Lin Feng's eyes slowly narrowed as he felt the agitation from the intense excitement of the Blue Gla.s.s Heaven Flame. An excitement he had never felt before completely flooded his entire person.

Taking a step forward, he entered the corridor.

Silence!

A deathly silence!

The moment he stepped into the hallway, an unprecedented feeling of tranquility engulfed Lin Feng's body.

This feeling was as if he had entered a state of selflessness while cultivating.

"Phew …" "Bang, bang …"

Apart from the continuous sound of breathing and the faint sound of heartbeats, the silence was so quiet that it made one's hair stand on end.

Even Lin Feng couldn't help but take in a deep breath of cold air, as his entire person gave off an unprecedented feeling of heaviness.

"I wonder, where does this serene corridor lead to?"

"I wonder how dangerous this place is?"

"Lin Feng did not continue to move forward.

However, just as he was about to ponder in his mind, a loud sound came from behind him.

"Clang!" "Clang!"

Something heavy seemed to have landed on the ground.

Lin Feng's reaction was extremely fast, almost at the same time that a loud clanging sound came out, he had already turned around.

"This... Where did this boulder come from? "

The entrance to the tunnel had disappeared and was replaced by a wall of boulders.

That feeling of hardness made him suddenly have an illusion. It was as if after being refined and upgraded, the Chaotic Element Flying Sword s that had reached the level of peak-level spirit weapon would lose their l.u.s.ter.

Above Lin Feng's flesh, a powerful aura instantly erupted.

The moment this aura exploded out, the force from the attack started to wreak havoc on the two walls of the corridor, causing a loud sound of objects colliding with each other.

"Boom!"

A punch with the full strength of his body was thrown out. The entire long corridor was filled with violent energy, as if there was a torrent of energy rus.h.i.+ng in from the end of the corridor.

In the span of a breath, the enormous stone wall blocking the entrance was swallowed up by the torrent.

This punch from Lin Feng, was enough to destroy mountains, cut off rivers, and shake the heaven and earth.

However, when it landed on the enormous stone wall, it only swayed slightly. It was like the ripples caused by raindrops entering water. It was so small that it could be ignored.

Lin Feng squinted, his expression serious.

Even with the might of his physical body, a single punch was unable to cause the slightest bit of damage. He was unable to imagine just how hard such a huge wall was. It was at least a hundred times stronger than the meteorite.

"I would like to see how hard it can be."

"Bang, bang bang …"

He did not know what the huge rock was made of, but even with Lin Feng's current strength, after using all the strength of his fleshly body and smas.h.i.+ng down with punch after punch, there were only loud explosions from the huge rock.

Aside from that, it didn't cause any damage to the wall of the giant rock. However, under Lin Feng's all-out attack, the frequency of the stone wall faintly trembled, which only increased by a few degrees. Other than that, there was nothing else.

"Hiss!"

Lin Feng could not help but take in a breath of cold air.

Just a single punch was enough to destroy a steel battles.h.i.+p's aircraft carrier. Even a nuclear bomb could rely on its physical body to take it head-on. Under the might of such a terrifying fleshly body … It was unimaginable just how terrifying the toughness of the giant rock wall was!

"Primordius!"

Taking back his train of thought, Lin Feng summoned the Chaotic Element Flying Sword into the air.

Chaotic Element Flying Sword who had already been promoted to the peak-level spirit weapon level, were comparable to peak treasure in terms of hardness. As for its sharpness, even when compared to Middle Grade Treasure, it was not inferior by much.

The piercing light had lit up a part of the dark corridor to a certain extent.

However, even though these sharp lights wreaked havoc on the stone walls and stone walls on both sides, they did not cause any damage to them. Not to mention the shocking scratches, even the shallow scratches that looked like nails were not left behind.

"It really is hard!"

The moment Lin Feng failed to break through the huge rock wall even after he used all his strength to emit his physical body, he already knew how hard the walls in his room were.

However, the hardness of the stone walls on both sides of the corridor was unexpected.

"Buzz!"

The sword trembled and a hundred meter long sword light shot out. It was like a pillar of light that shot into the sky, directly shooting toward the enormous stone wall.

"Kacha, kacha …"

The sound of swords shattering filled the air.

Even when the Chaotic Element Flying Sword landed directly on the huge rock wall, it would only produce the sound of metal sc.r.a.ping against metal, causing sparks to fly.

However, when the sparks dispersed, there wasn't a single trace left on the huge stone wall. It was as if the flying sword had never sliced through it.

"Now that things have come to this, I can only continue."

Lin Feng mumbled to himself as he turned around. He no longer paid any attention to the enormous stone wall that sealed the entrance up.

The long and serene corridor was extremely dark, and didn't have the slightest hint of light. However, with Lin Feng's current strength, he could have long since done it.

The two walls on both sides of the corridor were carved with countless images. Below them, there were even notes.

"Grand Yi True Scripture!"

"Eight Desolations Shattering Palm!"

"Tianxuan Sword Art!"

"Limitless Sword Region!"

From start to finish, Lin Feng never stopped in front of any kind of cultivation technique.

Whether it was the immortal arts he cultivated or the immortal arts he grasped, all of them were the most powerful immortal arts from his Nine Layered Heavens to the entire starry sky. The immortal techniques carved on the two sides of the wall were completely unable to enter his eyes.

However, in front of this set of imprinted cultivation techniques, Lin Feng found quite a few corpse and bones. All of the corpses, without exception, were the bones of cultivators, and they were all at least at the aurine stage realm.

Cultivators, after stepping into the Aurous Core stage, would have incomparably hard bones. Unless the physical body was directly destroyed, after the body dies, apart from the muscles rotting away into nothingness, the bones would still be able to survive for tens of thousands of years.

"It seems that before me, there were already many people who came to this serene corridor and trained in the techniques carved into the stone walls."

"Unfortunately, you guys don't know that every celestial spell isn't something you can casually cultivate. Even cultivators of the same cultivation level can't. If you're not careful, you might die!"

Lin Feng shook the diagram, gently sighed, and continued to walk forward.

Pa.s.sing through the area created by the cultivation technique, a picture in the shape of a red lotus appeared in front of him, causing him to stop in his tracks.

"This is …" "Red Lotus Fire!"

Lin Feng couldn't help but exclaim out loud. Within his trembling voice, his entire body was trembling uncontrollably.
