The Northern Boundary Mountain, stretching for hundreds of miles from east to west, in this mountain forest, there are many medicinal herbs and demon beasts, the more precious the medicinal herbs, the more they will grow in the depths of the mountain forest, those places that are difficult to find.

Early in the morning of this day, Xu Bing and Shen Cong got up early and set off and entered the mountains and forests.

Originally, Xu Bing only took a task jade slip, but Shen Cong said that this task only had twenty spirit stones, which was not enough points, so before leaving, he went to the mission pavilion again, and after a while of searching, he found a task with relatively acceptable difficulty.

The task on this jade slip is also to take a medicinal herb, this herb is called Lingyin Flower, and its medicinal effect is to help some people who are difficult to achieve the purpose of spiritual energy entering the body.

However, this spirit flower is slightly inferior to the phalange neck, and the task reward is only ten spirit stones. But after all, after a period of selection, Shen Cong was quite satisfied with the result of his choice.

Phalanges are generally found near rocky cliffs, while Lingyinhua is found in low-lying valleys, so if you can find a valley with steep cliffs around you, it is possible to pick both herbs in the same place.

Before leaving, Shen Cong had asked several senior brothers of the same sect about this kind of thing, and the other party told him that there would be mountains and forests within ten miles around these low-level medicinal herb sects, but there would also be some demon beasts in this mountain forest. A mortal monk like him will still be a little dangerous, so try not to go too far.

Xu Bing also knew at this time that the so-called demon beast was actually a beast in the mountains and forests, but unlike ordinary beasts, this demon beast could practice like a monk and have cultivation.

Compared to monks, demon beasts will be stronger in all aspects of physical strength, but low-level demon beasts don't have much spiritual intelligence after all, so they don't need to worry too much.

After Xu Bing and Shen Cong left the sect, they traveled all the way to the west. It is very difficult to move forward in the mountains and forests, and there are grass and trees everywhere, so the two of them often have to avoid the dense weeds when walking, or directly cut down the weeds or trees that stand in the way.

This walk is two hours. When the sun was already hanging overhead, the two finally came to a valley. Stopping, the two glanced at each other, and both saw joy in each other's eyes.

This valley is not big, from where they stand to the opposite cliff is only about a hundred zhang away, the cliff wall of the valley is very steep, if it is not for the various strange shapes of the stones on the cliff wall, and also overgrown with all kinds of weeds, at a glance, I really think that it is artificially carved.

Xu Bing and the two rested in place for a while, then took out a rope from the storage bag, tied one end of the rope to a tree on the side, and the other end was grabbed by Xu Bing, and slowly climbed down the cliff wall.

Shen Cong was also waiting in place, looking at Xu Bing from time to time, and shouted softly, "Senior brother, be careful."

The valley was not deep, and it carried enough rope to allow ice to go down to the bottom of the valley. He went straight down the rope to the bottom of the valley, and only walked a distance of five or six zhang to the left, and found the thing that Shen Cong wanted in the task jade slip, the spirit leading flower.

After putting away the herbs, Xu Bing grabbed the rope again and slowly climbed towards the cliff. After climbing a few feet high, he stopped, looked left and right a few times, and found no finger neck, he continued to climb up a short distance, looking for it again.

When he was about to climb to the top of the cliff, he finally found the herb he was looking for, the phalange neck, in a crack in the stone on the left side of the cliff.

The herb was only less than a zhang away from him, Xu Bing grabbed the rope, his footsteps were slightly harder, and he kicked to the right, and his body left the cliff directly and swung to the left.

However, just when Xu Bing's body was only an arm's length away from the phalange neck, a sudden sense of crisis made his hair rise.

At the base of the phalangeal neck, there was a snake of the same thickness, only about three or four feet long, and the color of its body was the same as that of the surrounding rock walls.

This is a phalangeal rock worm, it is not a snake, it is just a kind of worm, but its appearance is very similar to that of a snake. Ordinary finger bone rock insects only have a one-fold cultivation in the mortal body realm, and they can only cultivate up to the sixth-level mortal body realm in their lifetime.

