This is shocking news.

Gu Tianfeng suppressed the ecstasy in his heart, he had already cultivated the 'Realm of Oneness' to perfection, and in terms of artistic conception alone, few people in the entire reserve camp could surpass him.

This training ground must be visited, and the sooner the better.

Gu Tianfeng made up his mind, thought about it again, and smiled bitterly, the Gathering Spirit Pill was not enough!

It takes a thousand Gathering Spirit Pills to observe for an hour, and at present, the Gathering Spirit Pills on his body plus the Gathering Spirit Pills that have cleared the ancient hall add up to more than 7,000.

Seven hours of observation!

Gu Tianfeng was not confident enough to completely master the 'first-line sky' after seven hours of observation, which was very unrealistic.

After all, there are many martial artists in the preparatory camp who are proficient in artistic conception, but it is still difficult to break through and leave here after so many years of enlightenment, and it is indeed not easy to come to this 'ghost drawing talisman'.

"Anyway, let's go and confirm what this cultivation ground is like first. Gu Tianfeng decided to go and see it in person, so that he also had a bottom in his heart.

Leaving Wanbao Tower, the five of them separated, and Gu Tianfeng came directly to the cultivation ground.

The captain's reserve camp is very large, and each building occupies an extremely large area, especially some special places, such as the trading house, the secret treasure room・・・・・・ especially this cultivation ground, which sits in the middle of the mountains and is located in the ravine.

It was a canyon with mountains on either side, cut short by a dark iron gate.

"This fine iron gate..." Gu Tianfeng raised his head and sighed, "At least ten meters high. ”

Refined iron is a very precious material, very hard, but because of its bulkiness, it is only suitable for armor, but the reserve camp is rich and rich, and there are fine iron gates almost everywhere, and this one is larger.

"Who is here?" In front of the gate, two old men, one black and one red, stood there like two door gods.

Gu Tianfeng knew that these two must be one of the old bones, and said respectfully, "I want to enter the cultivation ground to observe." After speaking, he took out three thousand spirit pills and handed them over.

"Hmm. One of the black-robed old men took it and said, "Three thousand, you can observe it for three hours." ”

After speaking, another red-robed old man took out a milky white bead, handed it over with a bull's eye, and said, "This is an air-holding bead, which can protect you from being invaded by miasma, and you will return it to me when you come out in three hours." ”

Gu Tianfeng took the breath-holding bead suspiciously, put it in his arms, and thought to himself: Miasma?

Without waiting for him to think about it, the dark and huge fine iron gate was pushed open, and Gu Tianfeng walked in, and suddenly, as if entering a battlefield, there were rusty and broken weapons everywhere, and the air was full of turquoise green mist, which transformed into various forms, like a grimace for a while, like a skull for a while, and then into the shape of a hanged ghost, which was extremely terrifying.

"Huh?" Gu Tianfeng frowned, feeling that his breathing was miserable, and his chest seemed to be blocked by something.

"Buzz !!"

With a slight tremble, the breath-holding beads in his arms were glowing, and the light diffused, enveloping him, and at this moment, the feeling of tightness in his chest suddenly disappeared.

"This is the cultivation ground? No matter how you look at it, it looks like an ancient battlefield. Gu Tianfeng shook his head, the soil on the ground was damp and dark brown, and there were bare hills all around, but through the turquoise green smoke, it was more like a ghost mountain standing in mid-air.

"Huh, the stele?" Not long after, a huge stele rose from the ground in front of him, and Gu Tianfeng walked a few steps quickly.

The stele is huge, three meters high, but it is old, weathered so badly, it has been tattered, and there are three people sitting next to it, all of whom are warriors of the reserve camp, watching the stele attentively.

"It's so profound, I can't understand it. One of the female warriors whispered.

"Me too, they all say that this scratch contains the 'first line of heaven' of the three realms of power and precision control, but I just can't see it. The same goes for the other person.

"Me too, it looks like an ordinary scratch no matter how you look at it. The crowd smiled wryly.

Gu Tianfeng was overjoyed, it actually contained a 'glimmer of heaven', he trotted to this side, the speed was too fast, kicked over a lot of gravel, and disturbed those people.

"Who?" The three of them stiffened, and suddenly heard a few strange noises in this silent cultivation ground, and everyone was afraid.

"Hello brothers and sisters, I'm here to watch this stone monument. "Gu Tianfeng gave up.

