At the invitation of his classmate 'George', Murphy went to the abandoned logging yard after finishing the exhibition. When Murphy returned to his home and was located in the humble shack at 69 Heitie street, there was a faint shadow of a purple moon in the sky.

"Purple moon..."

Murmuring, Murphy hurriedly quickened his pace, entered the house and closed the door. Then he gently spit out his long breath.

In legend, the purple moon is often equated with evil. An example is that thugs and murderers always like to act at night.

Therefore, human beings in this world will not leave home at night unless necessary.

"Murphy? You're back. Why are you so late? What if you meet the 'black moon'?"

A young woman's voice came out of the compartment. It was his sister Joanne.

The so-called "black moon" refers to the days when there is no moon at all. In pure darkness, unspeakable terror will be born, and the missing person will never find a trace again.

"Sorry... Sister, there are activities at school today..."

Murphy instinctively lied. First, he hurriedly took off his school uniform and hung it up.

This is his only good clothes. He must hang them every day when he comes home to avoid wrinkles. He can't wear them to school the next day.

"There's bread in the closet..."

Joanne's voice came again, and immediately seemed to turn over and continue to sleep.

Murphy opened the closet and took out half a loaf of black bread, which was mixed with a lot of bran. The entrance was very rough and had to be soaked in hot soup before eating.

He thought for a moment and went to the stove to boil boiling water and served bread as dinner.

After barely fooling his stomach, Murphy came to his room.

There is only one bed and one table in the narrow house. The two sides are close together. The bed replaces the role of the chair. On the table, there are some abandoned metal parts. This is a "treasure" he picked up from nearby at the risk of being beaten.

In addition, there are several books that have been turned into some rags and the cover is shaking.

Murphy lit the gas light and sat on the bed.

Under the orange light, the names of the books are reflected:

A brief history of the world

Introduction to some simple machines

Standard language

"Night detective Castle - a collection of stories about the investigator 'Sauron'"

……

His sister Joanne is a great man. Using the savings left by his dead parents and the money earned from working hard, she sent him to Baixi machinery high school, which is the envy of the teenagers of the whole black iron street.

Once he can really study and graduate, he can become a junior mechanic. He doesn't have to be sent to the factory to work at a very young age like those little partners. He is bent down early by the heavy work and falls ill.

Murphy looked at the light and suddenly opened the "Introduction to some simple machinery", compared several waste metal components in his hand, and began mapping and learning.

But a moment later, distracted, he pushed his hand on the table and glanced over the investigator's story collection.

"The devil... Really doesn't exist?"

At the bottom of Murphy's heart, there has always been a little secret. He is an 'extraordinary person' with high natural sensitivity!

At a very young age, you can see some strange things and hear some sounds.

Even the night his parents' disappeared... He saw

At the thought of this, Murphy could not help rubbing his forehead and a painful expression appeared on his face: "I will find the truth, I swear!"

He muttered to himself.

But now Murphy is no longer in the mood to study mechanics and can only open some miscellaneous books.

He opened a brief history of the world and read it quickly.

"According to modern historians, the history of our world can be simply divided into purple moon and before purple moon... This is also the boundary between ancient history and modern history."

"In ancient times, the moon in the sky was not purple, and there was no 'black moon phenomenon'. Until the first purple moon appeared, a large number of bloodthirsty creatures were born in the wilderness, which directly led to the demise of the ancient brilliant Babylonian Empire... Ancient history ended."

"Since then, from the beginning of the purple lunar calendar, mankind has gone through an extremely dark period until the emergence of the famous mechanic and master qierfen, the founder of magic power instruments, created the first generation of magic power devices, and mankind has the power to resist bloodthirsty creatures!"

"In 223 of the purple calendar, the Sumerian empire was established, and the magic instrument division entered its heyday, with a glorious civilization of more than 1000 years... Until the famous' Rose coup 'broke out in 1567 of the purple calendar, and the Sumerian empire fell into an all-out civil war and disappeared..."

"In 1687, three kingdoms were established from the ruins of the Sumerian empire. They are the kingdom of Suriname in the north, the kingdom of SASS in the west, and the kingdom of Kingsley where I am."

"These three kingdoms have inherited and carried forward part of the heritage of Sumerian Empire, and embarked on different mechanical roads. For example, Kingsley Kingdom has improved 'biological mechanics' by generations of scientists, and the mechanical prosthesis made can perfectly replace the original flesh and blood officials. The magic pattern technology of Suriname kingdom is the most developed, and the kingdom of SASS is the most classical and conservative, But inherited the terrible legacy of ancient mechanics... "

"Countries use mechanical power to maintain their rule and fight against monsters in the wilderness... To this end, they have also established a special 'investigator' organization..."

Through reading, Murphy's expression gradually calmed down.

"But... Are the monsters known to mankind everything? Are there really no monsters that are not flesh and blood? What do I see?"

He muttered, yawned, turned off the gas light and lay in bed.

When he was about to fall asleep, Murphy seemed to see the "love in the starry sky" again.

……

"Yawn..."

early morning.

Murphy got up and stretched: "why did I feel so tired last night? I slept all night?"

He touched his head and felt his temples bulging. There seemed to be something more in his head.

Murphy came to the living room and found Joanne already making breakfast in her apron.

Seeing him, the other party's wine red pupils suddenly became suspicious: "didn't you sleep well last night?"

Joanne seemed to think of something. She ran to his room and opened the quilt.

"Sister... What are you doing?"

Murphy was confused.

"Cough... I think it's necessary to discuss with you the physical health problems of adolescent boys."

Joanne is very serious.

"I... I'm just a little late in reading..." Murphy replied with some guilty conscience.

"Really? Let me ask you, what are the construction elements of the second circuit magic pattern?"

"Stability! And enough white tin essence!"

Murphy blurted out and saw Joanne's surprised eyes.

He himself was surprised, because this was the knowledge he had not mastered.

Suddenly, he knew what was in his head.

That's knowledge!
