The construction of street lights has begun in a low-key manner and has not been officially disclosed to the public yet. Fesden led a team to start researching light bulbs. They are preparing to increase the life of the light bulbs to 500 hours, so that they are suitable for commercial use.

Street lights last much longer than ordinary household use. Even if it takes 500 hours, calculated from 10 to 14 hours a day, a light bulb can only be used for more than a month.

Jiayi did not spend much energy on this, but just proposed to Fessendon to try using tungsten. This metal has a high melting point and can theoretically be used for a longer period of time.

He is now busy making wings for himself.

While traveling, he encountered a group of bandits. The barbarian among them used a big sword, and Lan Yujin was used in the big sword. In the end, the big sword became his trophy. The barbarian was sent to Cargine as his attendant.

Lan Yujin is a very lightweight metal, but it is very hard and has certain magical deduction ability.

He extracted the Lanyu gold in the great sword, added titanium gold, nickel alloy to make an alloy and then made a feather piece, and then used mountain copper and blood-branded steel alloy to make a hollow skeleton. The feather piece was embedded one by one on the skeleton, and it became a pair of metal wings. The edges of the feather piece were plated with a layer of pure gold to ensure it was sharp enough. The angel's true feather was embedded at the root of the right skeleton and was hidden in the metal feather.

Queenie helped him design the entire wing array, allowing all the metal feathers to become one with the entire wing, not only to fly, but also to shoot out as a flying knife.

The latest street lights have not been designed successfully, and Jiayi’s flying props have finally been made.

The wings are silver-white all over. The skeleton is filled with blood-red patterns due to blood-blocking steel. It is like blood vessels, and it doesn't look like a good person. Jiayi specially plated a layer of chrome on the outside to hide the blood-blocking patterns and also cover the magic patterns.

A good-looking image can help avoid many troubles, such as many mages in the undead. Although they are not very different from ordinary mages, most people always have some fear and prejudice against mages in the undead.

Queenie helped Jiayi install the feather pieces on the skeleton one by one. Each feather piece uses a hidden artifact to hide the magic circle inside the feather piece, which can better protect the magic circle inside the feather piece from damage and also has better aerodynamic performance.

The two of them assembled the wings together, and Kaichi lifted the wings: "Let's go out and try it."

The two walked out of the laboratory together and came to the open space outside the house. Fortunately, Jiayi's house belongs to the suburbs of the city, and the small hills around his house belong to the scope of the house and are not within the no-fly area, otherwise they would have to run far.

Jiayi opened the magic circle in the manor and said to Queenie: "It's just a matter of trying to see how the defensive magic circle you arranged is. You should be gentler and don't destroy my home."

Although he had confidence in Queenie's defensive magic circle, he did not dare to let Queenie go completely. Even if she could bear it, she could not bear it himself.

Jiayi activated his wings, and the skeleton at the base of the wings immediately absorbed on Jiayi's back, then extended forward, extending from his shoulders and armpits to his chest, wrapping it up, a bit like a shrinking vest, while the entire pair of wings seemed to grow on his back.

He really wanted this pair of wings to be able to be stored in his body like a legendary magic weapon, but he confirmed several times to Queenie that there was no such technology here, unless the equipment was energized, this was not something that Jiayi and Queenie could solve. He could only specially optimize the equipment time of wings. The equipment on wings is no more than two seconds, which is almost enough.

After finishing his dress, Jia Yi jumped up, like a monkey jumping out all of a sudden.

Jiayi, who was rushing into the sky, was like a drunk wild pigeon, shaking and unable to find the direction. Queenie was worried when she looked down: "Jiayi, can you? Low... don't you better fly higher, be careful to hit the ground."

Jiayi spread his hands and stretched out his wings at the same time, stabbing his body in the air: "It's okay, I want to get familiar with it."

This pair of wings is not difficult to control. It is like two arms growing again through spell connections, but these two arms are a little numb and are not flexible to control. Fortunately, he has the experience of manipulating his tentacles. After getting familiar with them for a while, he can roughly control the wings to make movements.

