., the fastest update to the latest chapter of my pet beast super fierce!

Ferns are the earliest terrestrial plants on the earth, and they were found in every corner of the earth in ancient times.

The waterweed fern that appeared in front of him at this time is obviously also a fern, but it is a kind of fern that evolved independently from the environment of the subglacial lake.

The dim light in the sub-glacial lake space may be the reason why the sunlight cannot be absorbed. The waterweed fern is very different from the existing ferns on the earth.

Its whole body presents the rare light blue of plants, and the stems are creeping on the ice wall like rhizomes, and the tip of each main stem grows densely broken leaves, like feathers sticking to the ice. Only the buds in the center are curled up with a snail-like spiral pattern.

Pick off a waterweed fern, start it with ice and cold, the root system is also very shallow, and there is...

Damn it!

Shao Zifeng suddenly discovered that among the attributes displayed by the light curtain, the stars representing the quality of this water-grained fern quickly dimmed, and the leaves of the entire plant were also shrinking visible to the naked eye.

Five stars.

Four stars.

In just a few moments, the quality of Shuiwen Fern dropped to three stars.

Without time to explain, Shao Zifeng swept the deer around him, and stuffed the water-weave fern into his mouth with a dazed expression on his face.

The moment the water vein fern enters the fawn's mouth, it releases a milky pure power.

After a short time, the residue of the waterweed fern that shrank completely into a ball was vomited out by the deer.

"Yo!"

The little deer puffed up his cheeks and looked at Shao Zifeng with anger.

"How do you feel? Are there any discomforts?" Shao Zifeng directly ignored Xiaolu's groaning gaze and said with sincere care.

The deer wasn't really angry. Seeing that Shao Zifeng was so sincere, he slowly closed his eyes, and the antlers were faintly fluorescent, and then gently nodded to Shao Zifeng.

"In this case, eat all of these. If you miss it this time, you may not have such a good opportunity in the future."

This is not his nonsense. Although the Antarctic continent claims to have more than 400 subglacial lakes, each subglacial lake is not connected, so these subglacial lakes are more like more than 400 independent small worlds.

No one knows how these independent small worlds have undergone evolution in the past 15 million years. The same organisms may only have a temperature difference of one degree, and the light will be dimmed and the evolution will occur in a completely different direction.

In other words, perhaps this waterweed fern only exists in this subglacial lake. After all, even in the surface world, ferns have evolved 4 classes and more than 12,000 species.

When the deer lowered his head to absorb the water-grain ferns, Shao Zifeng did not wait, but continued to explore nearby.

Because there are too many unknowns in the lake under the ice, Shao Zifeng didn't dare to be too far away from the deer, so he simply hid beside the ice wall and beat.

The little tooth dragon is like a loyal guard, following Shao Zifeng silently, amber looking curiously at this sub-ice lake.

It has never left the nest before, and even after its mother disappeared, it only looked for food nearby. Therefore, every day is new to it now, and it feels very fresh no matter what it sees.

The empty space under the ice lake is not quiet. In addition to the slap of the water coming in the tunnel, the lake itself also makes a rushing sound, and it seems that waves are constantly beating the lakeshore.

As the water vapor on the lake rolled, Xiaoyalong suddenly turned its head, and it felt that something seemed to have disappeared just now.

Xiaoyalong stopped and tilted his head to look into the depths of the water vapor, but he didn't feel that way anymore.

"Little things, there are a few stones here, can you eat them?"

Shao Zifeng's shout sounded from the front, and Xiaoyalong's nictitating membrane blinked twice and recovered.

Stone or something.

It also doesn't eat ducks.

After inquiring about Xiaoyalong, Shao Zifeng regrets that it does not eat rocks.

He squeezed his chin and carefully looked at the slightly obtrusive stones in front of him.

Not only that, but he always felt like he had seen this kind of stone somewhere.

The off-white stones present irregular shapes, with distorted dark-brown patterns distributed on them.

Pattern.

Thinking of this, Shao Zifeng's eyes lit up. Isn't this the kind of stone that he and Xiaolu were looking for?

But then his brows wrinkled again. It stands to reason that in this space where nothing but ice is water, there shouldn't be any such surface rocks.

Did it rush in from the tunnel of ice crystals?

No, the water in the ice crystal tunnel enters the lake directly.

After thinking for a while, Shao Zifeng picked up the stone: "Little thing, have you seen this kind of stone?"

"Guru."

Little Yalong's face was tense, and it was very serious about Shao Zifeng's question. His amber eyes looked at the stone carefully, and after repeated confirmations, he nodded slowly.

Stone hammer!

It is indeed the kind of stone on the surface!

Has anyone else been here?

But even if someone has come, who would bring this kind of stone in.

Is it someone who thinks this is a fossil like him? The problem is that no one is so stupid, right?

what.

It always feels weird.

Just when he was thinking about it, the deer came to him, rubbed his head against Shao Zifeng and looked at the stones in his hand curiously.

"Is it all absorbed?" Shao Zifeng put the stone down and touched its corners. "Let's continue to find out if there is an exit."

"Yeah~"

Seeing Shao Zifeng's movements, Xiaoyalong stretched out his short forelimbs, trying to feel if he had any horns...

Ok.

Untouchable.

Then, accompanied by Xiaolu and Xiaoyalong, Shao Zifeng spent a long time looking around the Bingxia Lake.

There are gains, but there is no clue about the exit that I want to find.

Perhaps it is because the area of ​​this subglacial lake is too small Except for a few clumps of waterweed ferns, no traces of other plants and animals have been found.

In addition, Shao Zifeng also found a tunnel of ice crystals on the ice wall, in which water continuously flows into the lake.

The deer used vines to send him up and took a look. The two tunnels were the same as the one they came in. They were steep and smooth, without any borrowing points to climb.

After returning to the origin, Shao Zifeng sat cross-legged on the ground, with the patterned stone in front of him, and he looked a little sad.

The hunger feeling relieved by eating fruit before entering, as the physical exhaustion hits again like a surge.

The little deer didn't know how to comfort him, but obediently knelt down beside him and put his head on Shao Zifeng's shoulders. The antler pieces bloomed with a few illusory flowers, exuding a relaxing fragrance.

Smelling the scent of flowers, the tired Shao Zifeng relaxes and doesn't think about anything.

The lake under the ice was full of water vapor, and the lake below made a clattering clatter.

The little tooth dragon who is idle is not noisy, and the amber eyes are staring in the direction just now.

Wow!

A slight rhythm of water.

Xiaoyalong's pupils shrank, and it saw the clouds roll again, and something flashed by again.

(Ps: Some readers questioned yesterday's "Shao Zifeng guessed that the "primitive water" will not choke water because of the high oxygen content". I saw that this was raised when I checked the information. Although there are some popular science below, but But I find this statement very interesting, simply adding this setting to the "primitive water" in the article.

Finally, even if you really get to the sub-glacial lake one day, don't try to breathe in the water! It's going to die! !

Then, I will go back to my hometown to sweep the grave tomorrow, and try to come back as soon as possible. If you are too late, just ask for a day off here in advance, and then you won’t ask for leave again this month! )
