Even a monk who is also in the first level of the Transcendent Realm, may not be able to withstand Lu Ping's sword.

However, the stone gate in front blocked this powerful sword with extremely high hardness.

At the same time, this also caused Bishui Linghu to escape, temporarily getting rid of Lu Pingan's pursuit.

However, Lu Pingan detected with the devouring system that the Bishui Linghu did not go too far, but stopped some distance away.

Lu Pingan guessed that this might be due to the serious injury of the Bishui Linghu. After reaching a safer place, he relaxed and fainted.

After learning this fact, Lu Ping'an became more at ease, as long as Bishui Linghu was still nearby, he would still have a chance to kill him.

Hum!

The Hidden Edge Sword made a deep sword sound, and then a large amount of devilish energy rushed out, quickly condensing in Lu Ping'an.

In a blink of an eye, the majestic Devil Mountain sword took shape.

"I want to see if you can handle my trick!"

After saying this, Lu Ping'an raised his sword and swung it, and the Demon Mountain's sword force slammed into the stone gate.

There was a loud bang, as if the entire underwater underground palace was trembling, and even the blue lake above it caused turbulent waves.

However, in the midst of the dust, Lu Pingan clearly felt that although the stone gate received a strong impact, and even some cracks like cobwebs appeared, the whole body did not collapse, and it still stood firmly there. .

Lu Ping'an was surprised, but did not give up, once again condensed the magic mountain sword power, and also used the "double strengthening" function of the swallowing system.

The power of the Demon Mountain's sword power is even stronger, and with the power full of destruction, it once again collides on the stone gate!

Boom!

The underground palace trembles, the lake is swelling, and the impact of these impacts has become more intense.

However, Shimen basically remained the same as before, except for a few more cracks, no other changes occurred.

"It's not all right?"

Lu Pingan was surprised by this, this sword was almost his strongest move, but he still failed to break through the stone gate, which made him feel a little helpless.

But the next moment, Lu Ping'an was in those cracks, feeling the faint fluctuation of spiritual power.

Lu Ping'an was startled, and then he perceived it carefully, only to realize that there was a formation in this stone gate, but it was more hidden.

"It seems that if you want to break this stone gate, you still have to figure out the formation first."

Although Lu Pingan has not studied the formation method in depth, he still knows a little bit after all.

So, he stretched out his hand and placed it on the cold stone gate, using his spiritual perception to analyze the formation rules.

After a long time, Lu Pingan withdrew his hand and sighed helplessly.

Just because this formation is extremely profound and mysterious, it is more complicated and difficult to understand than the "Big Dipper formation" he knows.

"It would be great if Tian and that guy were here, now he should have enough ability to crack this level of formation."

Tian He has been inherited from Master Zuo Qiuli for several months. With his talent and potential in formation, he must have learned a lot from it, and he must have learned something now.

But for Lu Ping'an, it is simply as difficult to break this formation.

Therefore, he decisively gave up this idea, instead of wasting time and energy in the field he was not good at, he might as well raise his cultivation level quickly and break it forcibly.

After all, no matter how strong this formation is, its endurance is limited.

However, Lu Ping'an did not rush to do this. He thought that anyway, the Bishui Linghu stopped on the other side of Shimen and would not move in a short time. It was okay to put this matter aside first.

Compared with the beast core and bloodline of the Clear Water Spirit Tiger, the other things in this underwater underground palace are also quite tempting.

Most of those things are stacked on the ground very randomly, as if the original owner of this place didn't care at all.

Lu Pingan stepped to the pile of things closest to him, waved his hand, and blew away the thick dust accumulated on it.

Immediately afterwards, a lot of spirit stones of good grade appeared in front of Lu Ping'an, exuding strong spiritual power fluctuations.

Lu Pingan swept away with his spiritual sense, and quickly calculated the total value of these spirit stones, which was roughly equivalent to three hundred high-grade spirit stones on the ground.

"I don't know which senior stayed here, anyway...thank you!"

Lu Pingan said with a smile, waved again, and put all the spirit stones into the storage bag.

After speaking, Lu Pingan walked to the next pile of things.

This time it was not a spirit stone, but a variety of magical artifacts, ranging in quality from the yellow-level low-grade to the ground-level high-grade.

Although Lu Pingan didn't have any needs in this regard, he did not hesitate to include all these artifacts.

After all, all these things add up, they are still quite valuable, so you can bring them back to the Eastern Continent and sell them.

In the process of storing the artifacts, Lu Ping'an suddenly found two scimitars, top-grade objects on the ground floor, with excellent materials and excellent workmanship, as thin as cicada wings.

