In this way, time passed, and a month passed quickly.

On this day, Gu Feng suddenly opened his eyes.

"Innate spirit vein, open!"

At this moment, Gu Feng spoke, and that innate aura was directly integrated into one of his spiritual veins, and the light of that spiritual vein immediately flickered.

"Buzz!"

Eventually, the vein was completely illuminated.

A radiant innate spirit vein emerged in the center of Gu Feng's chest!

At this moment, Gu Feng's own aura is also growing violently!

"One, two more!"

Gu Feng's eyes flickered, and he also knew that condensing the first way was the easiest, and the next two were the real tests.

Then, Gu Feng's ring flashed, and a filament of spiritual energy flew out of it and landed on Gu Feng's hand.

This filament of aura is the source of the innate aura in his body given by the old monkey.

If it was to condense an innate aura out of thin air, it would be too difficult, and it could be said that it was almost impossible, but now that Gu Feng had this origin prototype, everything would not be so difficult.

Immediately, Gu Feng began to deduce the origin of the innate aura in front of him based on the comprehension he had just obtained from the innate aura that he had just refined.

"Innate aura is born by nature, and it cannot be cultivated the day after tomorrow!"

Gu Feng thought about it, cultivating innate aura, there was no predecessor to learn from, all of this could only rely on Gu Feng's own comprehension.

"However, if it is separated and multiplied by the original innate aura......"

Suddenly, Gu Feng's eyes lit up.

Then, a technique to strengthen the aura came to his mind.

This exercise is an auxiliary exercise, which was originally intended for those martial artists who have weak spiritual qi to strengthen their spiritual energy, but now it has come in handy.

Immediately, Gu Feng began to run wildly, and this time this innate aura origin filament in Gu Feng's body actually increased a little bit.

"It worked!"

Gu Feng's eyes lit up, although this aura filament did not grow too much, but as long as it grew, it meant that this method was useful.

However, this speed was still a little slow, Gu Feng's heart moved, and he directly split the innate aura origin filaments that had just grown a little, and turned them into two innate aura origin filaments.

Without hesitation, Gu Feng continued to rush this crazily!

When these two innate aura origin filaments grew a little stronger, Gu Feng split them again.

Time passed, and in a blink of an eye, another three months passed.

At this moment, in Gu Feng's eighth qi sea, there are already thousands of innate aura origin filaments densely packed with them, although each innate aura origin filament is very weak, but now that they are united, the aura is already extremely good.

"Melt!"

The light in Gu Feng's eyes flickered, and immediately, these thousands of innate aura origin filaments frantically gathered together and fused.

Airplanes......

When these thousands of innate aura origin filaments fused together, a humming sound was emitted.

An innate aura was finally conceived.

"Master, you are simply a genius, this method can be thought of, since you can't create innate aura, then multiply and breed, this is simply ......"

Lao Yu's heart was shaken, it was the first time he had seen someone who could practice innate aura in such a way.

"In this way, I can light up the second innate spirit vein!"

The light in Gu Feng's eyes flickered, with his previous experience, this innate aura was quickly integrated into one of Gu Feng's spiritual veins.

At this moment, in the center of Gu Feng's chest, the second innate spirit vein was lit up.

At this time, above Gu Feng's body, one hundred and seven spiritual veins, the light flickered, and there was only one missing, and the last innate spiritual vein could reach perfection.

At that moment, it was time to step into the sky.

Gu Feng's eyes flashed with incomparably excitement, and he took out an innate aura origin filament, this innate aura origin filament, which was the one left by Gu Feng from the countless innate aura origin filaments that had been split out when he was condensing the second innate aura.

Now, Gu Feng is going to condense the third way.

Without hesitation, Gu Feng's eyes closed and he ran again, this innate aura origin filament grew again, and then Gu Feng split it, grew again, and split it again......

This third innate aura is very difficult to condense, because it is related to the consummation of Gu Feng's spiritual veins, and all one hundred and eight spiritual veins are lit.

This innate aura must be condensed to the extreme.

At this moment, the filament of the origin of the innate aura was no longer in Gu Feng's body, but floated out of Gu Feng's body, and outside Gu Feng's body, it continued to converge.

Slowly, outside of Gu Feng's body, there were more and more filaments of the origin of innate aura......

Time is ticking.

In the blink of an eye, seven months have passed.

Gu Feng was still practicing, but he didn't know that on this day, outside the Cave of Years, a few uninvited guests came.

Outside the cave of years, no one has come for a long time, and it is a barren place.

Also on this day, outside the cave of the years, the void was suddenly shattered, and a huge dark void vortex emerged.

In the vortex of the void, a man about thirty years old, dressed in black, with an evil look on his face, walked out.

If people see this scene, they will inevitably shake their hearts and tear apart the void, which is at least a half-step martial artist of the Earth Yin Realm can achieve.

Behind this evil man, there were also four black-robed old men with thin bodies, and the breath of these four black-robed old men was also half-step yin.

At the same time, they were surrounded by demonic energy, and obviously, they were all from the demon gate.

If someone sees this scene, their hearts will inevitably be shaken, what a force can send so many half-step earth yin powerhouses at once.

The evil man, standing in the void at this moment, looked at the hole of years, and the light in his eyes flickered.

"Young Hall Master, this is it!"

A one-eyed, black-robed old man beside him said respectfully.

"Okay, it is rumored that there is creation in this hole of the years, Ben Shao has been majoring in the years of practice for many years, but now he has encountered a bottleneck and has not been able to break through, this is Ben Shao's opportunity!"

The light flashed in the eyes of the evil man, and he looked at the four old men and said: "The four of you, immediately arrange the formation to isolate the breath here, we can't enter the world at will, this time it is already a violation of the rules, and it must not be noticed!"

"Yes, Young Hall Master!"

The four one-eyed old men immediately spoke.

Immediately, the four of them immediately dispersed to various places around the Time Cave, and they all pressed one palm on the ground, and soon a demonic formation light curtain appeared.

This time, the breath of this place is completely isolated......
