"Master, this is our sect's distress signal, there must be an emergency, it seems that I need to go. Zhang Yu said a little anxiously.

He knew that if it was an ordinary situation, Lin Yan and the others would never send a distress signal, they must have encountered a situation that they couldn't solve, so they asked for help from themselves, but he was a little worried about the situation here of the master.

"You can go with confidence, with my current strength, ordinary martial arts masters are not in their eyes. Mo Chen knew what Zhang Yu was thinking, so he hurriedly relieved.

"Well, then I'll go. Zhang Yu knew that what Mo Chen said was true, and after a little groaning, he quickly ran towards the place of signal.

When he arrived there, Xiao Hei and the others had already arrived, but it was not as he expected, and he hurriedly asked, "What's the matter? Who sent the distress signal?"

"Brother Yu, it's me! ”

When Zhang Yu heard Lin Yan's answer, he also walked into a large hall with doubts.

"What the hell is going on?" Looking at the empty hall, Zhang Yu was even more puzzled.

"Brother Yu, you follow me. Lin Yan's face was full of excitement, and there was also a hint of mystery.

After following Lin Yan towards the inner hall, Zhang Yu found that there was a tunnel in the inner hall!

Going down along the deep tunnel, Zhang Yu roughly estimated that it was nearly a kilometer, but it still didn't come to the end, and in this process, Lin Yan didn't say a word.

"Lin Yan, where are you going to take us?" Zhang Yu couldn't help but ask.

"Brother Yu, don't worry, it's coming soon, when the time comes, you will be surprised. Lin Yan still did not reveal where he was going to take Zhang Yu and the others.

Hearing this, Zhang Yu and the others could only patiently continue to move forward with Lin Yan.

"Here we are, here it is. ”

As soon as Lin Yan's voice fell, Zhang Yu and the others' eyes suddenly lit up, the original narrow passage was gone, and an underground world appeared in front of everyone's eyes.

"Brother Yu, this should be an alchemy potential, go forward, it is where the Danfang is located, there are many pills there, but it is estimated that because it has been too long, the medicinal effect of most of the pills has passed very seriously, those with lower levels have been included in the storage ring by me, and there are some precious pills, all of which are guarded by the formation, I have no choice, so I sent a distress signal. Lin Yan explained.

"Those pills are right here, you see. ”

After Lin Yan brought Zhang Yu to the Danfang, Zhang Yu and the others couldn't help but gasp.

I saw that in the Nadan room, there were many stone pillars, and on each stone pillar there was a translucent ball of light, emitting a soft light.

Through the faint light, you can see that the colorful pills are spinning in it.

Between the twitches of the snort, you can smell the refreshing fragrance in the whole Dan room.

"I once broke through a few balls of light by force, and I found that the pills here are the most inferior fifth-grade pills, and because of the protection of the formation, the effect of the medicine is very small, and there are almost ninety percent of the medicinal power. With so many pills, it will take me at least a few days to get my hands on them completely, so I have to help you," Lin Yan said again.

In the entire Dan Room, there are at least dozens of stone pillars, and on each stone pillar there is an elixir above the fifth level, and the value of this batch of pills is not much lower than the value of the weapons found by Zhang Yu.

For cultivators, cultivation is the most fundamental, and only when cultivation is strong can you get everything you want.

However, after all, cultivation is against the sky, and every breakthrough is extremely difficult, and often a breakthrough in a realm requires accumulated efforts before it is possible.

However, since human beings learned to refine the elixir, there is a world of difference between cultivation and before, a small elixir, the huge effect it contains, sometimes, beyond the imagination of ordinary people.

The pills that solidify Peiyuan are the most common, and their value is naturally relatively low, but like some pills that break through the shackles and bottlenecks, their value is several times higher than those ordinary pills.

Even if they are only one-time consumables, humans often crave them more than they are.

Just a fifth-grade low-grade elixir is worth hundreds of thousands of medium-grade spirit stones, and some of them are even millions of medium-grade spirit stones.

"Everyone started to find a formation that they could break, and quickly pocketed this batch of pills. I estimate that in less than half a day, the rest of the strong people will arrive, and at that time, it will be impossible for us to be as easy as this. Zhang Yu said cautiously.

"Understood!"

Everyone whispered yes, and then quickly began to break the formation shrouded in the stone pillars in front of them, while Zhang Yu patrolled around the entire Dan room.

