Happy days are always so short, while unhappy days are long and have no end in sight.

Why is that?

Alvin pondered the question for no reason as he followed Scade.

Alvin looked at Skade and sighed that this young magician, who had not seen him in just a few days, was already full of silver frost.

"It can't be dyed, right?"

The gray hair made Skade a little more old and stable.

When Alvin looked at this kid, he couldn't help but secretly suspect that the relationship between him and Leon would not be beyond the ordinary relationship, right?

However, thinking of Lord Lord's current position, Alvin couldn't help but snicker.

"This is it!"

Skade pushed open a door a few meters high, pulling his old wound too hard, and couldn't help coughing repeatedly, the heart-rending coughing sound made Alvin doubt that he would have a few days to live.

It seems that in the future, it will be more important to attack and directly kill the enemy, so as to save others from suffering like this.

"I ......"

Alvin was stunned by the scene before him.

In a huge indoor square, hundreds of people were busy like ants around a huge magic array.

Ms. Shipton, who had been following Alvin steadily, shook Alvin out of the way with one arm and squeezed through the door.

Then it kept appearing in all corners of the magic array.

"This stabilizer is magnified tenfold...... No, it's twenty times, and the feed port is so small, how much manpower does it take. ”

"So that's the case, anyway, the Galistone is already so unstable, so I simply use the smallest size to control the energy of a single Galistone in the smallest range!"

"Bastard, how many controllers do you need to work together to reach the magic threshold?!"

"Waste, waste, it's a huge waste."

Everywhere Ms. Shipton went, she let out a heart-wrenching lament.

By the end, she was numb.

Alvin walked up to Skyde, and although the smile on the other party's face was very restrained, he still couldn't hide it.

Ms. Shipton, who had been hit hard by the other party's financial resources, walked over in silence, sad.

She was knocked down by money!

Alvin looked at the scene in front of him, silent, thoughtful.

Skyd beeped, "Ladies and gentlemen, Storm City's greatest secret is right before your eyes. Whether you can really discover it or not depends on your discernment. ”

Ms. Shipton, who felt that it would be difficult to replicate everything in front of her, listened carefully to Skade's words.

Alvin sneered.

"Trick up!"

Alvin could see it at a glance.

It's just another form of physical experiment.

Design well in theory first.

Then, the results are obtained through experiments, and then the whole process is continuously decomposed, and all the materials in each link are replaced until the optimal solution is found.

To put it bluntly, it's cost control.

The inventor of the light bulb was Henri Goebbels, who was born in Germany as an inventor of precision mechanics and immigrated to the United States in 1848. In 1854, Henri Goebbels used a carbonized bamboo wire and placed it under a vacuum glass bottle to electrify and glow. Henri Goebbels had already invented the same principles and materials decades before Edison. Edison, on the other hand, was an improver.

In the beginning, the light bulb was an arc lamp made of 2,000 batteries and two charcoal rods. But its light is too strong to be suitable for home use at all. Edison experimented with more than 1,600 materials, and in 1880, Edison's carbonized bamboo silk bulb was successfully maintained in the laboratory for 1,200 hours. The incandescent lamp invented by Edison is of high quality and low price, and is very popular with the public. It wasn't until 1904 that General Electric invented a tungsten lamp that was three times stronger than a bamboo lamp, and this black wire lamp has been in use since 1907. So, the light bulb was first invented by Henri Goebbels, and Edison invented and improved the incandescent lamp later.

The reason why everyone always associates the light bulb with Edison is precisely because it is Edison's improvement that makes ordinary families can use electricity, and it can be said that he has made a significant contribution to the improvement of the light bulb.

In the laboratory, regardless of the cost, human beings can do more than ordinary people can imagine, but to industrialize the results of experimental research is a long process.

And at this point, unless you have a golden finger, or also from the future, then there is no shortcut. Edison experimented with more than 1,600 materials before finding the cheapest wick.

Cost, cost is everything.

It has to be said that in this era when even nobles don't necessarily know how to read, Lord Leon has found a fairly scientific experimental method of magic research.

This thing in itself is quite unscientific.

Alvin looked at Skade and thought to himself, Leon couldn't have also traveled through time, right?

Alvin was already able to see that one day in the future, all the magic items of this era would be produced in batches from one production line to another.

This is the power of industrialization.

When the first machine was built, it had to be by hand.

But when humans use machines to make machines, the technological process of human beings has already turned on the accelerator.

A photo on the Internet is particularly shocking, who would have thought that it took only 66 years from the plane to the sky (1903) to the first human landing on the moon (1969).

No wonder a great man said that when primitive humans looked up at the starry sky, they were only one step away from revealing the ultimate mystery of the universe!

Alvin has reason to believe that if Lord Leon is given enough conditions, one day, the humans of this world will take the portal out of their pockets and cross over to Mars in one step.

Ms. Shipton studied for a long time, but still could not find anything valuable.

Alvin regrets, but is also relieved. The gap between the two people's vision is across the era, and this has nothing to do with wisdom.

Seeing the triumphant Skade, Alvin was furious for a while.

He punched Skade in the stomach, causing the former to bend like a prawn.

"When can the magic circle be opened?"

Alvin found out that he was too much to give this person face.

"Thirty days, I can guarantee the safe operation of the magic array!"

Skade started coughing again, probably from being beaten.

"Three days! In three days, I'm going to see the portal open. I can't see it, I'll assemble it for you. ”

If I'm well, I'm Optimus Prime, and if I'm not, he's a broken corpse.

Skade was speechless with rage.

Alvin turned and left.

Why don't you leave here? He couldn't understand the principle anyway, and don't forget, he was a magic apprentice who hadn't been regularized for three years.

Miss Shipton caught up.

"Alvin......" Ms. saw that there was no one behind her, and then whispered: "Three days, the time is indeed too short." There's no way to do it, so why bother Skade? ”

Alvin saw that there was no one around, so he showed a treacherous smile: "It's because he can't do it at all that I say this." In this way, all his energy is devoted to the magic array, and there is no time to fight those bad ideas. We're still in the wolf's den, after all! ”

Ms. Shipton looked at Alvin with an unrecognizable look, "You seem to have changed a lot lately?" ”

Alvin was about to say that the maturity of men is so coquettish.

But I didn't want Ms. Shipton to say: "It seems that the virgin body is a kind of seal on the wisdom of men!" ”

When Alvin heard this, he was ashamed of himself and fled.

Ms. Shipton looked at Alvin's back and said silently, "And women, only in the face of infidelity, can burst out with amazing intelligence. ”
