Become the city lord from today

Mina took a few drawings and said, "Your Majesty, isn't this similar to the red fire extinguisher in the castle?" "

Liu Feng brought several cans of fire extinguishers from the other side of the earth and placed them in some important places in the castle, as well as important places such as study rooms and rooms.

"Well, it's just that this fire extinguisher can only be used for castles, tallest buildings, and grand theaters for the time being, and the rest needs a lot of research and development." Liu Feng said softly.

"Your Majesty, do you want to promote it?" Allie wondered.

"Promote some simple fire extinguishers, we can make them ourselves, and after these developments on the drawings, let's leave them to the fire department." Liu Feng said lightly.

"Make it yourself? Can we make this red jar ourselves? "Nicole is interested.

"We can only make some simple, red jars or let the Ministry of Scientific Research get them," Liu Feng chuckled.

To make a regular dry powder fire extinguisher, the required procedure is more troublesome, welding alone this program can not be operated by themselves, or need professional people to get it

"Are these red can fire extinguishers going to be hard to use?" Mina wondered.

The castle has a fire extinguisher, but the cat-eared lady has not touched it, and the last time Liu Feng taught, she had something to go out.

"It's simple, it's not difficult at all, everyone can learn it." Liu Feng said with a chuckle.

Allie suddenly blushed, paused for a while and said, "This is really simple, I tried it last time." "

Last time the fox girl wanted to try to make a cake, but she burned the kitchen pot, but fortunately she used a fire extinguisher in time.

Nicole covered her mouth and laughed, all of her eyes at the time.

"Your Majesty, is there any material needed to make a simple fire extinguisher?" Mina wondered.

"Need dry powder and containers for dry powder."

Liu Feng flipped on the table, and finally at the bottom of the table, he pulled out a document full of materials and handed it to Mira.

He ordered, "You go to the scientific research department, let them prepare these materials, and by the way, go to the workshop and get a few glass bottles." "

"Yes." Mira took the document with both hands, then withdrew.

When Liu Feng brought a fire extinguisher from the earth, he gave the scientific research department a fire extinguisher, let them study what the main ingredients of the dry powder are inside, and whether they can find similar ingredients, and it took more than half a year to finally have a little eyebrows.

They found several kinds of ores, and then ground all these ores into powder, and mixed them together to have the current dry powder.

Liu Feng also took it back to the earth to test, and found that these ore powders are consistent with some of the dry powder materials in the dry fire extinguisher, although they are not so powerful, but they can also play a role in extinguishing fires.

Although the dry powder was developed, the production cost of the fire extinguisher was too high, let alone calculated according to gold coins, so it was put on hold for a while, if it were not for the occurrence of this fire, he would have forgotten.

"Let's go, let's go to the lab. Body.

"Tread, tread..."

After Liu Feng and the others got down to the eleventh floor, they took the car and drove to the castle.

Twenty minutes later, Liu Feng and the others arrived at the laboratory of the castle, and not long after, Mira also arrived at the laboratory with the materials.

"Your Majesty, what do you want to do, do you need help?" Allie was next to her like a curious baby, looking left and right.

"No need." Liu Feng chuckled and shook his head.

Liu Feng first took out a glass bottle, the volume was the size of ten cans, the mouth of the bottle was not very large, it was the size of a fist, after wearing gloves and masks, he began to pour the materials brought back from the scientific research department.

"Your Majesty, what did you pour in?" Allie held the pen and said curiously.

"This is dry powder, the main raw material for extinguishing fires." Liu Feng explained.

The glass jar was filled with dry powder after a while, and Liu Feng sealed the mouth of the glass bottle with yellow mud, then handed it to Allie and said, "Okay, it's made." "

In addition to adding dry powder to the glass bottle, Liu Feng also added a lot of special desiccant.

The desiccant, mainly some stone powder, is also a newly developed material of the Ministry of Scientific Research.

"Does this put out the fire?" Allie held the glass bottle and wondered.

"Try it."

Liu Feng asked the maid to light a fire in the brazier next to him, and then said to An Li, "Throw it in, use some force." "

"Good." Allie nodded and threw herself into the brazier.

"Bang..."

As the glass bottle shattered, all the dry powder inside ran out, and the fire in the brazier was slowly extinguished.

"Your Majesty, the fire is really extinguished." Allie was surprised.

"Try it too." Liu Feng chuckled.

It can be regarded as an otherworldly version of a simple fire extinguisher, although it is not as good as the one on the other side of the earth, but it is still very useful to extinguish some initial fires.

"Okay, I'll try it." Allie's crisp voice sounded, and she also put on gloves and masks.

"I'll come too." Mina said eagerly.

"You must remember to be careful, don't get too close." Liu Feng instructed.

Mainly afraid of glass shards splashing, when the rubber treatment technology goes further, it can replace the glass bottle to fill the dry powder.

"Good." Allie and Mina answered in unison.

Several women followed suit, picked up glass jars one by one, poured desiccant into them, and then sealed the mouth of the bottle.

"Your Majesty, we are ready." Allie said cheerfully as she held up the glass jar.

"Let's try it all and see if it works." Liu Feng signaled the maid to light the fire.

As the maid finished lighting the fire, Allie and Mina stood in front of the brazier, and then carried out experiments one by one, each experiment would increase the fire a little, Liu Feng was to test how much fire could be extinguished as much as possible.

"Your Majesty, ours can also extinguish the fire." Mina said with a smile.

Liu Feng nodded in satisfaction, and then said, "Allie, let the workshop produce according to this simple method, mainly supplied to the fire department." "

"Yes." Allie nodded, and then wrote on the notepad.

"Your Majesty, wouldn't this be too much of a waste of glass?" Nicole hesitated.

"Let the Ministry of Scientific Research study whether paper bags can be used instead of glass." Liu Feng said softly.

"Okay." Allie replied.
