The climate chamber is a three-layer stack.

When the time was approaching, the first floor of the house was opened. Lao Tianshi, Zhang Zhixiang, and Huang Jin entered with lanterns. The door was closed again, the curtains were lowered, and the wind soon stopped.

The brief air circulation made the smell in the house better, but it was still unpleasant.

The candles in the lantern were still burning, and Zhang Zhixiang thought that if he stayed there for too long, he would run out of oxygen and faint.

None of the three moved.

After waiting for the air flow in the room on this floor to basically stop, which took about a cup of tea, Zhang Yanqi set off. The two of them followed and walked to the south to open the second door. Huang Jin went to lower the curtain himself.

This time I walked to the third door and stopped to wait.

This time, after waiting for a full stick of incense, Zhang Zhixiang felt suffocated, and then Zhang Yanyi opened the buckle of the third door and pushed open a wooden board on the door, revealing a layer of gauze inside, which was faintly visible.

Can see inside.

The three of them stood outside the door, waiting quietly.

Zhang Zhixiang was only curious. Master Tian was very calm, but Huang Jin was very nervous. He clenched his fists and stared at the floor of the inner room with all his concentration, looking at the twelve rhythm tubes.

Time passes slowly.

When Zhang Zhixiang found it more and more difficult to breathe, there was a sudden "pop" sound, and there was even a sound similar to the explosion of gunpowder from the yellow bell. After the bamboo membrane that sealed the hole was broken, ashes burst out all over the room.

, the "buzz" sound was so loud that even the ground seemed to be shaking. Then there was a sudden change, and the remaining eleven rhythmic tubes erupted one after another. Twelve buzzes of different scales sounded in unison, and the sound seemed to hit directly.

Above the soul...

"how come!!"

Huang Jin couldn't hold back and immediately exclaimed. Jia Guan fly ash has always been an effective means of adjusting the calendar. Huang Zhong Palace is the foundation of Lu Lu. One-third of the people in Qin Tian Prison are responsible for this experiment, which is carried out every year.

Correction.

There has never been such a phenomenon in the records of Qin Tian Jian.

This is no longer simply a severe heat followed by a severe cold, but a disorder of the four seasons. This is a sign of the collapse of the earth!

"Brother, what's going on?"

Although Zhang Zhixiang didn't understand, he still felt that something was not good. The Heavenly Master sighed quietly and said: "Things change at the extremes. After the intensity of the cold wave exceeds the norm, the four seasons collapse, drought, floods, earthquakes, locusts, plagues, etc.

Everything will follow.”

"Moreover, it will not be just a few years, but will last for hundreds of years."

"In the past, the end of the Yin and Shang Dynasties, the end of the Eastern Han Dynasty, the end of the Li and Tang Dynasties... all started from this, and the land of China was filled with ten houses and nine empty houses."

What the Heavenly Master saw was the calamity of the disaster on the common people, but Huang Jin was trembling all over, and what he saw was the change of dynasty...

This cold wave is more severe than before. Can the Ming Dynasty survive?

"Old Master!!"

"There is a great heat before a great cold. The stronger the cold wave, the higher the probability of an immortal being born, right?"

Huang Jin looked at Zhang Yanyi, hoping to get the answer he wanted, but there was no expression on the old Heavenly Master's skinny face. He pulled Zhang Zhixiang and turned away, and Cang Qiu's voice fell in Huang Jin's heart: "Heaven's murderous intention

, stars move and change places; the earth sends murderous intentions, dragons and snakes rise from the ground; humans send murderous intentions, heaven and earth turn over and over again; heaven and man unite, and everything is established."

"During this time of great calamity, heaven and man are united."

"How can your majesty only place your hope in immortals?"

Huang Jin woke up suddenly, bowed to the Heavenly Master with a solemn expression, and hurriedly gathered his team to rush back to Kyoto overnight...

Watching the lights in the distance blend into the dark night.

Zhang Zhixiang hesitated to speak several times. He followed along and understood what Huang Jin and Lao Tianshi were talking about.

Little Glacier in Ming and Qing Dynasties.

From the 29th year of Jiajing, that is, 1550 AD, to 1770 AD, there was a long ice age of 220 years. At its most severe, even the Yangtze River would freeze for more than a month. The ice in Dongting Lake could be one foot thick.

It can snow heavily for seven to eight days in the area, and the mountains, rivers, and trees are covered in heavy snow, leaving only white in the eyes...

He was weak in his previous life, but he had an excellent memory and a quiet personality. Apart from practicing martial arts, he mostly spent time reading.

The Heavenly Master said that nine out of ten rooms are empty. It is really not an exaggeration.

The population recorded in the Ming Dynasty records is not the real population, but the number of people the court can collect taxes. This number was the lowest in the first year of Zhengde, which was 46.8 million.

And what is the actual population?

