Walking over the cliff and standing at the other end of the metal bridge, the chief commander looked back at Wu Tie in surprise.

"I'm so curious, actually, I only saved you on a spur of the moment, I really didn't think you could really accompany me. ”

His right hand patted his left arm vigorously, and the chief commander smiled: "Do you remember my arm? I thought you would hesitate and be scared at such a young age. ”

Wu Tie looked at the newly grown left arm of the Chief Commander.

"There was a lot of hesitation...... Fear, to be honest, there are also. The white tiger cracked across his shoulder, and Wu Tie rubbed the barrel of the gun hard: "However, after seeing Zhu Zixi's strength. I will not let go of any opportunity to enhance my own strength. ”

"Even if it's with me, a former enemy?" the commander grinned, turning and walking on.

"Even if it's with you, a former enemy. Wu Tie nodded, glancing at the several fog knife killers following behind him.

"Hey, you're not stupid enough to tear your face with me before you take revenge, right?" Wu Tie carried a spear and followed behind the commander step by step.

He stared at the back of the commander-in-chief, and said slowly: "One of my elders told me that when facing a strong enemy, the former enemy, everyone can join forces, isn't that the truth?"

The chief commander laughed.

After walking forward for a while, he spoke: "It also makes sense, but don't you really consider my suggestion?" join the Fog Knife, and I will accept you as a personal disciple." ”

"Compared to the Immortal Sect, my Fog Knife is only an inconspicuous small force in the Cangyan Domain...... However, I am confident that as long as I can return to my ancestral land, it will not be a problem to repel the Immortal Sect. ”

"When the time comes, my fog knife will dominate the Cangyan Domain, and then expand outward, can't you be the new fog knife commander in the future?"

The general commander sold the various benefits of the fog knife to Wu Tie all the way, but Wu Tie just didn't say a word.

On this side of the bridge, there is a square corridor 100 meters wide, the four walls are made of metal, and the ground and walls are carved with extremely thin lines, and soft fluorescence erupts from the lines, indicating the forward passage.

The group walked forward, and every 500 meters or so, there was a heavy metal portal.

On the metal gate, which is 100 meters long and wide, extremely thin lines outline complex patterns, and they are inlaid with extremely thin spars that shine with cold light.

When passing by a half-open metal gate, Wu Tie deliberately knocked on the ten-meter-thick portal with the White Tiger Crack.

There was a loud bang, and the door trembled slightly, and a little dust fell from the top of the door.

The material of the gate is excellent, extremely hard and extremely flexible.

The white tiger crack was so heavy, Wu Tie hit it casually, but he couldn't leave any traces on the portal.

The Chief Commander and several Fog Knife Killers glanced at Wu Tie, and the Chief Commander said proudly, "Haven't you ever seen such a strange thing? These portals are almost impossible to complete by manpower." Even the Lu family, who was the best at casting in the Cangyan Domain, couldn't create such a huge thing. ”

"The background of my Fog Knife Ancestor is not something that ordinary people can imagine. The chief commander smiled brightly: "Don't you really think about it? If I want to revive the fog knife, I need talents." ”

"How do I feel, it's either a prison or a ...... It's a sanctuary. Wu Tie ignored the commander's order and muttered to himself.

The face of the chief commander changed slightly.

The group stopped, stood in the corridor and looked back and forth for a while.

In the dark corridor, the faint light emitted from the thin fluorescent lines illuminates the entire corridor, which is not as bright as the void sun, but it is enough to see the details of the surroundings.

The straight square corridor, every 500 meters or so, there is a 100-meter-thick metal gate.

The heavy metal gate was not fully opened, but a gap of more than ten meters was removed from the left and right for people to pass through.

This posture ...... As Wu Tie said, it's either like a prison or a place of refuge.

"I don't know how many years this place has been. Wu Tie walked to a large door, carefully examining the deep lines carved into it, as well as the tiny crystals embedded in the lines.

I don't know.

Unrecognizable.

The intricate patterns of these patterns, as well as these tiny crystals, must have their wonderful uses, but Wu Tie can't tell them anymore.