This pair of big wings not only provides buoyancy, but also helps him better maintain stability in the air. He quickly dives down from mid-air, stretches quickly when approaching the ground, and then draws 8 characters in mid-air, like a huge hawk.

A layer of protective cover extended from the root of the wings to raise Jiayi's valley, helping him block the strong wind that was coming, and at the same time effectively lowered the wind resistance and made the speed faster. I wonder if Angel Masao really had a miraculous effect on the speed bonus. The wings flew much faster than Jiayi imagined, and at least three times faster than he used his own flight technique.

Although it is not as good as a legendary wizard who can tear open space and teleport, ordinary purple-robed wizards cannot catch up with him.

"So fast." He stopped in the air and looked down at Queenie below, "Be careful, I want to try to see if the winged knife is easy to use."

As he said that, Jia Yi suddenly thrust downwards, and when he was halfway through, feathers flew up at the ends of his wings and shot towards Queenie, several times faster than the speed of the wind blade.

A magic shield was supported in front of Queenie, and at the same time, a red light flashed out of her hand. The flying knife was knocked away by her, and the rest was shot onto the shield, shaking the shield. It was not until Queenie increased her magic power on the shield that she stabilized the shield.

Jiayi shot out hundreds of flying knives one by one before stopping, then flew to Queenie, and the flying knives flew back one after another and were re-embedded on the skeleton of the wings.

"It seems that the attack of this wing is like a good person, with no effect at all."

He was a little disappointed with the attack power of these flying knives. He specially attached a magic circle effect to the flying knives, and there was also a gold coating on the edges. In theory, the attack power should be good.

Queenie put away the shield: "It's already very good. If I hadn't enhanced the shield, the shield had been broken now. For the white-robed mage, the lethality is no longer weak."

As a disciple of the legendary wizard, Queenie also has some good things on her.

"Then I can only abuse the food, fortunately, at least it looks good."

Queenie said angrily: "Your requirements are quite high. Unless it is some powerful props, it is basically impossible for you to pose enough threat to a purple-robed mage. However, if such props are probably the one who dies first."

Although Jiayi has seen more than one legendary wizard, in fact, the most powerful wizard that ordinary wizards can come into contact with is the purple-robed wizard. Otherwise, Fesden would not have attached so much importance to the tasks of the Supreme Council, because it was arranged by Wilmot himself.

"But your flying knife is good. I just increased my magic power and didn't destroy it. I thought at least the internal magic array would be affected and I couldn't fly. The magic array inside your flying knife is not exquisite, and it was a lot of trouble when etching the magic array."

Jiayi spread his wings and stretched his wings in front of him: "It is because of the complexity that there is such good stability. The redundant magic array I specially designed will not affect the use as long as the magic array is damaged by no more than one-third. Moreover, these feathers also have an automatic recovery function. As long as they are not broken, they can slowly recover even if they are deformed. If the attack power is higher, it is simply perfect."

Although Jiayi has made a lot of efforts, only the core angel feathers inside can be considered precious. Although the other materials are good, they have not reached the level of qualitative change. Only by relying on the current flight speed can it be considered as a loss. Other fancy functions are at most icing on the cake.

This pair of wings is a concentrated reflection of all skills mastered by Jiayi. The skeleton of the wing uses demon runes that have not been fully mastered, plus the core of the ancient magic text constructed by Queenie. The demon runes are effective in combination with angel feathers, which can better stimulate the energy in the angel feathers. The array is modular between the feathers and the skeleton. Even these alloys are high-quality alloys restored from mechanical puppets, especially the automatic recovery alloy of feathers. This is the core of mechanical puppets that can maintain long-term use. They can be used by statically using magic recovery alloys.

Although he was a little nitpicking, Queenie felt that this was the ultimate they could do. If you want better, you can only use better materials.

After testing the wings, Queenie asked, "I saw you list many elements on the manuscript paper in your laboratory. What are you doing?"

"I want to find out the rules between these elements, but they don't seem easy to find, and they are still sorting out and not completed. I think these elements should have periodic rules, but they are not perfect now."

"It's not easy. You are not the first to think so, but there is no one who succeeds. No rule that anyone has summarized can be recognized by everyone."
