The entrance that was knocked open was a meter or two in diameter, enough for the poplars to pass through.

But the wolf king is not among them.

"Don't worry, your benefits are indispensable."

Poplar spoke comfortingly.

The wolf king's expression was depressed, and his depressed expression made Liu Yuting's maternal brilliance shine.

"Stay good, we'll be back soon."

Liu Yuting patted the wolf king's bowed head, as casual and natural as he instructed his puppy before leaving home.

It's really a "wolf concubine", Poplar is jealous in his heart.

A few minutes later, everyone was ready, just in case, it was Poplar who led the way.

But just as Poplar was about to step over the narrow portal, the foot that had just stretched out suddenly stopped in mid-air, and then the old disease recurred, and the dantian trembled again.

Everyone looked at Bai Yang's strange posture and was a little confused, but Liu Yuting reacted and found that something was wrong.

But fortunately, the symptoms this time were much milder than before, and it only took about ten seconds for Poplar to recover and breathe a sigh of relief.

"How?"

Liu Yuting stepped forward to ask.

"It's okay, I feel like this is the crux of my condition."

Poplar's eyes were deep, and he looked at the seemingly endless passage inside the cave entrance.

Ever since he entered the area, this feeling had never disappeared, so much so that Poplar had become accustomed to it before.

Now that the symptoms have recurred, his feeling in the dark has immediately deepened several times.

It's like something in the subconscious, which he has brought to the surface, and it is very clear.

"Let's go in and see, and if there's anything wrong, go back."

Poplar's right foot landed and he officially stepped into the area on the other side of the hole.

The group behind followed, continuing to move unhurriedly down the diagonal passage.

As the descent gets longer, the terrain gets steeper.

Halfway through they made a turn, and according to Poplar's assumption, the direction they were now heading should be the direction of the primeval forest.

Yes, they circled back into the primeval forest, but now they should be directly below it.

The height of the passage down is also two or three meters, so it will not make everyone feel particularly depressed.

Even more surprising are the occasional marks on the rock face, which make Poplar think that this is most likely not a natural cave.

Poplar silently calculated in his mind that so far, the distance they had traveled from the corner in a straight line was about 5 kilometers, and the vertical distance was also close to 3 kilometers, so that they were now 3,000 meters underground.

The speed of the crowd was very fast, and although they slowed down due to caution along the way, it only took ten minutes to travel a few kilometers.

When Poplar raised his hand to signal to rest in place, they realized the depth and position they were in, and they were surprised for a moment.

"It's unusual." The Ninth Master sighed, "Such a deep cave is rare in the world, right?" ”

"It won't go straight to the eighteenth-story underworld, will it?" Wei Dabao is not a big deal.

"That's fine, I really want to see the true face of the Ten Palaces Yama." Poplar quipped.

"Enough of you." Liu Yuting rolled her eyes.

Several people stopped ridiculing, and Poplar finally said in the right way:

"If there is any sudden accident, I will be the queen of the palace, and you will take someone to go first."

"You know how to be a hero." Liu Yuting complained a little.

"Anyway, I've got a hero, isn't it." Poplar smiled optimistically.

"At our current location, we should be almost in the middle of the primeval forest, and I feel like that's where we're going."

"Get everyone ready and ready to respond to the situation."

Poplar commanded, the feeling of uneasiness still lingering in his heart.

But even if he was uneasy, it still couldn't stop him from wanting to explore.

Keep going, nothing to say all the way.

After a few minutes, Poplar finally saw a faint light appear not far from the diagonal bottom, and his mood suddenly became a little excited.

Others noticed the sign soon after, and there was a small commotion in the crowd.

The distance of hundreds of meters was a moment, and Poplar waved his hand to stop the team's progress, and went to the exit to find out.

Stepping out of the hole, Poplar looked up and looked at the moment his expression became dull, and he looked at the breathtaking scene ahead in disbelief.

