In the world of Apocalypse, energy crystals are a rare forging tool that can enhance the quality of forged equipment. However, these crystals are extremely scarce, making them difficult for the average pyer to obtain.

  Since Ili mentioned it, it means this staff still has room for improvement, and he knows where to find energy crystals. Zhang Yi decided not to rush and was willing to invest time and effort to have Ili perfect it.

  Ili nodded and said to Zhang Yi, "Alright, go to the Undead City and find a Tier 1 Energy Crystal for me. I only know that pce is buried with many energy crystals, but I don't know their exact locations."

  "Undead City, huh?"

  Zhang Yi opened the map and searched for Undead City, finding it to be a level 15-30 map!

  The map description indicated that Undead City is divided into three levels, each corresponding to different monster levels. The lowest level, the first yer, has monsters ranging from level 15 to 20!

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

  However, in his previous life, Zhang Yi had heard of this pce called Undead City.

  He remembered that although the map was dangerous, with undead monsters having high levels and stronger combat power than typical monsters, it was also rumored to be filled with countless treasures, known as the treasure city of the novice area by pyers of the previous life.

  Besides high-star treasure chests, monsters in Undead City also had a chance to drop extremely rare set equipment!

  Many pyers had lost their lives there, but some had also made a fortune.

  Zhang Yi said to Ili, "Alright, wait for me. I'll bring back the energy crystal for you."

  At that moment, Ili suddenly said, "Warrior, since you pn to go to Undead City, I have a favor to ask."

  Zhang Yi was taken aback. This was the trigger for a hidden quest! Ili's words clearly indicated a quest could be entrusted to pyers, but there was no question mark above his head!

  So, Zhang Yi asked, "What is it?"

  "The undead in Undead City have a lot of materials that can be used for forging equipment. Can you hunt those undead and collect some materials for me?"

  As soon as Ili finished speaking, Zhang Yi heard a system prompt that made his heart race—

  "Ding~ Congratutions on triggering the Guardian's advanced hidden quest [Acquire Rare Materials]. Do you accept the quest? (This quest is quite difficult and will require a lot of your time and effort. The system advises that if you are not a very patient person, do not accept this quest, as failure will result in severe penalties.)"

  It was indeed a hidden quest! And it was an advanced hidden quest of the Guardian, which Zhang Yi had already completed!

  This was an unexpected gain, not within Zhang Yi's expectations, because in his previous life, this advanced hidden quest had not been discovered by pyers, even those who completed the Guardian's hidden quest.

  The task was too well-hidden. If Zhang Yi had chosen not to obtain the energy crystal and directly taken the staff from Ili, he would have missed this hidden quest!

  Advanced hidden quests are more valuable than regur hidden quests!

  Excited, Zhang Yi didn't hesitate and immediately accepted the quest. Such a rare opportunity wouldn't be missed by anyone.

  The next moment, the system prompt sounded—

  "Ding~ Congratutions on accepting the advanced hidden quest [Acquire Rare Materials]. You can view the details in the quest interface!"

  Quickly opening the quest interface—

  [Acquire Rare Materials] (Advanced Hidden Quest):

  Quest Difficulty: 440

  Description: It is said that the undead in Undead City hold a rge amount of rare materials that can be used for forging equipment. Follow the map guidance to Undead City, hunt the undead residing there, and obtain three types of rare materials: Energy Crystals, Divine Bones, and Undead Knowledge.

  Quest Progress: Tier 1 Energy Crystal 0/10 (All monsters in Undead City have a certain chance to drop), Divine Bone 0/1000 (Skeleton-type monsters in Undead City have a certain chance to drop), Undead Knowledge 0/1000 (Undead-type monsters in Undead City have a certain chance to drop)

  Quest Reward: Unknown

  Remaining Time: 7 days

  Failure Penalty: Level -3 (Failure to collect enough materials and deliver them to the forging master Ili within the specified time will result in quest failure)

  Wow, a quest with a difficulty rating of 440! For Zhang Yi, who had just completed a quest with a difficulty rating of 120, this was quite a challenge!

  And this quest... damn, it requires collecting 10 Tier 1 Energy Crystals! With so many energy crystals, plus some other easily obtainable materials and some money, you could almost forge a 4-star piece of equipment at the Bcksmith Shop at this stage!

  However, this also proves that the investment in the quest is so significant that its reward is certainly far beyond the value of 10 Tier 1 Energy Crystals!

  Fortunately, the quest time is ample, with a week, seven days to collect these materials, which should be manageable.

  Of course, this was just Zhang Yi's personal thought. Advanced hidden quests are not as easy to complete as he imagined...

  After accepting the quest, Zhang Yi bid farewell to Ili.

  Checking the time, it was just past six in the evening, and Zhang Yi didn't rush to execute the quest immediately, as he had some items in his bag to handle.

  At this time, many pyers, having spent the day doing quests and fighting monsters in the wild, were returning to the Safe Zone one after another. Hope Town was bustling with activity.

  Many pyers set up stalls on the street, auctioning off equipment or skill books they didn't need, which they had obtained from fighting monsters outside.

  Zhang Yi also picked a crowded spot, set up a stall, and took out the 1-star equipment and three white skill books from his bag. Leveraging the reputation of "Yinuo Qingcheng," he quickly sold everything, accumuting 2 gold coins!

  Of course, the main reason for earning so much money was the three skill books. Even though they were of white quality, at this early stage of the game, where all pyers only had one skill from their job transfer, they were still very valuable.

  After dealing with his items, Zhang Yi browsed other stalls, thinking he might buy something good if the price was right. Unexpectedly, he did find something valuable—

  [Intermediate Fireball Spell] (Green Skill Book for Mages and Beastmasters)!
