However, no one saw a trace of arrogance on Wu Meiniang's face behind Merton, and she jumped out and said: "Uncle Shi wants to compete with the master, then I'm afraid he has to pass the pass of Mei Niang first." ”

Li Yun and Gong Yihong couldn't help but be stunned, no one thought that at this time, Wu Meiniang would come forward and take the initiative to come forward for the Mo family.

"Could it be .................."

The two glanced at each other, and a possibility flashed in the eyes of both that they had never imagined.

"Could it be that even the female apprentices of the Mo family have solved this problem."

Li Yun couldn't help but hold the folding ruler on his cuffs tightly, and couldn't help but sigh in his heart, in his opinion, the ruler that could meet the conditions of the Mo family was the folding ruler in his palm, and there was no other way, if he and Wu Meiniang had the same idea, then I am afraid that he could only have a tie with the apprentice of the Mo family, so that although he was flat, he was still defeated!

And Gong Yihong was even more unbelievable, he never thought that the problem that would stump the entire public loser would be solved even by a girl who was more than ten years old.

Wu Meiniang proudly turned around and saluted Merton: "Master Qiqi, ten days ago, the master left homework for the apprentice on this bridge, and today the apprentice has been completed, and I ask the master for guidance." ”

After Wu Meiniang found a way to make a tape measure, she didn't immediately report to Merton, she just wanted to prove herself to Merton on the spot at this moment, but she didn't expect such twists and turns.

Morton glanced at Wu Meiniang, the news about Wu Meiniang's completion of schoolwork had naturally reached his ears, and then looked at Li Yun and Gong Yihong, showing an inexplicable smile and said: "The inferior has just entered the Mo family, and he is not good at learning, if there is anything inconsiderate, please don't laugh." ”

Gong Yihong suddenly snorted and said: "Although the apprentice is young, the reputation of the senior sister of the Mo family has already spread all over Chang'an City, and the silver mirror made by her sells well in the Tang Dynasty. ”

A trace of contempt flashed in Li Yun's heart, if Wu Meiniang made a folding ruler, he would consider himself unlucky, if not, the Mo family dared to cheat against his will, then don't blame him for being ruthless.

Wu Meiniang walked in front of Li Yun, took out a palm-sized item from her ink pocket, Li Yun unconsciously touched the folding ruler of his cuffs, although he didn't like the Mo family, but I have to say that the pocket design of the ink suit is extremely convenient, which is quite in line with the concept of the Mo family's economy.

"Since Uncle Shi also made a ruler, how about you and I show it at the same time?" Wu Meiniang opened her eyes wide and looked at Li Yundao innocently.

Li Yun couldn't help twitching the corners of his mouth, Wu Meiniang's move was extremely cunning, if others didn't know, they thought he was competing with a teenage girl?

"Don't be rude!" Merton scolded.

"Uncle Shi, Mei Niang is ugly!" Wu Meiniang stuck out her tongue and took the lead in stretching out her palm, only to see that there was a palm-sized wooden box in the palm.

"One hand in control!" Li Yun's heart sank, this is the most difficult part of Mo Jiazi's schoolwork, Wu Meiniang's ruler is actually the size of a palm, and it is the size of a child's palm, in terms of size, it is already half of the success.

However, Wu Meiniang's ruler is round, so naturally it did not collide with his folding ruler, which made him breathe a sigh of relief and a little more solemn.

Subsequently, Wu Meiniang slowly pulled out a flat cloth ruler from the wooden box, which was covered with dense scales, and Wu Meiniang made a move behind her, and a child of the Mo family stepped forward to help, and the two worked together to slowly show everyone a cloth ruler as long as one zhang.

"Accurate to the fifth centimeter!"

"Cloth rulers can be rolled into rolls! Naturally, you can control a ruler with one hand. ”

Gong Yihong saw Wu Meiniang's cloth tape measure, and suddenly realized, the original difficulty about the tape measure in his heart was suddenly realized, but these two problems seem to be easily solved by Wu Meiniang, but for ordinary people, it is extremely difficult, because the cloth rope for making a cloth tape measure is extremely rare, and only Mojia Village has such a process.

After Wu Meiniang finished displaying, she pulled the small rocker on one side of the wooden box, and with Wu Meiniang's slight force, the one-zhang-long cloth ruler was slowly incorporated into the wooden box, and it was restored to a palm-sized wooden box again.

