Lin Dong was shocked when he saw the box inside the stone room.

What good things will be there to hide in a box in such a hidden stone room?

Lin Dong took two steps in three steps to approach the box made of brass. The box was about one meter long and half a meter wide and was close to one meter high. "If it was a box of gems, I would have sent it!" Lin Dong thought to himself.

The copper box is well-made, but it is a bit too simple. The huge box is bare and there is not even any decorations.

Lin Dong has read from books that most treasures in secret rooms will be designed. Will this box be placed so suddenly here and there be any danger?

Lin Dong thought to himself, and pressed the button at the same time to activate the phantom beast Kara.

The light flashed, and Kara appeared in the stone chamber. It seemed to be curious about what this place was, and its nose kept sniffing the smell on the ground. Since the last time Wanghailou was in danger, Lin Dong and Kara's relationship has improved a lot. Kara no longer ignored Lin Dong like she used to, but she still maintained her lustful male dog nature.

"Kala, look around and see if there is anything suspicious." Lin Dong said to Kara.

After all, Kara is a semi-intelligent fantasy beast. She can understand Lin Dong's words even though she understands them. It seems that it is not a good job, and she slackened her head and started lazily in the stone room.

Karadong smelled Xisiaosiao wandered around the stone chamber, and finally stopped in front of the copper box, grinning at the copper box, as if he was very afraid of the box.

Lin Dong was shocked, "Fortunately, let Kara explore the way first, otherwise he would be in trouble."

Although he thought so in his heart, Lin Dong was really unwilling to open the box. "Kara, open this box." Lin Dong said, while dancing and gestured.

Kara looked back at Lin Dong, as if saying "Why me?"

Lin Dong said: "You open it and take a look. Anyway, you are the incarnation of energy and will not die."

Kara roared for a long time, suddenly stretched out her front paw and lifted it upwards, lifted the upper cover of the copper box, then jumped in and bite the object inside the box.

To Lin Dong's expectations, there seemed to be no danger in this box.

Lin Dong walked closer and took a closer look.

It turned out that there were only some clothes in the box. Because these clothes were old, they could no longer distinguish the original colors. They were bitten by Kara and became a mess and worthless.

Lin Dong was very disappointed and let Kara tear it around there. He began to observe carefully around other objects in the room.

First, I checked the indoor tables and chairs without any abnormalities.

Then Lin Dong came to the largest stone bed in the room, brushed away the dust on the stone bed with his hands and observed it carefully.

This stone bed is made of a whole piece of rock, three meters long, more than one meter wide and about half a meter high, like a stone coffin.

Lin Dong coughed because of the dust, but Lin Dong did not stop fumble.

Suddenly, his fingertips felt a gap on the stone bed.

Lin Dong was overjoyed.

He took off his coat and ran to the outdoor pool with water, and wiped it hard on the bed.

A moment later, the light that Lin Dong wiped this stone bed was evident.

A square gap appeared in front of Lin Dong.

The gap is located in the middle of the stone bed, the size of a palm. Lin Dong held a sharp knife in his hand and wanted to pry open the gap to see what was inside, but after a long time, the gap was not pried open, and the steel knife wore several gaps.

"What material is this stone bed? It's so hard." Lin Dong murmured in a low voice.

If it cannot be solved by force, will it be like before that you need to find a slot to insert an energy card?

Lin Dong thought to himself that he no longer hesitated and continued to wipe other parts of the stone bed with his coat, looking for slots.

As the saying goes, hard work pays off, Lin Dong found another slot on the side of this stone bed.

It was exactly the same as the two slots I discovered before, Lin Dong was very surprised. He seemed to have seen the room full of gold, silver and treasures.

The third-level energy card is gone, and Lin Dong found a second-level energy card from the card bag and gently inserted it into the slot.

The "pop" card was inserted, and a square dark grid on the stone bed slowly rose.

As the dark grid rose, Lin Dong's eyes became brighter and brighter.

A golden box appeared in front of Lin Dong's eyes.

Lin Dong gently took out the small box and put it in the palm of his hand to play with it.

This is an exquisite box made of gold, but only half the size of a palm, with gorgeous workmanship and carved birds and beasts that are lifelike.

Open this small gold box, inside it is a small card bag made of white rhino leather. The white rhino is known as the best material for making card bags. It is not only waterproof and fire-proof, but also said to ensure the performance of the card without loss.

The card bag is indescribable and gentle, with excellent toughness and incredible weight.

The card bag is simple and exquisite, and the workmanship is as natural as it is formed.

Lin Dong opened the card bag and found that the card bag was divided into two layers, each layer with a card in it, and all of the two cards were black without exception.

In the bimonthly continent, black cards are very rare. This is because if black is used as the main color, it will be extremely difficult to control the color division of pigments. Black is too inclusive and will seize other colors on the card, causing the entire card to lose its due performance.

Lin Dong took a card in his hand, and when he looked at it, he couldn't help but feel shocked. This card actually had a single-layer structure!

In the Bimoon Continent, even first-level cards must use a double-layer structure. I have never heard of a card with a single-layer structure. What card is it that only has one-layer structure?

What's more amazing than this is the structural complexity on the card.

If the most complex structural graphics on the mainland are intelligent structures, the structure on this card is dozens of times more complex than intelligent structures!

Lin Dong was already shocked when he saw the complex intelligent structure as complex as a star. Now the structure on this card completely confused him!

Lin Dong studied painting for more than ten years in his previous life and thought he had a good foundation. He was confident of completing a complex intelligent structure, but the structural complexity of this card has exceeded Lin Dong's imagination!

Lin Dong knew in his heart that with his own skills, he would never be able to draw such complex graphics, and it was impossible.

The same goes for another card.

Extremely sophisticated and complicated single-layer structure, no card name, no maker.

What card is this?

The pigments used in the two cards are golden and silver. Lin Dong can't see the material of the card, but it has a very simple feeling and must have been around for many years.

Lin Dong sat on the stone bed and fell into deep thought. What a weird card!
