In this speed competition, Zhou Ming finally took a "faint" advantage, leading by about 0.1 seconds, and stood on the top floor of the medicine bottle castle.

Princess Syvanis and Nabe then arrived.

Because they didn't slow down at all, they stepped on the castle wall, climbed vertically for more than 20 meters, and stood in front of Zhou Ming.

On the hard city wall, there are footprints of two strings of iron boots.

"Are you really an intermediate mage?" Princess Shivines asked, how can an intermediate mage fly so fast?

"You bastard, let's do it again!" Nabe gritted her teeth, unwilling to lose the game.

"I'm the smartest mage, much faster than ordinary mages, of course. ”

Zhou Ming said lightly, in fact, in order to take care of their face, he deliberately slowed down a little later, otherwise his lead would be at least more than 2 seconds.

With that, he walked downstairs.

"Rub~"

Nabe drew half of her sword and said in a cold voice, "Don't go, let's compete again!"

"Next time, I don't have much magic in me. ”

"Hmph~ I will never lose to you next time!" Nabe reluctantly put away her sword.

Princess Syvanis smiled and shook her head.

……

There are two more people in the medicine bottle castle, and it is suddenly a lot more lively.

In addition to being boring and boring, Zhou Ming also has two more objects to tease.

Princess Severis is relatively quiet, has a smart and rational mind, loves to read, loves to think, and often asks Zhou Ming to discuss some in-depth questions.

The guard Nabe has a hot temper, bitter words, and a strong personality, and her feelings and bonds for Princess Xiwenis always make Zhou Ming can't help but think about it.

Such a pair has entered Zhou Ming's life, and daily quarrels and quarrels must be indispensable.

Zhou Ming felt that the most interesting thing was: every time he discussed some lofty topics with Princess Syvanis, he often secretly admired Nabei on the side, and he thought it was too funny with a "jealous" expression.

It's just that every time she competes in martial arts, Nabei's performance of sparing no hands and going all out, as if she is going to split him alive, has improved Zhou Ming's actual combat skills a lot...... So that he could retreat unscathed under the fierce attack of a great swordsman-level fighting powerhouse.

In short, Zhou Ming felt that it felt good to have two such guards around him.

For the next two months.

Zhou Ming has done all the things.

Dilo Bank was established, successfully completed the financing of 30 million gold coins, and immediately became the only and largest bank in the Kingdom of Adud, with 20 branches in China and 22 chain branches abroad, and on the day of its official opening, it attracted 100,000 people to deposit money due to the high interest rate of 3.5% per year on deposits.

In addition, in terms of banknotes, Zhou Ming has set up a technical research and development team, which is undergoing research and development of banknotes, and it is expected that in about half a year to a year, banknotes with high anti-counterfeiting functions can be officially launched.

Secondly, on the side of the potion production plant, Zhou Ming organized a wave of large-scale production, and all five potions were rolled off the production line, and a total of 100,000 bottles of magic potions were obtained, which could be sold for the second time.

And on the side of the old fox Roberts, under Zhou Ming's soft grinding and hard bubbles, as well as various threats, the old fox had to write him a letter of recommendation, recommending him to go to Gray School of Witchcraft and Wizardry for exchange and study, and the exchange time was 3 months.

Coupled with the time spent on the road, Zhou Ming was given a total of 6 months.

And they will send a teacher to follow him, for fear that he will never return or will not return for a long time.

I'm afraid that some people here will say that the old fox is too unreasonable, three months, what can he do in just three months? It has passed in the blink of an eye, and many actions cannot be performed at all.

He's going to have to help save people.

Three months, most likely, is not enough.

However, for Zhou Ming, he felt that it was almost enough.

Because he actually has 6 months.

He has a way to shorten the 3 months that need to be spent on the road to 3 to 5 days, and the more than 50 days saved can also be included in the "effective time".

Saving more than fifty days, how did he do it?

Magic planes.

He built a magic plane.

……

Continental Chamber of Commerce.