"How can it be?" Li Yun couldn't help but shrink his eyes, shocked by Wu Meiniang's whimsy, he originally thought that his folding ruler must be the only answer, but he didn't expect that Wu Meiniang would choose a completely different path.

"Mei Niang is waiting for Uncle Shi's master." Wu Meiniang is colorful.

This time, Li Yun no longer had the slightest contempt, but solemnly took out a half-foot-long three-finger-wide wooden block from his cuff and showed it in front of everyone.

"Wooden blocks!" Gong Yihong couldn't help frowning, how could this be a ruler, only Merton's eyes lit up, and he couldn't help but think of a ruler commonly used by carpenters in later generations.

I saw Li Yun's hand shake, the wooden blocks that were originally two fingers wide turned out to be a thin piece of wooden planks combined, under Li Yun's force, the wooden planks were connected by Mu Liu, and they actually formed a one-zhang long wooden ruler.

"Wonderful!" As the pinnacle of traditional carpentry, the public loser does not know how many generations of carpentry has been invaded together, so he naturally agrees with Li Yun's idea of folding the ruler.

And Wu Meiniang used a cloth ruler, while Li Yun used a pure wooden ruler. Naturally, it is more recognized by the public.

"The next is exactly the fifth centimeter." Li Yun nodded and said, he had a good understanding of this with Wu Meiniang, and at the same time thought of this idea.

"I'm afraid that's the limit?" Gong Yihong sighed, everyone in the world says that the difference is a thousand miles, but it is already difficult to divide, let alone a millimeter.

Li Yun's hand shook, and he saw that the original one-zhang long wooden ruler was randomly folded into sections and restored to the original one-foot-long, three-finger-wide wooden board.

"Uncle Gao is smart, and the little nephew is willing to bow down!" Wu Meiniang suddenly took the initiative to admit defeat.

Li Yun couldn't help but be stunned, he didn't expect Wu Meiniang to take the initiative to admit defeat, although he was very confident in his folding ruler, but Wu Meiniang's cloth tape measure was also extraordinary, and it was not necessarily better to win or lose than to really compare.

"Mohou really taught a good apprentice!" Gong Yihong said meaningfully.

Merton coughed and said: "Although Mei Niang has completed the ruler according to the regulations, there are many things that need to be improved, and it is cumbersome to make, while Brother Li's folding ruler is simple to make and ingenious, which is indeed slightly better." ”

Although his disciple lost to Li Yun, he was still honored, and Merton was naturally happy to give Li Yun a face.

"The cloth tape measure of the Lingtu seems to be extremely rare, and Mo Hou is too embarrassed junior!" General Gong Yihong said, Wu Meiniang's design even he couldn't help but be amazed, he didn't believe that Morton could point out any flaws under his words.

Merton laughed and said: "Brother Gong is too high-minded to look down on the inferior, although the cloth tape measure has advantages, but the cloth ruler is too soft, too short things can be operated by one person, if it exceeds the length of more than six feet, I am afraid that two people will have to cooperate." ”

Everyone couldn't help but think about it, when Wu Meiniang showed the cloth tape measure, she pulled a child of the Mo family to cooperate, which is indeed a shortcoming. Not only is it a disadvantage compared to a cloth tape measure, but this defect is almost negligible.

"However, there is an unparalleled advantage of the cloth ruler, that is, compared with the wooden ruler, the cloth ruler can be thinner, that is, under the same volume, the cloth tape measure can be fitted with a longer ruler." After Merton finished speaking, he pondered for a moment and said: "If this cloth tape measure is several times larger and the length is increased to fifty zhang, it will definitely have a more prominent effect, and the previous defects are enough to make up for it." ”

"Fifty zhang!" Gong Yihong couldn't help but feel a shock in his heart, and couldn't help but be amazed by Merton's idea. The distance of 50 zhang is enough to be 150 meters in later generations, in this era, long-distance measurement is very troublesome, if you use a cloth tape measure of 50 zhang, two people can easily and accurately measure, and it is easy to carry, free to retract, it will definitely be very popular.

"Teach in vain!" Wu Meiniang was convinced.

"Brother Mo is really extraordinary, how about pointing out Li's folding ruler?" Li Yun was a little unconvinced.

