The ancient intelligent life that appeared on the earth was similar in appearance to modern humans.

However, Lu Yuan still easily discovered the difference between them and modern humans.

Perhaps it was because the Earth was larger than the modern one in this era, so the gravitational pull was stronger.

The physical fitness of these human beings is far stronger than that of later generations.

And over time, these humans also began to change.

They gradually developed into four different races.

From their appearance, according to the description in the novel, Lu Yuan named these four races dwarves, humans, elves and orcs.

These four races also gradually developed different civilizations.

The dwarves have clearly embarked on the path of technological civilization, and they have created all kinds of magical high-tech products.

Other races are not far behind, the human race has gradually embarked on the path of cultivation, and in Lu Yuan's opinion, they should be the origin of Qi practitioners.

The elves, on the other hand, have embarked on the path of biotechnology, creating all kinds of artificial life.

The orcs have embarked on the path of pursuing their own power, and Lu Yuan believes that they should be the origin of the Great Witch.

While the Earth is developing, the Titans are also developing rapidly.

There is only one race on Titans, so they are also more united.

In the process of civilization development, the Titans embarked on a path similar to that of the dwarves.

Perhaps because of the smaller gravitational pull of Titans, although the Titans are not more technologically advanced than Earth, they have walked out of their home planet earlier than intelligent life on Earth.

After the Titans left their planet, at first they only obtained some resources on other moons of Saturn.

But as Titan's population grew, tiny Titans simply couldn't continue to support their development.

In this case, the Titans embarked on the path of interstellar colonization.

At this time, intelligent life also appeared on the planets around Titan and developed its own civilization.

However, their level of civilization is significantly lower than that of Titan.

The first to suffer was Europa, who was just beginning to explore beyond his home planet.

From Lu Yuan's point of view, their technological level is about the same as that of the earth 60 years ago, and perhaps even lower.

After all, Europa's gravitational pull is smaller, so it is naturally smaller to walk out of the home planet.

The Europa, who had just started interstellar exploration, was naturally no match for the Titans.

Under the attack of the Titans' overwhelming spaceships, Europa soon became a colony of the Titans.

Then Europa also fell, and after taking control of Europa and Europa, the Titans' technology exploded again.

At the same time, the dwarves finally landed on Mars after leaving Earth.

A fierce war broke out between the tyrannical dwarves and the Martians.

While the war between the dwarves and the Martians was heating up, the Titans had also arrived on Mars.

In the face of emerging enemies, dwarves and Martians recognize the threat posed by the Titans.

Under the pressure of the Titans, the dwarves and Martians, who were originally still in a mess, actually formed an alliance.

After the Dwarves allied themselves with the Martians, the scale of the war grew.

Seeing that they could not attack Mars for a long time, the Titans decided to burn the war to Earth, the hometown of the dwarves!

When the confident Titan fleet arrived on Earth, they were greeted first by the elven biological weapons.

Hordes of various biological weapons launched an attack on the Titans.

Looking at the biological weapons of the elves, Lu Yuan couldn't help but think of the "Zerg"!

The biological weapons cultivated by the elves really look like the Zerg in the game.

It's just that these zergs don't have the ability to reproduce themselves, and they need to be cultivated by the elves in special ways.

After a tough battle, the Titan fleet finally won a tough victory.

It's a pity that before they had time to celebrate, they ushered in a devastating blow!

In the face of an alien attack, the four major races on Earth joined forces for the first time.

The Terrans and Orcs also sent their own high-end combat power.

The Qi Trainers of the Terran Race and the Berserkers of the Orc Race actually rushed directly into the fleet of the Titans.

In the blink of an eye, the mighty Titan fleet was in the face of annihilation.

After the destruction of the Titans' fleet, the four major races of the Earth joined forces to launch an attack on Titans.

Lu Yuan thought at this time that the intelligent housekeeper had mentioned that the first generation of human beings was destroyed because of interstellar wars.

But in the current situation, it should be impossible for the Titans to defeat the earth.

In Lu Yuan's stunned effort, the army composed of Earth and Martians has arrived at Titan.

After a great battle, the Titans chose to surrender.

Subsequently, the Earth Alliance conquered Drow Venus and Venus. The entire solar system was unified.

After unification, the solar system developed very quickly.

Lu Yuan saw that one starship after another was being built continuously.

The civilization of the solar system gradually flew out of the solar system and marched towards the broader cosmic space.

Lu Yuan felt like he was watching a one-step movie at this time.

As the plot develops, he gradually sees all kinds of intelligent life.

In this process, Lu Yuan felt that he seemed to be slowly integrating into it.

On this day, a huge starship entered the solar system.

After entering the solar system, the spacecraft directly broadcast to everyone in the solar system.

On the radio, they claim to be the destroyer civilization, and they only give the people of the solar system two choices, surrender or perish.

The civilization of the solar system, led by the four major races of the earth, is naturally unwilling to surrender like this.

The major fleets of the solar system, as well as the Qi Trainers and Berserkers, attacked with all their might, and finally repelled the invading enemy after a lot of fighting.

The enemy's starship was destroyed, but a small ship escaped from the solar system.

While the civilizations of the solar system were cheering for victory, a greater threat had arrived, and Lu Yuan found that a more powerful fleet in the void was heading towards the solar system......

Under the pressure of survival, the major races of the solar system work together to defend the solar system to the death.

But the enemy is too powerful, and the other party is obviously much higher than the civilization of the solar system in terms of technology.

Solar system civilizations can only rely on Qi Practitioners and Berserkers to inflict damage on their enemies.

But it takes too long to train a Qi Practitioner or Berserker.

If it continues like this, sooner or later the solar system will not be able to hold on.

At this time, the elves stepped forward, and they desperately developed biotechnology, and finally created a biological weapon that could feed on the planet and continue to reproduce.

After the appearance of these biological weapons, they were quickly thrown into the battlefield.

It's a pity that the elves didn't expect that the weapon they created would eventually get out of control.

After the outsiders were repulsed, these biological weapons gradually broke free from the control of the elves.

Out-of-control biological weapons begin to attack the major races......