During the stable period of the Republic of China, the population was estimated to be 450 million based on the national production and sales of salt. However, the population statistics in 1950, just after the war ended, was 550 million. It can be seen that the actual population was higher than those estimated based on the production of salt and grain.

After Japan inspected the land in Taiko, it was estimated that the population was 17 million based on grain. The actual population must have exceeded 20 million.

Such a barren island country can support 20 million people. The population of the Ming Dynasty was only 50 to 60 million. Is this credible? In fact, at the end of the Southern Song Dynasty, the population of the south was 100 million, and the Jin Kingdom in the north had another 56 million people.

Ten million, it can be said that with the level of land development at that time, it could feed 150 million people.

During the Ming Dynasty, in-depth development was completed in Fujian and Guangdong and Guangxi, and Yunnan was added. The population should not be less than 200 million.

Xu Wei wrote in "Records on Hukou in Kuaiji County Chronicles" that the number of people who are not naturalized is at least three times the number of people who are naturalized. So, based on the 60.69 million in the sixth year of Wanli, the number of people who can pay taxes is at least 240 million.

What would the actual population be?

Let’s look at the changes in productivity in the late Qing Dynasty and the late Ming Dynasty. Did the Qing Dynasty’s productivity develop? No. Did the Qing Dynasty have lower taxes? No. The Qing Dynasty had corn, potatoes, and sweet potatoes, but the Ming Dynasty did not? Did Zheng He’s voyages to the West really happen?

Didn’t it reach the Americas? Later generations confirmed that the entire map of Kunyu and Ten Thousand Kingdoms was done by the Ming Dynasty...

Well, even if the Ming Dynasty did not pay attention to potatoes, sweet potatoes, and corn.

However, according to statistics in 1949, my country's grain yield per mu was only 68.6 kg/mu. Are the effects of these high-yielding crops really that outstanding? In the book "Research on Grain Yield per Mu in Chinese Dynasties", the average grain yield per mu in the Ming Dynasty was estimated after weighting. It’s 2.31 shi! That’s 316.5 jin!

And how much land did Ming Dynasty have?

In the ninth year of Wanli, Zhang Juzheng measured the land in the country, totaling 707 million acres! In the thirty year of Wanli, it was said that there were 1.161 billion acres! Only based on the ninth year of Wanli.

The annual grain output of the Ming Dynasty was as high as 223.77 billion catties!

In 1949, the per capita ration was 420 kilograms!

How many people can this food feed? Answer: 532.8 million!!

Since the peak population of the Qing Dynasty can exceed 500 million, then the peak population of the Ming Dynasty is 400 million, right? If we take a step back 10,000 steps and fold it in half, it would be 250 million!!

But what about after passing the Little Glacier?

In the eighth year of Shunzhi, "Records of the Qing Dynasty" recorded that the number of Ding was 10.63 million, and in the 39th year of Kangxi it was 20.1 million. Under the Qing system, men were called Ding from the age of 16 to 60, and women were called Kou, so the actual population was higher.

Calculate it can be multiplied by 3, and if it is outrageous, multiplied by 4, then the population in the early Qing Dynasty was only between 32 million and 42 million.

There is a high probability that it will not exceed 40 million...

"Ten rooms and nine empty rooms" has never been a dry adjective, but a real catastrophe. Xiaobinghe is a murderous intention caused by heaven, while the Manchus' entry into the customs is a murderous intention caused by human beings...

It’s truly earth-shaking!

The Ming Dynasty fell in 1644, and the eighth year of Shunzhi was 1651!!!

Zhang Zhixiang knew that man-made disasters were far more harmful than natural disasters, especially when the two were superimposed, it would be a real disaster. However, he wanted to say something or do something, but he didn't know where to start.

The Heavenly Master patted him on the shoulder.

Said: "Don't worry, the whole world is not tied to your shoulders alone, there is no need to bear any burden."

"Senior brother."

Zhang Zhixiang lowered his head and shouted in a low voice. He was a little sad: "In the prosperous age before the catastrophe, every step of our practice was to step on a mountain of corpses and a sea of ​​blood?"

The Heavenly Master was stunned for a moment, and his face became extremely soft.

Looking at Zhang Zhixiang lovingly, he said: "Then bear their fate and go to practice."

"Is that okay? Doesn't Senior Brother often say that the most important thing in spiritual practice is tranquility?"

"You are very quiet now."

"a little confused……"

"Haha, you will understand when you grow up."

"Um."

(ps: In fact, there is no need to worry about the population of the Ming Dynasty. This book sets the peak in the late Wanli period at 400 million. Now in the fifth year of Jiajing, it is about 240 million.)

(ps: During the Chongzhen period, natural disasters and plagues reached their peak. Ten houses in the Central Plains were empty, and the imperial court was too poor and weak to provide relief. In addition, due to war and turmoil, large-scale famine and plague caused heavy population losses. This is the "harmony of nature and man"
