The last time he introduced cotton linter to Zhao Shizhen, after accidentally leaking the secret of nitrocellulose, Zhao Hao made up his mind to keep the secret strictly.

The reason is four words, 'maintain the generation gap'.

As a god with great prophecy...... Oh no, scientists, no one knows better than Zhao Hao that after the Industrial Revolution, the development of science and technology and productivity is no longer linear, and every scientific and technological breakthrough has led to a 'leap' improvement in productivity.

This leads to the combat power of the side that has completed the 'leapfrogging', forming a 'generation gap' for the opponent who is still at the original level.

Generation difference, what a desperate word? Once the generation gap is formed, all the advantages of the right time, place and people are counted, and the only thing waiting for the backward side is failure, repeated failure. It is not until it also completes the 'leap' that it can catch up with the footsteps of the advanced side and have a fair contest with the other side.

Therefore, the backward side will definitely try to smooth out this generation gap at all costs, which is a truth that even 'I Daqing' knows.

Therefore, Zhao Hao is sure that any invention that will cause a generation gap, once it is put into large-scale application, will inevitably be reversely cracked and copied by the opponent, sooner or later.

After all, Da Ming is not playing a single-player game. The other two super-empires of the planet in this era, the Ottomans and Spain, were in their heyday.

In addition to the global empire Spain and the continental empire Ottoman, there is also France that competes with Spain for hegemony on the European continent. The Netherlands, England, which are about to rise in line.

Oh, and there's the Franc machine that shares the earth with Spain.

Zhao Hao's eyes have never stayed only on Daming, he knows that if he wants to embrace the Age of Discovery, he will inevitably become opponents with these countries.

And Zhao Hao knows very well that he is not an immortal genius. If you are a genius, you will not be hit by your own students from time to time.

All his reliance comes from great prophecy. And as his butterfly continues to flap its wings, history will eventually lead to a path that is completely unfamiliar to him.

At that time, all historical knowledge was gone, and only technology could still be his basis.

Therefore, Zhao Hao must be cautious about these key technologies that will cause a 'generation gap'.

After all, being two generations ahead will not bring a greater overwhelming advantage than being one generation ahead. If you want to enjoy the generational dividend for a longer time, you should try to keep your new technology secret and delay the time when the new technology comes out.

In Zhao Hao's view, as long as he can always maintain an overwhelming advantage over the enemy, it is enough. Rushing to come up with unnecessary advanced technology will only shorten the time for the opponent to catch up and make the opponent take fewer detours, which is absolutely harmful to oneself.

If he can make the Ming Dynasty maintain a generation gap of at least two hundred years with Europe, then no matter what his outcome is, the final victory will definitely belong to the Ming Dynasty.

This is the 'limited generation difference theory' that Zhao Gongzi established and practiced throughout his life.

Of course, in the eyes of the Tessians, this theory was almost as infamous as his name, and was therefore called 'the daily curse that had enveloped Europe for four hundred years'.

In fact, even among the historians of the later generations of the Ming Dynasty, his theory is mixed...... Especially in the eyes of those fools who shout that 'science has no borders', he is a narrow nationalism that delays the progress of all mankind.

Fortunately, at that time, Zhao Gongzi had already made an ancient appearance, otherwise he would definitely be so angry that he jumped out of the coffin and exploded the chrysanthemums of these unscrupulous descendants with the Longqing style.

Life is too good to raise fools, this is not a race......

So no matter how soft and hard Zhao Shizhen was, Zhao Hao refused to reveal a word.

It's not about trust, it's about unshakable principles.

Seeing the two end the conversation, Zhao Shizhen sank into the water, gurgling bubbles. Li Chengen walked to Zhao Hao's side with two long legs, and then sat down.

"Drink some." Li Chengen handed the celadon cup to Zhao Hao.

"I'm young." Zhao Hao naturally didn't answer, he glanced at the drunken little lord, who started drinking at the age of twelve or thirteen.

But Zhao Hao respects other people's lifestyles, and Li Chengen is visiting the kiln, so he won't talk nonsense.

Li Chengen also glanced at Zhao Hao, and said meaningfully: "It's not small." ”

"you." Zhao Hao hurriedly used a bath towel to block his vital point.

"Hahahaha......" Li Chengen laughed loudly, raised his head and drank the wine in the cup, threw the porcelain wine glass into the soup pool, and then spread his arms comfortably and sat on the pool wall.

"I'll tell you something serious." He suddenly lowered his voice: "A certain person surnamed Zhao is not very authentic!" ”

Zhao Hao's heart tightened, and he said secretly, could it be that my father's East Window incident happened? Hurriedly kicked Zhao Shizhen, who was still spitting bubbles underwater, away, and said with a forced smile: "Everyone has the freedom to choose his lifestyle, and it's better not to interfere with the younger generation." ”

"Uh......" Li Chengen was stunned for a while, and then said strangely: "Yes, I admit it, you are older than me, but at best, you are my brother, when will you become my elder?" ”

"What? Are you younger than my uncle? When Xiwa heard this, she was furious, and she came to settle the score, throwing the water. He also said that he was my uncle all day long! Your uncle, dare to take advantage of Lao Tzu! ”

"It doesn't make much difference." Lee Seung-eun kicked Xiwa away.

"Ahem...... Zhao Hao coughed awkwardly and said, "Hey, it turned out to be me." ”

"Who else can I say? Of course it's you! Li Chengen said with a look of idiot: "The old-timer is such a good person, it's too late for me to love him, how can I talk about him." ”

"Well, I misunderstood." Zhao Hao pulled a dry cotton towel to wipe his sweat, and said with a dry smile: "What the hell is going on, I listen to this." ”

"What else could it be? My sister! The dead sister raised her voice, glared at Zhao Hao with a complicated mood, and said, "She came all the way from Beijing to find you." It's been more than half a month, and you haven't taken her to your house once. She's going to see your grandfather, and you're still holding back! That's too much, isn't it? ”

Zhao Hao wiped the saliva sprayed on his face, and said with a wry smile: "I have already explained this matter to Mingyue and obtained her forgiveness, haven't you heard her say it?" ”

"Uh......" Li Chengen said in his heart, which pot is not opened, which pot is not mentioned, I don't want to live?

But how can he let people see that his sister actually has something to say to him? He smiled dryly: "I said it." But I drank too much wine, and my memory was not good, so I forgot about it. ”

"Then there's no need to tell you again, you'll forget anyway." Zhao Hao smiled.

After all, he hasn't figured out what kind of hatred his grandfather and godmother have, and he hasn't figured it out yet......

"Uh......" Li Chengen scratched his head and said with a smile: "If you don't say it, forget it." As he spoke, he stared at his eyes again and said, "Don't wronged my sister, you know?!" ”

"Mingyue is also my sister, I will not wronged her if I am wronged." Zhao Hao said lightly.

"But she doesn't just want to be your sister......" Li Chengen looked depressed and muttered in a low voice.

"I know." Zhao Hao did not shy away from this question.

"Uh, you know?" Li Chengen was startled, and immediately sneered: "That's right, she can't wait for the whole Daming to know." How could you not know? ”

"Hmm." Zhao Hao looked up at the bright moon in the sky and showed a wry smile.

"And what do you think?" Li Chengen lowered his voice and asked tightly.

"I just said that." Zhao Hao replied.

"You ......" Li Chengen was a little relieved, and said with a somewhat hideous expression: "You mean, you don't mean that to her?" ”

"How old is she? Fifteen years old! Zhao Hao said with a natural face: "If I have that kind of idea for her, I won't be a beast?" ”
