I didn't feel it when I was in the water before, but now that I entered the sewer, what I smelled was not the stench of decay, but the pungent smell of blood! Du Yuqi squinted his eyes to adapt to the dark environment, and then he saw that Kerr, who was exploring the way ahead, turned back, holding a ball of moss that emitted a faint fluorescent light in his hand, which could serve as a lighting.

With the help of the dim light, Du Yuqi could clearly see that the ground of the sewer was covered with large pools of shocking blood. The blood was coagulated into clots and appeared black. It was obvious that in order to attack the city of Kuva not long ago, the enemy massacred the goblins who stayed behind here, and the blood was washed here through the drainage system in the city. Although some time had passed, it still showed the enemy's cruelty and viciousness!

Witnessing this, Du Yuqi was just shocked, but Kerr had already knelt on the ground, covering his face with his hands, his whole body shaking violently, and a suppressed sound came from the depths of his throat. It was obvious that he could not control his emotions and burst into tears violently. It was extremely distressing!

Although the seriously injured Mari seemed to have no reaction, his whole body had begun to radiate high temperature. Although there was no direct contact, Du Yuqi, who was standing half a meter away, felt as if he had come to the side of a blazing fire, and even the air was constantly churning.

Du Yuqi knew that it was better to ease the situation than to block it, so he did not urge them. Although he had no sense of belonging to the city of Kuva and could not feel the pain of the two goblins, he could not stop his murderous intent towards these enemies. After their emotions calmed down a little, he said:

"We will immediately seek retaliation from the enemy for this blood debt!"

After hearing Du Yuqi's words, the two of them rushed forward with red eyes as if they were injected with chicken blood. Du Yuqi sighed, knowing that he was overstimulated again, and hurriedly caught up with them and tried to persuade them, and finally calmed their emotions to just right.

The purpose of building the sewer in Kuva City is to drain sewage, not to give people the opportunity to sneak in, so the journey is quite difficult. It is inevitable to climb or even destroy in order to pass smoothly. In this dark, gloomy, damp and dirty place, they only walked about five or six hundred meters. The three of them were sweating and gasping for breath.

Finally, under the guidance of the old goblin Mari, the three of them came to the bottom of a sewage ditch. Then Kerr, who was good at hiding, climbed up quietly and began to gather information.

He was gone for a full half hour. Even the old man, Brinmali, who was determined to die and was very patient, was getting very impatient. Kerr finally came back panting, his face was a little ugly, but his words were full of joy:

"There are still many people alive. Only a few were massacred. It seems that these bastards are planning to stay here for a long time, so they need a lot of coolies to work for them. At least two or three hundred people are imprisoned in the holy land!"

After hearing what Kerr said, Mari couldn't help but said happily:

"Imprisoned in the holy land? The holy land seems to be a Jedi, but there is actually a way to get down the mountain quickly! As long as we kill the guards, our people will have a great chance of escaping!"

As mentioned before, the city of Kuva was built on the mountain, with a river in front and a cliff in the back. To use a figurative metaphor, its cross-section looks like a "4". The entire city of Kuva was built on the slope of the "4". The cliff in the back is the vertical line behind the "4". It looks like a Jedi, and the holy place is on the top of the mountain.

But in this seemingly remote place, there is still a secret passage hidden quietly!

To be precise, this secret passage is a zipline carefully built with magic. It is usually clinging to the cliff and covered by vines, so it cannot be seen at all. However, once it is activated and straightened, it will form an escape passage, and then you just have to slide down the zipline. The two or three hundred people captured may seem like a lot, but in fact, if the zipline is used, it will be enough to evacuate everyone in a short time.

Such a secret passage is easier said than done. It is simple to say, but it takes a lot of manpower and material resources to actually build it. More importantly, the secret passage must be kept secret. If it is known to everyone, then why bother to build it? Therefore, even the new generation like Kerr does not know about it. Only old guys like Mari can know it well.

Du Yuqi frowned and said:

"What about the guarding here?"

Du Yuqi had heard before that the enemies attacking this side did not seem to be mainly composed of rat-headed people and puppets, but a kind of cyborg, a combination of flesh, rubber, and metal parts, driven by crystal energy. Their individual combat power was quite strong, they could use various weapons, were not afraid of injuries and ignored pain, but he did not know much about the specific situation.

Kerr whispered:

"At this time, all normal people have rested. The remaining guards are these mechanical monsters driven by crystal energy. They don't know fatigue or pain. At the same time, they have laid out track patrol self-propelled electric guns, early warning mechanical insects, G17 predator paralysis type and the like, and even an infrared crystal block monitoring system for body temperature scanning! However, these protective facilities are also placed on the periphery, and only the vital parts are equipped with these energy-consuming things."

Du Yuqi said in a deep voice:

"But placing these things in vital areas is already a headache, especially the infrared crystal detection system for body temperature scanning! This thing can be said to be the nemesis of people like you!"

Kerr whispered:

"Because I have the ability of 'Danger Insight' after my job change, I can sense the warning range of these traps and mechanical devices one step ahead, and I also have the ability to completely hide over a short distance, so I can barely move through them. Even so, I dare not get too close."

Du Yuqi smiled bitterly and said:

"So if you put it that way, it would be almost impossible for us to get close to the enemy's vital areas and deliver a ruthless blow?"

Kerr sighed and said:

"It is possible. If the enemy arranges it like this, it will actually encircle their key areas invisibly. As long as there are various early warning and protective facilities, then most of them are the areas they want to guard against."

"At the same time, I also discovered one thing, that is, the mysterious enemy occupying this place seems to have some problems. They seem to be tightening the supply of energy."
