In front of Chen Mo, it was an instrument the size of a basin.

The instrument has a peculiar shape, with a hollow inner ring in the middle, filled with a red transparent liquid, surrounded by thumb-sized tubes, a fan in the center of the instrument, and a large tube below the fan, which leads to the inside of the ring tube.

This device is the oxygen generator.

Chen Mo is a machine used to accelerate the conversion of Martian carbon dioxide into oxygen and accelerate the transformation of the Martian atmosphere.

The liquid inside the tube is a catalyst that captures carbon dioxide and sulfur dioxide in the air, makes the molecular structure more active, and then electrochemical to break down carbon dioxide into carbon elements and oxygen.

"Run, try."

"Okay."

The ink girl pressed the remote control, and saw that the fan in the center of the oxygen generator began to rotate.

Chen Mo deliberately used dry ice to put it near the fan, and he could clearly see the adsorption force of the fan, which was absorbing the surrounding air into the ring tube, and the liquid catalyst inside was also bubbling wildly.

If you look closely, you can see that the bubbles gradually become smaller during the ascent, and in the liquid catalyst, you can also see a little bubble, like a small bubble in Coke, attached to the inner wall of the tube.

Those little bubbles are the oxygen that breaks down.

After a long time, Chen Mo could already see the little black solids precipitated in the liquid, which were the diluted toner element.

"This small oxygen generator works non-stop, it can produce one kilogram of oxygen per hour, and at the same time, it only needs to separate the solids inside, and the catalyst can be reused. The solids are mainly carbon and sulfur elements, which can be used as materials for the manufacture of diamonds, graphene and carbon nanotubes after separation and washing processing. Mo Nu said.

"On Mars, we started to build large oxygen generators and some mobile oxygen concentrators." Chen Mo said.

"How many are needed?" Mo Nu asked.

"The sooner the oxygen on Mars can reach the standard of biological survival, the better, there are no specific units." Chen Mo said.

Now the transformation of the Martian atmosphere is the problem he is facing.

It takes a long time for the atmosphere of Mars to meet the standards of human habitation, close to the plants in Mars, so Chen Mo has to use scientific and technological means to directly transform the atmosphere.

The most important thing in the manufacture of oxygen generators is those catalysts, which are prepared by the catalyst, and the machine manufacturing is very simple.

Under Chen Mo's order, the chemical plant in the city of Mars began to prepare the required catalysts.

……

Wushuang held a lollipop in his mouth, took Chen Mo's hand, and entered the elevator of the hotel, next to her were Xiao Yu and Mo Nu.

"Dad, grandparents are not good at coming this time."

"You know again?" Chen Mo asked with a smile.

"Of course I know, it's not the first time my grandparents have come here." Wushuang said to himself: "If you and your mother don't give me a few more brothers and sisters, my grandparents will be in a hurry." ”

"Hey, little girl, eat your lollipop."

Every once in a while, Xiao Yu would take Wushuang back to accompany her grandparents to dinner, or her parents would come to Binhai City from their hometown to find them.

Every time they met, they would use various hints to let him and Xiao Yu have a second child, and every time Chen Mo pretended not to understand, and then fooled him.

Entering the box, Chen's father and Chen's mother were already sitting on the table, Aunt Zhen and her brother-in-law were also there, and Zhang Xinxin was also present.

"Grandpa, grandma." Wushuang saw the two old men and ran over in small steps.

"Eh, Wushuang came here to sit."

When Shao Xuemei and Chen Shanhe saw Wushuang, they immediately smiled, pulled out the chair in the middle, and let Wushuang sit on it.

"Mom and Dad, Aunt Jane, Uncle-in-law."

Chen Mo and Xiao Yu asked briefly and found a place to sit down.

The whole family arrived.

"Mom, did you order?" Xiao Yu asked.

"It's ordered, you guys come here, and you can serve the food." Wushuang and Chen Shanhe were chatting, and Shao Xuemei asked the waiter to start serving: "Xiaoyu, I have ordered some dishes that are good for your health, today you eat more, the most important thing is to take care of your body." ”

Xiao Yu took the menu and said with a smile: "Got it, thank you, Mom." ”

"Eh, don't be polite to your mother." Seeing the waiter serving the food, Chen's mother hurriedly introduced: "Xiaoyu, come and try the black phoenix motherwort soup and white fungus lotus seed soup, which is very good for your health." Eat whichever you like. ”

"What is Black Phoenix Motherwort Soup?" Chen Mo asked curiously.

"Black chicken, motherwort." Zhang Xinxin reminded Chen Mo in a low voice.

“……”

"There is also this lotus cinnamon cake dim sum, don't eat it for the time being, and eat it after eating. There is also this dragon and phoenix Chengxiang, two dragons playing with pearls, magpie Dengmei, and five sons Dengke......"

