A continuous wilderness, stretching infinitely under the blue sky, without undulating hills and highlands, like a calm sea, the sun casts a blazing gaze on the earth, and those who are bathed in the sun feel warm all over their bodies, and when the early spring is approaching, the outside world still seems a little lifeless, while everything in the secluded world is full of vitality.

Because the aura of heaven and earth is extraordinarily abundant, the plants living in the secluded realm grow faster, and naturally it has become a hotbed of all kinds of natural and earthly treasures.

Heavenly materials and earth treasures are indispensable raw materials for refining all kinds of pills, and taking pills can make mortals become monks, greatly increase the speed of cultivation, and increase the probability of monks breaking through the realm, in fact, this is the fundamental reason why the exploration action continues to be carried out, because as long as the royal family masters the only way to obtain the heavenly materials and earth treasures, then it is almost equivalent to mastering the promotion path of all monks, and most monks have to choose to be loyal to the imperial court even for their own realm.

In order to ensure the long-term stability of the border, the Dalin Dynasty formulated a series of effective measures after the establishment of the country, and the security zone is one of them, through the continuous exploration of the secluded realm by the border army, demarcating a relatively safe area one after another, which can not only provide enough buffer zone for the various guards, facilitate the monitoring and early warning of special situations, but also expand the land of the Dalin Dynasty in disguise.

After leaving the safe zone, it can be regarded as entering the real secluded realm, Shen Dutong ordered the entire team to shrink the formation, so that the originally somewhat loose team became compact, and the overall travel speed slowed down to ensure that the convoy carrying supplies could keep up, this exploration operation to open up a new route, but there is no fortress like the Pure Spirit City for supplies, so the importance of the baggage convoy is self-evident.

At the junction of the safety zone and the danger zone, Yan Zheng saw some strangely shaped pillars, but those pillars were obviously not naturally formed, but some artificial creations, those pillars were very thick, about two people could hug each other, and there were golden lines etched on them, the lines were like the blood vessels of the human body, there were vague things flowing in them, I couldn't say what was going on, but Yan Zheng always felt that those pillars were alive, he asked Wu Chang about the last exploration operation, but Wu Chang didn't know what these pillars were used for, The only thing that can be determined is that these pillars have existed a long time ago, and now that he sees these pillars again, Yan Zheng feels indescribably weird.

At this moment, somewhere in the Netherworld, three experienced Netherworld hunters were digging the shallow pit in front of them diligently, this was a cave they found during their last exploration, there were a lot of natural treasures growing outside this cave, obviously the aura was much richer than the surroundings, because the things prepared at that time were not sufficient, so the three of them did not try to enter at that time, but covered the entrance of the cave with floating soil outside, and made a simple mark, waiting for the next time.

The royal family almost monopolized the way to obtain the treasures of heaven and earth, and strictly controlled the circulation of treasures of heaven and earth, but only those limited treasures of heaven and earth were not enough to meet the desire of countless people to seek immortals and seek immortality, so the profession of hunters in the secret realm came into being, they are generally held by people who live on the border and are more familiar with the treasures, and they do similar tasks to the tasks performed by the border army, except that they are purely for the purpose of exchanging benefits for the treasures in the secret realm, and the border army is to cover up the fact of obtaining the treasures of heaven and earth with the exploration actions on the surface.

The three of them live a job with their heads pinned to their belts, after all, the danger of the secluded realm is well known, but there must be brave men under the heavy reward, in order to be able to live a better life, there are always people who are willing to risk their lives, of course, the large amount of silver money in exchange for the treasure of heaven and earth will not let them stop there, but will be more fascinated by making a fortune in this way, after all, this way is the same as the lottery, as long as you pick up a precious enough fairy grass, the money sold is enough for a person to have no worries about food and clothing for the rest of his life, Therefore, after squandering the silver money they had obtained from collecting fairy grass last time, the three of them almost couldn't wait to return to this cave.

In less than half an hour, the three hunters dug up the floating soil on the cave, and a swarthy cave appeared in front of them, unlike the fishy smell when most of the cave openings were opened, this cave actually emitted a refreshing fragrance after opening, obviously there must be some kind of natural treasure hidden in the depths of the cave, which also doubled the confidence of the three of them to enter the cave, if they really got any rare treasures, they would not have to come to this ghost place again in the next few years.

