, the pen and ink can communicate with the spirit, and have an effect similar to the stone carvings of the Taixuan Sutra, and can be used to select people with excellent martial arts talents.

Seeing that Henkel was reluctant to accept it, she thought for a while and planned to sell a few paintings from the other party and then donate or rent the rest to top museums in major countries for exhibitions and visits, so as to find some

Cultivation-worthy cultivation seeds.

As far as Zhao Qing knows, there are already many hunters in the Nibelung base dreamland on the other side. They want to expand their own power and begin to train primitive people to practice internal skills. In a normal world, naturally they cannot be too far behind.

.

Speaking of which, through her research on the "actual measurements" of the dream copy and modern archaeological results, she came to a rather startling conclusion about the cultivation of primitive people: primitive humans who were more than 10,000 years old had far more talents in cultivation than modern people.

People are taller, and they are not just one or two points taller.

This may help Zhao Qing indirectly explore the ancient history of the main world, and also have a rough estimate of the birth, average quality, and comprehensive combat power level of the early hybrids in the dragon world.

Here, we have to mention the trend of changes in human brain capacity:

In the past few million years, the brain capacity of early human ancestors experienced a period of rapid growth. The original brain capacity was about 450 ml, and later almost quadrupled until the end of the Paleolithic Age, when new changes occurred.

That is, the brain capacity stopped growing, and instead reached an inflection point and began to show a downward trend.

Over the past tens of thousands of years, the brains of men and women have shrunk by 157 milliliters (9.7%) and 261 milliliters (17.4%) respectively. The decline was particularly significant during the Shang and Zhou dynasties about 3,000 years ago.

The difference in body size is not enough to explain this problem. Although the average weight of humans in the Upper Paleolithic Age was 62.9 kilograms, which is about 4.7 kilograms heavier than the 58.2 kilograms of modern humans, it can only explain a decrease in brain volume of about 20 milliliters.

As we all know, there may be individual differences among the same species, but at the group level, differences in brain volume are strongly correlated with differences in IQ. For example, the relative brain volume of black Africans is significantly smaller than that of East Asians.

In other words, the average intelligence of humans in ancient times was probably much higher than that of modern humans, their energy and energy were more abundant, and their corresponding cultivation talents were probably more outstanding.

Based on the limited information, it is speculated that the main world corresponds to the period of normal history from 20,000 to 30,000 years ago to about 3,000 years ago, which should also be the peak period of spiritual practice. This naturally gave her many additional associations and suspected that there were similar reasons.

In addition to factors such as the massive consumption of rare cultivation resources, what are the other potential reasons that led to the decline of a once extremely powerful cultivation civilization?
