Flipping over the gilded paper again, Li Yan looked at the photo of the card called the Golden Key above the Key of Darkness.

This key also made Li Yan very curious, and he actually placed it with the key of darkness.

Is this also a dangerous key?

There is no information on this piece of paper other than two photographs and two paragraphs.

This made Li Yan a little regretful.

I thought I had finally found a clue, but according to the clues, I just knew that the Key to Darkness was a very powerful card.

Carefully put away the gold-plated paper, in order to make up for the regret that he didn't have enough treasure hunting talent, so Li Yan decided to sweep this abandoned research institute again.

Putting Bobby into the hands of the flashing girl behind him, Li Yan directly rolled up his sleeves and continued to lift other machines.

Under Li Yan's unremitting efforts, the entire research institute was turned upside down by Li Yan.

The interior layout has completely changed, and all the machine tables and chairs have been moved out of their original positions.

However, apart from getting another blank piece of paper for ordinary records, Li Yan had no other gains.

Because of the unexpected discovery just now, Li Yan did not give up completely.

He began to bang on the walls and floors again, looking for possible dark rooms or something.

Under Li Yan's beating, Li Yan soon discovered that something was wrong.

That's the wall where the mural is carved, and the back seems to be empty.

Because the sound of knocking with a crowbar is not the same.

Could it be that there is a secret room behind this!?

Fortunately, I didn't end the exploration hastily!

Li Yan was immediately interested.

After suppressing the excitement and curiosity in his heart, Li Yan searched around the mural inch by inch for the possible secret room door opening mechanism.

Under Li Yan's search, Li Yan soon discovered that something was wrong.

That's the wall of this chamber, as if it could be pushed.

It's very heavy, a lot heavier than all those weird instruments, but it does push.

Isn't the door to this secret room locked?

Could it be that the original owner here retreated too quickly, so he forgot to lock the door?

Li Yan immediately got up, used all his strength, and slowly pushed the thick wall inward.

Halfway through, the wall suddenly became much lighter, sliding directly to the right, revealing the chamber within.

In this hidden secret room, there is only a silver metal platform, and on the metal platform are placed two metal boxes, one gold and one black.

The golden metal box is shining magnificently under the light of the glittering girl.

When Li Yan saw the colors of these two boxes, he immediately thought of the photo on the gold-plated paper just now.

The Key to Gold and the Key to Darkness.

Li Yan looked at the two boxes on the platform with some disbelief.

As far as the color of the box goes, it's likely to correspond to the two cards you just saw.

Didn't the people in this group take these two cards with them when they retreated?

Without staying too long, Li Yan walked directly into the secret room and came to the metal platform.

With anticipation of the key to the treacherous darkness, Li Yan reached for the black box.

If the people of this institute did not bring these two cards with them when they retreated......

Then you can touch it yourself!

As for the words on the gold-plated paper just now, Li Yan was also very concerned.

But it's all at hand, so it's impossible to just let them go.

While thinking, Li Yan lifted the black metal box in his hand.

As the card box slowly opened, Li Yan couldn't help but hold his breath and looked intently at the black metal box that was being opened.

After the black metal box was fully opened, Li Yan saw that a silver card was quietly placed inside.

This card is emitting a faint silver glow, which is the source card of a silver card.

And on the card's top of this card, there is an ancient dark black key.

The key has a strange pattern on it, spreading from the end of the key to the middle of the key.

As for the name of this key, it corresponds to the name that Li Yan will see every time he opens the panel.

- The Key to Darkness.

Series skills?

After being consumed?

If you can fuse the skills of the cards, the name is "The Power of Card Convergence".

So your own skills correspond to the power of the card series of skills?

In other words, in addition to the power of your own card convergence, you also have the skill of other card power!?

Li Yan felt a little big, and he found that he seemed to know something terrible.

The people of this underground research institute were obviously forced by some kind of threat of a terrifying existence, so they gave up these two cards.

Even after the old city was abandoned, they did not leave with them.

And this treacherous key, this card that was abandoned by the people of the institute like a snake and scorpion.

The recorded special effects of the source card are also the special effects of the source card that will only be triggered if the power of the card is required.

Li Yan's eyes showed a thoughtful light.

That is, the people of the institute who abandoned these two cards, the existence they feared.

Is it possible that you also have the skill of card power?

In addition to your own power of convergence, there are other skills of card power?

What skills will it be?

Originally, when he saw this card, Li Yan thought that he had gradually cleared the fog, and he would soon get the power to break through his fate.

But after seeing this card, Li Yan realized that he had fallen into a deeper fog.

Why did the site of this Starlight City collapse, why was this special source card underground research institute abandoned, and why did you say that these two cards were inaccessible?

and what Li Yan cares about the most, and what surprises Li Yan the most.

In addition to yourself, it is likely that there are other skills that are the power of the card.
