddenly, and saw a white shadow flashed in front of him, and then hit the ground directly!
Ling Ran: D (?) ??)
Xiao Xueyu: (??)?) B
One person, one person, two bolders, and the two courage, at the same time scared the other party.
Xiao Xuezhang struggled to get up from the ground, quickly flew back to Huo Yu's shoulder, and pointed to Ling Ran with his wings to start a complaint:
"Gurgu! (Uncle that pervert, scared me!)"
Huo Yu helplessly rubbed the small head like Xiaoxueya cheese cake: "What are you flying behind?"
Xiaoxue heard the words, and some shy responded:
"Gurgu ~ (Robbery ~)" "
Although Xiao Xueyu is a girl, it is also a bird of the rectum. You can't pull the raised ben on Huo Yu's shoulders.
Huo Yu couldn't help but look back at Ling Ran, who was panicked with a panic covering his heart:
"Lao Ling, you can do it, I have never heard of who perverted a bird that scares like this."
Ling Ran had a lingering heart: "I thought it was a bat, and there were a lot of bacteria viruses on the stuff, I was most afraid of that thing."
"Gurgur! (You are a bat, how can I have me so cute!)"
Ling Ran knew that he had a lot of money, and a large living person couldn't see a little bird with a bird, so he was embarrassed to smile at Xiaoxue.
"Xiaomo, after you break it." Huo Yu said to Bai Xiaomo on the side, "The first time Lao Ling came to this environment, it was a bit nervous."
Bai Xiaomo replaced Ling Ran's position, and the three continued to walk deep into the cave.
After walking for about ten minutes, there was no another fork, and the road became a lot wider.
Although everything is smooth, Huo Yu's heart is more vigilant.
There is no other reason, that is, this cave is too long.
After walking for almost half an hour, I haven't reached the exit. The interception width of this mountain is not so big.
Just as Huo Yu was about to stop and planned, Ling Ran beside him was a stun, and he almost fell to the ground.
Huo Yu's eyes raised his hand quickly, and asked helplessly: "Lao Ling, you scared something, why are you even smaller than the mouse?"
Ling Ran leaned on Huo Yu, and said a little hard: "Webmaster, not right, I'm a little dizzy."
Huo Yu heard that his face changed a lot, and he stopped quickly.
Dizzy in the cave is not a good thing, it is likely to be a manifestation of gas poisoning.
"Stopping forward, rest, small fish to be alert."
The little wolf cub who has been walking next to Huo Yu should have a good sound. The body expands and becomes loud, becoming a prestigious big wolf state, standing in the wide position in the cave and starting to alert everyone.
Together with Bai Xiaomo, Huo Yu supported Ling Ran to the stone wall aside.
He looked down at Ling Ran again. He just felt that he was particularly lazy at this time, and people seemed to be dizzy. The eyelids kept fighting, just like drunk drinks.
"Lao Ling, wake up." Bai Xiaomo pushed Ling Ran, "You are a doctor, you can show yourself what's going on."
Huo Yu also felt crying and laughing. Ling Ran himself was a doctor himself.
"It should be drunk oxygen." Ling Ran replied weakly and weakly, "tired, weak, drowsiness, chest tightness, dizziness, symptoms."
Drunk oxygen is actually 'oxygen poisoning'. Like the plateau reaction, drunk oxygen is not a condition, it is a normal physiological reaction of the human body.
In this case, most of them appear in areas who have just adapted to the low oxygen environment of the plateau and re -entered the relatively high oxygen content.
"How is this possible?" Huo Yu frowned and analyzed. "The oxygen content in the cave should be lower than the outside. How can it be poisoned by oxygen?"
Ling Ran shook his head weakly, saying that he was unclear.
Oxygen is an indispensable substance for human beings to maintain life, but exceeding the inhalation of certain pressure and time of oxygen, but it will play a harmful role to the human body.
In this case, Ling Ran is difficult to maintain his mind, let alone think about it.
"What should I do?" Bai Xiaomo was worried, "Let's say, block your nostrils, take less oxygen, can you be better."
After that, Bai Xiaomo stretched out a finger.
As soon as this remark came out, Huo Yu looked at Bai Xiaomo like looking at a fool.
Do you want to see what you are talking about?
"Vitamin E, is there?" Ling Ran barely spit out a few words.
Huo Yu's eyes were bright, and quickly turned it in the space backpack: "There are."
Bai Xiaomo on the side wanted to pick up a sentence 'Check noise', but she saw Ling Ran who was weak and felt like this was not polite, but she couldn't bear it.
Huo Yu quickly found a bottle of vitamin E, took out two, and put it in Ling Ran's mouth.
Vitamin E, also known as phenol or giving phenol, is one of the most important antioxidants. It has a strong antioxidant effect and is beneficial to the prevention and treatment of 'drunk oxygen'.
Ling Ran ate vitamin E and continued: "This thing mainly plays a preventive role. You better also eat two capsules, but for those who have symptoms, it is still cure."
Huo Yu quickly asked: "How can I cure the root cause?"
"Most of the cases do not need to be treated, and it can be relieved by rest." Ling Ran paused, and said, "However, the treatment of high -pressure oxygen tank is better, or it takes some low concentration of oxygen."
"Yes!"
Huo Yu's eyes were bright, and he began to find it in the space backpack.
Bai Xiaomo and Ling Ran looked at each other at each other, and a few vomiting pressed in their hearts, not to vomit.
"Are your kids special?"
Huo Yuzheng said: "I'm not a Treasure Taoist, I am the strongest robot in the universe -Doraemon."
