Inside this magnificent hall, the towering dome is hidden in the deep darkness, dotted with dense, flickering bright spots of various colors.

  With just a quick glance, Jia Lan recognized that this was a large-scale star map. He had seen a similar star map on the top observatory of his mentor's wizard tower.

  However, compared with the "Eberron Macro Galaxy Map" inlaid with countless gems here, that star map seems much inferior.

  Despite this, compared with the "Independent Crystal Wall System Micro Plane Map" owned by Jia Lan's mentor, this "macro galaxy map" still seems insignificant.

  Neither the "macro star map" nor the "micro star map" is within Jia Lan's current realm.

  He just glanced at it and felt a strong dizziness, almost unable to stand steadily.

  He closed his eyes tightly and tried his best to endure the dizziness. After a long rest, he gradually returned to normal. He was still frightened and did not dare to look up at the dome again.

  This also made him understand why his mentor never allowed him to go up to the observatory.

  With his "double soul", he has a mental strength comparable to that of a seventh-level great wizard.

  Even after waking up from the ice, his soul and spiritual world experienced some unknown improvements without his knowledge.

  Theoretically, with his conditions, he is already a leader among stargazers.

  However, he only took a quick glance at this "Eberron Macro Galaxy Map" and barely identified the thirteen "plane nebulae" and their corresponding thirteen "sub-satellite clusters" shrouded outside the Eberron world, and almost fainted.

  It is hard to imagine what consequences he would face if he studied this star map in depth.

  Spiritual exhaustion?

  Soul damage?

  Even the soul was pulled out of the body?

  This is just a "macro star map".

  Recalling his experience of trying to sneak into the mentor's observatory but giving up because he couldn't solve the restrictions set by the mentor, Jia Lan couldn't help but feel fortunate.

  Jia Lan thought that this might be the most sinister "trap" in the ruins that specifically targets spellcasters.

  In fact, if it were someone who knew nothing about astrology, this "Eberron Macro Galaxy Map" would not pose any threat.

  Just like Hugo and others, they just stared blankly at the gems on the dome, drooling, but without any discomfort.

  They just naively muttered how much they could sell these glowing gems if they could pry them off.

  However, they didn't know that these gems were insignificant compared to the value of this "Eberron Macro Galaxy Map" itself.

  "It seems that the secrets hidden in this secret underground temple of the Dragon Worship Cult are probably more mysterious than I expected..." When Jia Lan came to his senses, he found that the mercenaries had already started to move and headed towards the center of the hall.

  Just as Jia Lan was about to catch up, he suddenly discovered that there seemed to be strange patterns faintly engraved on the dusty ground.

  Jia Lan squatted down and brushed away the dust on the ground with his palm. The ground revealed under the dust surprised him, because the floor of the entire hall was made of a whole piece of finely polished, gorgeous deep purple obsidian.

  Stepping on it, it feels like standing in mid-air!

  On the obsidian ground, the lines of the magic arrays are intertwined, forming a series of rune arrays of different sizes.

  Looking around, if the entire floor of the hall is covered with such rune arrays of unknown purpose, then the number is probably no less than hundreds.

  A case of literary theft: this tale is not rightfully on Amazon; if you see it, report the violation.

  Such a complex and huge rune array system, even Jia Lan can hardly fully analyze its function in a short time.

  Jia Lan was about to look up and remind the mercenaries to be careful and not to touch any device in the hall at will, but saw Hugo reaching out to a huge crystal ball suspended on the altar in the center of the hall!

  "Don't touch it!"

  Hugojust touched the seemingly priceless huge crystal ball, and Jia Lan's exclamation scared him to death.

  Hugofroze on the spot, keeping the posture of reaching out to touch the ball, and all the mercenaries also kept their stiff movements and dared not move.

  There was silence all around, the mercenaries held their breath, and only each other's heartbeats could be heard clearly.

  After a while, Captain Kenmet raised the Yongming Light Staff, held a two-handed sword, and with one leg hanging in the air, he looked back carefully at Jia Lan who was shouting.

  "Don't move! Don't move! Don't move!" Jia Lan quickly ran to the center of the hall while reminding Hugo loudly.

  This made Hugo maintain an extremely awkward posture, and he didn't even dare to turn his head.

  When Jia Lan rushed to Hugo's side and found that everything was normal, the big stone in his heart fell to the ground, and everyone's heart almost jumped out.