"Poof!" Zhang Xinxin drank the soup and couldn't help laughing, but immediately restrained her smile and pretended to pick up the vegetables.

"Mom, order so much, are you done eating?" Chen Mo didn't dare to laugh if he wanted to.

"If you can't finish eating, pack it, it's hard to come out and eat a meal, usually at home, Xiaoyu cooks for you, isn't it good to let Xiaoyu eat a little more now? Also, there are so many people in the family, where are these dishes? Chen Shanhe said solemnly.

"Well, not much, it's good, it's good." Chen Mo looked at Xiao Yu with an innocent face and gave her a helpless look.

"I want the last dish, Baizi Ruyi, this name is the most auspicious."

“……”

This time, even Aunt Zhen and her uncle-in-law had smiles on their faces.

"What are you doing in a daze, give Xiaoyu vegetables, how do you become a husband? Let Xiaoyu eat more, hungry daughter-in-law? ”

"Okay."

Chen Mo couldn't help laughing, and gave Xiao Yu a dish, and the delicate presentation was directly destroyed by Chen Mo's chopsticks.

"Xiaoyu, is it delicious?" Mother Chen asked softly.

"It's delicious, thank you Mom." Xiao Yu said with a smile.

"Then eat more, the body is the most important."

Mother Chen smiled, and thought for a while before speaking.

"Xiao Mo, Wushuang is so old, sometimes Wushuang tells me that she has no playmates alone and wants a younger brother and sister? Isn't it, Mushuang. ”

"Yes, I want younger siblings."

"Ugh!!" Chen Mo was slightly stunned.

In the past, it was all to imply and explicitly, but this time it is direct.

"There's no hurry."

"Not in a hurry? How much longer? Wushuang is so big. ”

Hearing Chen Mo say that he was not in a hurry, Chen's mother was suddenly unhappy.

"Your dad and I haven't rushed you before. It's just that my parents are old and want to have two more grandchildren to accompany them, and they are happy. Xiaoyu, can you fulfill your parents' wishes? If you don't want to take the child, Mom can help you bring it. ”

In the end, Chen's mother looked lost.

"Mom, don't worry, Brother Mo and I are preparing." Xiao Yu hurriedly comforted.

"That's good, it's good to prepare, Mom is not in a hurry, Mom also knows that if you are in a hurry, it will not happen overnight." Chen's mother was immediately happy, and she sandwiched a big abalone for Xiaoyu.

Zhang Xinxin next to her was just eating with her head buried in her face, smiling all over her face.

Chen Mo and Xiaoyu suddenly had a feeling of being deceived.

After eating, Chen's mother took Xiaoyu and Mo Nu to accompany her and Aunt Zhen to go shopping, and Chen Mo was directly disgusted. Looking at the backs of them leaving, Chen Mo was a little depressed, but when he saw his mother happy, he also smiled.

……

That night, Chen Mo sat on the holographic platform in the study, paying attention to the progress of the Martian chemical factory.

The problem of Mars' atmospheric modification is the top priority of his current work, and there is no other major science and technology that he wants to study in particular, so Chen Mo is now wholeheartedly engaged in the Mars project.

Xiao Yu and Mo Nu entered the study, Xiao Yu wore a translucent little nightdress, walked to Chen Mo's side, and sat on his lap.

"Did you have fun with your mom today?"

"Well, Mom gave me and Mo Nu a pair of jade bracelets." Xiao Yu raised his hand and put the jade bracelet on his wrist in front of Chen Mo's eyes.

"It's pretty." Chen Mo said.

"This jade bracelet carries a mission, a heavy mission, the Moshu can't have children, only I can complete it." Xiaoyu touched his belly, "I haven't done anything, why can't I get pregnant?" ”

Over the years, she also wanted a second child, but her stomach has not moved, and she usually does not do anything.

"Maybe I'm evolving too fast and I'm reproductively isolated." Chen Mo said jokingly.

"Then may I ask the officer, what species are you now?"

"A very powerful new human."

"New new humans? Does the official want to create a race? The little woman is willing to do her part. Xiao Yu said jokingly in Chen Mo's ear, and also blew the aroma mischievously.

"Poof...... Ahem......"

Chen Mo was choked by his own saliva, and his face turned red.

Xiao Yu was already trembling with laughter, and Mo Nu laughed and gently stroked Chen Mo's back.

"I won't tease you, concentrate on your work, and go back to your room to rest when you're done." Xiao Yulai was in Chen Mo's arms, unwilling to come down, and quietly accompanied Chen Mo to look at what he was studying: "This instrument is the oxygen generator you said?" ”

Chen Mo nodded.

"Oxygen generator technology is not difficult and is now being made on Mars. When it is manufactured, the speed of transformation of the Martian atmosphere will be greatly improved, I just want to see the progress, but there are more important things to do next, it doesn't matter if you look at the progress or not. ”

"What's more important?"

"What do you say?"
