Then, with a leap, it turned into a golden light and immediately pounced on the other Ghostly Flame in the passage. Every time it met a floating Ghostly Flame, it opened the snake's mouth and swallowed it as if it had encountered the most delicious food in the world, making a satisfying sound.

"Ah, what, what the hell is this?" Feng Laodao seemed to have seen ghosts. No, he had seen ghosts many times, but he had never seen anything so frightening.

On the other hand, Xiao Yi rejoiced when he saw this. He had known Gu Lu was extraordinary. The more poisonous it was, the better its food would be. Now, it was actually able to devour the Ghostly Flame. Xiao Yi was happy in his heart. How could he give Feng Laodao and the others a chance?

The Nine-sun Net and the Fire Dragon Cauldron came out at the same time. They rushed to Feng Laodao and the others.

At the moment, Feng Laodao was already in a panic. Seeing that Xiao Yi's Nine-sun rushed to him, he didn't care about Gu Lu eating the Ghostly Flame. He waved the Demon Banner in a hurry and tried to resist.

However, the situation was now hopeless. Xiao Yi's Nine-sun Net immediately enveloped several Demons, turning them into black smoke and taming their vengeful souls in an instant.

The Power of Merit increased sharply, and Xiao Yi became braver, while Feng Laodao was utterly defeated. The evil cultivators of the Yinfeng Sect all escaped out of the passageway as soon as they realized the situation was over. They couldn't wait to retreat.

Feng Laodao's green eyes turned red at the moment, and he wished to grab Xiao Yi and eat him alive. But he also knew that he couldn't get any benefits at all. He had suffered a great loss, so he could only endure his hatred and wait to avenge himself in the future.

He wrapped the Demon Banner around his body and a black cloud was set up. He immediately fled out of the passageway as fast as lightning.

"Brat, just you wait! I will get my revenge." Feng Laodao cried out with a ferocious expression.

However, in the next second, he was plunged into a layer of invisible restriction formation.

The restriction formation did not exist when he entered. At this moment, it appeared out of nowhere. It was resplendent and had the Five Elements Energy. Just as he was about to hit it, he was attacked by the Five Elements Energy. Even though it did not kill Feng Laodao immediately, it caused him to be in a terrible state. The most terrible thing was that it blocked his footsteps as he fled.

"F*ck, why are there restrictions in this passageway?" Feng Laodao could only feel an ominous premonition that enveloped his heart.

At this moment, Shangguan Leiting's furious voice came from behind Xiao Yi. "You traitor. How can I not take revenge for the broken arm? Do you think that Smarty Mountain is a place where you can come and go as you please? There are more than 80 kinds of restrictions in this passageway. When you came in, only half of them were destroyed. It's almost impossible for you to escape from here!"

Upon hearing this, Feng Laodao's face turned pale with fright.

The evil cultivators, who were fleeing with him, were even more terrified. They took out their magic weapons and rushed together to the Five Elements restriction. However, it did not work at all.

When they were in a state of despair, the wind behind thier heads suddenly rose, carrying a sharp killing intent. It was Xiao Yi's Nine-sun Net and Fire Dragon Cauldron that had come to kill them again.

With the restriction in front and lethal weapons behind, they could do nothing even if Feng Laodao and the others resisted with all their strength. All of them were smashed into pieces and died.

Several souls struggled to escape from the dead bodies and fled to Samsara in a hurry.

As of now, a total of 16 evil cultivators from the Yinfeng Sect had made their way into the Smarty Mountain, and their entire group had been wiped out.

Shangguan Leiting and his daughter fell to the ground after this sudden change. They were all exhausted and soaked in a cold sweat. After that, they were scared to the extreme.

During these short two days, they experienced a couple of life-and-death situations. If it were not for Xiao Yi, they would have died several times. Now, after surviving a calamity, it was as though their lives had been separated forever.

Xiao Yi strode in front of Shangguan Leiting and sealed his bleeding left shoulder. He then took out a medicine to stop the bleeding and bound Shangguan Leiting. However, he said with regret, "Mr. Shangguan, I can't do anything about your left arm."

Shangguan Leiting's forehead broke out in cold sweat. He waved his hand and said weakly, "Mr. Xiao, it's a great fortune that we've managed to escape with our lives. How would we dare to hold a grudge against an arm?"

Xiao Yi nodded his head and did not say anything else. Instead, he looked at Gu Lu which had just consumed the Ghostly Flame.

Its golden body seemed to have been expanded. It burped all the way and could not fly. In the end, it only could turn over the somersault and walk toward Xiao Yi's Fire Dragon Cauldron.

Xiao Yi had witnessed Gu Lu's several strange changes. He was surprised, but he did not interfere. As Gu Lu climbed over the cauldron, it fell into the Kun Formation that held the Sky-ghost. Then, it fell into the arms of the Sky-ghost and fell asleep.

The Sky-ghost also did not move, and it was badly hurt by the Nine-sun Net. At this moment, it had been in a coma and let Gu Lu slip into its arms.

