Li Ke quickly figured out the reason for the relatively slow development of Datang's science and technology, and Temujin's split was the largest war in the history of Datang, and in addition, Datang did not have a big war.

There was no world war, and to be honest, technology did not break out. Li Ke studied it carefully, and when he died, although many disciplines in Datang had begun to make up for it gradually, Li Ke did not pull out the seedlings to help them grow, so many theories and sciences were developing at a relatively slow pace.

After all, if Li Ke wants to thoroughly understand the knowledge he has taken out, it will be difficult for decades.

Li Ke probably flipped over, from his death to 500 years or so, about 400 years, about 100 years of scientific and technological progress from the end of the 18th century to the 19th century.

Mainly, the overall science and technology are steadily improving, and in the past 400 years, many disciplines have been studied, confirmed, and improved.

However, even if the development is slower than Li Ke's first life, the time of 1,400 years is also too long, and today's Datang is much more advanced in science and technology than Li Ke's first life.

For example, in the current Datang, controlled nuclear fusion has been solved! Although it has not been solved for a long time, the Q value of controlled nuclear fusion is already greater than 1, and it can probably reach about 3, and it can already be commercialized.

For example, the chip industry has already completed the production of carbon nanotubes, transforming from silicon-based chips to carbon-based chips.

For example, the notebook that Li Ke is using now and the mobile phone he uses are carbon-based chips.

According to the current plan of the Datang government, about ten years later, the official large-scale construction of the Mars base, Datang has completed the construction of the lunar scientific research base on the moon.

In addition, helium-3 mining in the lunar soil has begun, and the construction and design of a new generation of helium-3 and helium-3 reaction controllable nuclear fusion reactors have been further completed.

But these don't matter, Li Ke is not interested, because although he may be the person who caused Datang to be able to extend to today, the current Datang is no longer his Datang.

He is no longer interested in these, and the current Datang is no longer his Datang.

Li Ke didn't know why he could still come here, but he felt that maybe it was to let him see the world he had created.

Li Ke searched his father again, compared to his exaggerated encyclopedia, there was not much information about his father's encyclopedia.

Although there are records about Tian Khan and so on, they are all brushed aside.

Li Shimin:

Taizong Li Shimin, the father of the greatest emperor of the Tang Dynasty, Shengzong Li Ke, has a mixed reputation in his life, and has done the most wrong thing and the most right thing in his life. First, he braved the world's disapproval and reactionary Xuanwumen changes, killed his brother and killed the enemy, and forced his father to abdicate. But when he was the youngest and strongest, he made a decisive choice, abandoned the tradition, and gave up the throne he had rebelled against for the sake of the people of the Tang Dynasty, and instead sat in the Holy Sect Li Ke.

In this way, it has created the foundation of Datang for thousands of years.

At least many of his father's exploits are not mentioned here, and for people in this era, seeing these may just think that Li Shimin is more wise.

But for Li Ke, it was a different feeling, he knew very well what his father gave up, at least he gave up the highest evaluation of him in history, and threw these to Li Ke.

Li Ke, who was flipping through the encyclopedia, suddenly heard a "drip" sound from the hotel door, and then a girl about twenty years old pushed the door open and walked in.

Seeing Li Ke, the little girl immediately smiled and said, "Brother Ke is awake?" You don't want to check the information, we're going to set off quickly, there are still more than 2 hours before the start of the broadcast, we said today that we are going to visit Qinwangzhuang live, and I have bought all the tickets. ”

Seeing that this girl who was not very outstanding in appearance, a name popped up in Li Ke's mind, Wen Xiaoxin. A small assistant he hired.

Hearing Qin Wangzhuang's name, Li Ke's expression was somewhat strange, but he didn't say anything, just smiled slightly and said, "Okay, you pack up your things, I'll wash up and set off." ”

Starting from the hotel, although the buildings, daily necessities, cars, etc. outside made Li Ke feel very sci-fi, on the whole, it was not beyond his understanding.

Stopped an unmanned taxi, the vehicle quickly drove into the street, and drove to the location of Qin Wangzhuang with great skill.

Li Ke didn't speak, just listened to the little assistant's chattering beside him.

He does have millions of followers, and on a short video platform called Echo, he thinks he is a big anchor, but obviously he miscalculated, or he ignored one point, the population base is different.

The Tang Dynasty still maintains the entire Eurasian continent, including Oceania, and has a total population of 3.2 billion, which is much smaller than that of Li Ke in the first generation.

It seems that his estimate is correct, and if the way the population is treated naturally from the beginning, the population is not growing so fast.

The huge population base naturally leads to apps like short video platforms, and there are three or four in the entire Datang.

In other words, to the point where technology is now, many APPs are diversified and compatible with various contents.

And with a large population, he, an anchor with millions of fans, can't talk about a big anchor, of course, although he can't talk about a big anchor, he can still make a lot of money.

Although the predecessor spent a lot, now there are more than 300,000 deposits in the bank card, and he can be regarded as a rich man.

Soon, Qinwangzhuang arrived, and Li Ke also saw the huge visitor center at the entrance of Qinwangzhuang, as well as the sign of the 5A-level tourist attraction, Li Ke didn't know what kind of mood he should be.

He hasn't gone inside yet, and he doesn't know what else can be left here after more than 1,400 years of wind and rain, but Chang'an City has never suffered from war, although the entire Tang Dynasty has been chaotic, and there have been various problems, but all in all, it has come to this day in general peacefully.

Chang'an City, which has not experienced war, even the city walls are now perfectly preserved, but a few city gates have been enlarged, and a few city gates have been reopened to ensure the passage of vehicles.

Through the ticket gate, Li Ke and Xiao Xin did not choose to take the shuttle bus, but entered on foot, and when they stood in front of the archway of Qinwangzhuang, Li Ke silently stopped his steps.

"Brother Ke, then we're on the air." Xiao Xin said in a low voice.

"Okay." Li Ke smiled and nodded, nervous but not nervous, he has been an emperor for more than 80 years, open a live broadcast and tell him to be nervous? He didn't even know what nervousness was, let alone being separated by a network.
