Looking around, Lacey saw that the room was filled with countless materials.

On the opposite side of the door was on the right, and on the right were all huge stones of strange shapes, and the two corners of the room were piled up quite high with burlap, and on the left were large wooden barrels, but everything seemed to be covered with dust.

However, Lacey's eyes were sharper, and he could see at a glance that the huge stones in the room were stacked with strange shapes.

Because all the stones as a whole are either gray crystals or white crystals, under the cover of the dust, the sun's rays penetrate through the door, and shine on the surface of the huge stone covered with dust, still with a vitreous luster.

"Grandpa Hall, let's go in and have a look!"

Lacey was full of doubts in his heart, and he couldn't believe what he had thought of, so he hurriedly greeted Butler Hall, and walked into the room alone, walking towards the huge crystalline pile that was strangely shaped like a stone.

Walking to the huge pile of crystals in the shape of stones, Reis took a towel to wipe off a piece of gray crystals in the form of stones with a dusty surface, and found that it really had a vitreous luster.

Butler Hall behind Reis looked at the saltpeter standing in front of him, full of curiosity about the whole piece of saltpeter, so he explained to Master Reis: "Young master, these stones are whole pieces of saltpeter, which are used as multicolored and pastel pigments in the dyeing workshop, and can also be used to make gunpowder. ”

"What saltpeter!" Lacey thought incredulously, and to be honest, Lacey couldn't believe that he would see a huge saltpeter crystal in the dyehouse.

I remember that in my junior high school studies, in the chemistry experiment class, in the saltpeter ice-making course taught by the teacher, Lacey also clearly saw the fist-sized gray saltpeter crystals, with a glass luster under the illumination of the light.

Compared with the huge saltpeter crystals that have just been irradiated by the sun's rays, the reflected glazed luster is exactly the same as the fist-sized glazed luster I saw when I was in junior high school.

Looking at the sun hanging high in the sky outside the house, feeling the blazing temperature in the air, and the sweat flowing in his clothes, Lacey wondered: shouldn't the family use saltpeter to make ice in such a hot weather?

Puzzled in his heart, Lacey pointed to the huge saltpeter crystalline and asked the hall butler: "Grandpa Hall, you said that this saltpeter is used as a raw material for making colorful and pastel, and for making gunpowder, so there is no other use?" ”

Hall looked at Young Master Lacey with a puzzled face, but still nodded and said: "Yes, young master, usually we use saltpeter as a raw material to make colorful and colored powder, as well as to make gunpowder, so there is no other use!" What's wrong? Master. ”

Hearing Hall's explanation, Lacey was a little confused, and couldn't figure out why a simple saltpeter ice was made without anyone knowing.

Lacey stood in place, looking at the huge saltpeter crystals in front of him, and fell into deep thought.

Through the memories he had seen in the past, Reis slowly recalled, only to realize that although the navy and the world government have industrial and technological means, the mainstream of the world is still the agricultural era.

Today's common people still live a life of sunrise and sunset.

The navy and the world government are very strict in protecting science and technology and knowledge, everything is just for themselves, and they don't care what kind of life the world lives.

Therefore, the navy is now crisscrossing the great voyage of steel ships, and the people of the world are still physical wooden ships.

In the age of agriculture, there was a lack of innovative ideas, and in addition to the treasure and protection of knowledge by the world government, the world was still ignorant.

I don't even know the simple method of making ice from saltpeter.

Scold! Thinking of this, Lacey, who understood the mainstream development of the world, couldn't help but smile, because Lacey found that most of the knowledge he had learned in his head for more than twenty years could be used in the One Piece world.

Butler Hall stared at Young Master Reis, who was standing in place and suddenly smirked, and wondered: "Young Master, there is nothing to see here, and the air is stuffy, let's go back!" ”

Although his thoughts were interrupted by Butler Hall, Lacey was still excited as he thought of a way to help the family through the difficult situation.

Pointing to the two gray saltpeter crystals the size of his fist in the ground, he said, "Grandpa Hall, can I take two saltpeter stones to play?" ”

"Take it, young master, the last thing the family lacks is saltpeter, and the business can't go on now, as long as you don't light a fire on the saltpeter."

Butler Hall didn't hesitate for a moment, and let Young Master Lacey take away two fist-sized gray saltpeter crystals.

Five-year-old Lacey, holding two fist-sized gray saltpeter crystals in his arms, left Hall's butler and ran quickly to his room on his lower legs under the protection of two new servants.

"Whew!"

Lacey, who returned to the room panting, threw two dusty saltpeter crystals on the lace cotton bed where he slept under the stunned looks of the two new servants, entered the bathroom alone, took half a basin of water with a basin, and staggered half a basin of water to the bedside.

