"Air is omnipresent, and all human actions will lead to the flow of air, such as running, punching, and swording. In addition, when the source force is emitted, it is also a kind of air flow, and in general, the movement of all objects will produce air flow, but some are strong and some are weak".

"The Doctor's air flu should be metal, literally, a metal that senses air currents, right?" said Roger.

"To be exact, the metal that can sense and react quickly is a new liquid metal pellet, as long as you eat it, it will become countless iron elements distributed in the body, and it usually has no effect on the human body, but when you are attacked, the iron element will sense the air flow and quickly gather in the place where the air flow is strong to solidify the part of your body that is being attacked, making that part harder than steel",

"Well, isn't it a subversive concept?", Demley looked at him triumphantly.

Roger nodded in thought, this was a subversive concept, and it sounded like something impossible to make.

"Doctor, is the so-called liquid metal pellet permanent or temporary?",

If you have to eat a metal pellet every day, it will be a bit troublesome.

Demley said: "Of course it is permanent, eat one and take effect forever",

"If a person is running after eating a metal pellet, and the air flow outside the body is always violent, will it still react?" asked Roger.

Demley said: "Little ghost, I forgot to mention an important design concept, that is, the difference in induction airflow, if there is no core metal pill, it will be in an uncontrollable state",

"Poor airflow, haha, doctor, that's wonderful", before he finished speaking, Roger excitedly slapped the table and stood up: "Sensing the difference in airflow, then in addition to the opponent's attack, you can also use the source force to create a powerful airflow to gather iron elements to achieve the purpose of partial solidification, hahaha, doctor, you are simply a genius",

Demley, who wanted to show off, opened his mouth and looked at him for a long time and took a bite of the sauce duck in frustration, this little ghost understood it too quickly, and he, who was in charge of explaining, had no sense of accomplishment at all.

Roger excitedly walked around the room, if this metal pellet was made, it would definitely be the most perfect armor in the world. It doesn't have any weight but has absolute defense.,It doesn't have any effect on its puppetry.,If you eat such a metal pellet, you can only attack and not defend when fighting.。

"Doctor, is one month enough to complete the liquid metal pellet",

"Forehead cough",

Demley, who was eating the sauce duck, was choked up, and looked at Roger angrily and said: "Little ghost, don't dream, don't talk about a month, if you can do it within ten years, just laugh."

"Ten years",

Roger sat down a little dejected, but thought about it. The so-called metal pills still only exist in theory, and even a bit like a fantasy, and whether it is the idea of the idea or the person who really sets out to do it, there is only one doctor, financial and material resources are not lacking, but manpower is really stretched.

Roger and Demley had been exchanging ideas about the liquid metal pellet for a long time, and in a sense Roger was his old friend, there were too few people on the continent who could communicate with the Doctor, and in Corloga, Roger was one of the few in the small town of Slok.

"Doctor, we're back and bought you something delicious", it was already dark, and there was a knock on the door, and it was Lolita's sweet voice.

Roger hurriedly trotted over and opened the door.

"Ah, Master Roger is also there", Lolita was obviously a little surprised.

Leo at the door was carrying a large bag of things, and Lolita was carrying a box of cakes and placing it on the doctor's table.

Roger smiled: "Miss Lolita, I have already booked a private room at the Bligh Hotel, and the time is almost up."

Lolita said with her hands behind her back: "Oh, Doctor, Uncle Leo, let's go together, I heard that the Bligh Hotel is the best hotel here",

"Ah, ahem, Dr. Ahem, I've already eaten, Uncle Leo, he still has to exercise his abdominal muscles and biceps at night, I'm afraid he won't be able to go",

"How so, the Doctor had already promised me at noon," Lolita looked at him slyly.

Demley glanced at him and said, "Stinky little ghost, can the sauce duck compare to the feast of the Bligh Hotel?

"Don't, if the doctor doesn't go, Lolita and I, how can Uncle Leo eat with peace of mind?

Demley nodded in satisfaction: "Seeing that you are so sincere, I will reluctantly agree to you", he lit his pipe and walked out of the house, and Lolita stuck out her tongue at him and bounced and trotted out.

Roger loves her and hates her, when did this little girl become so cunning, when he walked out of the Swan Lake Hotel, his stomach was spinning, and today he had to find a way to let Lolita know how powerful he was.

"Stampede",

"Drive, drive". ，

At this time, it was already dark, but a group of cavalry suddenly appeared in Slok Town, and the horse-hoofed cavalry rolled up a billowing cloud of smoke and dust into Slok Town, and the streets immediately resounded with exclamations and curses. The cavalry, less than twenty men, appeared in the streets of Slok Town with great arrogance, and in a matter of moments many were knocked over on their backs.

"Hell, where did you come from, wild bastards",

"Sneer",

Before the people could react, they saw an extremely tragic scene, a man just shouted and cursed when he was poked in the head by the heavy cavalry gun in the hand of the cavalry leader, and he fell down without even snorting; then there was a burst of screams, the people on the street screamed and scattered in all directions, and the cavalry that was so strong that it continued to rush forward without stopping, and those who could not dodge were immediately knocked over on their backs, wounded, wailing, and fleeing, as long as they blocked the way of the cavalry, they were immediately shot to death by the black-armored cavalry led by the leader.

As soon as Roger and the others walked out of the Swan Lake Hotel, they saw this tragic scene, and Lolita, who saw this bloody scene for the first time, turned pale.

"Lolita, come back quickly", he grabbed Lolita's hand with one hand and covered her mouth with the other and retreated to the hotel, and Demle and Leo quickly retreated.

The long street soon fell silent, and the cavalry rushed laterally and left only thirty or so corpses without looking back, and behind them were the streets covered in blood and the people who were dodging in terror in all directions.

Roger hid behind the door of the hotel only glanced at the black heavy cavalry led by him, his body was twice as large as the average person, and he carried a heavy sword nearly a man tall behind him. The mount was a big black horse, larger than the average horse, and he sat on the horse a head taller than the cavalry behind him, and he exuded a hideous aura all over his body, and just a glance at Roger saw his face under the steel helmet.

He was grinning.
