And the last one, I will never give up!

————————

Lin Mu still believed in his instincts very much, and sensing this dangerous feeling, Lin Mu immediately withdrew his hand and left the growth range of the seventh-level spirit grass at the same time.

But it's strange to say, as soon as Lin Mu left the growth range of the seventh-level spirit grass, the sense of danger that seemed to be absent immediately disappeared.

Such a discovery made Lin Mu a lot more cautious about this seventh-level spirit grass.

This is a Divine Transformation Grass, which is a relatively precious one among the seventh-level spirit grasses. You can refine the Divine Pill, which is a pill that helps the monks of the Divine Realm to break through the small level.

Lin Mu also used the Transformation Divine Pill back then, and at the same time, he also personally refined the Transformation Grass, but Lin Mu didn't think that there was any danger in this Transformation Divine Grass back then.

The forest surrounded the Divine Grass, looked at it for a long time, and did not find anything wrong with this Divine Grass.

Since it is certain that there is no problem with the Transformation Divine Grass, the problem must be in the place where the Transformation Divine Grass grows.

Lin Mu carefully observed the place where the Avatar Grass grew, and finally Lin Mu found something.

It turned out that this Divine Transformation Grass was shrouded in a layer of phantom array, and this phantom array was quite exquisitely arranged. If you don't look closely, you won't be able to spot it.

With such a formation technique, even Lin Mu is not as good as himself.

This small phantom array itself does not possess any attack ability, but it can affect people's minds and make people have the illusion of thirst for killing, thinking that this is the real reason why the two monks of the Silent Annihilation Realm finally died together.

Lin Mu pulled out the shadowless knife and slashed it down, directly smashing the phantom array that shrouded the Divine Grass.

Without the phantom array, there would naturally be no danger, Lin Mu picked up the Divine Grass, looked at it and didn't find anything special, and directly threw the Divine Grass into the ring.

Putting away the Divine Grass, Lin Mu stood in place and did not leave immediately.

The discovery here made Lin Mu feel that this secret realm of ten thousand beasts was becoming more and more difficult.

A Divine Transformation Grass is protected by such a subtle formation, and it is conceivable that the other elixirs in it, which are much more precious than the Transformation Divine Grass, will have what kind of formation protection it will have.

And Lin Mu was still thinking about a question, that is, how did this Ten Thousand Beasts Secret Realm come about.

Looking at the number of years of elixir growth here, it is obvious that this Ten Thousand Beasts Secret Realm has existed for a long time.

But after existing for so long, there was no movement at all before, as if this secret realm of ten thousand beasts fell from the sky, and suddenly appeared, without any warning at all.

Moreover, after Lin Mu's observation just now, although the formation outside the secret of ten thousand beasts is a natural formation, the formation inside it is completely man-made.

But why did that person arrange so many formations in the Ten Thousand Beasts Secret Realm, and what was he talking about? Not to mention such a large amount of arrangement of formations, such a consumption was an astronomical amount? In the cultivation realm, he had that great power and such ability?

These incomprehensible things all made Lin Mu feel deeply uneasy.

"Huh!"

Just when Lin Mu was thinking about the secret of this Ten Thousand Beasts Secret Realm, Lin Mu discovered something strange.

Lin Mu looked down at the two cultivators who had just died, the corpses of the first layer of Silence were rapidly drying up, and all the essence and blood in their bodies were rapidly being absorbed by the ground beneath them.

"Could it be that this entire Ten Thousand Beasts Secret Realm is alive?" Lin Mu was also taken aback when he saw the land under his feet absorbing essence blood.

If this entire Ten Thousand Beasts Secret Realm was alive, then this would be a bit too sensational.

A living creature with a volume of tens of thousands of miles, this is simply unimaginable.

"Drink!"

Lin Mu didn't believe that time could have such a huge living thing, so he also carried the Shadowless Knife and slashed down with a heavy knife, splitting the ground under the two of them.

