The three of them walked to the depths of the cave, and they didn't know how the old scientist led the way, Lu Lie only felt a flower in front of him, and on the mountain wall where the mountains and rivers were exhausted and there was no way out, there was a village again.

The three of them walked into a narrow crack that only allowed one person to pass through, and after the crack, it turned out to be a vast world.

"That's ......"

Lu Lie was stunned by the scene in front of him.

A huge black tree, far greater than the Dryad's Grandmother, stood in the middle of this wide cave. It is like the pillar that supports heaven and earth in mythology, supporting the mountaintop and the earth in this giant tree world. The old scientist and the others slowly walked to its feet, like three ants walking to the feet of giants.

Trees, and trees again...... Lu Lie felt that in his life, he was in conflict with the tree's life. As soon as he saw the tree, he almost threw it up!

The only thing that made Lu Lie thankful was that the black giant tree was undoubtedly a dead thing. I won't be the same as the one outside the valley again, and a human face will emerge from the trees again.

"Zizi Zi ......"

The earth began to tremble slightly with the painful crash of metal between them, and something was rapidly approaching it. Lu Lie looked around nervously, only to find that the old scientist and Li Yuan still looked calm.

"Boom!"

There was a thud in the center of the black tree, as if something from the ground was stuck in the tree. Immediately after, the bark of the giant tree was strangely torn open, as if a door had been torn open by a pair of invisible giant hands, revealing a square metal lattice inside, which could hold four to eight people. The walls, painted with an unknown material, emitted an ominous white light.

Lu Lie was completely confused by the scene in front of him: "This is ...... What is this thing?"

The old scientist seemed to be very satisfied with Lu Lie's shocked look, touched his white beard, and was the first to walk into the metal lattice. Then he turned his head and beckoned to Lu Lie and Li Yuan, who were still outside, "Come in quickly." We're going to ride this thing all the way to the top of this giant tree!"

Li Yuan showed a sly smile on his face and introduced to Lu Lie: "This metal box that can sit on people is called 'elevator'. Once we sat inside, it sped all the way up until it brought us to the top of the giant tree...... Not only is the speed of this elevator fast, but it is also able to protect us from many dangers in this black tree. Otherwise, it would be stupid to climb up the tree wall outside, tens of thousands of meters above, and I don't know what other disasters will happen, so that the ghost can climb to the top of the tree alive. ”

The two of them had already walked into the metal lattice, waiting for the "elevator" to start, leaving only Lu Lie alone, still looking at the strange device in disbelief.

"What?" the old scientist beckoned to him impatiently, "Come on in." Still stunned. ”

Lu Lie muttered in his heart: Could it be that this metal lattice can really take him to the top of the tree like this? If so, wouldn't he be able to leave a lot of strength in vain?

If such a device really exists in this world, you can easily reach the top of a tree by pressing a few buttons and waiting for a while. In comparison, in this giant tree world for hundreds of thousands of years, countless strange people and masters who want to climb to the top of the tree are not as stupid as fools.

Lu Lie has been bumpy and displaced since he was a child, and he doesn't know how much more he has suffered than others. Therefore, he always has an extra eye for this kind of pie that falls from the sky.

No matter how Li Yuan and the old scientist in the metal lattice called, he just stood still. Stunned, he looked at the strange black giant tree and the silver lattice inside the giant tree, trying to find some flaws in it.

"Lu Lie ......"

At this time, his familiar faint call sounded softly in his ears again.

Lu Lie was stunned for a moment, this time, the woman's resentful call was too real, and he was very sure that it was not an auditory hallucination at all. It's just that in this huge cave, there is nothing else but the three of them, and what is it that keeps calling in his ear?

Lu Lie's face changed, he had always disbelieved in ghosts and gods, and disrespected heaven and earth. However, is there really a ghost in this dark world, which has quietly entangled his fate?

"Lu Lie, what are you doing, you haven't come up yet?"

Li Yuan also found that something was wrong. Lu Lie, who was originally standing outside, had no intention of coming in at all, on the contrary, his face changed drastically, as if he had seen something that was absolutely impossible. Li Yuan turned his head to see what was behind him that made Lu Lie lose his color, but found that there was nothing in the metal lattice except for the four iron walls.

"Lu Lie ......"

"Lu Lie ......"

"Lu Lie ......"

The call became more and more urgent, and it became more and more resentful.

At this moment, Lu Lie forced himself to calm down. What are you afraid of, it's a big deal that people die and birds are facing the sky. I don't know how many times I have experienced the desperate situation of life and death along the way, if I really want to talk about it, he should have died more than a dozen times, and it is not bad this time.

Even the source of this invisible sound wants to harm himself, and he Lu Lie must also find out where this strange sound source came from before he dies? You must not lose your life here for no reason, even if a trace of a wandering spirit swims to the underworld, you will be a fool for some reason, isn't it wronged?

Thinking of this, Lu Lei calmed down, held his breath at the moment, and secretly observed around. No matter how the old scientist and Li Yuan in the metal lattice urged, he no longer paid attention to them.

Could it be...... The ghost of the dead tree demon grandma is coming for revenge again?

Lu Lie thought of this, and immediately overturned his ridiculous idea. Let's not mention that the female voice that lingers in my ears is completely different from the rough voice of the dryad grandma. Besides, the tree demon grandmother voluntarily gave her the natal orb to herself, and then turned it into a ruin. She clearly committed suicide knowing that she would never be able to leave the giant tree no matter what, and she missed her family. How can this account be credited to yourself?

Speaking of Dryad Grandma...... Could it be that it was the natal bead she gave herself that caused the trouble?

This tree demon grandmother has lived in the giant tree for many years, and I don't know how many adventurers she has killed. When she was still alive, ghosts were also afraid of the wicked, and those unjust souls naturally didn't dare to have any opinions. As soon as she dies, could it be that these unjust souls will come to trouble themselves with the Grandma Tree Demon's Natal Divine Bead? Or, what kind of alternative life form is this Natal Divine Bead itself?
