The Great Demon Divine Mountain is located in the middle, on the top of the Divine Mountain, Fang Yun sits cross-legged, the tip of the Pure Yang Immortal Sword is facing upward, blooming with golden brilliance.

The defensive formation of the Great Demon God Mountain has completely dispersed, but on the top of the mountain, every grass and tree has a Sanskrit sound roaring, and the formation map is manifested, as if there are countless demon gods who are constantly wandering between the magnificent mountains, roaring wantonly.

The thunder of the Nine Heavens was violent, and the Great Demon God Mountain was not afraid at all, driving the array, shaking up the spirit, and preparing to resist hard.

Around the Great Demon God Mountain, which is proud of the sky, is a huge seven-star crystal array, six divine mountains, blooming with different lights and manifesting different powers, echoing the Great Demon God Mountain.

Second only to the Great Demon God Mountain, is the Storm Tiger sits on the ancient holy mountain, this is the barbarian luck condensed huge mountain, the large array on the mountain is vicissitudes and simple, the momentum is heavy, between the array, a barbarian giant bears the mountain to catch the moon, crisscrossing the wilderness, fighting against heaven and earth.

At the top of the immortal mountain, Dong Jiashuai sat concentratingly, his sturdy body has been integrated with the entire immortal mountain, at a glance, it gives people the feeling that this majestic mountain is Dong Jiashuai, above the mountain, there are also formations in the continuous circulation, but carefully observed, each formation shows a mirror image of Dong Jiashuai sitting cross-legged.

At this time, Dong Jiashuai was less playful and more solemn, with low eyebrows and bowed his head, but it gave people a feeling of profundity.

Worry-free Demon Mountain, Demon Spirit Demon Mountain, is another scene, these two Demon Mountains, the demon flames are monstrous, the demon qi is rolling, and the huge demon gods roar wantonly in the formation, eager to try, facing the Heavenly Dao God Thunder, there is no fear.

The Storm Divine Mountain and the Ancient Qingqiu are relatively quiet, and the momentum is also very restrained, but the formation on the mountain is also glorious, and the monks in the mountain are high-spirited, ready to catch the storm and thunder.

The sky was full of thunder, illuminating the earth.

The entire Thunder Hell was plunged into a flickering silvery light.

The void seemed to be torn apart, and the heavens and the earth only had one color, white, and the monks who were slightly weaker in cultivation had already closed their eyes.

The mortals who were still under the protection of the shield had already entered the room, secretly praying, hoping that the monk could defeat the thunder under the leadership of the Great Demon God.

A rumbling sound resounded through the sky.

Under the Seven Great Immortal Mountains, the cores of the seven Yuan Magnets were launched in unison, and a large number of thunderbolts slashed towards the Seven Great Immortal Mountains.

Each immortal mountain was suddenly covered with silver snakes.

The array flickered, the golden light was magnificent, and the silver snake kept shuttling in the golden light, making a piercing sound.

The thunder was hot, colliding on the upper body, and thunder and fire were rubbed in many places.

Some of the mountains were scorched red as blood by the instantaneous high-temperature thunder fire.

However, even if this mountain was about to melt, with the help of the golden rune array, there was not the slightest sign of collapse.

For nearly a thousand years, the seven sacred mountains have been constantly carving formation diagrams on the mountain in accordance with Fang Yun's requirements, layer after layer.

The mountains of the Seven Great Sacred Mountains have actually been smelted more than once.

In the past, even Dong Jiashuai and Storm Tiger didn't know the reason why Fang Yun asked them to engrave the array runes, until today, they finally understood.

It turned out that this was the rhythm of using the power of thunder to temper the seven divine mountains and smelt them into peerless treasures.

The Chel Demon Spirit drove the Demon Yuan, kept pouring into the Demon Mountain, and kept reinforcing the mountain array runes, but there were still some drums in his heart, and I don't know if the little demon cubs below had cut corners, whether they had beaten those cherished refining materials into the mountain according to Boss Fang's intentions, with quality and quantity.

If the little devil cub has greedy ink, he will have to eat and walk away today.

In other words, the demon cubs are bold, but they can do anything.

Before the critical moment of the thunderstorm came, the Chel Demon Spirit was already covered in a cold sweat, and he only prayed that those little guys would be more reliable.

Wave after wave of thunder spilled down.

Bursts of thunder resounded across the sky.

This is Thunder Hell.

To be honest, Fang Yun didn't expect that the momentum of the Seven Great Immortal Cities Thunder Hell would be so vast and terrifying.

The overwhelming divine power is simply irresistible.

In contrast, when Fang Yun broke through the Thunder Hell alone, whether it was the strength of the thunder, the density of the thunder, or the coverage area of the thunder, it was far less powerful than it was now.

The mighty power of the thunder made Fang Yun quite jealous in his heart, and he was extremely palpitating.

The thunder is fierce, I didn't expect it to be so terrifying.

