Chapter 721

In front of Chen Mo is a basin size instrument.

The instrument has a unique shape, the middle ring is hollow inside, filled with a kind of red transparent liquid, surrounded by thumb sized tubes, the center of the instrument is a fan, and under the fan is a large tube, and the inside of the tube leads to the inside of the ring tube.

This instrument is an oxygen generator.

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

The liquid in the tube is a kind of catalyst. The catalyst can capture carbon dioxide and sulfur dioxide in the air, make the molecular structure more active, and then electrify and separate carbon dioxide into carbon and oxygen.

"Try it."

"Good."

When Mo Nu pressed the remote control, the fan in the center of the oxygen generator began to rotate.

Chen Mo purposely put dry ice near the fan, and can clearly see the adsorption force of the fan. He is absorbing the surrounding air into the annular tube, and the liquid catalyst inside is also frantically bubbling.

If you look carefully, you can see that the bubbles gradually become smaller in the process of rising. In the liquid catalyst, you can also see a few bubbles, just like the small bubbles in coke, attached to the inner wall of the tube.

Those little bubbles are the dissolved oxygen.

After a long time, Chen Mo has been able to see the little black solid precipitated in the liquid, that is, the diluted carbon powder.

"This small oxygen generator works continuously. It can produce one kilogram of oxygen per hour. At the same time, it only needs to separate the solid in it, and the catalyst can be reused. The solid is mainly composed of carbon and sulfur, which can be used as materials for diamond, graphene and carbon nanotubes after separation and cleaning. " Said Mo nu.

"Large scale oxygen generators and some mobile oxygen generators have been built on Mars." Chen Mo said.

"How many do you need?" Asked Mo nu.

"The faster Mars's oxygen reaches the standard of biological survival, the better. There are not many." Chen Mo said.

Now the transformation of Mars atmosphere is the problem he faces.

It will take a long time for the atmosphere of Mars to reach the standard 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 generator is the catalyst. The catalyst is prepared by mixing. The machine manufacture is very simple.

Under Chen's silent order, the chemical plant far away in Mars city started to prepare the catalyst needed.

……

Unparalleled with lollipops, holding Chen Mo's hand, into the hotel elevator, beside her are Xiaoyu and Mo nu.

"Dad, Grandpa and grandma 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 that grandparents have come here." Matchless self-care said: "you and my mother do not give me a few more brothers and sisters, grandparents can be worried."

"Hey, little girl, eat your lollipop."

Every once in a while, Xiaoyu will go back to accompany her grandparents for dinner, or her parents will come to Binhai city from their hometown to find them.

Every time we meet, we will use all kinds of hints to make him and Xiaoyu have a second child. Every time Chen Mo pretends that he can't understand them, and then makes a fool of them.

When entering the box, Chen's father and mother are already sitting on the table, Zhen's aunt and uncle are also there, and Zhang Xinxin is also there. When seeing Chen Mo and Xiaoyu coming, they also smile but don't talk. Obviously, they just heard something that they shouldn't have listened to.

"Grandpa, grandma." Matchless saw two old people, trot past.

"Ah, no one can come here."

Shao Xuemei and Chen Shanhe see matchless, immediately smile, open the middle chair, let matchless sit up.

"My parents, my aunt, my uncle."

Chen Mo and Xiaoyu simply asked, and they sat down.

The whole family is here.

"Mom, have you ordered?" Xiaoyu asked.

"Order. Come here and serve." Matchless and Chen Shanhe are chatting. Shao Xuemei asks the waiter to start serving: "Xiaoyu, I ordered some dishes that are good for your health. Today, it's most important for you to eat more and take good care of your health."

Xiaoyu took over the menu and said with a smile, "I see. Thank you mom."

"Well, you're welcome to mom." Seeing the waiter serving, Chen's mother hurriedly introduced: "Xiaoyu, come to taste the black phoenix motherwort soup and the white fungus lotus seed soup. It's very good for your health. Eat whatever you like. "

"What is Heifeng mother grass soup?" Chen Mo asked curiously.

"Black chicken, Leonurus." Zhang Xinxin whispers to Chen mo.

“……”

"There is also the dessert of the lotus seed cake. Don't eat it for the time being. Wait until you have finished eating. And the dragon and the Phoenix, the dragon and the Pearl, the magpie and the plum, and the five sons and the family... "

"Pooh!" Zhang Xinxin drinks soup, can't help laughing, but immediately converges smile, pretends to take vegetables.

