As for the issue between Blackmaw Castle and Brandon's Stone Castle, Jenn temporarily didn't care about it. He let Vilna send the Snake People Captain's magic weapon to Kadek just for this effect.

  Although he had only exchanged a few blows with the dwarf governor, Jann had already gained some understanding of Kardok's character. Cunning, greedy and fond of showing off, always having some small cleverness. So he was certain that after obtaining the pair of magical weapons, Kardok would not put them away, but instead take them out to satisfy his vanity. And indeed, as Jann had predicted, upon obtaining the two magical weapons, Kardok was overjoyed and eager to show them off every day in a museum. Even if he didn't do that, he still placed the two weapons in the living room for anyone to admire.

  In this way, the intelligence about these two magical weapons will definitely be transmitted to Hei Marenshi City. In the dark region, various forces have infiltrated each other and bought people to collect some intelligence. If Hei Marenshi City doesn't even have this skill, then they are absolutely impossible to survive in the gap between the three major underground forces until now.

  As for the commotion on the side of Brandon's Stone Castle, Jan didn't worry about it. In fact, he asked Vilna to go to Blackstone Watchtower not intentionally to bully her. It was because in the underground city system, each building needed a unit stationed there to function properly. The mutants were sent by Jan to search for the exact location of the transmission gate, and the undead creatures were responsible for protecting the underground city. Enya as deputy officer had many things to do, Biksi also led the goblins to dig tunnels all day, and as for Elise - her unit was also responsible for serving as a "prison", so the only one left was Vilna.

  Moreover, the Blackstone Beacon in Jan's underground city plays a very important role. In the event of a unit garrisoning, the Blackstone Beacon can increase the entire underground city's scouting range by +15% - this means that everything within a distance of 1,500 meters outside the underground city will be scouted and searched by the Blackstone Beacon. At the same time, this also means that if there is any movement on the side of Brandon Stone Castle, Jan can receive prompts from the system's intelligence information in the first place, rather than being completely unaware of it.

  So Jen let Villna guard the Blackstone Tower, not intentionally bullying her, but there was a real need. However, this also highlights the difference between games and reality. In the game, letting which unit guard where, just click and throw it over. But in reality, obviously, there is no such good thing, and Villna's reaction also gave Jen a wake-up call. Although it's also related to her being unwilling to be under Jen's command from the start, other people are not AI designed by game systems either. Enya is fine, even Becks probably has her own thoughts, if she goes too far, it will also cause backlash.

  It seems that in future constructions, these troubles should still be taken into consideration.

  Fortunately, however, the building Jan needs to construct does not have this requirement.

  "Ding ding………ding ding………ding ding…………"

  A rhythmic knocking sound came from beside my ear, and looking in the direction of the sound, I could see goblins waving their pickaxes in their hands, striking the stone wall with a loud noise. Before long, I heard a "crash" sound, and then a large piece of stone broke off and scattered all over the place. Immediately after that, another goblin came running over, chattering away, to clear away these stones.

  "Over there, right, just over there...... Ah, ah, ah, don't dig anymore, stop! Right! Be careful of the weight..."

  Behind the goblins, Bixie held a map, comparing its contents while giving orders to the goblins with gestures. As a dwarf, Bixie's influence was too low, and in the entire underground castle system, she could only command these few goblins. This was because the goblins were derivative products of the system itself, completely obedient to Jain's commands. So Jain let them listen to whoever they would listen to, no matter who it was, even if it was a pig head, so Bixie could instruct them.

  Can't help but admit, the dwarf's engineering is indeed top-notch. Zhan En considers himself a seasoned player and has done extensive research on building and excavating underground castles. However, after looking at Beike's blueprints, he was completely baffled, feeling like a primary school student reading a university research paper - it was like reading a heavenly book... But this is not surprising, as players' research on underground castles only goes as far as how to improve efficiency and increase damage output. In reality, the first thing needed is learning basic knowledge such as digging holes and load-bearing structures, which these players naturally don't understand. Otherwise, Zhan En wouldn't have almost dug himself into a hole at the beginning.

  Under Bixie's command, the goblins' excavation and expansion of space accelerated significantly. Before long, the original summoning crystal room, which was roughly the size of a guest room, had been expanded several times over, now approaching the scale of a courtyard. Moreover, Bixie cleverly utilized the hard granite as pillars to expand the underground space, making it much easier for Zhan Yan to do whatever he wanted.

  After confirming that everything was done, Becks finally let out a sigh of relief, looking around with satisfaction and nodding constantly. Unlike Vilna and Eris, Becks had already fully adapted to life in the underground city. In Becks' opinion, this place was much better than Dwarf City. Here, she could do things as she pleased without being scolded by others, and could even instruct others to act according to her own ideas. To know that in Dwarf City, only those venerable elders had this privilege, what could a young dwarf like herself do?

  But Becks was also very clear that her master was not a tolerant person, so every time Jenn gave orders, she would do her best to complete them and strive to do her best.

  While this was happening, Bixby discovered that she had also made a significant improvement. Although she used to have some talent, at that time she was still young and her personality was lively and playful, so she only paid attention to these things in a perfunctory manner. However, after being caught by Zain and taken to the underground castle, living every day with the question of "to survive or to die", Bixby had no choice but to carefully study and learn from her originally not-so-important lessons, fearing that if she wasn't careful, she would anger Zain and be cooked and eaten, which was a terrifying prospect.

