Gu Cheng's voice was not loud, but it was filled with cold chills and disdainful mockery. The banshee belonged to the extremely yin clan of the underground race, but she still couldn't stand the cold air conveyed by Gu Cheng, and couldn't help but shivered.

"No! Dear Lord Eternal Fallen! This is our small request, and we will pay you a satisfying reward for this request! This is a trouble that cannot be solved by our Hei Shui City. I hope you can help you!" I have to say that the banshee is very good at speaking, and he took the opportunity to flatter Gu Cheng. He deliberately said that it was a trouble that even Hei Shui City could not solve, but Gu Cheng could solve it.

"Ha......this is quite interesting! Tell me!" Gu Cheng had specially studied the background here before coming to Heishui City, and naturally he knew that this was the usual method of Heishui City. He would first be polite and then soldiers. If Gu Cheng continued to refuse, then he would prevent several banshees from suddenly jumping out while sleeping in the middle of the night to try to control their bodies, or ate something that was easily controlled by the mind, or were often harassed and attacked by some strange people, etc.

"Please be sure to believe our sincerity. We can assure you that this is just a humble request. Not far from the east of Blackwater City, there is a dungeon occupied by Nightcity. Originally, Blackwater City did not interact with this dungeon, but some time ago, Nightcity actually sneaked into the Elf Hall and stole a holy object... You also know that although there is no sunshine in the land of sinking, there is also a difference of 'day and night' because of the relationship between glimmer moss. Whenever the 'night' period, the light of glimmer moss will weaken sharply, which will form night. These nightcity plants have extremely strong lurking ability at night, and we sent the garrison of Blackwater City to enter the dungeon carpet-style search, but we cannot find the way to enter this dungeon."

Speaking of this, Navier was silent for a moment, looked at Gu Cheng without showing any displeasure, and continued: "Later, we discovered that these night walks will trade with some food merchants in Hei Shui City. We also sent some people who are good at hiding into the team, but these night walkers only allowed the merchant group to enter and negotiate transactions at each time, and the two people entering will be closely monitored. Therefore, we have no success in sending people who sneak into the dungeon to retrieve the holy objects. Therefore, we hope to use the powerful strength of the adults..."

"Let me get into the businessman team? Enter the dungeon to help you find the holy relics?" Gu Cheng saw the plot party's high-playing game live broadcast on the forum. He knew that in the dungeon, in addition to the night walk, there were also the blood-sucking species, the dark elves' mortal enemy, so the teams sent by the dark elves to look for holy relics were all gone but never returned. Of course, tasks like this that cannot be completed by "npc" were finally completed by players.

When he heard Gu Cheng's answer, Navier immediately smiled in surprise: "Yes, our strength and knowledge are naturally not as good as those of the adults. If the adults are willing to sneak into the night-walking dungeon, they will definitely find the holy objects for us!"

Gu Cheng suddenly frowned, not because of the Banshee's request, but because he received a system prompt.

[Triggering random hidden events - the trouble of Hei Shui City.]

[Task 1: The request of Blackwater City, enter the night farming dungeon to find the lost holy relics]

[Task 2: Solve the troubles of Blackwater City and explore the Nomori Institute.]

Gu Cheng thought about it, and anyway, the mission system also had a task of going to the night walk to plant a dungeon, so he simply followed both tasks. So he said, "Okay, I will go and see the situation."

Originally, seeing Gu Cheng frowning, Navier was worried about annoying the evil star, and she felt a little uneasy, but she didn't expect that Gu Cheng agreed to go downstairs in one go and said excitedly: "Thank you very much for your willingness to help. If you have any arrangements, please feel free to give me instructions!"

Gu Cheng just nodded slightly and asked casually: "This dungeon was occupied by the Yexing Clan, what about the other one? What's the situation?"

