As he walked to the front of the altar, a cold mist mixed with chilliness hit him in the face. However, Zhan En did not retreat because of this, on the contrary, he carefully examined the strange sculptures in the water pool in front of him, as well as the texts, patterns, and spell arrays behind them. At the same time, he tried his best to retrieve all the knowledge about large-scale summoning from his mind, one by one, to compare and ensure that he could achieve the best effect.

  It's no wonder that Zhan is so cautious, large summons and ordinary summons are different. The modification made by Zhan in the system to increase the rare rate by 100% did not help with large summons, because large summons only produce rares - the problem is whether they produce ordinary rares or super rares.

  This means that when players put in a large amount of resources they've worked hard to accumulate, what they get is likely something that can easily be summoned on a daily basis, rather than a truly rare and powerful summon. Although the creatures summoned from the Dark Temple are stronger than those summoned from Summoning Crystals, for players, the difference between monsters summoned with 1x resources and those summoned with 10x resources is only about +3 in strength, which is really hard to accept.

  What's more, Zhan En had to do the same thing. In order to avoid going bankrupt as soon as his large-scale summoning creature appeared, he had to reduce the input of gems. However, if the gem that controls the amount of food is put in too low, it is very likely that a non-large-scale summoning creature will be summoned, and this possibility is very high.

  Just like 7777 doesn't necessarily mean a big win, but 4661's chances of winning big are obviously much lower.

  Zhan En narrowed his eyes, gazing at the resources in front of him. After summoning the alien and building the Dark Temple, his resources had decreased once again. If he were to undertake another large-scale construction project, Zhan En feared that for a very long time, he would have to seal off the underground city and let the Goblins search for resources on their own.

  The Dark Temple is open, please cast in summoning materials.

  Staring at the system prompt in front of him, Zhan En fell silent for a moment before reaching out his hand to start adjusting the resource allocation one by one.

  Large-scale summoning requires significantly more resources than ordinary summoning, with a minimum of 500, which is almost equal to the amount of resources in an ordinary summoning of medium to high quality.

  Investing in Mining Stocks (2000)

  Add mercury (1500)

  Invest 500 gems

  Crystal Infusion (3000)

  He readjusted the amount of materials he put in, and Zhan Yan furrowed his brow. According to the data he got from the model, 3000 crystals was the minimum number required to maintain a large-scale summoning creature. If it was any lower than that, then it definitely wouldn't be able to summon one. However, compared to before, this time Zhan Yan emphasized a form that mixed physical and magical attacks, and the initial attack power of the large-scale summoning creatures wasn't low at all - even the worst ones were at least three-star level. If he only focused on either physical or magical aspects, then it would really be too wasteful.

  As for the physical aspect, the 500-gem physique is definitely higher than that of ordinary summoned creatures, but among large summoned creatures, it can only be considered mid-to-lower tier. From this, we can see that this time's large summoned creature may have some shortcomings in terms of defensive capabilities... This point is also unavoidable.

  As for the other aspect... Zhan En hesitated for a moment, and finally added 3 units of sulfur and wood, which can increase the rare enhancement rate of large summons. Of course, generally speaking, players only need one of sulfur or wood, but to ensure the success rate of enhancement, Zhan En reluctantly added both sulfur and wood.

  Everything is ready, let's get started.

  After making the decision, Jian took a deep breath again and recalculated. It's no wonder that Jian was so tense, after all, the resources he had accumulated now were obtained when Jian attacked the underground merchant team before. Except for these things, he could not form a self-sufficient system for the time being, and the "offerings" in Brandon Stone Castle were even a bit insufficient to maintain the daily operation of the underground city. If he didn't summon a large-scale creature this time, it would be equivalent to wasting nearly two-thirds of the resources of the entire underground city. At that time, Jian might have no choice but to take his troops to rob and plunder.

  After all, even if they are both rare, the rare ones built by Da Jian and Pu Jian are two different concepts.

  Resource investment confirmed, summon?

  Summoning.

