After three Chaos Gang Wind Explosions, Qin Yuan knew very well how powerful the Gang Storm's destructive nature was. Therefore, before Qin Yuan really sharpened the prototype of the Eighteen Hells, he needed to transform the passage and introduce the erupted Chaos Gang Wind into a specific position in the cave to accumulate it, so that it would be much easier to control than directly placing it outside the cave, and Qin Yuan was sure that if he really placed the rune source point of the Eighteen Hells Divine Power outside the cave to sharpen it, twenty years of hard work would be in vain.

The transformation of the cave was very simple, and Qin Yuan only took three days to complete it.

Not long after Qin Yuan's transformation, the fourth Chaos Gang Storm broke out after Qin Yuan's transformation.

Although he had seen it twice and experienced it three times, Qin Yuan was once again uncontrollably immersed in such a grandiose and crazy scene that soared straight into the sky.

It wasn't until Gang Storm approached the entrance of the cave where Qin Yuan was again that Qin Yuan turned back into the cave and got ready.

Soon after returning to the big array, the Chaos Gang Wind came as scheduled, and the violent Chaos Yin Soul Gang Wind poured into the cave entrance, every time it passed a bend and the wear and tear of the solid stone on the cave wall, the destructive characteristics of the Chaos Gang Wind would be weakened a little, so bending and twisting, turning and turning, and finally an endless stream of Gang Wind poured into a circular giant hole specially dug by Qin Yuan, the most special thing is that the entrance of this giant cave was set up by Qin Yuan to only enter and not exit, so I saw the Gang Wind poured in but did not leak out.

At the beginning, after Gangfeng entered the cave, it had no effect on the giant cave because of the sparse density, but with the infusion of Gangfeng in large quantities, the density of the Chaos Yin Soul Gangfeng increased rapidly, and the cave began to do vortex movement because of the blockage of the passage, and the Chaos Yin Soul Gang Qi gradually condensed into Gangshui.

The walls of the cave were also enlarged three or four times by the heavy water because they could not withstand the increasing pressure in the cave.

Qin Yuan, who was hiding in the Emperor's Heavenly Queen's Earth Great Array, silently calculated the density of the chaotic wind in the cave in his heart, and just after the giant cave was expanded five times, Qin Yuan opened his eyes impressively, "It's this time." ”

Qin Yuan raised his hand, and the source point of the eighteen hell runes that had been cultivated and refined for twenty years in the sea of knowledge was drawn out, and with a flick of his fingers, the silver black suddenly turned into a streamer and melted into the center of the water vortex that had already turned into Gangshui.

As soon as you enter the chaotic yin soul qi, the rune source point seems to be set up on the grinding plate, and the huge water mill pressure is trying to compress and ponder the rune source point, while also dissipating the impurities and incongruities existing in it, and these places will also frantically absorb the chaos yin soul qi from the outside world to supplement the consumption after being exhausted.

Under such repeated grinding and supplementation, first the outermost layer of the first layer of Hell Rune Shell was worn and crushed, and finally all the mud pear rune shells condensed into a perfect black round shell under the huge pressure of the outside world, and there was no trace of it being composed of mud pear runes at all.

Then came the second layer, the third layer,...... With each layer, the external pressure required must increase exponentially in order to complete the pondering of the inner layer, because the shell is getting thicker and thicker, and it is becoming more and more difficult for the Chaos Yin Soul Qi to penetrate into the inner layer.

By the time he reached the seventeenth layer of the inner layer, the pressure in the giant cave even made Qin Yuan a little pale, and he couldn't be sure if the Gangshui Vortex in this cave exploded, whether the Emperor Queen Earth Array he was in would be able to resist the power of the Gang Qi released at the moment of the explosion.

It was just that when he was dissipating the rune shell that had integrated the seventeenth layer, Qin Yuan's complexion couldn't help but change slightly, because the magic spirit reminded him that the Gangshui Vortex had not increased its pressure for a period of time, that is to say, if there was no change, the pressure of the Gangshui Vortex would be fixed.

Twenty-five days had passed in the thirty days, and in another five days, the Chaos Gang Storm outside the cave would have to recede, so if he wanted to continue cultivating the Eighteen Hells, he would have to wait for another ten years. This was not the result that Qin Yuan wanted to see.

