There are lighting objects similar to fluorite lamps and night pearls in the immortal cultivation world, but whether it is a fluorite lamp or a night pearl, the light is relatively weak.

Electric Feather always felt that after being active in this light for a long time, even monks were prone to short-sightedness, so Electric Feather hit the idea on the light bulb.

She began to recall the construction of the light bulb in her previous life, and she remembered that when she was in history class in junior high school, she happened to have a lesson about Edison's invention of the light bulb.

Their history teacher introduced that Edison's invention of the electric light bulb was a layer of transparent, thin glass on the outside, and the inside was pumped into a vacuum, and the filament in the middle could emit light when it was energized.

And it is said that the first filament was made of several carbonized bamboo wires, because carbon conducts electricity and has a very high melting point.

She was still very shocked at the time, bamboo silk can be made into filament, and it emits such a dazzling light, so that she was very impressed.

Later, an Austrian who could no longer remember the name of the electric feather invented a tungsten lamp that was three times stronger than a bamboo wire lamp, and the tungsten wire replaced the carbonized bamboo wire and became the tungsten incandescent lamp familiar to later generations.

After reminiscing, Denyu went to find Kuki, who was studying the formation alone, and told Kumu about his ideas.

Kuki, who had already turned into a scientific research maniac, heard that there was a new research project, and his eyes instantly glowed with a dazzling light like the light bulb they were about to develop.

When they decided to make a light bulb, they first started with the material of the lampshade on the outside.

It's too fragile to use glass, and in this popular cultivation world where violence is countered with violence, I'm afraid I won't survive an episode.

After many experiments, they found a more suitable material in the Immortal Cultivation Realm.

It is an ore called gray spar, which looks gray on the outside, and when polished, it will show a delicate light gray luster.

This kind of ore is a very common one in the cultivation realm, because of its hard texture and low-key and calm color, the natives of the cultivation world generally polish it directly and use it to lay the floors of large buildings such as halls and underground palaces.

The electric plume urges the earth fire to melt the gray crystal at high temperatures, and after removing impurities, the liquid begins to become transparent, it can be shaped like glass, and this material is less difficult to break than glass after molding.

The material of the lampshade outside is solved, and the next thing is the filament.

There is no metal that can make tungsten filament in the immortal cultivation world, but the metal in the immortal cultivation world is more than a hundred times more than that of the earth, and it is definitely not difficult to find a material to replace tungsten wire, but it just takes time.

They took all the materials they had access to and tried them one by one.

Just when they were looking for materials like a needle in a haystack, they met Senior Brother Hu Ming, who had been ordered by Elder Yiyang to come to deliver the "Cultivation Technique" exclusive to the inner disciples of Dian Yu.

Senior Brother Hu Ming didn't know what he was doing when he saw Electric Yu and Kongmu Ping Pong, but he was very curious when he thought that Electric Yu could refine some strange magic weapons with ingenuity every time.

After asking, he learned about Dianyu's thoughts, and he, who already loves to specialize in refining tools, immediately geared up, saying how could he be missing, so he also joined the research and development with great interest.

Senior Brother Hu Ming was originally an inner disciple of the Refining Weapon Peak, and his current refining level was much higher than that of the novice rookie Electric Yu.

And he usually likes to specialize in refining tools, and he has listed dozens of materials that can replace tungsten wire for various refining materials.

With the addition of Senior Brother Hu Ming, a professional refiner, they took many detours, and after the control experiment of each material, they quickly found the most suitable metal to replace tungsten wire.

The three of them have become obsessed with studying light bulbs, often leaving early and returning late.

Yuci came out several times to look for the late return of Dianyu, watching the busy junior brothers and sisters, watching from the side for a few days, and also joined in with great interest, and began to take on the role of light bulb appearance designer.

After half a month of repeated operations and experiments, the first light bulb in the Xiuzhen world finally came out!

If it weren't for the fact that there was no Senior Brother Hu Ming in the early stage, Dian Yu and Kong Mu blindly groped and wasted a lot of time, otherwise it might have been faster.

Because of the feelings of the previous life, under the strong request of the electric feather, the shape of the first born light bulb was made into the original round shape of the electric light bulb in the previous life.

Through the round, dazzling light bulb, Dianyu seemed to see Edison's sparsely white-haired, round head in the textbook, and almost cried with joy.

Although the other three were puzzled why Dianyu was so obsessed with making the bulb into the shape of a urine bubble, they looked at the bulb that they had worked so hard to make, and watched the bright light illuminate every corner of the room, as if they could sweep away all the gloom, and a sense of accomplishment arose.

Hu Ming stretched out a hand and waved it slowly, delighted at his clear shadow in the light.

It's amazing to be able to see shadows that only appear clearly under the sun in the dark!

The bulb has been made, and the next step is to enter the product trial stage.

After repeated trials and carvings, Kongmu also added a light expansion array to it, which can obtain a larger light source under the same energy output of spirit stones, so as to maximize the use of spirit stones and save spirit stones.

Brother Hu Ming referred to the principle of the previous production of the electric feather air conditioner, and added a twisted control beam that can rotate the light expansion array outside, which can be used to control and adjust the intensity of the light, and also added a blocking switch on the air conditioner.

Senior Sister Yuci has recently been obsessed with flowers and plants, and has designed various lamps related to the shape of flowers and plants with reference to the illustrated books in the library library.

Dianyu picked up one of the design drawings and looked at it, and was shocked!

This pedestal! This bellflower! This receptacle! Isn't this the Baolian lamp of the Three Virgins of Huashan?!

If it weren't for the fact that he had been with Yuci for a long time and knew that she was a genuine native of the Xiuzhen Realm, Dianyu would have almost wondered if she had traveled from the modern era.

But to be honest, these designs of Senior Sister Yuci are still very beautiful, they look very elegant and chic, and Dianyu herself wants to buy them.

However, these flowers and plants seem to be more suitable for women, and at the suggestion of Dianyu, Senior Sister Yuci has designed some tough and domineering electric lights suitable for men.

After making sure that there was no problem, they sorted out the production drawings and methods, and found several refining brothers who had become the leaders of their exclusive production team, so that they could start producing a batch of goods in small quantities first.

Everything was ready, and just as they were about to release the bulbs for sale, a very tricky question arose.