"Mom, order so much. Are you finished?" Chen Mo didn't dare to laugh.

"It's hard to come out and have a meal if you can't finish. Usually at home, Xiaoyu cooks for you. Isn't it good to let Xiaoyu eat more now? What's more, there are so many people in the family. Where are these dishes Chen Shanhe said solemnly."Well, not much, very good." Chen Mo looks at Xiaoyu innocently and gives her a helpless look.

"And the last dish, baiziruyi, is the most auspicious name."

“……”

This time, even aunt Zhen and her uncle were smiling.

"What are you doing? How can you be a husband? Let Xiaoyu eat more and starve his wife? "

"OK."

Chen Mo grins, sandwiches vegetables for the small fish, and sets the plate delicately, which is directly destroyed by Chen Mo's chopsticks.

"Xiaoyu, is it delicious?" Chen asked in a soft voice.

"It's delicious, thank you mom." Xiaoyu laughs.

"Then eat more. The body is the most important thing."

Mother Chen smiled and thought for a moment before opening her mouth.

"Xiaomo, matchless is so big. Sometimes matchless tells me that she wants a younger brother and sister without a playmate? Isn't it, unparalleled. "

"Yes, I want my brother and sister."

"Er!" Chen Mo is slightly shocked.

In the past, I have come to express myself by implication, but this time I have come directly.

"Don't worry."

"Not in a hurry? how much longer will it be? It's so big. "

When Chen Mo said she was not in a hurry, Chen's mother was not happy.

"Your father and I haven't urged you before. It's just that my parents are old and want to have two more grandchildren with me. I'm happy. Xiaoyu, can you satisfy your parents' wishes? If you don't want to take your children, mom can help you. "

When it comes to the end, Chen's mother looks lost.

"Mom, don't worry. Mogo and I are preparing." Xiaoyu hurried to comfort him.

"That's good. Just prepare. Mom is not in a hurry. Mom knows that it's not a matter of one day and one night." Chen's mother was very happy. She caught a big abalone for Xiaoyu.

Next to her, Zhang Xinxin just buried her head in a meal and smiled.

Chen Mo and Xiaoyu suddenly feel cheated.

After dinner, Chen Mu pulls Xiaoyu and Mo NV to accompany her and aunt Zhen to go shopping. Chen Mo is directly rejected. Looking at the back of their departure, 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 his study and watched the progress of the Martian chemical plant.

The atmospheric reconstruction of Mars is the top priority of his current work. There is no other major technology to study at present, so Chen Mo is now fully committed to the Mars project.

Xiaoyu and Mo NV enter the study. Wearing a translucent sleepdress, Xiaoyu comes to Chen Mo and sits on his lap.

"Have fun with mom today?"

"Well, mom gave me a pair of jade bracelets with Mo nu." Xiaoyu raises his hand and puts the jade bracelet of his wrist in front of Chen mo.

"It's pretty." Chen Mo said.

"This jade bracelet is carrying a mission. It's a heavy mission. Girls can't have children, but I can do it." Xiaoyu felt his stomach. "I didn't do anything about it. Why can't I have it?"

Over the years, she also wants to have a second child, but her stomach hasn't moved and she doesn't usually do anything about it.

"It's possible that I evolved so fast that I was segregated." Chen Mo joked.

"What kind of species are you now, officer?"

"A powerful new human being."

"New human? Does the official want to create a race? The little girl is willing to do something Xiaoyu joked in Chen Mo's ear, and mischievously blew the fragrance.

"Poof Cough... "

Chen Mo was choked by his saliva and turned red.

Xiaoyu has already laughed, and Mo Nu smiles and caresses Chen Mo's back.

"Don't tease you. Concentrate on your work and go back to your room to have a rest." Xiaoyu lies in Chen Mo's arms, unwilling to come down, and quietly accompanies Chen Mo to see what he has studied: "this instrument is what you call the oxygen generator?"

Chen Mo nods.

"The oxygen generator technology is not difficult. It is now being built on Mars. When it's created, the speed of Mars atmosphere transformation will be greatly improved. I'm just looking at the progress, but there are more important things to do next. It doesn't matter whether we look at the progress or not. "

"What matters more?"

"What do you say?"
