For example, room-temperature superconducting technology, microwave power transmission technology, ultra-durable and ultra-high conversion rate solar panel technology, controllable nuclear fusion, low-loss dielectric engine technology, etc., which are easily mastered by humans.

These civilizations that have worked hard have all been firmly blocked by invisible walls that may be defects in their own consciousness structures or may be attributed to the external environment.

This wall of sighs is the "upper limit" of intelligent life with different physiological structures, and represents a certain cruel rule of the universe.

Assuming that mankind fails to find a breakthrough in new energy, until it exhausts the fossil fuel resources on the earth, and fails to obtain unlimited energy that is stable, controllable and sufficient to supply the needs of the entire civilization, then mankind's situation will also be dangerous.

Even if there are recyclable energy sources such as wind energy, water energy, and tidal energy, it is useless. Once energy output cannot keep up with social needs, resources will become increasingly scarce, which will inevitably lead to cruel wars for resources, and most of us will perish together.

I am afraid that human beings will not be able to escape the same fate as these extinct civilizations.

Humans once thought they were alone in the universe.

Now it seems that it is completely an illusion caused by ignorance. It was just that we could not see and contact each other before.

As the ultimate idealist philosophy says, "What cannot be seen does not exist."

Human beings' sense of loneliness is based on extremely idealistic concepts.

At a certain stage, this is true.

But at another stage, it failed itself.

Only when you stand at a certain height can you see the mystery of the vast and infinite universe.

Competition in the universe has always existed and is extremely cruel and fierce.

Every race that can escape the shackles of interstellar distance and leave its home star is a lucky person in the universe.

Of course, these lucky ones will all meet a tragic fate.

All races will inevitably fall under the butcher's knife of the compound-eyed ones.

For millions of years, no one has been spared.

People with compound eyes usually don't pay attention to low-end secondary civilizations at all, just like humans never care about an ant nest outside their home.

No one cares whether this nest of ants develops and grows or is destroyed and disappears quietly.

But when the ants mutate, become larger, become more toxic, and may even harm humans, humans will decisively use flamethrowers to feed the nest of ants.

In addition to secondary civilizations, there are more than 20 million planetary systems with special cosmic rules within the territory of the Morrowind Empire that have some reference value at some level.

Human beings have cracked a lot and studied a lot, but I dare say that only 10% of them have been understood in depth enough.