He originally thought that the cloth tape measure was on par with his folding ruler, but he didn't expect Mo Jiazi to point out the defects of the cloth tape measure and improve it in a few words, and it had overshadowed the limelight of the folding ruler all of a sudden.

Morton looked at the folding ruler in Li Yun's hand, and said with a smile: "Brother Li's folding ruler naturally does not have the defects of a cloth tape measure, it can be easily straightened, and the length within one zhang is under control. ”

Li Yun couldn't help but show a trace of smugness when he heard this, but before he could wait for him to be proud, he heard Merton's voice change and said, "But ......"

"But after all, the length of our arms is limited, and barely six feet is the limit, and the most suitable length for operation is three feet, which is why craftsmen use the most common three-foot wooden ruler. If the length of a single section of the ruler was reduced to three inches, the length was reduced to three feet, and the ten planks were only one finger thick, so that the craftsmen could easily handle and carry around, wouldn't it be very popular. ”

"Three inches long, one finger thick!" Li Yun thought thoughtfully, looked at the folding ruler in his self-help hand, and with a little force, he directly broke off a third.

Li Yun took the three-foot-long folding ruler and operated it back and forth with both hands, which was really much more convenient than the previous one-zhang-long folding ruler, and it could be held in the palm of his hand, which was extremely convenient.

"Li Yun has been taught!" This time, Li Yun bowed his head in convincing.

Gong Yihong couldn't help but be really embarrassed, he didn't expect Mo Jiazi to really make the folding ruler and cloth ruler shine in a few words, and couldn't help but say stupidly: "Today's old man is fortunate to be able to witness the good fortune of the craftsman together, now the cloth tape measure can easily measure long distances, and the folding ruler can easily measure the distance of three feet, the old man heard that Mo Hou Zeng said, he will also make a ruler and the disciples to compete together, I don't know if it can open the old man's eyes." ”

Li Yun's heart moved, now the ruler for short-distance and long-distance measurement has been determined, only the medium-distance ruler is still blank, if so, Mo Jiazi can perfectly solve the medium-distance ruler that measures the distance of one zhang, and the wooden ruler of Datang has been perfected.

"This is a game between Mo and the bad guys, I didn't expect it to alarm so many people and make you laugh." Merton smiled wryly.

Gong Yihong pressed step by step: "Although it is a game, it is enough to benefit the craftsmen of the world, Mo Hou can't be modest!" ”

Merton laughed, reached out and grabbed a palm-sized item from Mofu's pocket, stretched it out in front of everyone, and said solemnly: "It's ugly." ”

Everyone immediately looked at it, only to see that in the palm of Merton's hand, a white metal object appeared in the realization of everyone.

"It's iron!" Gong Yihong said uncertainly.

"Steel, to be exact!" Merton nodded and said, "This is the steel ruler made by Mo!" ”

"Steel ruler!" Everyone immediately looked at each other.

Li Yun made a folding ruler with wooden blocks, and Wu Meiniang made a cloth tape measure with a cloth rope, no one thought that the material used by Mo Jiazi turned out to be steel, I am afraid that there is no precedent in the world for using steel as a ruler.

"Steel can be made into a ruler!" Not only are others incredible, but even Wu Meiniang is incredible, you must know that steel is harder than wood, how can it be the size of a palm?

"Everyone knows that steel is extremely tough, but they don't know that steel is also extremely flexible, a thin sheet of steel can be bent and quickly restored once you let go," Merton explains. ”

Gong Yihong nodded solemnly, he often deals with steel, and he has a little more recognition of Mo Jiazi's steel ruler in his heart.

Therefore, Mo asked Mojia Village to specially refine a batch of steel with good flexibility and roll it into a thickness of about one centimeter. Cut into a finger-wide steel bar, engraved with the most precise scale, assisted by the secret skills of Mojia mechanics, and finally there is this masterpiece in front of us, the steel ruler. Merton said solemnly.

At this moment, almost everyone's eyes were fixed on the steel box in Merton's hand.

Seeing this, Merton stretched out his hand and pulled, and a six-foot-long steel ruler was pulled out of the palm-sized box, but this was not the end, with Merton's continuous movements, a steel ruler two feet long appeared in front of everyone.

"A two-foot ruler." Everyone's faces couldn't help but be Hao Ran for a while, Mo Jiazi only asked them to make a zhang long, and it was enough for him to ask even more, so he directly made a two-zhang ruler, which was also controlled with one hand.