The three hunters entered the cave one by one, the first thing that caught their eyes was a relatively wide platform, and further down was a cliff, it seemed that if they wanted to continue deeper, the three of them had to descend with the help of ropes, the hunters took out the ground nails in their backpacks, smashed the ground nails into the ground with a hammer, and then wrapped the rope around the ground nails, after making sure that it was strong, one hunter wrapped the rope around himself, tied a dead knot, and then volunteered to take the lead in traveling downward, and the other two followed, The abrupt rocks didn't hinder them too much, they just slowed down their descent to the lower platform.

After successfully reaching the lower platform, the three Netherworld hunters lit the torches, took out the blades on their waists, and moved deeper, the more they marched forward, the stronger the refreshing aroma became, tempting the three of them to keep speeding up, the three of them had entered similar caves before, compared to the surface world where they often encountered monsters, the danger factor of the underground world was much smaller, and the probability of obtaining heavenly treasures was also greater.

The three of them passed through a tunnel and arrived at a relatively wide cave hall, which had obviously existed for a long time, the stalactites on the top of the cave almost hung to the ground, and in front of the cave hall were five different tunnels, and a hunter held a torch and tested it at each tunnel entrance, and the flame on the torch shook at the mouth of one of the tunnels, indicating that there was air movement in this tunnel, and there were no dangerous gases in it.

Several people did not hesitate, and continued to move forward along this tunnel, the way forward was very smooth, they felt that they had descended a long distance, and the increasingly strong aroma kept reminding them that they were getting closer and closer to the lowest level of the cave, but as the three of them went deeper, the leading hunter of the Netherworld gradually felt that something was wrong, the tunnel that was originally sloping downward was becoming vertical, they could still walk at first, and then they had to bend down and walk slowly, and now they could only lie on the ground and slowly crawl down with the help of a pickaxe, If they continued like this, they would have slipped off the smooth rock wall, but just as they were about to despair, there was light at the end of the tunnel, and the sound of the wind kept coming from the front, and they were probably about to reach the end of the tunnel.

There was a burst of ecstasy in the hearts of the three of them, and their movements sped up a little, and they crawled down with their hands and feet, but when the leading Netherworld hunter left the tunnel and saw the scene below, he almost screamed, and the end of the tunnel was not a cave blessed land containing heavenly treasures, but an incomparably huge void!

In this huge cavity, there are countless yellow-beaked and white-winged perfumer birds, they are sleeping, the sound of the wind coming from the tunnel just now is their neat breathing, and the refreshing fragrance that lured the three of them here is actually the dung of the perfume birds at the bottom of the cave!

The other two also caught a glimpse of this terrifying scene, and were speechless for a while, the perfume bird is a less common kind of demon beast in the netherworld, after all, most of their habitat areas are in underground caves, with slender tongues like straws, they are used to living in groups, they belong to relatively weak demon beasts, only a few perfume birds will fly to the ground to forage for food when they are hungry, so even the three more experienced hunters know little about them, otherwise they will never stray into such a deep cave.

A perfumer bird is not a threat, and ordinary people with weapons are capable of dealing with it, but there are too many perfumers living in this hollow, and it is absolutely impossible to deal with it with the ability of these three hunters.

The leading hunter hurriedly signaled the other two to go back, and the two hunters also quickly climbed up with their pickaxes, but one of them could not forget the terrifying scene just now, and was frightened, and his movements were slightly flustered, and the pickaxe in his hand was not nailed into the rock wall, and the whole person fell down when he missed, but fortunately the hunter below caught him and did not let him fall, but the pickaxe he was holding just now had fallen towards the sleeping birds below.

The crisp sound of the pickaxe hitting the stone echoed throughout the hollow, and all the perfume birds were awakened by this sound, saying that they were birds, but they had lived in the cave for a long time without feathers, and between their open wings were bat-like wing membranes, they puffed out their white wing membranes, and swarmed towards the tunnel, and the three hunters of the Netherworld were instantly devoured by the birds, and countless slender tongues like straws pierced their bodies, making them instantly turn into three dried corpses, and the birds passed through the tunnel, rushed out of the cave, and flew straight to the surface.

The large army that was repairing not far away happened to be their target, and the sudden appearance of a large number of prey made the spicers chirp with joy, calling all their kind to start hunting.

Yan Zheng, who was drinking water, heard an unusual sound, which seemed to be like a large number of bats flapping their wings, followed by an aroma that was too strong and uncomfortable, Yan Zheng raised his head and looked into the distance, a large black shadow appeared in the sky that began to become dim, he immediately stood up from the ground, pulled out the three-foot long knife behind his back, and warned the entire team.

"The monster is coming!"