  With such "survival pressure" driving her from behind, Beixi's progress in dwarf engineering is also rapid, and now Beixi's ability in this area is not much worse than that of an ordinary dwarf elder.

  "Reporting master, everything is ready."

  "Alright, I know, you stand behind me."

  "Yes."

  Bixie nodded as she listened to Zhan's words, then stood obediently behind him, her eyes wide with curiosity as she stared at the empty room in front of her. This was not the first time Bixie had seen her master's skills, and although there was clearly nothing in the space, he could make it into a perfectly complete building with just a few gestures, from tables and chairs to various decorations, everything was perfect. At first, Bixie was quite surprised, but after watching a few times, she got used to it. However, despite this, Bixie was still very curious about Zhan's construction skills, after all, every time he could create something that Bixie had never seen before, which opened up the little guy's horizons, and for Bixie, this was a rare opportunity.

  As for Becks' actions, Zhan didn't mind much. The little dwarf's curiosity wasn't a bad thing in his eyes. So he didn't say much and focused his energy, staring at the space in front of him. Soon, following Zhan's thoughts, rows of system prompts reappeared before him.

  "A summoning crystal has been detected, spatial expansion is complete. Do you want to upgrade to a Dark Sanctuary?"

  Blueprint: Dark Sanctuary (This is where eternal darkness resides, this is where the evil shrine lies, offer your sacrifices, open the gates of the otherworld, let the guardians of death descend upon this land, praise your greatness and glory) ——— Unlock: Large-scale Summoning

  Large-scale summoning.

  Upon seeing this, Zhan En couldn't help but let out a sigh. He had originally not wanted to unlock the large-scale summoning so early. After all, the things summoned by the large-scale summoning were all gluttons, eating a lot and consuming a lot, which was also somewhat unsustainable for Zhan En's underground castle. Originally, Zhan En's plan was to slowly cultivate small groups of summoned creatures, waiting until they formed a self-sufficient cycle before opening up the large-scale summoning. However, the appearance of the human patrol team forced him to advance his plans ahead of schedule. After all, these humans who could venture deep into the dark regions were not weak adventurers, and he urgently needed a powerful force to intimidate them. Ennoya's strength was still pretty good, but only mediocre. Iris' strength was formidable, but unfortunately, her identity was currently just that of a prisoner. Before her "re-education" was complete, Zhan En didn't have enough confidence to drive her. Vilna's strength was about the same as Ennoya's, and looking at her attitude, it was clear she wouldn't be willing to help him exert himself.

  So, launching a large-scale summoning and summoning a powerful summoned creature was an urgent matter for Zhan Yan. Anyway, he had plundered so many merchant teams before, and it would be enough to supply him for the time being.

  Unless it's a foodie reincarnation.

  "Upgrade Dark Temple."

  Zhan En thought for a moment, then smiled wryly and said in a low voice.

  "Upgrade Dark Temple, consumption - Ore (500), Mercury (500), Gemstone (500), Crystal (500), Gold (9000), please confirm."

  Confirmed.

  As Zhan's thoughts turned in his mind, the wind and clouds changed color quickly.

  The three summoning crystals in the center began to tremble slightly, and soon a black magic circle formed at their top, rotating and expanding rapidly. Immediately afterwards, the magic circle suddenly contracted and expanded, and the black magic circle burst open, enveloping the entire room.

  "Ah!!"

  Bix saw this scene, and she couldn't help but exclaim in a low voice. Because she clearly saw that wherever the law array passed, everything seemed to be covered with a layer of black fabric, becoming extremely dark, whether it was the ground, walls or ceiling, all were a mass of blackness, even the boundaries of up and down, left and right were somewhat indistinguishable. Not only that, but Bix also saw in the darkness, as if something was slowly and steadily moving, with a rumbling sound in her ears, looking around, the space in front of her seemed to be constantly moving, reorganizing, just like this room had been divided into dozens of pieces, being reassembled like building blocks, combining, transforming into new shapes...

  BOOM!!

  It was unknown how much time had passed, but only a dull thunder-like sound could be heard, and the ground trembled slightly. Immediately afterwards, the darkness that had shrouded everything seemed to recede like a tide, revealing once again the scenery that had been hidden from view.

  "Wow..."

  The little dwarf was astonished and stared with wide eyes, covering his mouth with his hand, gazing forward in disbelief.

  The space in front of me is completely different from before. The three summoning crystals have disappeared, replaced by a magnificent and grand altar. All the decorations inside the room are made of black obsidian, including the arched stone pillars on both sides and the floor tiles, giving off an air of mystery.

  However, the most eye-catching is still the altar in the middle. It's a pool of water that looks roughly the size of a swimming pool. Inside, you can clearly see the rippling waves and the magical glow of the pool water. And in the center of the pool water, there is a pair of giant stone hands, keeping their palms together. On the wall behind these stone hands, a six-pointed star is painted, with two concentric circles wrapping around it, adding to the mysterious and eerie atmosphere of the entire temple.

  "Breath..."

  Seeing this scene, Zhan En nodded in satisfaction, then he gritted his teeth and subconsciously rubbed his hands.

  So next is to see one's own luck!
