Cave Refuge

Zachary first decomposed the collected Merfolk blood in the Cave and, after confirming that its effect on enhancing the Cave was minimal, he realized that the Merfolk were not the target of his search after obtaining the same results from the deceased Merfolk.

The decomposing ability in the Cave only worked on dead matter and could not decompose living organisms, but it could directly decompose undead creatures. Although Zachary did not understand the principle behind this, it did not affect his normal use of the Cave.

As for the Merfolk whose arms Zachary had severed, after bringing them into the Cave and seeing no reaction, it indicated that the upgrade requirements for the Cave were not related to the number of species living within it.

Moreover, since Zachary had no inclination to collect biological species, he sent the rest of the Merfolk, including the one whose body was intact, directly to the Realm of the Undead.

After all, having brought those Fishmen into the Cave, letting them go was definitely not an option, but Zachary was also unwilling to keep the Merfolk in the Cave. Thus, sending them to the Realm of the Undead was actually the best choice.

After dealing with the Merfolk in the Cave, Zachary immediately left the Cave. Since he had confirmed that the Merfolk living in the Underwater City were not his target, Zachary decisively took out the Three Flags.

After such a long period of cultivation, the quality of the Three Flags had reached the level of Supreme Magical Treasure. With just a bit more cultivation, upgrading them to the level of Spiritual Treasure was almost a sure thing.

And the Underwater City in front of him was the best resource for upgrading the level of the Magical Weapons.

After the White Bone Puppet appeared, its huge body was immediately spotted by the Merfolk in the Underwater City. After all, such a large object appearing on the outskirts of the city would be hard to miss.

As the White Bone Puppet continued to approach the Underwater City, dozens of Merfolk emerged from the city, apparently trying to prevent the White Bone Puppet from entering.

However, the Water System Magic they were using at that time did not cause much damage to the White Bone Puppet, so even though it was attacked by various Water System Magic, the White Bone Puppet continued to move towards the city unhurriedly.

While all the Merfolk's attention was on the White Bone Puppet, they did not notice that, unbeknownst to them, many red fluids had mysteriously appeared around the city. These fluids did not enter the city but merely circled the ground surrounding it.

Since these fluids only appeared on the seafloor, the Merfolk in the city did not notice them, as they generally did not walk on the ground while coming and going from the Underwater City, but swam forward instead.

When the White Bone Puppet entered the Underwater City and began to continuously destroy the buildings, a group of very well-equipped Merfolk joined the battle.

With the addition of this group of elite-looking Merfolk, the Water System Magic, which previously had no effect on the White Bone Puppet, was now able to barely restrict its movements, although only for a mere one to two seconds at a time, which was still much better than it ignoring them completely as before.

While all the Merfolk focused their attention on the White Bone Puppet wreaking havoc in the city, the blood-red liquid on the seafloor had successfully encircled the city and then, emitting a faint glow, enclosed the Underwater City in a sealed space.

Because the area of the Underwater City was quite large, it would have been very difficult to enclose the city with Tainted Blood from the Blood Sea if it were not located under the water.

Since it was an Underwater City inhabited by Merfolk, there were naturally women, children, and elderly among the Merfolk. The Merfolk fighting ferociously against the White Bone Puppet upon its entry were doing so to protect their fellow species.

However, what the fighting Merfolk did not know was that, while they were battling the White Bone Puppet, the Resentful Spirits from the Hundred Ghosts Banner were also relentlessly reaping the lives of the Merfolk participants in the city.

Regardless of the intense battle between the Merfolk and the White Bone Puppet at the city's center, the actual casualties were minimal.

The White Bone Puppet, although large and poorly agile, especially in the highly resistant water, struggled to kill the agile Merfolk.

However, facing the White Bone Puppet, which was huge and defensively strong, the Merfolk also lacked effective means to handle it. Although the White Bone Puppet's attacks rarely hit them,

each attack from the White Bone Puppet caused significant damage to the surrounding buildings, hence the Merfolk were very anxious at that moment, desperately thinking of ways to drive the White Bone Puppet out of the Underwater City.

What they did not know was that, although there were not many casualties during their battle with the White Bone Puppet, the Merfolk hidden in other parts of the city were suffering a massacre by the Resentful Spirits.

The only method of attack by the Resentful Spirits in the Hundred Ghosts Banner at that time was to directly damage the targets' souls. This type of attack, which is soul damage, can only be resisted by using Spells.

Besides directly attacking souls, the Resentful Spirits could also penetrate ordinary buildings and had a strong sensory ability for living organisms around them.
