Despite the best efforts of the tribal elders to maintain the inheritance of history and culture, there were still some ancient legends in this world that had been completely forgotten by the world. Just as people had forgotten the true meaning of the Dorasil pyramid complex, the other world above the zenith, and the real reason for the end of the Sun Dynasty, they had also forgotten everything about "the Terminal City of Xilador".

This was a myth that had been lost in history:

Buried beneath the Sun King's capital of Dorasil was a dark city shrouded in shadows, a mirror image of Dorasil in the underworld, known as "Xilador." From the moment it was built, this city in the shadows was hidden beneath layers of rock and steel, and enveloped by a thick protective shell, which was permeated with the blood and spirit of ancient sages, so that everything sleeping in the Terminal City of Xilador could sleep forever. In this forbidden place far from the human world, one could see huge houses without doors or windows everywhere. These giant stones were taken from the darkest and hottest depths of the earth, containing the powerful original power of the goddess. They were surrounded by the power of never-ending thunder, allowing the Terminal City to be in a state of constant charging. In the center of the city was a primordial cave called the "Throat of Toka."

Toka, the King of Giants, was a hunchbacked old man in local legends who carried the whole world on his back. He was ordered to take care of the goddess's garden, but he destroyed it because of his violent temperament. As punishment, the goddess ordered Toka to carry the newly created world on his back, and never to lie down and rest, nor to throw off the world. But Toka's violent nature was difficult to control. He only obeyed the goddess and agreed to carry the world because he feared her. This terrible giant king was always looking for a chance to get rid of the burden on his body. The wise goddess discovered this, so she had the ancient human sages build a city deep in the world, personally named it "Xilador," and drove seventy-seven god-nails made of thunder-stones into Xilador. The god-nails suppressed Toka's nerves, causing the violent giant king to fall into a long slumber, and the whole world ushered in stability.

Now Hao Ren and the others were standing in front of the "Terminal City of Xilador." The giant stone pillars that burst out with powerful electric light were the legendary "Seventy-Seven God-Nails," and the large cavity in the center of the city was the "Throat of Toka." The tentacles extending from the cave were the "nerves of the Giant King" mentioned in the myths. This was a real mythical city, but unfortunately no one knew about it now.

If Hao Ren and the others could hear that legend, they might be able to infer a lot of useful information. Unfortunately, this ancient story had been cut off thousands of years ago when a tribe encountered a plague. Now no one knew the myth of this underground city. The adventurers who broke into this place could only stare at this magnificent scene, guessing what role the electric stone pillars played in the whole system.

Hao Ren was not surprised by those tentacles. He even breathed a sigh of relief when he saw them. He had known for a long time that this world was built on the basis of the First Born, and seeing the traces of the First Born at this time only meant that things were progressing. He looked around and found a downward-sloping ramp at the edge of the platform, leading to the strange city.

He led the team towards the city, and Gazel gripped his war blade and followed behind. Before following, Bennie glanced at the tentacle-filled cave surrounded by lightning. The little saint was very scared. She swallowed hard, whispered a prayer, and hurried to keep up with Vivian: being by the latter's side made her feel more at ease.

The data terminal floated in the air, detecting the energy response of the giant stone pillars as it moved: "All the stones resonate with each other. This is a whole system. The entire city operates like a computer. I don't know how long the discharge reaction here has lasted. Its energy source seems to be those tentacles."

Hao Ren thought for a while: "The First Born provides energy to this city, and then the city uses electricity to stimulate those tentacles in turn?"

"It's not stimulation, it's singing a lullaby," A holographic projection appeared above the terminal, showing a three-dimensional model of the entire city. It could be seen that there were circles of blue waves around the large cavity in the center of the city. Those waves were the electric light released by the seventy-seven giant stone pillars, and as these blue lights surged, the electrical signals in the First Born's tentacles were suppressed to a very low level. "These things suppress the activity of the First Born."

