From Abyssal Invasion to Bursting Stars with a Single Sword-Chapter 227 - 185: Break Through Defense, Level Up_2

The ion sword light tore through the giant Abyss Worm Commander's outer armor, plowing two deep wounds into its back.

The ion sword light cauterized the wounds, emanating a burnt stench.

Seizing the opportunity, Lu Heng followed up from behind the Black Feather Spirit, dodging the poisonous mucus sprayed out, then leaped up, performing a reversed Rising Dragon Slash from the back of the Abyss Worm Commander, splitting its back in two.

At the same time, he took out an All-Nitrogen Ion Bomb and threw it into the wound on its back.

The All-Nitrogen Ion Bomb exploded with a loud "bang," causing the body of the Abyss Worm Commander to tremble violently as mucus, blood, and viscera burst out all at once.

[In battle, gained insight, Sword Technique Proficiency +1]

[Killed the Giant Abyss Worm Commander, absorbed 1000 points of Demon Energy.]

Along with the dozen or so mechanical demons he had just cleared, the absorbed energy broke through the level barrier.

[Source Energy Level increased to 27, All Attributes +3, Agility Attribute additionally +0.9]

After taking down the Giant Abyss Worm Commander and the Wing Demon Commander, the guarding forces on the third floor lab quickly collapsed.

Under the fire suppression of the mechanical units, each demon was shredded under the barrage, and each mechanical guard was shot into a sieve with debris scattered everywhere.

In just 5 minutes, the battle was near its end, all enemy targets cleaned up.

"30 seconds to clean up the battlefield; Anka, use miniature missiles to blow up the passageway we came through. We'll move to the fourth floor in 30 seconds," Lu Heng quickly arranged the action steps.

All units mobilized to start cleaning the battlefield.

Su Muyu controlled the Divine Feather Eagle, circled around the area, and collected all the Source Material and Crystal Cores.

Lin Zeyu searched among the ruins for usable mechanical modules.

However, during the battle, the fire suppression was very fierce, so most of the mechanical guards were smashed, leaving hardly any intact modules.

The passage to the fourth floor had already been sealed.

However, that wasn't a problem.

Nano self-destruct robots found the weakest spot in the passage to the fourth floor and conducted a targeted detonation.

Boom!

A loud blast created a downward hole.

Lu Heng led the team down to the underground fourth-floor passage, and following the structure they had initially seen, they broke through the mechanical guards' resistance and rushed to the door of the fourth-floor lab.

The fourth floor was a laboratory for mechanical demon research, differing from the previous floor, which was for demon body modifications.

This floor involved creating suitable mechanical modules for equipping demons.

Relatively speaking, the fourth floor had more Commander Level demons.

However, under the strong fire suppression of the team, they quickly broke through and began clearing the demons on this floor.

The mechanical units conducting fire suppression, along with Lin Zeyu's positions, were all at the back.

While conducting fire suppression, a Shadow Demon suddenly appeared from behind, extending its claws to stab at Lin Zeyu's back.

Lin Zeyu had placed Hidden Eyes along the way to keep an eye on the rear.

The moment the Shadow Demon appeared, he immediately did a forward roll to dodge the attack and yelled, "There's an invisible one!"

The moment the Shadow Demon attacked, it triggered a Black Witchcraft Immobilization Trap, and several Dark Thorns grew from the ground and walls, entangling the Shadow Demon.

The Shadow Demon immediately turned into a shadow, slipped into the ground, and broke free from the trap, continuing to chase forward.

Passing by a mechanical unit, it extended its claws from the ground and smashed a self-propelled laser beam vehicle into pieces.

Lin Zeyu turned his gun and fired two shots at the Shadow Demon with a "bang, bang," hitting the ground and creating two pits, but causing no damage to the Shadow Demon.

"This thing's like a shadow; can't hit it!"

"Shadow Demons are afraid of light; use the Shock Bomb and Divine Feather Eagle's Skill. If that doesn't work, call me," Lu Heng was advancing furiously at the front and couldn't head back temporarily.

Lin Zeyu heeded the reminder, raised his hand to shoot an Energy Hook at the ceiling, rose into the air, and then concentrated a Source Energy Shock Bomb, simultaneously shouting, "Shock Bomb explosion countdown 3, 2, 1..."

