Begin the fourth-tier advancement trial!

Deep into the night, the Wuyuan Mountain Range echoed with mournful roars, chilling to the bone just from the sound.

Inside the Zerg Nest.

A large number of monster corpses were transported back one after another, then converted into bio points.

These bio points, after being transformed by Little Jin, quickly turned into new Zerg units.

"Open the Zerg Nest panel."

With a thought from Chen Ming, a pale blue translucent panel instantly appeared before his eyes.

[Zerg Nest]

[Tier: Second Tier (Same as Zerg Overlord, Demon Little Jin's tier.)]

[Durability: 50e/50e points.]

[Defense: 120k points.]

[Current Stored bio points: 18.52 million points.]

[Attached Zerg Organs: Energy Storage Chamber, Egg-laying Tissue, Incubation Chamber, Gene Fusion Lab, War Fortress.]

[Unlocked Units: Demon Engineer Bug, Demon Combat Proto-bug, Demon Lava Bomb Bug, Ancient Titan God Bug, Demon Dragonfly Bug, Demon Abyss Dragon, Demon Face-Hugger Bug.]

[Unlocked Hero: Scourge Empress.]

[Current Unit Count:

Demon Engineer Bug 10 million, Combat Proto-bug 1 billion, Ancient Titan God Bug 15 million, Lava Bomb Bug 50 million, Demon Abyss Dragon 35, Demon Face-Hugger Bug 3.52 million, Demon Dragonfly Bug 1.25 million.]

[Note: Zerg unit/hero levels are the same as the Zerg Overlord's level.]

...After three days of development.

The Zerg Army not only recovered the losses from the previous encirclement of the Sinful Beast Clan but also expanded several times in scale.

The cumulative number is close to 2 billion.

Moreover, as Little Jin's level broke through above 20, the [Zerg Nest] tier also advanced to the second tier, with durability and defense greatly improved.

"At this expansion rate, it probably won't be long before the Zerg Army can break through ten billion."

Muttering softly, Chen Ming was in high spirits.

There were seven days left until the beast tide attack for the city-building mission, enough time for the Zerg Army to expand fully again.

"Little Jin!"

With a thought, Chen Ming summoned Little Jin before him.

"Master!"

Little Jin bowed respectfully.

"In the few days I'm away, you must hurry to expand the Zerg Army's scale."

"Yes, Master!"

Little Jin nodded.

As the Zerg Empress, she had absolute control over the Zerg Army.

If the Zerg were compared to a living organism.

Little Jin would be the brain of this organism, easily controlling everything,

while the Zerg Army would handle the remaining functions.

After giving a few simple instructions, Chen Ming thought for a moment and, for safety's sake, left the [Abyssal Undead Giant] behind.

Although the Zerg Army now had a preliminary scale, limited by Little Jin's level, all units were only level 28.

As his level reached 60, the [Abyssal Undead Giant] evolved again, now becoming a Legendary-Grade boss.

[Abyssal Undead Giant] (Legendary-Grade Boss)

[Level: 60 (Same as the summoner's level.)]

[Legendary-Grade Boss Template Bonus: Max HP +3e points, Physical/Magic Defense +50%, all damage taken -50%.]

[Abyssal Undead Giant Racial Bonus: Max HP +5e, recovers (level x 1000) HP per second, permanently in super armor state, immune to all control effects.]

[HP: 12e/12e points.]

[Strength: 30k points.]

[Agility: 10k points.]

[Intelligence: 6k points.]

[Stamina: 80k points.]

[Spirit: 80k points.]

[Physical Attack: 60k points.]

[Magic Attack: 12k points.]

[Physical Defense: 120k points.]

[Magic Defense: 120k points.]

[Skill One: Abyssal Stomp Lv15. (Details omitted)]

[Skill Two: War Roar Lv12. (Details omitted)]

[Skill Three: Giant King's Will Lv10: Passive Skill (Details omitted)]

[Skill Four: Frenzy Lv10 (Details omitted),]

[Skill Five: Abyssal Battle Axe Lv8 (Details omitted).]

[Skill Six: Immortal Blood (Details omitted).]

[Skill Seven: Flesh Armor Lv9.]

[Additional Attribute: Undead Sovereign (Gold).]

[Description: A powerful giant, after falling into the abyss, was corrupted by abyssal power, undergoing indescribable changes.]

...In terms of tankiness, the current [Abyssal Undead Giant] can already rival Legendary-Grade bosses above level 100.

"Abyssal Undead Giant, you are responsible for protecting Little Jin's safety."

"If anything unexpected happens, take Little Jin and leave immediately."

Chen Ming instructed.

"Yes, Master." The Abyssal Undead Giant responded dully.

Little Jin was the core of the Zerg Army; if she died, the entire Zerg Army would be wiped out.

This was why Chen Ming left the Abyssal Undead Giant behind.

Under the dual protection of the Abyssal Undead Giant and the Zerg Nest, as long as Little Jin did not actively leave the nest, even if a divine-level powerhouse arrived, she could resist briefly.

After making all these arrangements, Chen Ming took a deep breath and decisively initiated the fourth tier advancement trial.

[Note: The advancement trial can be entered as a team, but the difficulty increases with the number of participants.]

...Looking at the series of prompt options that popped up before him.

Chen Ming did not hesitate at all, decisively choosing the Abyssal Grade difficulty advancement trial.

[Ding-dong, you have initiated the Abyssal Grade advancement trial.]

[Generating the Abyssal Grade advancement trial task.]

[Generating, please wait...]

[Abyssal Grade advancement trial task generation complete, corresponding dungeon instance has been generated.]

[You can view the Abyssal Grade advancement trial information yourself. After confirmation, you will be teleported to the task dungeon instance.]

A series of prompts popped up before Chen Ming's eyes.

Chen Ming looked at the advancement trial panel.
