Become the city lord from today

"Knock knock..."

The bell of Chang'an City for a new day has woken up, and today Liu Feng will be outside all morning to inspect.

Mira got out of the car and opened the door, respectfully saying, "Your Majesty, we have arrived." "

After coming out of the castle, the first place to inspect was the Grand Theater, which is now equipped with electric lights, so he needs to see how it is.

"Hmm." Liu Feng nodded lightly.

After Mila first took people in to inspect and guard, Liu Feng walked in with several women.

"Your Majesty." The person in charge of the Grand Theater and the technical staff of the Scientific Research Department said respectfully.

"Well, how's the light installed?" Liu Feng asked.

The Grand Theater to install electric lights has long been on the agenda, but helplessness is a technical problem, it has not been overcome for a long time, and some time ago there was a bit of eyebrows.

The technical staff of the Scientific Research Department saluted and said respectfully, "Your Majesty, everything has been installed, wait for Your Majesty to accept the results." "

Originally, Liu Feng had thought of moving a generator directly from the other side of the earth, but this is not a long-term solution, what if it is broken? This still depends on the people of the scientific research department to develop ah.

No, they were given a drawing of the generator, which marked how to make it, and the principle of power generation, etc., which were clearly marked.

"Well, I'll take a look." Liu Feng nodded lightly.

"Yes, Your Majesty." The technician answered immediately.

The generator covered with a red cloth was the first to lift, a large generator one meter high and one meter wide, the appearance did not look good, I saw an atmospheric cylinder in the middle, and there were many wires connected around it.

"Your Majesty, this generator uses black oil fruit as fuel." The technician explained.

"If you want electricity for a stage play, how many black oil nuts do you need?" Liu Feng wanted to find out the consumption of this generator.

"Back to Your Majesty, it takes almost four black oil fruits." The technician said respectfully.

"Okay, let's get started." Liu Feng nodded lightly.

"Yes." The technician immediately answered and began to tinker with his assistant.

The assistant placed black oil nuts one by one, began to drive the generator to run, and the mixed gas in the cylinder burned violently, and the volume expanded rapidly, pushing the plug downward to do work.

The thrust acting on the plug becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate, using the principle of 'electromagnetic induction'.

Under the operation of the technician, the engine ran quickly, and the bulbs connected to the engine began to light up one by one, and in less than a minute, the dozen bulbs connected to it all lit up

The light hit Allie's face and said in surprise, "Your Majesty, it's so bright." "

"It seems that the Grand Theater can also have lights." Mina looked around in surprise.

Liu Feng looked at the bright light and nodded with satisfaction, and praised, "You guys are good." "

"It was His Majesty who gave the drawings very carefully." The technician salutes modestly.

Liu Feng walked to the generator, looked at this behemoth, and asked, "But this sound is a little louder, and the volume is also it, and it is slowly improved in the later stage." "

"Yes, Your Majesty." The technician answered immediately.

"Experiment a few times to make sure there are no hidden dangers before putting it into use." Liu Feng instructed solemnly.

After all, the first generator has just been made, many places are not perfect, may not be stable, or need to be carefully observed and improved.

"Understood." The technician nodded quickly.

Liu Feng looked around the surrounding environment and instructed, "The arrangement of this lamp needs to be improved, and the light shines unevenly." "

"Yes, Your Majesty." The person in charge of the Grand Theater immediately answered.

Liu Feng walked around the Grand Theater for another ten minutes, and after giving a few precautions, he left the Grand Theater with a few women, preparing to go to the old city to inspect the progress of the sewers.

Twenty minutes later, the steam car stopped in the old square, and Mira respectfully opened the door.

Liu Feng sorted out his clothes and stood on the edge of the square looking at the street.

An Li looked at the fence fence one after another, and said with a smile, "Your Majesty, although it is under construction, it has not hindered the traffic at all." "

"The roads in Chang'an City extend in all directions, as long as you know in advance where the construction will begin, it is good to take a detour." Liu Feng smiled.

"Your Majesty, why is this sewer laid with so much iron? Isn't it nice to have cement? Mina wondered.

Liu Feng rubbed the cat's ear girl's head and explained, "If the cement alone is not able to withstand the violent impact of the water flow, otherwise it will be broken all at once, and adding iron into it is different, and the force point will be better." "

"So it is." Mina suddenly realized.

"Let's go, go and see." Liu Feng walked in front first.

Escorted by Mira, several men entered the fence and watched as the craftsmen laid the cover on it.

"Your Majesty, why is this cover round, not square or other shape?" Mina wondered.

Liu Feng smiled slightly and explained, "From an engineering point of view, the round manhole cover can evenly disperse the load, the cylindrical shape can best withstand the pressure of the surrounding land, and the long-term crushing of horse-drawn carriages and steam cars will not be deformed." "

"It turns out that this shape has such a big knowledge!" Mina said in amazement.

Allie took the notepad and wrote carefully, feeling that this was a rare knowledge point, but he had never thought about this problem before.

"Allie, how is the sewer link between the households?" Liu Feng asked.

It used to be a drainage canal, but now that the sewer has been laid, the most important step is to link the households, and later it is necessary to enter the drainage project.

This requires preparing for drainage in advance, and if it is time to lay the faucet, it will be a bit redundant to relink.

"Every family has already agreed, and the work will proceed immediately." Allie looked at the notepad.

Liu Feng nodded in satisfaction and said, "Wait, the faucet can also be popularized soon." "

"Chang'an City is really getting better and better, they can also use the faucet, so they don't have to carry water anymore." Allie said with a smile.

"yes." Liu Feng said gently.
