Flying around the valley in the air, Mo Yuan took out the Misty Array Banner he had purchased in the Hundred Treasure Tower.

This time, he had to deal with a group of demon beasts, not a demon beast, and he couldn't be careless, so Mo Yuan deliberately bought a set of formation flags for the mist array.

Before the battle, the entire valley was shrouded with the Misty Array Banner, and in case of an accident, the Misty Array could still block one or two, although the Misty Array had only an average effect on the Tsukiji Monks, but at least it would give Mo Yuan time to react.

As for why not buy a better formation flag, one is that it is scarce, but it is expensive, and the latter is enough to discourage Mo Yuan.

As for why the array jade is not used, firstly, because the array jade has a time limit, once the spiritual energy in the spirit stone is exhausted, Mo Yuan will not be able to replenish the spiritual energy with the spirit stone in time, and secondly, because the formation formed by the array jade is not as good as the formation flag in terms of coverage area.

The valley is too big, and this is something that Jinyu can't do.

After flying around the valley and laying down the array flags one by one, soon, the fog that shrouded the valley began to roll up, surging towards the place covered by the formation, and in less than a stick of incense, the fog that originally filled the surroundings disappeared, and all of them gathered in the formation.

At this moment, Mo Yuan stood in the air, and when he looked at the valley again, he couldn't even see the outline of the valley, and the entire valley was shrouded in mist, even if he was cultivating with Mo Yuan's foundation, his vision could not penetrate this fog, and when his divine sense entered, he would be blocked by the formation, although he could forcibly probe, but this would touch the ban, and he would be known by the people who set up the formation for the first time.

Mo Yuan looked around and nodded with satisfaction, although this array of flag arrays is not as convenient as the array of jade arrays, it really has its own uniqueness.

Driving the white dragon boat to the bottom, Mo Yuan summoned the spirit sniffing snake and placed it on a big tree at the edge of the formation.

Using the method in the Soul Guardian True Technique, he gave a simple and easy-to-understand order to the Sniffing Spirit Snake.

"You are here to be on guard, if anything is wrong, enter the battle in time and inform me."

The sniffing snake looked at Mo Yuan in confusion, and after a while, he understood what Mo Yuan meant, and his little green head raised slightly, and spit out the snake letter.

The realm of the Sniffing Spirit Snake is too low, and the spiritual intelligence is not high, if it weren't for the fact that the "Imperial Spirit True Technique" has its own uniqueness in this regard, it is this simple order, and Mo Yuan would not be able to give it.

After all, this little snake is not the same as an iron-eating turtle, and Mo Yuan did not accept it as a natal spirit animal, so he could not communicate with each other.

After arranging the vigilance measures, Mo Yuan released the Iron Eating Turtle again, and after instructing him for a while, he held the unopened Huang Luo umbrella and entered the formation under the shroud of the Iron Eating Turtle Earth Spirit.

The defense of the Iron Eating Turtle Earth Spirit Cover is now no longer comparable to the defense of the light ball when Mo Yuan used the Huang Luo Umbrella.

The Iron Eating Turtle's Earth Spirit Cover is equivalent to a top-grade defensive magic weapon during the Qi Refining Period, but the same top-grade magic weapon, in the hands of a Qi Refining Monk and a Foundation Cultivation Monk, the effect it can exert is completely different.

Mo Yuan walked into the formation, took out the array disk that controlled the formation, and injected the aura, and in an instant, the dense fog in front of him began to push towards both sides, revealing a road, and as Mo Yuan walked by, the dense fog closed again, and the road disappeared behind Mo Yuan.

After a while, Mo Yuan came to the cave where the blood bat's nest described on the map was located, I don't know if it was because of the daytime, Mo Yuan stood outside the cave, he couldn't hear any sound, and there was silence in the cave.

The cave is not far from the waterfall, and you can vaguely hear the rumbling sound of the water, because of the surrounding tall trees, it seems a little dim and a little eerie.

Humid, hot, and dark, this environment is indeed suitable for creatures like blood bats.

Observing the surroundings of the cave entrance, Mo Yuan looked towards the cave again, his eyes could only see the distance of more than ten zhang in the cave, and further inside, it was pitch black, and he could only use his divine sense to explore.

It's a pity that there is no special method of cultivating the divine sense, and Mo Yuan's divine sense is only the standard of the monks in the early stage of foundation building, and it is impossible to explore all the caves by relying on the divine sense.