"Just by these stones?" Hao Ren stared wide-eyed. He knew how large the First Born on this planet was—it was a truly adult individual. The three little tentacle monsters on Planet Holleta were nothing compared to it. "Did the ancients have such great skills?"

"So there must be some other force helping, and these tentacles initially seemed to be actively cooperating with being suppressed," the data terminal pointed to the huge stone pillars. "These things alone can't suppress the big guy underground."

The team came to the depths of the city, which was already very close to the circle of giant stone pillars where the electric light was the most intense. The crackling sound of electricity created an unsettling atmosphere, and the air was filled with the smell of ionized air. However, Hao Ren noticed that the current on those giant stone pillars was controlled: they only jumped and transmitted at a height of more than ten meters above the ground, so there seemed to be no need to worry about them suddenly striking down.

Nangong Wuyue transformed into a water snake, using mist to create a huge semicircular罩子 (zhàozi, cover) around everyone, so that even if lightning struck down, it could be conducted to the ground along the water cover. While maintaining this barrier, she looked up at the dark giant stone buildings in all directions with some worry: "I don't know why... I always feel like someone is staring at me."

"I have a bit of that feeling too," Hao Ren frowned, "It seems like there are gazes everywhere."

Lily immediately widened her eyes and looked around when she heard this. She also wanted to see if her psychic eyes could play a role, but obviously what was entrenched here was not an ordinary ghost. She glared around but didn't find anything, so she shook her tail: "I didn't see anything... but I don't like this place, there's static electricity everywhere. Look at what my tail has become."

Hao Ren took a look and found that Lily's tail had swelled to twice its size: it was caused by the static electricity in the air.

At this time, they passed a huge stone slab, which blocked the only way to the central pit. Ancient characters of this world were engraved on it. Nangong Sanba read it out: "Throat of Toka... what does that mean?"

"It should be related to the giant who carries the world," Gazel replied, "But the things about this city have been lost, and I haven't heard of it either."

Bennie stared wide-eyed at the bright electric arcs. Her curiosity and attention were attracted by the wonderful scenery of this city. And in the jumping of those electric arcs, she seemed to vaguely see some figures flying in the air. The little saint looked at these things with great interest, and her ears also moved slightly: "Goddess, they are singing oh~~"

Vivian was stunned: "Singing? Who is singing?"

Bennie pointed around: "It's everywhere, many people are singing to the cave in front."

Hao Ren did not let the little girl's words go casually, but he looked around and couldn't find where the "many people" Bennie was talking about were. He realized that this was a situation similar to the one in the ghost town of Domir: "I'm afraid they are spirits that only she can see."

"Pay attention to what they are singing and saying," Vivian instructed Bennie, "But don't follow them casually. Those should be ancient souls. They may not be malicious, but the place they are going to is definitely a place you can't go to."

Bennie nodded as if she understood: "Oh."

They came to the side of the huge pit called "Throat of Toka." Here, the ground was almost completely covered by the First Born's tentacles. Countless huge black roots stretched out from the ground and reached towards the surrounding electric stone pillars, and faint electric sparks wandered on the roots. Hao Ren carefully came to the edge of the pit, poked his head down, and could only see a bottomless chaotic darkness, and a little vague red light in the darkness: that was either lava or a large organ of the First Born.

The data terminal detected it and found that the tentacles here retained a high degree of activity, but it still did not detect the First Born's clear nerve activity: everything was suppressed by the surrounding electric stone pillars. These tentacles were sleeping as if they were dead.

Hao Ren, as usual, threw a few probes down into the cave, and then waited quietly for the probes to transmit the situation below.

After the initial data was transmitted back, the data terminal suddenly let out a whistle: "Whew—partner, it seems that your initial question has an answer: the energy source of this planet's ecosystem has been clarified."

Hao Ren was immediately very interested: "Where did it come from?"

"The First Born is devouring the planet itself."