I saw that this side of the space was extremely empty and huge, and in the very center of the space, there was a semicircular light curtain about a kilometer in diameter that was turned upside down.

The light curtain is milky white, and the flow of light and shadow illuminates the surrounding dome-like space transparently and brightly, like half a small sun, expelling every inch of darkness in this area.

The people behind him were still hidden in the dark, only to see the scene of the immobile back of the poplar stunned outside the cave entrance.

The Ninth Master first couldn't hold back, rushed to the front and squeezed out the narrow dark passage, and then was stunned on the spot like a fool.

"What's the situation?"

Everyone couldn't help but be curious, and took turns to go out of the cave to see the situation outside.

Then the scene repeated itself, and dozens of people lined up in the last line looking at the scene in front of them in a daze.

"What a miracle!" A few minutes later, the Ninth Master sighed and pulled everyone back to reality.

Poplar took a deep breath, calmed down for a moment, and then began to carefully observe the surrounding scene.

Except for the light curtain in the center, there is nothing else in this space.

Under the light curtain, the space with a diameter of two kilometers and a height of several hundred meters gave him an unobstructed view.

Then all the answers are in the depths of the light curtain.

"Let's take a look, be on guard at all times."

Poplar gave the order.

The group slowly moved towards the light curtain.

The white light shone on everyone's faces like a warm sun, and there was a faint warmth, which made them quite enjoyable and comfortable.

But Poplar always had a heart, and that vague sense of uneasiness became more and more obvious as he got closer to the light curtain.

After halfway through, Poplar finally didn't dare to continue.

He wasn't afraid of what would happen to him, he was worried about his companions behind him.

"You wait here, I'll go up and see for myself."

Liu Yuting and the others still wanted to speak, but they were stopped by Bai Yang's resolute eyes.

"It's not easy here, it's enough for me to take risks alone, if the situation doesn't work for me, I'll run faster than you."

What Poplar said was true, so they had to stay put.

Taking a deep breath, Poplar reorganized his pace and walked slowly towards the light curtain step by step.

Two hundred meters, one hundred and fifty meters, one hundred meters......

Poplar was a little nervous, because he didn't know what was going to happen in the next moment.

It wasn't until Poplar crossed the last hundred meters and came to the close distance of the light curtain that he breathed a sigh of relief.

He tried to check the situation with his clairvoyant eye, only to find that when the Heavenly Eye Nianbo touched the light curtain, it was all bounced back.

But he is not in a hurry, and the next step will be the most crucial, which is to try to enter this light curtain.

Poplar slowly stretched out his right hand and stretched out his five fingers to penetrate the light curtain, but when he touched this barrier-like light curtain, he found that it was difficult to enter, and there seemed to be a lot of force repelling Poplar.

Just as he was about to exert more force and try again, he suddenly heard a sound like a mechanical rotation from the depths of the light curtain, and the clicking sound was incessant.

Then everyone felt that the ground trembled with great regularity, and at the same time, the sound of a heavy object hitting the ground rumbled from inside the light curtain.

Bai Yang's sense of uneasiness reached the extreme in an instant, and he immediately withdrew his right hand and retreated dozens of meters, then turned around and shouted at the people behind him:

"Retreat, go back!"

As soon as the words fell, there was a sudden emotionless sonorous voice full of metallic texture behind him:

"If an outsider is detected, if he has no identity, he will not be killed!"

Then a fan-shaped red barrier shot from behind him, quickly passing the dozens of people who were starting to run back and forth, but everyone did not feel any discomfort.

"After identification, there is no identity, kill!"

"I'll kill your uncle!"

Poplar couldn't listen to it, and suddenly became angry, stopped running, and turned to face the location where the voice came.

I saw that outside the light curtain at this time, there was a burly body four or five meters high standing upright.

The body is humanoid, but it is made of some kind of metal construction throughout its body.

"Holy, Autobots? Or a robot? ”

Poplar was shocked.
