"Shut up! Who told you to show off your scientific research results?"

Xu Xingchen showed an ambiguous smile at the corner of his mouth.

Ice Face was silent for a moment, then continued, "I'm sending you there this time to assign you some tasks."

Xu Xingchen became excited.

"What?"

The Ice Face sighed. "Most of the land on your planet is a single-crop land, which is important for studying crop cultivation in the high latitudes of ancient Earth. Go collect some land and send it to me when you're done."

Xu Xingchen asked expectantly, "Boss, are there any rewards? Like a 3 million information point bonus or something like that?"

"I'm giving you the seasoning from the ancient Earth, no more." The voice of Ice Face came.

Xu Xingchen was about to murmur in his heart, but suddenly remembered that this time, Ice Face could hear his thoughts. He immediately stopped thinking and answered in his heart: "Okay."

Finally, I couldn't help but add one more sentence in my heart.

Ice face, still as stingy as ever.

But there is no way around it, a higher-ranking official can crush someone to death.

Xu Xingchen sighed and then began to think about where to get the land.

Land is everywhere. But sampling is tricky. If you want to sample the right, even soil, you can't just dig up any random piece. It's a huge undertaking.

Given the large area here, Xu Xingchen wanted to use a light brain to divide it into one hundred areas, take thirty grams of soil from the center point of each area, and then conduct sample analysis.

Damn Ice Face, he asked people to do the work but didn’t even give them any analytical equipment. I wonder how long it will take to analyze these 100 samples!

I couldn't help but start complaining in my heart.

Xu Xingchen sighed again, rubbed his fingers, and still had to work.

Ancient Earth's seasonings are actually quite scarce on Xu Xingchen's home planet. Perhaps because most of the planet receives insufficient solar heat, they experience winter for most of the year. Similar to the northeastern region of ancient Earth, some areas even experience polar night.

Xu Xingchen looked outside. It was already dark. Before going to bed, the computer had already received the partitioning instructions. He thought he would get the results tomorrow morning.

As for Mundun'er... then let Jun Haoyue take care of it. Mundun'er likes him too, and the two of them can get along well.

Xu Xingchen pouted unconsciously and then fell into a deep sleep.

Jun Haoyue was outside holding Munduner and looking inside through the window.

"Mom is asleep?" Mundun'er blinked.

Jun Haoyue nodded and nuzzled Mendun's nose with his own. "Mom is asleep. Mom just dealt with something very important. Daddy will take you to bed, okay?"

Munduner smiled happily: "Okay! Daddy wants to tell Munduner a story!"

The two walked back to the house, laughing and talking happily. Jun Haoyue brought the prepared firewood, heated up the whole house, put out the fire, and coaxed Mendun'er to sleep.

The next day, Xu Xingchen woke up and opened his computer. Sure enough, he received a regional distribution map. There were 100 areas, and starting from his home, he would collect data piece by piece. It would take an estimated 30 to 40 days.

Phew, looks like I'll be busy in the coming days.

Xu Xingchen went to the fields first, where the most samples were to be collected. After a busy morning, Xu Xingchen had only collected about ten samples, and his back ached from exhaustion.

The samples were obtained, but now the storage of the samples became another problem. However, after thinking for a while, Xu Xingchen's eyes lit up and he quickly came up with an idea.

Back home, Jun Haoyue was playing with Mundun'er. Seeing Xu Xingchen dressed strangely, he asked, "What's wrong? Did he go out to pick something?"

Xu Xingchen nodded, then said to Jun Haoyue, "Can you do me a favor? I need to build another small bamboo house. I can pay you, but you have to wait until spring."

Jun Haoyue put Munduner down and asked Xu Xingchen to follow him outside.

Xu Xingchen followed him out and looked at the bamboo house that suddenly appeared in the yard. He looked at Jun Haoyue in surprise, rushed up and hit Jun Haoyue hard on the shoulder.

"Hey man, how did you know I wanted this? You're the worm in my stomach!"

Xu Xingchen's move could truly be called an assassination. Jun Haoyue, however, remained calm as he said, "I didn't think it was appropriate to leave that chicken outside all the time, so I built a small room for it. It can be considered our storage room."

The small bamboo house was neatly built. The more Xu Xingchen looked at it, the more he liked it. He couldn't wait to walk in.

Before entering the door, Xu Xingchen suddenly turned around, smiled brightly, and said, "Thank you very much!"

Jun Haoyue's pupils dilated slightly, then returned to normal. He raised the corners of his mouth quietly in an invisible place.

"It's okay, it's just a piece of cake."

Xu Xingchen no longer cared about what was happening outside and plunged into the experiment.

The equipment was crude, and all Xu Xingchen could do was use the precipitation method to preliminarily identify various inorganic salts and some organic substances. He could only wait for Ice Face to produce a report using professional equipment.

There were more than a dozen samples, each with a different scent. One sample was particularly fragrant. Xu Xingchen had a hunch that this land must be very fertile.

Xu Xingchen gave priority to the evaluation of the soil.

She first used her own money to buy some inorganic salt reagents, and took five grams of soil and dissolved it in pure water. The pure water was bought by Xu Xingchen on the Interstellar Internet with her own money. Fortunately, she asked for an invoice and could get reimbursed.

First up is calcium hydroxide. Hydroxide can detect most precipitates, and each precipitate has a different color. Although most are white, the degree of whiteness varies. Xu Xingchen has been doing scientific research for so many years that she has already mastered these things.

Stir the soil and pure water evenly, then drop a solution of calcium hydroxide into it. All sorts of precipitates will appear immediately. Because it's clear limewater, we can rule out the possibility that the precipitates are caused by deterioration of the limewater. Instead, they must be the precipitation of inorganic salts in the soil.

The precipitate was air-dried and separated one by one. The inorganic salt content of this soil was unexpectedly rich, and the potassium element, which is crucial for plant growth, was shown to be very pure purple through flame color reaction, just as expected.

Xu Xingchen couldn't help but think of his experimental field.

This would be perfect for growing seeds.

Because when she took samples before, she numbered the samples taken from each area, so if you want to know which area it is, just check the serial number.

You don’t know until you check, and once you check, Xu Xingchen is really stumped.

This piece of soil actually comes from Aunt Wang’s house!

Xu Xingchen was having a headache when he heard a muffled cry outside.

"What's wrong!?" Xu Xingchen quickly put down the instrument and walked outside.
