Once yin and yang are out of balance, they will tip rapidly to one side like a scale.

Wildfires often devastate herbivores first, causing a large number of them to starve to death, followed by a large number of other carnivorous animals.

You might think that after a fire, plants recover, animals can recover as well, and everything can return to normal.

This brings us to the issue of base numbers; each era has its corresponding products.

For example, the oxygen concentration was very high during the Jurassic period, but it also gave rise to a large number of herbivorous and carnivorous dinosaurs weighing tens of tons each.

Their consumption and suppression of plants is only one aspect; the carbon dioxide emissions from a large number of megaorganisms are also enormous.

This carbon dioxide may seem like a problem now, but back then it could reduce oxygen levels to a safe and suitable range.

It can slow down the rate of cellular oxidative division in animals, thus extending their lifespan. This is beneficial in dealing with the problem of low tolerance for sudden environmental changes.

The evolution of life is also a process from simple to complex. The mass extinctions of species before the Cretaceous period were mostly caused by the low tolerance for error between species, which led to severe disasters caused by slight changes in the environment.

Plants and animals in nature are like the two polarities in Tai Chi; they are both opposing yet interdependent, and any change in either one can cause irreparable problems.

Don't assume that only animals go extinct, and that plants won't go extinct if there are many of them. When one side loses its balance, they will also face their own demise.

There have been several well-known mass extinction events in Earth's history, which have often had a huge impact on plants.

For example, the Permian-Triassic extinction event was the largest known mass extinction, in which a large number of plants went extinct due to drastic climate change, volcanic activity, and other factors.

At that time, the eruption of the Siberian Dark Rock volcano released large amounts of greenhouse gases such as carbon dioxide, triggering global warming and ocean acidification, which severely damaged the living environment of many plants.

There was also the Cretaceous-Paleogene extinction event, which led to the extinction of dinosaurs and also caused the disappearance of many plant species.

The dust generated by the impact blocked sunlight, inhibited photosynthesis, prevented plants from growing normally, and ultimately led to the death of a large number of plants.

After the old order collapses, a new order emerges.

This brings us back to a higher level, to the philosophical origin of yin and yang, where the destroyed order is yin and the newly established order is yang.

Balance will reappear, and Yin and Yang will once again be subdivided into two major camps, mutually restraining each other and evolving into more complex and advanced civilizations.

These mass extinction events of plants had a profound impact on the evolution of Earth's ecosystems, prompting the rise of new plant groups and the redistribution of ecological niches.

After half a day of trekking, the sound of birdsong gradually increased.

Perhaps because the birds deliberately avoid those giant mosquitoes, in any case, the area we are in now should be safe for the time being.

But this seemingly endless cliff has already worn down most of our patience. Now, not only do Su Su and Dante feel that this path is impassable, but even I myself am starting to feel uncertain.

But we've already come this far, and now we have absolutely no way back. We really have no choice but to keep going down this path.

Fortunately, after walking for a while, we found a stream flowing down the rock face, forming a channel on the ground before flowing towards a low-lying area.

I think since the water flows to low-lying areas, there must be some kind of pond or pool in front of us.

We've already finished the fruit Top collected, and we've also drunk quite a bit of water along the way. Now we're running low on water and urgently need to find a suitable place to replenish it.

We dare not drink this water directly; we should boil it first to be on the safe side. Like I said, we're escaping for our lives right now, and any unexpected event is something we can't afford.

Dante suggested that we collect some mountain water here, boil it in bamboo tubes, and store it.

However, I think our current water supply can support us for a while longer. When we reach a place with water, we might be lucky enough to encounter some aquatic products such as fish and crabs.

We roasted and ate the last giant frog yesterday, so catching a few fish to have a treat now would be a good option.

After hearing my suggestion, Su Su and Dante agreed that it made sense. The key point was that they themselves were craving fish and hadn't eaten it in a long time, so it would be great if they could get some.

The "looking at plums to quench thirst" method worked very well. After telling the two about going fishing, Su Su and Dante's faces lit up, and the gloom of the past few days was dispelled. They even walked much faster.

That's how people are sometimes; they need a reason to move forward, a reason that can serve as motivation to tirelessly propel humanity forward.

After walking for about fifteen more minutes, we did see a body of water, or more precisely, a long and narrow pool right next to a cliff.

What delighted us even more was that there were actually fish swimming inside, and they looked to be quite large.

Su Su pointed happily at the water and exclaimed,

"Master, Master! Look! There really is a fish here! And it's a really big fish!"

At this moment, Dante frowned and pondered as he looked at the fish in the water. Why did these fish look so familiar?

At that moment, I recognized the fish immediately, and my first thought was that I was very happy.

Seeing these fish is one thing, but what truly makes me happy is something else, though I'm not entirely sure yet.

I pulled Susu away from the water's edge, away from the water's surface.

Su Su was puzzled and asked me why.

I simply said that the water wasn't safe and it would be better to stay away. With that, Dante and I began to examine the pool.

When we arrived at one area of ​​the pool and saw the rocky outcrop extending from the bottom of the water, Dante and I were both struck by a flash of inspiration, and our excitement was impossible to contain.

"Ha ha ha... We're saved, sir, we're saved!" Dante shouted excitedly.

Su Su was completely bewildered. Weren't we still at the bottom of the cliff? How did we suddenly get rescued? Su Su looked at me with a questioning gaze, hoping to get some answers from me.

I smiled and said,

“Susu, Dante is right. Do you remember when I told you about the pool where we encountered the crocodile when we went to find Pat?”

"Ah! This isn't the crocodile-infested pool you were talking about, is it?" Su Su looked up at me in surprise.

I smiled and nodded noncommittally. This is the sinkhole we visited before!
