Zhang Menglong spent an hour experimenting with his exorcism techniques on two undead warriors, ultimately obliterating them completely with the brilliant light of the Sun Scripture.

Of course, their deaths were not in vain, as Zhang Menglong drew several conclusions from it.

1. Ghosts are not afraid of ordinary light.

2. Methods for dealing with Western ghosts or Eastern ghosts both have some effectiveness against these undead creatures, but vampires and werewolves do not fall into this category.

3. Ghosts can feel pain.

4. Ordinary people cannot touch the undead of a 3.5-dimensional world, nor can the undead directly affect three-dimensional beings, but they can attack the souls of living beings or demon beasts through energy fields.

5. Based on the fourth point, at most, Nie Xiaoqian and Ning Caichen can only have a platonic spiritual relationship.

...

"Brother Zhang, you really have a way—being able to deal even with the undead!" Kong Lan now viewed Zhang Menglong as if looking at a deity.

He had just tried, and no matter which method he used, he couldn't even touch those undead warriors, let alone injure them. If he had come in alone, he surely would have met his end immediately.

But Zhang Menglong seemed to have a hundred ways to deal with them, as if possessing godlike abilities!

This made him even more worried about his father. Although his father was at the peak of the Demon Saint realm, encountering these undead creatures would still mean a dire fate.

Of course, he might be able to escape from these relatively weak undead, but he had obtained a lot of intel from their mouths just now.

The undead creatures of this world come from several other worlds, and their total number is almost no less than the humans and demon beasts of Haotian Continent.

The rulers of this world are 108 Ghost Kings; all of these Ghost Kings have strengths at the peak of God-breaking and Demon Saint realms. Above them, there is a Ghost Emperor, who is said to have devoured a large amount of the life force of living beings, finding an alternative path to breakthrough. Once completed, it might surpass this world, or even regain a physical body, with all 108 Ghost Kings under his command.

If his father were to face these Ghost Kings or even the Ghost Emperor, he would likely be left only with the struggle to flee.

"This is just basic operation, nothing worth praising," Zhang Menglong said.

"Brother Zhang, you can deal with these things, but I can't! Do you have any magical treasure for me?"

Zhang Menglong paused and glanced at Kong Lan, who was donned in a kasaya, with a string of Buddhist beads around his neck, holding a Buddha statue and a staff. If one didn't consider his looks, just his attire would present the image of an enlightened monk.

"With everything you're wearing, you still need a magical treasure?" Zhang Menglong said speechlessly, "Just with this equipment, even a Mystic-Breaking realm undead can't harm you. Do you have to exaggerate?"

"It's just to be on the safe side, ahahaha... You said I only have defense, not attack means, what if I can't help you when an emergency arises?"

"I'd already be over the moon if you didn't cause me any trouble, how could I expect you to help me?" Zhang Menglong had seen Kong Lan's panic-stricken behavior clearly earlier.

Yet Kong Lan still cast an eager gaze towards him.

"Dear brother!"

"Alright, alright! I'm afraid of you!" Zhang Menglong directly handed him a copy of the Sun Scripture. Of course, this wasn't the original version from The Mummy; it was a replica made by Gou Dan, with much less power and lacking many strong spells.

But it already contained many spells for restraining the undead. Crucially, it was translated into the common language of Haotian Continent, usable by anyone, and with Kong Lan's current Mystic Qi cultivation and physical strength, he could handle a few Heaven-breaking realm undead.

"Hahaha, thanks, brother!" With the scriptures in hand, Kong Lan immediately felt much braver, realizing that once he could attack them, these undead creatures didn't seem so terrifying.

There's indeed a saying that is very true: all fear stems from insufficient firepower; as long as the firepower is enough, it doesn't matter if it's Sadako or Kayako, they can all be brought back as wives.

Besides learning about the Ghost Kings and Ghost Emperor from those two undead warriors, they also gained some understanding of the activity ranges of human martial artists and demon beasts, and the method to return to their original world.

All 108 Ghost Kings manage their respective Ghost Cities, each having a region in the center with a black hole-like area. Undead creatures cannot pass through these passages, but any living being can use them to return to their world.

However, very few have been able to approach these passages under the surveillance of an entire Ghost City's undead, and even when they do, they're almost always spiritually damaged. The ancestor of the Rifting Sky Blue Heaven Beast Clan was a peerless expert, yet even he could only use cunning to approach the passage.

Ultimately, surrounded by countless undead, while he returned to his world, he still did not survive.

Surrounding these Ghost Cities, groups of living humans and demon beasts linger, struggling to survive under the ghosts' watchful eyes, while seeking opportunities.

Because so many wish to pursue paths of breakthrough through this world, most living humans and demon beasts here are of high realms, and new blood is continuously added, with their numbers not depleting but increasing.

Now they were heading toward a Ghost City known as Demon Eye Ghost City, ruled by a Ghost King named Demon Eye. Reportedly, in his original world, he was an extremely powerful being, with all his abilities concentrated in the third eye on his forehead.

But attempting to break through the God-breaking peak, he was ambushed and brought to this world in anger, surviving in a different form. Currently, he holds God-breaking peak strength, ranking in the top ten among the 108 Ghost Kings.

Because the Demon Eye Ghost King is very lazy, as long as their Undead Flame is not destroyed, they have endless life, leading them to take things easy. He never actively seeks out surrounding humans and demon beasts, only his subordinates occasionally hunt.

Thus, quite a few living beings have gathered around this Ghost City, some even having passed through the central passage back to their world alive before.

Since they needed to find people, Zhang Menglong and his group naturally aimed for places with living humans, to help Kong Lan further search for his father's whereabouts.

Most of the undead reside within Ghost Cities, and for three days straight, Zhang Menglong and Kong Lan didn't encounter a single undead.

By noon on the fourth day, they finally heard some unusual sounds, coming from a forest ahead, the first living aura Zhang Menglong had sensed so far.

"Let's go check it out!"

...

This was a gathering of over 200 human martial artists and more than 50 demon beasts. In such an environment, demon beasts and martial artists became incredibly united, as they shared a common enemy.

This was a small habitat for humans and demon beasts, and generally, they wouldn't stay at one place for more than a month. But with sheer bad luck, they had only been here for less than ten days when they encountered a group of undead warriors.

Against the undead, they almost had no other choice but to run immediately.

But this time, the undead group exceeded 1,000, with even undead beasts appearing, including an undead dragon over 2,000 meters long, engulfed in green flames; no one could break through such a blockade.

Under the siege of so many undead, their defensive circle grew smaller, even suffering casualties.

A human martial artist burned all his energy; this was something they discovered—when nearing death, they could attain a brief moment of 3.5-D characteristics to partially harm undead.

But the price was their life.

"You all go!" The martial artist was burning his soul, his attack repelling a few undead, granting others a sliver of hope.

"Damn!" Remaining martial artists followed closely, striving to break through the opening made by a comrade's sacrifice.

Yet, the number of undead was too large, and that martial artist wasn't of pinnacle strength; only half had escaped when his life energy depleted, falling to the ground, and the gap was sealed again.

"It's over!" The pathway opened by a comrade's life seemed to no longer matter, leaving the remaining martial artists in despair.

"Mommy bhami hum!" A golden Buddha palm descended from the sky, blasting away several weak undead.

"Who?" Several undead warriors instantly looked on guard.

Amidst Buddha's light, two figures slowly emerged,

"Zhang Tianshi here!"

"I am Kong Lan, Heavenly Venerate!"
