"Hello grandpa." The two children stood up very politely and greeted their grandfather.

Lin Ou already knew what this title meant, this word came from his son-in-law, originally his grandson should call himself grandfather, but his grandfather was more concise and respectful, so he gladly accepted it.

"Hey, okay, sit down, have Xiaohai and Xiaotian completed their homework today?" Now Lin Ou is not only studying some classics every day, but also teaching his two grandsons.

For his grandfather's questioning, although it sounded extraordinarily kind, the two little ones looked even more solemn, and quickly nodded: "Grandpa has finished it." ”

"Well, that's good." Lin Ou nodded, he didn't ask much, anyway, the professor will check tomorrow, if the two of them are found to be slack, there is a way to make them understand the consequences.

After everyone sat down, the dishes were slowly served, and the life of the old rich man was comfortable when someone served him.

During this period, Lin Ou said to Liu Feiyun: "Feiyun, many of the books in the house have almost finished reading for my father, for the sake of putting down the classics for the time being, can you let the empire get more books of new knowledge, and when my father listens to several other gentlemen teach Xiaohai and them, I feel very interesting." ”

"Okay, no problem, I'll let the empire ship a set when the time comes." Liu Feiyun directly agreed, and this knowledge does not need to be hidden from his father-in-law, but he also reminded: "Father-in-law, the new knowledge is mathematics, physics and chemistry and biology, etc., mathematics and biology are connected to the present, but physics and chemistry are brand new knowledge, and they need to be gradual and start from the basics, otherwise it will be difficult to get through, and my father-in-law can ask me or a few gentlemen if he doesn't understand at that time." ”

"Okay, then the virtuous son-in-law will give me a lot of advice." Lin Ou gave him a fist.

Liu Feiyun also saluted him speechlessly: "Naturally, naturally." ”

Well, this thing gathers like like, and if this person stays together for a long time, many aspects will always be unconsciously contaminated.

"Alright, eat, eat." The dishes are ready, and Lin Yuxue beckons everyone to start eating.

Eat without saying a word, have your own father-in-law in most of the quiet eating, if there is not something urgent, wait until after the meal.

After dinner, the walk of walking, the tea drinker, and Lin Ou went back to study books, Liu Feiyun affirmed this, although he couldn't do it, but he admired such a person, serious and hardworking.

The two children have grown up a lot now and are sensible, although Liu Feiyun and the couple still need to watch many times, but occasionally they can let Xiaolu take care of them.

After Liu Feiyun sat in the front hall for a while, she went back to the room to talk to Lin Yuxue, and from time to time she moved her hands, which made her shy.

This affection goes to the depths, and sometimes it just comes naturally. But just as they were ready to talk, there was a knock on the door, followed by the voices of his two sons.

"Daddy, open the door, I've found something good."

"Mother, I miss you."

It was a good thing to be disturbed, Liu Feiyun said that he was helpless, but it was his own child, and he was not easy to get angry.

Lin Yuxue naturally saw Liu Feiyun's expression, and gently knocked on his chest and said, "Accompany the children first, the night is long, and there will be opportunities later." ”

"Okay." Liu Feiyun hooked her nose, and then kissed her on the face and said, "Tidy up your clothes first, see what this little guy has found, and it's only been a long time, this little guy is really sticky to you." ”

"Hurry up, don't keep the kids waiting."

After a while, Liu Feiyun opened the door to let the two children in, and he asked, "Xiaohai, what did you find, you were in a hurry." ”

"Father, look." Liu Hanhai took out a piece of grass like a treasure.

Of course, this is not an ordinary grass, Liu Feiyun can tell at a glance that this is an axle grass, but it has four leaves. Generally, the axle grass has only three leaves, and it is difficult to find one of the 100,000 plants with such a mutated four-leaf plant, but it is a symbol of luck.

Liu Feiyun had told them about this thing before, all often, the two little guys would go to the fields to look for it, but they didn't expect that they really found it, how lucky they were.

Liu Feiyun said with a smile: "Xiaohai, Xiaotian, your luck is so good, you can find such a treasure." But you have to be careful, don't break it, and go to the craftsman uncle in the village in a while, and ask them to seal this so that it won't wither. ”

"Okay, then I'll go to Uncle Craftsman right away." As soon as Liu Feiyun said this, Liu Hanhai was a little impatient. And Liu Haotian on the side first looked at his parents, and then ran away with his brother, or followed his brother for fun.

In this situation, Liu Feiyun shook his head, and he said to Lin Yuxue: "Look at your son, I just said that I miss you, turn around and run." ”

"Isn't it like your son, let them be." Lin Yuxue glanced at Liu Feiyun, and then she said to Xiao Lu: "Xiao Lu, don't let them play too crazy." ”

"Got it, Miss, Uncle."

The little guy left, Liu Feiyun and his wife just hugged each other and talked about love, chatting, who knows when the children will come again, and some things will stay until the dead of night and then come quietly.

Life is very comfortable and happy, but one day, Liu Feiyun's family was eating, and suddenly the mountains shook, and Liu Feiyun's face changed: "Earthquake, all go out and go to the open space." ”

didn't care too much, Liu Feiyun directly picked up his two children and urged. But he also had doubts in his heart, according to the records, there has not been an earthquake here since ancient times, it should not be in the earthquake zone area, why did he suddenly feel the tremor, could it be the aftermath of a major earthquake in other places?

The earthquake came and went quickly, and there was no movement in just a few breaths. Standing in the open space outside the courtyard, Lin Ou said with palpitations: "Could this be the earth dragon turning over?" ”

Maybe some of the so-called myths may be true, after all, he can be reborn, but Liu Feiyun believes more in science, because the use of myths to describe is only some science that cannot be touched at present.