At this moment, the finger bone rock insect in front of Xu Bing's eyes could make him feel a sense of crisis, and it was obvious that his cultivation had surpassed the mortal realm.

When the phalanx rock insect was born, there was only one section, and it was just born with a heavy body, and it lived by eating the flowers of the phalange neck. The phalanges will only bloom once every three years, and every time they eat a phalange neck flower, the phalanges will increase their cultivation.

These were all the news that Shen Cong had received when he asked those senior brothers he knew before, and he told Xu Bing all along the way.

Xu Bing had already noticed that the phalanx rock insect in front of him was more than three feet long, and there were two green rings on its body, dividing its body into three sections.

At the same time that Xu Bing noticed the phalange rock worm, the worm had also discovered him. When the two were only arm's lengths apart, the phalanx rock worm attacked.

Xu Bing saw that the body of the phalangeal rock worm squirmed slightly, and a small ripple suddenly appeared from its first black ring, which moved forward along its body.

The speed of this ripple was extremely fast, almost instantly, it turned into a circle of black smoke, and it erupted from the mouth of the finger bone rock worm, and the speed did not decrease in the slightest, shooting directly towards Xu Bing.

Xu Bing's reaction was not slow at all, and he had already reacted when that sense of crisis came. I saw that his right hand directly pulled out the dagger from his waist and thrust it into the rock wall beside him, and at the same time, his hand was also fierce, and his body stopped.

Without stopping, Xu Bing's hand holding the dagger was forceful again, and he pulled his body in the direction of the rock wall, and at the same time, the black breath spewed out by the phalange rock worm directly passed through the place where Xu Bing was just now, and after flying for a few feet, it finally dissipated into the air.

This black smoke refers to the attack method of the bone rock worm, and it is an extremely powerful toxin. This toxin is useless for cultivators or demon beasts whose cultivation is higher than their own, and the other party can resist it with their own aura, but if their cultivation is lower than their own, or equivalent to their own cultivation, then they will not be able to resist this toxin, and it only takes more than twenty breaths of time for the poisoned person to be eroded by the toxin, leaving only a pile of white bones.

Compared with many demon beasts of the same level, this finger bone rock insect is a little smarter, and there are only one or two phalange stone insects in the mortal body realm within ten miles of the sect, but now there is a mortal body triple rock worm here, but it made Xu Bing almost suffer a big loss.

Xu Bing didn't stay idle after dodging a blow, his right hand grabbed the dagger, his left hand stretched forward, and the exorcism technique followed, grabbing a stone in front of him, which was directly smashed at the finger bone rock worm.

The bug seemed a little angry when he saw that he missed the blow, and even chose to fight back after dodging his own attack.

It could feel that the monk in front of it was inferior to its own cultivation, but the other party still dodged its attack, which made it grow its mouth and let out a cry that no one could detect except itself.

But when he was venting, he saw that the stone had arrived, and he opened his mouth again and spit out a circle of black smoke at the stone, and then, when the smoke collided with the stone, the skull-sized stone turned directly into a pile of powder, and before it fell, it was blown away by a gust of wind.

One person and one worm go back and forth, and after a few fights, no one side wins. When the phalanx rock worm was about to spray poison again, it suddenly stopped and turned its head to look at the phalange neck on the side.

Xu Bing was about to make a move, but when he saw that the insect turned around, he also looked over.

At this time, at the top of the phalange neck, a gray-white flower bone had already appeared, and after seeing this flower bone, the phalange rock worm had already left Xu Bing behind, jumped up directly, and bit off the flower bone in one bite and swallowed it.

After eating the flower bone, the phalangeal rock worm left at a very fast speed, scurried to a rock peak a few zhang away, and drilled directly into it.

Xu Bing put down the raised palm and swung it to the side of the phalanx neck again, only to find that the phalanx neck was intact, but the flower bones that had just grown were eaten by the insect.

However, he was tasked with finding the phalanx neck, not the flower, so he ignored it, plucked the phalange, put it in a storage bag, and then climbed up the valley.

When Xu Bing climbed up from the valley, he looked left and right, but he didn't see Shen Cong's figure, and when he was about to look around, a fireball the size of two or three heads suddenly galloped towards him from the tree on the side.
