Since the nine ethnic groups of haotianjie discovered the existence of the human world and knew that the human world and haotianjie can freely enter the human world through the space tunnel, they have never wanted to give up trying to conquer the human world and plant the Mayan Sacred Tree.

The legendary Mayan Sacred Tree is the tree of life recorded in the Bible.

For thousands of years, the protoss, as the master of the nine races, did not support the race of haotianjie to invade the human world.

On the one hand, the purpose of the protoss Xuancheng is to avoid the destruction of life. Everything in the human world also has life. If war is launched at will, it will inevitably lead to the destruction and extinction of most species in the human world.

Although it sounds good, the protoss also have their own selfishness!

For a long time, the protoss has enjoyed absolute authority among the nine families, relying on the Mayan Sacred Tree.

Although the other eight ethnic groups also have Mayan Sacred trees, the problem is that the Mayan Sacred trees in the hands of other ethnic groups are cultivated by using the seeds of the Mayan Sacred Tree of the divine family.

In other words, the Mayan Sacred Tree in the hands of the sacred tree is Lao Tzu level, while the Mayan Sacred Tree in the hands of the other eight ethnic groups is son level.

This caused the Mayan Sacred Tree in the hands of the protoss to get much more Mayan fruits than the other eight tribes combined.

In the Haotian world, the yield of Maya fruits represents the strength and prosperity of a race.

Because as long as we have more fruits of the Mayan Sacred Tree, we can cultivate more people with super long wisdom and power, and after taking the Mayan fruits, the life expectancy will increase, which is also the reason why all races in Haotian world flock to the Mayan Sacred Tree.

But the Mayan Sacred Tree is not like the trees planted in the human world. The general tree species absorb the nutrients in the soil and accept the sun, rain and dew, so that they can grow.

But the Mayan Sacred Tree is not like this. The Mayan Sacred Tree is regarded as a God among the nine races. Although it is a plant, it has a high degree of wisdom. Although I can't speak, I can feel all kinds of climate changes in the whole Haotian world.

Moreover, the Mayan tree absorbs the energy inside the planet, which is absorbed by the Mayan tree in various forms.

For example, the root of the Mayan Sacred Tree has actually gone deep into the earth's core of the planet to absorb energy from the earth's core for growth.

Moreover, the Mayan Sacred Tree will also absorb the nutrients gathered in the sky, such as sunlight and energy in the clouds.

If more fruits of the Mayan Sacred Tree are mined, the Mayan Sacred Tree will over absorb the energy of the planet, resulting in the depletion of energy in a region.

The monster, blood, ice and Ming in the Haotian kingdom all over exploited Maya fruits for the expansion of the ethnic group, trying to fight against the protoss, and finally led to the survival of the territory without grass for thousands of years.

For a planet, energy is in a state of gradual circulation. If the land energy is exhausted, it needs thousands of years of slow nourishment to recover.

Except for the protoss, all other races, due to over exploitation of Mayan fruits, led to the rapid decline of their territory, and the subsequent reduction is the number of Mayan fruits. Therefore, these races have to keep their eyes on the human world!

Because the human world is the only planet suitable for planting Mayan Sacred trees.

The main purpose of the protoss to prevent other races from invading the human world is to maintain its hegemony all the time.

If other races really plant the Mayan Sacred Tree in the human world, they will get a lot of fruit of the Mayan Sacred Tree, and the status of the protoss will become precarious at that time.

In order to ensure that the protoss has always been in an absolute notification position, the protoss must prevent other races from invading the human world.

Tracing back to the domestic history, as early as 5000 years ago, the protoss fought openly and secretly with the invading race for the sake of the human world, guarding the human world.

But in fact, about 10000 years ago, the ice tribe of haotianjie attacked the human world in a large area, which led to the European continent into a short ice age.

Later, the four royal families protecting the protoss launched a counterattack against the ice family in the human world and killed the ice emperor of the ice family, which was regarded as the formal end of this small-scale but extremely tragic war.

Because mankind had not invented words at that time, the war was not included in the annals in the form of myth.

However, with the gradual increase in the number of humans, this higher intelligent creature on the earth has increasingly worried the races who want to occupy the human world.

With the development of the times, human beings are destined to master advanced science and technology. If they can't occupy the human world when they are backward, it will become more and more difficult with the passage of time!

When human civilization developed to 3000 B.C., the demons, demons and blood races invaded the human world again.

But these plans were finally crushed by the protoss!

In order to prevent other races from coveting the human world, the protoss had to seal the space tunnel between the Haotian world and the human world, so that other races in the Haotian world could not enter the human world.

Among the six miraculous Xuanmen, only the miraculous Xuanmen in the protoss territory are in the state of development for the protoss to enter the human world.

The protoss is also aware of a problem, that is, sooner or later, science and technology can be developed enough to discover the existence of the Haotian world. In order to make the human world more stable, the protoss decided to give human culture and faith.

Accept the protoss culture directly, but it belongs to our Chinese civilization! In China's thousands of years of historical civilization, countless educators and thinkers have emerged.

Both Confucius and Laozi are actually people who have passed through the Protoss. They left far-reaching civilization in the human world to inspire human thought and wisdom.

For example, Tao Te Ching written by Lao Tzu not only contains the truth of being alive, but also feels the existence of the macro universe from the micro perspective of human beings.

More than 3000 years ago, human beings did not have the thinking of hiding the opportunity of the universe, but it can be found everywhere in the domestic historical books!

Although some Chinese people now say that there are some peerless martial arts secrets in the Tao Te Ching, it's pure nonsense. However, if the Tao Te Ching is really popularized all over the world, all countries in the world are doomed not to have a war of aggression.

This is also the reason and reason why, throughout China's history and civilization, the more prosperous the dynasty, there has been no invasion of other countries, and has been living in harmony with the surrounding large and small countries.

Compared with the domestic civilization given by the protoss, what the protoss gives to foreign countries is advanced technology.
