"Ink Technique!" Everyone took a deep breath.
This was the power of Ink Technique. The emergence of a brand new Ink Technique would bring earth-shaking changes to the Tang dynasty and a great impact on the entire industry.
Now, it was not only the Tang dynasty that was protecting the Mo family, but also the Mo family that was pushing the Tang dynasty forward. It was not that the people of Chang 'an were racking their brains to enter the Ink Technique exhibition, but if they missed the exhibition, they might lose the initiative and suffer a crushing defeat.
On the other hand, if they could seize the initiative in the exhibition, they would certainly be rolling in money. For a moment, the sharp people present had seen too many business opportunities.
Selling pesticide sprayers was a necessity for farmers, and would certainly make a profit. Once they mastered the grafting technique, they could plant fruits and melons and sit under a tree to count money every year. If they entered the dock and station business and used the Mo family's machinery, they would certainly save manpower and greatly improve efficiency. They would look down on their peers.
One step ahead, one step ahead. This Ink Technique exhibition had already brought too many surprises to everyone.
"Mechanics is the core of Ink Technique. In addition, optics also gave me a big surprise." Meton reached out and put on a pair of glasses.
"Myopia glasses!"
"Reading glasses!"
Everyone in the stands shouted one after another.
"Oh! Looks like everyone already knows! "Meton pretended to be helpless.
Everyone immediately chuckled.
"Then I'll tell you something you don't know. As everyone knows, reading glasses can help the elderly regain their eyesight, but you don't know that there's another wonderful use for reading glasses," Meton said.
Many people were immediately curious. The price of reading glasses was not high, and many old people in Chang 'an were now equipped with a pair. Many of the old people present were wearing reading glasses.
"This is just a small Ink Technique for everyone's amusement. You can pick up your reading glasses and put the back of your hand against the sun. Then you'll know." Meton kept them guessing.
"Oh!"
At that moment, many old people's childlike innocence was aroused and followed Meton's instructions.
In the box, the slanting sun shone in. Li Shimin held a magnifying glass that Meton had specially prepared and pointed it at the ground. On the ground, there was an unusually bright spot of light.
"Ah! It hurts! "
Pande suddenly exclaimed. He quickly put down his reading glasses and blew at the back of his hand.
"Old man, you've fallen into Meton's trap!" Li Shimin laughed.
Pande was momentarily stunned. "Who would have thought that this light spot would be so hot?"
At this moment, many people also realized that after being under the light for a long time, the temperature had risen greatly. They were not paying attention and immediately cried out in pain.
In the crowd, Quan Wanji, who was dressed like an ordinary person, held the back of his hand and glared at Meton hatefully. "How dare you disrespect your elders!"
"What's wrong with that? It's just a harmless joke!" An old man next to him looked at Quan Wanji with displeasure. In his opinion, this wasn't a big deal. Instead, it was fun. He picked up his reading glasses again and looked at the bright spots curiously.
Meton snickered. "I believe everyone already knows the magical use of reading glasses. Everyone only looked at it for a short while and already felt unbearably hot. What if it was for a long time?"
Meton picked up a magnifying glass that was the same model as Li Shimin's and shone it at a brazier filled with soft straw from five steps away. Not long after, the brazier actually emitted wisps of green smoke. Then, a flame appeared and quickly ignited the brazier.
"Fire in the air!"
"Divine skill!"
Everyone exclaimed as they looked at the raging flames.
Meton only used a magnifying glass and actually ignited something in front of everyone's eyes.
In the box, Li Shimin was dumbfounded as he looked at the flames that kept coming out of the brazier in front of him. Meton had also left a similar set of tools for him in the box. If Li Shimin hadn't followed Meton's steps and ignited the flames himself, he probably would have exclaimed in surprise.
"What the hell is going on?" Quan Wanji touched his reading glasses and was shocked. He couldn't figure out that the glasses he always wore had such a function.
"Could it be that spot of light?" Wei Sian asked doubtfully.
Quan Wanji suddenly understood.
"That's right. It's that spot of light that ignited the flames. Light is a common thing that humans see around us. Light can bring warmth to the earth, allowing our eyes to see things clearly and allowing plants to grow faster," Meton said emotionally.
Everyone in the stands nodded slowly. The effect of light was too great, yet it had always been overlooked.
"The School of Mo has always been researching the Dao of Light and Shadow. In the first Mo Arts Exhibition, I said that if you want to spear a fish, you must spear the bottom part of the fish. I'm afraid that many of you have already tested it. Also, when you put a chopstick into a bowl of water, it seems to break. This is all due to the refraction of the sun," Meton said.
"Refraction!" Everyone nodded.
"This time, it's the same for the reading glasses. It's just that the reading glasses refract the sunlight from the entire lens to a single point. This way, the temperature of the sunlight will increase by several times, and only then will it ignite the flames," Meton explained the principle one by one. Everyone was enlightened.
"The School of Mo is unrivaled in the Dao of Light and Shadow!" Pande exclaimed.
Li Shimin nodded slowly. This was the difference between the School of Mo and the rest. The other schools only knew how to do it and didn't ask for the reason, but the School of Mo directly asked for the root of the matter. If it were a witch or a deity, they would've probably pretended to be mysterious and cheat people of their money.
"Of course, other than refraction, it can also reflect sunlight. Meton casually pulled out a bronze mirror and placed it under the sunlight. Meton turned the mirror slightly, and suddenly, a strong ray of light was reflected and swept across the audience.
"Mo Jiazi!"
"Aiya! My eyes! "
…
Everyone immediately covered their eyes and cried out in surprise.
"Brat Mo, just you wait!"
Pande also covered his eyes and said hatefully. Suddenly, he remembered that Li Shimin was still here and quickly turned around.
"Your Majesty, you're not dead, right?"
"Of course I'm fine!" Li Shimin waved his hand and said.
Unknowingly, Li Shimin had already put on a pair of sunglasses and was sitting there leisurely. The dazzling sunlight didn't affect him at all.
"Hehe! I don't mean any harm. It's just a joke. However, long-term exposure to the sun will cause blindness and visual impairment. Fortunately, the School of Mo has recently developed a new type of glasses called sunglasses! " Meton said as he took out a pair of sunglasses and put it on. With a slight gesture, one of Mo Jiazi's younger brothers immediately took out a bronze mirror and reflected the sunlight onto Meton's face.
"Everyone, as long as you wear sunglasses, you won't have to be afraid of the dazzling sunlight," Meton put on the sunglasses and walked leisurely under the dazzling sunlight.
