"Teacher...Uncle Master, do you feel a little dizzy?"

"It seems like it really feels a little." Uncle Xue shook his head.

This dizziness came very quickly, even very quickly. Then I suddenly felt my chest tightness, my body softened, and I fell into the pond with a thud.

The water was very cold, and I was a little conscious, but I wanted to hold my breath but couldn't hold it. Uncle Xue saw me falling into the water and reached out to catch me, but he also fell into the water with a thud.

I drank several big mouthfuls of water in a row, but my legs were not strong enough and began to sink.

In the last few seconds of consciousness, I vaguely saw a huge toad underwater swimming towards me in red shorts.

......

"Wake up! Wake up! Fengzi!"

My eyelids were very heavy and my head hurt. I slowly opened my eyes and saw a few familiar faces.

Xiaoxuan held my hand and asked with a panic look on her face: "Yunfeng, how are you feeling? You're so scary. Your face was almost purple before."

I had a great headache, so I struggled to sit up and leaned on the bed.

Thinking of the previous scene, I hurriedly asked, "Where is Uncle Xue!"

Xiaoxuan looked heartbroken and grabbed my hand and said softly, "Don't panic, he hasn't woken up in the east room yet. Douyazi carried you back one by one."

I woke up in the afternoon, and Uncle Xue didn't wake up until the evening. His symptoms after waking up were the same as mine, with a headache and a loss of energy.

Douyazi stood by the coal ball fire, holding the bowl and said, "Fengzi, you two are scared to death. If I hadn't been good at water, you would have almost drowned."

I applied a hot towel on my head and leaned on the bed halfway and asked, "Yazai, what happened before? Uncle Xue and I felt dizzy, why are you okay?"

Douyazai ate a mouthful of noodles and muttered, "I don't know, I've been holding my breath all the time. Is it because of this?"

"There is no doctor in the village, so I drove my head from Yongzhou overnight. The doctor said that I would call him when you wake up, and drove my head back. I guess I should be back soon."

"What did the doctor say?"

Xiaoyuan changed the towel on my head for me, took it and said, "Do you still have a headache?"

"The doctor said you were acute carbon dioxide poisoning, but fortunately the inhalation time was short. The doctor asked you to drink this medicine when you woke up. He also said that if you still have a headache within two days, you should go to the high-pressure chamber of Yongzhou Hospital for oxygen."

Xiaoxuan asked me to take mannitol, and a few bags of powders. I don’t understand why I was poisoned by carbon dioxide or something acute. If Douyazi hadn’t carried it back, I would have lost both Master Xue and I.

Could it be...that villager had the same experience as mine before? No one noticed him after a long time and was not saved?

At night, I hurried back.

Seeing that I woke up as the doctor said, I felt relieved and asked about the incident.

After discussion, we finally came to a conclusion.

Let’s ignore who steals the Taoist image. The reason why we feel dizzy, carbon dioxide poisoning is 80% related to the black holes under the pond.

Bubble water means there is breath.

If a large amount of carbon dioxide surges up from the bottom of the water in a short period of time, it will not have time to evaporate, and we happened to be standing on the shore very close to the pond, and it is indeed possible to have acute carbon dioxide poisoning. This conclusion is true.

In this way, the villager was not scared to death, but was just like us.

Douyazai recalled that he dived to the bottom of the water at around 10 o'clock and wanted to get close to the black hole to take a look. But before he got close, he felt an airflow gushing out. At the same time, bubbles began to pop in the water. Douyazai felt something was wrong and was about to float up. At this time, Uncle Xue and I fell down again.

The big toad I saw before I was unconscious was wrong, that was Douyaozi wearing red shorts.

We encountered the first problem.

Where did the black holes under the Guizai Ridge pond lead to?

Why do a large amount of carbon dioxide flow out during periods of time underwater? Where do these carbon dioxide, which is so high that it can cause acute poisoning, come from?

I couldn't figure it out at first.

Who is good at chemistry can think about it.
