It was already dark, Wu Qingchen held the wooden bowl, staring blankly at the clay pot on the fire, the steam coming out of the clay pot was still very thin, and it would be a long time before the water boiled.

Wu Qingchen/Luos, who usually looks impatient when waiting for the water to boil, has a faint smile on his face at the moment.

It's the tenth day!

Soon you don't have to go to a place more than ten meters away from the house in order to drink a sip of water that is a little more reassuring!

There is no need to dig pits and filter the soft soil everywhere along the stream! There's no need to grind hard bubbles from anyone to make any "special" barrels! There is no need to look for coarse fiber branches and leaves to mash as turbidity absorbers! Don't wait a whole day for precipitation! There is no need to light a fire pit or a stand, wait for the water to boil, and then spend the same amount of time waiting for it to cool!

It's the tenth day!

Lao Tzu, right away, you can return to Earth!

Lao Tzu, right away, when you want to drink water, you don't need to care about any bird feathers, just unscrew a lid with your hand!

It was getting darker, and Wu Qingchen walked to the stream with a wooden barrel and stood on a small platform that was specially stacked with pebbles.

Wu Qingchen raised his hands from the collar of the outer robe, grabbed the cloth on the shoulder of the outer robe with one hand, and after a while, pulled the inner robe out of it; Immediately afterwards, Wu Qingchen grabbed the large piece of cloth hanging on the edge of the barrel and stuffed the large piece of cloth into the inner robe in the opposite process just now.

After another pause, Wu Qingchen took off his robe, and a little boy who was covered with a large cloth and only a part that was not allowed to be described in a harmonious society appeared next to the stream.

Wu Qingchen/Luos, who is always indignant when he usually makes these actions, has a faint smile on his face at the moment.

It's the tenth day!

Soon you don't have to take a bath and wash clothes, and you can run outside the house in the middle of the night to listen to the wolf howl!

There is no need to put a laundry bath station so as not to slip into the water! You don't have to perform one-handed undressing! You don't have to put on panties in the air! There is no need to continue to perform restricted films with 7 billion viewers! The most important thing is that you don't have to carefully rub the pile of garbage in your hands, and you have to be careful not to crush the garbage!

It's the tenth day!

Lao Tzu, right away, you can return to Earth!

Lao Tzu, right away, you can wash your clothes if you love to do it, and if you don't like to wash your clothes, you can just throw them away and replace them with new ones!

Immediately, when Lao Tzu wanted to take a bath, although there were still at least 7 or 8 people firmly watching, at least they all brought the handles!

Late at night, Wu Qingchen climbed into bed, lay straight for a few seconds, turned around and lay down for a few seconds, then climbed down from the bed again, shook the wheat straw spread on the bed, and rearranged a few places that felt a little uncomfortable.

Wu Qingchen's expression was very indifferent, and he didn't have the irritability of having to complete a few daily steps before going to bed.

It's the tenth day!

Soon you won't have to sleep until you get up to catch fleas and bed bugs!

You don't have to listen to the sound of snoring all over the house! There is no need to listen to the artificial alarm clock of the rooster crow in the middle of the night, and the stars are still hanging in the sky and you can go out to work with a rake!

Lao Tzu, you can go home soon!

Back to Earth!

Return!

Family!

Finish!

Medieval World 0001-02-11, late at night.

Wu Qingchen climbed back into bed, crossed his hands on his chest, and slowly closed his eyes.

After a while, Wu Qingchen's breathing gradually became soothing, and a smile full of joy appeared on his face.

————————

In the center of the large screen on the left: Wu Qingchen smiling and falling asleep, freeze frame.

"Ladies and gentlemen, the terrible supernatural phenomena, the huge impact of values, the harsh living environment, the heavy psychological burden, the 41 consecutive days of heavy physical labor in the medieval world, the series of great changes that the earth has undergone and the full-load training that lasted more than 100 hours, Mr. Wu Qingchen's current mental health state is already very dangerous!"

"...... from here" The red dot of the laser pointer drew a trajectory, encircling Wu Qingchen's smile in the middle of the screen: "Compared with the other two groups of observation records, the clinical manifestations of Mr. Wu Qingchen's depression have been very obvious. ”

The laser pointer turned to the second, that is, the big screen in the middle: in the densely divided small screen, the time and date were xy axes, neatly arranging Wu Qingchen's emotional control groups at different times and days in the past 40 days, such as getting up, brushing teeth, washing face, eating, going out, praying in the morning, laboring, talking, bathing, and falling asleep.

"Look here......" Laser pointer points to the bottom of the screen for a schematic diagram of the parameters: "This set of observations clearly shows two trends......"

"In a single-day longitudinal comparison, from morning to noon to evening, Wu Qingchen's mood changes are manifested as a lower opening parabola......"

The red dot of the laser pointer drew a circle along the trajectory of the parabola: "The closer the time is to noon, the higher the labor intensity, the more depressed and anxious Wu Qingchen's mood tends to be; The closer the time is to the morning, when the labor intensity is expected to gradually increase, the more Wu Qingchen's mood tends to be nervous; The closer the time is to the evening, when the labor intensity can be predicted to gradually decrease, the more Wu Qingchen's mood is inclined to relief......"

"Anxiety, depression, and even nervousness and relief, these emotions will have a strong adverse impact on the psyche, coupled with high-intensity physical labor and huge psychological pressure, the incidence of anxiety and depression, especially the incidence of severe disease!"

"Look here, here, ...... here"

With a few clicks of the laser pointer, Wu Qingchen "carried farm tools to work", "dragged farm tools home", "got up early to go out to collect medicine", "returned home in the middle of the night", and the lonely, tired, lost, and sullen figures were magnified in front of the viewer's eyes one by one.

"It can be seen that even during light physical labor time, most of the emotions shown by Wu Qingchen are biased towards the negative direction......

"Next is the horizontal year-on-year ......"

The laser pointer points to the second parameter diagram below the large screen in the middle: "In each segmented time zone, from the first day of entering the Medieval World until the tenth day of preparing to leave the Medieval World......"

"Look, whether it's getting up, eating, working, or talking...... In the vast majority of individual activities or social activities, Wu Qingchen's mood changes during the same period have been very stable...... Each day is more positive than the previous one, basically in a straight line with an inclination angle of seventeen degrees......"

"This says two things. First, the upward inclination angle shows that Mr. Wu Qingchen was full of disgust, boredom, and even hatred for the harsh environment, complicated labor, and strong pressure of the medieval world...... On the premise of satisfying the minimum survival needs, the first goal is to return to Earth at all times. ”

Second, the consistent tilt angle shows that the achievements of the medieval world, including the acquisition of large amounts of property, the way to be respected, needed, and valued by modern society, which can clearly achieve happiness in modern society, have a positive stimulus to Mr. Wu Qingchen