  As the thoughts flashed through Zhan's mind, the resource numbers in front of him began to jump rapidly and disappeared in the blink of an eye. Immediately afterwards, the dark temple in front of him also started to move - the ground began to shake, and the darkness at the depths of the originally pitch-black temple became even thicker, giving people a feeling as if they were being wrapped in some kind of dark, viscous substance just by standing there.

  The bright red six-pointed star array on the wall began to flicker, and the stone giant hand that had been closed slowly opened, causing the originally calm pool water to start churning and splashing, producing a sound of flowing water. Immediately afterwards, dazzling brilliance radiated from within, and a series of golden lines condensed like a physical entity, changing, entwining, and gradually taking shape as if weaving something together...

  It was unclear how much time had passed, maybe a few minutes, over ten minutes, or perhaps only a few seconds. The light dissipated, revealing the existence inside to Zhan En's eyes. However, upon seeing the summoned creature in front of him, Zhan En's face did not reveal joy or depression, but rather confusion.

  "What is this?"

  All that was visible in front of Zhan was a huge metal egg, about the size of a person. The overall color was silver and white, looking like it was cast from some kind of metal. On its surface, there were circuit-like lines intersecting with each other, formed by dark iron condensate, resembling the roots of an old tree entwined around the metal egg. In addition to this, a rough horizontal line could be seen in the middle of the huge metal egg, as well as a clock ticking away with a "tick-tock" sound, making it look even more like a timed bomb. Moreover, upon closer inspection, a bright golden light flickered inside the metal egg, looking particularly beautiful and elegant.

  "Wow..."

  Bixie gasped in amazement at the sight of the metal egg, her passion for engineering as a dwarf being unmatched. She had a soft spot for things that looked like technological creations. At this moment, Bixie curiously approached the metal egg, observing it carefully before turning to ask Jain.

  "What is it? Master?"

  "I'm also unclear..."

  In response to Becks' curious inquiry, Zhan shook his head and refocused his attention on the metal egg, soon seeing detailed information floating beside it.

  Mysterious Egg (Unknown)

  Quantity: 1 piece

  Attack: ??

  Defense: ??

  Special Ability: Incubation (No one knows how deeply the uncertainty of multiple probabilities affects, just like when someone complains "My wife is a complete idiot" this sentence may be transmitted through a wormhole to another universe and trigger a prolonged war with countless casualties. Because the multiverse is so wonderful, we must remind you at all times that no matter how difficult the situation, never forget to bring your towel) —— Can incubate one summoned creature, remaining time: 739 hours

  What the hell is this?

  Looking at the metal egg in front of him, Jian's eyes widened. Although he was indeed a seasoned player, the rare summons in the dungeon system were countless. Even Jian couldn't remember every summon's information, let alone the resources required for large-scale summons that limited his collection. So, when faced with this mysterious metal egg, Jian didn't know what to say either. He reached out and placed his hand on the metal egg, carefully recalling various posts he had seen on the forum.

  In many cases, forums are the best source of intelligence. Many players will post their rare summons to show off, with all sorts of strange and bizarre creatures inside. However, even so, Jian was unable to find what he needed from them. At least in the posts he had seen, there didn't seem to be anything like this, not even similar ones.

  Is it a dragon?

  Zhan En immediately negated his own imagination, the consumption required by the dragon species was enormous. Generally speaking, even if 9,000 crystals were invested, it wasn't certain that a dragon species would be produced. His 3,000 crystals could only guarantee the baseline for a large-scale summoning creature. If he had bad luck, he might not even be able to maintain the baseline. Moreover, this didn't seem like a dragon egg at all; from the inside out, it gave off an explosive technological aura...

  Forget it, anyway, we'll know once they hatch.

  Thinking of this, Zhan En could only shake his head helplessly. 739 hours was neither long nor short, almost a month's time. If it were in the past, he would calm down and wait for it to pass. However, the current situation is different from before. The Black Onyx City and the Brandon Stone City will likely have problems soon, and with the addition of humans, the entire Northern Territory's situation will become even more chaotic. This month's time, I don't know if it's enough for myself to buffer. If not, which direction will things develop in?

  Unfortunately, things in the world often don't develop as people wish. In just a few days, Zhan En received some very troublesome news from Weiruna...

  The army of Hei Maren City has been mobilized.
