With the experience of entering the mysterious space last time, Ling Zikai knew that every two hours, a whirlpool would appear at the entrance of this space. Only at that time jumping into the vortex is the only chance to enter the mysterious space.

Although he didn't know when the whirlpool appeared last time, and how long it would take to open the cave next time, Ling Zikai was not in a hurry, anyway, the waiting time would not exceed two hours.

Seeing that the little lizard was still there and kept scraping the ground of the riverbed with its claws, Ling Zikai scolded with a smile: "Okay, you don't want to toss around there!"

After hearing Ling Zikai's words, the little lizard stopped and looked back. Seeing Ling Zikai sit down on a stone next to the underground river for a long time, he jumped out of the water and ran to his side, looking at him in the darkness with a pair of glowing green eyes in bewilderment.

Ling Zikai grabbed the little lizard, put it on his knees, patted its little head, and said, "Wait here first, and I'll take you in later." It's just that you destroyed everything in it when you were born, so what's the point of going back!"

Thinking that there were so many rare plants growing in that mysterious space at that time, all of which had been destroyed, Ling Zikai still felt extremely heartache in his heart.

The little lizard raised its head when it heard this, revealing a trace of disdain, which seemed to say, isn't it just some grass, what's the pity.

"I warn you, if you find anything inside, you are not allowed to destroy it without my permission. ”

Since the space inside is so mysterious, it must not be as simple as just some exotic grasses growing in it. The last time I went in, I came and went in a hurry, and I didn't carefully explore the situation inside. Now that he has entered this time, Ling Zikai plans to search carefully, maybe there will be new discoveries.

However, the little lizard is not a fuel-efficient lamp, so don't cause an inexplicable storm for yourself at that time, so I gave it a precautionary shot in advance.

The little lizard nodded repeatedly, revealing a well-behaved appearance, as for what will behave at that time, only God knows.

After waiting for more than an hour, a few ripples suddenly rippled on the surface of the flowing water.

Ling Zikai perked up, grabbed the little lizard in his hand, stood up, and came to the seal at the entrance of the cave.

When the whirlpool on the surface of the water became bigger and bigger, and a large amount of flowing water was swept in, Ling Zikai hurriedly jumped down.

Following the flowing water to the clear pool, before it surfaced, the little lizard had already broken free from Ling Zikai's palm, and with a swoop, its body split a waterway, swimming quickly in the pool like a fish in water.

Although the little lizard followed him out of this space after it was born, Ling Zikai faintly felt that it seemed to be very familiar with the situation inside, could it be that there was some kind of inherited memory in the little guy's mind?

Looking at the little lizard that had disappeared in the blink of an eye, Ling Zikai didn't care about it anymore, paddled his limbs, got out of the water, and climbed ashore.

After taking off his wet clothes and pants, wringing out the water, and cooling it on a branch, Ling Zikai glanced around, thinking that he was dazzled, so he subconsciously wiped his eyes.

When he looked around again, an expression of disbelief appeared on his face.

I saw that the shore around the waterhole was full of green grass and flowers, full of vitality, and there was still a scene full of devastation after being destroyed by the hurricane.

How is this possible?

Ling Zikai calculated the time since he left last time, only a little more than a month has passed, even if the environment in the space is very suitable for the growth of plants, but there is always a process for plants to grow.

Especially the few unknown trees ten meters away from him. I remember that it was broken by the hurricane, but now, the broken trunk not only grows new branches, but also very luxuriant, those new branches are more than ten centimeters thick in diameter, up to five or six meters, if in the natural environment, without four or five years, it is impossible to grow.

There is definitely something wrong with the environment in this space!

Ling Zikai calculated that if he used the ancestral god energy himself, he might be able to make the trees grow back to the current scale within a month. But the premise is that these trees must be transformed with the energy of the ancestral gods.

Could it be that there is also an unknown energy element in this space that is no less than the energy of the ancestral god, thus promoting the rapid growth of plants?

Thinking of this, Ling Zikai's mood seemed a little excited.

In the air of this space, he could feel a unique aura that was not found in the outside world. This aura is very similar to the new energy element born on the base of Weiyang Lake, and it is full of vitality.

At the beginning, Ling Zikai thought that the new energy element in the base was formed through the transformation of the ancestral god's energy. But now there is also this similar energy element in this mysterious space, which means that a long time ago, this energy element originally existed in this world, but I don't know when it suddenly disappeared.

This is just like the natural resources on the earth, after being exploited by human beings without restraint, they will one day be depleted. Even if it is a remnant, it has become a rarity.

If it weren't for the fact that the space in front of me was in a closed state, I'm afraid this new energy element would have disappeared long ago.

Thinking of this, Ling Zikai's heart suddenly thought of a question, this space doesn't know how many years it has existed, even if it is in a closed state, but in the long river of years, this new energy element will be slowly consumed, unless it is in a piece of space, this new energy element has formed a balance system of the natural environment, and it will continue to grow in the cycle.

Ling Zikai had the urge to bring Lin Xing'an to this space immediately.

In the field of research on the balance system of the natural environment, Lin Xing'an is an authoritative figure, let him study it. If the mystery can be solved, it will definitely be of great help to the development of the forest farm base.

Of course, this thought only flashed through Ling Zikai's mind.

This space was even more mysterious than the cave of the Nagus tribe ruins, and he didn't want outsiders to know about its existence at all. Although Lin Xing'an is not an outsider, at least it is not the best time to tell him.

Besides, it's just a guess on my part, maybe the reason why there are new energy elements in this space is because of other reasons.

For example, there were a large number of energy stones buried in it, and these energy elements were emitted from the power stones, because of the closed state of the space, so in the long years, these energy stones have not been consumed until now?

Thinking of the possibility of this existence, Ling Zikai subconsciously released the Ancestral God Consciousness, wanting to search carefully in this space to see if he could find some secrets.
