The fatty and Dodge basically agreed with Zoe's idea, but Lewand was still skeptical of the so-called "survival of the fittest" viewpoint.

Of course, this was also related to the fact that Lewand had been fighting alone in different simulated worlds in this space, without connecting them into a line to systematically analyze them.

The fatty had a familiar feeling, and he proposed his own idea from the environmental information fed back by the crystal grid: "I always feel that this place is a bit like the previous Observer Hub."

This sentence reminded Lewand, who took a closer look and, sure enough, it was quite similar.

Lewand suddenly panicked, his eyes filled with fear, and then he stood there blankly, his expression grave, as if he were thinking about something.

Seeing this, Zoe asked Lewand, "What's wrong?"

Lewand shook his head: "I'm worried about running into the Observers. What should we do then..."

The fatty interrupted Lewand's wild thoughts in a carefree manner: "Hey, I say, brother Lewand, don't be so suspicious here. Who has the Observers working twenty-four hours a day? We have to abide by labor laws here too, don't we? You hurry up and lead the way. Let's find our way back before the Observers start working."

The fatty held his breath and rattled off a string of words. His face turned red from holding his breath, and he coughed non-stop. While coughing, he covered his wound with his hand and frowned.

Zoe quickly told the fatty to stop talking nonsense and take a break.

However, the fatty's words were indeed effective. It was better to move around and find a way out than to stay here.

This time, Lewand regained his energy and led the three forward bravely.

The fatty couldn't keep up with Lewand's speed, so Dodge came to cooperate with Zoe to support the fatty and slightly accelerated.

As the surrounding crystal grids changed constantly during the journey, Zoe discovered that the simulated world dominated by plants had been completely destroyed.

The evolutionary process of plants was biased towards the competition for resources. Talent points were added to the plunder of natural resources, the roots became thicker, and the branches and leaves became more luxuriant.

This meant that they had no way to move.

Moreover, during the plant reproduction process, their next generation would also compete for resources, thus entering a vicious cycle.

Instinctive reproduction and instinctive competition for resources ultimately broke the carbon-oxygen balance in the environment, and all the plants died in a short period of time.

With the death of the plants, a large number of plant debris became food for some microorganisms.

A new round of evolution was taking place in the simulated world...

The fatty was supported by the two, and although he walked faster, his physical condition still did not allow it. He felt very uncomfortable, and he said to Zoe and Dodge beside him: "Pay attention to the surrounding crystal grids. If you find the shadows of Jennifer and Derek, tell me. I can't see them all by myself."

The fatty was still worried about Jennifer's situation. They hadn't encountered Jennifer since Zoe and Jennifer separated. The longer the time dragged on, the worse Jennifer's situation would be. This was something everyone knew.

Furthermore, they simply didn't know why they were doing simulated evolution experiments here. And each world was relatively independent, with very precise control of variables and no human interference.

If this was really an experiment, what results did the "person" conducting the experiment want to obtain through the experiment?

The journey continued, and some of the marine creatures continued to dominate in the ocean, while others chose to land on shore.

The creatures that landed on shore began a different evolutionary journey.

Zoe discovered that the evolutionary speed of the creatures in the simulated world was very fast. A process that would take tens of thousands of years of natural selection and evolution on Earth could be completed rapidly in just two or three generations here.

Among them, Zoe saw many creatures that she had not seen in previous textbooks and history books.

The magical randomness opened Zoe's eyes. Later, she even saw a world completely ruled by birds.

However, the evolution of the world dominated by birds did not go as smoothly as imagined. The nimble birds were unwilling to give up their ability to fly freely. To roam the sky, they had to control their own weight, and their bones did not undergo evolution that was conducive to brain development.

The birds' movements were more agile, and their hunting actions were more ferocious. At the top of the food chain, they had no natural enemies.

Eventually, the evolutionary process of the birds slowed down.

The world dominated by birds was quiet and peaceful.

Zoe thought that if the world had no disputes, it would be nice to continue to exist quietly and peacefully like the bird world.

Just as Zoe was fantasizing, a raging fire suddenly broke out in the bird world. All the trees were burned to the ground, the birds' feathers were invaded by the fire, and the birds' homes were reduced to ashes. They could only wander above the forest, but there was an invisible barrier in the blue sky that blocked their last chance of survival. Under the scorching smoke, the birds' beautiful feathers stuck together and turned into a pile of black burnt feathers.

They lost their balance and eventually fell from the sky, buried in the sea of fire.

Seeing this scene in front of her, Zoe asked Lewand: "The birds here were living well, why did a fire suddenly break out and destroy everything?"

Lewand replied: "Actually, I'm not very clear about the reason either. If you use your 'evolutionary viewpoint' to explain it, it's that if the creatures in the simulated world no longer have the possibility of 'evolution', then the experiment will be terminated, and the space of the simulated world will be reorganized to create a new world."

"Petri dish..." Zoe murmured.