  Hugo removed his hand from the jade-like golden crystal ball, muttering softly: "Mr. Jia Lan, I am a timid person, please don't scare me all the time..."

  Before he finished speaking, as soon as Hugo left the golden crystal ball, the crystal ball instantly shone like the sun, the light was so dazzling that it blinded people instantly!

  Only Jia Lan, who possessed the "Eye of Laian", survived. In shock, he quickly pulled Hugo, who was covering his eyes and screaming, away, and saw the golden Yaoshi crystal ball slowly rotating and rising into the air.

  As the golden Yaoshi crystal ball rose into the air, a circular golden light curtain spread out from the altar as the center, and the complex rune array on the ground spread like a snake, leaving a piece of spider web-like traces.

  The dust on the ground seemed to be pushed away by an invisible force, revealing the smooth obsidian ground, and a series of colored light beams lit up one by one as the rune array was conducted.

  The lighting range of the Yongming Light Staff is limited and cannot illuminate the entire hall.

  At this moment, with the help of the light from the golden crystal ball, Jia Lan finally saw this magnificent hall clearly!

  This hall is huge and perfectly circular. In the center is the three-story large altar with the golden crystal ball. There are five evenly distributed small altars around it. On each altar, there is a crystal ball of a human head.

  Starting from the dark purple obsidian on the ground, there are seven colors of obsidian: "purple obsidian, blue obsidian, red obsidian, blue obsidian, yellow obsidian, green obsidian, and golden obsidian"!

  In addition to the purple obsidian on the ground, the other six types divide the entire hall into six areas: "central" and "five directions". This can be seen at a glance from the different colors of light emitted by the rune arrays in different areas.

  The dazzling light rises to the highest point of the dome with the golden crystal ball, hovering like the sun, and the "Eberron Macro Galaxy Map" on the sky also dims and disappears.

  Everyone gradually adapts to the softened light and looks around blankly with tears on their faces.

  Jia Lan's face was livid. He felt that this huge rune array was most likely the "Nine Stars Array" that was common in the ancient Nesser Arcane Era!

  This was a composite rune array that integrated multiple functions such as teleportation, summoning, sealing, and space. Its complexity was so complex that no one except the builder and operator could understand it.

  Coupled with the "Eberron Macro Galaxy Map" on the dome, this "Nine Stars Array" became the "Nine Stars Zodiac Array", and its full name should be called "Nesser Arcane Nine Stars Zodiac Array"!

  Jia Lan felt that they seemed to have activated something incredible!

  "Sun, Gold, Wood, Water, Fire, Earth... No! There's also a lack of 'Moon' and two 'Hidden Glory'!"

  Jia Lan tried desperately to analyze the components of this rune array in his mind, but found that in addition to the "Ecliptic Five Stars" and "Sun", the "Moon" and the two "Hidden Glory" were nowhere to be found!

  Recalling that before the "Nether Array" was triggered, the "Eberron Macro Galaxy Map" on the dome did lack the "main star"... This means that this is an incomplete and broken Nether Array!

  Jia Lan was sweating instantly. He couldn't explain the horror of a broken Nether Array to the bewildered mercenaries.

  Although the "Nine Stars Array" can be simplified to "Seven Stars Array" or "Five Stars Array", Jia Lan has never heard that the broken "Six Stars Array" can still work normally!

  Any kind of Nether Array was regarded as a synonym for "mystery", "unknown", "complexity" and "danger" in Jia Lan's era. Even if it was a complete Nether Array, few spellcasters dared to easily control it, not to mention the broken array.

  They are currently in the central area of ??Nether, which is theoretically safe. As long as they don't step into the functional area of ??the "Ecliptic Five Stars", they should not trigger danger.

  However, even Jia Lan himself could not be sure whether this Naeser array was a complete "Nine Stars" or a simplified "Seven Stars". Assuming it was just a simplified "Seven Stars", the danger would be greatly reduced.

  But the problem is that the existence of "Sun" must mean the existence of "Moon". Now that "Moon" is absent, this incomplete and incomplete Naeser array is full of uncertainty. Once triggered, the consequences will be disastrous!

  Jia Lan swallowed his saliva and whispered: "Don't touch anything, follow me, don't step on any runes... Let's retreat!"

  Although they didn't know why, the mercenaries were frightened by Jia Lan's nervous expression. They followed Jia Lan's instructions, stepped on Jia Lan's footprints, and retreated carefully to the entrance, but...
