Reach out and don't hit the smiley person.

Liu Songlin's deliberate purpose is self-evident, but Cao Chuan did not push it away because of this.

After all, the enemy of the enemy may not be a friend, but he can try to be an ally.

The purpose of the two of them was the same, they both wanted to get rid of Liu Chen when he returned to the Heavenly Spirit Academy.

So the two hit it off, even though there were conflicts in Chunsheng City before, but now they look like brothers, friends, and brothers.

Liu Chen will not return to Tianling Academy for at least two months, Liu Songlin happened to mention that he needed someone to help him find a secret realm, and Cao Chuan, who had already proposed to his master Wu Suowei to go out to cultivate, agreed to the other party's request, and was ready to go to the secret realm together to explore the treasures of heaven and earth.

······

Southern Imperial Domain, Purple Bamboo Forest Sea.

The Sea of Purple Bamboo Forest, located hundreds of miles east of the Heavenly Spirit Temple, was not a real sea, but a large purple bamboo forest like an ocean.

In addition, most of the surrounding areas are swamps, so it is called the Purple Bamboo Forest Sea.

However, the purple bamboo forest, which covers a vast area and is like a sea, does not have any demon beasts, or it should be said that even the spiritual power of heaven and earth is extremely rare, except for the beautiful purple bamboo forest, there is no place to attract monks.

But Liu Songlin came here with Cao Chuan, and solemnly assured that the secret realm he found was here, and he had marked it in advance, so that he could find the entrance to the secret realm as soon as he recovered from his cultivation.

Soon, Cao Chuan, who thought that Liu Songlin was bragging, saw the former move a weed pile with a few stones out of the way, so that a looming formation hidden under the weed pile appeared in front of him.

At the same time, Mu Qingqiu, who was in the depths of the sea of knowledge, opened his mouth and said: "This formation originated from the demon clan in the ancient period, judging from the spiritual power aura of the ancient formation but has not completely disappeared, the person who arranged this formation must be a strong man whose cultivation realm is far above the cave ruin realm, and the secret realm under the formation is definitely attractive enough, it seems that this guy is not lying, because he has the same aura as this formation." ”

"The secret realm left by the ancient demons... So why has it never been discovered? Cao Chuan asked curiously.

"It may be because the realm of the person who arranged this formation is too high, and it is difficult for the strength of the monks of the Southern Imperial Domain to discover the existence of the formation, and the formation has lost part of its function due to the passage of time, so it will gradually expose itself, so that you and Liu Songlin can take the lead."

Cao Chuan agreed with Mu Qingqiu's explanation, so he no longer bothered about how Liu Songlin found this secret realm that could be traced back to ancient times and the same period as Mu Qingqiu's life, but quietly waited for Liu Songlin to unravel the formation.

Ahead, I saw Liu Songlin take out a spell from his arms and put it above the formation, and then cut off his fingers and dripped blood on it.

As the blood infiltration spell dipped into the ground, the formation began to change.

Gray-black spiritual power continued to condense in the space behind the two of them like rising smoke, forming a bronze door that was slowly opening.

On the bronze door, which is like a substance, you can clearly see a series of demons and monsters.

Coupled with the stone lamps burning with dark blue flames rising at the same time on both sides, people can't help but suspect that this bronze door is the gate to the boundless purgatory and the hell of the netherworld.

But Liu Songlin took Cao Chuan's hand and walked to the open bronze door, and then regardless of the darkness inside the door, he jumped directly with Cao Chuan.

As the figures of the two were swallowed up by the darkness, the bronze gate slowly closed, and the formation on the ground also turned into black smoke and dissipated in the air at the same time, and everything returned to calm, as if nothing had happened just now.

Cao Chuan and Liu Songlin, who jumped into the darkness, fell to a platform under a faint cold wind.

As the two of them stood on the platform, a faint blue flame rose from all around, illuminating the space behind the door.

Looking around, compared to the bronze gate full of demons and monsters, the scenery that catches your eye at this moment seems a little ordinary, and it can even be said that it is a little less like what a secret realm should be.

Only those spirit stones of various grades scattered on the ground that had obviously not had time to be taken away could still give people the feeling that this was a secret realm.

The rest is the old palace in ruins, and the tall, but illegible stone statue that stands in front of the palace.

At this time, Mu Qingqiu's voice sounded again, but there was a little surprise in his tone.

"I didn't expect it to be his secret realm."

"Him?" Cao Chuan asked, "Who is Senior Mu referring to?" Is it the master of this secret realm? ”

"That's right."

Mu Qingqiu didn't hide it from Cao Chuan, and said bluntly: "The stone statue in the secret realm and the surrounding palace buildings give me a very familiar feeling, if I remember correctly, then the owner who built this secret realm should be "Yu Tianxing", one of the twelve demon lords of the demon clan who was respected as a sword demon in ancient times."

"The Twelve Demon Venerables? Sword Demon? Yu Tianxing? Cao Chuan asked three questions in a row.

But this time, Mu Qingqiu didn't answer all three questions, but just talked to Cao Chuan about who Yu Tianxing was.

With Mu Qingqiu's word-by-word explanation, Cao Chuan knew that Yu Tianxing, who was known as the Sword Demon, was a demon sword cultivator who had reached the supreme realm in his cultivation realm during his lifetime, and was named the Sword Demon because of his extremely high sword cultivation.

And Mu Qingqiu was once a general of the Terran Dynasty, and he also had the title of Heaven Slashing Sword God, so the two had dealt with each other several times.

To this day, even though Mu Qingqiu can't remember the past clearly, he still admires the strength of Tianxing, and also says that the sword and demon secret book cultivated by Yu Tianxing is better than the sky-slashing sword technique.

"If you can get the Sword Demon Secret Manual, I believe that your sword cultivation will definitely be able to break through to the realm of the Heart Sword immediately, and it will also be of great benefit to your future cultivation."

"But looking at the appearance of this secret realm is extremely dilapidated, it doesn't look like it has a sword demon secret book." After the Manifestation Divine Soul Phantom stood on Cao Chuan's shoulder and looked around, Mu Qingqiu sighed and said, "It's better to look around first, even if you can't find the Sword Demon Secret Archive, you can see if there are any heavenly treasures." ”

"Well, it just so happens that Liu Songlin is quite familiar with this place, so I'll follow him to see if I can find some good things."

After the conversation, Mu Qingqiu went back to the depths of the sea of knowledge.

Cao Chuan hurriedly set off to follow under Liu Songlin's shout.

The two walked step by step along the stairs in front of the platform to the palace area in front of them, and Liu Songlin also began to introduce his discovery of this secret realm to Cao Chuan at this time.
