About 9,000 years ago, a carpenter surnamed Yan was compassionate to the hard work of the farmers, and he made simple tools that could quickly harvest crops, which is considered to be the origin of mechanical arts.

In order to commemorate him, later generations called these techniques Yanshu. Those who can flexibly use Yanshu are called Yanshi. Historians even set the year when Yanshu first appeared as the first year of the Tianyan calendar.

After more than 300 years, armor and armor made of gold, stone, iron and wood appeared on the battlefield for the first time, greatly reducing the casualties of soldiers.

However, in order to deal with these armor and armor, the more lethal and lethal weapons came into being, and immediately played a huge role in determining the outcome of the battle.

These offensive and defensive tools with good performance are collectively referred to as Yanjia.

For thousands of years, the battlefield became a breeding ground for the continuous improvement and evolution of the Yan. From the simple hand-held mechanical weapons, to the self-propelled chariots that can carry people on the march, and even to the later Yanjia people with sophisticated internal structures, good combat power and fearless death, all of them affected the outcome of the war at that time.

The flesh-and-blood soldiers gradually faded out of the main stage of the battlefield and turned into a logistics organization serving the Yanjia. The contest between the forces has almost become a simple competition for the performance and production capacity of various countries. It was at this time that the mainland was officially renamed the Tianyan Continent.

And Laoguan Mountain is just an inconspicuous one of the mountains stretching on the northern border of the mainland. It's still a shame that there is a border town called Laoguan Town at the foot of the mountain, so it got a name.

Halfway up the Laoguan Mountain, there is a simple farmhouse courtyard. This is where Ning Le and Mo Tao have lived in seclusion for nearly twenty years.

At this moment, the door to the main hall of the courtyard has been opened. On the side of the door, Ning Le, who had carefully poked out half of his head, was secretly looking into the hall.

In the main hall, there is an atmospheric and simple stone case, and there is a sacrificial shrine on the case, on which there are two tablets. The door of the stone cabinet under the stone case has been opened at this moment, and the wooden strips and steel pieces and other parts inside it are scattered, but there is nothing else.

Mo Tao, who was standing next to the cabinet, was full of color and brilliance at the moment.

Ning Le was a little weak-hearted, and carefully observed Mo Tao for a while, and then he had the courage to pretend to be arrogant and shouted: "I said that Lao Mo, what about you, don't you borrow a little bit of your private money, and the young master will pay you back in the future." ”

"Is it a matter of money?"

Mo Tao pointed to the pile of parts, and his voice was a little out of tune: "My little ancestor, the old man is asking you to unlock it, not to unbreak the lock!"

"The effect is almost the same!" Ning Le waved his hand and said, "Won't it be enough for your old man to spell it back again?"

"Why don't you put it back on your own?"

Mo Tao really couldn't help but reward him with a violent shudder: "How many times has the old man told you, although this magnetic array heaven attraction technique has been continuously improved by the old man for more than 20 years, it is incomparably powerful, but after all, it is still an immature skill, and the difficulty of control has a high risk factor, so don't use it if you don't fight for your life." It's good that you took such a big risk just to blow up the magnetic traction core in a lock cylinder!"

"Wealth and danger are begging. Ning Le muttered, "Besides, isn't there nothing wrong with this......"

Mo Tao glared at him: "This time you are lucky, there was no explosion when the core was destroyed, otherwise you would have to lie down for at least three or five months! ”

"Isn't that an exaggeration?

Ning Le smacked his tongue with palpitations, and said with a flattering smile: "Your old man will dissipate his anger first." Go back and wait for the master to master the production method of the Thousand Illusion Lock, and make a new one to compensate you!"

Mo Tao smiled coldly: "Okay, I hope you can still smile after reading the list of raw materials and production drawings." ”

Ning Le was stunned: "What do you mean?"

"Hmph. Mo Tao glanced at him, but finally gave up, shook his head and sighed, "I knew that you were a restless character, but I still couldn't resist it, and I taught you this skill, but now I think it's the old man's fault." ”

"Hey, it's something you've spent half your life developing. If you don't teach it to the master, are you willing to bring it into the coffin and let such a powerful skill be lost?"

Ning Le patted Mo Tao on the shoulder: "Don't worry, the young master of the magnetic array to attract the sky has more or less comprehended it, and when he uses it, he sacrifices part of his power, and it is not so easy to hurt himself." You just wait for us to completely perfect it and carry it forward. ”

"You'd better eat up the existing research results before you talk big. ”

Mo Tao pouted at him: "But then again, the optimization and improvement of this magnetic array Heaven Attracting Technique has encountered a bottleneck, and there must be a key point that the old man has overlooked." But what is it......

"Thinking about it slowly, this kind of thing can't be rushed. Maybe one day you'll be inspired by something, and the problem will be solved?"

Ning Le pillowed his arms and said slowly: "Moreover, the magnetic array leads the sky from the outside to the inside, and it hurts the whole from the inside, the threshold for exertion is low, the growth is excellent, and the external defense is ignored, and the power is huge." To be able to do this kind of is already a super-first-class level. This kind of trick is more difficult and risky to perform, although it is a flaw, it is also reasonable, right?"

"Hey, but the old man is not satisfied!"

Mo Tao smiled proudly: "What the old man is pursuing is the ultimate of Yandao. Only those mediocre talents will be a little better than others, and they will begin to be complacent and enterprising. ”

Ning Le agreed with what Mo Tao said in his heart, but he asked: "What kind of realm is the so-called Yandao Extreme?

When Mo Tao heard this, a look of remembrance suddenly appeared in his eyes: "...... Once, the entire continent thought that the Heartless City Lord was the ultimate of Yandao. Although he himself denied it, we only said that he was humble. But later I found out that, as he said, it was just the ultimate in our cognition...... However, even that kind of realm is definitely not something that anyone else on the continent can look up to. ”

Ning Le couldn't help but smack his tongue.

In his mind, Mo Tao's Yanshu can only be described in four words: unfathomable. And Mo Tao himself is also extremely proud of his martial arts.

For him to say this, how terrifying is this so-called "epistemic extreme"?

Heartless City Lord, the master of the Yandao Holy City that once stood in the center of the Tianyan Continent, the Heart of the Heavenly Yan......

Even today, twenty years after his fall and the Holy City has long since been reduced to ruins in the catastrophe of destruction, this name is still a legend in everyone's hearts.

It's a pity that such a peerless Yanshi who has never been seen before or after him has no chance to see his heroic appearance with his own eyes.

"Hone yourself. ”

Seeing the look of longing in Ning Le's eyes, Mo Tao rubbed his head twice, and sighed with a smile: "The road is long and the line is coming." ”