"The reason why Mo made a two-zhang long ruler is actually for the convenience of operation, the distance measurement must be accurate, and often requires the cooperation of two people, and this steel ruler only needs one person to operate to ensure its accuracy. I can easily measure the distance to the bridge deck by standing still," Merton said, picking up a two-zhang ruler, folding it in half, and pressing the end directly against the edge of the bridge, sliding the bent part continuously.

"One foot two feet five cents and two centimeters!" As soon as Merton's hand was forced, he saw that the steel ruler that was originally bent was straightened again and returned to its original state.

Gong Yihong couldn't help but sigh, Mo Jiazi is really extraordinary, this steel ruler can be rigid and soft, it is simply a combination of a wooden ruler and a cloth ruler, this alone has already surpassed the other two I don't know how much.

"One centimeter!" But Li Yun couldn't help frowning when he heard this precise number, he was only accurate to the fifth centimeter at most, and he really didn't know how the Mo family's centimeter was measured.

Morton saw Li Yun's doubts, and said with a smug smile: "Wooden rulers and cloth rulers are limited by material limitations, so they naturally can't be accurate too much, but steel rulers don't have such defects, and they are accurate enough to be accurate to one centimeter. ”

As he spoke, Morton exerted a slight force on the steel ruler in his hand, and suddenly moved sideways in front of Li Yun and Gong Yihong.

"Sure enough, it's accurate!" The two of them saw the subtle scale on the steel ruler, and couldn't help but be shocked, the scale of the steel ruler and the wooden ruler are all engraved, and then printed with ink, and once the wooden ruler is too accurate, it will destroy the structure of the wooden block, and it will soon wear out, and the same is true for the cloth tape measure, if it is too accurate, then even the most advanced ink of the ink magazine, will spread into a ball of ink, but the solidity of the steel perfectly solves these two hidden dangers, under the precision instrument of the Mo family, it is perfectly engraved with a width of one centimeter, and it is very easy to distinguish.

"In addition, the best use of the steel ruler is to measure inside the object, especially the inside of the house, which can be easily completed by one person." Merton said, while showing the various ingenious uses of the steel ruler, which is simply a perfect combination of the advantages of folding ruler, wooden ruler, and cloth tape measure.

"Even, when we are finished, we only need to gently loosen this hidden buckle, and the steel ruler can be perfectly folded in the palm of the hand, in fact, this should be called a steel tape measure." Merton moved in his hand and turned on a switch of the steel ruler, and there was a rattling sound, and the steel ruler automatically retracted and became the size of a palm again without anyone controlling it.

"Master, it's really amazing!" Wu Meiniang sincerely admired that Merton's hand was much more powerful than her manual operation of the cloth tape measure.

"Mojia Trick!"

Li Yun couldn't help but feel proud, the Mo family's machine technique is what the Mo family is most proud of, and the machine technique is also the strength of the Xiangli family.

However, Li Yun guessed wrong, the clockwork technology inside the steel tape measure is not owned by Mojia Village, but is taken from the dolls of the Deng Ling lineage, from a street trick to help the national economy and people's livelihood.

"The three heroes of the Mo family!" Gong Yihong couldn't help but sigh.

The Mo family has been silent for thousands of years, and there are still so many talents, and the wisdom of the public losers is extremely poor, but they can't crack it, and the three people of the Mo family actually made a kind of ruler, which directly includes the ruler of the near, middle and far distances.

Gong Yihong can predict that these three rulers have been on the market and will definitely be popular in Datang, and the original Luban ruler may no longer be able to compete with it.

"I lost!" Li Yun said calmly, this time he didn't complain at all, because Merton's steel tape measure was too amazing.

Mocun shook his head and said: "This time, there is no loser, the three rulers can be said to have their own strengths, and how can they divide the winners and losers, even the Luban ruler, which is the most commonly used by carpenters today, seeks to avoid evil in the construction of houses, and it is not up or down, and this game can make a draw is not an exaggeration." ”

"As it should be!" The public loses the donkey road under the slope.

At this point, the battle between the two veins of the Mo family officially came to an end, and in the three competitions, Li Yun of the Xiangfu clan played against the Moton of the Xiangli clan.

Two defeats and one draw!
