After a few days, the boy left the place, and they could come back.

"Hehe, this old man has a lot of eyes. ”

Li Heng saw Yang Qi's expression when he left clearly, smiled, and said to himself: "I want to go in, do I need any map?"

He unfolded his spiritual consciousness and covered the mountain in front of him at an altitude of about 500 meters.

It's just that he didn't completely infiltrate the spiritual sense, so as not to disturb the zombie and make it wake up in advance, in case it regains its peak strength, it will be bad.

How many stones there were on the surface of the entire mountain, how much each stone weighed, and how many animals there were on the mountain, he knew everything in an instant.

The location of the entrance to the cave is halfway up the mountain, extremely secret, if there is no map or Li Heng searches with spiritual sense, it is difficult to find it at all.

The thicker the corpse qi contained in the air, the surrounding flowers and trees gradually died, and the dense pale white gas slowly enveloped the entire mountain, Li Heng felt a pang in his heart, and said secretly: This zombie is about to wake up.

He leaped forward, his figure flashed slightly, and he was halfway up the mountain.

Li Heng stretched out his hand and pressed down an inconspicuous bulge, and three feet away, a mechanism sounded, and a piece of uneven ground cracked through it, revealing a red iron ring.

This iron ring is the key to enter the cave.

He pulled out the iron ring and ascended to ...... The whole hill shook violently, but after a moment, it became quiet again.

Halfway up the mountain, an oval-shaped black hole was exposed, extremely dark and bottomless, and when the entrance of the cave was opened, a surging corpse qi rushed straight to Li Heng's door.

This corpse qi is the most vicious, it likes living creatures the most, whether it is a human or an animal, as long as it is poisoned by the corpse, it will die immediately within a moment.

If the corpse qi gushing out of the black hole spreads to the village, it will be enough to turn the village of Nuoda into a dead city in half an hour.

Although Li Heng was not afraid of this bit of corpse qi, it was not easy to be poisoned by the corpse, he closed all the pores of his body, and brought his hands forward, exuding a pure cyan true yuan power, and collecting all the corpse qi.

The corpse qi is a supreme yin thing, and after mixing with the pure true element, it immediately rises violently, tumbling in the cyan ball, like a turbulent wave, ready to break out of the ball.

Li Heng held down the cyan sphere, and a steady stream of true yuan crossed in, and the corpse qi imprisoned in it seemed to have encountered a great enemy, and the ups and downs were even more violent, and even Li Heng's body trembled.

"Calm down!"

Li Heng slammed his hands hard, and the cyan ball burst out with a "bang", and the turbulent air waves spread out in all directions, blowing the surrounding boulders down repeatedly.

As for the corpse qi that can poison people, it has also been melted by Zhenyuan.

The black hole continued to emit corpse qi outward, but it was already insignificant, and it was dissolved by the natural laws of heaven and earth in a few breaths, and it could not be dispersed to the village bed.

Although the entrance of the cave was deep and did not have the slightest luster, Li Heng had such eyesight, his eyes flashed with a faint blue light, and he looked straight down.

"Ho!"

The cave was far deeper than Li Heng imagined, with his eyesight, he could barely see the ground, he estimated that it should be more than three thousand meters deep, the cave was full of corpse qi, the group of martial cultivators fortunately went away, otherwise only this surging corpse qi would make them all die.

When Li Heng jumped down, he blocked the entrance of the cave with a boulder, so as not to fight with the zombies later, let the corpse qi leak out, and cause unnecessary casualties.

"Hea-hee!"

Every time he descended a hundred meters, he waved his hand and popped up a white flame, which clinged to the cave wall and did not go out.

By the time Li Heng descended to the bottom of the cave, the originally dark cave had become brightly lit.

The white flame was not an ordinary thing, but the heavenly fire he used to condense the incarnation at the beginning, which could not only illuminate, but also slowly dissolve the corpse qi.

The corridor was not narrow, enough for more than a dozen people to walk side by side, and Li Heng had only taken a few steps in front when he saw several stenching corpses.

"Well, men die for money, how can you come to this place?"

Those corpses were the few young people he met at noon, their skin and flesh had already been corroded by the corpse qi at all, if it weren't for the corpse qi that was not so strong at noon, they would have died when the cave entrance was opened.

But they were able to climb down from the entrance of the cave, which was a big surprise to Li Heng.

