"You kid, why are you so wary of your aunt and grandmother?" The Empress Dowager Dou couldn't help but chuckle out loud, and put her finger on Dou Yan's forehead. "Good grandson, if your aunt doesn't believe you, how can this son ask you?"

The kind of selfless trust revealed in these words, only a strong intimacy, which moved Dou Yan to work, well, no matter what, the old lady has said this, and she still has to hide it, which is really in vain to betray the old lady's trust.

"After my grandson was hit by the thunder, he kept thinking about how to stop the thunder from hurting people's lives. Therefore, I have been observing why the thunder falls...... "Dou Yan spat and starry and put the facts in front of Mrs. Dou and Chen Ajiao, at least, he gave an answer to these two after processing and evolving the thunder and lightning knowledge he learned in later generations.

"Do you mean to say that hardware is more beneficial than wood and stone?" Mrs. Dou is worthy of being Her Majesty the Queen Mother, who is full of poetry and books, at least this sentence directly points out the truth that Dou Yan spent at least half a pillar of incense to reluctantly explain.

"That's right." Dou Yan nodded, took the water that Chen Ajiao kindly handed over and drank it all, well, for the sake of her friendly act, we will temporarily record the act of selling and counting the money in the account.

"Since you said you could prevent it, how can you prevent it?" The old and refined figure of the Empress Dowager Dou still has a face of encouragement and appreciation, which makes Dou Yan, a young man from the 21st century, feel a sense of being valued.

Well, if you want to play a full set, giving up halfway is not Dou Yan's way of doing things, when even if someone brings silk paper and pen and ink, Dou Yan will use a fine pen on the silk paper to depict on the side, while explaining the so-called lightning protection device.

Anyway, Dou Yan has seen a lot of real things about lightning rods on those high-rise buildings in later generations, and he can often see that thing when he goes to the roof to smoke when he is studying.

Of course, since it is an ancient royal building that needs to be beautiful and consistent with the architectural style, it is natural to process the wire or copper wire into other shapes. Although Dou Yan has never been a teacher, after all, he has been a student for nearly 20 years, at least he knows how to express his meaning clearly in simple words, and the lightning rod is really simple to the point of outrageous, unless it is a special person whose IQ is so low that it is outrageous, or a special person whose brain does not think about hooking back, Dou Yan really can't understand who would not understand, well, this is a bit winding, but this is the truth!

"A mere iron wire or copper coin of this thickness, casually fixed on the roof of a house and buried in the ground, can stop the heavenly fire?" Chen Ajiao pursed her lips, looking disbelieving. "How is it possible for such a simple object?"

Although Mrs. Dou did not express her emotions, Dou Yan could also see the hesitation in her eyes, although Dou Yan said that the idea of a lightning rod was forced, but since she had already said it, then Dou Yan naturally couldn't let these people take their works seriously.

Dou Yan snorted and said, "Sister Gillian, the world is so big, there are no surprises. If you don't believe it, my aunt can choose a towering ancient tree, next to it to tree a tall tower, with iron wire or copper wire as a fork, the lower end is buried in the ground, in the season of thunderstorm, this tree will not be affected by the misfortune of that day. ”

"Who knows if you are bragging, although there are not many towering ancient trees in our Chang'an City, there are not a few. Over the years, I haven't seen all the thunderbolts in the sky. It's someone who ...... "This big-eyed soft Lori evolved into a fanged Lori at this moment.,Two cute tiger teeth are also like two cobra fangs, and they also shine brightly.,It's hard to see.。

"What do you mean, girl? Did someone recruit you or mess with you? Dou Yan was furious, the tiger's body shook wildly, the so-called birth of a girl is tolerable, mature women are unbearable, cough cough, well, in a word, this little girl is simply challenging the authority of this lightning mitigation and disaster prevention expert in the Han era.

"Be quiet for the old body!" Mrs. Dou couldn't help but hold her forehead, and it seemed that she had a headache for the two grandchildren.

"Grandma, Gillian is not messing around." Chen Ajiao stuck out her tongue at Dou Yan, with a provocative expression.

Dou Yan directly gave this stinky girl the back of her head. "Auntie, if you believe in your grandson, choose some palaces and ancient trees in Changle Palace to install this lightning rod, and you can know that your grandson is right."

"That's true." Old Lady Dou couldn't help but interject.

"Well, that's what it means, thank you aunt and grandmother for your teachings, my grandson is making someone angry." Dou Yan said solemnly in the laughter of a certain fanged Lori.

"Okay, dignified man, how can you worry about little Gillian all day long." Old Madam Dou smiled and patted Dou Yan's hand. "That's it, Wu Shun, do you understand?" These words were addressed to the middle-aged eunuch who had been standing quietly and silently behind her.

The slaves and maids understood. I don't know what the Queen Mother commanded? When the eunuch heard this, he immediately knelt on the ground and replied.

"Well, if you are clear, then go to these drawings and find some craftsmen to ask......" The old lady Dou instructed the eunuch unhurriedly, Dou Yan naturally listened to it, well, the old lady adopted her own opinion, fortunately, she finally did not waste so long of saliva.

"Remember, this is the will of this palace." Mrs. Dou finally confessed, and Wu Shun, who seemed to belong to Mrs. Dou's personal eunuch, nodded understandingly: "The slave and maid understand, if the queen mother has no other instructions, then the slave and maid will retire first." ”

After the old lady Dou motioned for him to step back, Chen Ajiao couldn't help but leaned into the old lady's ear and muttered, Dou Yan thought about it with her little toes, and knew that this stinky girl must be saying that her idea was not solid or something.

However, Mrs. Dou just smiled and patted Chen Ajiao's hand, and said lightly: "It's okay, everything is taken care of by the old man." Hmm, just now the words of our ancestors and grandchildren, we must not leak half a sentence, do you two know? The old Empress Dowager Dou narrowed her eyes, which were originally not easy to use, but the ability that was reflected there made people feel a chill in their hearts.

"Thank you, Grandma." Dou Yan understood very well in his heart the reason why this old lady who sincerely cared for her did this, and Chen Ajiao next to her seemed to be very sensible and considerate, and immediately nodded and made a guarantee.

Then it was time to enter the game, an old man and two children continued to fight hard with playing cards in the main hall of Changle Palace, killing Gillian, the big-eyed Lori, with a proud smile, and the old lady's hearty laughter was endless, only Dou Yan was sweating alone, well, it seems that the gambling luck was exhausted after the crossing, whether it was the local owner or the improper owner, Dou Yan never won a game.

When it was getting late, the old lady originally wanted to keep Dou Yan and Gillian to continue the game after dinner, where did Dou Yan dare to stay and look for abuse, although it was her responsibility and obligation to accompany the old lady to play cards and kill time, but the problem was that there would always be a pimple in her heart if she was abused too much.

The old lady reluctantly let go of Dou Yan, but specially told Dou Yan to come to the palace to play when he was free. If there is anything new in the rectification, don't forget that her aunt is.

Dou Yan naturally agreed without a word, and then said goodbye to the old lady and fled in embarrassment, and there was a smug laugh from Gillian's fanged Lori behind him. Depend on!
