My Ultimate Sign-in System Made Me Invincible

This was going to be Liam's third official battle and his first since fighting Xuan Zhi and Fang Cheng almost two weeks ago.

He smiled to himself as the orc's club came down in a blur of motion. The swing split the air apart with enough force to make an ordinary man freeze in terror and lose

control.

Behind Liam, the tank shouted hoarsely, "Are you insane? Dodge!"

But Liam didn't even glance back. He didn't feel danger from the orc's attack. If anything at all, he felt curiosity.

He waited until the last possible instant—then moved.

To the adventurers watching, it looked as if he simply vanished. One moment he stood there, the next he wasn't.

The club smashed into empty air, cracking the ground where he had been standing. A gust of dust and hot wind followed the impact.

The orc blinked stupidly, confused, its crimson eyes darting left and right.

Then, behind it, in a flash of clean, precise and surgical motion, Liam appeared at its back, the borrowed sword glinting in his hand and he slashed once.

The blade met flesh and tendon, cutting through the creature's ankle as easily as slicing through water.

The orc's roar shook the clearing. Its massive frame lurched, collapsing to one knee as its leg gave out. Before it could react, Liam was already gone again.

With another blur, he slashed again and the second ankle snapped like a rope under tension.

The orc's body buckled. It crashed to the ground with a thunderous thud, shaking the forest floor. The earth caved slightly under its weight.

Its claws clawed at the ground, trying to rise but it couldn't. Its tendons were gone; its strength useless.

Liam stepped back lightly, his expression calm, almost detached.

The second orc bellowed in rage at its comrade's state. Its huge frame charged, axe raised. The wind split from the force of its swing.

Liam didn't move until the very last moment again. Then he vanished in a silent flash.

The creature blinked, disoriented—and pain erupted from both its knees. Its bones shattered under the precision of two quick slashes.

It crashed forward with a deafening roar, both legs bending at impossible angles. The ground shook.

Liam reappeared before it, his sword now slick with dark green blood.

The orc tried to swing its axe anyway, roaring defiantly. Its arm flexed, but before the weapon could move, Liam flicked two fingers.

Invisible force struck the axe like a hammer blow. It flew from the creature's grip, spinning away to embed itself deep in a tree trunk dozens of meters away.

The orc screamed in fury and humiliation. The sound grated like thunder through metal. Liam's expression hardened, annoyance flickering in his eyes.

He stepped forward and kicked. There was a deep, dull crack as his leg connected with the orc's face. The creature's massive head snapped backward, its roar cutting off abruptly. Its body went limp, crashing to the ground.

Liam studied it for a second. There was no movement or even the faintest sign of breathing.

"Dead," he said softly, though there was no satisfaction in his voice.

He hadn't intended to kill it. He was genuinely curious about orcs—creatures that existed in fiction back on Earth. He had wanted to take them back to the secret realm he got and study them alive. But he would have to make do with just one.

With a faint sigh, he turned his attention back to the fallen group of adventurers.

They were still frozen in place, their faces pale, eyes wide. The battle that had nearly cost them their lives was over in seconds.

The five of them had struggled desperately against one orc, barely holding their ground when the second appeared. Yet this man—this stranger dressed casually, without armor or visible weaponry—had appeared from nowhere and crushed both orcs effortlessly and almost lazily.

And what unsettled them most was how silent it had been. This person in front of them who was dressed so casually like he was just taking a stroll, randomly appeared out of nowhere and decimated the two orcs singlehandedly.

Not only had he defeated them, but the fact that he did so without killing spoke volumes about his control and skill.

The tank was the first to move. He staggered upright, blood staining his sleeve where his arm hung at an awkward angle. He pressed his good hand against his chest and bowed slightly, grimacing in pain.

"Thank you. If not for you, we'd all be dead," he said, with strained voice.

Liam simply nodded. He looked at the shattered shield lying near the man's feet, and asked, "Why were you fighting orcs if you knew you weren't ready?"

While Liam could had just simply asked them for his current location, he decided not to do that.

The tank winced, lowering his head. "We miscalculated. We thought it would be best if we start clearing D-Rank gates, now that he," paused and looked at the broken damage dealer, "he's close to C-Rank. And we never expected orcs to appear. "

"I guess you were taken by surprise," Liam muttered.

The man nodded. "We underestimated them. We paid for it."

"There are more of them, aren't there?" Liam asked.

The tank hesitated, then nodded. "At least five. Maybe seven."

"Then stay here," Liam said, as his gaze drifted to the treeline where the second orc had come from.

Before any of them could speak, he rose into the air.

The healer, the girl with silver hair, stared up in disbelief as he vanished into the canopy.

Within moments, distant roars echoed—then silence.

Less than a minute later, Liam returned, landing softly near the group. Not a drop of blood touched him.

He turned to the first orc that was bleeding profusely from its torn ankles, barely alive at this point.

Liam sighed softly and sent the sword in his hand flying towards it. The sword embedded itself into the orc's head, and the creature twitched before finally going still.

Using his knowledge from novels he had read, he figured that the only way for them to leave the gate was to kill all the monsters occupying it.

There was actually something Liam was curious about, and it was about how accurate some of the knowledge from his world are on these fictional worlds. He wonder if it's something the system has answers to.

The group was staring at Liam in a mix of shock and disbelief. The fire mage whispered under his breath, "All clear… in sixty seconds?"

The tank swallowed hard. "You… killed them all?"

Liam didn't reply directly, as he looked around.

"The gate exit should appear soon," he muttered.

As if responding to his words, light rippled across the clearing. A circular portal of green light shimmered into existence behind them.

The adventurers froze when they saw this. They had been doubting Liam but the appearance of the portal was confirmation enough for them.

"Go. Get them treated," Liam said.

The healer nodded quickly. She helped the mage with the broken arm to his feet. The others limped or leaned on one another, moving toward the light.

Liam stood a short distance away, arms crossed, watching them vanish one by one into the swirling glow.

When the last of them disappeared, he exhaled softly and turned his gaze to the portal.

He wondered for a moment what would happen if he set an access point here—inside a gate. But he didn't dwell on it. He had other things to do.

He had no idea how long he had been gone from Earth because he didn't take his Lucid with him. And tomorrow—both his meeting with the Crown Prince of Abu Dhabi and Lucid's public release—were scheduled.

He sighed softly and stepped through the portal.

Light enveloped him for an instant. When it faded, he was standing in an open space under clear skies.

The atmosphere here was calmer. There was a small crowd of people gathered close to the gate. They were shouting to anyone who cared to listen, trying to recruit people into their team for their gate raid.

So this is the outside world.

Liam scanned his surroundings quietly. He could see lots of tall modern buildings ahead. From this little information, he guessed that the world was a modern world just like his, but with the difference of mana, hunters or players, and monsters.

He passed through the crowd quietly. Ahead, two guards in black uniforms stood near the exit, scanning the ID cards of those that wants to enter the gate.

Liam and the group walked past them casually.

"I'm sure you guys can take care of yourself from here," he said, once they were outside the perimeter.

"Thank you once again, mister. We owe you our lives. I know we can't do much but if you ever need help, please come to the Flaming Tiger Guild. We will do our best to help," the tank said.

"I will. Go get yourself and your teammates taken care," Liam said, before walking away.

The group watched him leave with tons of questions in their heart.

Liam turned toward a quiet alley between two buildings and stepped into the shadow. He paused and made sure that he was being followed before, he assigned an access point.

After he had done that, he vanished, appearing in his master suite back ok Earth. He checked the time and he saw that barely a few minutes had passed. He smiled and snuggled into his bed, closing his eyes and drifting off to sleep a few seconds later.
