The oxygen tubes and oxygen masks in the space backpack were left over from the last time Huo Yu went to sea to explore the sunken ship.
At that time, in order to prevent running out of oxygen, Huo Yu bought several cans in the system mall. They kept them in his space backpack and never had a chance to use them.
Unexpectedly, by chance, it would come in handy here.
Ling Ran breathed in the normal concentration of oxygen in the oxygen tank for a while, and his complexion became visibly better.
Just in case, Huo Yu and Bai Xiaomo also swallowed two vitamin E pills to prevent Bu Ling and Chenchen from getting into an oxygen-drunk state later.
The symptoms of being drunk on oxygen are not terrible, but if three people are drunk on oxygen at this juncture, something serious will happen.
I don't know if Xiaoyu and a wolf can carry all three of them out of the cave.
After Ling Ran's condition improved, he also began to help Huo Yu analyze the situation:
"The current situation is obvious. The oxygen concentration here is much higher than the outside world. People hiding in the island should be supplying oxygen inside."
Bai Xiaomo's big eyes flashed and he asked curiously: "Why do you need oxygen?"
"High oxygen levels mean that plants are lush and animals have enough food. Sufficient oxygen can support a stronger metabolism, so animals can have the physical strength to support a larger body size."
Ling Ran's condition was much better, so he asked Bai Xiaomo for some information.
"That's right." Bai Xiaomo nodded equally seriously, "What do you mean by saying a lot? I don't understand."
Ling Ran fell silent as if he had been hit by Galen's Q skill.
Huo Yu rolled his eyes and continued Ling Ran's words: "The larger the animal, the average oxygen consumption should be more."
"This shows that there may be a large oxygen supply device deep in the island."
"The reason why a higher concentration of oxygen needs to be supplied is because there may be extremely large animals on the island, or it can be said to be dinosaurs..."
As soon as these words were spoken, the three of them received a Q skill each and fell into silence.
There are various indications that the dinosaur island we are on is not only filled with ultra-small dinosaur clones such as Compsognathus, but also very likely giant dinosaurs such as Brontosaurus, Giganotosaurus, and Argentinosaurus.
The largest known dinosaur that has ever existed on Blue Star is Amphoraeus fragilis, which is 35 meters long. Its maximum weight is much larger than the blue whale, about 220 tons.
The blue whale weighs 181 tons. Such a huge weight requires it to rely on the pressure of the water to survive. From this, you can imagine how terrifying dinosaurs on land that are larger than the blue whale must be.
By the way, the blue whale also has the largest reproductive organs in the world, with a length of up to 2.4 meters.
Tsk...so envious...bah bah bah.
Of course, because the dinosaur fossils currently available are incomplete, Amphoraeus fragilis cannot yet be certified as the largest dinosaur.
It also has many competitors, such as Gigantosaurus.
However, due to incomplete preservation of fossils, the mainstream conclusion in the dinosaurian community is still that Amphoraeus fragilis was the largest dinosaur.
In any case, once this giant dinosaur is successfully cloned by an illegal organization and successfully creates a living body, it will be a disaster for Huo Yu and others.
The current attack methods of Huoyu seem to be diverse, but in fact it is difficult to cause actual damage to such a behemoth, and even breaking through their skin defense is very difficult.
"That's wrong." Bai Xiaomo suddenly said, "If the oxygen concentration in the island is so high, how can those humans survive?"
Huo Yu glanced at her with relief. This girl finally knew how to use her brain.
Although she didn't move much, she still moved. Otherwise, if it continued like this, Huo Yu would be afraid that she would get Alzheimer's syndrome.
Thinking of this, Huo Yu explained patiently:
"The oxygen concentration of blue stars during the Jurassic period was 15-21%, while during the Cretaceous period it reached 21-26%. The oxygen concentration in the era we live in now is also 21%."
"So, the oxygen content in the dinosaur era was not that high. The situation on the island must be the same. Humans can adapt to living for a long time."
After saying that, he glanced at Ling Ran sympathetically and continued: "It's just that Lao Ling's physical condition is a little worse. He had to work hard all day yesterday before he became intoxicated with oxygen."
Ling Ran scratched his head in embarrassment: "Indeed, it was normal for me to stay up late when I was in the hospital. Although I have adjusted over the past few months, my sub-healthy state cannot be adjusted instantly."
"No matter what," Huo Yu stood up and continued, "We have already come here. We have to continue exploring. If the situation is really dangerous, we can hide in the shelter and wait for rescue to be organized."
Although the live broadcast room yesterday was officially suspended, the news of meeting the dinosaurs should have been conveyed to the outside world.
If the Icekeeper headquarters cannot contact them, they will definitely send the Polar Navy to search. If nothing else, they are already on their way here.
Unless the leader of the Polar Navy is also a spy of an illegal organization, the safety of his group is still guaranteed.
"How is it? Can we continue to move forward?"
Ling Ran put on an oxygen mask, tried to stand up and move a few times, then nodded to Huo Yu:
"Much better, there should be no problem."
Huo Yu patted his shoulder: "If you feel uncomfortable, don't hold back. It's still early anyway, we can take you back."
Ling Ran shook his head, and the voice coming out of the mask was angry: "No, I understand my body, it's okay to continue walking."
Huo Yu saw this and stopped trying to dissuade him. In his opinion, it was not a bad thing to make the team members suffer a little.
The conditions at the 249 scientific research station are so good. In this superior environment, people can easily become inert.
For example, Bai Xiaomo doesn't like to use his brain to begin with, and he became even less willing to use his brain after joining 249...
"To prevent accidents, you'd better put on your oxygen masks from now on. The Jurassic period was not just about high oxygen concentrations, but also all kinds of miasma." Ling Ran suddenly suggested.
Huo Yu Congruliu advised him that although he was confident in his physical strength, it was a good thing to be wary.
The three of them all put on oxygen masks and oxygen bottles on their backs, instantly feeling like a wasteland team.
In order to prevent accidents, Huo Yu also put the pet battle suit on Xiaoyu.
This combat uniform has not been used since it was taken out. The main reason is that most of the battles at the 249 scientific research station are emergencies, and there is no time to put on clothes for the furry children.
The little fish reluctantly put on the emerald green battle suit. Suddenly its wolf ears stood up, and the whole wolf's temperament changed instantly.
"Ouch! (Something's wrong, there's something near us!)"
