The technique of delta wing is too simple for anyone to do, but to do it well and exquisitely, it has to be Reinhardt.

This famous master forge of the Guild of the Dead has devoted himself to the improvement of the delta wing.

First of all, he modified the seamless pipes, opened several air intakes without affecting the structural strength, and engraved the magic pattern of the lightness of the wind on the surface of the steel pipes.

When the delta wing flies, a large number of wind elements collide with the magic patterns on the surface, which will activate the effect of light wind, thus greatly increasing the load capacity of the delta wing.

At the same time, the wind element is poured through the opening of the seamless tube, which compresses and ejects out, thus giving the delta wing a forward propulsion, and the faster the speed, the greater this propulsion.

Combined with the pedal power of the delta wing itself, the speed is as fast as Gray would have accelerated with wind magic.

Third, the silk cloth used in the delta wing is sprayed with a thin layer of defensive paint to enhance its strength and wind-riding performance.

Fourth, the wooden spiral pulp is also engraved with the rune of wind concentration, the spiral pulp rotates to activate the concentration of wind, and the surrounding wind elements will collectively converge to the tail, producing a jet propulsion effect, which greatly increases the thrust-to-weight ratio.

After several improvements, the flight speed and load of the delta wing have been improved across the board, but the corresponding cost has also soared, especially for the propellers that require steel tubes with inscribed runes.

Magicians are noble and rare, and as long as they involve magic, they must be expensive and difficult to do. Reinhardt is a master blacksmith, and he casually forges a piece of weapons and equipment, all of which are tens of thousands of gold.

The living expenses of ordinary farmers are only one or two gold a year, and ten peasant families may not be able to afford a magician.

Reinhardt's idea is good, but where did Luo Qiu get so many magicians to engrave runes?

......

Luo Qiu threw the matter of improving the production of the flying wing to Reinhardt, and he took Gray and the other two undead saints, as well as twenty silver skeletons, and flew the flying wing to the seashore four hundred kilometers northeast of the Iron City.

The flight carrier is available, and the rest is the air weapon, Luo Qiu originally wanted to get the black powder out, but found that the power of the black powder was not enough, and the flame explosion technique of any fire magician was far more powerful than the bomb of black powder.

This is also the reason why Luo Qiu has never made a musket, the power and range of the musket of black powder are too low, the maximum range of his cave wind bow is four kilometers, and the gaze lock can be three kilometers, even with ordinary arrows, there is a range of a few kilometers.

What is the range of the black powder musket? 300 meters.

In the world of magicians, black powder is useless, but he can't get high-speed gunpowder, and in the absence of three acids and two alkalis, trying to make high-speed gunpowder is equivalent to a fool's dream, so he has to find another way.

What air weapons are the most practical in the current industrial conditions?

Incendiary bombs.

As long as the fuel oil can be refined, the Molotov cocktail mixed with white sugar, asphalt and aluminum powder, etc., can burn a city to the ground. With the current level of firefighting in the city, it is very difficult to fight fires.

It is very easy to refine fuel, as long as you find crude oil and distill it through the characteristics of different boiling points, you can get gasoline and diesel, and gasoline is enough.

Looking up the information of the City Lord's Mansion, I finally found that there was a desert four hundred kilometers northeast of Motie City, and there was a black liquid gushing out of the ground all year round, which was pungent and unpleasant, viscous and flammable.

Luo Qiu hurriedly took people, rode on the pedal three jumpers, and flew here, for safety, he also brought Gray and two undead saints to escort.

The Undead Sage doesn't weigh much, so he doesn't need to occupy a place, and he can just stay with Gray on a delta wing. With the three of them here, as long as they don't run into the dragon, their flying team will not fall to the ground.

Twenty silver skeletons were also present.

These silver skeletons are all transformed, and Luo Skull has made a hard-won defensive paint, and has given priority to spraying a layer of these twenty silver skeletons, so the surface of these skeletons is no longer shiny silver, but smooth matte black, and the defense power has skyrocketed.

Luo Qiu has experimented, and the silver skeleton sprayed with defensive paint has a defense comparable to that of a golden skeleton, and its defense against blunt weapons has skyrocketed.

In addition, the joint positions such as knees, ankles, and elbows are all reinforced with spring steel, and the collision of huge forces will not easily dislocate.

A team armed to the teeth flew silently to the shore in the night.

......

And on the coast of the coast, something that I don't know if it's a sampan or a sleigh is jolting in the waves.

The succubus maid sat in the front seat, her wrapped tightly in a special tarpaulin, revealing only one head.

A wave hit, and the front end of the sleigh was violently lifted high, and it fell heavily, making the sea splash everywhere, and the succubus couldn't hold back any longer, and lifted the mask and spit out a bunch of liquid.

That's how she vomited all the way, she had already vomited up bile, and her little face under her visor was as pale as a dead person.

The big witch in the back seat was cloaked, and the sea water slapped her face from time to time, making her wet like a ghost.

But as a lich, she was not affected in the slightest, her feet kept stepping under her seat, and the sleigh cleaved the waves at a speed not inferior to that of a sailboat, all the way south.

With the help of waterways, it took less than five days for her to travel from the far north to the south.

She looked up and estimated the distance, then looked at the state of the succubus, frowned silently, and adjusted her direction to step on the shore.

The succubus is a stepping stone to meet the King of Steel Bones this time, but don't die before you get there.

The sled rushed onto the beach and immediately flipped out four wheels, and before the wheels sank into the sand, the sled made a magical ripple that made the whole sled light.

Keeping it in its knees, the wheels spun and pushed the sled up from the sand to solid ground.

The sleigh stopped, and the succubus couldn't wait to pull the tarpaulin off his body, rolled over and rolled straight off the sleigh, not even caring about his demeanor.

The Great Witch ignored her and looked at the surrounding situation.

It's an unremarkable beach, and beaches like this are all over the coastline, and there's nothing worth paying attention to, and the witch retracts his gaze.

After half an hour's rest, the succubus regained some strength, and she turned to the witch and begged, "Oh Wu, shall we rest here for the night? ”

The succubus has been trained to be very obedient over the years, and she won't speak until she really can't stand it.

Realizing that the succubus was really at its limit, the Great Witch nodded and said, "Rest for the night." ”

After speaking, he didn't care about the succubus, turned down the board in front of him, put together a small table, and then took out a few gadgets and fiddled with them.

The succubus was pardoned, and quickly tore off the tarpaulin in the front seat and spread it on the ground, and fell asleep in a few breaths. She hadn't slept well on the sleigh, she was in a half-asleep state, even with the strength of her succubus, she couldn't bear it.

It didn't take long for Dawu to suddenly sense some movement, and hurriedly turned out a hollow circle from his hand and put it around his neck, turning his head to look at the sea.
