Lu Heng felt Su Muyu's back receive a fierce blow, and both of them were thrown out.
But nothing was visible in their line of sight.
Lu Heng's gaze sharpened as he embraced Su Muyu and rolled on the ground twice. "How are you?"
Su Muyu's back was in pain, but she clenched her teeth and forced out two words, "Invis... invisibility..."
Lu Heng hadn't seen anything rush at them, but Su Muyu had definitely been attacked.
Without her reminder, he had already guessed that an invisible demon had appeared.
However, looking around, he couldn't see it anywhere. He could only hold the iron sword in front of him and stay alert.
"It's coming..."
Enduring the intense pain in her back, Su Muyu pointed towards the left.
Lu Heng raised his sword to block to the left. With a "clang," he retreated half a step, immediately adjusted his stance, and swung his sword in a counterattack.
But his sword only sliced through the air, hitting nothing.
Invisible monsters were one of the most dangerous beings at the beginning of an Abyss Descent.
Because when superpower users are at a low level, they basically don't have the ability to detect invisibility, and encountering one usually means certain death.
Fortunately, Su Muyu had now learned the skill of detecting invisibility and could detect the creature in advance.
Lu Heng blocked the second attack of the invisible demon and noticed that this creature's intelligence was very high.
Because its second attack wasn't aimed at him, but at Su Muyu.
Once Su Muyu died, leaving them without the ability to detect invisibility, there would be absolutely no way to deal with this creature.
Thus, Lu Heng always stayed by Su Muyu's side, not daring to leave her for even a step.
"How are you? Are your injuries severe?" Lu Heng quickly turned to look at her, noticing the large beads of sweat forming on her forehead.
Su Muyu waved her hand, lacking the strength to speak. She clenched her teeth and directed the scout eagle to dive down.
The scout eagle descended to two meters above the ground, then maintained that altitude and started to circle the area.
Lu Heng immediately understood, Su Muyu was using the scout eagle to pinpoint the invisible demon's location.
Relying merely on pointing with fingers would only tell the approximate direction of the invisible demon, not the distance, making it hard to initiate an attack.
However, using the scout eagle as a marker to lock onto the position of the invisible demon made things much simpler.
Lu Heng glanced back at Su Muyu, seeing large beads of sweat rolling down her forehead. He knew she couldn't hold out much longer and must end the battle quickly.
"Hold on a little longer, I'm going to finish it off soon."
Since the invisible demon relied on its invisibility, its physical attributes and strength wouldn't be very high.
Lu Heng held his sword horizontally and activated "Thunder Weapon." Streaks of thunder rose up along the blade, then he charged towards the position of the scout eagle.
The scout eagle started darting left and right, appearing to dodge Lu Heng's charge.
Clearly, it wasn't the scout eagle trying to dodge, but the invisible demon.
A fierce gleam flashed in Lu Heng's eyes as he approached the scout eagle and executed a "Zhenyue Style" chop.
Clang!
A powerful and heavy chop struck down, the sword blade penetrating something.
Thunder roared out, rampaging across the body of the object.
Amidst the blue electric currents, the form of a demon gradually became visible.
It was indeed an invisible horned demon.
Howl!
The invisible horned demon let out a mournful shriek and raised its sharp claws to counterattack.
But having lost its invisibility, it was no longer a threat to Lu Heng.
Lu Heng dodged the claw strikes, smoothly withdrew his iron sword, and swung again, slicing it into two.
[Killed the Invisible Horned Demon, absorbed 40 points of Demon Energy.]
[Demon Energy strengthened energy level, Source Energy Level increased to Level 4, All Attributes +1, Agility Attribute additionally +0.3]
The Invisible Horned Demon turned to ashes amongst the thunder and flames, and the remaining energy condensed into a Demon Crystal Core.
Judging by the concentration of color, it was no ordinary Demon Crystal Core.
Lu Heng picked it up to check its attributes.
[Invisibility Veil Crystal Core: Absorbs the energy of the Crystal Core with a chance to learn the "Invisibility Veil" skill.]
[Invisibility Veil: Releases energy that covers objects, making them optically invisible. Skill consumption: 3 Source Energy points/minute. Skill level: D.]
...
Today was a lucky day, with another Skill Crystal Core appearing.
Moreover, among the many invisibility skills, the "Invisibility Veil" was one of the most practical.
However, there was no time to study this skill now because Su Muyu was seriously injured.
Lu Heng quickly picked her up and left the area.
"Is my back broken? Am I going to be in a wheelchair forever..." The impact that Su Muyu had blocked for Lu Heng had hit her spine, and she was already in excruciating pain.
She suspected her spine might be broken, which would mean paralysis of the lower body.
Hearing her words made Lu Heng's heart sink.
Could he really not change her fate of being wheelchair-bound for the rest of her life despite saving her once?
"No! Try moving your toes." Lu Heng's tone was a bit tense.
Following his instructions, Su Muyu tried to move her toes and responded, "It seems like I still can."
"Then it's fine, if the toes can move, it means the spinal nerves aren't damaged." Lu Heng let out a sigh of relief, and entered a shop that looked like a pharmacy in the foggy city to look for medication for external injuries.
Lu Heng set her on a chair and let her lean forward to inspect the injury on her back.
Her anti-stab vest had been torn open, showing the severity of the impact.
If it weren't for the vest, her back might have been pierced.
Lu Heng took off her anti-stab vest and saw that her back clothing was stained red with a large patch of blood. Upon lifting the clothes, he finally saw the wound.
It was a deep but not overly large wound caused by the impact of the Horned Demon's horn, and blood was still seeping out.
Checking the wound, Lu Heng said, "It hasn't reached the bone; I will help you stop the bleeding first."
As Lu Heng applied the medicine, Su Muyu trembled from the pain, her fists clenched tight, trying not to cry out.
She didn't forget to release a scouting eagle to keep watch, worried about any dangerous creatures that might be nearby.
After all, the smell of blood could attract bloodthirsty beasts.
Lu Heng efficiently bandaged her wound with a gauze and then helped her up.
...
After stopping the bleeding, Su Muyu gradually recovered, looking less pale.
A gargoyle had just been killed nearby, and the smell of blood might attract even more terrible creatures.
So, Lu Heng carried her on his back and continued on their way.
As the sky grew darker and Su Muyu, weakened from her injury, lay limp on Lu Heng's back.
Nonetheless, she still controlled the scouting eagle, sending it high into the air to scout and try to understand the layout of the city.
"It's getting dark, we need to find a place to rest, and if we could find the castle from the challenge task, that would be great. I think the castle might shield us from spiritual pollution." As Lu Heng spoke, another warning of spiritual pollution appeared, reducing his spiritual power by 1 point.
Su Muyu had already been looking for a suitable place to rest.
She knew well how dangerous it was to be injured in such an environment.
Not wanting to become a burden, they needed to find a shelter where they could hide from the demons.
Soon, using Summoned Creature Vision, she spotted a strange terrain formation in the sky.
The terrain was circular with a depressed center and raised surroundings, and it looked less like it was man-made and more like it had been formed by a huge meteorite.
Controlling the scouting eagle, she flew closer, and under the Detecting Invisibility skill, she finally spotted a castle barely visible in the crater.
"I... I think I found the castle," said Su Muyu excitedly.
Lu Heng's eyes lit up, and he quickened his pace in the direction she was pointing.