"This thing is quite suitable for Feiqiong. Go back and let her try to say something."

As soon as the voice fell, a magical artifact in Lu Pingan's storage bag had induced fluctuations.

Take it out and see that it was the sound transmission instrument that Chunyu Feiqiong gave him.

After Lu Ping'an injected spiritual power into it, he heard Chunyu Feiqiong's voice resounding from it.

"Lu Pingan, are you okay? Why did you disappear after hitting it?"

"Don't worry, I'm fine, but the water tiger is not easy to kill. In order to chase it, I ran to a strange place."

Chunyu Feiqiong said: "Weird place? There is no danger, right?"

Lu Pingan said: "At present, there is nothing dangerous, but there are a lot of good things. It should be a treasure trove left by the predecessors."

Chunyu Feiqiong said: "Oh? Isn't this a good thing then?"

Lu Pingan said, "Of course, you and the villagers should be fine, right?"

Chunyu Feiqiong said: "It's safe and sound."

Lu Pingan said: "That's good, you can take them back to the village now, because the water tiger will definitely die here, it is impossible to run out to harm others."

Chunyu Feiqiong said, "Okay, I see, you should be careful and come back early."

After putting away the sound transmission instruments, Lu Pingan continued to search the things in the underground palace ruthlessly.

Before long, Lu Ping'an put a few piles of spirit stones and magical instruments into his storage bag.

Then, he saw something different.

There are several large boxes neatly placed together, all with formations on them.

But its formation was relatively simple, and it took Lu Ping'an some time to crack all of them.

After opening it, I saw that it was full of books. To be more precise, it was all kinds of exercises, spells, formations, and beast control.

Lu Pingan took out a few casually and looked through it, and found that there were not only various classics from the Eastern Continent but also from the Western Continent.

Moreover, some are still known to Lu Pingan, ancient books that have been lost for many years on the eastern continent.

As for those in the Western Continent, Lu Pingan did not understand, but it must be similar.

As Lu Pingan put these classics into his bag, he thought from this that the original owner here should be a group of people who came together from the east and west continents, but they didn’t know why they were all gone. After that, only an underground palace and various things were left.

Had it not been for Lu Pingan to chase the green water spirit tiger here, I don't know how long it will take before anyone can find these lost things.

However, Lu Pingan didn't want to send these classics back to the Sect where they were originally located.

Regardless of the fact that some sect forces have long since died, even if they still exist, this will be a troublesome matter.

Of course, if there is a chance in the future, Lu Ping'an is still willing to return the property to the original owner and give others a favor.

After collecting all the classics, Lu Ping'an walked to the next pile of items, his eyes lit up, his mouth raised slightly, and a smile appeared.

Just because the pile of things in front of him were all beast cores, he naturally valued the blood in these beast cores more than spirit stones.

After some tests by the Devouring System, most of them failed to meet Lu Ping's requirements, but there was still a small part that made Lu Ping'an very satisfied.

But he didn't rush to devour it, but moved on, putting all the things in the underground palace hall into his pocket.

In the end, a rough calculation shows that the total value of the spirit stones plus beast cores obtained by Lu Ping'an is roughly equivalent to more than fourteen high-grade spirit stones of the ground!

The value of those magical implements and exercises is not easy to estimate, but Lu Ping'an feels that it is worth at least a few thousand high-grade spirit stones of the ground.

Like those ancient books that have been lost for many years, they may be invaluable to certain sect forces, so this situation is another matter.

Lu Pingan only got so many things to chase down the green tiger, no matter how he looked at it, he made a lot of money, which is tantamount to a huge fortune!

He was naturally very happy about it, but he didn't get too smug. He quickly calmed down, sat cross-legged on the ground, and then took out some beast cores...

This time he was not trying to swallow the blood in it, but to use it to carry out the "main bloodline upgrade."

When he was in Yunjianmen before, in order to prepare for the Four Kingdoms Grand Tournament, Lu Ping'an had already upgraded his own blood to a middle-grade ground-level.

And now he got a lot of beast cores with high-attribute bloodlines here, and there are many different attributes, and even extremely rare light-attributed and dark-attributed bloodlines, so he took advantage of the trend to have this idea.

But before that, he still needs to use another function of the phagocytic system-to increase the body's bloodline attributes.

After all, Lu Ping's body bloodline is all five elements, with only the most basic five element bloodlines. Now he has two bloodlines with rare attributes. Of course, he needs to add to his bloodline first, and then perform a comprehensive upgrade.
