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

Lin Ou already knew what this name means. The word comes from his son-in-law. Originally, his grandson should have called him grandfather, but grandfather's name is more concise and respectful, so he accepted it happily.

"Oh, okay, just sit down. Have Xiaohai and Xiaotian finished their homework today?" Now, Lin Ou is not only studying some classics every day, her most passionate thing is to teach her two grandchildren.

Although his grandfather’s question sounded particularly kind, the two little ones looked even more solemn, and they nodded quickly and said, “Grandpa has finished.”

"Well, that's good." Lin Ou nodded. He didn't ask much. Anyway, the professor would check it tomorrow. If he found that the two were lazy, there were ways to let them understand the consequences.

After that, everyone sat down and the food was slowly brought up. The old rich man's life was comfortable if someone served him.

During this period, Lin Ou said to Liu Feiyun: "Feiyun, my father has almost finished reading many books in the house. Let me put down the classics for the time being. Can you let the empire get more books of new knowledge? When I listened to the other gentlemen in teaching Xiaohai and the others for my father, I felt very interesting."

"Okay, no problem. I'll let the empire bring a set of things over at that time." Liu Feiyun agreed directly. This knowledge does not need to be hidden from his father-in-law. However, he also reminded: "Father-in-law, the new knowledge is mathematics, physics, chemistry, biology, etc., and the numbers and biology are connected with the present. However, physics and chemistry are brand new knowledge, which need to be gradually progressed and started from the basics, otherwise it will be difficult to understand. If my father-in-law doesn't understand, you can ask me or a few gentlemen if you don't understand at that time."

"Okay, then I will give you more advice." Lin Ou punched him.

Liu Feiyun also greeted him speechlessly: "Natural, natural."

Well, birds of a feather flock together. After staying together for a long time, many aspects will always be unknowingly affected.

"Okay, eat, eat." The dishes were served, and Lin Yuxue greeted everyone to start a meal.

If you eat without saying a word, most of you will eat quietly with your father-in-law. If there is no urgent matter, you will wait for the meal before you talk about it.

After dinner, he took a walk, drank tea, and Lin Ou went back to study books. Liu Feiyun expressed his affirmation. Although he could not do it, he admired such a person, serious and hardworking.

The two children are now growing up a lot and are sensible. Although they often need to watch Liu Feiyun and his wife, they can occasionally let Xiaolu take care of them.

After sitting in the front hall for a while, Liu Feiyun went back to the room and said love words to Lin Yuxue, and she tried to move from time to time, which made her very shy.

The love is sometimes natural to the depths. But just as they were about to communicate well, the door was suddenly knocked, and then the voices of his two sons came.

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

"Mom, I miss you."

Liu Feiyun said that he was helpless when he was disturbed. He was just his own child and he was not easy to get angry.

Lin Yuxue naturally saw Liu Feiyun's expression and tapped his chest gently and said, "First accompany the children, the night is long, and there are opportunities behind you."

"Okay." Liu Feiyun hooked her nose, then kissed her on the face: "Please sort out your clothes first and see what this little guy has discovered, and how long it took, this little guy really sticks to you."

"Hurry up, don't let the kids wait in a hurry."

After a while, Liu Feiyun opened the door and let the two children come in. He asked, "Xiaohai, what have you discovered? I'm 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 could tell at a glance that this is axle grass, but it

There are four leaves. Generally, there are only three leaves of the mutated four leaves. It is difficult to find one of the 100,000 plants, but it is a symbol of luck.

Liu Feiyun had talked to them about this thing before. For all the time, the two little guys would go to the fields to look for it, but unexpectedly, they really found it. How lucky they were.

Liu Feiyun smiled and said, "Xiaohai, Xiaotian, you are so lucky that you can find such a treasure. But you must be careful not to ruin it. Go to the craftsman in the village to seal this up so that they will not wither."

"Okay, then I'll go find the craftsman uncle right away." Liu Feiyun said this, and Liu Hanhai couldn't wait. Liu Haotian, who was beside him, first looked at his parents, and then ran away with his brother, but it was still fun to follow him.

In this situation, Liu Feiyun shook his head and said to Lin Yuxue: "Look at your son, I just said I miss you, so I turned around and ran away."

"Isn't it your son, let them go?" Lin Yuxue gave Liu Feiyun a white look, and then she said to Xiaolu: "Xiaolu, don't let them play too crazy."

"I understand, Miss, son-in-law."

The little guy left, and Liu Feiyun and his wife just hugged each other and talked about love and chatted. Who knew when the children would come again? Some things would be quietly coming until late at night.

Life is very comfortable and happy, but one day, Liu Feiyun's family was having a meal, and the earth suddenly shaking, and Liu Feiyun's face changed: "Earthquake, everyone goes out and go to the open space."

Without caring about too much, Liu Feiyun picked up his two children and urged him. But he was also confused. According to records, there has been no earthquake here since ancient times. It should not be in the earthquake zone. Why did he suddenly feel a tremor? Could it be that the aftermath of a major earthquake occurred 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 yard, Lin Ou said with lingering fear: "Is this the earth dragon turning over?"