A few people seemed to breathe a sigh of relief, their faces softened a lot, and said, "Then sit down, so do we." ”

This is a stone tablet that records the 'first line of heaven', and the people who want to watch it are all taking the route of precise control of the force, and everyone is not able to understand it, so they simply gather together to discuss the next countermeasures.

Gu Tianfeng's mind was on the stele, and he looked at the stele with all his attention after dealing with a few casual words.

A scratch!

To be precise, it is a very thin scratch, only as thin as a hair, from top to bottom, straight and slender, a meter long, and it is impossible to distinguish the end and the beginning, because the depth of the two ends is the same, and the place around the scratch is very complete and ordinary.

But Gu Tianfeng's eyes widened, and he felt that something inside seemed to be about to break out.

Suddenly-

"Flutter !!"

A strange voice sounded in Gu Tianfeng's ears.

"Huh?" he was startled, and a cold sweat broke out, the voice was all too familiar to him, the sound of a sharp weapon cutting a stone as sharp as cutting tofu.

He looked at the few people next to him, who were still talking, nothing out of the ordinary.

"Illusion?" Gu Tianfeng shook his head and looked at the stone stele, once again engrossed in observing the scratch.

"Flutter!"

The voice sounded again, and this time even a faint picture was seen.

Gu Tianfeng was shocked and couldn't believe it: "Could it be the sound of this scratch?"

He was not sure, and looked at the stele carefully, this is, the voice sounded again, and at the same time, the picture was more clearly visible.

"What a strong move. Gu Tianfeng's eyes widened, and he saw a strange picture from it.

A white light crossed the stone wall, and the dark stone wall was still smooth, but, after a while, very suddenly, a crack with a thin hair suddenly appeared, instantly pulled out a meter away, and finally disappeared suddenly, straight and slender, without a trace of bending, the action was smooth, and the scratches were bottomless, exactly the same as the scratches on the stone tablet.

"This~~~~" Gu Tianfeng was shocked and said secretly: "Could this be the secret of the stone tablet?"

That picture and that sound is the secret of the stele.

That's right, it's just a stone stele, no matter how magical the scratches on it are, they are always scratches, and the most important thing is the special realm contained in the scratches.

Gu Tianfeng's artistic conception is perfect, and his precise control realm of strength is high enough, so he can see the difference at a glance.

His body trembled, his eyes were like two divine suns, and he muttered to himself: "I saw it, I saw it, that is the 'silver line of heaven'." ”

Gu Tianfeng tried hard to suppress the joy in his heart, he successfully observed the stone tablet, and that picture was deeply imprinted into his mind.

"Although the scratch was very long, the force contained in it was very uniform, and there was no diffusion at all, all of it was concentrated and extended. Gu Tianfeng pondered.

'A line of sky', as the name suggests, a line of sky.

The force is completely overlapped and turned into a line, how long the day is, how long the line can be, and there is no need to stick to how to condense the line to increase the cutting force.

In other words, the longer the 'line' is used, the more powerful it is.

"This..." Gu Tianfeng was shocked, because this was the opposite of the path he had taken to cultivate the 'First Line of Heaven'.

Generally, no matter how strong the power is, after a certain distance, the force will gradually disappear, so when casting the 'first line of sky', shorten the 'line' as much as possible, concentrate the force, and the power will naturally multiply.

And the artistic conception on this stone tablet tells himself that as long as he maintains enough strength, he can go down with a knife, even if the sky can be dissolved, the distance is infinite.

"It's crazy. "Gu Tianfeng is a little confused, the 'line' is infinitely far away, so isn't the force dispersed?

Gu Tianfeng pondered hard, he didn't doubt the stone stele, he was just thinking about whether he had missed something.

"A silver lining!"

"Line!"

“・・・・”

"What is a 'line'?" Gu Tianfeng opened his eyes suddenly, grasping the flash of inspiration in his heart.

"The 'line' itself represents the length of the line, and its real meaning lies in the thickness. ”

He stood up violently, and finally couldn't suppress the excitement in his heart, and kept walking back and forth because of the excitement.

"There is no thickness of the line, the real 'line' does not care about the thickness, but whether you can overlap the force on the line infinitely, if it is stretched by one point, the force will be superimposed by one point, and finally it will be turned into a real 'line', which is integrated, even if it is stretched no matter how long, the force on the line will always remain the same. "At this moment, Gu Tianfeng walked out of the misunderstanding and understood the true meaning of 'a line of heaven'.
