Han Feng was full of curiosity and took out the left leg bone.

This is the left leg bone he took from the skeleton at the three-way intersection some time ago, and he had carefully examined this left leg bone before, but he didn't find anything at all.

Just now, a flash of white light suddenly appeared from it, which was very weird, and it had to make Han Feng cautious.

"That white light is somewhat similar to the white light emitted by the Snow Bone Flower, could it be that there is some origin?!" he muttered to himself.

Han Feng decided to take it into the valley together to see if there were any changes, maybe there would be a surprise.

He had always been vigorous, and immediately stepped into the valley.

The Snow Bone Flower still stood quietly in the center, as if sensing his arrival, the white light emitted suddenly brightened and became more intense.

The spiritual pressure surging like a tide came, and a large area of white light condensed into a wall, stopping Han Feng while constantly eroding towards his eyebrows, trying to break through his soul sea as always.

Han Feng withstood the huge pressure, accompanied by dragons and tigers outside his body, and walked forward step by step, the flames splashed everywhere, and after a while, he went to the fifteen zhang area in the valley.

This was like a forbidden area, and Snow Bone Flower immediately reacted violently, as before, thousands of beams of light turned into ropes, blocking all directions, and imprisoning Han Feng again.

Han Feng raised the left leg bone several times, no matter how he infused the power of the True Yuan and even the soul power, but there was no response, which made him depressed, and at this moment he had to raise the broken sword, and he was about to swing and attack.

At this moment, the left leg bone suddenly lit up, and it also emitted a brilliant white light, and with a pop, it rose into the air, and in the blink of an eye, it was divided into thousands of rays of light, which were connected with the rope of thousands of beams of light of the snow bone flower, forming a net in mid-air, shining brightly.

Han Feng was inexplicably surprised, and lowered his head to look at this left leg bone, only to see that layers of runes appeared on its surface at some point, like golden wires, shining, and shining, echoing with the net in the air, as if he was breathing gently.

Han Feng's eyebrows glowed, and his soul power condensed on this left leg bone, quietly peeking at its runes.

The more he looked at it, the more frightened he became, this rune surpassed all the talismans he had in his hand, even a few seven-grade talismans obtained from other enemies were not comparable, it didn't seem to be the same level thing.

Maybe the five-element rune treasure in his storage ring can be compared to it, or even surpassed.

If you really study it thoroughly, he will definitely be able to benefit a lot!

In fact, with his current soul power cultivation, if he had time and opportunity, he felt that he should be able to transcend the limitations of the soul power realm and successfully draw the five-grade rune.

Therefore, he can understand from the rune on this left leg bone, at least he can see it clearly, otherwise ordinary rune masters will definitely not be able to see the doorway.

He watched with relish, oblivious to the passage of time.

Thankfully, his left leg bone was able to fully absorb Snow Bone's attack, which allowed him to devote himself to his research as if no one else was around.

What's even more amazing is that the rune on the left leg bone flashed and flickered, as if it was breathing, and it seemed to be swallowing something, only to see the light emitted by the snow bone flower in the distance gradually dimming.

I don't know how long later, the snow bone flower snapped, and its bone-like branches suddenly appeared a crack, and the fragments flew, and then the light emitted by its flowers suddenly dimmed, and quickly contracted, and even the rope of thousands of beams of light that burst out of it also dissipated like a light extinguished.

The light of the left leg bone rose slightly, and the rune light was rising, and the rune pattern on it was more than doubled, covering almost half of the area at the top of it, layer upon layer, and at first glance, it made people feel a little dazzled.

Han Feng was overjoyed, and seized the time to infiltrate the soul power to observe and understand the mystery.

Unfortunately, it only lasted a few breaths, and the light of the left leg bone shrank, and all the light shrank, and disappeared in a blink of an eye, and then disappeared along with the runes on it.

Han Feng secretly screamed that it was a pity, but he was helpless, he put it away with a cherished place, looked up and looked around, only to find that the spiritual pressure around him had already dissipated, and the snow bone flower in the center had also turned into a pile of fragments, leaving only a faint light, flickering gently.

Han Feng dispersed the golden dragon and giant tiger outside his body, walked to the front of the snow bone flower, and reached out, but as soon as he touched one of the fragments, it immediately turned to ashes, and then dissipated, leaving nothing left.

It seemed to be disturbed, even if it was extremely slight, and the rest of the snow bone flower fragments were annihilated one after another, completely disappearing, and there was nothing left.

Han Feng's eyes flashed slightly, and he muttered secretly: "What the hell is this, it really doesn't look like a living object!"

He did not leave the valley, but sat down cross-legged, took out the rune paper and pen and ink from the storage ring, unfolded a piece of rune paper, dipped the pen in ink, and immediately drew the rune on the rune paper.

His technique is still extremely smooth, like flowing water, and in the blink of an eye, he draws a four-grade talisman.

Then he drew the next one, without stopping, very quickly.

In a short time, and in just a cup of tea, he drew forty or fifty four-rank talismans, which had already been stacked in the open space to his left, and the rune light flickered, illuminating the entire valley.

At this moment, he stopped, held the talisman pen in his hand, and suddenly closed his eyes, as if thinking about something.

After a few breaths, he opened his eyes suddenly, a gleam flashed in his eyes, with a wave of his left hand, a piece of rune paper spread out, he dipped the ink and put the pen, the rune pattern was like a road, instantly formed, between the twists and turns, there were more and more rune roads, but his speed was getting slower and slower, it seemed to be under great resistance, several pauses, if it weren't for his perseverance, he would have given up.

With such a difficult drawing, it is obvious that this grade is not low, it is the five-grade talisman!

Han Feng just thought that after he felt the rune on the left leg bone, he struck while the iron was hot, and maybe he could draw a five-grade rune in one fell swoop.

However, he hadn't drawn a talisman for a while, so he opened the way with a four-grade talisman first, so that he could regain his senses, and after he got his hands on it, he would draw a five-grade talisman, maybe the success rate would be higher.

But the reality is that the difficulty of the five-grade talisman is beyond his imagination, like a mountain in front of him, making him obstructed everywhere, and at this moment, his right hand is trembling slightly.

He gritted his teeth and persevered, advancing a little more smoothly, and it was only an inch long before the last rune was finished.

But at this moment, a trace of red light suddenly appeared on one of the runes on the left, spreading out suddenly, burning its entire rune paper and dispersing with the wind.

Han Feng was a little helpless, sighed, and had to take out a piece of rune paper again and continue to draw with his head down.
