Entering the secret cave, at first, You Jiecao only felt dim, and after staying on the ground for a second, his vision gradually became clearer, and he saw a stone platform in front of him, and a box-like thing was placed on the stone platform.

Other than that, in the secret cave, there is nothing else to be seen.

Looking at the stone platform, You Jiecao thought: "This stone platform is casually placed here, there must be a mechanism here, but I don't know what this mechanism is." ”

When You Jie Cao thought about it, Wu Wuyan said: "There is no mechanism, you can walk over with confidence, because only acquaintances know the position of this big array." Wu Wu hesitated for a while, and then continued: "This big array, only me and Tianjizi know, even the charm is unknown, I think he generally won't talk about it, because there is no treasure here, only a broken key." ”

Hearing Wu Wu's words, 'When there is no mechanism', You Jiecao has already walked towards the box-like thing, and as he stayed longer, You Jiecao's eyes have become dim, and he saw a boxy box in front of him.

In the dark, the color of the box is difficult to distinguish, but it looks very old-fashioned, and it seems to be a certain age item.

Reaching out to touch the box, I felt that my hand was cold, as if it was made of steel and made of rock.

Gazing in, I saw that there was a lock on the box, the box was interlocked up and down, and on the edge, there were two small rings extended, and the rings were fastened with a delicate small lock.

You Jiecao stretched out his hand to pick up the box, but he felt that the box was extremely heavy, and he was angry, and when he lifted the box, he felt a little lacking in energy.

"Wu Wu, can the lock of this box be smashed open?" If You Jiecao is the only one here, I am afraid that he has been forced to open the lock, where can he ask so much.

"If you can, you can try. Wu Wu said.

You Jiecao looked at this small lock, and secretly thought: "Is there any mystery in this small lock, wait for me to try it." ”

Thinking of it at the same time, You Jie Cao put the box back in its place, took out the demon killing knife, only talked about the demon killing knife rose to Lv4, aimed at the head, and secretly shouted in his heart, a knife was cut down with the momentum of wind and thunder, only to hear the sound of "Zheng", You Jie Cao Hu's head hurt, and then look at the small lock, intact and unharmed.

Seeing that Youjie Cao was deflated, Wu Wu was both proud and sad, paused for a few seconds, and said: "This lock and box, there is a great origin, when a Venus outside the sky fell steeply, the grass and trees within a hundred miles of land, steamed dry and burned, leaving only a piece of black stone, Tianjizi saw the extraordinary black stone, with this black stone, to create this box of a lock." ”

"Then how to open this box?" You Jie Cao thought, Wu Wu knew the origin of this box, and he must know how to open the box.

"Can you see a small hole in that little lock?" Wu Wu said, "That little hole is very secret, you have to look closely, otherwise you won't be able to find it." ”

You Jiecao immediately touched the small lock with his hand, and it was half loud, and there was no small hole, but Wu Wu's words were rarely wrong, and he could only continue to grope at the moment.

Seeing You Jiecao's clumsy appearance, Wu Wu sighed and said, "The reason why people are smarter than animals is that it all depends on one mind, don't you light the fire?"

You Jiecao looked embarrassed, touched his nose, took out the fire fold, and after igniting it, he saw a small hole in the small lock, looking at this small hole, You Jiecao couldn't help but make trouble.

You Jiecao thought to himself: "Such a small hole, is it related to opening the box?"

You Jie Cao thought about it at the same time, Wu Wu immediately said: "By the way, this small hole is related to whether the box can be opened, if I tell you that this box has no key, do you believe it or not?"

Without letting You Jiecao speak, Wu Wu said: "But the box without a key has a lock, and the way to open this box is extremely simple, that is, to pass an object as thin as a small hole through the small hole, and the box will open naturally." Wu Wu sighed, his words were excited and enthusiastic, and said: "This is where Tianjizi is smart, if ordinary people look at such a box, they must use all their strength to forcibly open it, but if that, he will not be able to open it for the rest of his life, because the black stone outside the sky can absorb aura, and its hardness has exceeded ordinary people." ”

When You Jiecao heard what Wu Wu said, he couldn't help but feel that Tianjizi was really wise, but in his heart, he still thought that he was better than Tianjizi.

In the firelight, the thin thing as a fly's head passed through the small hole, only to hear a soft sound, a thing, falling off the box, "click", fell on the ground, this thing is the box.

You Jiecao looked at the box that had been opened at any time, and thought: "What is this heavenly machine key, so mysterious." ”

Open the box casually, just touch the box with your hand, only to hear the sound of "boom", the stone wall shook by itself, and You Jie Cao, who was in the secret cave, only felt that the cave mountain was shaking, and was surprised, and couldn't help but feel scared, and hurriedly asked: "Did you touch any mechanism?"

"Where did the mechanism come from, the Earth Crack Wave Array is already a very powerful mechanism, there is no need to set up any mechanism here, I think someone must be bombarding the stone wall!"

Hearing what Wu Wu said, You Jiecao said secretly: "Could it be that some monster is coming?"

Thinking of this, I can't help but secretly worry about the beauty of flowers, pick up the box, and go out!