In the technical laboratory, which has only been established for less than three months, several magicians are conducting various tests around a strangely shaped device.

The strange device is shaped like a pumpkin, with a flat ellipsoidal shape and a silver-white metal shell, and the exterior is painted with circles of lines, criss-crossing and full of geometric beauty.

These are the mana patterns, which are used to deliver mana.

This strange device is called the "Wind Demon Engine".

Powered by wind magic.

"Start typing the mana. A white-bearded old man in the lead said.

"Yes, enter mana!" a mage heard this, and immediately put his hand on the fist-sized philosopher's stone and injected mana inside.

The magic lines on the surface of the Wind Demon engine soon emitted a white glow, indicating that the magic power had entered the engine.

"Buzz~Buzz~"

"Buzz~"

The Wind Demon engine began to spin faster, faster and faster.

"Boom~Boom~"

The metal blades in the engine emitted a burst of roaring sounds, indicating that the speed of the local blades had exceeded the speed of sound, so a sonic boom was generated.

"Report thrust data!"

"1100 shield power (1 shield force ≈ 1 kg)...... 1150 Shield...... 1200 Shield......"

"Keep ramping up the power!"

"Boom, boom~" The magician increased the mana input.

On the test bench, the pumpkin-sized Wind Demon engine emitted an even more violent roar.

"1250 shield power...... 1280 Shield ...... 1320 Shield ...... I can't go any further, and my mana input has reached its limit. ”

"There are small cracks on the surface of the engine, and the power can not be increased anymore, the engine will explode!" said another anxiously.

"Reduce the mana input and stop the experiment. The white-bearded old man said.

"Click~" When the engine stopped, there was a grinding sound.

Obviously, after this extreme test, this wind demon engine has reached the verge of scrapping.

The white-bearded old man Modov didn't feel much pity, but looked happy.

Holding the "Wind Demon Engine", which weighed only ten kilograms, his eyes flashed with admiration.

"What a simple principle," Maudoff muttered, "why haven't I discovered it in my life, but I've been thinking about how to increase the griffon's load-carrying capacity?"

"What an amazing magic, I didn't realize until now that you are so magical. ”

Modov's eyes flashed with regret, regret that he had only discovered the truth until now, and that he had found that most of his youth had been consumed in meaningless things, and that the magic that had been taken for granted was now discovering its magic.

"Squeak~" sound.

The door to the lab was pushed open.

Zhou Ming strode in, and when he saw Modoff, he asked: "Old Mo, how is the pumpkin 1 wind demon engine tested, has the thrust exceeded 1000?"

Zhou Ming hasn't been here for more than ten days, and the last time he came, the maximum thrust of the Pumpkin 1 Wind Demon engine was only 950 shield power, and it hadn't reached four digits.

"Breakthrough, breakthrough!"

"You're just here, it's 1,320 shields! This is the highest stat we've gotten so far. ”

Modoff said with a bright face, to be honest, at the beginning, when this kid Leylin held a stack of blueprints, and said that according to the magic engine designed on this drawing, the power generated by one was the sum of the strength of ten griffins, and he thought that this kid was either crazy or insane.

Now it seems that this kid is a genius!

"1320 shield power. ”

Zhou Ming groaned for a moment and nodded: "With a thrust-to-weight ratio of more than 130 and a power that reaches the standard, this engine can be finalized and installed on the aircraft I designed." ”

Hearing the word 'airplane', Modov's eyes lit up and he nodded again and again: "Okay!"

The monoplane designed by Zhou Ming is similar to the first jet fighter jet in the modern world, with a round metal fuselage, triangular wings, vertical tails, and flaps that control flight attitude...... The two are almost alike.

But the difference is that Zhou Ming uses a thrust-to-weight ratio of more than 100 Wind Demon engine, small and lightweight, no fuel device, the fuselage is made of low-density and high-strength aluminum-like alloy materials, 3.8 meters in length, empty weight of less than 600 kg, there are 3 seats in the cockpit, up to 3 passengers.

