Master Mark appears to be a half-bald Caucasian man, about fifty years old, tall and thin, wearing a pair of half-rimmed square glasses, which gives a somewhat old-fashioned first impression.

"Master Mark, I have admired you for a long time, and I have read your published "Starting from Scratch, Mastering the Wind in Thirty Days" several times."

Ye Chenxi's face was not red, and he said without a beat.

In fact, he only flipped through this book cursoryly, and when he checked Qiandu yesterday, he suddenly found that this master of the flight department had published a lot of books, so he hurriedly read it overnight.

"Really?"

Mark replied in English in surprise.

He didn't expect that the book he wrote would be so popular, and he had his own young readers in China.

"Well, it helps a lot with the training of the sonic dragon."

Ye Chenxi continued without changing his face:

"Almost every one of my classmates has one."

“ohmygod！”

Master Mark's expression gradually became exaggerated, and the books he published were unpopular in the United States, but he did not expect them to sell well in China beyond the ocean.

"I didn't expect to see you here, I can ask you some questions about elf training."

Ye Chenxi's attitude was sincere.

"No problem! Have a thrilling elf showdown? ”

Master Mark readily agreed, and even offered to ask for a fight.

"Whew~"

The sound wave dragon beside Ye Chenxi took the initiative to respond, his eyes were scorching, and he was full of strong battle intent.

"My sonic dragon said...... It wants to fight your sonic dragon, is that okay? ”

"No problem."

Master Mark throws a Poké Ball forward, and another sonic dragon appears in midair.

"It's called supersonic because it's so fast!"

In terms of size, the supersound was a circle larger than Ye Chenxi's sonic dragon, and the red claws were not as bright as the sonic dragon, but a little dull.

The white fluff on the neck is not as lush as the sonic dragon, and it is a little sparse, which may be due to age.

Of course, it is also possible that there is a genetic problem, just like its owner.

The white fluff around the neck of the sonic dragon is like a scarf, and Ye Chenxi can put his hand into it when he sits on its back and flies, which is warm and super comfortable.

——————————————

Battle on the beach.

Ye Chenxi and Master Mark stood on both sides of the beach, and in front of them were sonic dragons with huge spiral ears and purple-black bat wings.

It is the season of spring and summer, the temperature has not yet risen, and the breeze blows, bringing a little coolness, but its heart is particularly hot.

Is this the opponent in his own destiny?

"You attack first!"

Master Mark said calmly.

This is a battle with a huge disparity in strength, so he limits the upper limit of the energy level that his sonic dragon can use, the elite primary.

"Ride the wind!"

Ye Chenxi was not polite, and in a moment, the sonic dragon had already waved its bat wings, and the direction of the surrounding air flow quickly changed, blowing violently in the direction of the opposite supersound.

Above the elite level, the key to the battle of flying elves is the control of the field and the control of the airflow!

And the tailwind of the sonic dragon is the headwind of the supersound.

"The understanding of air flow is very good, and this wind control ability has reached the level of a gym-level elf."

Master Mark nodded in affirmation, hard to believe that the other side was just a high school student.

This level is difficult for even the elves of elite students to reach in their country!

Are the trainers of Huaguo terrifying?

"We also use tailwinds."

Master Mark came back to his senses from the amazement and spoke calmly.

As soon as the words fell, the supersound quickly flapped its wings, and the wind gusted, and the air flow around it suddenly became disordered, and it actually formed a circular wind field!

If the tailwind of the sonic dragon is relatively mild, then the tailwind of the supersound is absolutely domineering!

The wind speed in this field has reached a terrifying level, and the air flow is almost in substance!

"The rhythm of the wind!"

The sonic dragon blends into the surrounding wind and becomes more sensitive to air currents, bursting with unparalleled speed in an instant.

The purple figure swirled the air current, like a sharp sword piercing into the field of supersound's wind.

Entering the field of supersound's wind, the sound wave dragon felt that he was stuck in a deep quagmire, and the high-speed twisting wind around him was preventing it from moving forward, and a cramped feeling came from all over his body, and the telepathic Ye Chenxi felt the same way.

"Reverse scales!"

"Roar!"

With a roar, the sonic dragon had already entered a state of "violent blood".

This bloodline awakening move can burst into powerful power in an instant, but it also comes with severe side effects.

Loss of mind, physical exertion.

After a long period of training, the sonic dragon has been able to maintain its sanity in a state of reverse scale.

Wind Hunting, the dragon blood in the Sonic Dragon's body boiled, and its speed increased again, instantly breaking through the suppression of the Wind Domain.

Immediately afterward, a white light lit up on the Sonic Dragon's teeth, which instantly became extremely hard, and bit down fiercely at the supersound.

"Bang~"

It missed, and all it bit was an afterimage.

The speed of ultrasound is just as fast!

Not only is it not affected by the high wind pressure in the wind field, but it is like a fish in water.

The sonic dragon's golden eyes flickered, like burning gold, and the bat's wings flickered, and it rushed out again.

This time, the supersonic made a swallow return.

At the moment of dodging the attack, he attacked from an uncanny angle.

The sonic dragon dodged with a keen sense of air currents......

It's purely a battle between speed and speed!

The two sonic dragons flew at high speed, and it was impossible for the naked eye to catch them.

Ye Chenxi relied on telepathy and strong spiritual power to barely keep up with this rhythm.

In such supersonic combat, ranged moves have lost their meaning.

Before the energy began to condense, the position of the other party had already changed dramatically.

Dragon's Wave and Sonic Wave are completely useless.

......

Half an hour later, Ye Chenxi returned to his apartment.

In the battle just now, Sonic Dragon lost the game without accident even though he used all his strength.

As soon as the reverse scale state ends, it means the end of the battle.

Although the opponent has limited the energy level, his physical fitness, understanding of air currents, and combat quality are much higher than it.

It is very likely that this level of combat is the result of the opponent's deliberate feeding moves.

Angry Incisors, Reverse Scales, Swallow Returns, Air Blades, Shadow Clones, Tailwind......

The moves of the Sonic Dragon Club are opposite, and the moves that the Sonic Dragon will not have...... The opposite side will too.

The most important thing is the realm of the wind.

High-end use of downwind moves.

In this realm, Sonic felt that he had been deprived of a lot of control over the air currents.

It is equivalent to fighting completely on the opponent's home field.

"Whew!"

The sonic dragon was still a little unsatisfied, and let out an excited roar, it had not been in such a hearty battle for a long time.

That's what it is...... What does it feel like to be in battle with a fateful enemy?

Although I lost, I was still looking forward to the next match.

"I always feel ...... Ultrasound is not your mortal enemy, but it is just divination in the first place, so you don't have to take it seriously, take it as your goal, and keep motivating yourself It's not bad. ”

Ye Chenxi said a word, and then continued to think about the Wind Realm that Master Mark had said.

After the battle, Ye Chenxi naturally asked the other party for advice on the skills of using the Wind Domain.

Master Mark also gladly answered, after all, he was his own young reader in China.

"Bringing the wind speed in an area to an extremely high level of wind pressure creates a zone of high wind pressure that changes the airflow from invisible to tangible......"

"It's important to note that...... The wind speed in the high-pressure band needs to be kept constant ......"

Seem...... Isn't it a very difficult look?