Lin Mu's knife was extremely deep, but the effect was also very obvious, and as soon as the knife went down, Lin Mu really saw the essence blood lost by the two masters of the Silent Annihilation Realm just now.

However, these essence blood only appeared for a moment, and then seeped into the land again, and instantly went into the distance.

Such a discovery made Lin Mu's expression shocked.

Lin Mu slashed out again and saw those essence blood again, but this time Lin Mu's divine sense attacked decisively and marked his own divine sense mark directly on the essence blood.

Then Lin Mu flew up directly, following his divine sense mark, and quickly flew forward.

The speed of essence blood is very fast, and it has almost escaped the range of Lin Mu's divine sense several times, but fortunately, since Lin Mu has mastered teleportation, even without teleportation, his flight speed is much faster than before.

Lin Mu followed this wisp of essence blood and quickly advanced into the depths.

Lin Mu followed this wisp of essence blood and flew for three days and three nights, and Lin Mu didn't know where he was at this time.

"Gone?"

Just when Lin Mu felt the speed of the essence blood slowing down, the next moment the essence blood suddenly disappeared.

"No! there must be a hidden formation to shield the divine consciousness here!" Lin Mu said as he looked ahead at the huge basin that was empty.

Lin Mu didn't believe that his divine sense mark would disappear for such a reason.

Looking at the void in front of him, Lin Mu pulled out the Shadowless Knife, and then used all his strength to slash down with a heavy sword.

"Whoosh!"

The cold blade, with a rolling aura, surged forward.

"Boom!"

The blade slammed into an invisible protective cover, and then the protective shield wriggled for a while, and then all the blades were consumed.

"Sure enough, there is a formation!"

This made Lin Mu smile slightly.

Now that we have found the location of the formation, the next step is how to break the formation.

Lin Mu first poked out a wisp of divine consciousness to contact the formation in front of him.

As soon as his divine consciousness and the formation came into contact, Lin Mu felt a tearing pain in his divine sense.

"There's even a hidden formation inside that can attack the divine sense!" Lin Mu hurriedly pulled out his divine sense, and his face turned pale for a while.

However, the more complicated this formation is, the more sure Lin Mu is that there must be something good here.

Lin Mu took out his communication jade slip and tried to call Zhou Songliang and Mo Fei, but Lin Mu was surprised to find that when he arrived here, his communication jade slip seemed to be cut off.

Putting away the communication jade slip, Lin Mu finally focused his attention on the formation in front of him.

Lin Mu was not a formation master, and when he was in the immortal realm, he was barely able to arrange a second-level immortal array.

But it doesn't matter if you are not a formation master, Lin Mu now has the strange book "Array", and Lin Mu doesn't believe that he can still break the formation in front of him with "Array".

Lin Mu didn't try to study "Array" before, because Lin Mu was worried that he would not be able to chew too much.

But now that Lin Mu has time, he can also officially start and hone his formation.

After all, Lin Mu used to be an immortal, and his understanding and foundation of the formation were still very strong.

Therefore, although the explanation of the strange book "Array" is very mysterious, it is not so difficult for Lin Mu to understand.

Before the forest was in the big array, one was a month's time.

It took Lin Mu a full month to finish half of "Array".

Although he had only seen half of it, Lin Mu felt that his formation cultivation was rising in a straight line.

My understanding of the formation in the past month is almost as much as the sum of my previous understanding of the formation.

The latter half is not that Lin Mu doesn't want to see it, but it's too complicated and complicated.

If Lin Mu still wants to continue to watch, I'm afraid there won't be ten years to finish reading it at all, but there is obviously no time in front of him to let Lin Mu look at these things.

Standing in front of the large array, Lin Mu took a deep breath and carefully poked out his divine sense again.

Lin Mu believed that if he could resume his cultivation at this time, he would definitely be directly promoted to a fourth-level immortal array master.

With his fourth-level immortal array master's formation attainments, the array in front of him should no longer be a problem.

However, when Lin Mu's divine sense penetrated again, he realized how naïve his thoughts were!
