The humanoid metal object is tightly structured, and the metallic texture on its body is full of impact, and it doesn't look like it's simply put together from various parts.

The silver-gray metal appearance, shining in the light curtain, coupled with its huge size and perfect body with a sense of strength, made Poplar goosebumps stand all over his body.

"Topol, come back!"

Liu Yuting shouted in the distance.

The appearance of the metal giant caught everyone off guard, and at the same time, there was a sense of extreme danger in their hearts.

This feeling is much stronger than the threat of the wolf king, and if they continue to stay here, everyone will surely die.

The eye of perspective swept over, and Poplar saw the purple crystals that glittered at the moment at the heart of the metal giant.

The crystal didn't look big, only the size of a fist, but the energy contained inside it seemed to be much larger than the one-meter-diameter amethyst of the Wolf King.

In addition to the purple crystals, Poplar also saw that there were energy filaments in it, radiating from the amethyst, filling the giant's huge body, and each filament had countless smaller branches, extending under every inch of the giant's metal skin, providing it with a steady stream of purple energy.

This is a perfect energy network, just like the neural network that the human body has.

"Really, really!"

Indulging in the visual shock brought to him by the metal giant, Poplar has completely forgotten to respond to Liu Yuting's urgent call.

"The primary goal, the initial strength of the cultivator, kill!"

The metal giant's cold voice came, and his emotionless gaze fell on the poplar, who was still in shock.

But the next moment, Poplar actually moved.

Instead of running in reverse, he began to move quickly around the giant.

Not only did he want to delay the others, but he also wanted to fight the giant.

He had also guessed the origin of this giant and the white light curtain, ancient human civilization? Or is it some other extraterrestrial civilization?

But it can also be known by the method of elimination, which is definitely not a product that can be produced by modern human civilization.

There are only two possibilities left, and he naturally prefers the former.

As the current guardian of the earth's civilization, the ancestor can rely on the heavenly machine to grasp the dynamics on the earth at all times, so how can he tolerate the things of extraterrestrial civilizations to exist in the interior of the earth?

So the answer is already relatively obvious, this is a game under the old ancestor, maybe it's just one of them.

This is also the main reason why Poplar dares to challenge this giant, he has not reached the point where he is not afraid of death.

"Don't worry, you can't die!"

Poplar shouted at the group in the distance as he ran.

The others were suspicious and could only stand and sway back and forth at the entrance where they entered.

"I'll trust you one last time." Liu Yuting gritted her teeth and complained a little in her heart.

In her opinion, Poplar's behavior is a typical hero.

"I know you're strong, but everything has to have a degree, right?"

Liu Yuting thought dissatisfiedly in her heart.

"Sky Eye, Amplification!"

Poplar drank violently in his heart, and he was directly in the peak state after opening the increase of the Heavenly Eye.

"Sky Eye, Phantom Energy!"

The thought wave was silently unleashed, bombarding the giant's brain, trying to influence the giant's judgment.

But it didn't work.

Poplar was surprised to realize that this giant was not a living thing, and there were no brains and so-called brain waves.

"I can only resist it."

Poplar smiled bitterly and took the lead in launching a tentative attack on the giant.

"Deadly Knife!"

"Bell!"

Poplar struck with all his might, slashing easily at the giant's thigh, sending out a deafening metal thump.

But the giant didn't move, and the poplar's attack didn't even leave a trace on the metal surface.

"What am I special, how can Lao Tzu fight this defense?"

Poplar was sure that even if it was as hard as steel, it would have to be split in half under his full force.

One side is mortal and the other is invulnerable, which is a completely unfair challenge.

But who let Poplar go straight to it like a reckless man?

The next step is to withstand the terrifying counterattack of the giants, right?

"What a mistake."

With a sigh, Poplar put away the useless Tang knife and began to greet the metal giant who was about to start attacking.

The earth roared and trembled, and the giant strode forward, and in a few steps he stepped in front of the poplar, and a huge fist like a giant hammer struck at the poplar.

Poplar dodged and retreated, dodging a blow.

The huge fist wind howled, and it attacked the aspen continuously at an extremely fast frequency.

Despite its huge size, the giant's speed was no slower than that of Aspen.

Poplar could only dodge back and forth, moving left and right, and did not dare to collide with the giant head-on.

"Bell!" With a bang, Poplar found a rare opportunity, jumped up and slammed his fist on the door of the giant's face.

But the shock force from his fist made him fly straight upside down, and at the same time, his right hand trembled, obviously this blow made him feel painful.

The metal giant quickly counterattacked, and in the blink of an eye, it was in front of Poplar's eyes.

"Ancestor, do you want to continue?"

Poplar shouted in his heart, and at the same time had already given up resistance, standing still in place.

He's going to take a gamble, and he can't beat it anyway.

"That's it."

A familiar voice appeared in Poplar's mind, and then the giant's fist suddenly paused in mid-air, and then retracted the attack and stood still.

At the same time, among the three Tabi stars who had long been hidden in the shadows, Ada was the first to sense.

"Guardians?"

Originally, the three of them were ready to help Poplar, but this could only expose their existence.

However, the guardian of the human race on Earth was one step ahead of them, and it now seems that the current situation may be the work of this guardian.

"You kid, you can still see through my layout."

Old Ancestor was a little surprised.

"Old Ancestor, you underestimate me too much, don't you?" Poplar chuckled.

"Ancestor, what are you going to do here?"

Aspen naturally refers to the so-called layout.

"It's time to make it public." The ancestor said lightly, with a hint of helplessness.

"So fast?" Poplar was surprised.

"Time is pressing, it's useless to talk too much, do what I say is right."

"And what am I going to do?"

"Get in on this, we have to speed things up."

"And my other companions?"

"Those who see have a share, but what they can get depends on their respective talents and opportunities."

"Alright, that's all for today, you guys go in."

The ancestor's appearance this time was unprecedentedly brief and urgent, as if there were other important things to do.

As the voice of the ancestor fell, the light curtain not far away began to fade slowly, gradually revealing the scene inside.

When they saw the specific situation, everyone present gasped.

After the light curtain disappeared, there were hundreds of metal giants standing in it, but they were not in an active state.

In addition, there are several high platforms that resemble small pyramids, with some strange equipment on them, which look full of technology.

"The Altar of Truth?"

Ida looked at the high platforms and said with some surprise.

"Looks like the Guardians are going to make a big move." Cynthia was stunned, she didn't expect to see these things here, she had only heard of them before, and she hadn't really seen them.

"The altar? Is this the place where these hillbillies are sacrificed? ”

"Don't talk if you don't have much knowledge." Cynthia gave him a blank look.

"The altar of truth is built by human civilization to preserve the flame of its civilization, and to put it bluntly, it is an intelligent memory, or artificial intelligence, that stores all the scientific and technological achievements and cultivation experience in the history of human civilization, and we will continue to fill and accumulate it."

"When we came to Taby, it was this that restored the glory of the past."

"The reason why it is called the Altar of Truth is because our ancestors believed that with the continuous evolution of civilization, it will eventually reach an evolutionary extreme, and maybe that is when we will truly discover the truth of this universe."

"It's a kind of sustenance, but also a kind of longing."

"As for the altar, we get the benefits from it, and then feed back new fruits, don't you think this way is very similar to sacrifice?"

After listening to Ada's explanation, the other two had the same expressions on their faces.

At this time, Bai Yang and the others have begun to approach the area in the center of the space, and what awaits them may be a transformation in the true sense.
