"My son, the day you were born, the whole of Lordaeron ...... Ahh......h Oh no, it's Caesar......"

Marin frantically scribbled out the lines he had just written, and then tore out the first page......

"Damn, how did I come up with the first 'Great Filial Son' of Azeroth? That's a father-killing bastard! ”

Marin is on a new page and continues to write......

What is he writing about? He's writing what he left for Caesar. The main purpose is to educate Caesar in the future, such as psychology, thick black science, "The Art of War", "Thirty-six Strategies" and other textbooks. At the same time, there are also textbooks for physics, chemistry, biology, geography and other future use.

And the first passage is actually a preface written by Marin and something like that, which mainly tells Caesar the source of this knowledge. Then, unconsciously, Marin remembered the message from the king of China, the classic game in his previous life, to the prince. But thinking of the prince's unfilial act of killing his father, Marin still tore up that paragraph.

"If I can come back safely, I have to strengthen the education of filial piety for my son in the future!" Marin thought viciously.

It is true that he is a time-traveler, but he can only guarantee that the scientific and technological knowledge he has can beat the natives of this era, but he cannot guarantee his son's filial piety. If he really raised a white-eyed wolf and made a move to kill his father, then he would be really wronged.

A good heir is very important, but it is often difficult for a strong monarch to give birth to a strong heir. For example, Qin Shi Huang...... No, he had a good heir, but he was killed...... For example, Liu Bang, who gave birth to a prince Liu Ying is a wreck; For example, Emperor Wu of the Han Dynasty, the crown prince Liu Ju was a reckless guy, and he actually committed suicide in anger; There are also Li Chengqian, the crown prince of Tang Taizong, and Yinren, the prince of Kang Mazi...... They are all typical examples of the sons of the Ming Lord. Even Qin Shi Huang's eldest son, Fusu, was a fool, otherwise he would not have made his father angry and was killed in the end. If it weren't for being degraded to the frontier, but sitting in Xianyang, even if Zhao Gao and others wanted to do something, there would definitely be a large number of ministers willing to protect it. But if you are degraded, it is useless......

Moreover, according to the European system, only the eldest son could inherit the throne. Unlike Kang Mazi, the crown prince is abolished, and he can still set up the capable old Si Yongzheng as the heir. Besides, Marin is now a legitimate heir to Caesar, and he doesn't have a spare tire if he wants to change it......

Therefore, Marin can only hope that Caesar will rise to the ......

Because the voyage was dangerous, Marin didn't know if he would be able to return safely from this trip. Although we deliberately avoided the typhoon season and chose to sail in winter, when the sea is the most peaceful, there are still certain risks. Therefore, Marin decided to first compile everything he wanted to teach Caesar into a book and leave it to Caesar. Of course, not now, but if you can't come back in two years, you will give it to him.

For this purpose, Marin specially built a hut out of cement in the backyard of the royal palace. When all the books are compiled, put them in. Then, seal it with cement.

If he can't come back in two years, let Angela send someone to smash open the sealed cement hut, take out these "cheats", and give them to Caesar.

If he comes back, he will also smash open the sealed cement hut and hide or destroy these "cheats" to avoid falling into the hands of others.

And these "cheats" are collectively called "Traveler's Notes" by Marin......

……

In order to prevent these cheats from being stolen by outsiders and learned, Marin specially wrote them all in Chinese characters. In this way, even if the hostile forces steal it, they will not be able to understand it.

And Marin can instruct little Caesar to follow Sconda and other subordinates who understand Chinese to learn Chinese characters, so that he can understand these "cheats". Moreover, before Marin left, he would specifically instruct Sconda and others to prohibit teaching others Chinese and Chinese characters, so as to avoid the cheats being understood. Even Angela and Marin didn't let them teach her Chinese......

For Marin, these secrets can only be learned by his son. And Angela ...... If she did die, his papal father-in-law would most likely arrange for her to remarry another nobleman. After all, Angela is still very young, and maybe she will have sons with other big nobles in the future......

If Angela knew the confidential contents of "Traveler's Notes", although she would not leak it casually, she would definitely teach her future and other people's sons. At that time, his son Caesar will not be able to enjoy this exclusive secret. Even, there will be a half-brother who will become a strong competitor......

Therefore, Marlin will never allow Angela to know the secrets of "Traveler's Notes", especially the future technology within. The main ones are top secrets such as strategic technology such as the Mini rifle......

Other secrets, such as the principles of airplanes and automobiles, are nothing even if they are known. Because, the existing technology is destined to not be built. But the Minnie rifle is different, this thing can be made with existing technology. And, if it does, it can sweep across Europe.

The reason why Marin is now reluctant to come up with the secret of the Minnie rifle is that he is afraid that he will be learned and become his fierce rival.

Because, once the technology of the Mini rifle spreads, when the time comes, the mortality rate of the war will become extremely high. When the time comes, it will be time to compete with the population of each country.

Everyone has a Mini rifle, and you can't replenish it when your people die, and I will replenish tens of thousands when my people die...... There's no comparison......

Think of the 19th century war, the Crimean War, in which 256,000 people were killed and wounded in Tsarist Russia because of the use of murderous weapons such as the Mini rifle. But Tsarist Russia, with a population of tens of millions at the time, could afford such casualties.

But Beihai has a population of only 1 million people, and the number of strong men is not much different from the casualties of Tsarist Russia during the Crimean War. If a populous country like France really wants to get super technology like the Mini rifle, the Beihai Kingdom will definitely not be able to fight each other.

Therefore, until the northern half of Germany is occupied, Marin does not intend to unleash this super technology indiscriminately. Even with the use of single-headed ammunition technology, only a small number of die-hard loyalists have come into contact with single-headed ammunition.

But in order to prevent the leakage of the one-headed ammunition technology, Marin will give Kohler an order before leaving - if he can't come back, all die-hard loyalists who have been exposed to the one-headed ammunition must also be eliminated. After all, these diehards are their own diehards, not Caesar's. If they can't come back, after a long time, these people may have other thoughts. It would have been miserable if they had gone to France and other big countries with secrets. Therefore, if you can't come back, this secret must also be temporarily destroyed. Wait until Caesar is old and let him take it out again......

……

In addition, since it is called "Notes of a Traverser", Marin also revealed the secret of being a traverser in the book. However, in order to show his status as the "chosen son", Marin did not say that he was a Chinese soul who crossed over to become a European knight, but made a slight change, describing himself as "on the night of sleeping on the haystack, with the help of the great sage Einstein, the soul went out of the body, traveled through time and space, traveled through China hundreds of years later, and after learning a lot of knowledge there, the soul returned to the original body"......
