The train roared, and the four of them sat together and chattered excitedly, like girls.

Of course, because there are too many things that cannot be discussed in front of ordinary people, the four of them can only talk about other topics. Inadvertently, they talked about the current various crises. The energy and resource crises are imminent; the population crisis cannot be ignored. Due to the implementation of family planning for many years, the current plan has a population of 1.2 billion, a decrease of 300 million from its former peak! China is now developing healthily. However, a country like India has a population of more than 1.2 billion, which is said to be close to 1.3 billion; it has become the world's largest population country. Africa is a concentrated area of ​​population crisis, with poor land and low output, and each one is still very capable of giving birth.

In addition to these, Japan, a small place, has gathered 150 million people, and South Korea has also exceeded 100 million. Many countries such as Southeast Asia have exceeded the natural carrying capacity of the land! Among them, the most terrifying population growth is Brazil and the United States. Brazil, which once had a population of only 70 to 80 million, now has a population of 300 million; and the United States is not willing to lag behind. The population of less than 500 million has now increased to more than 800 million. Almost the world has reached the limit of carrying capacity.

In short, the common problem now is: the population on the earth is about 7 billion under health, but now the population in the world has exceeded 8 billion! This has also led to the double consumption of energy and resources, and the environment has been further destroyed. 80% of the world's fishing grounds have been exhausted. Both marine ecology and terrestrial ecology have been severely damaged, and humans have crossed the cordon!

Especially as plants decrease, climate warms, Siberian permafrost thaws, hundreds of millions of tons of methane gas below began to slowly be discharged into the atmosphere - a greenhouse gas that is far hundreds of times more than carbon dioxide!

In a word, the earth has a cold, it’s time to cool down!

The four people were having a happy conversation. A loud noise came, and then the voice of the flight attendant came: Are there doctors here and are there doctors present!

"Let's go and take a look." Zhang Jingyuan moved in an instant. Although he was not a doctor, he believed that with the control of acupoints, ordinary minor problems could be temporarily curbed. Anyway, the high-speed rail would only take an hour and a half and you could get to the hospital soon. Moreover, in today's society, if a critical situation occurs, the high-speed rail can apply for a half-way suspension, and mobilize ambulances or even helicopters at the same time. Although this may cause a full-line suspension every time and cause hundreds of millions of losses, it has brought strong public support to the country.

When everyone lined up and arrived in front of the car, I saw a seven or eight-year-old child rolling on the ground in pain. In the middle of winter, he was wearing short-sleeved clothes. Although the train was now on, it was only about 16 degrees. In today's energy crisis, the train heating was not more than 20 degrees, and everything was necessary to create an energy-saving society.

Now, the children on the ground are rolling, sweating profusely and steaming. Next to them, the children's parents are probably in their thirties, but they are already worried and gray in their hair.

"Mom and Dad, it's so hot, I'm so hot."

"Hurry, who brought alcohol or wine!" someone suggested.

"That, you are not allowed to bring alcohol when you get in the car!" It should be an alcoholic who answered this.

"Ah, there is alcohol on the train, I'll get it right away!" The crew member left it aside.

"Use cool water first!" Although everyone has no doctors, knowledge is popularized today and there is still general emergency aid knowledge.

"I brought mineral water. Quickly, can I pour it directly on my child?"

There was noisy on the scene, but everyone was discussing how to treat it. Overall, the social atmosphere has changed today, mainly because China has entered the scope of developed countries and no longer has to work hard to develop as hard as before, and everyone's life is much easier.

"This is, the innate pure yang body!" Zhang Jingyuan exclaimed. This kind of physique can be seen on earth, and more importantly, he was encountered by himself!

"What is the innate pure yang body?" Fang Qingshan asked softly.

"Let's go back and save the person first!" Zhang Jingyuan finished speaking, and took a big step out. The situation was very critical. He actually wanted to use alcohol and cold water to cool it down. This was tantamount to sprinkling cold water on a piece of burning steel, which would harm the child. "Stop! Don't pour cold water!" Zhang Jingyuan took a quick step and accurately held the enthusiastic person, "Brother, what would happen if he poured cold water on a red-burned stone?"

Zhang Jingyuan briefly explained that after all, they are saving people kindly, and they cannot hurt the other person's heart. The interpersonal relationships in this society are still very fragile and require careful maintenance.

"Oh, sorry. Just thinking about saving people, it seems that they have to be a doctor. Is the little brother from the medical school?" I found someone who is a middle-aged man in his thirties, but he is obviously a person with a good life.

"Brother, let's talk later. I'll take a look at the child first." The last sentence was also said to the child's parents.

"Please, please..." The child's parents were already super anxious, like ants on a hot pan.

The innate pure yang body is a genius physique in the prehistoric world, and at least it can ensure that practitioners quickly enter the level of golden elixir. However, from ordinary life to golden elixir stage is the first threshold for practice. In theory, it is the development from nothing to something, and it is also the biggest threshold. Once such people are discovered, they will be robbed.

However, such a physique is also a torment for children. Generally speaking, the human body is balanced with yin and yang. Now that the balance of yin and yang is broken, it will bring huge pressure to people. This pressure is manifested in the pure yin body, cold and frozen, and the pure yang body is dry and hot. Some pure yang bodies can even boil water! Of course, it is already in danger to reach the state of freezing or boiling water.

But in any case, the so-called dryness and heat are not actually real heat, it is just an external manifestation of energy imbalance. Just like flames, they actually do not exist, they are just an external manifestation of violently moving particles. In this case, one is to extract yang energy, and the other is to inject yin energy. Of course, this yin energy and yang energy refer to the yin energy, not the yin energy of ghost energy, nor the yang energy of fire, but more of a breath of life. However, such "symptoms" are unsolvable on the earth!

However, the practice of extracting yang energy will reduce the child's physical fitness, so what Zhang Jingyuan can do is to inject yin energy. The main reason is that Zhang Jingyuan likes him. In this situation, this will is worth cultivating!

Zhang Jingyuan flew his hands and kept slapping the acupoints. At the same time, the true qi that had just reached the third level of Qi training in his body was constantly converted into yin energy through specific techniques and injected into the child's body.

One minute later, the child's redness and heat disappeared, and his body temperature was restored to normal people. However, Zhang Jingyuan was tired and sweaty, his face was a little pale, and he almost used up all his true energy.

"Thank you uncle." The seven or eight-year-old child has a pale face and thin skin, which is the delay of the disease.

"Thank you, thank you guy, thank you guy." The child's father looked excited. The mother was also constantly thanking him.

"Alcohol is coming, alcohol is coming." The flight attendant ran over in panic.

"I'll do it." Zhang Jingyuan took out alcohol and applied it to the child's palms, soles and mind. "Brother, you can apply alcohol to the child like this first. Even if the child is cold, don't break it. Don't be afraid of being cold, just wear more clothes. After getting off the car, it's a bit inconvenient."

"Thank you, thank you."
