The teaching time this time was a little longer than last time. After the broadcast stopped, everyone didn't speak for a while, and they were thinking about the meaning of its words.

The one with the heaviest expression among the twelve people was Xue Xin. Just now, he used the knowledge he learned in class to issue a long discussion, speculating on the possible teaching content of the "power class", but he did not expect that the original place was completely different from the book, or even very different. This is a magic academy - he directly skipped the boiler's steam burning process and turned into a magic crystal.

After thinking about it, they began to discuss. The course requirements this time are actually very simple. But first change the time. After a class-rest cycle, the table in this place took a whole circle and converted it into a more common time unit. It can be considered that the clock circle is 24 hours, their class length is 12 hours, and the "hour hand walks 15 degrees" is one hour.

Every hour, the demand for conveyor belts will change once. Every two hours, the furnace will produce a batch of "refined substances" - that is, the large pile of red and black crystals placed at the mouth of the furnace.

The first hour's demand is "red hot crystals". They have to pick all the red crystals out of the pile of crystals within an hour and put them on the conveyor belt to provide energy to the fortress. Moreover, only those that generate heat in the red crystals are qualified. What does not generate heat is waste, which cannot provide energy, and is harmful and must not be put into the conveyor belt.

In the second hour, all the trembling black crystals were picked out and sent to the conveyor belt. The pile of refined objects at the entrance of the furnace was completely removed. But at this time, a new batch of refined objects were sent out again. In this way, the complete six batches of refined objects were completed, even if today's classroom learning task was completed.

Yu Feichen picked up two crystal stones and put them in his hand. As the radio said, the red ones were warm and the black ones would tremble. But the stone was not slippery, so he could only pick it up by scooping three fingers.

Lilia breathed a sigh of relief and said, "It sounds much simpler than yesterday."

"Not seen," Vincent said, "they are too many."

The furnace itself is already extremely huge, and the pile of refined objects is nearly three people tall. Each crystal is only the size of a thumb, and the number is unimaginable.

Yu Feichen also looked at the pile of crystals, his eyes slightly deeper. To be honest, today's task is more difficult than yesterday. It is not difficult to distinguish between red and black, whether it is hot or not, or whether it is tremor, but humans are not machines and have inertia that are difficult to control.

At this time, the female painter Ke An also spoke: "Have you heard of that fable about picking up stones?"

“Which?”

"I remembered it in a book when I was a child, so I can't remember it very clearly, so I can only repeat it according to my memory." Ke An said: "It is said that among the countless pebbles on the beach, a priceless pebbles would heat up. So a man picked up stones day and night on the beach. Every time he picked up a piece of stone, he threw it into the sea. After a long time, one day, he suddenly burst into tears."

Lilia: "Why do you cry?"

"Because the stone he just picked up was warm, but he was used to throwing it out. It was not until the stone disappeared into the sea that he felt the remaining warmth in his palm. Unfortunately, it was too late."

After she told the story, everyone looked at the crystal stone pile with lingering fear. Xue Xin said: "Muscle memory is terrible."

Yu Feichen glanced at the time and said, "Get ready."

Then he looked at Anfir beside him, and he would faint for a while every time he rode a roller coaster. Anfir was grabbing his wrist and maintaining balance, saying, "I'm fine."

I heard Chen Tong say, "I really can't guarantee that I can pick the right one. Why don't we choose one by one and the other check it?"

"There is not enough time." Yu Feichen rejected the proposal.

If the twelve people work at full speed, it is still possible to pick up so many crystals in two hours. If half of them are drawn to check, the task will not be completed at all. However, there is indeed a way to pre-order and reduce some of the time.

"We need to draw out one person to sort the red and black colors first. We try to identify the scraps as much as possible in the first sorting, but do not force it, and move quickly. The sorter will send the solid-colored crystals to other people. The other eleven people remained in place and picked qualified crystals and put them into the assembly line." He said.

Vincent said: "Yes, this can save overall time. The red and black color identification is much simpler than the scrap identification. In order to prevent errors in the scrap identification on the assembly line, it is best to let the careless people of us come out for the first simple sorting."

Ke An added: "The crystals are quite heavy together. This person should send solid-color crystals to the next to each assembly line. It is best to have more strength."

Fast movements, carelessness, and strong strength.

These conditions were added up, and everyone suddenly looked at the sprinter Chen Tong in unison.

"What do you mean? Am I like a careless person?" Chen Tong was very confused. As he spoke, his voice became a little weaker, "Choose... pick... pick. I am really strong."

Time is limited, and work starts after the division of labor is completed. In the first hour, they have to finish all the "red hot crystals". Chen Tong's first sorting also takes time. Others packed a bucket of variegated crystals in metal buckets and divided them first.

Yu Feichen's assembly line was next to Anfier. After he confirmed that Anfier would not fall down while picking it, he also started working. Twenty red heating crystals were quickly picked out and thrown on the assembly line. The assembly line quickly took them away and disappeared into the teleportation track below the ground. He picked twenty of them, and they were all qualified products, and the scrap rate was not high.

Chen Tong's movements were also very fast, and in just ten minutes, everyone carried a bucket of red solid crystals. Everyone's attention was highly focused on the stones in their hands. This was a tiring task, and even Chen Tong spontaneously silenced. The classroom was silent, with only the collision of crystals, the buzzing sound of the magic furnace, and the friction of the conveyor belt.

