Li Yan picked up a piece of paper scattered on the ground again and looked at it.

On top of it is also a card with the special effect of the source card, Water Bomb.

If the user has activated the Water Magic Mastery skill, the card will temporarily become Ice Spear.

Are all cards that change depending on the activation of the card master's skills?

Just like Poppy?

Li Yan looked at the paper in his hand and suddenly remembered that he hadn't summoned Bobby for more than a day.

Then Li Yan consumed 1 point of the power of the royal card and summoned Bobby.

Because of the new environment, Poppy seemed to be very cheerful, jumping and jumping on Li Yan's head, and then jumping on top of the flash girl's head.

Li Yan carefully explored this underground research institute under the light of the flash girl.

First of all, I don't seem to notice that there is a door, so it seems that there is no need to worry about danger for the time being.

On the way to find the door, Li Yan found a mural.

The mural appears to have been hastily drawn, but it is beautifully carved directly into the metal wall.

Li Yan turned around and asked the flash girl to come closer, and under the light of the flash girl, Li Yan clearly saw the content of this mural.

Judging from the outline of the mural, the scene on it seems to be the old city of this Star Energy City.

In the mural, high in the sky of this old city, a handsome man in fluttering clothes stands above the void.

The man stood proudly in the world, holding his hands in his hands, and in front of him, a black card floated.

And beneath him, the giant city seemed to be crumbling inch by inch, and countless high-rise buildings were collapsing.

Li Yan looked at the mural suspiciously.

In the entire mural, this black card is the most conspicuous.

Because of the entire mural carved into the wall, only this black card is colored.

Could this be the reason why this old city was abandoned?

Is it because of this black card?

Just because of one card, can the entire old site of Starlight City be reduced to ruins?

Li Yan looked at this black card with some longing, very curious about what kind of card this was.

Then Li Yan was afraid that he had missed any other clues, so he carefully examined the mural.

During the inspection, Li Yan found this man standing alone with his hands in his hands, standing proudly above the void.

On the back of his clothes, there is a swirl pattern.

The pattern of the swirl?

Is there any special purpose in deliberately carving this pattern on the clothes?

Li Yan told the flash girl to come closer, and then Li Yan took a closer look at the mural.

There's nothing else special anymore.

As if thinking of something, Li Yan pulled out a crowbar, moved it backwards, and then slammed it against the wall.

Under Li Yan's full force, there was not even a scratch on this metal wall.

Li Yan changed color again and was able to carve a mural on this wall.

The person who carved the mural was at least a corrugated card master, right?

Then Li Yan summoned three more flash girls, and under their illumination, this underground research institute became very bright.

Li Yan carefully explored this underground research institute, and on each scattered piece of paper, there was a source card with a special effect.

But what made Li Yan very disappointed was that.

I didn't pick up a single card in it.

Generally speaking.

Isn't it time to let yourself pick up the treasure?

After all, this seems to be a hidden underground research institute, and the reason why I was able to get in was because I used random teleportation.

Li Yan explored every corner of this underground research institute one by one, and 4 flash girls stood around him, providing him with plenty of light.

After fully exploring, Li Yan found that there was nothing left in this underground research institute except for the 17 pieces of paper scattered on the ground.

Each of the 17 sheets of paper contains a source card with a special effect.

After Li Yan confirmed that there was nothing left, he was ready to sit down and return to a wave of state first, and then go out.

It's just that as soon as Li Yan sat down, he found that Bobby was bouncing on a strange machine, and he kept Bobbi Bobby barking.

Did Poppy find anything?

With a group of flashing girls, Li Yan came to Bobby's side, and Bobbi jumped on top of Li Yan's head.

After carefully probing the machine again, Li Yan found that there was indeed nothing.

Is it under the machine?

Li Yan chose to believe Bobby, after all, Bobby is so cute.

So Li Yan used all his strength to push away this calm huge machine.

Underneath the machine, there was a scattered piece of paper.

This is a piece of paper gilded around it, and it looks much more precious.

Li Yan picked it up, and after picking it up, Li was the first to appear

If you have this kind of treasure hunt in the future, you must always bring Bobby!

Li Yan thought as he couldn't wait to look at the small line of text under the gold-plated paper.

"A strange source card, a skill that has never been heard of, and according to the special effects of the source card, the development value is extremely high......"

Li Yan read this line of text thoughtfully as he watched.

This line of text is written, not typed like other papers.

On the front of this golden paper there is only this line of text, and nothing else.

Then Li Yan looked at the back of the paper again.

The handwriting on the back of the paper is also written with an ordinary pen.

"These two cards have a lot to do with them, and we can't get involved in them, so don't study them anymore, and it's better not to have anything to do with them......"

Li Yan frowned slightly, showing a thoughtful look, and read out the words on the paper again.

Judging from the handwriting, this paragraph is obviously from the same person as the one just now.

But the person who wrote this passage clearly wrote it with trembling hands.

Even the card master's hands tremble?

On the back of the gilded paper, there is only one sentence.

But the message of this sentence is a little difficult to digest.

Even this underground research institute specializing in special source cards doesn't dare to touch a card?

Is the Dark Key so dangerous?

Holding the golden paper in his hand, Li Yan read this sentence repeatedly, frowning, not knowing what he was thinking.
