Early morning.

A round-faced old man in a white robe and black-haired shawl was flying in the air without hurrying, and even so, his flight speed was still very amazing, much faster than that of a spirit infant monk.

His divine sense covers a radius of thousands of miles, and he is always on the lookout for any suspicious objects within two hundred feet underground.

"Found you!"

The old man suddenly muttered to himself, and his flight speed suddenly increased by half, and in a moment the figure disappeared into the sky.

Flying nearly a thousand miles away, the old man stopped above a hundred-zhang high hill, turned his hand and took out a cyan three-foot long sword that looked very ordinary, held it in his hand, and slashed at the hill.

A clear sword qi left the long sword, and instantly transformed into a hundred-zhang long cyan sword qi phantom, and it slashed on the hill in the blink of an eye.

With a loud sound like a landslide cracking, the hill was split in two by the sword qi like paper paste, and the sword instantly sank dozens of feet into the ground.

In a simple cave more than a hundred zhang deep directly below the hill, Lin Feng's heart tightened, and he opened his eyes suddenly, and he felt the violent shaking of the earth.

"Oh no! it's been discovered!" he didn't even think about running the Escape Rock Technique, and his body's movement speed instantly increased to the extreme, rushing into the rock and escaping.

At this time, a cyan sword qi easily slashed a few zhang behind him, slashing open the cave where he was living, and extending dozens of zhang deep sword qi into the ground before disappearing.

"Hmm, this little thief's escape technique is really exquisite, and he can easily dodge my sword qi. ”

The old man in the air raised his eyebrows, his face was full of surprise, and his divine sense swept over Lin Feng's body, remembering Lin Feng's breath and appearance firmly.

"This person must be a Soul Transformation Stage cultivator!" Lin Feng was startled, feeling a powerful divine sense sweep over his body.

He immediately guessed the old man's cultivation, and with his mid-stage Jindan cultivation, he was invisible, and the Soul Infant Monk and Ben couldn't find him.

His body continued to descend twenty or thirty zhang while moving forward quickly, and when he went deeper into the underground rock for more than one hundred and fifty zhang, his body could no longer continue to sink.

"The Escape Rock Technique has reached its limit!" Lin Feng felt that the spiritual power was passing rapidly, and in this way, the spiritual power would be exhausted in half an hour.

"Oh, the art of retreat has reached its limit, then you will come out for the old man!" the old man muttered to himself, waving the long sword in his hand and slashing at the ground in front of him.

With a loud bang, the earth suddenly cracked a gap that was a hundred zhang long and ten zhang wide, and the sword qi broke through the hard rock and cut into the ground, slashing towards Lin Feng, who was traveling quickly.

In the hard rock underground, Lin Feng's divine sense was almost twenty zhang, and by the time he sensed the sword qi, the sword qi had already reached the front of him.

Lin Feng's pupils shrank violently, and his mind was in a hurry, and the speed of the Escape Rock Technique, which had already been used to the extreme, was strangely half a minute faster, narrowly avoiding this sword.

Cold sweat had already broken out on Lin Feng's forehead, with his current physical strength, he couldn't resist the blow of the Soul Transformation Stage cultivator.

"It's kind of interesting, see how long you can hide...... It's time for you, little one, to get out and do something. The corners of the old man's mouth curled.

He slapped a fist-sized black spirit beast bag around his waist, and a small worm like an earthworm flew out of it.

But in the blink of an eye, the small insect became a large insect with the thickness of a three-zhang long water tank and slightly pointed at both ends.

The whole body of the large insect is jet black, the rough and very hard skin slowly wriggles, and the whole body is covered with a layer of slimy black liquid, which looks very disgusting.

The "Hiss......" The two ends of the worm parted at the same time, revealing two large mouths full of triangular sharp teeth, and it made a high-pitched and piercing hissing sound, which sounded very excited.

"Go, get that thief out of the ground, you can't eat him as a snack. The old man casually pointed to the ground in front of him and commanded.

The big worm received the order, hissed excitedly again, and writhed its fleshy body and fell to the ground.

Then, a strange scene happened.

