"Whew!"

In the next moment, a sword light the size of a hundred zhang shot out, soaring into the sky, slashing towards the layer of earthy yellow light net laid by Long Min.

This sword fully consumed nearly eighty percent of Han Feng's True Yuan power, and the power was agitated, accompanied by a violent wind, shaking the heavens and the earth.

"Boom!"

A shocking sound spread, and the earthy yellow light net burst out with a dazzling light, blocking the broken sword ray, but it only lasted for a short time, and then it sneered, the light dissipated, and the light net broke one after another, and it completely collapsed after a while, and was rushed away by the broken sword ray.

And the remnants of the broken sword still existed, and it continued to hit the blue sky, but just as it was approaching, the light curtain with golden runes appeared again, unbreakably blocking the broken sword, and a series of ripples appeared on its surface, layer upon layer, colorful.

After a long time, the Broken Sword Ray vanished, and the golden light curtain slowly regained its calmness and returned to nothingness.

Han Feng didn't continue to attack, he knew that with his current strength, it was not enough to break through this golden light curtain alone, even with the help of that three-legged tripod, after all, he was the only one, and he couldn't use the two tricks at the same time, so it would be difficult to exert his power to the strongest state.

He put away the broken sword, recovered the power of the true yuan a little, and thought silently for a while, but decided to complete the talisman array in the secret book according to the original plan.

Originally, he thought that if Long Min didn't have any classics about the formation for him, he wanted to use her power to urge the broken sword together, maybe he could also break the prohibition and escape.

But now it seems that he alone will not be able to succeed. As for his Five Elements Seal Supreme Strength state, that power was actually similar to the Broken Sword Ray he had just chopped, and it didn't have the sharpness of the Broken Sword Ray, so it would be even more difficult to break through the blockade of this golden light curtain.

Having said that, after thinking about it, he decided to condense the black fire seal of the ellipsoidal state, and after ten breaths, in the black light, this ellipsoid rushed to the sky, and once again hit the golden light curtain, causing its runes to flash layer by layer, colliding with fierce firelight, red and black, looking extremely weird.

Not long after, the black fire seal of the ellipsoidal state exploded violently, and in the rumbling sound, the golden light curtain was distorted, but it just failed to break through, and it didn't even cause a crack, which was much worse than the state in which he and Long Min joined forces before.

Han Feng sighed slightly, with today's plan, he can only choose the way of the rune array, and he will definitely do something.

The rune array is many times more complicated than the rune, and although the basic thing is still the rune, it is much more difficult to match various different types of runes together without conflicting with each other.

Han Feng's brows furrowed from time to time, as if he had encountered a lot of puzzles, and sometimes his brows were stretched, showing a happy smile, as if he had comprehended something crucial.

Time passed quickly, and three days and three nights passed.

Han Feng was still sitting cross-legged on the ground, his eyes closed, and he was studying the formation without sleep or food, and the various types of formations in that secret book had been practiced in his soul sea many times.

Before he knew it, another four or five hours passed, he finally opened his eyes, stood up, stretched his limbs, exhaled a long breath of turbidity, and then reached out and gently wiped his hand on the storage ring, and took out seven high-grade spirit stones.

He played carefully for a while, and suddenly pinched the trick with one hand, and as his seal changed, wisps of colorful light began to emerge from his eyebrows, directly sprinkled on the seven high-grade spirit stones on his right hand.

"Huhuhu......"

The seven high-grade spirit stones immediately spun up, hanging in the air, surround him in the shape of a half-moon, and his soul power continued to draw on them, as if he was inscribed with something, but he couldn't see it at all, only a flash of colored light, it disappeared into those spirit stones, and disappeared.

Han Feng drew intently, his face was like an ancient well without waves, and he was very calm.

It didn't take long for three of the seven top-grade spirit stones to snap with a crisp sound, and dense cracks appeared, which exploded in the blink of an eye, and then the extremely rich spiritual energy instantly escaped out, forming an extremely strong shock wave, submerging the remaining four high-grade spirit stones, triggering a chain reaction, bursting one after another, banging.

Han Feng frowned, and with a wave of his hand, he stopped this shock wave without affecting him.

"Could it be that the idea of using spirit stones to refine this seven-star sword formation is wrong?" Han Feng wondered.

In his previous enlightenment, there was a seven-star sword array on that secret book, once formed, it could condense seven spiritual energy giant swords, which was enough to split mountains and seas, and the power was so great that it was no less than the seven consecutive attacks of the old monster of Jiedan, and I believe that it could break this prohibition on the top.

However, the cheats clearly state that there must be the level of a seven-grade talisman master, and there must be seven special spiritual objects as a carrier to be able to refine successfully, and it must be drawn on these seven spiritual objects simultaneously, otherwise it will not be possible to form a formation.

Han Feng thought about it and found that this formation was suitable, although it was not the strongest, but relatively speaking, it was the most suitable for him, so there was the scene just now.

As for the seven special spiritual objects, in his mind, there was nothing more suitable than the spirit stone, after all, the spirit stone is also natural, and the abundant spiritual energy contained in it is enough to support the internal friction of the formation, and it also saves the need for another configuration of spirit stones, which can be described as killing two birds with one stone.

It's just a pity that he didn't completely grasp the mystery of this formation, and he still has a long way to go from success. In his feelings, this formation has extremely high requirements for the adjustment of soul power, and if he is not careful, it will fall short.

Han Feng naturally didn't get discouraged, and silently reviewed it for a while, and instead of continuing to refine this formation, he began to release his soul power and draw a five-grade rune out of thin air.

He felt that since he had a problem with his soul power manipulation ability, it would be a better choice to lay a good foundation first and not rush it.

He was already familiar with drawing the five-grade rune out of thin air, and with a flash of soul power, it was condensed, and a fire snake talisman emerged, and with the movement of his mind, the whole talisman began to spontaneously combust, and the monstrous aura gathered over, and in the blink of an eye, it conjured up a fire snake dozens of zhang long, exuding an extremely terrifying aura.

Han Feng naturally didn't pay attention to it, and with a casual slap, he scattered it.

Next, he began to draw the six-rank talisman out of thin air, and he failed at first a few times, forcing him to pause and ponder why.

In his mind, perhaps the aura here was not as pure as the mysterious little world in the remnant talisman, so it was very easy to cause the rune path condensed out of thin air to collapse.