He explained, "Father-in-law, this could be an earthquake, and the earthquake, which you can learn from the new knowledge of the empire at that time, is a natural phenomenon, not some earth dragon. ”

"That's right." Lin Ou didn't have the problem of finding his roots, he probably understood something after listening to Liu Feiyun's meaning, and some of the things he didn't understand were waiting for him to learn slowly, and this feeling of discovering new knowledge could deeply fascinate him.

Liu Feiyun and the others did not enter the house immediately, but asked people to set up a few tents in the open space, and it is unclear whether there will be aftermath.

During this period, he instructed Liu Yiyi: "You let the Imperial Check what is going on and see if there is an earthquake somewhere?" ”

"Yes, Your Majesty, the imperial intelligence network is all over the Central Plains, and there is an earthquake here in Yuyang County, it shouldn't be too far apart, I believe that if there is a situation, they will pass it back immediately."

Liu Yi's statement Liu Feiyun agrees, even if the earthquake occurs at sea, there will definitely be some anomalies with such a big movement.

Indeed, a few days later, information about this time appeared on Liu Feiyun's side, but this time it was not the so-called earthquake, but a meteorite that fell from the sky, and the landing point happened to be in Xijing City, which was once the Xihao Kingdom, and the entire city was reduced to a huge crater.

I have to say that this Xihao country is really full of disasters and difficulties.

However, fortunately, this place was occupied by the Western Regions Alliance Army at the beginning, and after the people fled, the current Central Plains countries were also afraid of the unknown forces, and now they did not occupy the places occupied by the Western Regions Alliance Army in the past.

But the dead are certain, and even the intelligence personnel of the Yanhuang Empire have suffered huge losses, and the bones are difficult to find, and the explosion scene like a mushroom cloud is simply a nightmare.

For this information, Liu Feiyun took the lead in asking people to make relevant pensions after learning about it, and then he fell into deep thought.

Yes, now their own country's science and technology are changing with each passing day, but after all, it has not reached the level of the previous life, there is no radar, there is no satellite, and it is impossible to predict these foreign visitors, which is definitely the most dangerous existence.

Naturally, there is always a need to be in awe of it, and it seems that the people of the Empire must study it. Because the mind was emancipated, and Liu Feiyun provided a lot of basic knowledge for the empire, the empire has initially entered the electric age, and the use of electricity has been very mature.

Although Liu Feiyun has forgotten a lot of historical knowledge about his previous life, he still vaguely knows that after three industrial revolutions, from the steam age to the electrical era and the later era of science and technology, it is actually only about two hundred years.

Since they can develop rapidly from scratch, how can their own empire not be, human creativity is unlimited. Today's empire is full of talents, and it is absolutely feasible to continue to attract relevant talents in the Central Plains to mobilize the power of the country.

So he immediately said to Liu: "What I said next, you record it word for word, and then pass it back to the empire, this matter must be taken seriously, and it is far higher than the strategy of conquering the whole world." ”

"Yes, Your Majesty!" Seeing that Liu Feiyun was so solemn, Liu Yi didn't dare to slack off.

Liu Feiyun slowly said his thoughts: "First of all, in terms of communication, telephone, mobile phone, the transmission of human voice is generated through vibration, and there are pulses in the case of electricity, and there is also a radio aspect, the strength of the current will produce radio waves, and the information can be loaded through modulation, communication can start from this aspect, the empire is now researching, but it needs to invest greater material resources and manpower." ”

He doesn't know very well, so he can only try to recall some of what he knows, and the next thing is aerospace technology, which is a comprehensive discipline that involves all aspects, but in short, it is the use of technology to make people fly into the sky.

"Aircraft, rockets, this aspect of the empire is also already researching, fuels and new materials are extremely important, and need to constantly experiment with formulations, such as titanium alloy ......"

Liu Feiyun said a lot, but in the end he thought of another one, and said: "There is also an organization of a small group of people to study the astronomical telescope, which is similar to the principle of the telescope, but I ask to be able to see the celestial bodies in the sky, and then form a special group of people to observe the astronomy and find out if there is any abnormality." ”

This is the fastest way he can explore outer space at present, but he doesn't know if the astronomical telescope can detect meteorites in advance, but in his mind, it should be possible, as long as it is constantly upgraded.

After speaking, Liu Feiyun exhaled and asked, "Have you recorded everything?" ”

"It's all recorded, word for word." Liu Yi handed a stack of papers in his hand to Liu Feiyun.

After reading it, Liu Feiyun felt that there was no problem and said: "Okay, send it back as soon as possible, there must be no mistakes." ”

"Your Majesty can rest assured, even if you die, you will send this manuscript back safe and sound."

After Liu Yi went, Liu Feiyun also had a thousand thoughts in his heart, and the comfort he had been lacking a lot of sense of distress, he didn't have to worry about sudden disasters with the technology of his previous life, and the state would do a good job of all-round monitoring, but now, maybe the probability of a natural disaster in a person's life is very low, but the low probability does not mean that there is none.

As far as typhoons are concerned, Yuyang County does not say that there are them every year, but occasionally one or two, and if you are unlucky, you may have more than one a year. Although it can be identified in advance, the exact level is not known. If it is a super typhoon, the houses here in Yuyang County will definitely not be able to resist it.

"It seems that the people of the empire have to rebuild the houses again, all of them are replaced with reinforced concrete, just one or two floors, and I believe that the typhoon problem can be roughly solved."
