Soon, the old man and the scarred man were captured. The massive Dragoon-type mechanical soldier 4th generation ignored all their attacks, pressed down on their heads, and just like they had treated Lu Yuan on the road, sent the two men to the zombie face that only had eyes, nose, and mouth like Lu Yuan's.

"Grab that Taoist priest, and we'll spare your lives!"

As Lu Yuan spoke, his bony fingers pierced their bodies, and like the sorceress, black tendons quickly covered half of their bodies.

The old man bent over in pain, while the scarred man only shed a few drops of sweat and showed no further change.

A hint of surprise flashed in Lu Yuan's eyes. He took out a mechanical device, from which a palm-sized metal drill bit emerged, piercing out two long spikes, which he then slammed into the scarred man's chest.

In just a few moments, the muscles in his chest seemed to be under some kind of control, burrowing into the scarred man's flesh like living snakes, making his body grow even larger.

Before long, the scarred man underwent another change. He grew a head taller out of thin air, and his thick muscles burst out, tearing his clothes.

"This is..."

The sorceress and the old man looked on in surprise, their eyes darting wildly over the mechanical device on the scarred man's chest.

Lu Yuan said, half-jokingly, "Human-demon blood can extend one's lifespan by 50 years."

50 years?

“Catch that Taoist priest, and these are yours.” Lu Yuan took out two new mechanical devices, carefully propelled the spikes in front of the two men, and then put them back: “If you fail to catch him, the demonic blood will enter your brains, and you won’t even have a chance to be reincarnated.”

I need him!

The old man was filled with doubt and suspicion, but he couldn't wait to speak, and suddenly pointed at the scarred man.

"Okay!" Lu Yuan agreed. The scarred man, who had just been smug, immediately looked miserable. He knew that the old man definitely had no good intentions.

The old man gave the sorceress a wink, and the two of them went over together, circling around the man.

Before long, the sorceress drew many strange symbols on the scarred man's body, while the old man simply put seven or eight black and red dots on the scarred man's body.

Fifty years may not be a lie. The extension of the virus's lifespan and the extension of the world's lifespan are definitely two different things, but the changes in front of us are nothing to worry about, so we are naturally not afraid of their inspection.

The only thing Lu Yuan didn't know was whether this increase in lifespan would lead to people coming from the underworld.

When the sorceress stopped, the old man nodded happily and, in cooperation, pressed a drop of cinnabar onto the scarred man's head.

"Looking up at the blue sky, my master is by my side, supporting his disciple. With skin of copper and bones of iron, I have become as strong as Mount Tai. I wear twelve iron hats and twelve layers of iron armor. My skin is wrapped in copper three times and iron three times!"

"With divine protection, you are immune to all evil. Go!"

The sorceress pinched out a handful of ashes and quickly threw them at the man. In the blink of an eye, the man's eyes darted around a few times, and he uncontrollably opened his arms and rushed towards the corpse demon standing at the entrance of the underground palace.

Lu Yuan smiled, and the robots around him immediately rushed over.

Five robotic police officers, seven dragoons, and Lu Yuan, who was accompanied by the sorceress and the old man, all went inside together.

boom!

The man's figure disappeared into the darkness of the underground palace. A few breaths later, the earth trembled in the stillness, and waves of sound spread out in all directions.

"roar!!"

The furious roars of the Corpse Demons echoed throughout the underground palace, and an almost destructive desire spread from their voices, shattering the tranquility of the world.

Just then, the prototype of the biological virus appeared at the entrance of the underground palace, and in response to the roar that shattered the peace of the world, it emitted an even more terrifying mental fluctuation.

Although zombies are intolerable to heaven and earth, demonic thoughts are a new life.

However, the virus on Lu Yuan's body is one that can destroy the life force of the entire world. Now, under Lu Yuan's control, it has actually destroyed a mission world. In comparison, Lu Yuan's spiritual world here is comparable to a great demon.

In an instant, the spirit of the underground palace corpse demon retreated, and its roar, which had failed to intimidate the enemy, vanished in an instant. It was forced back inside by Lu Yuan's subordinates.

