It's a world shrouded in darkness, and there's not a ray of sunlight in sight. Except for the occasional whimper in the distance, the silence was terrifying.

This strange scene made Duan Yun secretly vigilant. He tried to see where he was, but he was saddened to find that even with his own eyes, he could barely see within a foot.

In desperation, Duan Yun simply closed his eyes and walked into the distance with his spiritual power.

A mile away is a lonely city, with the words "City of Darkness" engraved in the center of the gate. A drawbridge connects the land at Duanyun's feet to the castle, and below the bridge is a fifty-meter-wide moat. The river was formed in an unknown way, it was so sticky that it couldn't flow, and there were objects of all shapes floating on it. Far away, a disgusting stench came to my face.

Frowning, Duan Yun walked along the suspension bridge towards the castle.

The moment he stepped onto the suspension bridge, Duan Yun suddenly felt that the unknown objects floating on the surface of the river seemed to shake in unison. Immediately after, a stream of green glow emerged from these objects, forming a ghostly spirit.

At this moment, Duan Yun finally understood why the river was so viscous. What kind of river is this, it is clearly the blood of the deceased that has not coagulated! And the object floating in the river is the corpse that has rotted for I don't know how many years!

After death, if there is a strong grudge, a unique spirit will be formed, which will be stored on the corpse, and once disturbed, it will attack. Ordinary warriors only pay attention to physical training, so they have no defense against this kind of attack from the spirit body, and they will soon be taken away from their souls and reduced to nourishment for the spirits.

This was not the case with an alchemist like Duan Yun. At their level, they basically have their own Danhuo, and where there is no sunlight, fire is the most effective way to dispel these evil spirits. Of course, the strength of the Danhuo is different, and the role it can play will be very different, but in any case, in such an environment, there is always a huge guarantee for holding the Danhuo.

This is the reason why the Spirit Tower is only accessible to alchemists.

Sensing that these geists were approaching him, Duan Yun smiled faintly, but he did not shy away from them, allowing them to burrow into his mind. Because he knew that in addition to the spiritual power seeds with fire attributes, there were also two more anti-heaven existences, the Tree of Mental Power and the Little Fire.

Sure enough, after seeing Duan Yun's inner world, the wandering spirits who were originally going to feast were suddenly shocked. However, just as they felt bad and turned to flee, a flame of terror instantly pounced, and in the flames was clearly discernible an inconspicuous seed.

A terrible scream sounded from Duan Yun's mind. After a few moments, everything was calm.

"This Spirit Tower is really an excellent place to enhance your spiritual power!" Feeling that the spiritual power seed had grown a lot, Duan Yun sighed secretly, he even had an urge to take the Spirit Tower away, although he also knew that this idea was unrealistic.

With such a big harvest, Duan Yun simply sat down and quietly waited for the prey that had thrown himself into the net.

These low-level geists have no intelligence, and their attacks are purely instinctive. Even if he saw the same kind of mud cow in front of him entering the sea, they were still like moths fighting fire, turning into a part of Duan Yun's spiritual power.

The green glow finally became scarce, and Duan Yun lost interest in staying any longer. He knew that there must be a more suitable existence in the castle, and what was in front of him was just a small test.

Walking into the castle, the broken streets suddenly appeared in Duan Yun's perception. On the ruins, you can see all kinds of tragic corpses everywhere. And the strange thing is that I don't know how many years have passed, these corpses have not decomposed, and even the expression of struggle when they died can still be faintly seen, presumably a strong prohibition has been set up in this castle.

Just when Duan Yun sighed at the generosity of this forbidden person, a heavy footstep came from far and near, and in this footstep, it was also mixed with the impact of tinkling metal from time to time.

Soon, the footsteps stopped more than a dozen steps away from Duan Yun. A group of soldiers in tattered armor appeared in front of him.

The soldiers were all dressed in the same attire, and although the armor was different, their eyes were dead gray and unrefreshed. If it weren't for the rusty spear in their hands that emitted a fierce murderous aura, Duan Yun would have almost thought that what appeared in front of him was a bunch of statues.

"There are no life fluctuations, it's actually ...... Corpse soldiers!" Duan Yun quickly knew what was coming, and although he had made enough preparations, he was still surprised.

Corpse soldiers are not as easy to deal with as ordinary armies. They are already dead, so they have no pain, let alone fear of death, and the reason why they can still act is because they still have a special spiritual power in their minds, and this spiritual power comes from the obsession with killing.

Since there is no other concern, the killing intention of the corpse soldiers is extremely strong. Once the target is locked, it will attack endlessly until the opponent falls. There is only one way to solve them, and that is to completely wipe out the remaining spiritual power in their minds.

"Trespassers of the Dark City, die!" the corpse leader stiffened out the words, his loyalty to the castle making him unable to forget his duty even after death.

And with this order, dozens of spears stabbed towards Duan Yun from all directions.

In desperation, Duan Yun had no choice but to use teleportation, so that he could avoid this deadly attack. But he also knows that this is not the way to go, his spiritual power will be exhausted sooner or later, and these corpse soldiers who are not afraid of death are tireless, and the results can be imagined.

"Xianglong Flurry!" Taking advantage of the fact that the corpse soldiers had not yet been encircled, Duan Yun decisively used the Xianglong Fist.

However, the next scene made Duan Yun dumbfounded. I saw that after the shrunken thunder dragons bombarded the corpse soldiers, they only made their bodies shake. And the jumping thunder arc didn't seem to have much effect, on the contrary, these corpse soldiers also made a sound of "lotus" in their mouths, looking extremely enjoyable.

"Damn, I don't know what kind of freaks these things are, their bodies are so strong!" Duan Yun scolded secretly while quickly thinking about countermeasures.

He originally wanted to destroy it with his powerful mental power. However, I don't know how many such corpse soldiers there are in the Dark City, and if they use up their spiritual power here, once another team comes over, they will no longer have the strength to fight again.

However, how to solve the current dilemma?

Just when Duan Yun racked his brains and couldn't find a solution, he unexpectedly discovered a problem. While the corpse soldiers continued to attack, the corpse general did not move, just stayed in place, emitting wisps of gray-white gas towards the surrounding corpse soldiers, this gas was as thin as a gossamer, if it weren't for Duan Yun's spiritual power to grow greatly, he wouldn't have noticed it at all.

The action of any object requires energy, and these corpse soldiers are like machines that never stop, and the reason must be this dead air. This discovery made Duan Yun's eyes light up, because there was a guy in his spirit bag who loved this bite very much.

The bored bones that were suffocating in the spirit bag were suddenly released. Originally, it was quite dissatisfied with the treatment it received, but now it felt this familiar breath, and its full of complaints was suddenly swept away, and it greedily rushed towards the dead air.

Lacking the replenishment of dead energy, the corpse soldiers suddenly withered. At the moment, there was only one corpse general left, and Duan Yun secretly had a plan in his heart.