"Sir, in fact, another dungeon is more appropriate than a dungeon..." What Navir said is actually very simple. The dungeon of the Mysterious Forest was discovered because Blackwater City needed resources and entered the forest to mine. The dark goblins discovered a ruin on the way to dig underground veins. However, if that was the case, this was not a rare thing for Blackwater City.

The underground world is different from the surface world, and it is impossible to imagine how many historical relics exist here.

Due to the special nature of the underground, any place may have and exist ruins of ancient times or urban ruins. These places have various dangers, but also various wealth.

It is no exaggeration to say that no matter where you are in the land of sinking, you will sooner or later find a ruin or dungeon that is buried or sealed.

But no matter what it is, it will bring you rich benefits and rewards.

However, this ruin did not bring wealth to Blackwater City, but instead caused them to destroy a large group of sub-ethnic slaves and a large number of dark goblins. Neither the dark goblins they sent to dig out resources or the warriors who went to explore this ruins, they did not return from the mysterious ruins.

Later, the dark elves even deployed several of the strongest combat forces in Blackwater City.

But they still escaped from the ruins in a panic, but these dark elves were much better than those who had entered before, and at least came out alive. They found that this ruins might be related to some mysterious ancient puppet magic creature, and they could not deal with without the master-level trap science and engineering. And the Hei Shui City that met these two conditions could not be found at all, so they could only temporarily put the exploration of the ruins on hold. This stranding lasted for a whole year.

But this was not an easy decision for Hei Shui City. Because a huge underground vein was found behind the ruins, and it was rich in rare silver ore and refined gold ore. However, since the ruins switch was activated, whenever Hei Shui City sent people to pass by the ruins, they would be attacked by lasers and could not reach the vein behind. And even if the slaves were attracted to fire and allowed miners to enter the mine cave, some worn puppet robots would appear inexplicably. No one knew where they entered the mine cave. After that, more puppet robots would sound alarms.

Although Navier's words sound like this ruin is mysterious and dangerous, Gu Cheng knew that this was a level 50-60 copy, involving the gnome engineering school, a paradise for every engineering player to brush drawings - the "Normogen Institute".

Gu Cheng thought for a while and asked, "So... the traitor I am looking for went to which of these two ruins?"

Navier thought about it and finally decided to tell the truth: "My Lord Eternal Deep Fallen, I can't hide it from you... In fact, we don't know which ruin the man went to, but our people have seen him in both ruins, so we don't know where he is now."

"So... since that's the case, I'll go to the Normogen Institute first."

"Ah!? Ah!!" Banshee Navier was frozen by Gu Cheng's sudden change. Could it be that this "adult" was a deaf man and could not understand what he said? It was an extremely dangerous place. Even the strong man of the dark elf had no choice but to go in! The city lord only planned to explore the strength of this adult, but he never thought of letting him die directly...

"Don't worry, come out of the ruins, and then help you find the holy objects."

Please! That's all you need to have your life!

………

Seeing Navier's shock, a smile that was almost invisible flashed in Gu Cheng's eyes quickly, and then he said, "But I hope you can provide me with some materials so that you won't die in the trap..."

Navier had no reaction to Gu Cheng's similar jokes. She was already in a state of great success. She thought to herself whether this adult was really determined to go to the ruins? Or did he know the inside story about this ruins? Or was he a master who mastered the master's trap science and engineering at the same time? If this is the case, then you must report this matter to the city lord immediately!

Gu Cheng's decision naturally did not dare to disobey, so after understanding Gu Cheng's needs, he quickly returned to the Dark Elf Temple located in the deepest part of Hei Shui City and reported the news to the city lord. In fact, Gu Cheng did not offer any excessive conditions, but just asked Hei Shui City to provide him with some gold coins as a reward for helping Hei Shui City solve the trouble. As for whether to send people to enter the ruins with him, they would consider it themselves, and Gu Cheng had no objection to this.

After Gu Cheng took the money, he hid in the hotel and converted it into a player's identity to Le Youyou and asked her to help buy a lot of things and mail it to her.

