“Nan Wenyuan!”

Hearing this, Gu Nanzhi couldn't help but straighten up, looking at the skylight above his head, and said, "Go, help me get some soil near the skylight!"

"yes!"

Nan Wenyuan had finally managed to secure the task of being Gu Nanzhi's guard team leader, and he responded without hesitation when he heard the words.

soon.

He brought back the soil near the skylight.

He also considerately collected soil from several directions and divided it into small bags.

After Gu Nanzhi took the soil, he opened it and began to compare it with the soil under the burial pit...

The soil quality is similar, all a little burnt.

It's like it was burned!

The guess in his heart was confirmed, and Gu Nanzhi couldn't help but murmured: "That's not a robbery hole..."

Her guess was right!

No tomb robber would dig such a big hole!

That is...

Formed by meteorite impact!

Thinking of this, Gu Nanzhi couldn't help but take out the access card he carried with him...

Although her access card was small, it was made of a special material. Objects falling from high altitudes, regardless of size, would generate high temperatures due to friction with the atmosphere...

Coupled with the effect of gravity acceleration, the access card can easily penetrate the top of the ancient tomb when it falls to the ground. Because of the obstruction of the ancient tomb top, the speed of the access card when it falls to the ground is greatly reduced. When it really falls into the tomb burial pit, it does not cause major damage, but is buried in the soil...

Regardless of whether it is the skylight or the burial pit, there will be burn marks due to the high temperature when the access card falls!

If that's the case, then it all makes sense...

When her access card fell to the ground, it was like a tiny meteorite!

The appearance of robbery holes in the ancient tombs and the breaking of a large number of porcelains in the burial pits may have been caused by the impact of this "small meteorite"...

Thinking of this, Gu Nanzhi couldn't help but sigh.

Her access card...

He's quite capable of getting into trouble!

There were so many places to land, but they chose an ancient tomb as the landing point!

this……

How many funerary objects would have to be smashed!

"What's wrong? Nannan."

Liu Xiya heard what Gu Nanzhi said just now and looked at her in confusion, "How do you know that it wasn't a hole made by tomb robbers? We have investigated and found traces of people passing through that hole. The tomb robbers entered the ancient tomb through that hole!"

Gu Nanzhi heard: "..."

So, there are more than just burial pits!

The reason why this ancient tomb was visited by tomb robbers was probably because her access card happened to fall here, making a big hole in the ground, exposing the location of the ancient tomb and attracting tomb robbers...

"Were there many burial objects stolen from this ancient tomb?"

Thinking of this, Gu Nanzhi couldn't help but ask.

“It should be quite a few!”

Liu Xiya nodded: "After all, the regulations of this ancient tomb are not low!"

Gu Nanzhi: “…”

What a sin!

It was all her access card’s fault!

It has nothing to do with her!

"However, although a lot of it was stolen, the broken funerary objects in the burial pit still provide a lot of archaeological value after restoration!"

Liu Xiya said again.

Gu Nanzhi: “…”

The burial objects that were smashed by her access card became the fish that slipped through the net of the tomb robbers, but it was a pity for her mother...

"Mom and Dad, you spent a lot of effort to excavate those broken funerary objects, right?"

"Isn't it? Your father, my colleagues and I have been here for more than half a year, digging protectively every day, for fear of missing a small fragment..."

Gu Nanzhi: “…”

What a sin!

After silently apologizing in her heart, Gu Nanzhi put the matter behind her and started chatting with her parents about random things. She even visited the ancient tomb...

Now she was basically certain that her access card had come through with her soul!

However, the access card separated from the shuttle when it landed, so the landing points of the two are not the same!

The landing point of the access card is in this ancient tomb.

The landing point of the shuttle is most likely the big mountain in Shanxia Town.

As for why Gu Nanzhi was so sure that the two had separated instead of being separated after landing, it was very simple, because there were indeed traces of meteorite impact here, but the traces were not big enough...

The time machine is much bigger than the access card!

The impact caused by the time machine landing is definitely not just a hole as big as a skylight!

The impact crater alone could have been thousands of meters deep...

so……

This is definitely not the landing point for the shuttle.

After getting the answer they wanted, Gu Nanzhi and her parents visited the ancient tomb and then chose to return to Beijing.

After returning to Beijing, Gu Nanzhi found a way to contact Shanxia Town and sent a message to Xie Zhenting, asking him to focus on underground searches and use the metal detection device she gave him. Her shuttle might have crashed into the ground...

And if it crashed itself into the ground, Gu Nanzhi could explain why its stability maintenance device failed!

There is no sunlight underground!

No solar energy!

There are no cosmic particles to capture either!

The shuttle's stabilization device can only last for a short time, but it can last this long...

I think it was the nuclear power device used for interstellar shuttle that automatically pushed up the cylinder!

However, the use of nuclear power requires regular care and maintenance!

Counting from the time her shuttle arrived at this plane in the book, it has been at least twenty years...

Having just completed the long journey of interstellar shuttle travel, she had to take over the subsequent stability maintenance work. This was really far beyond the service life of the nuclear reactor she had designed for the shuttle. It had been in service for too long and was on the verge of collapse!

Not to mention...

During this period, it also found a carrier that was in tune with her soul and successfully allowed her to "travel through the book"!

This requires a huge amount of energy!

Her nuclear reactor...

Thanks for your hard work!

"Hold on, little one, just hold on until I find you!"

Gu Nanzhi prayed silently, and a glimmer of hope arose in his heart.

if……

If her guess was true, and the shuttle's stabilization device malfunctioned only because of a lack of power, then as long as they could find it, bring it back to light, and restart the solar panels, the stabilization system would be able to continue working!

If that's the case...

perhaps……

The plane collapse between her and Xie Zhenting can be contained!

Maybe she doesn't have to leave the world in the book and can stay here!

Thinking of this, infinite hope ignited in Gu Nanzhi's heart, and he became more motivated to work, but...

With a red heart and two prepared hands, her teaching work did not change because of this discovery!

Everything is just her guess and inference!

Until it is confirmed, she will still do her best to keep the spark for her country's scientific cause!

In this way, another half month passed. After Xie Zhenting and others worked as searchers in the depths of the mountains for half a month, and Gu Nanzhi worked as a teacher in Beijing for half a month, the international dispute over the sea area of ​​Xia State finally came to a conclusion...
