Huang Mingshan had a dream in which his head was pressed into the water and he couldn't breathe.

Huang Mingshan struggled, but still couldn't breathe a breath of air, the feeling of dying, the stimulated Huang Mingshan shouted, finally woke up from the nightmare, and opened his eyes suddenly.

Then

He saw his son, riding on his neck...... Pee~~~

The little bastard laughed at the thief happy.

Huang Mingshan was about to get angry, but he was suddenly stunned.

He carefully sat down with his stupidly happy son in his arms, used a few spells to clean up the stains, lifted the quilt and stood up.

The wife got up, picked up the little son helplessly, and pinched the little guy's nose dotingly, "Naughty!"

"Giggle......" the little one giggled excitedly, as if he was still proud.

After appeasing the little guy, his wife came to Huang Mingshan's side and asked carefully, "What are you thinking?"

Huang Mingshan smiled: "I thought of it, I thought of it!"

"What comes to mind?"

"Something from the research lab. You go to sleep first, I'll go to the research room. Huang Mingshan hastily washed his face, grabbed his clothes, and rushed out.

His wife looked at Huang Mingshan's back and shook her head helplessly, with a happy smile on her face.

Turned his head to look at the wealthy family, looked at the spirit stones in the place and the pills in the cabinet, smiled again, and began to massage and take Peiyuan Dan to the energetic little guy.

While massaging, he said: "Little guy, your father is so hard, you are still making a blame." ”

............

But it was said that Huang Mingshan ran to the research room like a wind, quickly found a pen and paper, and wrote four big words on the paper: gas nutrients!

After admiring himself for a long time, Huang Mingshan began to do research and was busy until dawn, when Zhang Hao and others came.

Huang Mingshan said excitedly to Zhang Hao: "Young Master, I have found the truth!

Zhang Hao took the paper with "gas nutrients" written on it, and looked at Huang Mingshan with some amazement, "Tell me about it." ”

"Last night, I had a dream that I couldn't breathe air, and when I woke up, my youngest son was sitting on my neck and peeing......"

"Poof......

"Haha......"

There was a burst of laughter all around.

Zhang Hao immediately snorted coldly, "If you don't want to hear it, you can leave now, the door is not locked!"

Everyone immediately stopped laughing.

Huang Mingshan sneered and continued: "When I woke up, I was about to get angry, but I suddenly thought that when we usually eat, we have to absorb the nutrients in food. We have to practice, and what we absorb is aura. So when we breathe, do we absorb some kind of nutrient in the air?

This nutrient is active, it burns, it rusts iron, it can provide us with breath!

But it is not particularly active, it needs certain conditions to work.

I had just done another experiment, which was to enclose myself in a small, sealed space, and I breathed hard, and gradually, I felt that the air around me had changed, it had become turbid, and the nutrients in the air had gradually disappeared, and my breathing was becoming more and more rapid, but I could not provide the body with what it needed.

Eventually, I even began to hallucinate, my heart was racing, my body was weak, my mind was confused, and I didn't even have the ability to undo spells.

Fortunately, the spell does not work at this point. ”

Zhang Hao's face became solemn, "Huang Mingshan, in the future, such research must not be carried out alone!"

"Yes. ”

Zhang Hao got up and patted Huang Mingshan on the shoulder, "I know that everyone is now in contact with a strange world, which is the essence of the world. There is also a thirst for understanding the nature of the world.

But this research will not happen overnight.

As the saying goes, if you want to hurry, you can't get there.

To explore the world, you need a method, a mind, not impatience. ”

Huang Mingshan took a few deep breaths, gradually calmed down, his mind became clearer, he thought about it, and said calmly and modestly: "Young master, what I found just now can only be regarded as an ordinary phenomenon, but it can't explain the 'why'. ”

"Just think about it. Zhang Hao nodded with satisfaction, and as he spoke, he wrote the word "oxygen" next to 'gas nutrients'.

"Oxygen, pronounced 'Yang', I invented this new word as a brand new proper noun in order to forever remember today's discoveries.

Huang Mingshan, this word is closed. Perhaps in a few decades, hundreds of years, it will become the symbol of a new civilization for mankind. From this moment on, we begin to explore the nature of the world!"

"Yes!" Huang Mingshan took the notebook with both hands, his voice was loud and his hands were excited.

How many hundred years?

Since joining this scientific research group, Huang Mingshan's cultivation has risen to the sixth level of the Qi Refining Stage in just over a month. The current Huang Mingshan has no doubt that he will definitely become a master of the Yuan Infant Stage in the future and enjoy a thousand-year lifespan.

Maybe my cultivation qualifications are not good, and my foundation is not good, but ...... His research talent seems to be very good, and the reward from the young master is very rich. Now there are more than a dozen Tsukidans on my body!

Research, continue.

At present, the core of research is not to study the composition of air, combustion processes, etc., but to study the production of ultra-high purity dark iron.

The accident confirmed the oxygen, which can only be said to be an unexpected surprise and a super surprise.

But the road of research is not easy to follow, everyone tries to start with iron ore, and directly separate the dark iron and iron, but in the ore state, the dark iron and iron exist in the form of rust.

In an aura environment, the iron does not rust, but without the aura, the iron will still rust!

Seeing that it was late at night again, Liu Ming suddenly had an idea, and thinned the selected iron powder and bamboo charcoal, stored them separately, and then sealed and heated them together.

This time, a miracle happened.

But the charcoal gradually disappeared, and at the same time, the iron powder gradually faded to a rusty state and appeared a metallic luster. Because the temperature is too high, the reduced iron melts directly, and then injects it into a small smelting furnace (large crucible), and then passes into the aura-rich air to stir and discharge the slag.

It was busy until the second half of the night, when an iron ingot with a total of only 1.7 kilograms appeared.

Compared with other dark irons, there is a faint aura on the surface of this dark iron, like a layer of mist on the surface of the ice, slightly undulating, beautiful and mysterious.

Zhang Hao hadn't learned the identification technique yet, but looking at the strange performance of the Xuantie on the surface, Zhang Hao didn't say a word, took the Xuantie and left.

Father and second uncle were still cultivating, and Zhang Hao directly knocked on Zhou Jue's door.

After entering the door, ignoring Zhou Jue, who was still wearing pajamas, Zhang Hao directly put Xuantie on the table, domineering: "Let's identify it!"

Zhou Juefeng rushed to the table, looking at the Xuantie that could 'breathe freely' aura, his eyes trembling. He had been brewing for a long time, and the fingers that inspired the peculiar identification technique exuded a colorful aura, and after a long time, he said tremblingly:

"The purity is as high as 99.2%! There are no toxic ingredients such as sulfur, realgar, cinnabar, etc. Hiss...... How did you do it?"

Waited for a while, but there was no response.

When he turned his head, Zhang Hao had fallen asleep on the table.

Zhou Jue was stunned and in awe. He didn't bother Zhang Hao anymore, but sat down quietly next to him, took the Xuantie in his hand, and looked at it.

Looking at this, Zhou Jue has made a great discovery!
