Hearing the sound of rubbing, Pang Yuan was shocked and looked down.

A small square piece of iron was found on the surface of the tin box, and its position had changed slightly.

Only then did the boy realize that those seemingly sturdy little iron units could actually move!

This was completely unexpected by Pang Yuan, when observing, the young man saw that the iron box was sealed very tightly, and instinctively meant that these small square iron units were fixed on the surface, and he didn't think about other places, so he subconsciously ignored them.

Until just now, my fingers inadvertently touched the lines on the surface of the iron, causing the position of the iron to change.

The boy was pleasantly surprised to discover that these iron units were not welded to death, but could be flexibly replaced, and the blank square area was set up for this purpose.

"It's interesting that these little iron units can still be moved!"

"This situation must not be unreasonable, it must be necessary, could it be related to the method of untying the tin box?"

With an unexpected discovery, Pang Yuan's heart suddenly became interested, his eyes were full of excitement, and his hands moved the fifteen small square iron units on the surface at will.

The movement of the iron unit was accompanied by a subtle friction and impact sound, and the sound was crisp, which was very pleasant to the ears of the excited teenager at this moment.

As the square iron units moved, a thin cross-shaped groove underneath was revealed, spreading over the entire area, like a simple chessboard.

Pang Yuan pressed his finger on the iron block unit, controlling the direction of its movement, and tried to walk through the iron block units in each position one by one.

With the change of the position of the iron block, the lines on the surface of the entire iron box seem to be more and more chaotic, and it seems to contain some special rules.

Time flies by, and there is no return.

The sun in the sky gradually sank in the west, and the scattered light changed color.

The forest was silent, and the young man sitting cross-legged on the grass was now completely immersed in studying the movement of the iron block, not realizing the passage of time at all, and at the same time ignoring the little changes in the sky.

The soft yellowing sunlight shone on the side of the young man's face on the grass, pulling the strong figure to the old man......

In this square area on the surface of the iron box, only the empty area is redundant, which can be used as a transfer station for the movement of iron units.

As for the remaining fifteen small square iron units, if any one wants to move, one of the square iron units next to it must be moved out of the way to make room for use, and then it can be changed.

In this way, moving one of the small iron units requires many extra steps, and contains a lot of repetitive movements, which is slightly cumbersome, and greatly increases the difficulty of finding the pattern.

Up, down, left and right, in different directions.

Soon after, he tried to move the various square iron units many times, but Pang Yuan did not notice the pattern at all, and the lines on the surface of the iron box seemed even more chaotic, making people completely confused.

Disappointed, the boy sighed, exhaled the turbid breath in his lungs, and kept this sitting posture still, which had taken so long that he felt a little tired at this time.

Rubbing his slightly stiff neck, Pang Yuan stretched his waist and stretched his body.

Raising his head and looking around at his surroundings, the young man saw that the surroundings were still quiet and remote, and the sky above his head was already dark, and it was obvious that it was not early.

"It's so late, I can't imagine that I just tried it, and before I knew it, it took so long. ”

There has been no clear thinking, and in the face of this "stubborn" pitch-black iron box, Pang Yuan felt a little headache, and he was helpless for a while.

Looking at this posture, this tightly sealed and sturdy iron box should be difficult to open for the time being, the young man shook his head helplessly, and decided to put it aside for the time being, not to think about it.

"I don't want to, it's getting late, I have to hurry up and find a place to settle down, I can't rub in this dense forest anymore, find a place to fill my stomach first!"

The dim sky prompted Pang Yuan to make a quick decision in his heart, and made up his mind not to stay long.

Put the iron box that has been in your arms into the package, fortunately, the iron box is not big, plus in the previous escape, most of the wild fruits in the package have fallen, and the place is vacant, and now the boy's package can barely be completely loaded.

Carefully pack the dark mysterious tin box, tie the package tightly in a knot, and carry it on your back.

Pang Yuan got up, walked a few steps barefoot, picked up the boots that had been put aside to dry on the stones, and wanted to put them on.

After a long period of drying, the surface of the boots has dried, but there is still some moisture inside, especially the heel position, and some shallow water.

In a hurry to leave, the boy didn't pay attention to these details, picked up his boots, poured out the accumulated water, and then put them directly on his feet.

After putting on his boots, pulling down his trouser legs, and tying them up one by one, Pang Yuan walked towards the mountain turtle that was suppressed, with a smile on his face.

"You guy is so dishonest when he is pressed by a stone, so come with me!"

"Haha, I've got a good mouth tonight......"

The young man stretched out his hand, removed the stones from the turtle's body, threw them on the grass on the side, and grabbed the old turtle.

The weight on his body was removed at once, and the old turtle was free, ecstatic, and suddenly came to his senses.

The flat, wrinkled turtle head stretched out and its small claws waved, struggling to escape the clutches of the humans in front of it and avoid doom.

"This thing is not honest!

Pang Yuan saw that the turtle was still struggling, and he felt impatient.

Holding down the old turtle with his left hand, waving his right arm, it came up with a punch and hit the turtle's thin back.

The slap-sized irascible turtle was suddenly hit by this heavy blow, almost stunned directly, and in a daze, it almost stopped struggling, and suddenly quieted down.
