The inside of the cave is very flat, and you can tell at a glance that it is man-made. The cave was pitch black, as if there was only one passage that stretched forward. Fortunately, Lin Mu touched the wall with one hand and held the stone as a weapon in the other, and strolled forward.

It's a little bad, it's the gust of yin wind in the cave, which makes Lin Mu more and more vigilant about this place, and the stones in his hand are getting tighter. The timing of the preparation is not right, so I can defend myself and sneak out quickly.

"What kind of breath is this? Why does it feel weird, and it's a little familiar?" The more he walked into the cave, Lin Mu smelled a breath, as if calling to himself, and pulled himself inside.

Suddenly, Lin Mu's feet stopped, he knew what the breath was. The box his grandfather gave him had the same smell as the one now.

In an instant, countless thoughts flashed in Lin Mu's heart, go back, or continue?

"Forget it, what my father left me, told me to come here, I believe him. If there is something here that can really solve my cultivation problem, it is not impossible to fight hard, it is better than being a waste for a lifetime. Lin Mu made up his mind in his heart, his eyes became firm, and he walked towards the cave that emitted a strange aura step by step.

Tapping, tapping, strengthened confidence, Lin Mu's footsteps also became steady, and the footsteps echoed in the hole, crisp and loud.

In the silent stone cave, the sound of water dripping on the top of the cave, mixed with the footsteps of Lin Mu, seems to have a little rhythm.

"Drip", a drop of water dripping from the top of the stone cave, dripping on Lin Mu's face and flowing down his forehead.

Lin Mu raised his hand to wipe off the water droplets, but at some point, his face was already covered with cold sweat, and the palms of his hands grabbing stones were also full of water.

Lin Mu's heart suddenly beat faster, and the sweat in his hands was still as good as ever, but his footsteps never stopped.

Suddenly, Lin Mu's eyes lit up, and Lin Mu subconsciously squinted his eyes and looked forward. In front of him is a huge natural karst cave, and there are several huge night pearls hanging on the top of the cave, which illuminates the entire karst cave like day, and the sudden light also pierces Lin Mu's eyes a little painful.

Inside the cave, the strange rocks are craggy, and there are stalactites everywhere, exuding all kinds of light, and the whole cave is beautifully decorated.

But Lin Mu's mind didn't stop at these, and after his eyes opened, he stared at the huge flat stone in the middle of the cave. There was a sword stuck in the stone, and the familiar aura emanated from the stone under the sword.

Although Lin Mu cared a lot about taking another sword, to be precise, he cared about that stone. But he didn't immediately go to the rocks, but looked at the cave carefully.

The whole cave, except for the night pearls on the top of the cave, and the stalactites around it, there is nothing else, everything seems so natural.

In the cave, except for the water droplets ticking on the top of the cave from time to time, it seems so quiet. In the middle of the sound, Lin Mu checked the entire karst cave neatly, except for the stones in the middle, there was nothing abnormal at all.

Lin Mu took a deep breath and cautiously walked towards the stone.

The distance is getting closer.........

When Lin Mu held the hilt of the sword in his hand, a monstrous wave-like breath pressed Lin Mu fell to the ground in an instant, the breath was so simple and so heavy, Lin Mu couldn't breathe at all, and even splashed on the sword with a mouthful of old blood.

"Buzz"

Suddenly, there was a soft groan from the sword that was still inserted in the stone, and in Lin Mu's shocked gaze, it rose from the ground and was suspended in mid-air.

However, that quaint aura, after the sword left the stone, suddenly increased again, everything was so sudden, and the second young master Lin, who was still immersed and shocked, was simply depressed and unconscious.

"What the fuck is this?

When the second young master of Zailin passed out, the sword suspended in the air caused the stalactites of the entire cave to shake non-stop, shaking the stones all the cracks.

After a long time, the sword may have been tired of tossing, and it transformed into the appearance of a root ginseng, and rushed towards Lin Mu, who was still lying on the ground, and the light flashed, and it directly entered Lin Mu's body.

Lin Mu's body shone with a burst of colorful light, and the cave looked extraordinarily gorgeous. It's a pity that no one saw this scene, and after a while, the light on Lin Mu's body disappeared.

Time passed minute by minute, Lin Mu lay motionless on the ground, if he couldn't see his chest rise and fall again, then he would really go to the Pure Land of Bliss.

The sound of water droplets in the cave, ticking and ticking, as time passed, and before I knew it, two days had passed.

"Ugh"

After two days of immersion in the cave, the original silence was shattered by a slight moan.

Lin Mu, who had been asleep for two days, slowly opened his eyes, and the first thing he saw was to look at his side.

"Hey, where is that sword?, why is it gone?" Subconsciously looking, Huo Ran got up, and there was no trace of the sword in the cave, and Lin Mu was confused for a while.

Lin Mu, who woke up from a deep sleep, only felt that his whole body was warm, and all parts of his body seemed to have endless strength, and he felt that he could smash the stones with one punch. Thinking of this, he had a little luck, not only did he have no pain in his abdomen after being trapped for seven or eight years, but the more he exercised, the more comfortable he felt, and his excitement slowly calmed down, and he could clearly feel that he was constantly absorbing the surrounding aura, slowly guiding it into his body, forging his weak body.

When this feeling that was once extremely longing returned to his body again, Lin Mu couldn't wait to cultivate it immediately. Fortunately, he was in control and knew that now was not the time.

Gathering his mind, Lin Mu looked at the cave curiously again. "What about the sword? Why is it missing? It was taken? It shouldn't be. Flew away on their own, quite possibly. ”

"Click, click. ”

Just when Lin Mu was thinking wildly, there was a slight cracking sound under his feet, which frightened Lin Mu, who was wondering, to jump to the side, staring at the boulder in front of him, only to see that it was full of cracks, and it was still slowly cracking.

"Boom"

A loud bang resounded through the cave, the boulder collapsed, Lin Mu clearly felt that the whole earth was trembling, and several stalactites in the cave with a huge sound fell down.

Lin Mu sat on the ground with a pale face, not knowing whether he was frightened or glad that he had a big life. He stared at the scene in front of him in shock, and his mouth couldn't close for a long time.

At a glance, a hole of three or four meters was exposed in the place of the stone just now, and the entrance of the cave looked in, not to mention more than ten meters, and there were two iron cables thick as the thickness of adult arms hanging next to it, shining with the cold light of pig iron under the desolate light of the night pearl.

Lin Mu turned over and climbed to the top along the stalactite, and knocked down a night pearl with the broken stones he picked up. Take the night pearl back to the entrance of the cave, trying to illuminate the cave with the night pearl, but in addition to seeing two iron cables, you can see at most four or five meters, far from the bottom of the cave.
