Su Peng's gaze fell on the jujube tree in the courtyard.

The first time he came to Carpenter Cao's house, he watered the jujube trees.

The second time, he was plucking off the yellow leaves of the jujube tree.

The third time, he lay down in an easy chair and drank to himself in front of the date tree.

Fourth ......

These scenes kept overlapping in Su Peng's mind, and there was no reason for this Cao carpenter to particularly like jujube trees, if he had to say a reason......

Su Peng slowly walked towards the jujube tree, this tree is not too tall, and the growth is not very good, on the trunk, there are two or three abnormal protruding wood bumps.

Caressing the jujube tree with the harvest, Su Peng thought that if he was a carpenter Cao, he really hid 'that thing' near the jujube tree...... It is unlikely to be underground, hiding underground is the same as hiding in any underground, there is no difference, and Carpenter Cao's attention is obviously on this jujube tree.

Thinking about it, Su Peng's harvest gently stroked the three protruding wooden bumps on the jujube tree......

……

"Click, click!"

The sound of an axe chopping firewood sounded, and Su Peng had already taken out the tools from Carpenter Cao's house, and at this time he was holding an axe in his hand and was chopping the wooden bumps that protruded from the jujube tree.

He'd already cut one from the bottom up, chopped it up and found that there was nothing in it, and now he's chopping a second.

"Click!" A voice sounded, and the lump of wood was also cut off from the trunk of the jujube tree by Su Peng.

When this piece of wooden lump fell, Su Peng intuitively felt that something might be here.

Using an axe to chop the wood lumps that had been chopped down, Su Peng suddenly felt that his axe seemed to have hit something hard.

Peeling off the sparse wood next to him, Su Peng saw that inside this piece of wood, there was something like a black iron plate.

"That's it!"

Su Peng thought in his heart, took out this iron card, looked at it, and saw that this iron card was not too big, three centimeters wide and four centimeters long, and the whole body seemed to be made of black metal, and the weight of the pick up was also like metal, but on the metal surface, there was a layer of wood like a texture.

Seeing that this texture was more familiar, Su Peng glanced at the jujube tree he had split, and it was very close to the texture similar to the annual rings in the jujube tree.

"The material of this iron plate is really special, it has been grown by the texture of the wood...... Su Peng thought in his heart, looked at the other side of the iron plate, but found that on this iron plate, four words were written in ancient seals!

"Gold, wood, water and fire".

On the iron plate, the words written on these four ancient seals are impressive!

"Wood and water? Is it the Five Elements? Su Peng thought in his heart, but denied it, the place of the iron card is not too big, but you can also add the word 'soil', and there are only four words on it.

Su Peng thought about the meaning of these four words in his mind, and when he thought about it, a flash of inspiration suddenly appeared in his mind!

"Wait...... Gold may refer to the material of the iron plate itself, which itself seems to be made of metal...... As for the wooden ...... This iron plaque is definitely put in the jujube tree, and it is infected with this wood-like texture, as if it is metal wood, not carved a long time ago, otherwise it can't be so consistent with the texture on the jujube tree, so, this gold, wood, water and fire, is it saying that on this iron plate, after the four elements of gold, wood, water and fire are fused, what will happen? ”

Su Peng thought in his heart, and then immediately thought that the reason why Carpenter Cao hid this iron plate in the jujube tree was not necessarily just because it was hidden, perhaps Carpenter Cao also guessed the meaning of the so-called 'wood' of gold, wood, water and fire, so he hid it in the tree.

"Quite possibly...... So what is fire? Is it burned in the fire? Su Peng thought in his heart, in fact, he didn't realize that Carpenter Cao's research on the iron plate was only preliminary, and he didn't expect that what he was thinking about was that this iron card was of another meaning.

However, Su Peng didn't know about this, and he suddenly couldn't wait to do an experiment to see what effect burning this iron plate with fire had.

He walked into Carpenter Cao's house, Carpenter Cao's family was quite wealthy in the village, there was no shortage of anything, even the tools of life, there were firewood and charcoal, Su Peng found some stones, surrounded a fire at the door of Carpenter Cao, and then lit the firewood and charcoal, and then found a carpenter's tool with a handle, wrapped the handle with a strip of cloth, sandwiched the iron piece, and burned it in the fire!

Slowly, Su Peng noticed some changes, and saw that this black piece of iron slowly changed color during the burning process...... But instead of turning normal red, it's ...... Slowly turning purple!

