Standing at the entrance of the underground palace of Qi Shihuang Mausoleum and standing in front of this huge black door, the traces of red paint from more than two thousand years ago can be vaguely identified on the door.

Countless people want to peek into the secrets of the underground palace, but no one has been able to succeed in two thousand years. Too many mysterious legends have put a mysterious veil on this mausoleum of Qi Shihuang.

Some bandits were rampant and wanted to find out, but they died unexpectedly.

A tomb robber was watching the treasures, but was buried alive during the excavation.

Of course, some troops wanted to blow up the gate of the underground palace, but the strange plague wiped out the entire army.

Legend has it that there are many poisonous snakes and beasts guarding the underground palace and killing those with ulterior motives.

It is said that there is an army of undead guarding here and protecting their emperor.

...

However, no matter how terrifying the legend is, it is true that the underground palace has not been developed so far. Compared with Qin Shihuang in another world, the location of the tomb of this Qi Shihuang Jiang Shan has always been recorded in historical books.

Moreover, it was not regarded as a tourism development zone, nor was it excavated.

The hidden reasons are not known to the public, but this is not a big deal. There is only one tourist attraction missing.

But Wang Junling actually knew a little secret because some of the information about the gate of the mausoleum, his sister once told him that the vermilion on the door was not actually plant fuel, but a synthetic fuel that was very similar to modern fuels.

Such synthetic fuels are by no means obtained by simple chemical reactions. According to my sister's words, this kind of fuel must be synthesized in a modern laboratory. After all, fuels that have been directly exposed to wind and sunlight for two thousand years, but have not yet completely rotten are not simple things.

Although Wang Junrong also talked about other things about the underground palace after this, Wang Junling, who was not interested in it, did not care too much about these, so he just left a simple reflection of "This underground palace hides a big secret."

As for why such a thing cannot be deeply reflected in Wang Junling's mind?

It was probably because Wang Junling's first love was just sealed in the back mountain of Siming Middle School at that time. After all,... the little boy who had just started to fall in love was extremely innocent and with such a huge emotional change, Wang Junling probably couldn't hold anything else in his mind at this time.

Ah, those young years...

Standing in front of the door for a long time, Wang Junling recalled it for a long time before Tong Zhao turned around slowly.

"I'm not actually a person from this world. In a more popular way, I'm a time traveler."

As Tong Zhao finished speaking, Li Qifu and Wang Junling, who had a shocked expression, were about to show a shocked expression, but the sudden buzzing sound made them choke in their mouths when they wanted to ask questions.

The gate of the underground palace that has been covered with dust for two thousand years... is opened!

...

...

When they entered the gate of the underground palace, Wang Junling and Li Qifu were shocked by the scene.

They walked in the underground palace passage without a trace of quaint and heaviness, and there was no trace of coldness, decay, darkness around them, nor any mechanism, trap or dead bodies.

"bili~cleaning is completed, ready to return to the nest" A blue and white butterfly robot became the "messenger" to welcome them into the underground palace.

That's right, it's better to say that this is a scientific research laboratory that is beyond modern times than that.

If Wang Junling remembered correctly the blue and white butterfly robot just now, it should be the sweeping robot that just emerged on the market. However, looking at the round appearance of the robot and its obvious state of moving on the suspension...

Why can a dust-sucking robot still float in the air?

Moreover, Wang Junling obviously saw a robot floating on the walls and ceiling. Wang Junling also noticed that the robot was flying towards a cylinder about two meters high. The space of about one meter in the lower half of the cylinder looked like a box.

The sweeping robot flew to the middle of the cylinder, opened the opening of the belly of the machine to discharge the garbage and dust, then slowly raised the position at the top of the cylinder, and then stuck there safely.

...This technology level is a bit beyond the scope.

"I just renovated the environment recently. The robot was also taken from the research room of the Mars base, which is your father." Tong Zhao said to Li Qifu, who pretended to be calm and Wang Junling, who was shocked.

"Don't worry, this is not the technology from two thousand years ago. At that time, I didn't even reach the level of technology in the last century, otherwise I would have set off the second industrial revolution long ago."

As he said that, Tong Zhao sighed.

"The sadness of liberal arts students, and later I worked as a soldier but didn't go to college, so I lacked science knowledge. Although I traveled through time, I knew what the formula of gunpowder was sulfur, saltpeter, and charcoal.

But I can know what charcoal is, I have never seen sulfur before, and I have never figured out what the hell is saltpeter.

I had known that I would add some scientific knowledge when I was writing novels, but writing novels was a dead end!”

Tong Zhao's complaints obviously did not resonate with Li Qifu and Wang Junling. As a "ancient man" who had completely recovered from the ancient times and had only the level of modern high school education, and had a specialized operation of computers, cars, mobile phones, fighter jets, and warships, he did not dare to speak at all.

"What are the time travelers you are talking about... are they?" Wang Junling didn't have such concerns. After all, although Wang is not a mobile library supercomputer like his sister, he didn't know how to make Wang Junling build explosives and gunpowder, older models of aircraft, cars, smelting steel, making guns, etc....

In essence, the siblings cannot be considered normal humans.

"Literally, but you don't have to worry about what kind of parallel universe you are or what kind of novels and animation works you are in. I know that many online novels, movies, TV, fan comics and so on have these settings.

But you are not, I just arrived at this planet from another planet in the universe.

Of course, from the beginning, I thought I was traveling through a parallel world. Even though there were two moons here, I still thought so, especially when I saw Huangdi Gongsun Xuanyuan, I told you that guy is also the same time traveler as me.

Oh, I forgot to say that my hometown, that is, the earth where I was originally located, only one moon was in the sky. This is the most significant difference between our two worlds.

As for the others, you have to know that we liberal arts students don’t learn astronomy. How far is the distance between the earth and the moon, how far is the distance between the earth and the sun, how many planets are there in the solar system, I have no reflection at all!”

Tong Zhao was embarrassed to say that, even though these things were clearly the knowledge points in high school.

Look, this is the use of reading. Read more books and newspapers. Otherwise, you will still be a loser after traveling through time. Learning advanced knowledge is actually laying a solid foundation for traveling through time in the future.

It is also great to read more classics if you really can't do it. Don't forget to read the book quickly. It is also great to memorize two more ancient poems.

Don’t think that Tang and Song lyrics can be easily picked up after traveling through time. Those bigwigs who write stories about traveling through time and time as literary tycoons in ancient times always copy those poems on the Internet when writing them.

If someone really doesn't open a search software and write it directly, and has complete background knowledge, it is not possible for the author to wear women's clothing.
