Roaming the universe, all thanks to your many dark skills!

Solar Day 24.

Mark moved out a lot of debris in the living cabin, freeing up a considerable amount of space. He then laid plastic sheeting on the floor and sealed it all around with plastic sheeting to keep it warm and moist.

Then he shoveled a lot of soil from outside and brought it into the living cabin and spread it flat on the ground.

When Rosen saw him, he asked if he needed help, but Mark smiled and declined.

Obviously, Mark didn't want to rely on others to plant potatoes. This was a matter of reputation for him as a botanist, and even more so for the dignity of America.

In response, Rosen just shrugged his shoulders and did not insist.

Compared to Mark's relatively slow progress, his work progress is much faster.

So far, the glass greenhouse has been built and divided into eight areas, which are connected to each other but independent of each other, surrounding the container villa like stars surrounding the moon.

This is to facilitate Rosen's farming, and also to maximize the benefits of the Oak Sage.

The soil in the greenhouse had been turned very soft by the poisonous vines, and under Rosen's command, organic fertilizer and various trace elements were mixed in. Then Rosen began to sow seeds.

He grew not potatoes, but sweet potatoes.

The two are essentially different. The former is a Solanaceae plant, while the latter is a Convolvulaceae plant. In addition, their nutritional value and planting methods are also different.

Lawson chose sweet potatoes not simply to compete with Mark through differentiation, but more importantly, they not only grow in large quantities, but are also full of treasures, making them much more cost-effective than growing potatoes.

Of course, the biggest reason is that although he likes to eat shredded potatoes, he doesn’t want to eat potatoes every day.

Perhaps the only thing that sweet potatoes are inferior to potatoes is that they take longer to grow. However, for Rosen, who has no shortage of food, this is not a problem.

In addition to sweet potatoes, Lawson also planted some chicken greens, greens, cabbage, celery, lettuce, peppers, carrots, cucumbers, green peppers, tomatoes... and so on.

Anyway, he bought a lot of seeds and had some spare land, so he naturally planted whatever he wanted.

In addition, he also planted some wheat and corn. He has not considered rice for the time being because it will take a long time to solve the irrigation problem.

Because they were all busy and seldom met each other, let alone communicated, Mark didn't know that Rosen had already completed the sowing, otherwise he would have been extremely envious.

The 31st Earth Day.

Mark began to cut the potatoes into pieces and bury them in the soil, and also applied fertilizer made from the feces of the six of them.

The process is hard, tiring but quite enjoyable.

But when Mark thought that these potato pieces would grow into potato seedlings and then bear fruits in the future, all the hard work would be nothing.

He even thought about inviting Rosen over when the potatoes he grew were harvested, so that he could see that he was worthy of the title of botanist.

It was inevitable that he would always brag about the racial talents of the Chinese people in front of him.

Is it great to be able to farm?

Can it compare to the burning, killing, looting, cheating and swindling that our ancestors of the great America were best at?

With some indescribable emotions in mind, Mark, who had just finished planting the last potato, simply washed his body, put on his space suit and walked to the other side.

He wanted to invite Rosen to come and see the potato field he had opened up.

But before he got close to the container villa, Mark was stunned.

Because a glass greenhouse like a crystal palace stood before him.

Oh my god! How did the Chinese send a glass greenhouse here? Did they come here not for scientific research, but for interstellar colonization?

Mark was deeply shocked. When he looked through the clean and clear glass and saw Rosen squatting in the greenhouse field, doing something unknown, with a field of tender green seedlings under his feet, he was even more shocked.

Who would have thought that after working so hard for so long and finally planting the potatoes, the seedlings on Rosen's side had already emerged.

Is there any justice in this? Is there any science in this?

What kind of plants can grow so fast in an environment like Mars? Mark felt that his knowledge of botany was about to fail.

Rosen suddenly raised his head and saw Mark, then waved and invited him into the greenhouse.

Of course, entering the greenhouse is not just about pushing the door open, but rather passing through a corridor that balances the air pressure and temperature inside and outside, and finally entering the greenhouse.

Mark walked along, looking at the neatly arranged fields and the green leaves sprouting in them. Although he didn't say it, he had to admit in his heart that when it came to farming, no race in the world could compare to the Chinese.

"Mark, look, the vegetables I planted earlier are growing pretty well, aren't they?" Rosen said with a smile, "In a few days, when they grow taller, I'll pick some to make dumplings. You must come and taste them then."

"Okay." Mark nodded, and then asked, "How did you solve the irrigation problem?"

"I know a little magic. I can just wave my hand and water will appear naturally." Rosen told the truth.

But Mark thought he was joking, and thought that maybe this involved the Chinese's secret technology, so he was not willing to reveal it and could only make up nonsense to cover it up.

Mark stopped asking questions and said, "I'm also trying to grow potatoes, and I've figured out how to solve the irrigation problem. I'll let you know if I have any results later."

"Okay." Rosen nodded with a smile and said, "Be careful."

"understood."

"Walk slowly, don't send."

Solar Day 35.

Rosen fulfilled his previous promise and picked a batch of tender green Chinese cabbage (note), made dumplings with pork as stuffing, and invited Mark to come and share.

At the same time, he also fried a few home-cooked dishes and opened a bottle of Lao Baigan.

Mark was a little hesitant when he came, but he slowly relaxed after he started eating, and kept shouting, "It smells so good! It's so delicious!"

Especially after drinking, he was in high spirits, talking a lot and incessantly, as if he wanted to sing himself to Rosen.

"You know, the biggest problem with growing potatoes is water. I have 126 square meters of soil. Each cubic meter of soil requires 48 liters of water for planting, so I have to create more water."

Mark said this, looked at Rosen and said, "Fortunately, I have thought of a way. I will show you tomorrow. How about it? Do you want to come and witness this historic moment?"

"Okay." Rosen recalled the scene in the plot where the fire exploded and said with a smile, "I will definitely go. Maybe I can save your life."

"You must be joking. It's not certain who will save whom." Mark boasted to Rosen before saying goodbye and leaving.

The next day.

Mark drove Rosen to the bottom of the aircraft, and while pushing a tube connected to a gas tank onto the nozzle, he said, "Rosen, let me ask you a question. What will be produced by hydrogen and oxygen?"

Note: If you want to know about the relationship between Pakchoy and Chinese cabbage, you can research it yourself. For me, I will assume that Pakchoy is the young version of Chinese cabbage.
