In the mountains and forests on the periphery of the Tianzang Mountains, the trees are shady, the light and shadow are swaying among the trees, and a young man with a sword and a basket on his back is pacing slowly.

Usually cultivators who go into the mountains to collect medicine or hunt are either in a hurry, or they are attentive and nervous about the surrounding situation, but this young man is humming a little song leisurely, chattering about a grass stalk on his lips, and walking and stopping, completely in the posture of swimming in the mountains and rivers in this dangerous forest.

Cultivators or hunters who pass by, seeing them from afar, all take a detour and regard them as aliens. But if anyone can see the young man's eyes, the concentration in them is surprising, a state of full concentration and no distractions.

This son is Yunlin, although he is humming a small song in his mouth at this time, his mind is not on the song.

About two or three miles ahead, a jade-tailed heron hovered left and right, its eyes constantly scanning downward, the hunters on the road, the slightly larger beasts in the forest, and the spirit grass growing in the horns, all of which could not escape the glance of the jade-tailed heron.

Between a mile and five miles behind, there was also a bird patrolling, but this was a small oriole, which patrolled quickly, but stared only at pedestrians or large beasts.

Higher in the mountains and forests on both sides, a black eagle with a wingspan of three feet hovers up and down, passing through the forest from time to time, and the sharp eyes keep sweeping through the forest, and everything in the forest is carved into the eagle eye.

On the forest path, Yunlin will rush to one side of the forest whenever there is no one nearby, and every time he scurries, there will be a harvest, either a first-grade spirit grass, or a second-grade spirit grass.

In less than two hours since entering the mountain forest, Yunlin has harvested five second-grade elixirs, and there are more than a dozen first-grade elixirs, and most of these elixirs are stored in the soul ring space, leaving only two first-grade elixirs in the back basket.

Along the way, except for a few hunters who acted alone or cultivators who collected medicine, Yun Lin never met with groups of more than two people. There were a few times when Kankan met a group of people for a few breaths, and Yun Lin ran into the forest on the road in advance.

Yunlin walked all the way to a towering stone tablet without any danger, the tall stone tablet towered into the clouds, engraved: "Fifty miles of boundary" four big characters, iron and silver hooks, revealing an amazing momentum. People were forty or fifty zhang away, and they still felt a sense of depression under the hood, which made Yun Lin feel a little uncomfortable.

Looking at the huge stone stele, Yun Lin pondered for a long time and decided to stop there, but turned around and walked through the mountain forest on the side. Beside the route he took, a looming red line connected the base of the stone monument and headed far into the forest, and on the outside, a path formed by people stretched out and disappeared into the depths of the forest.

Yun Lin chose this route with his own considerations, the fifty-mile boundary is an important boundary of the Tianzang Mountain Range: inside, the demon beasts whose strength is in the Yuanjue Realm will appear frequently, and even the demon beasts under the Yuanjue Realm are mostly in groups. Legend has it that entering the Yuanjue realm will lead to nine deaths, which is the ordinary Yuanjue realm, and entering the fifty-mile realm is also full of dangers.

Although Yunlin's current strength has doubled, he is not arrogant enough to dare to go deep into such a dangerous situation, although for the sake of training, he still stays away from places where there are many defeats and few victories. It is said that the fifty-mile realm is said to have made thirty-six giant monuments by the great power of the predecessors, and the thirty-six giant monuments are connected by mana, enclosing the core of the Tianzang Mountain Range in a circle, so that the demon beasts that are too powerful cannot come out. The monsters that occasionally leak out are also slightly weaker individuals to protect the safety of the residents outside the mountain range.

After a moment's thought, Yun Lin walked along a red dotted line emanating from the root of the giant monument. This line is not a physical object, but only a trace of light and shadow, faint, it is said that the thirty-six monuments are connected by such a red thread. The effect of the red line is to prevent powerful monsters from crossing the border from the inner realm, and to protect the inhabitants outside the mountains.

It seems that there are not a few cultivators who have the same thoughts, and there is a path that has been stepped out along the red line, looming among the barren grass and trees.

Along the way, Yun Lin was very curious about the faint red line, such a dotted line, how could the space prevent the powerful demon beast from breaking out of the boundary?

"Whew!"

A jade-tailed heron plummeted down from a high altitude, its wings swept lightly, and it swept gently past the red line.

The faint red line seemed to be nothing, and there was no reaction, and the passing emerald heron did not drop even a single feather!

"Strange! Could it be that this red line does not live up to its name and has no effect?"

Yun Lin was puzzled, bent down and picked up a stone piece or two fingers wide, and with a flick of two fingers, the stone flakes whistled towards the red line!

Almost in the blink of an eye, the stone shards crossed the red line with a sharp roar, and nothing unexpected happened. A hint of disappointment flashed in Yun Lin's eyes as he watched the stone flakes fly towards the dense forest within the fifty-mile boundary, only to see the stone flakes shoot down a few green leaves and disappear into the woods.

"Poof!"

After a long time, a slight muffled sound came faintly from the direction where the stone flakes were swept away.

"It seems that this stone chip shoots far enough!

Yun Lin's face bloomed with a self-satisfied wine vortex, and he was very pleased with his cultivation during this time.

