Chen Feng knew very well that an enemy capable of mobilizing his people to resist a Heavenly Rank Avatar warrior was definitely not one he could handle.

Just as he was about to take the opportunity to escape in another direction, the safety box inside his tactical backpack made some faint noises.

Chen Feng frowned, but did not immediately check the security box.

Instead, they quietly waited for the Celestial Avatar warriors to leave with a large number of tamed giant beasts and their people.

...

When only a few members of the Avatar clan remained in their lair, Chen Feng carefully took out the safety box containing the Crystal Devouring Beast, wanting to see what had happened.

Dull, thudding sounds echoed continuously inside the safety box.

The Crystal Devouring Beast was now more than ten times its original size, but it was still only the size of a finger.

As it writhed and twisted inside the safety box, its black scales left scratches on the alloy box walls.

There were no more giant beast spoils around it for it to absorb.

Hunger gnawed at it like a poisonous vine, gradually making this already powerful star beast more and more irritable.

Seeing the increasing number of cracks on the safety box, Chen Feng was secretly alarmed.

This specially made safety box was originally intended for transporting high-risk behemoth embryos, but no one expected that the destructive power unleashed by the Crystal Devouring Beast due to hunger would be so astonishing.

Chen Feng knew he could no longer contain the little guy.

With a soft click, the security box's unlocking mechanism was opened.

As Chen Feng lifted the top cover of the safety box, the Crystal Devouring Beast, which had been frantically ramming against the safety box, suddenly froze, its twisting body coming to an abrupt halt.

The next second, it seemed to have smelled some deadly temptation and let out a sharp screech.

Before Chen Feng could react, the Crystal Devouring Beast suddenly exerted its strength, its body shooting out of the safety box like an arrow, and using its two pairs of balanced wings on its back to fly rapidly into the nest of the Avatar tribe ahead.

Oops!!

Chen Feng immediately lay prone again, and his Eye of Prophecy scanned the Avatar tribe below, trying to find out where the Crystal Devouring Beast had fallen.

However, just a dozen seconds later, the small figure that had been so clear in Chen Feng's vision suddenly vanished from his sight!

Only a fainter and fainter afterimage remained, constantly flying around!

Chen Feng sighed.

Left with no other choice, he took out the rope from his tactical backpack and prepared to enter the Avatar tribe.

...

Chen Feng tightened his arms and, using the camouflage properties of the armor he wore on top of him, slowly landed on the corridor of the Avatar's lair.

Their nests are much more spacious inside than one might imagine, yet the light inside is pitifully scarce.

Moreover, deep within these spaces, dozens of relatively thin Avatars huddled around the stone houses; most of them were elderly people and women.

Their blue skin glowed softly in the light, but the weariness between their brows was undeniable.

The younger avatars clung tightly to the hem of their elders' clothes, their big eyes filled with unease.

Chen Feng reacted quickly and immediately hid in the deserted lair...

Unlike the tranquility deep within the lair, more than a dozen burly Avatar warriors were patrolling back and forth along the circular passage leading to the core area.

They were the tallest warriors Chen Feng had ever seen, their muscles sculpted with fluid lines, and their blue-gray skin adorned with dark red totem patterns, seemingly some kind of mark of honor.

In their hands, each held a spear crafted from the bones of a massive beast, its tip inlaid with sharp crystals.

On his back was a longbow woven from vines and animal horns, and his quiver was full of feathered arrows, the arrowheads gleaming with a dangerous light.

A leading Avatar warrior stopped, his high nose bridge trembling slightly, and his eyes looked directly at the spot where Chen Feng had just landed.

Under the half-closed gaze, the Avatar warrior's pupils contracted to a thin slit as he intently stared into the depths of the lair where Chen Feng had hidden.

Immediately afterwards, he raised his spear and gently tapped the rock wall with the tip, producing a dull "thud, thud" sound.

The patrolling soldiers immediately stopped their patrols and began looking at each other's positions...

Chen Feng was not spotted by the patrolling Avatar warriors.

However, the situation is equally far from optimistic.

Even if Chen Feng manages to find the extremely valuable Crystal Devouring Beast, he isn't entirely confident he won't be spotted by these vigilant Avatar warriors.

It's even less likely they could deal with that extremely powerful Celestial-Rank Avatar warrior!

Left with no other choice, Chen Feng took out the head-mounted display component and three reconnaissance robots from his tactical backpack.

These reconnaissance robots, called "Little Bugs," don't carry any combat weapons, but they can switch between dozens of detection modes. They can even detect the chemical agents carried by the giant beast embryos that escaped from the safety box!

However, before Chen Feng could release "

Chen Feng, however, heard a muffled thud coming from not far away, the sound seemingly carrying the dull thud of a sharp weapon piercing flesh...

Something's not right...

Chen Feng immediately released the "Little Bug" robot in his hand and observed the outside environment through the headset.

The scene on the screen immediately caused Chen Feng's pupils to shrink.

The three Avatar warriors who remained in the area also seemed to have discovered something.

Before they could even retaliate, short blades pierced their chests in an instant, and by the time the Avatars from further away arrived, their companions had already lost all their lives.

"It's a Darkborn!"

Chen Feng gave a wry smile.

Chen Feng never expected that these former enemies would take advantage of the absence of the Heavenly Rank Avatar warriors to launch a sneak attack on his tribe's lair.

However, at that moment, Chen Feng witnessed an even more unbelievable scene...

A blurry, pale red outline, almost blending into its surroundings, glided along the ground like a ghost towards the five wary Avatar warriors...

The movement of the silhouette was completely silent; wherever it passed, even the grass on the ground only swayed slightly, as if a gentle breeze had swept by.

Chen Feng's fingertips unconsciously tightened around the control lever.

Even with Chen Feng's current strength, he was unable to accurately identify the faint red outline.

The five Avatar warriors had clearly received an alert about their comrade's death and were heading to the scene to investigate, their eyes scanning their surroundings warily.

However, these experienced Avatar elites never imagined that death was silently approaching them.

The next second, a cold glint appeared!

Two silver-white blades flashed, and the enemy hidden in the void instantly struck!

The swordsmanship was so fast that even the Avatar warriors didn't have time to react; a neat line of blood instantly appeared on their necks.

"Enemy attack!"

The last Avatar warrior finally reacted, letting out an angry roar and thrusting his energy spear forcefully towards the shadowy figure.

And the shadow finally revealed its true form under the attack of the energy spear!
