It was only on the last day of every ten years of the Four Great Sect's trial, when the restrictions on it would temporarily disappear. This day, was the day the four great heaven's pride level disciples of the Sect reaped their harvest, and was also the day when the countless demons and monsters in the Thousand Demon Mountain Range reaped their harvest. Although the majority of the spirit grass and strange fruits were only effective against Warrior s of the human race, there were still many spirit roots that were suitable for the The Demonic Clan!

Furthermore, with such thoughts in mind, even if they could not use it themselves, they would not allow others to obtain it. Before the opening of previous Wanling Mountain s, countless demons and individuals, under the command of all the great Demon General s, would seal off the places in the Wanling Mountain in all four directions, in case the heaven's pride experts of the human race decided to climb the mountain.

In order to compete for spiritual medicine, one had to first bring out enough strength to break through the countless demons' seals. If one couldn't even climb the Wanling Mountain, then this kind of good-for-nothing disciple simply didn't have the qualifications to go up the mountain to gather spiritual medicine!

Compared to previous sessions, this session of experiential learning had more than ten times more difficult to climb the mountain. In the previous sessions, the most powerful s were only a few lower ranked Demon General s, and the number of people in the top thirty of Earth Proclamation or even in the top ten of Human Ranking s, were generally less than a hundred. As long as one's luck wasn't too bad, one would be able to enter the Wanling Mountain, but in a circumference of a hundred kilometers, there were more than ten thousand lower ranked Demon General s.

The sky gradually darkened, and even the divine light on the Wanling Mountain seemed to have disappeared. At this moment, with the Wanling Mountain at the center, everything within a hundred miles seemed to have sunk into absolute darkness, as if the black hole had devoured everything in the world, as if it wanted to devour everything in the world!

All of a sudden, the dark space was torn open like a curtain. In the blink of an eye, a youth dressed in black appeared, who seemed to have merged with the environment in all four directions!

It was a young man of about fifteen to sixteen years of age. He looked refined, and his breath was very flat, just like a rich young master who didn't know any martial arts, but by chance, the faint aura he gave off gave off gave off the feeling of a god descending upon the earth. His pair of deep eyes were like the starry sky of the universe, filled with countless stars, making one unable to resist his intoxication and his hands were clasped behind his back.

It's Yang Fan!

Not long after, he bade farewell to Situ Jing and the others. Although Situ Jing and the others were extremely unwilling, as she was the master of a peak alone, killing Peerless Great Demon as strong as the Green Flood Dragon Great General himself, if he had him, even if the Thousand Goblins Mountain runs wild with them and the Demon General is numerous in all directions, they would still be able to do whatever they want with him. Unfortunately, Yang Fan's decision was not something they could control!

Entering the Thousand Goblin Mountain Range, Yang Fan had always had a sense of urgency in his heart, as if a voice was telling him that one day he would meet that peerless great demon. Right now, although his combat strength is unparalleled and his Xuan Iron Battleform is at full power, he still doesn't have much of a chance to win against that peerless great demon that has transformed into a flood dragon. To be able to forcefully change the rules of the secret realm meant that he is at least a half-step Demon Marquis, and is very likely to be a genuine Demon Marquis.

Rather than placing all his hopes on unreal luck, increasing his own strength would be a walk in the park. At that time, even if he still couldn't beat that old demon, it would still increase his chances of survival.

The secret of the Great Art Of Devouring The Heavens And Devouring The Earth was something even his parents Yang Fan did not dare reveal, not to mention these fellow sect members, even if they could not completely see through its mysteries, Yang Fan would not dare to be careless!

Just a Earth-grade technique was enough to cause thirteen nations' billions of Warrior to go crazy for; a Celestial Level, or even a higher rank legendary technique, if it was exposed, how terrifying would it be?! With such a large South Mountain Domain, or perhaps even the entire Sobbing Blood Continent, there might not even be a place for Yang Fan to stand on!

At that time, not only would he die, but his parents and his entire family would be buried with him!

After parting with Situ Jing's group, Yang Fan found a hidden place and began his closed door cultivation. This closed door cultivation lasted for nearly half a month, and it was only two days ago that he officially emerged from closed door cultivation!

It was said that True Dragons liked to collect all kinds of treasures, and it was not a lie. Although the Green Flood Dragon Great General was not a True Dragon, and could not even be considered a Flood Dragon, as a direct descendant of the Dragon Clan, he had also inherited the habit of collecting treasures from the Dragon Clan.

Even though there were many treasures that were suitable for the use of The Demonic Clan, for human Warrior s, not only did they not hold any benefits, they were even poisonous medicines. Even so, with the filth of the human Warrior's treasure body, it was still extremely terrifying, comparable to the vast majority of Ancestor Martial Marquis s, it was still above and beyond, not to mention that in these thousands of years, Green Flood Dragon Great General s had hunted down and killed countless number of Four Great Clans, there were no more than two thousand, there were at least a thousand or several hundred people, and most of those heaven's treasures had already fallen into the hands of Green Flood Dragon Great General s.

The thing that made Yang Fan most excited was that there was actually a Black Iron Heart in Green Flood Dragon Great General's treasury. Although its weight wasn't as heavy as the one Lu Bingling traded it to him, it was still almost fifty kilograms. Not only that, there was also a considerable amount of Black Iron essence.

Although it could not compare to Black Iron Heart, it was still far from what ordinary Black Iron could compare to. Normally, ten kilograms of Black Iron would only be able to refine a single gram of Black Iron essence, and the utility of one kilogram of Black Iron essence was almost as good as ten tons of Black Iron essence. Moreover, the Green Flood Dragon Great General's treasury had nearly ten tons of Black Iron essence, which was simply unimaginable.

It had to be known that for normal Inferior Demon General, refining a Black Iron with their own life demon fire, and refining one or two pieces of Black Iron essence a day, was the limit!

However, all of these things were for Yang Fan's benefit!

In this half a month, Yang Fan had spent most of his time refining the Black Iron's essence, but even so, he had only barely refined a ton of the Black Iron's essence. The Black Iron's essence was not comparable to the Black Iron Heart's, but the difficulty of refining it was still more than a hundred times harder than that of ordinary Black Iron's. Even though Yang Fan's Black Iron Battle Body had already reached a small success, and the speed at which he refined it had increased exponentially, he was only able to refine around one hundred or so kilograms of Black Iron's essence in a single day.

Very quickly, several hours had passed, and the night sky turned white once again. But what was strange was that the endless multicolored light on the peak of the Wanling Mountain seemed to be suppressed by something, and it was almost transparent. If one did not look carefully, they would not even be able to see a single speck of multicolored light.

In the end, it completely disappeared without a trace, as if it never even existed. In an instant, the Wanling Mountain that looked like a divine mountain fell from the sky like a god and became a member of an ordinary mountain!

At this moment …

"Roar!", "Roar!", "Roar!" …

The devastating roar shot up into the sky, shaking the entire world. Numerous terrifying waves of sound spread out for tens of miles in every direction. Large areas of the void were destroyed into pieces!

In the next moment …

One after another, terrifying demonic shadows soared into the sky from the surging demonic energy, like tidewaters, straight into the Wanling Mountain that was gradually returning to normal.
