Su Ping'an saw that the white ghost was about to use all his strength to deal with Ling'er, and he hurriedly shouted:

"Ling'er, defend with all your might, wait until I kill this tall man, and then I'll help you!"

"Hmm!"

Ling'er replied and summoned the blue flying sword back to her side, only to see the blue flying sword bloom with endless sword qi, turning into a sword qi barrier in front of her.

Sword vaporization shield!

The spell that Ling'er cast was the sword qi shield in the sword art of the imperial sword technique.

The white ghost drove the ghost head knife to hit the sword and shield, but was blocked by the sword and shield, and for a while he couldn't break through the sword and shield defense.

On the other side, Su Ping'an and the were originally in a stalemate, in fact, if it weren't for Su Ping'an's huge consumption of spiritual power when he opened the formation just now, the would not be Su Ping'an's opponent at all. Amaterasumen is also a first-class sect, and in the same realm, the strength of the disciples under the sect is not comparable to the loose cultivation of black and white ghosts.

"Senior brother, I can't hold on!"

Suddenly, Ling'er shouted.

Hearing that his junior sister Ling'er might not last long, Su Ping'an's hand pinched the sword technique again and again, bit the tip of his tongue, and a mouthful of essence blood sprayed on the Wind Chopping Sword, and the Wind Chopping Sword emitted a more dazzling light, slashing the black grimace. When the black grimace touched the light blue sword, it was like snow meeting the sun, and it melted in an instant.

In terms of the level of strength, after absorbing Su Ping'an's essence blood, the light blue sword light emitted by the sword was much higher than the black demon.

I saw the Wind Slashing Sword slash through the black demon with a sword, turning into a sword and stabbing at the.

"Not good!"

Seeing this, the let out a loud cry, and once again a stream of black gas erupted from his mouth, facing the sword that had been transformed by the Wind Slashing Sword.

However, how could the demon demon be able to block Su Ping'an's flying sword? I saw that the light blue sword light suddenly split into two, and one of the sword rays directly pierced this black qi and rushed towards the's chest. Another sword slashed towards the top of the's head.

Su Ping'an's sword was divided into two, and the power of each sword was almost the same as the power of the sword before the differentiation.

The was shocked by this, and was stabbed through the chest by the Wind Slashing Sword. The stared wide-eyed, then fell straight to the ground, and just died, as if he didn't believe that he would die here after years of cultivating the true realm.

In fact, if you fight one-on-one, it is not easy for Su Ping'an to defeat the, but the treats Su Ping'an as an ordinary foundation building five-fold monk, and many of his own methods are not yet available, so he is directly killed by Su Ping'an's strongest means, and he can only blame the for carelessly killing himself, otherwise he can't stop Su Ping'an if he wants to escape.

"Big brother!"

When the white ghost saw that the was killed, his face was shocked and angry, and then he shouted angrily and recalled the ghost head knife.

"You dare to kill my eldest brother, I will never let you go!"

Su Ping'an and the others thought that the white ghost was going to fight hard to avenge the. Who knew that as soon as the white ghost finished speaking, he directly used the secret method to teleport and escape outside the cave, and he didn't dare to turn his head back.

“....... It's so fast!"

Su Ping'an and the others wanted to intercept it, but it was too late.

Su Ping'an walked quickly to the corpse and pocketed the's storage bag. He has always been the most active and skilled in touching corpses.

When he put away the's storage bag, Su Ping'an took a look, and there were only a few low-grade spirit stones and some worthless things in it. In terms of value, in Su Ping'an's opinion, the storage bag of the, who cultivated as a five-fold cultivator of the foundation building, was not as good as the storage bag of a disciple of the Qi Condensation Period of the Hidden Sword Sect.

"Phew! Such a poor creature dares to come out and rob. ”

Su Ping'an couldn't help but be a little disappointed, this person looked fierce, and he claimed to be in this seat, but he didn't expect to be a poor man.

Seeing this, Ling'er said, "Senior brother, let's continue to explore this Luoyun Cave Mansion." ”

"Hmm. Su Ping'an nodded and replied.

The two of them came to the door of Luoyun Cave Mansion and pushed open the stone gate that had been closed for five hundred years.

After pushing open the stone gate of the cave, you will see a river several zhang wide, which extends to the left and right, and seems to run through the entire cave. Su Ping'an found that the river water was crystal clear and flowing, not a passive stagnant water, but should be connected to an underground undercurrent.

There is also a one-zhang wide stone bridge on the river, and across the stone bridge is the interior of Luoyun Cave Mansion. The perimeter of the stone bridge is made of white rock, the whole shape is arched, and the bridge deck is paved with a layer of cyan square bricks. The guardrails on both sides of the stone bridge are also carved with mysterious-looking snowflake marks.

"Luo Yun Zhenren's cave is very carefully arranged, it seems that Luo Yun Zhenren should be a monk with a sense of life. Su Ping'an said secretly in his heart.

Just this stone bridge and river water, it will take a lot of time for the owner of the cave to be constructed, and this is only the periphery of the Luoyun Cave Mansion.

Su Ping'an and the others walked across the stone bridge and continued to walk towards the interior of Luoyun Cave Mansion.

After crossing the stone bridge, you will see an extremely open space, and the ground is paved with a layer of bluestone slabs, each of which is carved with the same mysterious snowflake marks as on the guardrail of the previous stone bridge.

It can be seen that this Luo Yun real person is very obsessed with snowflakes.

There are only two buildings in the wide open space, and these two buildings only occupy less than a fifth of the open space, and the rest of the land is empty.

Su Ping'an secretly guessed that Luo Yun Zhenren's plan when he built Luo Yun Cave Mansion should be very grand, and he wanted to build many buildings. It's just that this Luoyun Cave Mansion has not yet been fully built, and he fell unexpectedly.

These two buildings are written "Luo Yunju" and "Library Pavilion" respectively. The purpose of the two buildings is immediately apparent at a glance.

Su Ping'an and Ling'er glanced at each other, and then walked towards the Tibetan Law Pavilion together.

The library is a two-story attic, and the first floor of the library has a stone table and several stone chairs, but there is no collection of books.

The two walked up the stairs to the second floor of the library pavilion, and saw that the second floor was densely packed with bookshelves, and the bookshelves were neatly filled with books, I am afraid that there are tens of thousands of books!

This Luo Yun Zhenren has a collection of quirks, why did he collect so many books?

Su Ping'an and the others looked at the room full of books, and their breathing became a little short. This is the collection of Jindan period monks, in case there are a few Xuan-level exercises or spells in it, it will be considered a profit for Su Ping'an and the others.

The two of them quickly walked to the bookshelf, took out a collection of books from the shelf, and looked at it.

Most of the paper used in these books in the Xiuzhen Realm has been specially treated and can last for thousands of years to be immortal.

Su Ping'an took out a book, only to see that there were two big characters "Journey to the South" written on it, and he didn't know if it was an exercise or a spell. Su Ping'an opened this "Journey to the South", but the content in it made him stunned, only to feel a little familiar, it was all about a monk riding a horse with three apprentices, and the story of encountering various monsters on the way to the south to learn scriptures, and the pages next to it were accompanied by exquisite pictures.