The Hei Shui City responded quickly to Gu Cheng. In the afternoon of that day, Navier brought 5 banshees, 20 ogre warriors, and 50 sub-ethnic slaves to the hotel. For Hei Shui City, they deployed a very "conspicuous" combat power, but for Gu Cheng, the combat power of these people was not only the banshee, but the rest were cannon fodder.

"Mr. Reus, is this?" Sali asked in confusion when she saw the scene outside the hotel.

"We are going to go to a ruin in the Mystery Forest."

"Relics?" Sari is a resident of the earthly world and knows little about the remains of the earthly world.

"Don't worry, it's just like the mysterious and dark maze we passed before."

"oh."

Gu Cheng took Sali out of the hotel. Navier and others had been waiting for a long time, but none of them had any displeasure on their faces. Not only because Navier had told him not to annoy this adult before coming, but more because Gu Cheng's deeds have spread throughout Hei Shui City in the past two days. The residents here all knew that a bad star had recently arrived in Hei Shui City.

"Dear Lord Demon Fallen, we will follow you to the ruins and obey your orders." After saying that, Navier saluted respectfully.

The ogre warriors and sub-ethnic slaves brought by Navier were an unexpected surprise. It can be seen that the problem with the ruins is indeed a major concern of Hei Shui City, otherwise it would not have invested a lot of money. It was obviously trying to use Gu Cheng's power to take the opportunity to get rid of the trouble of the ruins. Of course, if Gu Cheng showed not enough strength to conquer the ruins, then these people would immediately turn around and escape. Just kidding, no matter how many low-level troops in Hei Shui City are, it is impossible to send dozens of people to accompany them to die.

After everything was ready, the group entered the Mysterious Forest, passed through the swamp in the center, and came to the dry and desolate gravel valley. Navier followed Gu Cheng and explained information about the ruins all the way to him. At this time, he pointed to a ruin located in the middle of two underground rocks and said, "It's there."

From the huge rocks, you can vaguely see a place similar to a building.

"Sir, if you move forward, you will touch the mechanism in the center of the rock, and there will be traps similar to laser rays. We have tested this kind of laser ray with a fine gold shield. A 30 cm thick fine gold shield will also be shot through at once. I'm afraid it will be an engineering laser of at least level 3 or above,"

Gu Cheng nodded. He studied many strategies for Nomogan's dungeon last night, and he was very familiar with the situation here. In addition, there are many "opportunistic" methods written by players.

"You guys back."

Navier also wanted to take the opportunity to see if Gu Cheng really had this strength, so she nodded immediately: "Sir, be careful!"

There are three mechanisms on the front of the Nomori Institute. According to the normal entry method, two entry-level engineering apprentices need to enter below the rocks on both sides of the left and right, turn off the switch of the laser ray, and then the team moves forward, and there is another switch under the rocks behind. At this time, advanced engineering is required to turn off the mechanism.

However, the great experts and "player parties" who exploit loopholes do not allow such harsh conditions. As noted members of engineering, they also have to enter the Nomore Institute to brush up on expensive design drawings. Therefore, the "brute force cracking method" was successfully developed! There is no need to master engineering, it only takes three goblin bombs above level 2 to do it!

When Gu Cheng decided to go to the Nomori Institute, he also specially studied the "brute force cracking method". Standing at the precise coordinate points developed by the players, Gu Cheng took out two goblin bombs.

"Go back a little longer!"

Everyone didn't know what Gu Cheng was going to do, but they took a few steps back at his request.

The difficulty of the "Brute-Break Resolve Method" is that the two agencies must be blown up at the same time. If they throw one, blow up one and the other will be triggered immediately. However, there can only be one person on the rock at the critical position. Due to habits, everyone's left hand is not as flexible as the right hand, let alone throwing bombs into two very tricky positions.

"call--"

Gu Cheng took a deep breath and saw a lot of videos and strategies, but this was his first time to let him do it.
Chapter completed!