After the countdown, the Source Energy Shock Bomb energy compressed completely and was thrown at the Shadow Demon.

Boom!

The explosion of the Shock Bomb erupted.

At the moment of explosion, Lin Zeyu turned around, closed his eyes, and shielded them with the back of his hand.

Other mechanical units also activated the Shock Bomb defense mode, enduring the impact of the Source Energy Shock Bomb.

The Source Energy Shock Bomb exploded, releasing a bright light that instantly caused the Shadow Demon to scream in agony.

However, the Source Energy Shock Bomb did not kill the Shadow Demon outright.

The body of the Shadow Demon was blasted into pieces, sliding along the wall as it tried to pursue Lin Zeyu.

Right after that,

Su Muyu reminded through the communication channel, "Blazing Flame Light countdown 3, 2, 1..."

Divine Feather Eagle charged forward, unleashing all its energy, and used its innate skill "Blazing Flame Light," emitting a sun-like intense light that enveloped a 10-meter radius and inflicted high-temperature damage of 1200 degrees at the center.

Under the intense high-temperature light, the Shadow Demon struggled and screamed, eventually being burnt to ashes.

After dealing with the Shadow Demon, Lin Zeyu saw a data prompt that he had absorbed 600 points of Demon Energy, and his level had been raised to 26.

Lu Heng cut down two Commander Level Demons ahead, then swept through the remaining low-level demons and mechanical guards with firepower.

The battle was resolved in a total of eight minutes.

"Clean up the battlefield, we are moving to the next floor immediately, Anka, destroy the entrance passage."

After giving the order, Lu Heng then commanded the nano self-destruct robots to find a way down.

The fourth floor was cleared, next was the fifth floor.

During reconnaissance, Lu Heng had not seen the interior of the fifth floor because the defense level was too high, featuring wall-to-wall laser matrices that would turn anyone who dared approach into ash.

...

After cleaning up the battlefield and collecting all the Source Material and Crystal Cores.

The team reached the entrance to the fifth floor.

The nano self-destruct robots detonated directionally, blasting a gap, but there were not enough robots remaining, and the walls of the fifth floor were thicker than the previous ones, so only a fist-sized hole was created.

Such a small hole was too small for a person to pass through.

And below that, the corridor was filled with laser matrices.

Just sticking one's head out would result in being attacked by hundreds of laser beams.

Lu Heng picked up a metal sheet and threw it into the hole.

As the metal sheet fell into the corridor, before even touching the ground, it was struck by hundreds of laser beams and instantly melted into molten iron, dripping onto the floor.

Looking inside through the Hidden Eye, Lin Zeyu said, "This is too intense; it turns to molten iron instantly. If it were a person, they'd be cooked in a millisecond."

Beforehand, Lu Heng had discussed a plan with Ze Wei'er Matrix.

However, Ze Wei'er Matrix indicated that they needed to see the arrangement of the laser matrix to find a solution.

Lu Heng promptly asked, "Professor Ze Wei'er, have you found a breakthrough method?"

From atop a mechanical unit, a holographic screen popped up and responded, "This is indeed the highest level laser defense matrix from the Sikes Military. It is difficult to break through from the front.

"The strategy I can provide is to cut off the energy supply, then deplete the laser matrix's battery energy, and finally destroy the laser matrix.

"However, once the energy supply line is cut, the system will activate a backup line, which roughly takes about 30 seconds.

"The laser matrix's battery energy can maintain its attack for about 20 seconds.

"This means you must deplete the laser matrix's energy within 30 seconds, then use the remaining 10 seconds to destroy it."

After hearing this, Lu Heng found the challenge rather daunting.

However, having reached this point, they could only proceed.

Lu Heng then asked, "What's the situation outside?"

Ze Wei'er Matrix replied, "The first reinforcement arrived ten minutes ago and has started intercepting. Only a few unmanned drones have entered the base interior, so they should not pose a threat to you.

"However, the control network I am managing has noticed that the second batch of reinforcements will arrive in fifteen minutes, including a team of Human Superpower Users.

"With the current firepower of the mechanical units, it is not possible to stop this team of Superpower Users."