There is an extremely large reserve of knowledge in his mind, but most of it cannot be called, Wu Tie looked at it for a long time, and he was still confused.

The chief commander was silent for a long time, and then snorted coldly: "Let's go, there are dangers lurking in this corridor, if it weren't for me leading the way, if it weren't for the secret method left by the ancestors of the Fog Knife for generations, we would have died here countless times." ”

Walking along the road, they passed through a total of 12 metal portals up to 10 meters thick, and the group came to a metal cave.

In front of him is a square cave with a length and width of several miles, and a height of nearly a thousand meters.

Metal trestle bridges stretch from the ground to the top, and many portals are carved into the metal cave walls, some of which are connected by metal trestles.

High in the sky, between the trestle bridges layer by layer, there are also sky bridges that span the entire space.

The dense metal trestle and metal sky bridge make this huge metal cave seem crowded.

Perhaps many years ago, there were many people walking back and forth on these trestles and overpasses, and behind those portals was their living place.

Wu Tie walked into the nearest portal and took a turn, there were some metal utensils, beds, tables and chairs, and the space in each portal was divided into ten standard cubicles, and the furnishings inside were almost identical.

"It's not always comfortable to live here. Wu Tie quickly retreated.

The small cubicles behind the portal are cramped, and they can only accommodate one person to lie down, and behind such a dense portal, so many cubicles can at least accommodate tens of thousands of people.

Tens of thousands of people crowded into this nest-like space.

Wu Tie's scalp was a little numb, and he became more and more sure that this was either a prison or a shelter.

The ancestors of the Fog Knife obviously didn't come from a good background.

Walk through this metal cave and walk through a short walkway, then a similar metal cave.

Along the way, I passed through twelve metal caves, and in front of me was an unfathomable cliff with a width of nearly 100 meters.

This time, the chief commander and several of his subordinates were also much more careful, and Wu Tie also noticed that there were red blood stains near the cliff, as well as some broken metal fragments, and it was obvious that the chief commander had suffered a loss here.

Or the general commander ordered to jump off the cliff, in a sunken stone crack for a while, a metal bridge extended from the opposite side of the cliff, the group walked across the metal bridge, the opposite side of the bridge, is just a small platform with a radius of nearly 100 meters.

"Wu Tie, when you get here, it's up to you. The chief commander looked at Wu Tie solemnly: "Here, it should be the last level to enter my Fog Knife Ancestral Land...... Just ......"

Wu Tie nodded solemnly, he clenched the spear with both hands, a little golden light flashed in the center of his eyebrows, and an invisible force field enveloped the entire platform.

He was always on the lookout for any possible changes, especially the possible changes between the commander in charge and several of his subordinates.

The Chief Commander's face became a little strange, and he muttered, "Ancestors...... I lost the most important credential token to return to my ancestral land. forced us juniors to work so hard......"

Shaking his head, he pulled out a palm-sized piece of blood-colored crystal from his chest and set it in a pit in the middle of the platform.

The octagonal crystals and dimples are perfectly pitch black.

Wisps of extremely fine blood light quickly spread out from the pit in all directions, and a large area of thin blood-colored lines quickly covered the entire platform, and then dense rays of light flew up into the sky, firmly enveloping the entire platform.

The light swirled around him, and his body seemed to float in the air.

Wu Tie looked around nervously, and after about a quarter of an hour, their feet suddenly sank, and everyone came to a huge sandstone Gobi cave.

There can be a circular cave with a radius of two or three hundred miles, and the dome above can be thousands of meters from the ground.

There was black grit all over.

Wu Tie bent down and grabbed a handful of fine gravel, he frowned, this was not ordinary sand, but black glazed sand after the sand and gravel were burned by the high temperature.

The muffled sound of 'rumbling' came from afar, and a few miles away, huge metal golems with a round life, seven or eight meters high, roamed around slowly.

At first glance, there are at least a thousand such giant metal golems.