Perhaps some so-called myths may be true, after all, he can be reborn, but Liu Feiyun believes it is science, because myths are only some science that cannot be reached at present.

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

"That's it." Lin Ou had no problem finding the roots. He probably understood something about Liu Feiyun's meaning, and waited for him to learn it slowly if he didn't understand it. This feeling of exploring new knowledge deeply fascinated him.

Liu Feiyun and others did not enter the house immediately, but instead asked someone to build a few tents on the open space. It is not clear whether there will be any reluctance.

During this period, he ordered Liu Yi: "You ask the empire to check what's going on and see if there was an earthquake?"

"Yes, Your Majesty, the Imperial Intelligence Network is spread throughout the Central Plains. There is a tremor in Yuyang County. It should not be too far apart. I believe that if there is any situation, they will pass it back immediately."

Liu Yi's statement Liu Feiyun agrees with that even if the earthquake occurs on the sea, there will definitely be some strange phenomena if such a large amount of movement.

Indeed, a few days later, the information about this time appeared on Liu Feiyun's side, but this time it was not a so-called earthquake, but a meteorite falling from the sky, landing in Xijing City, which was once the country of Xihao, and the entire city became a huge pit.

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

Fortunately, this place was occupied by the Western Regions coalition forces. After the people fled, the current Central Plains countries were afraid of the unknown forces and have not occupied a large number of places invaded by the Western Regions coalition forces in the past.

But the death is certain. Even the intelligence personnel of the Yanhuang Empire suffered huge losses, and the corpse was hard to find. The explosion scene like a mushroom cloud was simply

It's a nightmare.

After Liu Feiyun learned about this information, he took the lead in giving people relevant pensions, and then he fell into deep thought.

Yes, now our country's technology is changing with each passing day, but it still cannot reach the level of its previous life. Without radar and satellites, it is impossible for foreigners to predict these days. This is definitely the most dangerous existence.

Naturally, we always need to be respectful of it. It seems that the people of the empire need to study the relevant knowledge. Because the thought was liberated, and Liu Feiyun provided the empire with a lot of basic knowledge, the empire has entered the electrical age and its use of electricity is very mature.

Although Liu Feiyun forgot a lot of historical knowledge about his past lives, he still vaguely knew that after three industrial revolutions, human beings still had a later technological era from the steam era to the electrical era, in fact, it was only about two hundred years.

Since they can develop rapidly from scratch, how can their own empire not be able to do so? Human creativity is infinite. Today's empire is full of talents, so it will be absolutely feasible to continue to win over talents related to the Central Plains with the strength of the whole country.

So he immediately said to Liu Yi: "What I said next is that you will record it word by 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 entire world."

"Yes, Your Majesty!" Seeing that Liu Feiyun was so solemn, Liu Yi did not dare to slack off at all.

Liu Feiyun slowly expressed his thoughts: "First of all, in terms of communication, telephone, mobile phone, and human voice propagation is generated by vibration, electricity also has pulses, and radio, the strength of the current will generate radio waves, and information can be loaded through modulation. Communication can start from this aspect. The empire is now studying, but it requires more material and manpower."

He didn't know very clearly, so he could only try hard to recall something he knew. The next one was aerospace technology, which is a comprehensive discipline that involves all aspects, but in short, it is to use technology to fly into the sky.

"Early aircraft, rockets, the Empire has also been researching this aspect. Fuels and new materials are extremely important and require continuous experimental formulations, such as titanium alloys..."

Liu Feiyun said a lot, but in the end he thought of another one, saying: "A small number of people will be organized to study astronomical telescopes. The principle is similar to that of telescopes. However, I asked 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 are any abnormalities."

This is the quickest way he has thought of to explore outer space, but he doesn't know if the astronomical telescope can detect meteorites in advance. However, he thinks that it should be possible, as long as it continues to be upgraded.

After saying that, Liu Feiyun exhaled and asked, "Have you recorded it all?"

"All records are done, no word is wrong." Liu Yi handed a stack of paper in his hand to Liu Feiyun.

After reading it, Liu Feiyun felt that there was no problem and said, "Okay, pass it back as soon as possible, no mistakes should be made."

"Don't worry, even if you die, you will send this manuscript back safely."

After Liu left, Liu Feiyun also had a lot of thoughts in his heart. His constant comfort made him lack a lot of sense of crisis. He didn't have to worry about sudden disasters in his previous life. The country would do a comprehensive monitoring. But now, perhaps the probability of a person encountering a natural disaster in his life is very low, but the low possibility does not mean that there is no.

Take typhoons as an example. Not to mention that there are typhoons every year, there will be one or two occasionally. If you are not lucky, it may be more than one year. Although you can identify them in advance, the specific level cannot be known. If it is a super typhoon, the houses in Yuyang County will definitely be irresistible.