Qin Yuan gritted his teeth, he had the simulation calculation of the Fa Spirit beforehand, and this situation was naturally within his sudden plan.

"Xiaoqing, according to Plan Three, act. ”

"Okay, Xiaoqing can help Baba. Xiao Qing, who was obediently staying in Qin Yuan's hair and waiting at any time, jumped and flew into the chaotic flow that was raging in the passage.

Time passed slowly, and after a stick of incense, there was a loud bang, and another chaotic gang wind rushed straight into the gang water whirlpool from the other direction, which was another straight passage that Qin Yuan had dug long ago, and there was no straight passage that turned around and turned, retaining most of the power of the chaotic gang storm outside the cave.

With the help of this, the Gangshui Vortex, which had a somewhat stagnant power, actually made a clicking sound in a short period of time, if Qin Yuan's Eighteen Hell Rune Source Points were placed in it without any grinding, it would definitely not be able to resist this sudden increase in the pressure of the Gangshui Vortex. However, with the completion of the integration of the seventeenth layer rune group, the eighteen hell rune source points were able to withstand this sudden increase in pressure, and even after further sharpening the first seventeen layers, this pressure finally penetrated into the final eighteenth layer.

As time passes, if the previous Gangshui Vortex was just a steel boiler, then the Gangshui Vortex at this time has truly become an active volcano that may erupt at any time. But even so, the progress of sharpening the final eighteenth layer of runes can only be described as turtle speed.

At this point, Qin Yuan finally realized the difficulty of cultivating supreme supernatural powers.

Don't look at Qin Yuan's previous two steps, it seems that they were easily completed, but this is just his chance to meet, if he changes places, Qin Yuan can be sure that just finding a high-quality negative Gang Qi can spend half of his life. It's just that there is too much negative qi that needs to be consumed, especially in the third step of the grinding stage.

Time flew by, and just one day before the Chaos Gang Storm receded, the source point of the Eighteen Hell Runes finally left only the part that contained the true meaning of the space at the core.

Bang, bang, bang, at the moment when the innermost runes were integrated, the eighteen layers of rune shells that had been formed inside and outside lit up together, and suddenly condensed into one point, and there was no difference between inside and outside. The shimmering silver-black light shone in all directions from this point, and all the Gangshui shrouded in silver-black light was like a hundred birds returning to their nests, and was swallowed by the whale that did not refuse to come, and after swallowing more than half of the Chaos Yin Soul Gangshui in the giant cave, it was as if it was full, and it hiccuped.

Qin Yuan didn't have time to rejoice that the source of the eighteen hell runes had invisibly eliminated the crisis of the volcanic eruption, and he still had the most important thing to do.

Taking advantage of the emptiness in the cave, Qin Yuan appeared next to the source point of the eighteen hell runes like lightning, stretched out his hand and grabbed it, and the source point obediently fell into his palm. Then, without waiting to take a closer look, Qin Yuan's figure quickly walked towards the entrance of the cave.

Xiaoqing happily shuttled in front of Qin Yuan, helping Qin Yuan sweep and suppress the Gangfeng that rushed into the passage frantically, and seriously weakening the Gangfeng wheal that rushed to Baba for Qin Yuan.

The entrance of the cave was looking at it in a blink of an eye, "Xiaoqing protects the Dharma for me." Qin Yuan stopped at the entrance of the cave and said.

"Well, Xiaoqing will protect Baba. Xiaoqing's eyes were firm and serious. At this time, Xiaoqing had already turned into an eighteen-winged green snake, the snake body surrounded Qin Yuan in the center, and nine pairs of sky-covering wings surrounded the periphery.

"Go ahead. Qin Yuan grabbed the rune source point and let it go, and the rune source point suddenly rushed into the chaotic wind like a wild horse. At this time, the rune source point was not as weak as before, and even this violent Chaos Gang storm did not cause any obstacles to him.

"Eighteen hells, ten halls of Yama, six realms of reincarnation, hell...... Befall. Qin Yuan played a series of magic tricks in his hands, and with each spell, the huge true power, true yuan, and divine thoughts in his body would be extracted and condensed into a spiritual light by the magic tricks, and flew into the rune source point that was free in the storm as if it had a spirit.

It wasn't until Qin Yuan shot out one hundred and eight spiritual lights......