Looking at the pitch-black cave, Mo Yuan offered the Huang Luo umbrella, and the yellow mangs flickered, and the ball of light formed, enveloping Mo Yuan.

The iron-eating turtle looked at the ball of light, then at himself outside the ball of light, and couldn't help but look at Mo Yuan pitifully.

As soon as Mo Yuan took out the Sunset Bow and held it in his hand, he saw the extremely aggrieved gaze of the iron-eating turtle, which was both angry and funny.

"What are you afraid of! You use the Escape Technique to hide underground, and if I am not a Blood Bat opponent for a while, you will quickly run away with me. Blood bats can only fly, and they can't burrow into the ground, so they can't target you! ”

Mo Yuan patted the glans, he was very speechless at this timid turtle, he seriously doubted that this turtle could master the magic of the art of escape without a teacher, it was because he was too timid, and he mastered the technique of escape in order to run well.

Before entering the cave, Mo Yuan took out a concealment charm and slapped it on the back of the iron-eating turtle, which could restrain the iron-eating turtle's breath to a certain extent and reduce the chance of being discovered by the blood bat.

However, Mo Yuan felt that even if he didn't use the concealment charm, the blood bats might not be able to spot the iron-eating turtle.

The spirit of the demon beasts in the foundation building period is not high, they all rely on instinct to act, as long as the iron-eating turtle does not jump out by itself, the blood bat will not find the strategy of "Moyuan catches bats, and the turtle is behind".

Mo Yuan slowly entered the cave, and the iron-eating turtle dived down.

Walking into the darkness, the light emitted by Huang Luo's umbrella dispelled the darkness around Mo Yuan, which brought convenience to Mo Yuan to a large extent.

Walking seven or eight miles in the cave, Mo Yuan looked at the strangely shaped rock walls on both sides and the stalactite pillars hanging from the top, couldn't help but stop, swallowed his saliva, and sensed the location of the iron-eating turtle in his heart, and found that the iron-eating turtle was twenty or thirty feet under his feet before continuing to move forward.

After walking forward for another seven or eight miles, Mo Yuan suddenly stopped, twitched his nose, and a sour smell tightly wrapped around his nose, lingering.

"It should be almost there!"

Mo Yuan took out the concealment talisman and pasted one on himself, while using his divine sense to probe the surroundings to guard against possible dangers, and then continued to move forward slowly.

Mo Yuan no longer paid attention to the darkness around him, and focused all his attention on the exploration of his divine sense.

Soon, through his divine sense, Mo Yuan found that not far ahead, the narrow cave suddenly became open, forming a hall more than 100 zhang long and dozens of zhang wide, and at the top of the hall, sharp and slender stalactite pillars hung down, and between these stone pillars, black bats of a certain size hung upside down, and pitch-black bat wings wrapped their bodies.

Mo Yuan cautiously moved forward, and soon arrived outside the cave hall explored by his divine sense, with the light emitted by the Huang Luo umbrella, Mo Yuan saw part of the situation on the top, and looked at it, his brows couldn't help frowning slightly.

"There are too many of these blood bats."

After a slight glance, Mo Yuan's eyes quickly looked at the center of the top, two blood bats of different sizes, but obviously much larger than other blood bats, were hanging upside down, seeing this, Mo Yuan's brows instantly furrowed.

"How can there be two, didn't Tanyunzi say that there is only one third-level blood bat!"

Doubts rose in Mo Yuan's heart, but no one could answer them.

Looking at the two blood bats hanging upside down with their eyes closed, Mo Yuan felt that something seemed to be a little wrong, and the news of Tanyunzi should not have made such a big mistake.

He looked at the floor of the hall, the ground was covered with dense white bones, all of which were transformed by the bones of demon beasts, and Mo Yuan also found several human bones, as well as some body shriveled like several corpses, and the bodies of demon beasts that had not yet decayed.

Looking at these white bones covering the ground, Mo Yuan felt that his scalp was a little numb, it was the first time he had seen such a scene since he entered the Immortal Cultivation Realm.

Although I can't talk about being afraid, I can't help but feel a little creepy in my heart.

Just as he was thinking about it, Mo Yuan suddenly realized that something was not quite right there, and suddenly looked up at the place where the two large blood bats were.

I saw that in the darkness, two pairs of eyes emitting blood-red light were staring at him coldly, without a trace of emotion, motionless, as if looking at a corpse.
