As far as the eye can see, Longyuan Mountain is crowded with people, and it is very lively.

On the outskirts of Longyuan Mountain, quite a few soldiers were stationed to cordon off the surroundings to prevent ordinary civilians from breaking in.

The masters of the various sects, and even some lone rangers who almost never appeared on the rivers and lakes, all appeared in this Longyuan Mountain.

On the nearby mountain peaks, some black dots could be seen standing in the sky, and these people seemed to be the powerhouses of the Heavenly Extreme Realm.

The two settled at a crack location, Xu Ruoyan looked at the criss-crossed cracks around him, as well as the hole-like openings, "The mountains and rivers here are extremely complex, and it is not easy to find the entrance to the underground palace." ”

"You don't have to worry about this, there are a large number of masters of the two realms of righteousness and demons gathered here, among which there are many capable people who are proficient in formations, even if the entrance is too deep, it will eventually be found."

Ling Chen looked at the terrain in all directions, "And there should be a lot of entrances to this place, but it will take some time." ”

"Look, then, where we should start."

Xu Ruoyan knew that Ling Chen knew a little bit about Qimen Dunjia, and where this entrance was, maybe Ling Chen would be able to see something.

"That's it."

Ling Chen pointed to a huge crack in front of him, and in the depths of that crack, there was a yin qi that only belonged to the ground coming out, and when he had just chosen a landing site, he specially chose it near here.

Hearing this, Xu Ruoyan also looked ahead, the crack in front of him was indeed deep, there was no light, and then looked at many other entrances, each entrance, there were many martial artists occupying, and there were many people who had already entered the depths of the crack and began to explore.

"Let's go."

While she was still hesitating, Ling Chen had already stepped into the crack and walked into the depths.

Xu Ruoyan only hesitated for a moment, and then followed.

……

Under the cracks, the air is very cold and extends in all directions.

After going about a few tens of meters deeper, the surrounding rock walls began to become wet.

Tick tock!

Water droplets dripped down from the sky above the rock wall and landed on the ground, and soon Ling Chen and Xu Ruoyan's clothes were wet.

"Be careful!"

Suddenly, Ling Chen grabbed Xu Ruoyan.

Rumble!

The stone cave in front of him suddenly collapsed, and pieces of rubble fell down, blocking the way.

"It's dangerous!"

Xu Ruoyan's face changed slightly, if Ling Chen hadn't reacted quickly just now, I was afraid that she had been hit by these boulders, and being injured was a trivial matter, if she was trapped, it would be terrible.

"How did you know it was going to collapse?"

Xu Ruoyan looked at Ling Chen with some surprise, the collapse just now could be said to be without warning, at least she didn't notice it at all.

"There's a little bit of mental power, and there's a little bit of intuition."

Ling Chen can now perceive the movement within a range of five hundred meters around him, and in addition, his sword dao realm is already approaching the level of "Sword Heart Clearing", after truly reaching this level, he can predict good fortune and evil, and now, just this little situation can still be dealt with.

"So which way to go now?"

The road ahead has been completely blocked, and it is obviously not realistic to continue moving forward.

"I can only turn back first, and then choose another way."

Ling Chen has roughly understood the regular structure of this underground passage, and there must be more than one entrance, since this road is not passable, there must be other roads nearby that can be passed.

After retreating to the previous fork, Ling Chen chose another underground cave and continued to go deeper.

The terrain of the entire Longyuan Mountain is complex, and if you want to find the entrance to the underground palace, you need to be patient enough.

After groping for about half a day, Ling Chen and Xu Ruoyan finally came to the depths of the ground.

What appeared in front of him was an underground lake, but who was very shallow, probably to the position of Ling Chen's chest, but Xu Ruoyan, the water level was probably at the position of his neck, and it was very inconvenient to move.

"The water is getting deeper."

Feeling the shocking chill under him, Ling Chen felt as if his body was about to freeze.

But fortunately, they have all reached the realm of the Great Grandmaster, and on the outside of their bodies, they can hold up a true qi shield to drain the lake water and ensure flexibility in the water.

Sneer......

Suddenly, there was a slight strange noise in the water.

Ling Chen's sense of hearing was so keen, when the strange sound was gradually approaching, Ling Chen also followed the sound, only to see that under the cold water, a black shadow was quietly and rapidly approaching the two of them.

The black shadow, with black legs, was dark and the size of a python, but it was not a python, but a centipede.

"It's a tin centipede!"

Ling Chen's complexion changed slightly.

The iron centipede, known for its poison. The venom that spewed out could easily poison a great grandmaster powerhouse. Of course, the Great Grandmaster and the strong should not be stupid enough to swallow this venom into their stomachs.

However, venom is also corrosive. Even some divine weapons will be corroded out of a hole.

If it were a human body, it would not be able to withstand this kind of corrosion.

In addition to the venom, the iron centipede's defenses are also amazing.

Ling Chen didn't expect that this was an almost lifeless underground lake, and there would be iron centipedes.

"Let's go."

Xu Ruoyan has also heard of the name of the iron centipede, this kind of strange beast, once it is entangled by it, I am afraid it will be extremely troublesome.

"I'm afraid it's too late."

Ling Chen's brows couldn't help frowning, this is in the water, no matter how fast they are, they can't be as fast as the iron centipede, even if they use light skills to walk on the water, they can't go far, not to mention, the ground is extremely dark, once they move too fast, it is easy to hit the stones.

"It's coming!"

Don't let Ling Chen think too much, the iron centipede was like a flying snake, suddenly speeding up under the water.

With a gleam in his eyes, Ling Chen pulled out the Cloud Hidden Sword, and then plunged into the water and swam in the direction of the iron centipede.

To deal with the underwater beasts, you must not stay on the water, otherwise, if any attack falls into the water, the power will be greatly reduced, and it will be even more difficult to hurt the underwater beasts.

"Reckless fellow!"

Xu Ruoyan saw that Ling Chen did not retreat but advanced, and also gritted his silver teeth, and also dived into the water, and then swam with Ling Chen like a beautiful mermaid in the deep sea.

Under the water, there is a lot of resistance, Ling Chen can see the appearance of the iron centipede clearly, the other party's whole body is protected by the iron shell, only a few places, the gap between the shell and the shell, there, should be the weakness of this beast.

Without thinking too much, Ling Chen had already stabbed out with a sword, and the sword qi split the water flow into two halves, accurately piercing into the junction between the shell and the shell.

Poof!

The tip of the sword stabbed into it smoothly, but after only one point, it was stuck there, unable to penetrate half an inch.

"What?"

The tip of the sword was stuck, and Ling Chen was also taken aback, how could it be so hard even in such a place?

"You don't even know where the weakness of the iron centipede is, so you attack blindly, you're really stupid enough."

Xu Ruoyan's voice suddenly came from behind him.