Su Peng could notice that after the color of the iron sheet turned purple, flame-like textures appeared on the surface of the iron sheets, and those wood-like textures did not disappear.

"Looks like I'm on the right track!" When Su Peng saw it, he was overjoyed and continued to heat the iron sheet.

After a long while, Su Peng saw that the color and texture of the iron piece no longer changed, and he knew in his heart that the promoting effect of 'fire' had been achieved.

"All that's left is water...... The so-called water will not be so troublesome, it may be put in the water. ”

Su Peng thought in his heart, and the big water tank of Cao's carpenter's house in the room was still filled with water, so he used a carpenter's tool to hold this piece of iron that burned into a transparent purple, like a transparent jade, and walked into the room.

Opening the large water tank of Carpenter Cao's house, Su Peng put this piece of iron that was burned into the color of purple jade, and the iron piece with the texture of flame and wood into the water tank, and suddenly, Su Peng felt a strangeness!

The piece of iron that was burned into the shape of purple jade did not make the sound of 'tearing, tearing, pulling' the hot metal when it met the water, and even, it didn't want to sink at all, but with a kind of buoyancy, it seemed to be able to float on the water!

Su Peng felt very incredible, the density of this iron piece was definitely more than water, but now that it was burned, it could actually float on the water? What is this force?

However, Su Peng also cooperated with the carpenter's tool that was holding the iron sheet, and watched the purple jade-like iron piece float on the water, only to see that the water in the water tank was gradually decreasing, but in the water tank, a light like an aurora spread out!

Su Peng was stunned, he looked at the inside of this water tank, only to see that the aurora-like light was permeated, and after gushing out of the water tank, it did not dissipate, or fell to the ground, but a light curtain like a movie appeared in the air, in the light curtain, a man in brocade clothes who couldn't see his face clearly, holding a flying knife in his hand, seemed to be using some martial arts!

At the same time, beside this man, thousands of official scripts began to appear, and Su Peng suddenly fell into a mysterious feeling, as if he had participated in the Wild Ball Boxing puppet at the beginning.

"You're learning martial arts! Fengyun Yidao belongs to special martial arts, there is no martial arts experience requirement, comprehension is required: fourteen, perception is required: fourteen, you have not met the requirements for enlightenment...... I can't ...... enlightenment."

Su Peng felt that although he clearly saw that he couldn't see his face clearly in the light curtain in front of him, only about one-third of the scaled down version of the ordinary man was demonstrating the flying knife method, and there was also a mental method cultivation cheats next to him, but he just couldn't see it clearly, and after reading it, he would forget it in his mind.

"Reminder, this token can only store information once, after three minutes, this information will be automatically destroyed, and the token will become an ordinary token."

The sound of prompts sounded in Su Peng's ears, and Su Peng was even more anxious in his heart, he finally encountered an adventure, could he just miss such a secret book that might be a peerless martial arts?

Su Peng was ruthless, and suddenly saw that Su Peng's pupils suddenly spread out like dilated pupils, and in his eyes, a strange light continued to flash.

This...... It is Su Peng's own special skill that affects memory!

Su Peng has about a forty MB biological hard disk-like tissue in his brain, which can usually store some text data, but Su Peng rarely uses him 100% to record the impact of what he sees, and at best uses him to extract some video data.

Because, using this special skill at full capacity, although it may not be like that every time, it is at least half possible, which will make Su Peng have a splitting headache within an hour.

However, now that such an adventure is in front of him, Su Peng can't care about these anymore, and this skill in his mind is fully opened!

And Su Peng's ears sounded with a special prompt sound.

"Tips...... Prompt...... The character's brain waves undergo bizarre changes...... Added unknown skill ...... Unknown skills are designated as 'Memory'...... The character uses the 'memory' skill to forcibly record the special martial art 'Wind and Clouds'...... The storm has been recorded......"

……

……

When Su Peng regained consciousness, he found that he was still in Carpenter Cao's house, but the scene in front of him like a movie light curtain had disappeared.

Touching his head, it was not very painful, Su Peng said luckily, he didn't seem to have a headache side effects this time.

Glancing at the water tank, Su Peng was surprised to find that the entire tank of water had disappeared, and the iron plate was lying under the water tank at this time, and the purple flame texture and wood texture had disappeared, just like an ordinary iron plate.

Su Peng stretched out his hand and took out the iron card, and then remembered the secret book of the special martial arts 'Fengyun One Sword' that appeared.

Su Peng opened the character panel and opened the skill column, but was surprised to find that ......