No matter how good his calculations were, Fang Yun didn't dare to say that he would definitely be able to lead the Seven Great Immortal Cities through the Thunder Hell perfectly.

The endless sea of thunder has the power to tear the heavens and the earth.

Once the thunder breaks through the defenses of the Seven Great Immortal Mountains, once the thunder breaks through the defensive cover of the immortal city, under this kind of thunder, those monks and mortals who have weaker cultivation are afraid that they will be wiped out in an instant.

However, now that he had entered the Raging Thunder Prison, it was useless to think about anything, Fang Yun could only drive the Great Desolate Battle Qi of his whole body, bloom with infinite power, and help the Seven Great Immortal Cities survive this peerless difficulty.

After this level, the Seven Great Immortal Cities would inevitably have an earth-shattering transformation, otherwise, the ending would definitely be quite tragic, and Fang Yun would not dare to be sure how many people would die.

The Great Wilderness War was driven by all its might, and the Great Wilderness Battle Intent was sprinkled towards the Seven Great Immortal Cities through the Seven Star Crystal Array.

The Pure Yang Immortal Sword shook slightly, and the strongest stunt in the world had been launched, constantly blessing Fang Yun's Great Wilderness Battle Intent.

The unparalleled fighting spirit shrouded in the Seven Great Immortal Cities, and every monk was boiling with blood, daring to fight with the supreme battle intent of the sky.

Although the thunder is fierce, the monk is not afraid, and on every immortal mountain, there are monks howling, drawing their swords and pointing to the sky, bound to fight with the thunder to the death.

Of course, under the guidance of the powerful monks, these monks constantly injected their true yuan demonic energy into the formations and runes, but no one rushed into the thunder sea at will.

The thunder was almost non-stop, and the onslaught was endless.

Each immortal mountain has nearly 200,000 monks, stationed in turn, always maintaining the energy of the immortal mountain array and runes to fight against thunder.

Week 2, Week 3......

Under the tempering of thunder, the seven sacred mountains appeared more and more crystal clear, and the formations and runes were tempered by thunder and gradually integrated into the sacred mountains.

Among them, the Great Demon God Mountain and the Ancient Holy Mountain, which have encountered the most thunder and the greatest pressure, even have a treasure sound coming out, which is full of charm and can make the monks understand.

In fact, the Seven Great Immortal Cities were killed in the Absolute Prison, and after being tempered, the monks and mortals in the Immortal City have all gained, the monks have made great progress, and some mortals who have refined their bodies or practiced martial arts have also made great progress.

Three weeks have passed, and many brave martial artists have even begun to draw the aftermath of thunder into their bodies, tempering their physique, and making great progress.

Of course, this process is also quite dangerous and quite uncomfortable. In any case, as long as this hurdle is passed, there will be huge gains.

In its three weeks, the seven sacred mountains did not see too many gaps.

In the fourth week, after the thunder became more and more violent, Qingqiu and the Demon Spirit Demon Mountain couldn't support it at first, and the speed at which the formation runes digested the thunder slowed down, and they had to reduce the absorption of the thunder.

The demon spirit of Chel was scolding his mother in his heart at this time, those little devil cubs are definitely making a ghost out of it, otherwise, with his accumulation, he should definitely surpass Qingqiu.

Fortunately, there is a Qingqiu that is the same level as himself, if only the Demon Spirit Demon Mountain can't support it first, it will be really embarrassing and embarrassing.

Gritting his teeth, the Chel Demon Spirit swore in his heart that after this outrage, there must be a major overhaul of the style, otherwise, these demon cubs will turn the sky upside down.

The strength of the Thunder Hell Thunder was beyond Fang Yun's imagination.

In the fifth week, the power of thunder became stronger and stronger, and Storm Immortal Mountain and Sanssouci Demon Mountain could not absorb the corresponding share of thunder power, and the pressure on the Great Demon God Mountain further increased.

In the sixth week, the thunder became more and more violent, the violent thunder had begun to change color, in the void, not only silver-white thunder, but also golden dragons, appeared in the thunderclouds, stronger thunder storms were accumulating, the Ancient Ancient Sacred Mountain, and the Nengfa Immortal Mountain resisted desperately, but in the sixth week, after the last three days, the strength of the thunder also exceeded their tolerance limit.

At this time, the other six holy mountains taken together could and could only help Fang Yun share less than forty percent of the pressure.

Thunder Hell was sixty thunderbolts, heading straight for Fang Yun's Great Demon God Mountain.

Dong Jiashuai saw the apocalyptic thunderstorm, sat on Nengfa Mountain, and sent a high fighting spirit to Fang Yun: "Boss, if it doesn't work, I will incarnate into Fashan and fight with my body, which should be able to help you share one or two percent of the pressure......"

Fang Yun's hair had been electrocuted to the point that it stood on end, and his green shirt was torn into strands by the furious thunder.

The pressure of the thunder is huge, but Fang Yun doesn't want Dong Jiashuai to transform into Fashan: "It's not yet at the end of the mountain......