As for the maximum speed, it can exceed the speed of sound.

At an economic speed of Mach 0.8, 100,000 miles can be reached in more than two days.

And this speed is 10 times faster than that of a griffin!

This is also the reason why Zhou Ming asked the old fox for leave, and the other party gave him three months, and he readily agreed.

"Lei Lin, the thrust of the Wind Demon engine is so strong, if we study the Fire Demon engine based on fire magic, can we make the thrust of the engine greater and the thrust-to-weight ratio higher?"

Modorf has expanded, and the potential of his Fire Demon engine will not be smaller than that of the Wind Demon engine!

"Theoretically, the maximum power density of the fire demon engine can reach 2.5 times that of the wind demon engine, but the material of the engine is difficult to withstand the high temperature of more than 3000 degrees, after the blade speed breaks through 3 times the speed of sound, the material bearing capacity reaches the limit, and the increased air resistance will also affect the efficiency of the engine. ”

"Until the material problem is solved, the Wind Demon engine is the best magic drive device at present. ”

Zhou Ming explained to him.

Modoff nodded: "I know, wait until I perfect the Wind Demon Engine first, and then study the Fire Demon Engine." ”

Zhou Ming asked again: "By the way, Lao Mo, how is the research on the oil-fired propeller engine that I asked you to study? Has the diesel oil in the oil been separated? Has the problem of engine ignition been solved? This kind of engine is of great significance, and if it is successfully developed, even ordinary people can operate the aircraft for air transportation, saving a lot of transportation costs." ”

"Oil-burning propeller engines?"

Modolf looked uninterested: "That thing is too troublesome to get it, the kind of oil you said is the blood of the devil, the dirtiest thing in the world, many people don't want to touch it, we have separated some of the diesel, and the ignition problem has been solved, but it is not very easy to use, the engine is easy to emit black smoke, and it will overheat after burning for a while, not as good as the wind demon engine." ”

"Of course it's not as good as the Wind Demon Engine, but the Wind Demon Engine can only be used by magicians, if you can solve all the problems of the propeller engine, believe me, the application range of this thing is more than a thousand times that of the Wind Demon Engine, and the griffins raised by the entire continental general Chamber of Commerce will be replaced by planes equipped with this engine. ”

Zhou Ming said that the probability of the birth of a magician is one in a million, and the vast majority of people in this world belong to ordinary people, and in order to win more than 99.9% of the ordinary market, a diesel-based propeller engine must be developed.

"Well, I'll put some thought into that. ”

Modov nodded, and now in the Continental Chamber of Commerce, Lei Lin, who took out the Wind Demon engine technology, has received great attention from the high-level, and the high-level has decided: Once the Wind Demon engine technology is mature and has been applied on a large scale, he will be given 10% of the shares in the magic transport aircraft in the future.

Zhou Ming, who has 10% of the shares, doesn't particularly care about it, he hopes to push the mainland general chamber of commerce to let the other party develop in a promising direction according to his own plans and assumptions.

Of course, there will be many difficulties at the beginning, but after all the problems are solved, the interests of Tianliang are placed in front of the mainland general chamber of commerce, and the other party will definitely change its concept, increase investment, implement a thorough transformation, and become a giant transportation chamber of commerce.

In the future, this giant chamber of commerce will definitely be able to bring great convenience and help to Zhou Ming.

……

Three days later.

A jet with a 'Pumpkin 1' Wind Demon engine installed behind the butt was placed in front of Zhou Ming.

Tornado 1.

Zhou Ming casually named the plane.

I opened the glass cockpit and sat inside, placing my right hand on the magic stone at the top of the joystick, and slowly injecting mana into it.

On the long dirt and rocky runway, Hurricane 1 slowly accelerated.

Under the astonished gaze of Princess Sylvanis and her guard Nabe, who were sitting in the back seat, the speed became faster and faster, and under the principle of buoyancy, they got rid of gravity and soared into the sky.
