"Ink Technique!" Everyone in the audience took a deep breath.

This is the power of ink technology, a new ink technology appeared, which directly brought earth-shaking changes to Datang and had a great impact on the entire industry.

Now it is not only the Tang Dynasty that protects the Mo family, but the Mo family is pushing the Tang Dynasty forward, not that the people of Chang'an City are trying their best to enter the ink technology exhibition to see the excitement, but if they miss the ink technology exhibition, they may lose the opportunity and fail.

On the contrary, if he can seize the opportunity in the ink art exhibition, he will definitely be able to make money, and for a while, the keen people present have seen too many business opportunities.

Pesticide sprayer on behalf of the farmer, this is a must-have thing for farmers, will definitely make a steady profit, once they master the grafting technology, widely plant melons and fruits, you can sit under the tree every year to count money, if you get involved in the dock station business, the use of Mojia machinery, will be able to save manpower, greatly improve efficiency, proud of peers.

Step by step, step by step, this ink exhibition has given everyone too many surprises.

"Mechanics is the core of ink science, and in addition, optics also gave Mo a big surprise." Merton reached out and pulled out a pair of glasses and put them on his eyes.

"Myopia!"

"Reading glasses!"

Everyone in the stands shouted.

"Oh! It seems that now everyone already knows! Merton said with a helpless expression.

Everyone burst into chuckles.

"Then I'll talk about something that you don't know, as we all know, reading glasses can help the elderly regain their eyesight, and they don't know that reading glasses have a wonderful use in addition to that." Merton said.

Many people were suddenly curious, the price of reading glasses is not high, and now many old people in Chang'an City have already equipped a pair, and many old people present are wearing reading glasses.

"It's just a little ink trick for everyone's enjoyment, you can pick up your reading glasses, face the sun, and put the back of your hand behind you to try it." Merton said.

"Oh!"

At present, many old people are childlike and follow Merton's instructions.

In the box, the sunshine from the west just shone in, and Li Shimin held a magnifying glass specially prepared by Merton and pointed it at the ground, only to see that an unusually bright point of light appeared on the ground.

"Ahh It hurts! ”

Pound suddenly exclaimed, quickly put down the reading glasses in his hand, and blew on the back of his hand.

"You old bastard, but you fell for Merton's scheme!" Li Shimin laughed.

Pang De suddenly burst into wonder: "Lao Chen didn't check for a while, who would have thought that this point of light would be so hot." ”

At this moment, many people also found that the temperature rose sharply under the light spot for a long time, and they immediately cried out in pain if they didn't check it for a while.

In the crowd, Quan Wanji, who was dressed as an ordinary person, covered the back of his hand, glanced at Morton hatefully and said, "It's a big rebellion, and I don't respect the elderly." ”

"What's this, it's just a harmless joke!" An old man next to him glanced at Quan Wanji unhappily, in his opinion, this is nothing, but it is very funny, so he picked up his reading glasses again and looked at the bright light point curiously.

Merton snickered: "I believe you have already learned the wonderful use of reading glasses, you only took a short photo, and you feel unbearably hot, what if it is a long time of exposure?" ”

I saw that Morton picked up a magnifying glass of the same style as Li Shimin, and shone it five steps away at a brazier filled with soft straw, and in less than a moment, wisps of green smoke rose from the brazier, and then a flame rose up, quickly igniting the entire brazier.

"Ignition in the air!"

"Miracle skills!"

Everyone looked at the raging flames and exclaimed.

With just a magnifying glass, Merton set things on fire in full view of everyone.

In the box, Li Shimin was stunned to see the flames of the brazier in front of him, and Merton also left a set of the same tools for him in the box.

"What the hell is going on?" Quan Wanji touched the reading glasses on his eyes, shocked, he couldn't figure out how the glasses he often wore had such a function.

"Could it be that point of light?" Wei Si'an on the side wondered.

Quan Wanji was suddenly stunned.

"Yes, it is that point of light that ignites the flame, light is a common thing in people, right around us, light can bring temperature to the earth, let our eyes see clearly, and make plants grow quickly." Merton said emotionally.

Everyone in the stands nodded slowly, the role of light was too great, but it was never overlooked.

"The Mo family has been studying the way of light and shadow, the first ink art exhibition, in the next said that if the fish is speared, it must be under the fish fork, I am afraid that many brothers have already experimented, and chopsticks put into the water in the bowl, as if broken, this is the refraction of the sun." Merton asked, looking around.

"Refraction!" Everyone nodded suddenly.

"And this time reading glasses are the same, except that reading glasses refract the sunlight in the entire lens range to one point, so that the temperature of the sunlight increases several times, so that the flame can be ignited." Merton explained the principles one by one, and everyone suddenly realized.

"The way of light and shadow, the Mo family is unique in the world!" Pound sighed,

Li Shimin nodded slowly, this is the difference of the Mo family, the other hundred schools know what it is, and they don't ask for it, and the Mo family directly gets to the bottom of it, and its secrets are all over the place, if it is replaced by a witch and a god, I am afraid that he will pretend to be a ghost and cheat people out of money.

Of course, in addition to the refraction accident, the sunlight can also be reflected, Merton casually pulled out a copper mirror and put it in the sun, Merton turned the copper mirror slightly, and suddenly a strong light reflected out and swept the audience.

"Mo Jiazi!"

"Oops! My eyes! ”

………………

Everyone suddenly covered their eyes and exclaimed.

"Mo boy, you wait!"

Pang De also covered his eyes and said hatefully, suddenly thinking that Li Shimin was still here, he hurriedly turned around.

"Your Majesty, you're not dead!"

"Of course I'm fine!" Li Shimin waved his hand.

I didn't know when, Li Shimin had put on a pair of sunglasses and sat there contentedly, and the dazzling sunlight had no effect on him at all.

"Huh! The kid has no malicious intentions, just kidding, but long-term exposure to the sun will cause blindness and impaired vision, fortunately, the Mo family has newly developed a new type of eyes, called sunglasses! Merton took out a pair of sunglasses from his arms and put them on his eyes, and after a slight gesture, a child of the Mo family suddenly held a bronze mirror, reflecting the sunlight on Merton's face.

"Look, as long as you wear your sunglasses, you'll never be afraid of the sun again." Merton wears sunglasses and moves freely in the double harsh sunlight.

"Damn, you're using the sunshine sting just to advertise?" Everyone in the stands looked at Merton's sunglasses and suddenly resented.