Immediately afterwards, countless ghosts rushed out from behind the demon corpse.

"The evil spirit in the underground palace: born of Yin and born of Yang, it brings disaster with the Yang Blade. When a living person enters the coffin, it bursts out with evil energy."

I don't know who built this underground palace. The corpse demons in front were already rare in the human world, and the fierce spirits that have appeared now are even rarer, appearing only once every thousand years. But here, more than a dozen of them have appeared in a neat row.

As for what was inside, Lin Feng and Si Zang only glanced at it and didn't dare to go any closer.

The only information was deduced from external signs that the so-called Twelve Yin Sha entered the fate chart. What kind of murderous god and butcher would be buried in such an ominous place after his death? Could it be his enemy?

"This guy..."

As Si Zang watched Lu Yuan gradually reveal his strength, he abruptly stopped his frantic finger-tapping and said in a very low voice, "I'm afraid we can't stop him..."

After saying that, Si Zang put down the screen and waited for Lin Feng, who was sitting cross-legged, to open his eyes. He then tentatively asked, "How was it?"

A dense aura of yin energy emanated from behind Lin Feng as he slowly opened his mouth: "It's possible... but you only have one chance."

"Once? Hehe, once is fine, otherwise I really want to leave this world." Si Zang's eyes darted around, he chuckled, and leaned closer to ask, "And then...did you discover anything?"

Seeing Si Zang's expectant gaze, Lin Feng asked in confusion, "Huh?"

"It's about looking at it from your perspective, yes, from your own perspective, whether there's anything in this thing~" Si Zang leaned closer and drew a large circle in his hand, hinting at the surrounding underground palace.

"No... I wouldn't dare." Lin Feng glanced at him, then turned his head away. Even if he had discovered something, he wouldn't dare do anything. "Let's go, let's go greet him."

Inside the underground palace, the Corpse Demon surrounded the Mechanical Special Police; the Fiendish Soul trapped T3010; the Dragon Rider swept away a group of jumping zombies; the Scarface Man destroyed several Yin Souls with the power of the Divine Strike, and led the Witch and the Old Man into the depths of the underground palace.

The alienated Lu Yuan followed behind, gazing at the deepest hall from afar, without approaching any further.

In Lin Feng's surveillance, besides what was in front of him, the prototype biological virus was standing in the rear, while the earliest exposed Project Source had disappeared outside Dafang Village without a trace.

Thus, this underground palace, which was extremely dangerous to them, was effectively suppressed by Lu Yuan alone.

Tap tap tap, Lu Yuan detected the faint footsteps. In just a second, the mutated Lu Yuan saw the figure slowly emerging from the darkness.

"They're here."

After subtly reminding the three people beside him, the old man keenly spotted his target: Shizang!

"superior!"

The sorceress danced in her hands, and the scarred man's body flew into the air and crashed into them.

Seeing the approaching enemy, Si Zang flicked his sleeves and took out his golden hammer: "Wow, that's awesome?"

The hammer crackled with lightning, spun a few times, and then slammed viciously into the machine on the scarred man's chest.

Bang!

The scarred man looked down and chuckled, "Hehe, it hurts a little."

Having taken a blow and absorbed bursts of lightning, the enormous body crouched down, its hands reaching out unharmed to grab the Ongold Hammer.

Si Zang raised an eyebrow, loosened his grip, and the hammer immediately sank. A heavy force suddenly arose, causing the Weng Jin Hammer to slip from the scarred man's hand and quickly return to his own.

"Heh, though this old woman's eyes are clouded, I've long been on guard against you righteous thunder magicians." The sorceress behind the scarred man waved her arms, holding up a mask of a hairy demon god, shaking it as she laughed, "Heaven is in turmoil, earth is in turmoil, today the Thunder God is drunk, striking randomly, striking randomly!"

Si Zang suddenly felt a chill run down his spine. The electric current that had just dissipated was gathering from behind the scarred man, flying towards his feet like electric snakes.