Pointing to the two saltpeter crystals on the bed, he politely shouted to the two young new servants: "Two uncles, can you help me grind these two saltpeter into powder?" ”

Although they couldn't understand the appearance of a child suddenly shown by the always mature Young Master Reis, they naturally couldn't refuse Young Master Reis's request, so they happily agreed, and stepped forward and took out the small dagger on his waist.

Divide the two saltpeter crystals placed on the bed into one for each person, sit directly on the floor of the room, put the saltpeter crystals on the two pieces of white paper given by Master Reis, and use a small dagger to grind the gray saltpeter crystals into powder little by little.

"Young master, what are you doing here?"

The two new servants ground saltpeter crystals into powder, looked at Young Master Reis who was holding a pile of powder and smirked.

Reis looked at the two bewildered new servants and said funny: "I just want to have fun and see if the water will change color!" ”

After speaking, he poured a pile of saltpeter powder on the white paper in his hand into half a basin of cold water.

"Young master, saltpeter is used to directly make colorful and colored powder, how can there be poured into the water!"

"Young Master, you're not..."

Before one of the servants could finish speaking, he looked at the basin on the ground that suddenly made a gurgling sound, and exclaimed, "Ah, what's going on! ”

I saw that the basin placed on the ground, after Young Master Reis poured saltpeter powder, suddenly turned into a basin of ice as if it had changed magic, and appeared in front of the three of them.

Reis's idea is very simple, don't the people of the world know the method of making ice from saltpeter, so Reis asked his family to use the method of making ice from saltpeter to earn money and tide over the difficulties.

"Quick, quick, the two uncles are holding the basin, let's go find the father!"

Lacey wrapped another pile of saltpeter powder in white paper and grabbed it in his hand, and instructed the two new servants to carry the basin that had turned into ice cubes, and hurriedly left the room on the second floor and ran towards his father's study.

Because I couldn't figure out how many loyal and treacherous old servants in the Beirut family, Betsy and Gerson, whose names were actually brothers, were smoking stout cigars in their mouths in the gloomy study, and the whole study was full of white smoke.

The ashtray on the desk was piled with a pile of cigar butts, and I don't know how many cigars Becky and Gerson smoked in a short period of time.

Reis, who was running down the stairs to his father's study on the third floor, suddenly bumped into a sturdy body at the staircase on the third floor.

"Ouch!"

Because of the huge counter-impact, Lacey sat on the ground with a butt in the back, and his ass was full of pain.

"Ouch, Master Reis, are you alright?" The man with a sturdy body hurriedly squatted down, helped Young Master Reis up, patted the dust behind the buttocks of the young master's clothes, and asked with a concerned face.

Only then did Lacey discover that it was Nar, the son of Hall's housekeeper's grandfather, who knocked him down.

It's like Beirut. Reis, Beirut. Like Becky, the three characters of Beirut are family names, and Lacey and Becky are names.

So the full name of Hall Butler is Omiah. Hall, Nar's full name is Omiya. Nar.

Now Lacey, who is full of saltpeter ice, doesn't care why Uncle Nal appears on the third floor where he shouldn't be, you must know that Hall's housekeeper Grandpa and Uncle Nal's room is on the second floor.

No one on the third floor is allowed to enter the third floor except for himself, his sister, his mother, his father, Butler Hall, and Uncle Gerson.

Unfortunately, Lacey didn't think of this aspect at all, and thought it was Uncle Nal, who was called by his father, and looked at the white paper ball that was tightly dragged in his hand, and listened to the sound of two new servants ascending the stairs.

Lacey casually greeted Nar and hurried to his father's study.

Behind him, two new servants with ice cube basins also climbed to the third floor and followed Young Master Reis.

For the new servants, the entire Beirut family can naturally go anywhere, but for Nar, who is still standing at the staircase on the third floor, the two new servants don't have a good look!

Nar didn't know what was going on, but he laughed at the two new servants who were eyeing him, and turned and walked towards the second floor.

Bang! Bang! Bang!

At the closed door of the study, there was a sudden fierce knock on the door, and Lacey's immature cry was heard: "Father, open the door quickly, open the door quickly!" ”

What's going on? Becky and Gerson were puzzled, and they didn't know what had suddenly happened to the normally polite Lacey.

You know, the usual Lacey is smart, and under the teaching of his father Becky, Lacey has always abided by aristocratic etiquette, and will never make a lot of noise when the study is closed.

However, Becky and Gerson still snuffed out the cigars in their hands, and Gerson quickly got up from the sofa, straightened his clothes, and turned back to the strict appearance of a servant, and went to open the closed door of the study.
