I have countless cultivation hours

“This girl, it seems that she is really afraid, forget it, sleep at the door, just sleep at the door, as long as you don’t disturb me.” Listening to the movement outside the door, Ye Han couldn’t help but shake his head.

However, although they can’t sleep in a room together, it’s still no problem to let Ye Xiaonuan sleep at the door.

Ye Han took out his mobile phone and first set an alarm clock at two o’clock in the morning, and then began to continue the unfinished “skin stratum corneum” transformation before.

At this time, being blocked by Ye Xiaonuan at the door of the room, naturally there was no way to go to the bathroom.

However, it does not matter, skin breathing this experiment, without water, can also be carried out.

In this way, time passed little by little, and Ye Han became more and more familiar with the transformation of the stratum corneum of the skin, and even, he had begun to touch the direction of the transformation of the stratum corneum of the skin.

In this process, the efficiency of oxygen absorption by Ye Han’s stratum corneum of the skin is also improved little by little.

Not long after, it increased from 1/160 of the oxygen absorption efficiency of the lungs to about 3% of the oxygen absorption efficiency of the lungs.

In this case, the absorption efficiency of Ye Han’s stratum corneum is already equivalent to 3% of the lungs.

This is undoubtedly a huge breakthrough, although it is still far from enough to meet Ye Han’s physical needs, but at least, it proves that breathing with the skin is feasible.

Next, time passed little by little, and the efficiency of oxygen absorption by Ye Han’s stratum corneum was also slowly but firmly improved.

Gradually, 4%, 5%, 10% … In the end, the oxygen absorption efficiency of Ye Han’s skin stratum corneum even reached about 30% of the oxygen absorption efficiency of the lungs.

Unfortunately, when the efficiency was increased to the equivalent of 30% of the lungs, Ye Han’s transformation of the stratum corneum of the skin also completely reached the bottleneck.

Next, Ye Han experimented for a long time and tried several transformation schemes, but in this process, the oxygen absorption efficiency of the stratum corneum of the skin did not rise but fell.

“Is this the limit?”

“The equivalent of 30% of the oxygen intake efficiency of the lungs is not weak, at least, if it is not a particularly fierce battle, it is enough to keep me in the water for a long time!”

Ye Han touched his chin thoughtfully.

Next, he began to try to close his mouth and nose, and then only use the stratum corneum of the skin for oxygen.

With the closure of his mouth and nose, the oxygen absorbed by Ye Han’s body suddenly decreased significantly, but the remaining oxygen was enough to maintain his body’s needs.

Even if you fight, it doesn’t hurt.

But this kind of battle should not be too fierce, let alone too long.

“It seems that it is still a little bit worse, what I need is that no matter how I fight, it will not affect the oxygen absorption efficiency of my combat power, but next, how to transform?”

Ye Han touched his chin, pondered, and even, took out his mobile phone and began to look for information.

“Yes, the absorption of oxygen with the stratum corneum of the skin relies on the combination of oxygen and water molecules, and the water in my body is limited, which makes my oxygen absorption efficiency have an upper limit, and this upper limit is equivalent to 30% of the lungs…”

“And to improve this efficiency, you have to improve … Well, increase the amount of water in the body? ”

“It all feels a little unreliable.”

Just as Ye Han was thinking bitterly, a sneaky voice suddenly sounded outside the door: “Brother, are you asleep?” I’m like, still a little afraid, can you talk? ”

“I don’t sleep in the middle of the night, what do you say?” Hearing Ye Xiaonuan’s voice, Ye Han said angrily.

“Brother, it’s great that you’re not asleep yet.” Hearing Ye Han’s voice, Ye Xiaonuan said happily.

“……”

“Brother, I can’t sleep either, or let’s find a movie to watch together?”

“……”

“If you don’t speak, I’ll agree to it!”

“……”

“Great, that “Bathroom Horror”, I’ve wanted to watch it for a long time!” Ye Xiaonuan shouted in surprise, and then, soon, the sound of the movie began to sound.

“Lean, this girl, it’s just too much!” Listening to the strange and supernatural sounds outside the door, Ye Han was speechless.

For a while, I couldn’t even remember where I thought before.

“It’s really daring, I watch ghost movies in the middle of the night, and I’m not afraid of provoking real ghosts!” O fearless of the ignorant! ”

Ye Han shook his head, his heart moved, the flesh in his ears had suddenly bulged, and then quickly grew together, and finally closed both ears.

Suddenly, there was silence, and there was no sound.

“Che, want to disturb me thinking about problems? Which is so easy. Ye Han smiled and was about to continue his previous research, but at this moment, Ye Han was suddenly stunned.

“Yes, why am I so stupid, since I can control the meat inside my ear to block the ear, then why can’t I control a layer of meat growing in my nose and then filter oxygen?”

“My purpose is just to facilitate underwater combat!”

“Isn’t it okay to put a meat membrane in your nose that isolates water but filters oxygen?”

Thinking of this, Ye Han immediately cast “Thousand Changes”, controlling the growth of a layer of meat membrane in his nose, and the meat membrane was covered with small holes that were invisible to the naked eye, and these small holes were just enough to let oxygen molecules pass, and as for water molecules and other messy things, they couldn’t pass through.

When everything was done, Ye Han began to try to breathe with his nose and skin, and this attempt, all of a sudden, Ye Han couldn’t help but laugh with satisfaction.

Although the combination of the two is still not as good as pure breathing through the nose, the efficiency is close to 90% under normal circumstances, and in such a situation, no matter how fierce and how long the battle is, there will be no lack of oxygen.