The material of the conveyor belt is extremely special. It is a dark and rough soft metal, not the materials that Yu Feichen had seen before, but like sandpaper that was tens of thousands of times stronger. After moving it for more than ten times, Chen Tong stared at the conveyor belt in a daze while he was slowing down. Suddenly, his hand was a bit cheap and touched the conveyor belt with his little finger like lightning. As a result, he screamed, and his little finger had already cut a soybean-sized thorn, dripping blood.

Xue Xin shook his head helplessly at his elder brother's curiosity: "The surface of this magical stone is too smooth, and it's a bit difficult for us to hold it. In order to drive them, the surface of the conveyor belt must be made of materials with high friction... and with such a fast speed and strong lethality. Brother Chen, don't touch it again."

Chen Tong grinned and learned a lesson, and even said that he would not move around again.

After that, there was a long silence and heat. The magic furnace emitted heat like a heart, but they all remembered the school rules that "no disheveled clothes" and dared to loosen the tight cuffs a little. In just half an hour, Lilia's short curly hair was already wet on the forehead.

Yu Feichen is fine, his mood has always been very stable, and such people are generally not afraid of heat.

But he always felt something pressing on his heart, like an ominous layer of darkness.

Did he ignore something? But he looked around and everyone had an orderly work, so there was no problem. On the contrary, the more he wanted to explore, the less he could find the source of that kind of prediction, and he felt that something was wrong.

At the same time, he didn't stop picking up his hand. He took out one from the bucket, confirmed the temperature, and put it on the conveyor belt. The crystal was quickly transported away by the conveyor belt, and then the next one, the next one...

The mechanical movements are repeated one after another, making people feel that they have already had a robotic arm that can only work simply on the assembly line. There are hundreds of them, and they have not encountered a single scrap product. The pass rate of the refining product is very high.

But the higher the pass rate, the stronger the inertia formed by mechanical actions, and once an error occurs—

He stared at his two-point and one-line movement, his eyes gradually sinking, and the gloom in his heart gradually magnified.

Until a scream suddenly came from the other side of the eight legs!

Yu Feichen suddenly looked over there.

"I threw it wrong!" Eight legs threw stones in half, their face pale.

The dangerous precept suddenly magnified and completely concreted. Yu Feichen blurted out: "Don't move!"

Eight legs heard it, but the movement had already been done before the brain. Before the wrong stone had been spread far, he suddenly reached out to reach it, and the five fingers of his left hand were buckled down, gathering the slightly cool red stone.

But his hand was pulled forward by a conveyor belt with extremely heavy friction.

A rapid shout came out from the mouth of eight legs, and the conveyor belt quickly rolled forward. His whole body was carried by his left hand, and half rolled and half rolled onto the conveyor belt in a twisted posture.

Yu Feichen rushed here first, and Chen Tong ran over immediately.

"Don't move!" Yu Feichen said again. But Eight Legs were no longer caring about anything. In order to escape from the conveyor belt, he twisted wildly. He was extremely strong and the conveyor belt was too fast. In the blink of an eye, it had already rolled to the end. Fortunately, the two arrived at the same time and grabbed Eight Leg's arms and shoulders from both sides.

The next second Vincent also rushed over, and the three of them controlled him together and lifted his whole body up.

The non-shaped scream in the mouth of the eight legs suddenly rose. After the body did not move in synchronously with the conveyor belt, the thick metal surface quickly rubbed his legs that were still on the conveyor belt. The clothes were instantly worn out, and the next moment, the flesh and blood were scraped off, revealing white bones.

The extreme pain stimulated him to arch his back, but it made his body, which was originally lifted, touch the surface of the conveyor belt, and instantly increased the friction.

In the next second, nothing was left on the conveyor belt.

The broken body was pushed and wrapped by a fast-moving conveyor belt and disappeared into the underground teleportation port. Only Chen Tong stared at an arm in his hand. The wound on his little finger was still bleeding. Almost, he would end up like this.

Another vivid life disappeared into a mechanical structure that could not be wrong. His name was Charastras. Because it was too difficult to read, everyone called him "Mr. Eight-Legged".

Xue Xin buried her face in pain and said hissing: "I said it, don't touch the conveyor belt..."

But it's too late to say anything now.

Yu Feichen turned around silently and looked at Anfier who was looking at this side of Yaoyao. Anfier had already woken up from his dizziness, lowered his eyes, and suddenly pointed to Ke An on his right.

At this moment, Yu Feichen fully realized what that ominous predation was. He realized... what a big mistake they made.

He said hoarsely: "Don't put the stones on the conveyor belt in the future. Put them in the bucket first, and then pour them into the conveyor belt."

In this way, if something goes wrong, there is another chance to remedy it.

Adding such a simple link can avoid the tragedy of eight legs, but before the accident happened, no one remembered it.

Before the beginning, Ke An said a familiar fable out of kindness to warn everyone, and naturally everyone threw one and threw it away like in the story - and eventually fell into the same mistake in the fable.

What is more terrifying than the inertia of the body is the inertia of the heart. After all, people are not mechanical.
