After the envoy finished speaking, the passage to the fourth floor had appeared in front of us, slowly calming down in the shaking of the earth and the mountains, we didn't dare to continue to kill the remaining time, and hurriedly walked into the fourth floor without looking back, and when we all entered, everything behind us disappeared immediately.

What appeared before our eyes was a barren world, surrounded by yellow sand, as far as the eye could see, there was a stone platform in front of us, and four stone pillars were erected around it, which were engraved with strange patterns that had never been seen before, and on each stone pillar was placed a ball of different colors, which were vermilion, azure, rhyme white and dark four colors, and when we walked into the stone platform, we saw that there was a circular groove on it according to the east, west, north and south directions, as if something needed to be put into it.

The wind swept through the overwhelming yellow sand and swept the face with a faint pain, I looked around and suddenly saw a forest white thing exposed outside the yellow sand not far away, walked over and brushed away the sand above, buried below was a dry bone, I was secretly shocked in my heart, the trials of each layer of this trial tower are extraordinary, we have now reached the fourth layer, according to the reminder of the envoy, the more you go up the trial, the more fierce it is, the people who can come here to test are the ancient gods and demons and heavenly beings, these forest white bones must also be the trialists who were trapped and died here.

Han Yu walked over and squatted on the ground to brush off a layer of yellow sand, revealing more dry bones, and gradually we cleaned up a huge skeleton.

"This ...... Who is this for? I turned my head and asked the envoy in astonishment, after all, the skeleton was completely different from what I was familiar with, and it looked like the body of a giant.

"There is more than one skeleton buried under the yellow sand, how can I distinguish between them all and dry bones." As he spoke, he walked over to the sand dunes, his gaze looking down meaningfully.

I frowned, it was clear that I was hinting at something, we stood up and walked to him, and then heard Gu Xiaoxiao's startled voice, she covered her mouth and looked down in a daze, her hand trembling and pointing to the bottom of the sand dune.

We followed her fingers to look over, and suddenly everyone was dumbfounded, I subconsciously squirmed the Adam's apple, and the corners of my mouth twitched involuntarily.

Underneath the sand dunes is a huge deep pit, the erosion of yellow sand blows through it, and the inside of the pit is piled up with countless skeletons, all of which are filled in a messy manner, and the whole pit is like an unburied cemetery, and it is impossible to tell how many corpses are buried here.

"This ...... Who left these behind? Yun Duruo asked with a trembling voice.

"Presumably a trialist who broke into the Glass Exquisite Pagoda like us, but in the end failed to get out of the fourth layer." Mercy folds his hands together and can't bear to look at them.

The front layer is full of dangers, it is a fluke to be able to walk here, and now that I see so many yellow sand bones, the fourth layer must be even more dangerous, I dare not turn around and look at the envoy in a hurry.

"You call me me, you call yourself a vassal, since you have received the law and guarded the tower, I don't expect you to help, you always have to explain what kind of place this is, and how is this layer of trial?"

Seeing that my voice was stern, the envoy buried his head again and respectfully told us that the fourth layer of the glazed Linglong Pagoda is known as the land of oblivion, and the place where we are standing now is the ancient desolation before the beginning of Hongmeng, of course, this is not the real ancient desolation, with the beginning of the realm of the ancient being gradually forgotten, this is just the illusion of the desolation.

Buried under the yellow sand were the ancient gods and demons who could not break through the fourth layer, as well as countless heavenly beings, who were trapped and died here and eventually turned into white bones.

"What exactly is the trial of the fourth layer, and how can you pass this trial?" Gu Xiaoxiao asked nervously.

"Put the four divine beads on this stone pillar into the groove of the stone platform, and the trial of the fourth layer will be passed." The envoy walked back to the stone platform we first saw, pointed to it and said to us.

"It's as simple as that?" Yun Duruo pursed his lips and asked in surprise.

If it is really so simple, how can there be so many ancient gods and demons and heavenly beings trapped and killed here, I now know very well that there is no simple thing in this glazed exquisite tower, these gods and demons buried in the yellow sand may be any more powerful than us now, and in the end, there can only be a handful of dry bones left.

The envoy should have seen my doubts, hesitated for a while or said it, he told us that the divine beads on the stone pillar represent the four directions of the ancient flood and desolation, each free and guarded by the four gods, and if you want to reach the divine beads, you must go through the tempering test of the four gods.

"Quartet God? Does it refer to the Qinglong Mengzhang Divine Monarch, guarding the East; The White Tiger Guards the Divine Monarch and guards the West; Lingguang Shenjun, guarding the south; Xuanwu holds the name of the god monarch and guards the north. Han Yu frowned, and then quickly stretched out again. The four gods are also known as the four spirits, and it shouldn't be a problem to deal with the four spirits with our abilities. ”

"These four gods may not be the Green Dragon, White Tiger, Vermilion Bird and Xuanwu you said." Gu Xiaoxiao squatted in front of the stone pillar and stared at the pattern on it for a long time, and said meaningfully.

"These are the four gods of Taoism, what else can they be if they are not these four spirits?" Han Yu asked in amazement.

