On Earth, the volume of oxygen in the air accounts for about 20.95%, but this is not the case on this planet, and the final volume of oxygen is about 24.37% after the method of burning and draining the water by Xu Hang candles!
Living in the air with such a concentration of oxygen has the consequence that the metabolism is faster, the digestion rate is increased, and the waste is secreted more.
This leads to species diversity and natural selectivity.
When organisms adapt to the environment, the body structure will unconsciously change in the direction of adapting to the environment, because the metabolism is too fast, this cycle is greatly shortened, so the organisms living in such an environment have a higher probability of mutation, they have more possibilities!
Living in close to a quarter of the oxygen volume, Xu Hang soon found that his ironclad soldier's wounds were healing far faster than he had imagined.
According to Xu Hang's original estimate, after being vaccinated, it will take at least two to three weeks for the soldiers to recuperate and restore their physical functions to their peak state, and if you add the time to get familiar with the pterodactyl, it will take almost a month!
But now it's only been a few days, and the soldiers are already able to walk alive, their severed limbs not being reborn, but the rest of their limbs have grown into new tissue.
Those iron-blooded men couldn't help but envy the soldiers who were afraid of pain, for example, someone was bitten on the arm by a pterodactyl, and he was infected during the bandaging process, and he should have been cut off so as not to affect the whole body, but this soldier was afraid of pain and was reluctant to cut it.
After Xu Hang sent the therapeutic medicine, after a few days of recuperation, the infected tissue has grown new muscles, and it will not take long to recover as before, without cutting off hands and feet.
"It seems that the recovery speed of the injury is faster, this should not be my exclusive use, it is caused by the environment on this planet."
Xu Hang sighed, his mood was a little complicated, and he didn't know whether he should be happy or disappointed.
For those soldiers who have overdrawn their vitality, what they need most is high-energy and high-nutrient food, which is not difficult for Xu Hang.
After a few days of training, some soldiers have overcome their fears and began to hook up with their fancy pterosaurs, whether it is with food or coercion, after getting acquainted, they can ride on the pterosaur and experience the excitement of soaring in the sky and seeing the mountains.
In four days, a total of 233 soldiers preliminarily completed the run-in, and under the leadership of Xu Hang, they brought back all the materials of the werewolf tribe, including nutritious food.
These soldiers were fortunate enough to see the tragic situation of the werewolf tribe, although they didn't know who did it, but they thought of Xu Hang for the first time, and it seemed that only this might best explain Xu Hang's whereabouts a few days ago.
After thinking about this, I couldn't help but admire and fear Xu Hang even more in my heart.
After eating the nutritious meat products brought from Miska City by the werewolf tribe, the soldiers who had overdrawn their vitality recovered at a speed visible to the naked eye, their bodies gradually plumped, and their hair turned black.
Even Xu Hang had to admit that the food of the werewolf tribe was indeed nutritious.
Many of the meat products in it were something he had never seen before, and the cans were painted with bottlenose dolphins, titan giant ants, agate snails, saber-toothed frogfish and other creatures that looked very strange, but all of them were creatures with extremely high protein content.
Holding back the discomfort in his heart, Xu Hang swallowed the entire Titan Giant Ant, an animal similar to an ant but huge in size, and he immediately felt a strange energy emanating from his body.
Obviously, he was already an intermediate-level lifeform, and even his physical strength was the strength of ten people, but Xu Hang still felt a little different, there seemed to be a stream of heat in his body, constantly impacting some kind of barrier.
Seeing this, Xu Hang's expression perked up, he thought that since his physical strength reached the strength of ten people, he could no longer improve, with the passage of time, Xu Hang knew that he was not a person from this world, and some structures of his body were incompatible with the world, so it was difficult to improve, and over time, his thoughts in this area would fade, and he would wholeheartedly improve his spiritual strength.
If there is the slightest opportunity to increase the strength of the flesh, who will give it up?
After all, a stronger body, more physical energy, means that you can be stronger.
Now that after eating food of a higher energy level, he found that his physical strength seemed to be showing signs of breaking through the shackles, how could Xu Hang not be excited?
He immediately put down the chores in his hand and tried several nutritious foods, but unfortunately not everything could help him break through the shackles, and even ate too much, even the Titan giant ant lost its due effect.
"It's still a little closer, if there is a higher energy level of food, it only takes a hundred catties, and I can break through the power of ten people!
I don't know what will happen after the breakthrough, ten times a night, ten hours each time?
Going out must fascinate thousands of girls?
” Xu Hang smashed his mouth with some regret, and became more determined to annex Miska City, with the air fleet, he would not be able to break through this city with a long heritage. …… A week later, at the cost of a large amount of supplies, all the soldiers successfully recovered to their peak, and they were very grateful to Xu Hang for causing all this, and did not disobey Xu Hang's orders in the slightest.
There were more than 1,200 people in total, all of whom had found their favorite pterosaurs, and under the training of the apes, they became familiar with the pterosaurs as quickly as possible and trained their ability to fight in the air.
Because they have become the Air Force, their previous weapons have lost their effectiveness and have to be replaced with standard equipment in the air.
In this world full of spiritual power, gunpowder is no better than cold weapons, at least there is no need to worry about the risk of suddenly detonating and killing yourself.
After several hours of discussion with the ape Fanner, they settled on the army's universal equipment, similar to the javelin, with sharp tips at the ends and a thick middle to hold in their hands.
Most of the time, this weapon is disposable, because it is too inconvenient to recycle.
Imagine that after discovering the target, thousands of pterosaurs carrying soldiers flew towards the target area at a speed close to the speed of sound, and at such a speed, the soldiers threw out the javelins in their hands, and under the terrifying acceleration, even a steel plate with a thickness of one meter could penetrate it!
Because the speed of the javelin is too fast, it is difficult for even a mid-level lifeform to stop it.
Xu Hang once tried, if all these javelins were shot at him, with his spiritual power, he could only break three hundred javelins, and in the face of the remaining part, he could only temporarily retreat.
He couldn't even face the javelin's edge, let alone other low-level lifeforms.
Xu Hang couldn't help but be full of longing for the future.
It's just that training such a spearman is not an easy task, first of all, there must be plenty of time and a large number of javelins, and the matter of building javelins is imminent!
