Full health is the kill threshold, no matter if you're a god or a demon!

Liu Nian's eyes lit up.

This thing is perfect for signing the Demon King Jellyfish.

So I immediately and without hesitation took one.

The shopping went quite smoothly, and Liu Nian wasn't in the mood to stay any longer. He didn't have any plans to make a move against the fishmen for the time being, since this wasn't their region.

To put it bluntly, whether it's the Abe Bees or the already subjugated trolls, even if they conquer the Murlocs' capital city, it's pointless. In fact, because they are a servant race, Tide City would be downgraded from a capital city to an ordinary city, which would be a complete waste...

Sora and Serana personally went out of the city to see them off.

"This is a token of our mermaid clan," Serana said, handing Liu Nian a pearl. "With this token, you will become a friend of the mermaid clan. You can seek help from mermaid forces in any sea you encounter."

[Mermaid Friend Badge (Mythical)]

[Effect: Once placed in your inventory, this effect will grant all mermaid faction units an initial affinity bonus of 5000 to you, and you will enjoy a 5% discount on trades in the mermaid city.]

[Description: A token of friendship personally given by the mermaid princess Serana.]

After saying goodbye to Sora, Liu Nian led the bee people away from Tide City.

Once out of the fishman's sight, Liu Nian immediately put away the Giant and returned to town.

Upon returning to the floating city, the first step was to have the giant vomit out the shark-like fishmen inside its belly, and then have the spider-like elves escort it to the Hall of Slavery for slave consciousness conversion.

Then we let the bees out for some fresh air and a bite to eat. The first day of this upgrade battle was quite busy.

The demon jellyfish inside the giant's body had long been on the verge of death from the stomach acid, and was on the verge of being killed at any moment. Now, released again, it readily agreed to sign a demon servant contract without any resistance, thus Liu Nian obtained his second demon servant:

[The Demon Servant Contract has been successfully signed!]

You have acquired a new demon servant: (Unnamed)

[Level: 99]

[Quality: Myth]

[Race: Demon King Jellyfish]

[Status: Weak]

[HP: 599 million]

Core Competencies:

1. Global Surveillance: Disperse and integrate bodily awareness into all water bodies within a radius of one kilometer to gain comprehensive perception and surveillance capabilities within that area.

2. Colloidal Cage: Liquefies itself, forming a giant biological cage. Reduces the mobility of all enemies within range by 99% and deals true damage equal to 1% of maximum health per second.

3. Mimic Tentacles: Randomly generate tentacles composed of high-density water elements, with no upper limit on the number (supported by magic power). Tentacles can carry various effects such as nerve paralysis, magic drain, life corrosion, and poison invasion.

4. Elemental Water Body: Can transform into a liquid form, immune to all types of damage except fire and ice.

5. Water Element Control: Can manipulate water within a 500-meter radius, creating effects such as water arrows, whirlpools, water prisons, and healing water.

[Description: An ancient water elemental life form born in the deep sea.]

Liu Nian only realized that the Demon King Jellyfish was afraid of ice after seeing its interface.

Come to think of it, once it freezes into ice, it is indeed easy to die.

Because the Demon King Jellyfish usually appears to have a slightly ocean-blue hue, Liu Nian immediately named it:

"I'll call you 'Little Blue'."

He then shook his head: "Hmm, that's easy to misunderstand. I'll just call you Little Blue."

Then Liu Nian took out ten snake lizard summoning rune stones and used them all without hesitation.

The space distorted slightly, accompanied by a low hiss and a heavy thud as ten enormous creatures, each over thirty meters tall, appeared.

Five-headed lizard.

Their bodies were covered with thick, dark blue scales that gleamed with a metallic sheen. Five heads, each resembling a giant python, branched out from their thick necks and were different colors—green, purple, white, red, and blue—corresponding to different elemental powers.

The bee-man guards in the square all retreated a distance. Although they knew that these were friendly forces summoned by the city lord, the natural pressure from the high-level war behemoth still made them wary.

"This is really good stuff." Liu Nian walked excitedly to the nearest snake lizard, patted its huge, pillar-like foot, and felt its cold, hard scales.

This thing will reside permanently inside the giant, which is equivalent to carrying a living siege weapon with you!

Liu Nian brought up the detailed panel and carefully browsed the attributes:

[War Beast: Five-Headed Hydra Lizard]

[HP: 568.88 million]

[Core Abilities: Five Elements Breath Control, Collective Intelligence Collaboration, Immortal Regeneration, Rock-Solid Body...]

By examining the panel count, Liu Nian discovered that this thing was even better than he had expected!

This five-headed lizard is far superior to the three-headed one!

Not only can the five heads shoot out five different types of magic arrows, but they can also mix magic. Furthermore, each of the five heads is intelligent, making them equivalent to five magicians. In other words, this thing can cast "war skills" on its own that would normally require the combined efforts of five sorcerers.

Furthermore, it possesses an extraordinary regenerative ability; even if four heads are cut off, it can be reborn as long as one head remains!

These ten guys are ten mobile, regenerative, and coordinated super magic turrets, a powerful weapon against enemy strong defenses or large units.

It was extremely useful during the promotion war.

---------------

Liu Nian took a nap and felt much better.

After waking up, he first checked various messages. After all, he now had so many subordinates and his business was quite large, so many people sent him various messages every day.

After a quick look, he found that everything was alright for the time being, and there was nothing he needed to deal with urgently, so he went to a room on the second floor that had been sealed and reinforced.

Arachne's enormous spider form was lying beside a massive portal whose framework had just been constructed, its runes flickering erratically. Her eight appendages deftly manipulated dozens of arcane threads, fine-tuning the portal's structure.

"How is the situation?" Liu Nian asked as he approached.

Arachne didn't turn around, his compound eyes gleaming: "Master, the basic infrastructure is complete, but we've encountered a technical problem: the magic in the Abyss is rich in strong 'corrosive' and 'chaotic' properties. The stable runes of the conventional spatial channels wear out too quickly under continuous operation, requiring a complete overhaul approximately every three teleportations. This is too inefficient and poses a safety hazard. There must be a problem with some of my setup; after all, there were far more than three teleportations..."

Is there a solution?

"Yes." Arachne finally stopped what she was doing, turned her upper body, and said, "We need a spatial conduction medium with extremely strong magical inertia and the ability to self-repair as the rune substrate. I searched the floating city's database and inventory, but there were no materials that met the requirements. However, the Silverscale Naga race has long lived in the high-pressure and magically chaotic areas of the deep sea, and their 'shed scales,' after special refining, are one of the best known spatial stabilizing materials."

"Alright, I'll leave this matter entirely to you." Liu Nian nodded in agreement. The troll resources left behind in the Demon Abyss were an important supplement to his plan, and the portal had to be opened no matter what.
