Standing at the entrance of the underground palace of the Mausoleum of the First Emperor of Qi Shihuang, standing in front of this huge black door, the traces of vermilion lacquer more than 2,000 years ago can still be vaguely identified on the door.

Countless people want to peek into the secrets of the underground palace, but no one has succeeded for two thousand years, and too many mysterious legends have given this tomb of Qi Shi Huang a mysterious veil.

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

Tomb robbers watched the treasure and were buried alive during the excavation.

Of course, there are also armies who want to blow up the gates of the dungeon, but the strange plague has wiped out the entire army.

Legend has it that many poisonous snakes and beasts guard the dungeon and kill those with evil intentions.

Legend has it that an army of the undead guarded the area and protected their emperor.

......

However, no matter how terrifying the legend is, it is true that the underground palace has not been developed so far, and compared to Qin Shi Huang of another world, the location of the mausoleum of Jiang Yan, the first emperor of Qi, has always been recorded in the history books.

Moreover, it has not been regarded as a tourist development zone, and no terracotta warriors and horses have been excavated.

The reason for this is not known to the public, but it is not a big deal, and it is just one less tourist attraction left and right.

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

This kind of synthetic fuel is by no means a simple chemical reaction can be obtained, according to his sister's words, this fuel must have a modern laboratory to synthesize, after all, two thousand years of direct exposure to the wind and sun, but not completely rotten fuel is not a simple thing.

Although after this, Wang Junrong also said other things about the underground palace, but Wang Junling, who was not interested in this, didn't pay much attention to these, so he just left a simple image in his mind that "this underground palace hides a big secret".

As for the reason why such a thing couldn't be left in Wang Junling's mind?

It was about that time that Wang Junling's first love had just been sealed in the mountain behind Siming Middle School, after all...... The little boy who has just fallen in love, the age of innocence, coupled with such a great change in emotion, Wang Junling probably can't hold anything else in his mind at this time.

Ah, the cardamom years of youth......

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

"I'm not actually from this world, I'm a time-traveler in popular terms. ”

As Tong Zhao's words fell, Li Qifu and Wang Junling, who had shocked expressions on their faces, wanted to show shocked expressions, but the sudden buzzing sound choked on the words they wanted to ask.

The gate of the underground palace that has been sealed for 2,000 years...... It's opened!

......

......

Walking into the gate of the underground palace, Wang Junling and Li Qifu were shocked by the scene.

They walked in the dungeon passage without the slightest sense of simplicity and heaviness, and there was not the slightest cold, rotten, and dark aura around them, nor were there any traps, traps, or dead corpses.

"Bili~ Cleaning is complete, ready to return to the nest" A blue-and-white butterfly-shaped robot became the "messenger" who welcomed them into the dungeon

That's right, it's not so much a dungeon as it is a scientific research laboratory that transcends modernity.

The blue-and-white butterfly robot just now, if Wang Junling remembers correctly, should be a newly emerging sweeping robot on the market, but look at the rounded shape of this robot and the obvious state of moving by levitation......

Why is a dust-sucking sweeping robot still suspended in the air?

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

The sweeping robot flies to the middle of the cylinder, opens the opening in the belly of the machine to expel the garbage and dust, and then slowly raises the position at the top of the cylinder, and then gets stuck there safely.

...... This level of technology is a bit out of the ordinary.

"The environment that has just been renovated recently, and the robot was also brought by me from the research room of the Mars base, that 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 of 2,000 years ago, when I didn't even reach the level of technology in the last century, otherwise I would have set off the second industrial revolution. ”

As he spoke, Tong Zhao sighed.

"The sorrow of the liberal arts students, coupled with the fact that I later served as a soldier and did not go to university, so there is a lack of knowledge in science, although I have crossed it, although I know what the formula of gunpowder is sulfur, saltpeter, and charcoal.

But I still know what charcoal is, I have never seen sulfur, and I don't know what the hell saltpeter is.

I knew that I would add a little scientific knowledge when I wrote it, and it was a dead end!"

Tong Zhao's spit obviously did not resonate with Li Qifu and Wang Junling, and Li Qifu, as an "ancient" who had completely recovered from ancient times and only had a high level of modern Chinese, and who had mastered the use of computers, cars, mobile phones, fighter planes, and warships, did not dare to speak at all.

"What do you call a traverser...... "Wang Junling doesn't have any concerns about this, after all, although Wang is not a mobile library + supercomputer like his sister, he doesn't know how to let Wang Junling make explosives and gunpowder, old airplanes, automobiles, smelting steel, and manufacturing firearms......

These siblings are really not normal human beings by nature.

"Literally, but you don't have to worry about what kind of parallel universe or anime you are.,I know a lot of the Internet.、Film and TV.、Fan comics and so on have these settings.。

But you're not, I'm just coming from another planet in the universe.

Of course, from the very beginning, I also thought that I was traveling through a parallel world, even if there are two moons here, but I still think so, especially when I saw the Yellow Emperor Gongsun Xuanyuan, I told you, that guy is also the same time-traveler as me.

Oh, I forgot to mention that there is only one moon in my hometown, the Earth where I used to be, and that is the most significant difference between our two worlds.

As for the rest, you have to know that we liberal arts students don't study astronomy, how far the earth and the moon are, how far the earth is from the sun, how many planets there are in the solar system, I don't have any reflection at all!"

Tong Zhao was not embarrassed at all, even if these things were obviously high school knowledge points.

Look, this is the use of reading, read more books and read more newspapers, otherwise you can only be a dick when you cross over, learning advanced knowledge, in fact, it is to lay a solid foundation for future crossing.

It's really good to read a lot of famous books, don't read the book and forget it quickly, and it's also good to memorize two more ancient poems.

Don't think that Tang poems and Song lyrics come easily after crossing over, those bigwigs who write stories such as traveling through ancient times and being writers are all copied on the Internet when they write those poems.

If someone really writes directly without opening the search software, and the background knowledge is readily available, then the author's women's clothing is not a possible thing.

"Are you saying that Gongsun Xuanyuan is also a traverser like you?" Li Qifu finally couldn't help but express his doubts after Tong Zhao told such a past.

。 The whole book m.
