They are used in equipment forging to improve the quality of the crafted equipment.

But energy crystals are very rare, and it's difficult for ordinary players to obtain them.

Since Il said so, it means this staff still has room for improvement, and he knows where to get energy crystals. That Yi can't be hasty, it's better to spend some effort and energy with Il to make it more perfect!

Then, Er nodded and said to Zhang Yi, "Alright, then go to the [City of the Dead] and find me a first-order energy crystal. I only know that place is buried with a large number of energy crystals, but I don't know exactly where they are."

"The City of the Dead"

Zhang Yi opened the map and searched by name to find the City of the Dead. He discovered it was a map for levels 15-30!

The map introduction says that the Necropolis is divided into three layers, and the corresponding monster levels for each layer are different. Even the lowest level, the first layer, has monsters with levels ranging from 15 to 20!

It seems finding an energy crystal won't be easy.

However, Zhang Yi from his past life had also heard of the Nether City.

As I recall, although this map is said to be dangerous, with high-level undead monsters that are far stronger than ordinary creatures, it is also rumored to contain countless treasures. Former players called it the "Treasure City" of the beginner area.

Besides high-star treasure chests, monsters in the Necropolis also have a chance to drop extremely rare suit armor!

Countless players have perished within it, while others have reaped immense rewards.

Zhang Yi then said to Er: "Alright, you wait for me. I'll get the energy crystal back and give it to you."

At this moment, Il suddenly said, "Warrior, since you intend to go to the City of the Dead, I have something I would like to ask of you."

Zhang Yi was taken aback. This was the rhythm that triggered a hidden quest! Because Il had said this much, it was clear that there was a mission he could entrust to the player. However, there wasn't a question mark icon above his head!

Then, Zhang Yi asked, "What's the matter"

"The undead in the City of the Dead have a lot of materials on their bodies that can be used to forge equipment. Could you go to the City of the Dead and hunt down those undead, and bring me some materials back"

As soon as Er's words fell, Zhang Yi's ears were filled with a system prompt that made his heart race.

"Ding~ Congratulations on triggering the advanced hidden quest 【Guardian's Acquisition】. Do you accept the quest (This quest is of high difficulty and requires a significant amount of your time and energy to complete. The system advises that if you are not a very patient person, please do not accept this quest, as failure will result in severe penalties.)"

It's actually a hidden quest! And it's an advanced hidden quest for "Guardian" which Zhang Yi had already completed.

This was definitely an unexpected harvest, and it wasn't within Zhang Yi's expectations. Because in his past life, this advanced hidden quest wasn't discovered by any players, even those who completed the [Guardian] hidden quest.

Because of this mission, the stealth level is too high. If Zhang Yi had just chosen not to obtain the energy crystal and directly taken the staff from Il, he would have definitely missed out on this hidden quest!

Advanced hidden missions, more valuable than hidden missions!

Excitedly, Zhang Yi didn't hesitate at all. He immediately accepted the mission. Such a once-in-a-lifetime opportunity; even a fool wouldn't give it up.

The next moment, the system's prompt sounded —

"Ding～ Congratulations on receiving the advanced hidden quest [Obtain Rare Materials], details can be viewed in the quest interface!"

Open the task pane quickly —

Task difficulty coefficient: 440

Description: It is said that the undead in the City of the Dead contain a large amount of rare materials that can be used to forge equipment. Please follow the map guide to the City of the Dead, hunt the undead residing in the city, and obtain three rare materials from them: energy crystals, divine bones, and undead consciousness.

Mission progress: First-tier energy crystals 0/10 (All monsters in the City of the Dead have a chance to drop), God bones 0/1000 (Skeleton mobs in the City of the Dead have a chance to drop), Soul essence 0/1000 (Undead mobs in the City of the Dead have a chance to drop).

Reward: Unknown

Time remaining: 7 days

Failure Punishment: Level -3 (Failing to deliver sufficient materials to the blacksmith Il within the designated time frame results in mission failure).

Well done, it's a 440 difficulty coefficient task! For Zhang Yi, who just finished a 120 difficulty coefficient task, this is quite a challenge!

And this task... damn it, it requires collecting 10 first-grade energy crystals! With that many energy crystals, plus some other easier-to-obtain materials, and a bit of money, you could almost craft a 4-star piece of equipment at the blacksmith's right now!

However, this also proves that the investment in the task is so huge, its reward is simply guaranteed to far exceed the value of 10 first-order energy crystals!

Fortunately, there is plenty of time for the task. A week, seven days to collect these materials, should be enough.

Of course, this is just Zhang Yi's personal idea. Advanced hidden tasks are not as easy to complete as he imagined...

After receiving the mission, Zhang Yi bid farewell to Er.

Looking at the time, it was just six o'clock in the evening. Zhang Yi didn't rush to go out and execute his mission immediately because he still had some things to deal with in his bag.

At this time, many players were busy doing tasks and grinding monsters in the wild all day. They gradually returned to the safe zone one after another, so at this moment, I hope the town would be bustling with people, lively and extraordinary.

Many players set up stalls on the streets to sell equipment or skill books they don't need that they got from slaying monsters.

Zhang Yi also randomly chose a crowded spot, set up a stall, and took out the 1-star equipment and three white skill books from his bag. Then, he lit up his ID card and, relying on the reputation of "A Promise to the City," instantly sold all these things, accumulating a revenue of 2 gold coins!

Of course, the main reason it sold for so much was still those three skill books. Even white-quality ones were very valuable in the early game stage when all players only had one skill from their initial class transfer.

After taking care of his own things, Zhang Yi also browsed the other stalls. He just wanted to browse casually and buy something good at a reasonable price, if he didn't find anything suitable, it didn't matter. Unexpectedly, Zhang Yi really found a good thing——
