In the blink of an eye, Ren Fan's figure disappeared in front of the cave, and even his breath could not be detected.

"Ren Fan!

Yukitsuki shouted several times in front of the cave, but received no response.

She reached out and felt her way towards the cavern, only to be blocked by the colorless barrier.

Xue Yue understood that maybe this was an opportunity that only belonged to Ren Fan, so she sat not far from the cave, patiently waiting for Ren Fan to come out.

At this time, just in front of the cave, a rock the size of a millstone suddenly opened its eyes and looked in the direction of the cave, with a hint of anticipation flashing in its eyes.

Then, the rock closed its eyes again, as if the previous scene had never happened.

Ren Fan opened his eyes, but found that he did not appear in the cave, but was in a white world.

He felt it carefully, and found that the aura here was very thin, mixed with some inexplicable power!

This is the power of the formation!

After Ren Fan touched the barrier, he didn't really enter the cave, but entered the world of the formation!

In other words, the secret hidden in the cave may be in the formation!

Ren Fan urged his spiritual power to test it, and found that he couldn't break through the shackles of the formation and leave it.

If it comes, it will be safe, and the next moment, Ren Fan calmed down.

If this formation was easy to break, it would not be his turn to pick up this bargain, and it would have been taken away by the powerhouses of the Land of Ten Thousand Demons!

Ren Fan walked all the way, and after walking for a long time, he saw a square altar.

The altar is three meters in size and has a transparent crystal ball in the center.

At this time, the surface of the crystal ball is dull, as if it has lost its essence.

Ren Fan circled around and didn't find any mechanism that could be opened, and finally he locked his eyes on the crystal ball.

"It's a blessing or a curse, it's a curse that can't be avoided!

Ren Fan thought about it again and again, and finally decided to try to export spiritual power to the crystal ball.

He jumped onto the altar, reached out and grabbed the crystal ball, and punched a piece of spiritual power.

After the crystal ball was nourished by spiritual power, it suddenly bloomed with a light blue light.

The next moment, the figure of an old man with white eyebrows floated out of the crystal ball.

The old man was not a soul, but a phantom, and after he appeared, he looked at Ren Fan and showed a kind smile.

Immediately, he said slowly:

"The old man has experienced a hundred battles in his life, challenged countless masters in the middle region, and has not tasted defeat, and is known as the undefeated Sword Sect!

"The old man stepped into the martial arts, and the establishment of this formation has been waiting for the arrival of the destined person, young man, you are the first person to come here, the old man hopes that you can pass the exam and get the old man's years of accumulation and kendo inheritance!"

After the Undefeated Sword Sect finished speaking, he disappeared into the crystal ball again.

Subsequently, the crystal ball began to be embedded in the altar. A moment later, a stone room appeared in front of Ren Fan's eyes.

Ren Fan pushed open the stone door, only to see that the stone room was empty, but there was a line of small characters engraved on the wall.

"This is the first level, the second level is after the stone gate, and you can enter the next level by splitting the stone door!"

This level tests Ren Fan's attack power, and in front of Ren Fan, there is indeed a closed stone door.

Ren Fan walked over and pushed hard, but he didn't move, and suddenly, he understood that he could only use swordsmanship here, and it would not work with other forces.

At this time, the Flame Soul Infinite Sword had not yet been completely repaired, Ren Fan took out the Ben Thunder Sword and slashed out a dazzling sword qi towards the stone gate.

"Boom!"

The sword qi slammed into the stone gate, and then disintegrated, but the stone gate did not leave even a shallow trace.

"It's such a hard stone gate, it seems that this pass is not easy to pass!"

Ren Fan frowned, and began to run the Dragon Marrow Sutra, preparing for the next sword.

After a breath, Ren Fan swung his sword again, and this time he directly cast the Heavenless Sword Duel!

One after another, the sword qi condensed in his chest, and he was neatly suspended in mid-air.

At this moment, Ren Fan's momentum changed greatly, and a lawless aura filled the entire stone room.

Ren Fan's clothes are windless and automatic, and his powerful momentum seems to not even look at heaven and earth.

The next moment, Ren Fan suddenly swung his sword and slashed towards the stone gate, and dozens of sword qi condensed into a thick sword qi in an instant, slashing out fiercely!

"Boom!"

The sword qi struck the stone gate, and the powerful force caused the entire stone chamber to begin to shake.

For a while, the stone room stirred up confused smoke and dust, blocking Ren Fan's performance.

"Scatter!"

With a low roar, the smoke and dust that filled the room suddenly stopped, and the granular dust was clearly visible to the naked eye.

Ren Fan waved his hand and swept away all the smoke and dust. At this time, Shimen still did not move, as if the sword just now had not hit.

"Such an evil sect?"

Ren Fan's pupils shrank, the Heavenless Sword was his strongest sword move at the moment, the sword just now was already Ren Fan's full blow, but not even a gap in the stone gate had not been opened!

At this moment, Ren Fan's mood began to fall, he didn't expect that his swordsmanship would be so unbearable in front of the Undefeated Sword Sect!

If you want to leave this place, you can only pass the test! Ren Fan has no confidence to break the formation set up by a martial arts powerhouse!

After adjusting for a while, Ren Fan began to show the swordsmanship he knew one by one, but those swordsmanship were not even as good as the Heavenless Sword, and the result was all the same, and he couldn't open the stone gate at all!

"Thirteen kills of Lone Peak!"

Ren Fan was practicing swordsmanship, and he was not discouraged, and showed the last swordsmanship martial art!

The Thunder Sword cut through the space, and a lonely aura arose spontaneously, exuding from the stone room.

Subsequently, the thirteen solitary peak sword qi all bombarded the center of the stone gate!

"Squeak!"

Suddenly, there was a strange sound at the junction between the stone gate and the stone room, and under this sword, the stone gate actually opened a gap!

However, the gap narrowed, and after a few moments, the stone door closed again.

"Could it be that this level tests not only the attack power of the swordsmanship, but also the comprehension of the artistic conception?"

Ren Fan discovered this key point, and a thoughtful look appeared on his face.

So far, he has comprehended a total of two artistic conceptions, the first is the artistic conception of Lone Peak, and the second is the artistic conception of sadness that he has recently comprehended!

Although Ren Fan comprehended the artistic conception of Gufeng earlier, for the artistic conception of Gufeng, he has always stayed at the level of swordsmanship.

Moreover, in terms of grade alone, the artistic conception of sorrow is higher than that of Gufeng!

It's just that, so far, Ren Fan has not integrated the artistic conception of sorrow into the sword moves, and he has not been able to achieve the realm of the sword with his will!