With a muffled pop, the body of the big insect touched the hard rocky ground but was not flattened, and it sank into the ground in an instant, and the rock disappeared in an instant as if it had been evaporated, leaving only a bottomless stone cave with the thickness of a water tank and repeated black smoke.

The old man followed the big insect with his hands behind his back and calmly, flying in the air unhurriedly.

Ground floor.

Lin Feng was anxious in his heart, and his thoughts turned sharply while fleeing quickly, thinking about how to get rid of the pursuit of a Soul Transformation Stage cultivator, but he couldn't think of a good way for a while.

"Remnant Soul! Remnant Soul ......" Lin Feng called out loudly in his heart, but Remnant Soul still didn't respond.

At this moment, a large black worm suddenly appeared within the range of his divine sense.

"It's ...... High-level Demonic Beast!" Lin Feng's complexion changed drastically, and he felt the spiritual pressure equivalent to the Great Perfection cultivation of the Jindan Stage on the big insect behind him.

What surprised him the most was that the big worm shuttled through the hard rock as if it were flying in the air, and any rock that came into contact with the slime on its body was instantly corroded into a small amount of black smoke.

Lin Feng had already raised the speed of the Escape Rock Technique to the extreme, but the big insect was still slowly approaching foot by foot, and it didn't take a stick of incense to catch up with him.

Lin Feng wiped the cold sweat from his forehead and quickly thought about what to do.

In the hard rock, the Nether Moonlight Blade and the Blue Drop can exert less than one percent of the combat power on the ground, and they can fight against the great insects that could not compete with the strength of the Great Perfection of the Jindan Period.

In a few moments, the big worm was already five feet behind him, opening its large mouth to reveal the spiraled teeth in its mouthparts, and let out an excited hissing sound.

No matter how Lin Feng changed the direction of his progress, the big insect always chased after him like a maggot on the tarsal bone, and he swore not to give up if he didn't swallow Lin Feng into his belly.

Lin Feng took out three bottles of spiritual power recovery potion and poured it into his mouth, he had to maintain sufficient spiritual power at all times, the soul transformation stage monk released a big worm to chase him, just to force him out of the ground and catch him.

On the contrary, if he is not careful in the fight with the big worm, he will be attacked by the Soul Transformation Stage Monk, and he may die faster.

Just when Lin Feng was in a dilemma, a voice that he was very familiar with sounded in his mind.

"It's ...... You kid is lucky to have encountered this rare magical beast, and it's a high-level ......."

"Remnant Soul! I have been discovered! What is this monster of the Rock Transformation Silkworm, it is the pet of a Soul Transformation Stage cultivator!" Lin Feng quickly interrupted the remnant soul's words, and explained in a solemn tone.

"What?" the remnant was startled.

"I've been locked by that Soul Transformation Cultivator's divine sense, and I can't escape with the Escape Rock Technique. Lin Feng said quickly, and glanced back, the Transforming Rock Silkworm was still less than three zhang away from him.

The remnant soul was silent for a moment, and said quickly in a solemn tone, "It seems that only using it can help you escape this fate...... You get back to the ground, and immediately press the buckle knocker on the person who opened the door, and use the trick to run as fast as you can. ”

"I will find the right time to pass on to you the magic of driving the dark door, you must always listen to my command, remember! Don't hesitate to move quickly, we only have one chance!"

"Okay!" Lin Feng didn't even think about it, and suddenly changed direction and rushed towards the ground.

"Oh, it's coming out!" the old man raised his eyebrows, and the corners of his mouth curled.

At this moment, Lin Feng suddenly rushed out of the ground, and the Rock Silkworm rushed out of the ground after him, leaving a hole in the ground emitting black smoke.

The clouds under Lin Feng's feet pulled out a series of afterimages from his body, and in just a few blinks of an eye, he escaped hundreds of zhang away, and his speed was much faster than that of ordinary spirit infancy cultivators, throwing the Rock Transformation Silkworm far away.

"What kind of escape is this...... The speed is so fast!" The old man muttered in surprise, looking at Lin Feng's distant back, the old man took three or four breaths.

