Who told him to make the cards!

Chen Zhi glanced at the time.

Five o'clock in the afternoon.

He finished his bottle of mineral water, crumpled it, and casually tossed it into a roadside trash can before slowly walking toward the archaeology classroom.

Having decided to pursue the prize money from the competition, Chen Zhi was no longer in a hurry to take on new orders.

With more than ten days left until the end of the academic year, he can take this opportunity to practice more, attend more classes, and learn more about the structure of the Moon Crown Card Formation so that he can have a good exchange with some senior students later.

By the way, he should also consider his own card.

The card case that Shen Qinglian gave him had six compartments: three card slots and three energy slots.

His level 3 is just right.

But now he doesn't have a single complete card in his card slot, so if something really happens, he won't be able to protect himself.

……

7 PM.

Chen Zhi and Zhou Keke returned home.

I'm not going out today.

Chen Zhi was already very familiar with this area, and he had even memorized part of the underground city card array, many of which could be found in ancient versions of the Moon Crown Card Array.

It can only be said that knowledge is everywhere.

But learning too much can be tiring.

He went a bit too far with his mental training today, and he's still feeling a little dizzy.

Chen Zhi decided to reward himself with a half-day rest.

After dinner, he went to the bathroom to take a shower.

Zhou Keke then took all the antiques off the shelves in the store, preparing for a major cleanup.

She has been holding a grudge ever since Chen Zhi exposed her for being a fraud.

I've studied archaeology for so long, how come I'm still so bad at it?

According to my mother, there's more than just that one counterfeit item in the house.

So Zhou Keke wants to find all the fakes, study them carefully, learn from their mistakes, and then personally put an end to them!

Chen Zhigang had just come out of the bathroom, his hair still wet, when the girl called out to him.

"Uncle Chen Zhi, come quickly and help your niece!"

"What's wrong?"

"I still can't tell what's in these goods."

“Okay, wait while I blow-dry my hair,” Chen Zhi said.

Zhou Keke jumped up immediately: "I'll blow it for you!"

This is called labor exchange.

Lin Yu got tired of sitting and designing blueprints, so she took off her glasses and went for a walk. She saw the two of them getting along intimately like siblings, and she couldn't help but smile warmly.

She turned around, peeled some fruit, cut it up, arranged it on a plate, quietly placed it on the table, and went back to her work.

The whooshing sound stopped quickly.

Chen Zhi has short hair and dries it quickly.

Next comes the identification process.

In Chen Zhi's opinion, Zhou Keke wasn't actually that bad.

Because these antiques are very well made, and some of them are even old objects from the past, but they lack the patterns that evolved from ancient structures, they are not high-grade and cannot fetch a high price, so they had someone add some patterns to them.

The person who wrote the document was also a card maker, and quite professional at that, clearly having some understanding of ancient structures.

This type of imitation is so convincing that even Zhou Keke's professional teacher might not be able to tell the difference.

Chen Zhi was able to find the flaws in the Moon Crown Card Formation entirely because he was familiar enough with the ancient structure.

"This is fake."

"That one too..."

"And this bottle."

Before long, Chen Zhi selected more than twenty undisputed new items from hundreds of antiques.

Fortunately, these items were not expensive to acquire, so although Zhou Keke was heartbroken, she could barely afford them.

"Brother Chen, wait a moment... take another look at this for me."

The girl ran back to her bedroom and rummaged through a drawer, pulling out a small silver stone.

It's about half the size of a palm, oddly shaped, and you can tell at a glance that it's all-natural.

Chen Zhi took it with a puzzled look.

It feels cool to the touch and has a slightly gritty texture.

"Isn't this ore?"

As a veteran miner, Chen Zhi was all too familiar with the feel of it, and couldn't help but ask the girl, "Are ores considered antiques?"

He must have a lot in his bag.

He brought the stones he casually picked up when he went down the well to Tianhengjing as medals.

“The ore doesn’t count,” Zhou Keke said. “It’s just that when I bought this stone, the seller said it was an ancient mineral from a northern mining area, more than ten times older than ordinary minerals. I tried to analyze it with optically determined light, but it didn’t work.”

"Later, it was taken to the laboratory and, with the help of more specialized instruments, it was determined that it was formed 100 million years ago."

Chen Zhi was taken aback: "So long?"

One hundred million years—that's the era of source cards, where there's practically no historical record.

Chen Zhi had learned about the Yuanka era during his archaeology class these past few days.

In short, it was an era in which there is still no conclusive evidence to prove that any civilization ever truly existed.

It is also never recognized by international academic institutions.

If you're planning to submit your card experiments or papers for awards, anything involving the phrase "source card era" will essentially disqualify you from winning any awards.

Research and exploration of this period are currently just a niche activity within a small archaeological community, and are not considered mainstream.

Zhou Keke certainly didn't expect to turn their archaeology project around with a stone. She simply wanted Chen Zhi to help her see its value and whether it could be used to make white cards or card ink.

If possible, they could be sold to the artisans who forge white cards to generate revenue.

They liked this type of ore and called it "source ore".

This requires Chen Zhi to use his "eagle eyes".

Minerals also have "patterns".

Given this, Chen Zhi didn't think the stone could fetch much money.

The reason is simple: the internal structure of ores is often incomplete, making it easier to see. If it were truly valuable, it wouldn't have ended up in the hands of that seller, much less have been snatched up by Zhou Keke.

He has never believed in the idea of ​​finding treasures in garbage dumps.

However, reality slapped him in the face.

When Chen Zhizhen concentrated on observing the stone, before its internal patterns had fully emerged, a sense of familiarity, as if he had been with it day and night, had already welled up in his heart.

"This is……"

"tidal?"

It's the tides?!

Chen Zhi looked bewildered.

So much so that he subconsciously looked up at the moon, which was blocked by the ceiling.

How can rocks on land have tidal structures?

Is this a fragment of a meteorite associated with the moon?

Or did he see it wrong?

Because the structure within the stone is too sparse, containing only half a node, Chen Zhi cannot be entirely certain whether it is tidal. Other ancient structures may also contain similar nodes.

He frowned and thought for a while, then remembered something.

On the day he arrived in Tianhengjing, after clearing up the misunderstanding with Zhou Keke, he noticed that the girl had taken out a medical examination report from her bag.

Chen Zhi quickly looked away, after all, it was someone else's private matter, and he shouldn't look at it if he shouldn't.

Now, he has a bold guess.

"cocoa."

"Ok?"

Do you have irregular periods?