"This one should be the most precious elixir among them, let's get it first. ”

In front of Zhang Yu, the light emitted from this pill was the most intense, like a small sun, and the scorching light completely suppressed some of the light clusters around it.

Moreover, even with the barrier of the formation, Zhang Yu could still smell the extremely strong medicinal fragrance, inhaled it deeply, and almost reveled in it, and the feeling of tiredness above the spirit was swept away.

"Bang!"

Since Zhang Yu was not familiar with the formation, he could only break ten thousand methods with one force, hoping that he could smash this method with strong strength.

Under his temptation, this formation shook slightly, and it returned to normal. Zhang Yu could feel that the strength of the formation contained in this pill almost surpassed the formation arranged on top of those mysterious weapons.

In other words, the value of this elixir is even higher than that of the Xuanqi!

At the very least, it is also a top-grade elixir of the sixth grade, and its value is immeasurable!

"Whew. After taking a gentle breath, Zhang Yu also adjusted his breathing to calm down, and with his divine sense, he explored the flaws contained in his formation.

If he relied on brute force alone, he also had a trace of confidence, but because this was thousands of meters from the ground, while he bombarded this formation, it would also cause the entire underground palace to collapse, under such a heavy pressure of mud and stone, he might still have the possibility of escaping, but Nie Tianhua and they were indeed certain to die.

Therefore, he can only find out the hidden flaws in the formation, so that he can break this formation with the least force.

Although this formation seems to be mellow and flawless, even if it is the most perfect formation, there will eventually be mistakes in the process of layout, so Zhang Yu believes that this formation will not be an exception, as long as he can find out where the flaw is, it will definitely be easier to break it with a point.

In Zhang Yu's induction, each rune on these formations was interlocking, almost perfectly fused together, with the strength of his divine sense, after observing it several times, he didn't even notice the slightest place to start.

And in this process, Xiao Hei and the others have broken several stone pillars one after another and obtained several precious pills.

Although they also wondered why Zhang Yu didn't hurry up, they still chose not to disturb Zhang Yu and concentrated on their own business.

Two hours have passed, Lin Yan has broken through the formation above the eight stone pillars and obtained eight pills, among these eight pills, six are fifth-grade pills, and two are sixth-grade lower-grade pills, worth tens of millions of medium-grade spirit stones.

Xiao Hei, who had the highest cultivation in the field, had already obtained fifteen pills, each of which was a fine of the best, and its value was already nearly 100 million!

However, Zhang Yu was still staring at the largest ball of light, his eyes were bloodshot from focusing for a long time, but he didn't give up.

"Found it!" The hard work paid off, and finally, after more than two hours of intently watchful attention, Zhang Yu finally discovered the abnormality in the operation of the formation.

Although you are perfect in this formation, after all, too much time has passed, and after each cycle of operation, there will always be a trace of undetectable stagnation.

This stagnation time is so short, almost only one hundredth of a second, such a short time, even a junior martial sect can't accurately grasp it!

Moreover, the most important thing is that Zhang Yu found that this formation actually has a self-destructive function, so Zhang Yu has almost only one shot, once this time it cannot damage the core components of the formation, then, the destruction command contained in it will be activated, so that the elixir in it will instantly turn into nothingness.

Under this destructive force, the person who broke the formation would definitely be hit hard, because it was impossible to estimate how much of the strongest power that this formation could burst out, so Zhang Yu was not sure if this underground palace could withstand this destructive force.

"Blackie, you all stand back, I'm going to start getting ready to do it. For the sake of safety, Zhang Yu could only let Xiao Hei and the others temporarily stop their movements and retreat to the entrance of the tunnel.

"It's now, break it for me!" Seeing that everyone stepped aside according to their own requirements, Zhang Yu also burst into applause, exerting his strength to a few points, and when he was about to make a move, he made a brazen move.

The powerful energy fluctuations emanated, and everyone's hearts were cold, if it wasn't for Zhang Yu to push them away in advance, and they would definitely end up seriously injured by this aftermath.

Under the terrifying energy explosion, the pillars of light beside Zhang Yu suddenly turned into powder, and the light emitted from each light cluster was much dimmer, and when it was close, the naked eye could see that the cracks were like spider webs, making up for it.

"Click!"

A crack sounded, and Zhang Yu was pleasantly surprised to find that a fine crack finally appeared on the light cluster that was hit by him head-on, and the constantly running formation also stagnated!