"Roar!" An earth-shattering roar came from the direction where the stone pieces landed, and Yun Lin's hairs stood on end, his pupils constricted, and he suddenly pulled out his long sword from behind his back and stared straight in the direction from which the sound came.

From this sound, it can be judged that the one who roared must be a demon beast that has experienced extreme harm, and a single roar can make Yunlin, who has been trained to the eighth layer of the Yuan Beginning, tremble, at least equivalent to a second-order demon beast above the Yuan Jue Realm. When a person encountered such a terrifying demon beast in the forest, Yun Lin's heart couldn't help but hang, and the right palm holding the sword was sweating unconsciously.

"Whoa!" flocks of birds flew from the dense forest.

"Whoosh!whoosh!whoosh!" A flock of hares rushed out of the depths of the forest.

Before he could see it, it was the wind wolf that rushed out and swept in the direction of Yunlin, and the red line did not react to the wind wolf at all. Yun Lin even raised his sword to fight, but the wind wolf ignored him and swept away from close range, making Yun Lin, whose heartstrings were tense, secretly rejoice.

But the next scene made Yun Lin, who had just breathed a sigh of relief, almost jump out of his heart!

"Beep, beep!" rang out from the dense forest, and I saw some small trees the thickness of an arm breaking and falling, not to mention the grass and shrubs that were a man tall.

Then about a dozen iron-scaled pigs with single horns and hard scales rushed out of the forest in shock, and the direction was where the cloud forest stood!

Iron Scale Pig, a first-order eight-rank demon beast, is equivalent to the strength of the eighth-layer cultivation of the cultivator. A hard-scaled sword is difficult to hurt, the single horn on his head is extremely sharp, and the general iron shield can be pierced under the extremely fast sprint, but its speed is also amazing, and even dodging is quite difficult, so even if it is a strong person in the Yuanjue Realm, it is a headache. But in the same way, the single horn and hard scales on this pig are all high-grade refining materials, which are worth a lot of money!

This iron-scaled pig can barely cope with a Yunlin encounter, but he encounters more than a dozen at once!

"Oh my God!"

Yun Lin let out a strange howl, dodged and hid behind a big tree hugged by one or two people, clenching his long sword with both hands, praying that the red line could stop this group of evil gods, while thinking of a countermeasure in his heart.

The expected red line was broken in an instant, and there was no reaction!

"Tread, tread, stride!"

Before Yunlin could react, these dozen iron-scaled pigs had already rushed away from the big tree where Yunlin was located, and they were unaware of the Yunlin that was close at hand, leaving only a puff of smoke and dust!

Yun Lin Chang exhaled, and the person squatted down limply.

But this is not the time to relax!

As soon as Yun Lin squatted down, there was a loud rumbling sound from the direction of the stone chips, as if there was a sound of a huge thing falling to the ground, and occasionally it was accompanied by the sound of a giant tree falling down.

At this time, even if Yunlin lacked experience, no matter how late his head was, he knew that something extremely terrifying must have happened.

"Whoosh!" Yun Lin jumped back and followed the direction of the Iron Scale Pig.

While rushing to mobilize the distraction spirit, soon the emerald heron that had crossed the red line at the beginning turned around and flew around, hovering over the place where Shicai Yunlin stood.

Yun Lin only ran a few hundred feet after the Iron Scale Pig, and the Iron Scale Pig disappeared, making Yun Lin not only marvel at the speed of the Iron Scale Pig running again and again. After flashing into a small hill and a forest path more than ten zhang away, Yun Lin saw a cave at the foot of the mountain that only allowed one person to pass through.

Leaning over to pick up a piece of gravel, he threw it, and the gravel swept into the cave with great precision, and there was a crisp sound of "ding". His eyes were staring at the entrance of the cave, and there was no movement in the middle of the sound, and there were no animals, monsters, and beasts entering and exiting the cave, so Yun Lin carried a stone slab the size of a person, and covered the slate on the entrance of the cave after he entered the cave.

As soon as he entered the cave, the cave was suddenly wide, and Yun Lin casually sat down cross-legged on a large stone, tried to hold his breath, and then quietly paid attention to the movement of the soul.

In the eyes of the Emerald Heron, I was seeing a tragic scene at the red line below, like hell on earth.

Next to the red line just now, there were the corpses of demon beasts lying on the ground, all with blackened fur and burned. What is terrifying is that these are all powerful demon beasts above the second order, and they are indeed dying here in a panic at this time.

Among them, the second-order and third-grade ice arrow wolf with green fur and steaming steam on its body is not only strong in claws and teeth, but also can spew ice arrows in its mouth. Once a person or beast is hit by an ice arrow, it freezes into ice in the blink of an eye, and the end is a disaster, fortunately, the range of the ice arrow is generally only more than a zhang, but it also makes the average cultivator frightened, and the only way for a cultivator in the Yuanjue Realm to encounter is to find a way. The demon beasts that have been so harmed, but at this time, there are enough four of them who have died here.

The Ice Arrow Wolf's clawed fangs are a precious material for refining, and the purchase price of the refining shop in the town is two hundred gold coins per claw, and one fangs are three hundred gold coins. Not to mention the ice beads on the chest of the Ice Arrow Wolf, this ice bead is an excellent aid to the cultivation of ice attribute exercises.
