Han Feng thought about the countermeasures carefully, thought about it, and only by practicing more could he overcome the environment here, and there was no other way.

He simply calmed down and devoted himself to condensing the six-grade talisman out of thin air, and time passed in a hurry, and ten hours passed quickly.

Han Feng has been drawing six-grade runes all the time, although most of them are mainly failures, but occasionally he can succeed, which makes him more confident, continue to practice, capture that kind of successful qi, hone the technique of using soul power, keep trying, keep reviewing, and finally after three days, he will condense the success rate of the six-grade rune out of thin air at 100%!

The reason why he can be so fast has a lot to do with the nine years he has been in that mysterious little world in the remnant talisman, it is definitely a lot of accumulation, and after practicing hard for a few days at this moment, the effect is very obvious.

After a short rest, he began to devote himself to the matter of drawing the seven-rank talisman in the air again, forgetting to sleep and eating, completely forgetting himself, and practicing day and night.

This time, it took a full seven days for him to achieve a perfect success rate in drawing the seven-rank rune in the air.

At this moment, he rarely showed a smile, although his face was a little pale from overwork.

He sat down cross-legged, closed his eyes and recuperated for three hours, then stood up again, took out seven high-grade spirit stones as if racing against time, and began refining the seven-star sword formation again.

It didn't take long, and suddenly there was a loud "boom", and three spirit stones still collapsed, and the burst of spiritual energy impact swept away the rest of the spirit stones, causing a huge storm, which came too suddenly, almost drowning Han Feng.

Han Feng's face sank like water, and with a casual flick of his sleeves, the turmoil was suppressed, and the surroundings became light, as if nothing had appeared.

His brows furrowed, and he was stunned on the spot for a moment, as if he couldn't figure out what the problem was.

He calmed down, analyzed the reasons for the failure one by one, and finally after careful elimination, he located the reason to the spirit stone itself, perhaps the spiritual energy inside the high-grade spirit stone was not pure enough to cause it to shatter!

He gritted his teeth and decisively took out seven top-grade spirit stones, which is a big deal, you must know that one top-grade spirit stone is equivalent to seven million lower-grade spirit stones, and even in normal transactions, seven million spirit stones cannot be exchanged for seven top-grade spirit stones at all, ten million is enough, and some low-level monks will not be able to obtain such wealth in their lifetime.

"I can't bear to let the child trap the wolf, fight!" Han Feng's gaze was certain, and he immediately began to release his soul power to pull these seven top-grade spirit stones into the air, surrounding him.

The light at the center of his eyebrows flickered, and colored light continued to flow, just seven wisps in total, ready to land on the seven top-grade spirit stones without mishap, silently inscribed the rune path.

In less than a quarter of an hour, half of his rune path was successfully completed, and there was no more shattering of the spirit stone, which calmed his heart a little.

Time passed slowly, and after less than a stick of incense, he finally completed the drawing of all the runes on the seven top-grade spirit stones, and it was at the same time, without the slightest separation, otherwise it would inevitably lead to bad results.

At this moment, he had to activate the runes on each of the best spirit stones, invoke their own spiritual energy, form a formation bridge, and connect with each other, otherwise he would not be able to form a formation.

And this is the most difficult part, the slightest change will be completely scrapped, and all the best spirit stones will have to explode, it's like dancing on a tightrope!

Han Feng secretly took a breath, breathed a little, first volleyed those top-grade spirit stones into a circle and placed them in a circle, and then began to concentrate on activating the runes on each top-grade spirit stone.

Suddenly, seven top-grade spirit stones appeared at the same time, with different colors, red and blue, yellow and white, colorful, gorgeous and dazzling.

Han Feng carefully guided these brilliances out, slowly guiding them to the top-grade spirit stones that were close to each other, and soon the brilliance of different colors touched each other.

At this moment, after the brilliance of the two top-grade spirit stones on the left side touched each other, they suddenly exploded, as if water and fire were incompatible, making a sneering sound, and finally annihilated together, setting off a huge storm, like a storm, which directly caused the rudiments of the entire formation to collapse.

There was a loud "boom", and all the seven top-grade spirit stones burst, pouring out terrifying power, fusing with each other, agitating, and shocking Han Feng in an instant.

Han Feng rushed into the dense forest, I don't know how many big trees he smashed, and flew out more than 100 zhang before he stabilized his figure.

His monkey head was sweet, and he involuntarily spat out a mouthful of blood, and his chest was even blackened by that energy, but fortunately, he ran the Alchemy Vajra Technique in time to resist, so he didn't suffer a heavy blow.

However, he was not surprised, his eyes were shining and he looked ahead, the place where he had stood before had become a ruin, and a deep pit of one hundred and seventy or eighty zhang in the center had been blown out, like a sinkhole, and like the huge mouth of a fierce beast roaring towards the sky.

"This power is really strong!" Han Feng muttered secretly, looking forward to the moment when this formation succeeded, he believed that he would definitely be able to break this prohibition on the top.

What made him even more excited was that he had another killer feature after that, and it was really thanks to Long Min who gave him such a secret book by mistake, and no matter how many spirit stones he gave him, he couldn't get it.

Han Feng calmed down, took out a pill and took it, and then reviewed the reason for the failure just now.

In fact, it is also very simple, it is nothing more than the inconsistency of the attributes of the seven best spirit stones, originally he thought that under the traction of the rune, even if the attributes are inconsistent, as long as they are all aura, they should all be able to be fused together, who would think that in an instant, it was like a fire burning oil, and it exploded completely, it was like a thunderbolt on a sunny day, and it almost didn't scare people to death.

Han Feng quickly refined the elixir, his breath gradually recovered, and he silently breathed again, and then released his soul power to infiltrate into the storage ring, and after carefully rummaging through it, he finally found seven top-grade spirit stones with the same attributes, and they were all metallic.

He was able to get these top-grade spirit stones so easily, and thanks to Ran Lintian's storage ring, it seemed to have something to do with the fact that he was a disciple of the Ten Thousand Swords Sect, most of the spirit stones were metallic, and five of them were all taken from him.

However, if he couldn't succeed this time, then he would no longer be able to gather the other seven metallic top-grade spirit stones, so his pressure couldn't help but increase.

He took a deep breath and released his soul power to pull these seven top-grade spirit stones to float up, directly in the right direction, turning into a circle and wrapping around his chest.

He began to draw his soul power out, and the colored light flickered, carefully and meticulously inscribed the rune path, and it was imprinted on these seven superb spirit stones in a flash.
