It's a pity that Dou Yan is not an ophthalmologist at all, and there is no instrument in his hand to measure how many degrees of myopia the old lady has, let alone make lenses with high myopia, but otherwise, Dou Yan also knows that one trick can solve this problem.

That's the magnifying glass, that's right, this thing is definitely a good way to replace glasses for high myopia, although not as good as glasses, but it can make the old lady pick up the bamboo slip from the new, and absorb knowledge from there.

At least the material of the magnifying glass, there is no glass at this stage, so Dou Yan is more concerned about using a substitute for glass: crystal.

Waiting left and right to wait for the little girl to return to the room, Dou Yan had to stand up and stretch out stupidly: "Berne, where is the young lady?" ”

Dou Yan's personal and loyal servant, a dry and thin monkey, but Dou Bone, who is clever and an eighth woman, poked his brain out of the door of the room. The young lady went to the antechamber. Childe, do you want to call the little one? ”

"Huh? That stinky girl isn't going to lean on my black form, right? Dou Yan couldn't help grinning, grandma's, I know that little Lori is not easy to deal with. Forget it, ignore the girl, and go out with my son, by the way, do you know where there is a crystal? ......" Dou Yan doesn't have time to compete with that little girl now, first find a way to give the old lady something good to make a fart and amuse herself.

"Crystals?" Dou Bone scratched his head and slapped his thigh with his big hand: "Son, you are talking about water jade, right?" ”

"Water jade? What the hell? Dou Yan glanced at this guy: "The water spirit I am talking about is the kind of colorless and transparent kind of stone. Occasionally, however, there will be other colors. ”

"Isn't it water jade?" Dou Bonne rolled his eyes covertly and patiently explained to Dou Yan. Dou Yan, one of the four illiterate people in the 21st century, understood that the so-called crystal has three names in this era, one is water spirit, one is water jade, and one is water blue.

The reason why it is called a water spirit means that this thing is like a water spirit. It is called water jade, which means jade like water, and it is also said to be transformed by the ice of thousands of years. What the ancients valued was its texture of "as clear as water and as hard as jade". In the "Classic of Mountains and Seas", the crystal also has another name, which is called the water blue.

Dou Yan couldn't help but look up and down at the loyal servant who was talking eloquently in front of him, staring straight at Dou Bone's heart, and his steps moved back slightly, Dou Yan said stupidly: "Bone, I really can't imagine it, you kid is really capable, and he doesn't look a few years older than me, how do you know so much?" ”

Hearing this, Dou Bone secretly breathed a sigh of relief, and hurriedly said with a smile: "These are all things that I learned from my master's reading before, to be honest, the master's talent is really rare in the world." ”

－－－－－－－－－－－－－－－－－－－－

Hearing this, Dou Yan shook his forehead lightly, and sighed with emotion: "Alas, if it weren't for Gongzi, I had almost forgotten about my previous affairs, wouldn't I know these aliases of the crystal, you say?" These words are completely from Dou Yan's sincerity, after all, as a modern person whose soul has traveled to ancient times in later generations, there will be a sense of superiority, at least Dou Yan is no exception.

"Of course, Childe, you are not bad, you can stand side by side with the master, the small one is really admired and thrown to the ground, if it is not for the child's previous forgetfulness, for these allusions, I am afraid that he is more able to catch it......" Dou Bonne is worthy of being a personal loyal servant specially arranged by his father to the Dou Yan in the previous place, just this mouth, although he dare not say that he can get the trust of that Dou Yan, at least he can get a certain amount of goodwill, he can be regarded as the loyal servant whose heart is higher than the sky and whose life is thinner than paper The former Dou Yan stayed by his side for the longest time.

"Well, hehehe, it's just ordinary, to be honest, it's just that I haven't met anything that this son can do seriously, otherwise ......" Dou Yan was half regretful and half emotional, and walked out of the study with twisted steps, Dou Bonne's face was admired, but he secretly slandered in his heart: "You just play nonsense, you only learned before, and it is not much better than other noble children who only know how to eat, drink and have fun all day long." ”

Dou Yan naturally couldn't hear Dou Bone's heart, if he could hear it, the book should be changed to Xiuzhen or an ability, well, at least Dou Yan took Dou Bone to the front hall with high morale, and sure enough, he saw Dou Zhi's little Lori, and at this moment this little Lori didn't know what she was muttering, which caused a gentle smile from her mother who was on the couch and didn't know what to fiddle with.

"Yan'er, why are you here too?" The mother raised her eyes and saw Dou Yan, and couldn't help but ask with a smile.

"The child is going to see her aunt and grandmother in a few days, and she is thinking about what gift to give her old man, no, she is trying to go out of the house to go yo-o, and by the way see what new things are there." Dou Yan smiled and saluted her mother, her eyes fell on Dou Zhi's body, and the stinky girl pouted: "Brother, you shouldn't have thought of such a reason because you were bored at home, right?" ”

"What are you talking about, although I don't dare to say that I am the most filial person, I know what loyalty, righteousness, courtesy and faith are." Dou Yan glanced at the little girl and snorted.

Dou Zhi made Dou Yan's words stand up in the corners of her eyes, and was about to open her mouth, but her mother couldn't help but speak: "Okay, okay, my mother doesn't have time to listen to your bickering, Yan'er can think like this, that's great, well, you go to the account room to pay some money, and by the way, just take a few people together, you know?" ”

"I'm going too!" Dou Zhi hurriedly declared: "Mother, the child hasn't been out for a few days, okay." The little girl took her mother's arm and began to be coquettish, which seemed to be very in line with Dou Yan's evaluation of her: tsundere.

"Okay, you can go with your brother, but you are not allowed to quarrel outside, and you are determined to let people see jokes, you know?" The mother shook her head helplessly. "Look at you girl, you messed up the calculation on the couch again, and now my mother has to do it again...... Really. ”

"Counting? Mother, are you settling accounts? Dou Yan came to the front and looked at the dozens of calculation chips that were almost half a small table, and couldn't help but feel dizzy.

"Of course, don't settle the accounts, who knows how to arrange the food and clothing at home. Okay, okay, let's go, save my mother from looking at the two of you dizzy. "My mother looked impatient. Dou Yan, who wanted to ask his mother why he didn't need an abacus, had to press this thought, and led his sister out of the front hall in a gloomy manner, saving his mother from being annoyed for a while, and it was the brother and sister who couldn't eat and walked around.

"Brother, what do you want to buy for your aunt?" Dou Zhi sat in the carriage and was also restless, from time to time she lifted the curtain of the carriage and poked her head out to look, the lovely falling horse bun swayed around, revealing a sense of lightness and happiness.

"It's not to buy, brother is to do it." Dou Yan raised his hand and stopped Dou Zhi, a curious baby's little mouth. "Please, you'll know in a while, don't ask OK now?"

"Ou Yu? What does it mean......" Dou Zhi didn't understand what English was, but it didn't hinder her extraordinary curiosity.

Dou Yan rolled her eyes helplessly, simply closed her eyes and took a nap, who Dou Zhi, the little girl, was disturbed by the chirping in her ear, and made up her mind to pretend to be deaf, Dou Zhi had to turn her head stupidly and continue to look at the scenery outside the window. But the pink and ruddy little mouth is still moving, and I don't know what I'm muttering.

Dou Yan was secretly happy in his heart, glad that this trick finally worked, otherwise he really didn't know how to explain what it was OK to Dou Zhi, who was diligent and inquisitive.
