The array in front of him is indeed not an immortal array, the highest level, but only a ninth-level spirit array.

However, the technique used in this array completely surpassed the ninth-level spirit array, and even surpassed the arrangement technique of the immortal array master.

The huge formation in front of him was apart from a huge, incomparably subtle ninth-level spiritual array that isolated the divine sense.

It also includes, the ninth-level concealment formation, the ninth-level divine consciousness attack formation, the ninth-level killing array, and the ninth-level trapped formation......

In short, all the formations added up to tens of thousands, and so many formations fused with each other, there was no gap at all.

It seems to be a complete formation, such a subtle technique, Lin Mu believes that even if the immortal array master of the immortal realm comes down, he may not be able to arrange it so perfectly.

However, the more perfect this formation is, the greater the difficulty it will cause to the cracking of the forest trees.

Because this big array is a whole, it is obviously impossible for Lin Mu to crack one by one.

However, with Lin Mu's formation cultivation at this time, and his own strength cultivation, it was obviously impossible to crack tens of thousands of ninth-level formations in one fell swoop.

Lin Mu looked at the dense formation in front of him, and he also had a headache.

I know that there are good things in it, but I just can't get in, which makes people anxious.

"There is!" Lin Mu suddenly thought of himself, a sentence he saw on "Array" might be able to solve the current situation.

According to the "Array", the most basic thing for any formation to operate is the provision of aura.

If you don't have enough aura to provide, no matter how exquisitely your formation is arranged, it's just an ornament.

Just like this exquisite formation, if you take it to the earth, I am afraid that if you run it, it will drain all the aura of the earth, and then this formation will directly break itself.

And the tens of thousands of ninth-level spiritual arrays in front of him obviously have a larger source of spiritual energy, if Lin Mu can find this source of spiritual energy, he may be able to pause the large array for a few seconds, and then he can quickly pass through this layer of formation and enter inside.

Then Lin Mu began to search for the source of spiritual energy for these formations.

After three days of searching, Lin Mu finally found this source, and Lin Mu was very lucky, this source was not in this dense formation, but outside the formation.

This is a place where the aura is provided without knowing where the source is, and the aura here is so strong that it is almost outrageous.

The aura that was completely condensed into a liquid state flowed out at a hidden spiritual spring, providing the operation of the entire dense formation.

Looking at these completely liquid aura, Lin Mu was not polite, and directly extracted these completely liquefied spiritual liquids and put them into his ring.

These are the purest aura, but Lin Mu is now these resources, and now that Lin Mu has discovered it, Lin Mu will naturally not be polite.

"Ugh!"

Just when Lin Mu was smoking, the spiritual spring suddenly stopped.

"What's going on?" Lin Mu looked at the spiritual spring that was not gushing at all, and his heart was also strange. This spring seemed to know that it would extract spiritual energy again, and it was cut off directly.

However, since arriving at the Ten Thousand Beasts Secret Realm, Lin Mu has encountered too many strange things, so this spiritual spring suddenly stopped, and Lin Mu didn't care.

Moreover, at that time, there were already a lot of spiritual springs extracted from the forest trees, which was enough for the forest trees to cultivate for a year.

The spiritual spring was cut off, and Lin Mu no longer paid attention to the spiritual spring, but immediately shifted his attention to the large array.

The things in the big array are what Lin Mu wants the most.

Although the spiritual spring has been cut off, the aura here is still strong, and the formation can still extract the aura from the space to maintain the operation of the large array.

And the gap caused by the broken flow of the spiritual spring may only be a few seconds, so Lin Mu must hurry.

"It's now!"

"Whoosh!"

Lin Mu relied on his formation cultivation and keenly captured the moment when the formation was instant, and his body was like a lightning bolt, quickly passing through the layers of formations.

"Whew!"

As soon as Lin Mu passed through the formation, a strong medicinal fragrance came from the pavement.

This rich medicinal fragrance made the pores of Lin Mu's whole body open, and the whole person felt light.

Seeing the scene in front of him, Lin Mu was also a little stunned.

This is the place that is wrapped in the formation, and the area is not large, only a few square kilometers.

But these few square kilometers are densely planted with spiritual grass. And all the spirit grasses are already full of years.

The most inferior spirit grass here are all sixth-level spirit grasses. Of course, there are not many ninth-level spirit grasses here, most of them are seventh-level and eighth-level spirit grasses.

"It seems that what can be seen from the outside should be the scene here. Lin Mu looked at the scene in front of him and whispered to himself.

"Ten Thousand Empty Grass!"

Lin Mu suddenly saw a spirit grass suspended in mid-air, and exclaimed in surprise.

Lin Mu came here for it, and now that he finally saw it, Lin Mu was very happy.

"That's not right!"

Just as Lin Mu was about to stride forward to pick this Wankong grass, he suddenly stopped.

If that's what you see from the outside, then where did the first cultivator who came in go?

Lin Mu didn't believe that he had his own formation attainment, and he could pass through the obstacles of the layers of ninth-level spirit arrays and leave here.

Lin Mu stood in place, carefully releasing his divine sense to explore everything here.

But what makes the forest strange is that the spirit grass outside is protected by the formation, but the spirit grass here does not have a single formation, and every one of them is at your fingertips.

"Where's the essence of blood?"

Although the figure of the first cultivator to come in could not be seen here, and the spirit grass here was also not protected by the formation, Lin Mu still did not start immediately, but looked for the ball of essence blood that was marked by himself.

That ball of essence blood definitely entered here, but when it went there, Lin Mu couldn't sense it for a while.

It's not big here, and it doesn't have a suppressive effect on the consciousness.

So Lin Mu slowly closed his eyes, spread out his divine consciousness little by little, and carefully sensed the divine sense mark he had just made.

Half an hour later, Lin Mu suddenly opened his eyes, and finally felt that the ball of essence blood that had been marked by himself had gone there.

Lin Mu's face was solemn and he came to a place that was a hundred feet away from Wankong Grass, and then hit him with a heavy punch and blasted out directly.

"Boom!"

The violent aura, surging out, slammed into the space in front of him, and the space shattered directly like a mirror.

When the mirror shattered, Lin Mu was also shocked by the scene in front of him.
