The huge scope of this Erdu Mountain, Xue Zhen spent nearly two months traveling, circled around twice, and did not find any monks, and those spirit beasts and birds were also almost extinct, the whole mountain range can be regarded as barren, with very little green clothing, fortunately, the fairy aura here is not shallow, which also makes Xue Zhen full of confidence that he can solve the bottleneck here.

Soon, Xue Zhen chose a mountain peak that was about half a day away from the highest peak of Erdu Mountain, with a height of 13,000 or 4,000 zhang, and the wind was blowing strongly.

Unleashed a number of array flags, the Spirit Gathering Array was built, and he dodged away, Xue Zhen sat cross-legged on top of a flat rock in the Spirit Gathering Array, and silently cast a trick to refine mana.

In about half a month, Xue Zhen had fully recovered all his mana, and tried to hit the bottleneck of the middle stage of the primary stage, just like last time, Xue Zhen was able to break through some of the bottlenecks, but this process only lasted for two years, and he once again encountered stagnation.

At this time, Xue Zhen slowly opened his eyes, a firm gaze came out of his eyes, at this moment, he looked at the sky intentionally or unintentionally, above the sky, the distance is not too far, Xue Zhen can sense the kind of sharp whirling wind, those clouds that are difficult to see with the naked eye, from time to time crackling, and flickering faintly, this kind of light is very shallow, Xue Zhen also looks faintly clear.

Soon, Xue Zhen came back, thinking for a little while, a formation trick had appeared in his sea of thoughts, and he was already in the flickering of spiritual light in his hand, a stack of array flags, a stack of steel array flags had appeared in his hand, these were the steel array flags after the liberation of the Nine Micro Dust Array.

And Xue Zhen's eyes flickered, without hesitation, between the light waves of his sleeve robe, this stack of array flags was thrown, and as Xue Zhen's mouth urged out the formation technique, each of these rigid array flags showed off a trace of forbidden light at the same time, and the forbidden light was full of color, scattered in all directions, and "swishing" straight to the ground.

Subsequently, Xue Zhen Shennian sent out a careful inspection, confirming that these array flags fell according to his own formation technique, and after that, some other ordinary array flags also swam out under his urging and inserted them into the ground one after another, and the corresponding positions were somewhat similar to the steel array flag points, connected to each other, but as if there was no connection.

As Xue Zhen's mantra was recited one by one, a touch of glow appeared in an instant in this not small place, sticking to the ground, but Xue Zhen sat cross-legged in the appearance of the glow, these ground light curtains with the corresponding forbidden light flowed in an instant, and lifted outward, a half-circle of forbidden light curtain flashed at the same time, another edge of the light cone was erected in the forbidden array, this light cone has six edges, in addition to the color of the streamer, there are some colored light runes on the surface, which looks very mysterious.

"The Seven Xuanhua Thunder Array, combined with the dry day clear thunder triggered by the Oblivion Blood God Thunder, I hope to be able to remove the bottleneck!" Xue Zhen said in a faint voice.

This edged light array is the Seven Xuanhua Thunder Array that Xue Zhen had established earlier to induce and reduce the Heavenly Thunder, but at this time, it was arranged through the Guò Rigid Formation Flag, and the kind of stability and hardness were not comparable to the Seven Xuanhua Thunder Arrays in the past. As for the other half-circle light curtain, it was the Thunder Crossing Heavenly Curse Absolute Array that Xue Zhen used to guide the Heavenly Thunder, and the form of this array was similar to that of an ordinary forbidden array, but the power in it was completely different from an ordinary forbidden array.

After preparing all the qiē, Xue Zhen looked up at the sky again, and before he knew it, the two arms in his hands were changing, and one after another strange rune spells flashed in his hands, and gradually floated up, sending out, encountering a half-circle forbidden magic array, crossing the thunder heaven curse array, and all of them were absorbed into it. As Xue Zhen's casting continued, the rune spells absorbed by the Thunder Heaven Spell Absolute Array increased more and more, and the original faint light forbidden on its surface gradually turned into a deep color.

Time continued to pass, Xue Zhen's face was slightly solemn, and the increase in rune spells seemed to have reached a rare level, and the curtain of the Thunder Heaven Spell Formation turned into a completely dark color, and the slightest flow could still be seen on it. The outside world seemed to have entered the night in Xue Zhen's eyes, into the night of ignorance, and the movements in Xue Zhen's hands were also put away under a slap.

However, Xue Zhen didn't mean to let himself rest, and suddenly, the posture in Xue Zhen's hand changed slightly, and the magic trick was urged, carrying a pure mana, Xue Zhen slowly moved towards the black circle curtain above, as if he was slow and urgent, but the magic with pure mana had already touched the dark circle.

"Boom ......"

A huge and incomparably shocking sound came out, and on the surface of the Thunder Heaven Curse Array, a little crystal light flashed, and then the crystal light turned into a large one, forming a surface, forming a circle, and the increasingly large circle curtain suddenly became a crystal light curtain, and Xue Zhen, who was in the middle of it, still injected pure mana endlessly, and he also clearly felt a kind of falling pressure, the pressure of texture, and his face became slightly distorted.

However, what followed was a loud bang, a huge explosion that spread thousands of miles away, above such a crystal light circle, a beam of rainbow light reaching nearly three zhang square, the rainbow light of difficult color went straight to the sky, and it was the clouds that accumulated on the tens of thousands of zhang.

Such a beam of rainbow light, when it shot out, it actually carried that kind of heavy sound that could shock the heart, and it hit away without hindrance, Xue Zhen's divine thoughts followed it, and the rainbow light shot up, just half of the blink of an eye, it had already touched a cloud layer, and the clouds could not see anything unusual, but Xue Zhen had quickly collected his thoughts and returned, and sat cross-legged, his solemn expression was like the posture of a great enemy, and there was a certain magic trick in his hand.

After the rainbow light was excited, the original light color of this half circle, then dark black, and then the crystal curtain of the circle was restored to its original light color again, and even under Xue Zhen's automatic excitation, it turned into bursts of broken light and disappeared into nothingness after a while.

As for the clouds above, under the stimulation of the Thunder Heaven Curse, after a short period of time, the faint blue clouds turned gray, ink, and black, and these black clouds were about a few miles in a radius of about a few miles, and within the clouds, a little golden light continued to flash, like a few golden fireflies fluttering in the night sky, which looked quite weird and eye-catching.
