Starting Today, I’ll Work as a City Lord

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

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

The last time Fox Er Niang wanted to try to make a cake, but she burned the pan in the kitchen. Fortunately, she used a fire extinguisher in time.

"Nicole covered her mouth and laughed, and everyone who was at the side saw it.

"Your Majesty, what materials are needed to make a simple fire extinguisher?" Mina asked doubtfully.

"You need dry powder and a container for it.

Liu Feng flipped around on the table, and finally took out a document full of materials from the bottom of the table and handed it to Mira.

He ordered, "Go to the scientific research department and ask them to prepare these materials. By the way, go to the workshop to get some glass bottles."

"Yes." Mira took the document with both hands, and then backed out.

When Liu Feng brought a fire extinguisher from the earth, he gave a fire extinguisher to the scientific research department and asked them to study what the main ingredients of the dry powder were, and whether they could find similar ingredients. After more than half a year, they finally had some clues.

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

Liu Feng also took it back to the earth for inspection, and found that some of these ore powders are consistent with the dry powder material in the dry fire extinguisher. Although they are not that powerful, 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 by gold coins, so it was put on hold. For a while, if it wasn't for the fire, he would have almost forgotten it.

"Let's go, let's go to the laboratory." Liu Feng got up and said.

"Tap Tat Tat...

After Liu Feng and others went down the eleventh floor, they got on the steam car and drove to the castle. Twenty minutes later, Liu Feng and others arrived at the castle's laboratory. Not long after, Mira also brought materials to the laboratory.

"Your Majesty, what should I do? Do you need help?" An Li was like a curious baby, looking left and right.

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

Liu Feng first took out a glass bottle, which was the size of ten soda cans, and the mouth of the bottle was not too big, but the size of a fist. After putting on gloves and a mask, he began to pour the materials brought back from the scientific research department into it.

"Your Majesty, what did you pour in?" An Li asked curiously while holding a pen. "This is dry powder, the main raw material for fire extinguishing. * Liu Feng explained. The glass jar was filled with dry powder in a short while. Liu Feng sealed the glass bottle with yellow mud, then handed it to Anli and the others, saying "Okay, after making Liu Feng, in addition to adding dry powder to the glass bottle, he also added a lot of special desiccant.

The desiccant is mainly some stone powder, which is also a new material developed by the scientific research department.

"Is this enough to put out the fire?" An Li asked doubtfully while holding the glass bottle.

"Try it."

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

"Okay." Enli nodded, and threw herself into the brazier.

research..

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 out." Enli said in surprise. "You guys should try it too." Liu Feng said with a light smile.

It can be regarded as an alien version of a simple fire extinguisher. Although it is not as easy to use as on the earth, it is still very useful for extinguishing some initial fires.

"Okay, I'm going to try it." An Li said in a crisp voice, and then put on gloves and a mask.

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

"-Remember to be careful, don't get too close." Liu Feng warned.

The main reason is that the glass fragments will be splashed. When the rubber processing technology is improved in the future, it can replace the glass bottle to hold the dry powder.

"Okay." Enli and Mina responded in unison.

The girls followed suit, picked up glass jars, poured desiccant into them, and sealed the jars.

"Your Majesty, we're done." An Li said cheerfully holding up the glass jar. "Try it and see if it works." Liu Feng signaled the maid to light the fire.

After the maid finished lighting the fire, An Li and Mina stood in front of the brazier. 3.8 and then - one by one, they carried out experiments. Each experiment would increase the fire a little bit. Liu Feng wanted to test how big the fire could be extinguished to the greatest extent. .

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

Liu Feng nodded in satisfaction, and then said, "Enli, let the workshop produce according to this simple method, mainly for the fire department." "Yes." Enli nodded, and then wrote in the notepad.

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

"Let the scientific research department study whether paper bags can be used instead of glass." Liu Feng said softly.

"Okay." Enri replied.

"Third shift, Cv7). Please customize, please support.".

Chapter 1163: The Flanders Empire arrives. (1 more for customization)

.crash...

On the sea, three hundred ships of the Flanders Empire were advancing.

At this moment, Princess Field was standing on the deck, with Green Deacon and Jin Mo standing on both sides respectfully.

"Your Highness, we still have a day's distance before we can see land." Green Deacon Hui reported.

"It's finally here." Field said softly. It has been more than a month since he went to sea, and life on the boat is not very good.

"Your Highness, shall we rest at the shore now?" Celtic Grand Knight asked respectfully.

Field turned and walked into the cabin, and then said, "No, not for the time being, if we continue on this route, we will go to Haiyan City first."

"Go to Haiyan City first?" The Celtic grand knight heard more or less about this city from Deacon Green and the others on the way here.

Field took the buckwheat wine poured by Jin Mo, and said, "Well, among the coastal cities, Haiyan City has the largest area."

Before returning to the Flandre Empire in 01, Field stayed in Haiyan City for a while, and still liked this city very much.

The Celtic knight thought for a while, then asked respectfully, "Your Highness, are we planning to stop at Haiyan City?"

"Let's send someone in a boat to find out, we've already left" - it's been a while, and no one can tell what's going on there now. ' Commanded Field.

"Yes, Your Highness." The Celtic Grand Knight nodded.

Field took a sip of the buckwheat tea, and then added, "By the way, order the three hundred ships to rest in place, and make plans after the knights come back from investigation."

She is not a stunned young man, she still has some basic marching knowledge. "Understood." The great Celtic knight said respectfully, and then exited the cabin.

"Tap Tat Tat...

When he came to the board, he summoned the knights of the main ship.
