Edway's assimilation made Du Mu more and more confident in passing the assessment.

The next night, he went straight to the island.

Looking down from the sky, the island has been devastated and devastated, and the green forests that used to be everywhere are now gone, and more than seventy percent of the earth and rocky ground has been hollowed out, revealing the Liuling formation underground.

In the middle of the island, the Liuling Formation has an area of about 1,000 square meters that is dyed grayish-white.

"I still haven't found the reason why these guys are destroying the terrain. Du Mu sighed lightly.

After this period of hunting, there were only four or five thousand furious people left all over the island, but even after killing so many furious and eroding people, he still couldn't investigate the reason why these monsters were so keen to destroy the island and 'infect' the Liuling formation.

Gathering his thoughts, Du Mu fell to the ground and summoned the gray dream.

The thick gray mist quickly spread, and Edway, Xiao Jiu, Carol, and Hilson walked out of it one after another.

After two months of absorbing Gray Dream, Xiao Jiu, Carol and Hilson have all broken through the 5,000 mark in combat power and advanced to the seven-star level, among which Carol has the highest strength, with a combat power of 5,839.

Since the strength of the four gray servants far surpassed the furious ones, Du Mu simply let the four of them scatter and hunt the furious ones all over the island.

With the help of the gray servants, the efficiency of the hunt really improved a lot, and by the evening of the fourth day, Du Mu had already emptied most of the furious people on most of the island, leaving only four or five hundred meters near the central fog ball, and there were still more than a hundred furious ones.

Under the combined attack of Du Mu and the four gray servants, the remaining berserkers quickly followed in the footsteps of their companions.

Four or five thousand furious people brought Du Mu a total of thousands of nightmare energy gains.

"It's a pity that it's still not enough, at least it takes about fifteen hundred nightmare energy to light up enough stars to break through the three dominant attributes again. Du Mu sighed secretly, "Take your time, this matter is not in a hurry." ”

"The fog seems to have lightened a bit. Edwin looked around and said suddenly.

When Du Mu heard this, he looked up, and sure enough, he found that the fog around him was fading at a speed visible to the naked eye.

At the same time, the fog ball suspended in mid-air was gradually shrinking.

This scene surprised Du Mu, the fog ball in the ancient grassland of the mountain was wiped out by the nightmare creatures guarding it, but it took several days to condense into a nightmare nest, and the fog ball in front of him shrank much faster than that.

"Maybe it's because the fog hasn't spread?" Du Mu showed a thoughtful look, the fog that escaped from this fog ball had no signs of spreading, but remained within a radius of thirty or forty meters from the fog ball, perseveringly 'infecting' the Liuling formation below.

Perhaps because there was no need to retract the fog, the fog ball contracted much faster.

After waiting patiently in place for almost two hours, under Du Mu's gaze, the huge fog ball finally shrank into a palm-sized quaint stone, which was a nightmare lair.

Although the fog ball on the island was much larger than that of the mountain ancient grassland, the nightmare nest that was condensed in the end looked the same, Du Mu looked at it for a while, and quickly lost interest and threw it into the dimensional house.

He doesn't plan to set up a new Nightmare Lair template until he obtains a more powerful Navy figure, and one Nightmare Lair that can make a six-star Navy is enough, no matter how much it is.

"My lord, that ground seems a little weird!" Edway's voice pulled Du Mu back from his contemplation.

Looking in the direction that Edwei was pointing, Du Mu was surprised to see the Liuling Formation that had been dyed gray, and the gray marks on it seemed to have decreased a lot.

After taking a closer look, Du Mu immediately found that this was not an illusion, the edge of the gray and white traces was indeed rapidly retracting, revealing the original six-rhombic pattern.

"Does this land still have the ability to heal itself?"

Du Mu originally wanted to leave, but when he saw this scene, he was suddenly very curious, so he simply stayed in place, watching the gray and white traces continue to shrink and recover, and after half an hour, the entire Liuling formation has no longer seen a trace of gray and white, and the dense Liuling lines exude a dazzling luster like metal in the sun.

At the moment when the last trace of gray disappeared, Du Mu clearly felt that the ground under his feet suddenly trembled.

"Earthquake?"

Du Mu's heart moved, and the four Edwei who were standing quietly on the side instantly turned into a gray dream and returned to his body, while he kicked under his feet and jumped into the air with moon steps.

Looking down from the sky, the entire island trembled as if an earthquake had occurred.

Under the violent tremor, the intact ground and rock walls that had been protected from the poisonous hands of the furious suddenly appeared large cracks, and then shattered, and the rock walls collapsed, and the ground cracked, revealing the six-rhombus lines underneath.

In a matter of moments, the entire terrain of the island was devastated, and there was nothing left intact.

Du Mu stayed in the air, staring at the terrifying scene in front of him in a daze, his eyes swept from the six-ling patterns and gravel all over the ground, a look of shock gradually appeared on his face, and an astonishing thought flashed in his mind.

He stepped on his feet, climbed a little higher, and in a short time came to a position where he could see the whole island, and looked down intently.

When he saw the panoramic view of the island, his eyes widened.

Compared to a moment ago, the height of the island had risen significantly, revealing the part that was originally hidden under the surface of the sea, and from Du Mu's position, he could not see the details clearly, but he was soon shocked to see that from the position on the left and right sides of the island, four dark green things suddenly slowly protruded.

After staring at it for a long time, Du Mu gradually realized that it seemed to be four turtle legs.

Before he could figure out why there was a turtle foot, a huge head slowly poked out in front of the island, setting off a raging wave.

Du Mu suddenly gasped.

At this time, he still didn't understand that the island in front of him was not an island at all, but the body of a huge monster.

And judging from the scene in front of you, this monster seems to be a kind of turtle?

"No wonder those furious people dig the ground all day, that's why!"

Du Mu finally connected everything together, those strata with six-lingling patterns turned out to be the turtle shell of this turtle monster, thinking that it should be a turtle giant beast sleeping in the sea, under the accumulation of wind and sand, the turtle shell gradually condensed a layer of rocks, and there were birds and beasts through the tree species, over the years, gradually developed into an island.

One day, it was suddenly invaded by Nightmare Isolation and took over the island on its shell.

The reason why the berserkers are destroying the terrain is to dig up the tortoise shells underground, so that the mist can touch the tortoise shells and gradually transform.