Although Gu Xiaoxiao's mastery of Xuan is far less profound than Han Yu's Taoism, the Taoist origin and history have long been familiar with Gu Liancheng's edification, she pointed to the southern stone pillar for us to see, the pattern lines inscribed on the stone pillar where the vermilion bead is placed are simple and long-lasting, and the erosion of the yellow sand is a little blurred and incomplete, but the pattern on it can still be seen, and the pattern outlines a giant covered in red fire, holding a handful of flames in each of his left and right hands, and stepping on two flying dragons on his feet.

Han Yu was also a little dazed after reading it, the Taoist Quartet God is in charge of the affairs of the south, but the appearance of the Vermilion Bird is familiar to all of us, and it is completely different from the carving on the stone pillar.

Gu Xiaoxiao walked to the stone pillar on the west side, on which was placed a white divine bead, and in the inscription pattern below, it was a fierce god holding a double axe, a person with lightning and thunder behind him, a long snake hanging on his left ear, and two flying dragons under his feet, the Taoist guardian of the west was a white tiger, and the pattern we saw was clearly a majestic and vicious giant.

Then walk to the stone pillar on the other side, the direction here represents the east, and the one who guards the east among the four spirits is the green dragon, but it seems that the dragon with the revered status here is just a sacred object used to step on the flight, and can be easily controlled by those unknown giants.

The stone pillar on the east side is a pitch-black orb, and in the pattern below we clearly recognize a giant human-headed monster with a bird-like body that has never been seen before, also trampling two flying dragons under its feet.

The last thing left is the stone pillar that places the azure divine bead in the north, in the pattern we did not find the Xuanwu guarding the north in the four spirits, only in the blurred pattern to see a monster with a blue human head and snake body, standing on the back of a huge turtle majestically cruising in the ocean.

"The four gods here are not the four spirits of Taoism at all!" Gu Xiaoxiao slowly opened her mouth after reading it, and said in surprise.

"Then what are the four gods here?" Han Yu asked puzzled.

"You say this is the forgotten land, the ancient desolation forgotten by the world?" Gu Xiaoxiao didn't answer Han Yu, but turned to the envoy and asked seriously.

The envoy nodded affirmatively.

"The ancient flood famine existed before the beginning of Hongmeng, it was a world where gods and demons coexisted, since it was an ancient flood famine, the gods who guarded the Quartet were of course also ancient gods and demons." After Gu Xiaoxiao finished speaking, he walked to the stone pillar located in the east and pointed to the pattern on it and said to us. "My grandfather once told me that before the realm was first decided, the god in charge of the east was Ju Mang, who was one of the ancient gods and was also known as the Emperor of the Quartet."

Han Yu's body shook suddenly, his mouth slowly opened, and he looked at the stone pillars around us with a surprised expression, and the corners of his mouth squirmed a few times, and he said in a panic.

"My master also told me that the human body and human head in the pattern on the stone pillar of the East are stepping on the double dragon, and it is recorded in the Flood Wilderness that there is a god in the East, with a bird body and a human face, and two dragons...... The pattern on this pattern should indeed refer to the ancient gods! ”

"Jumang?!" This name is unfamiliar to me, but I can guess something by looking at Han Yu and Gu Xiaoxiao's expressions. "And what are the other Four Emperors?"

"If I'm not mistaken, the emperors of the Quartet of the Flood Wilderness should be, Zhurong in the south, with a beast body and a human face, with two dragons, and a snake in the left ear, with two dragons, and then Yujiang in the north, with a black body and siblings, and two dragons." Gu Xiaoxiao thought about it and blurted out.

"Zhu Rong, Ju Mang, Harvest and Yu Jiang......" I repeated the four names in Gu Xiao's novel in my mouth, all of which were the first time I heard them, and then looked back at the white bones exposed in the blown yellow sand, how many ancient gods and demons trapped and died here should not be able to pass the ancient trial, I subconsciously licked my lips, in fact, until now I still can't imagine what is so powerful about this Quartet God Emperor, compared to the ancient flood is really long for me, no wonder this place is called the land of forgetting, I think many people are like me, The fear of the ancient gods and demons has been forgotten.

"You just said that if you want to get these four divine beads, you will have to go through the tempering of the four god emperors, you ......" Han Yu wanted to speak, but stopped looking at it in shock, causing it to take a long time to finish speaking. You don't mean to say let's challenge the Divine Emperor of the Quartet of the Flood Wilderness now, right?! ”

"The glazed Linglong Pagoda is the tower of trials, and the trials here are all tempered and tested, not to mention that this is not a real ancient wilderness, but this represents that the divine beads of the east, west, north and south are stored in the area ruled by the god emperor of the four directions." The envoy shook his head unhurriedly and said calmly. "I won't let you challenge the ancient gods and demons, if it's the real Emperor of the Quartet of the Flood Desolation, don't say you, even the Heavenly God Buddha Daluo Golden Immortal of the Nine Heavens may not be able to compete with it, there are only a handful of people who can defeat the God Emperor of the Quartet of the Desolation, but there are two of you who can do it."

"There are two?!" I looked at the envoy in amazement.

The envoy nodded, and after glancing around our faces, he said meaningfully.

"Of course, the Hades Emperor Netherworld is one of them, and as for who the other is, if you can get Yugui, you should know soon."