"Well, you can't catch up with him in the air. ”

The old man came back to his senses and beckoned, and the Rock Silkworm hissed reluctantly, quickly shrunk and flew back into the spirit beast bag on the old man's waist.

"Hmph, little thief, when the old man captures you alive, he will definitely search the soul to get your escape technique. The old man snorted coldly, and flew out like an arrow off the string, and his speed was instantly raised to the extreme.

Lin Feng, who was fleeing quickly, took off the bracelet without hesitation and pressed it into the groove in the front of the door opener, and the door opener and the door knocker flashed at the same time.

Suddenly, his eyes went dark, but after a few moments his vision returned to normal.

"I have passed on to you the magic that drives the Dark Gate, and you must remember to take it back as soon as you enter it. ”

"I remembered!" Lin Feng replied in his heart.

He quickly glanced back and saw a round-faced old man in his sixties wearing a white robe, with black hair and a shawl, less than two hundred feet away from him.

"Little thief, you can't escape!" The old man waved his sleeves, and a large silver needle about the thickness of an arm's length of two feet stabbed Lin Feng's back like lightning with a silver ray.

"Shoot with all your might! Activate the Dark Gate at the same time!Leave the silver needle alone!" the remnant said loudly and quickly.

Lin Feng's divine sense locked on the old man behind him, he paused his figure, and violently waved his hand to shoot a three-zhang long light blade behind him.

He didn't even look at the blade of light and the rapidly flying silver needle, he threw the dark door in his hand into the air, and raised his hand to send a black light into the dark door.

The dark door was full of black light, and it grew to the size of three zhang in a rapid rotation, and the diameter of the hole in the middle also became one zhang large.

Lin Feng saw that inside the hole of the Dark Gate was an endless and dark void, as if as long as he walked into that void, he could travel through time and space to reach two worlds.

He was just about to drive the clouds into the void when he heard a muffled pop.

Without a pause, the silver needle pierced through his back and into his chest, bringing out a line of blood several feet long, leaving an arm-thick blood hole in his chest, and a mouthful of blood spurted out of his throat sweetly.

"What's that?" the old man's eyes widened in surprise, looking at the rapidly rotating black ring not far in front of Lin Feng.

Suddenly, the old man raised his hand and slapped a palm in the air, and an earthy yellow palm print with a size of ten zhang and a thickness of one zhang appeared in front of his palm out of thin air.

There was a loud click, and the palm print collided with the rapidly flying light blade, and while the light blade collapsed and disappeared, it left a three-zhang long and half-zhang deep crack on the palm print, almost cutting the palm print through.

"I want to run!" the old man didn't have time to think about it, and pressed his palm forward hard.

The earthy yellow palm print moved three points faster, and the void where the palm print passed was violently twisted, slapping towards Lin Feng with a rumbling sound.

This time, the old man made a dead hand, and he had a hunch that as long as Lin Feng was allowed to enter the black ring, Lin Feng would be able to escape.

But the old man was still a step too late after all.

Lin Feng used his light blade to attack the old man in order to attract the old man's attention, he did not dodge the non-lethal attack of the silver needle, but also to buy a moment to activate the dark door.

He endured the sharp pain in his chest and plunged headlong into the dark door, which quickly shrank and shrank, turning into a black point of light in the blink of an eye, and then vanishing without a trace.

The palm print passed through the void where Lin Feng disappeared like lightning, and slammed into a small hill, with a loud boom, the ground shook and the mountains shook, most of the hill was razed to the ground, and countless pieces of rubble flew out more than ten miles away.

The dense smoke and dust were scattered with the wind, and the old man looked at the void in front of him, Lin Feng and the Dark Gate had disappeared within his divine sense, leaving no trace.

"That black ring must be the sacred relic of our courtyard!" muttered the old man with a look of astonishment.

He felt an extremely faint amount of dark energy on the Dark Gate, and he had only felt the existence of this energy from the holy relics of the academy since he cultivated his path.

"It can actually drive the holy relics of our hospital to break through the space and escape! And that black light blade can actually cut through the old man's palm print! What is the origin of this person?"

The old man's eyes lit up, and he felt that there must be a big secret on Lin Feng's body.
