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

When he first came to Cao's house, he watered the jujube tree.

The second time he came, he was removing the yellow leaves from the jujube tree.

The third time he came, he lay on an easy chair and drank by himself at the jujube tree.

The fourth time...

These scenes keep overlapping in Su Peng's mind. There is no reason for Carpenter Cao to like the jujube tree especially, if he has to say the reason...

Su Peng slowly walked towards the jujube tree. The tree was not too tall and it was not very good. There were two or three unusually protruding lumps of wood on the trunk.

Using the harvest to caress the jujube tree, Su Peng thought that if he was Carpenter Cao and really hid only the "that thing" near the jujube tree... the possibility of underground is not high. Hiding it underground is the same as hiding it underground, and there is no difference. Carpenter Cao's attention is obviously on this jujube tree.

Thinking of Su Peng's harvest, he gently stroked the three protruding lumps of wood on the jujube tree...

...

"Crack, crack!"

The sound of an axe chopping firewood sounded. Su Peng had already taken out the tools from Carpenter Cao's home. At this time, he was holding an axe in his hand and cutting the bumps of wood that were protruding on the jujube tree.

He had chopped down one from bottom to top, and found that there was nothing inside. Now he was cutting down the second one.

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

When this lump of wood fell, Su Peng felt intuitively that the thing might be here.

With an axe, Su Peng suddenly felt that his axe seemed to have hit something hard.

Peel the rotten wood next to it, and Su Peng saw that there was a black iron plate-like thing inside this piece of wood.

"That's it!"

Su Peng thought to himself that he took out the iron plate and looked at it. He saw that the iron plate was not too big, three centimeters wide and four centimeters long. The whole body looked like black metal. The weight he picked up was also like metal, but on the surface of the metal, there was actually a layer of wood texture.

Seeing that the texture was more familiar, Su Peng took a look at the jujube tree he split, and it turned out to be very close to the texture similar to the annual rings inside the jujube tree.

"The material of this iron plate is really special. It is actually grown up by the texture of the wood..." Su Peng thought to himself, and looked through the other side of the iron plate, but found that four words were written in ancient seal script on this iron plate!

"Gold, wood, water, fire".

On the iron plate, these four characters written in ancient seal script are on it!

"Gold, wood, water and fire? Are the five elements?" Su Peng thought in his heart, but he denied that the iron plate was not too big, but he could also add the word "earth", but there were only four words on it.

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

"Wait... gold may refer to the material of the iron card itself, which itself seems to be made of metal... As for wood... this iron card is definitely placed in the jujube tree and is infected with this wood-like texture, as if it is metal wood, not carved long ago, otherwise it would not be so consistent with the texture on the jujube tree. So, is this gold, wood, water and fire saying that what will happen after the four elements of gold, wood, water and fire are integrated on this iron card?"

Su Peng thought in his mind, and then immediately thought that the reason why Carpenter Cao hid this iron plate in the jujube tree was not necessarily because of its concealment. Perhaps Carpenter Cao also guessed the so-called "wood" of gold, wood, water and fire, so he hid it in the tree.

"It's very likely... So what is fire? Is it burning in the fire?" Su Peng thought to himself. In fact, he didn't realize that Carpenter Cao's research on iron cards was just a preliminary, and he didn't think about where he was thinking. This iron card was of other significance.

However, Su Peng didn't know this. He suddenly couldn't wait to do an experiment and see what the effect of burning the iron plate with fire was.

He walked into the house of Carpenter Cao. Carpenter Cao was still wealthy in the village and had nothing to do. Even the tools of life were firewood and charcoal. Su Peng found some stones, surrounded a fire at the door of Carpenter Cao, then ignited the firewood and charcoal, then found a carpenter's tool with a steel handle, wrapped the handle with a cloth strip, clamped the iron piece, and burned it in the fire!

Slowly, Su Peng discovered some changes, and saw that this black iron sheet slowly changed color during the burning process... but it did not turn into normal red, but... slowly turned into purple!

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

"It seems that I want to be right!" Su Peng was delighted when he saw it and continued to heat up the iron sheets.

After a while, Su Peng saw that the color and texture of the iron sheet no longer changed, and knew in his heart that the promotion effect of "fire" had been achieved.

"What's left is water... The so-called water will not be very troublesome, it may be just put in the water."

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

When Su Peng opened the large water tank of the Cao Woodman's house, he put the iron sheet burned to purple jade color, and the iron sheet with flames and wood texture into the water tank. Su Peng suddenly felt something strange!

The iron sheet burned into the shape of purple jade did not make the sound of the hot metal that was "teared, teared" when it encountered water. It even did not want to sink at all, but carried a buoyancy that seemed to float on the water!

Su Peng felt very incredible. The density of this iron sheet is definitely greater than that of water, but now it is burned and can float on the water surface? What kind of power is this?

However, Su Peng also cooperated to release the carpenter tool with the iron sheets. Seeing the purple jade-like iron sheet floating on the water surface, the water in the water tank gradually decreased. However, in the water tank, a kind of light that was not fog, but like an aurora, spread!

Su Peng was stunned. He stared at the water tank and saw the aurora-like light spread out. After it surged out of the water tank, it did not dissipate or landed on the ground. Instead, a light curtain like a movie appeared in the air. In the light curtain, a man in brocade clothes who could not see clearly was holding a flying knife in his hand, as if he was using some martial arts!

At the same time, thousands of official script characters began to appear around this man, and Su Peng suddenly fell into a mysterious feeling, just like he had learned about the wild ball boxing doll.

"You are comprehending the martial arts "Fengyun Yidao"! Fengyun Yidao is a special martial arts, without the requirements of martial arts experience, requires understanding: fourteen, requires perception: fourteen, you have not met the requirements of comprehending... cannot comprehending..."

Su Peng felt that although he could not see clearly in the light curtain in front of him, only one-third of the reduced version of the man was demonstrating the flying knife method, and there was also a secret to practicing the mental technique next to him, but he just couldn't see it clearly. After reading it, he would forget it in his mind.

"Tip: This token can only store information once. After three minutes, this information will be automatically destroyed and the token will become an ordinary token."

A prompt sounded in Su Peng's ears, and Su Peng felt even more anxious. He finally encountered an adventure himself. Could it be that he missed such an article that might be a secret book of peerless martial arts?

Su Peng made up his mind and suddenly saw Su Peng's pupils suddenly spread out like his pupils, and strange light kept flashing in his eyes.

This... is Su Peng's special skill, which affects memory!

Su Peng had about a 40M biological hard drive-like organization in his mind, which could store some text information, but Su Peng rarely used him to record the impact of his seeing, and at best used him to extract some image information.

Because, although using this special skill at full capacity may not be like this every time, at least half of the possibility will make Su Peng feel a splitting headache within an hour.

However, now that this adventure is right in front of me, Su Peng no longer cares about these things, and the skill in his mind is fully activated!

A special prompt sound rang in Su Peng's ears.

"Tip... Prompt... The character's brain waves have undergone strange changes... The unknown skills are added... The unknown skills are designated as 'memory'... The character uses the 'memory' skill and forcibly record the special martial arts 'Fengyun Yi Dao'... The Fengyun Yi Dao has been recorded..."

...

...

When Su Peng regained his consciousness, he found that he was still in Cao's house, but the scene in front of him, which seemed to be a light curtain on a movie, had disappeared.

It didn't hurt very much after touching his head. Su Peng thought to himself that he didn't seem to have any side effects of a headache this time.

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

Su Peng reached out and took out the iron plate. Only then did he remember the secret of the special martial arts "Fengyun Yidao" that appeared.