He didn't bother with the dead now, and his spiritual sense slowly stretched forward, carefully guarding his surroundings.

After walking for about half an hour, the corridor became more and more spacious, and there was no poison infested, but he still didn't dare to take it lightly.

"Huh?"

A large vermilion iron gate appeared in his line of sight, the iron gate was huge, about ten zhang high, completely blocking the road, and a trace of corpse qi gushed out from the iron gate, surprisingly did not spread, only lingering at the door.

I don't know how many years this vermilion gate has existed, and a desolate and simple atmosphere greets you, but the gate is not rusty, but faintly shining with an unknown luster.

And above the gate, there was a living creature pressed by black pressure, slowly squirming, Li Heng looked at it, and couldn't help but shudder in his heart.

Seventh-order dark creatures, vampire bats.

This is a powerful demonic beast, although it is very small, only the size of a palm, but it has the strength of a seventh-order demonic beast, each of which can rival a tenth-rank martial cultivator.

And on this gate, there are thousands of vampire bats.

Li Heng didn't move, these bats didn't move either, countless pairs of eyes flashing with bloodthirsty light stared at him, these seventh-order demonic beasts seemed to treat Li Heng as a delicious meal.

"I don't know how many years this door has existed to give birth to thousands of vampire bats, and the monster behind the door is only afraid that it will be so powerful that I can imagine it. ”

When Li Heng saw so many vampire bats, he immediately understood in his heart that the dormant zombies in this mountain range were not just born zombies, it was more likely that the legendary Li Heng hesitated for a moment and decided to take the risk and give it a try, if he could subdue a flying zombie and walk in the alien cultivation world in the future, he would not have to worry about safety, and in the future, he would openly break with the Seven Great Sects, and he could also let the flying zombie envoy summon the zombie clan and increase his own strength, this temptation, he couldn't resist.

Moreover, even if he was defeated, he could rely on the dragon-like hundred-legged steps to escape calmly.

Thinking of this, Li Heng didn't hesitate for a moment, silently summoned the Tiger Spirit Dragon Crystal, and his eyes turned towards the vampire bat.

"Squeak....... ”

More than a thousand seventh-order vampire bats felt the killing intent that frightened them at the same time, and they all screamed in unison, flapping their black wings, revealing their blood-red fangs, and rushed towards Li Heng.

To deal with this kind of flying beast, especially in the not spacious corridor, there is no more suitable attack method than the 'Qinglian Sword Song'.

In these few battles, Li Hengda used the 'Qinglian Sword Song', and he gradually liked swordsmanship, especially the Qinglian Sword Song's graceful moves and great lethality, when this set of swordsmanship was fully displayed, there were few opponents.

Back then, there was a swordsmanship genius in the Xuanyin Demon Palace, who was a peerless woman, called Gongsun Auntie, and practiced the Qinglian Sword Song to the extreme.

"In the past, there was a beautiful woman Gongsun, a sword dance moved in all directions, the audience was depressed like a mountain, and the heaven and earth were low for a long time. ”

It is rumored in the heterogeneous world that Aunt Gongsun once danced her swordsmanship and ascended to the fairy world, leaving behind an eternal and immortal legend.

"Buzz!"

The Tiger Spirit Dragon crystal let out a low humming sound, and the cyan sword qi crisscrossed the corridor, and with a flash of cold light, it cut off the head of a vampire bat.

But since the vampire bat is a seventh-order demonic beast, of course its vitality is extremely strong, its head is cut off, and its body is still flying towards Li Heng, and streams of foul-smelling blood are sprayed in the air, and when it falls to the ground, it will make a 'silky' sound, corroding the stones into thousands of holes.

Li Heng held his breath and concentrated on taking the opportunity to practice swordsmanship, and in the end, he actually closed his eyes and killed the vampire bat only by feeling.

Swordsmanship cultivation is clear and clear, and there is one mind.

Li Heng gradually found this feeling. Flying stiff.

Fei Stiff, that is a fifth-order spirit beast comparable to a Soul Heaven Stage cultivator, has a wisdom that is not weaker than that of a human being, and can even hide his own corpse qi at the peak of his life, is not afraid of the sun, and walks the world like a normal human being, except that his eyes turn blue when he drinks human blood, there is nothing else abnormal.
