They are in the past history and already have a clear understanding of the future development process of this country.

"These are all technologies of the future. I have read all the books Aunt Cai left behind." Jiang Niannian said, "If you are interested, we can learn together."

The technology of the future...

The technology of the future cannot be used in the past to speed up the process of history.

Although this can indeed rapidly improve national strength, military power, science and technology, etc.

But this goes against the order of the universe. Every stage of historical development has its own specific trajectory that cannot be interfered with by external forces.

Once order is destroyed, even if technological strength is improved, it will surely suffer a devastating blow one day in the future.

They need to follow nature, follow historical development, and follow the laws of the universe.

Otherwise, they wouldn't have been stranded in this world for so many years and wouldn't be unable to do anything. It's not that they can't do anything, but that they can't do anything.

However, they also provide some technical support and assistance, and have trained a large number of top students.

Gao Han was among them.

He is one of the most outstanding high-tech talents.

He had learned about 70% to 80% of the technology they brought from another world.

The remaining 20% were not because Gao Han could no longer learn, but because they did not dare to teach him anymore. They were afraid that if they continued to teach, the order would be disrupted.

Because the techniques he is learning now are already at least seventy or eighty years ahead of the world.

So they decided not to teach anymore.

If future technology does not reach a certain level, it will be useless even if you learn it.

"These techniques are not suitable for inclusion in textbooks, but I can teach you. Maybe you will find them useful in the future."

"What do you mean?" Song Qingdai's intuition told her that this was the reason why Jiang Niannian brought her here today.

"Didn't Uncle Cai tell you?" Jiang Niannian blinked.

Said: "The key has been found. As long as we have enough energy, we can go back at any time, back to the world that originally belonged to us, and you will go back with us."

Song Qingdai frowned: "I never said I would go with you. I belong to this era."

"Since you don't belong to this era, you should indeed return to your own era, but I am different."

Jiang Niannian's face changed, and she stepped forward to hold her hand: "Comrade Song, what nonsense are you talking about!"

"Your mother is Cai Xuehua, who belongs to the Xingyuan era, just as my father is Jiang He. Then I am the same as my father, belonging to their era, and I should go back!"

"After we go back?" Song Qingdai asked her, "are we going to abandon everything I have in this era?"

Including Gao Han.

"People who don't belong to this era should go back."

"Comrade Song, I'm not discussing this with you. I'm just telling you in advance that you've also seen these technologies that belong to the future. The future is bright, thousands and tens of thousands of times brighter than here!"

"In the future, as soon as your children are born, they will be able to live in a spacious and bright house, where everyone will have equal opportunities to receive education, and there will be no war or killing."

"The law is also the most sound, it will protect everyone who is persecuted, not like in this era..."

"Miss Jiang!" Song Qingdai interrupted her: "As you said, history has its own development trajectory, so the imperfections of this era will definitely become sound in the future."