Xiao Yi knew that devouring so much Ghostly Flame, ranked seventh in the Cultivation World, was an excellent opportunity for Gu Lu. As for what this opportunity meant for him, he didn't know.

Xiao Yi relaxedly kept the Fire Dragon Cauldron after sensing that its breath was gentle and there was nothing wrong with it.

At the same time, he waved his hand at the already smashed corpse. The black Demon Banner and the dirty oil lamp fell into Xiao Yi's hand.

The pitch-black Demon Banner was actually similar to the Soul-summoning Flag in Xiao Yi's hand. However, its level was a little higher. Whether it was the material needed to refine the Demon Banner or the number of Demons in the banner, it was not something an ordinary Soul-summoning Flag could measure up to.

Xiao Yi held it in his hand and took a closer look. He found that the long banner of the Demon Banner was made of thousands of human skins, which made Xiao Yi extremely disgusted.

It was particular about making living people suffer all kinds of cruel torture. The skin would be peeled off when the morbid air was most intense. At this time, the skin would increase the Demon Banner's morbid Qi and be the most elastic. After special refining, the skin could create a space to tame the Demon God and isolate Yin and Yang. Thus, it was highly vicious.

Xiao Yi had always abhorred something that went against the Natural Law. He immediately took out 81 five-colored banners from the Micro World and placed them on the ground. Then, he created a simple formation that could link to the cycle of reincarnation. Then he placed the vicious Demon Banner into the formation. He triggered his True Energy, and the Demons roared and came out of the banner one after another. However, as soon as they came out, they were all sucked into the Nine-sun Net by Xiao Yi.

The Demons cried out in pain. Eventually, they were refined into wisps of black smoke. The Demon Banner contained tens of thousands of vengeful spirits. Once they had the chance to reincarnate again, the entire passage was filled with souls. They all kowtowed to Xiao Yi and then rushed into the Gate of Samsara.

The Power of Merit brought about by the tens of thousands of souls exceeded Xiao Yi's limit, making up for the loss of Xiao Yi's Divine Awareness and causing his Mind Sea to tremble and rise to Level 8.

There was a flash of starlight in the Mind Sea, and the whole world suddenly quieted down in Xiao Yi's mind. However, everything around him was infinitely clear. Even the sound of an ant crawling over the ground in the passage could be clearly passed to Xiao Yi's ears.

In the vastness of the world, an unprecedentedly clear feeling filled Xiao Yi's entire Divine Awareness. This feeling was indescribably wonderful.

Then, specks of starlight turned into a wave of Yu Feiyan liquid. It followed the Mind Sea, entering the Elixir Field, linking up with the Gold Elixir within the Elixir Field, and nourishing it.

As a result, the tiny central vein connecting the Elixir Field and the Mind Sea had become a little wider.

One day, when the Gold Elixir dissipated, and the Nascent Soul Realm Realm was completed, this central vein would be the key. Now that he had seen the extension of the central vein, Xiao Yi was naturally overjoyed.

After all the spirits had entered the Gate of reincarnation, Xiao Yi withdrew the formation. With a push of his True Energy, the Demon Banner, made of countless pieces of human skin, was also completely destroyed, lest this thing brought disaster to the world again.

The thick iron pole supporting the Demon Banner was pure Dark Metal. The best materials for forging weapons were left by Xiao Yi and thrown into the Mirco World.

Only after dealing with all of this did he have the opportunity to size up the dirty oil lamp. From its outer appearance, it seemed that there was nothing special about this lamp. However, after taking a closer look, he realized that it was indeed extremely cold and sinister, containing the Ghostly Flame of the underworld.

According to the Taoist, this thing could only be used three times. Now, there was only one time left. Thinking of the viciousness of the Ghostly Flame, Xiao Yi also put away the oil lamp.

Then, Xiao Yi walked up to the corpse and took out a storage ring from his body.

Taking a look around, he found that most of the materials were insidious magic tools, which were harmful. In addition, they made Xiao Yi's eyes light up.

He turned his right hand, and the next second, two shiny stones with milky white light fell into Xiao Yi's hand.

"Spiritual Stones? This Yinfeng Sect is indeed rich." Xiao Yi sized up the two lower-grade Spiritual Stones in his hand. He could not help feeling pleased. These two Spiritual Stone were equivalent to millions of assets in the ordinary world.

Aside from that, there was nothing valuable in his storage ring. The rest of the Foundation-building Realm cultivators were short of money. Other than some low-level spirit materials and magic treasures, there was nothing else that Xiao Yi could use. Xiao Yi threw all of them into the micro world.

After dealing with all this, Xiao Yi frowned slightly, but he remembered what Feng Laodao had said before. He not only completed the mission given by the Sect Master but also obtained a Haotian Stone mine by accident. This proved that Feng Laodao had finished the task of the Yinfeng Sect, and it had nothing to do with the Haotian Stone mine vein.

What kind of mission was it then?
