Taozhi looked at him happily: "Can this thing be mass-produced in the factory?"


    Xie Yanjun had a smile on his face: "Yes."


    He suddenly has an idea now, Ah Xiao can do this business together!


    Nowadays, many people cannot afford electricity, but this lamp can solve many problems.


    As long as there is a battery, and the cost of the battery, as long as the cost of the battery is kept to a minimum, there will never be a loss.


    Xie Yan held this thing: "I decided to cooperate with the factory to make this lamp in hand and make it available to the whole country, and then I can make a lot of money!"


    "The lamp in your hand?" Taozhi laughed when she heard the title: "It is indeed the lamp in your hand."


    Xie Yan put it on the table, and he went to serve the meal: "Daughter-in-law, why do you seem to be very suspicious."


    Taozhi sat opposite him: "No, I just think it can be called a flashlight instead."


    Xie Yan frowned: "flashlight?"


    Taozhi nodded: "Yes, the electricity in my hand is still in the shape of a tube, so it can be called a flashlight, which is easier to understand than the lamp in my hand."


    Xie Yan''s eyes lit up, he picked up his flashlight and studied it: "Yes, this name is not bad!"


    He opened it twice, and the light was still very bright, which could directly illuminate the road ahead.


    "It''s called a flashlight!!" He put it down, with an uncontrollable smile on his face: "I''ll bring it back to the factory tomorrow."


    "Daughter-in-law, the book you gave me is really great. I read and found a lot of things that are amazing. Although I don''t know some words, it doesn''t affect my understanding at all."


    Xie Yan grabbed the rice and said, "Especially those who draw pictures. I understand it right away. It''s very interesting! Daughter-in-law, do you want to study the circuit together? Actually, there are a lot of great truths in it.


    Taozhi was holding the bowl, listening to him being so excited, and looking at the flashlight he invented, I really admired him.


    Why is Xie Yan so smart...


    She felt that she was not very smart.


    Especially in the sciences, it''s really a huge flaw.


    "I''m not that promising." Taozhi sighed: "Maybe this is fate."


    "Especially, if I''m a fool for three years, I might be a fool for nine years."


    After all, being three pregnant must be a foolish nine years.


    Xie Yan put down the bowl: "It turns out that being pregnant will make you stupid, daughter-in-law, your performance has become more and more obvious recently."


    Taozhi stared at him with sharp eyes, I can say I''m stupid, but I don''t want to hear you say I''m stupid! !


    "Actually, I also found out that I''ve become stupid recently." Xie Yan hurriedly held a bowl of rice to please her when she saw her expression: "Maybe this is also a chain reaction that his father would have as a child."


    Taozhi rolled his eyes: "Hurry up and eat your meal."


    Xie Yan smiled, because the lamp in his hand was ready, and he was in a very good mood.


    The inspiration is that these two days, my daughter-in-law always gets up in the middle of the night in the thatched hut. He installed a lamp in the thatched hut, but the distance of a few meters from the house is pitch-black, so he thought, if the daughter-in-law can get a lamp, All right.


    He has been researching, using battery power to make light bulbs glow.


    The battery is stuffed into a round tube, which is suitable for the daughter-in-law''s hand to hold, and is also convenient.


    He read a lot of books, thoroughly studied the principles of batteries, and made things out.


    Got this hand lamp!


    That is, the flashlight that the daughter-in-law changed her name to!


    Xie Yan is in a very good mood, because it can be used by his daughter-in-law, and he can also take it to the factory to exchange money.
