Lin Wu spent some time testing out the ghosts that were around. He discovered that physical attacks did nothing to the ghosts, merely making them flicker for a bit before their bodies returned to normal.

He then tried using spirit Qi and amplified his tail with it before attacking them. This time the effect was similar, except that the ghosts were pushed back. Though not as much as the force should have.

Lin Wu then used the wind attribute spirit Qi and send out wind blades from his tail, and saw that while the ghost were uninjured, they were still pushed back.

"Hmm… so physical attacks are useless, while the spirit Qi attacks can only keep them at bay. What about my radiation though?" Lin Wu wondered.

He then activated his innate skill Radiation manipulation before attacking the ghosts with it. The effect this time was the same as when he had used physical attacks. The ghosts were unaffected, and the radiation simply passed through them.

Though there were some distortions that Lin Wu sensed. He used his radiation perception to see the ghosts and discovered that they didn't let out any radiation. But even then he could see the spirit Qi being pushed around them as they passed.

"So they have a different type of energy that they function on… that is what I am observing here." Lin Wu muttered to himself.

Doing a few more tests, he thought back to his past world's knowledge.

'Don't they say lightning is effective against ghosts?' Lin Wu remembered.

But then he realized he couldn't actually use any lightning yet. His Immortal Sky shaker Art was not at the third level yet.

~Sigh~

"Guess I'll have to wait for Shirong…" Lin Wu muttered.

He thorough the data that the system had stored about these ghosts and read up on how to deal with them.

The methods to deal with the Marsh Ghosts were quite less. The first method was to use a defensive talisman which prevented them from coming close to you, the second was to use a ghost banishing talisman which could exterminate them, the third was to use Qi skills to keep them at bay and the final was to use items of extreme yang to repel them.

Lightning was one of the things mentioned in it, but there weren't many people who could use a Heavenly element like lightning, thus all they could rely on were talismans and some spirit tools in this case.

Even fire was ineffective against these ghosts as the yang in that was not enough to affect them.

"No wonder all the kingdoms are helpless against the ghosts. While they can get the lightning attribute treasures and even cultivators who can use them, they are simply far too less to deal with such large numbers. Even the ghost banishing talismans would burn a hole in the pocket of the kingdoms if they kept on using them." Lin Wu said upon reading the information.

'Though the question still stands… why don't they attack me?' Lin Wu thought.

After a few minutes of thinking, he realized the problem may be his physique.

"Wait, a minute… could it be due to my crystal form? What if I revert to the organic form?" Lin Wu said before changing his body to the organic form.

~SKREEE~

The moment Lin Wu was fully in his organic form, the ghosts let out a high pitched screech and rushed towards him. They passed through his body and let out a faint chill while doing so.

"Whoa, whoa, whoa!" Lin Wu said upon seeing the explosive reaction of the ghosts.

He had known that the ghosts don't actually cause physical harm and thus didn't care that they rushed him. But when they passed through his body, he felt uncomfortable. In less than a minute, over a hundred ghosts had passed through him and now he was getting a headache.

"Oof~ it's like I'm having a brain freeze." Lin Wu said before deciding to change back.

The moment he returned to his crystal form, the ghosts stopped screeching and went back to their previous state. It was as if nothing had ever happened. Though when Lin Wu checked the number of ghosts, they had gone down.

"Huh… where did they go?" Lin Wu wondered before checking the map, unable to see any difference.

"System, do a full scan of my body and check for abnormalities." Lin Wu said upon being unable to find anything wrong himself.

~Ding~

CHECKING HOST VITALS: Scanning

"Hmm… so nothing there. Perhaps it is due to my cultivation base? Yu Guowei did say that Ji Quan was resistant to the ghosts unlike the other cultivators of their team." Lin Wu murmured.

Having come to this conclusion, Lin Wu thought to check out the rest of the forest. There were far too many things here, and he wanted to see if he could find some of the treasures that could be found here.

Two days passed like this and Lin Wu decided to return. He had mapped out around thirty percent of the Dread Coil Marsh in this time and could have said to be covered the entire part that existed within the borders of the Ivory Heron Kingdom.

Lin Wu had also obtained a few spirit herbs and materials that were good. The herbs that were more low quality were directly eaten by him while the better quality ones were saved for later. He reckoned they would be better refined into pills.

As for the materials, he just kept them as they were something that would come in handy later as rewards.

'Seems like a good enough harvest for now. I'll find more with Shirong later, anyway.' Lin Wu thought to himself before taking flight.

He had gotten bored of the dark and gloomy environment of the marsh and wanted to be above the trees in the sky.

~Whoosh~

~rustle~

The trees moved while some of them were directly uprooted by Lin Wu's flight. When he was gone though, a few people had appeared out of the fog in the marsh.

"Did a new Nascent soul realm beast appear in the marsh?"
