The so-called driving force of life is the most basic vitality of life that can survive in this world, and it is the purest energy.

Originally, this question of the driving force of rain's life has been discussed by countless civilizations for hundreds of millions of years, or even longer. Just like the earth, human beings have always regarded carbohydrates as the most basic energy for human survival.

Because carbohydrates are the least expensive bioenergy source that the body can break down energy.

For example, in addition to carbohydrates, these energy sources also include fats and proteins. These are some of the most basic elements that make up life.

Generally speaking, when a person is starving, a fat person will endure hunger for a longer time than a thin person.

Of course, this is the general situation. If this person has symptoms such as heart muscle failure, arteriosclerosis, etc., it is difficult to make the nutrients in the body supply quickly, and breaking down fat or protein to absorb energy is tantamount to painting a cake to satisfy hunger, and the effect is minimal.

Because fats are harder to break down, and proteins are harder to be broken down into energy.

These are some of the first superficial understandings of the internal energy channels of the human body.

However, as humans gained more scientific and technological information about advanced civilizations, they began to understand that the genetic energy in the human body is the most critical part of life. It's like the car needs to be refueled to be able to operate, which is basic common sense.

However, if you use gasoline or diesel, you will definitely need maintenance for a long time......

After mankind acquired high-tech civilization, a flying car was developed and replaced with a high-speed engine. At this time, reducing the drive of the engine bearings will greatly increase the life of the car, and the maintenance interval will be greatly extended.

The same goes for it. As humans absorb more of their energy, human scientists have a deeper understanding of the energy that maintains the balance of human life.

In fact, the human body is the same as a car. At first, cars used low-grade energy sources, namely gasoline and diesel. In this process, gasoline and diesel are also purified, and even new energy such as electricity is used with the progress of science and technology.

In fact, for human beings, the real energy lies in genes. This is the core driving force of the human body.

It's like if a car needs wheels to run, there are bearings, engine pistons, and so on on the wheels, all of which are worn and consumed by each other, forming friction. If you remove the wheels and let the car fly directly, you greatly reduce the loss of friction.

The same is true of human life.

With the progress of society, the pollution of the modern earth is also increasing. When humans eat food, they also have to eliminate many unnecessary substances in the food, and even detoxify the pesticides in it. That's where the liver and kidneys come in.

In addition, humans also need to decompose heavy metals, bacteria, and toxins contained in the air and water. As a result, human organs such as liver, lungs, and even the heart are worn out. Over time, aging will occur. That's the danger of food.

Human beings must have enough energy to survive and sustain themselves, but these energies not only do not help human beings grow and evolve normally, but also become a burden on human beings. It was necessary to have a better substance to replace the food that had been consumed by humans before. So health food was born.

However, in the final analysis, health supplements still cannot meet the requirements of human evolution for evolution. Without the emergence of the World Tree, it would have been another thousand years before mankind would have been able to find the concept of the driving force of life.

However, after the emergence of the World Tree, the term life force gradually appeared in the public's sight. Because only the energy of life can enable human beings to continue to evolve.

After Aoki absorbed almost ten tons of low-grade life crystals, after being filtered by the golden ring, more genetic energy and life force were poured into the trunk of the World Tree.

Soon the genetic energy began to repair the gene chain in every cell in the trunk of the World Tree, and even replenished more energy to make it more perfect. In this way, the branches and leaves that grow on top of the World Tree will become stronger.

If the World Tree is getting stronger and stronger. Not to mention that the advancement of the World Tree promotes the evolution of planetary resources, it is said that the World Tree itself will become a huge treasure trove.

Take the trunk of the World Tree, for example.

As the World Tree progresses, the trunk of the World Tree becomes thicker and thicker. It is said that when the World Tree becomes a Sixth Order, the trunk of the World Tree will even become the size of a city, or even the size of a country. It also depends on how many Life Crystals this World Tree absorbs.

According to the information obtained by Aoki about the Elven World, the World Tree in the Elven World was many times larger than the Earth at its strongest. Therefore, if the current Aoki's ontological world tree is compared to the world tree of the seventh or eighth level civilization, it is like the difference between an ant and a heavenly tree.

As Aoki completely digested the life crystals, his main trunk also continued to expand, so that some of the surrounding trees were also absorbed into the World Tree by Aoki, becoming a branch and branch above the World Tree. But even so, these trees still have their own spirituality, and they are even better alive than they used to be.

Just when the World Tree was constantly evolving, Sver Lulu hurriedly took the members of the Sver family and the elves to fly high in the sky in a spaceship, not wanting to affect Aoki's advancement because of his existence.

As a result, the World Tree is getting bigger and bigger, and even expanding. This time, the expansion of the World Tree was enough to make the main trunk of the World Lord expand ten times before it stopped. Today, the trunk of the World Tree is at least two kilometers thick.

However, compared to this, the height of the World Tree has not changed much, it has only doubled from before, that is, it has now grown to a height of 200,000 meters, and it has directly extended its body to the middle layer of the atmosphere (because the earth has become larger, the height of the atmosphere has also expanded dramatically).

I saw that under the attention of humans and primordial beasts all over the world, the World Tree continued to rise, and countless white clouds covered the middle of the World Tree, and it was misty, revealing only the lower half of the World Tree.

As far as the eye can see, the whole tree towers into the sky, the clouds and mountains are covered with fog, and the end is not visible, which is incomparably majestic and magnificent.

Of course, these changes are secondary, and the main thing is that the nature of the entire World Tree has also changed drastically. The bark of the World Tree, which was originally as hard as steel, is now stronger and more durable than the hardest synthesis on Earth.

The thickest branches of the World Tree are hundreds of meters thick. If you take this branch off, you can use it to make automobiles and ships. Such a car can be said to be very strong and durable, there will be no loss of material for a hundred years, and it can automatically absorb all kinds of energy and supplement it to the engine, which can be said to be better than any material produced on the earth.

In addition to this, some sap will flow from the branches of the World Tree. These juices become healing elixirs, and ordinary wounds will heal immediately as soon as they are applied.

The leaves of the World Tree are also very powerful. If you use the leaves of the World Tree to make clothes. Such clothes can not only keep warm and maintain the basic life cycle of life, but also greatly increase the life span of life and enhance their own resistance.

The most peculiar thing is that the vitality fed back by the World Tree to the human race has increased by a hundredfold. It can be said that the life on Earth has increased dramatically, and even the viruses and bacteria on Earth have been strengthened. The life expectancy of human beings has increased from about 200 years to 300 years or more.

These are all superficial changes in the World Tree.

At the root of the World Tree, the changes are no weaker than the changes in the trunk of the World Tree.

While the trunk of the World Tree continued to expand and grow in height, the root system of the Tree of Direct continued to stretch into the ground, even reaching deep into the heart of the planet. However, the roots of more World Trees still entangle the periphery of the Earthheart.

Now Aoki can faintly feel the tremendous energy contained in the heart of the earth. That is, in the future, there will be extraterrestrial civilizations to invade the earth. Even if Audron doesn't need to come out, Aoki can rely on the Heart of the Planet and a large number of warships to protect the safety of the Earth.

In addition, as more of the roots of the World Tree were planted in the heart of the planet, Aoki began to be able to control the energy of the entire planet. In other words, the Earth has now begun to have the initial ability to move in the starry sky without the need for thrusters.
