Although the manpower threshing machine is labor-saving, the continuous and uninterrupted pedaling of the drive plate of the threshing machine is still a hard work, which is very physically laborious for a long time, and the muscle load on the lower body thighs and calves is not small.

Su Zu came to thresh rice to prepare to do this job, he was not skilled in cutting rice with a sickle, and it was easy to hurt himself if he was not careful. But at least pedaling on the threshing machine and threshing the rice on top should still be competent. What's more, in this process, the training of the leg muscles can also continue to increase the potential.

Su Yuanhua and Ye Qingmei have already gone down to the field to start cutting rice, and the paddy fields of the autumn harvest have long been drained and dried, and people will not fall into the mud when they step on them.

Su Zu and his parents cut a lot of rice ears, and the dew was no longer so wet and heavy, so they moved the cut rice ears to the threshing machine and began threshing.

One foot supported the ground, and the other foot stepped the drive plate of the threshing machine, and the drum grunted and turned. Holding the ears of rice on top of the drum, the sound of rattling sounded one after another, and the threshing began.

As Su Zu began to work on the threshing machine, under his field of vision, the data of the potential value of "+0.1% potential" continued to emerge.

"Sure enough, the increase in the potential value of labor exercise is also effective."

It didn't take long for Su Zu to change his legs, feeling heavy in his steps, and his body began to get tired. However, the value of the potential column is also jumping, and has jumped to 64.2%. The accumulation of potential seems to be improved as long as the body is exercising at a high intensity.

"However, can you block this reminder, I keep jumping out, and it feels like I have floaters."

Su Zu complained in his heart, and then was surprised to find that the attribute box under the field of vision had disappeared, and the potential value increase reminders one by one no longer appeared.

"This is good, quite humane."

A smile appeared on Su Zu's face, and he gradually devoted himself to the work of rice threshing.

The boring, repetitive and extremely physically energy-consuming work can easily make people physically and mentally tired, but Su Zu has been gritting his teeth and persevering. Only by engaging in this kind of high-intensity physical labor can you appreciate what hard labor is.

"If it's still the same self who doesn't do more, I'm afraid I won't be able to do it for a while."

Su Zu remembered that although he could endure some hardships, he was always grateful for doing farm work in the fields, and later went to high school, college, talked about girlfriends, and rarely mentioned his background to others.

The kind of sensitivity that was born because of low self-esteem was not until he achieved something in his career later and was able to gain a foothold in a big city, and he was gradually able to formalize his origin.

"Su Zu, are you tired, let your dad come when you're tired." Ye Qingmei watched Su Zu's forehead start to sweat, her movements seemed to slow down a little, and she couldn't help but speak.

"I'm not tired, Mom, I'm still quite energetic." Su Zu wiped his sweat and smiled and showed a mouthful of white teeth.

"Don't be reckless, it's not that you can't do it, just rest when you're tired."

"Well, I know, I'll do it again, and then I'll change my dad if it doesn't work."

The sound of threshing machines spinning resounded through the fields, and large swaths of golden rice were cut down and threshed. Su Zu summoned the system for a while, and then hid it for a while. Although the body is tired, but watching a little bit of potential value is increasing, and there are more and more threshing and bagging rice, I actually find a little bit of the feeling of playing online games to upgrade and fight monsters.

At the end of the day, Su Zu and Su Yuanhua, father and son, took shifts, and their work efficiency doubled compared to before.

Towards evening, the family of three had already bagged the beaten rice and put it neatly on the pallet truck, four more bags than usual.

After returning home, Su Zu took a bath at the urging of Ye Qingmei, and after a hasty dinner, he went directly back to the room to lie down and rest, after a whole day of work, his legs were already heavy like lead, his back hurt, and he didn't even want to move his little thumb when he lay on the bed.

His physical fitness, strength and endurance are not high, and the young man in his teens will work hard for a day, even if he has the experience of later generations, he will distribute his physical strength more scientifically, and he is not lightly tired.

Spread out his limbs and lay lazily on the bed, Su Zu only had time at this time to check the system carefully. As soon as the thought moved, a translucent property panel appeared in front of him again.

Name: Su Zu

Age: 15

Occupation: Student

Physical fitness: 8

Agility Qualities: 14

Strength qualities: 8

Reaction Qualities: 13

Endurance qualities: 9

Pliable qualities: 13

Potential: 103.2%

"More than 100% potential?!"

Su Zu felt a wave of joy in his heart, and noticed that the gray "+" behind the various qualities was lit up again at this time, and he could add points again.

At the beginning of this day, I noticed the increase in potential, but after I activated the shield and hide function, I didn't pay attention to it again.

After eight or nine hours of work a day, Su Zu actually realized that the three qualities of physical fitness, strength and endurance of this body were too poor, especially compared with an adult man like Su Yuanhua, it was far behind.

Su Zu thought about it again and again, and did not add this attribute point to physical fitness or strength, but once again focused on agility quality. After adding points, his agility quality has reached 15 points.

Agility is directly related to the cadence of running, cadence determines speed, and his current speed is far from enough. With his addition, the potential column has also changed from 103.2% to 3.2%.

After all, Su Zu also understood that he was only a sixteen-year-old boy now, and if he was counted as one year old, he was still a few months away from fifteen years old. Physical strength, endurance, reasonable diet and exercise, as the body grows and develops with age, will slowly reach the level of an adult man.

Moreover, the balanced development of various attributes is difficult to produce results in the short term, after all, the growth of each point of potential value requires a lot of exercise by itself. It is better to further amplify the advantages, so that he can choose the path of a sports athlete, and it can be more convincing.

He has a system in hand, he has a good speed, and he wants to engage in the most popular sprint events, not to practice weightlifting shot put marathon.

The next Sunday, Su Zu woke up to find that his body was a little sore, and his exhaustion was swept away. Young people have a strong recovery ability, and they can live again after a basic solid sleep.

Su Zu still wanted to follow the field to harvest rice, but Su Yuanhua and Ye Qingmei did not agree again, and they all saw the hard work of the previous day. Parents are always willing to work harder and suffer less for their children.

Moreover, with Su Zu's help yesterday, the harvest was almost complete. Su Zu has to go back to Yangxin Middle School in the afternoon, so it is better to rest at home and review his homework.

Su Zu couldn't resist his parents, so he had to obediently stay at home and do some push-ups and other exercises to accumulate potential value.

The various books and test papers in the schoolbag have not been flipped through, and now he is afraid that he will not be able to understand everything except for a few or two subjects.

At noon, Su Yuanhua and Ye Qingmei came back and prepared for Su Zu for the next week's living expenses, Su Zu packed up his clothes and rushed back to Yangxin Middle School.