In their left hand is a metal ball full of sharp spikes, and in their right hand they hold an oversized weapon with a handle, including knives, axes, clubs, and hammers.

These big guys roamed in this black sand plain, and as far as Wu Tie could see, piles of huge white bones could be seen everywhere on the black sand and stone Gobi.

These white bones are often hundreds of meters long, and they are stuck in the sand and stone like arches, and these puppets shuttle back and forth between the white bones, occasionally hitting the white bones with a loud bang.

"We're going over there!" the commander bent down and grabbed the octagonal blood-colored crystal from the ground and put it in his arms.

Wu Tie's pupils narrowed.

They had just been on a small platform, and after the commander ordered the crystal to be set in the middle of the platform, they were sent here, and the crystal arrived.

Obviously, this crystal is a pass in and out of this sandstone Gobi cave.

Wu Tie stared at Chief Palm Lin's chest very seriously.

The Chief Commander noticed Wu Tie's gaze, and he smiled and pointed forward, "We're going to cross this plain...... These big guys are indestructible and have infinite brute strength...... We rushed several times, suffered heavy losses, but we couldn't get through. ”

Wu Tie frowned, he smashed a large stone beside him with a shot, and with a single stroke, a huge force combined with an invisible force field threw a stone the size of a water tank.

The boulder roared and flew out of the air for miles.

A metal puppet on the ground raised its left arm violently, and the spiny metal ball the size of a water tank on its left arm flew out with a 'bang', and slammed into the boulder, smashing the boulder into countless pieces.

The metal ball froze in the air for a breath, spun rapidly in place for hundreds of circles, flew back with a 'boom', and pieced together on the metal golem's left arm.

"It's indestructible, it's brute force, and it's all over the place. The face of the chief commander twitched violently, and he looked at Wu Tie and said in a deep voice: "Several of my loyal dead soldiers were smashed into meat sauce by these metal balls. ”

"So, I need someone with enough brute strength and strong enough defense to help me stop these guys. The chief commander looked at Wu Tie very seriously: "I don't know, you can't do it." ”

Wu Tie's face twitched, he looked at those huge metal golems, and imagined the crazy scene of the metal balls hitting the sky, and he couldn't help but shiver.

"Try it. Wu Tie told the chief commander very frankly.

"Don't force it. The chief commander also looked at Wu Tie very frankly: "Although, I really want to go to the ancestral land to see, what treasures are hidden in it...... According to the ancestors, the treasure inside can turn things around......"

A trace of horror flashed in his eyes, and the chief commander said in a deep voice: "Perhaps, it can also make me die without bones." But do you want to check it out?"

Shaking his head, the chief commander looked at the metal puppets: "These guys were originally guards guarding the ancestral land...... However, the ancestors lost their identity credentials, so much so that when we wanted to return to our ancestral land, they also blocked us. ”

Wu Tie took a deep breath.

The heart shield behind his chest squirmed violently, quickly turning into a set of white and miserable tight armor that enveloped his whole body.

The eyes of the total palm light up...... He had seen this set of armor on Wu Tie's body, and he knew how strong this armor was.

Wu Tie held the white tiger crack in his hand and rushed out in stride.

The white tiger cracked heavily, and Wu Tie's footsteps were extremely dull and loud, and the metal golems wandering near and far looked at it at the same time, and they strode towards Wu Tie, and then flicked their left arms at the same time.

Metal balls the size of a water tank erupted wildly, extremely fast, pulling out clearly visible white tracks in the air.

Wu Tie waved the white tiger crack.

The spear swung in a perfect arc, and the head of the spear shaped like a short sword slashed rapidly, and in the shocked gaze of the chief commander and several fog knife fog knife killers, these metal balls that puzzled them for a long time and couldn't solve them were actually easily cut by Wu Tie.

Large sparks erupt from the metal ball, and the severed metal ball can never fly back.

In just a few breaths, thousands of metal golems lost their ranged attack weapons at the same time.

Wu Tie laughed and ran forward with the white tiger's cracked legs.

The chief commander also laughed loudly, and hurriedly followed behind Wu Tie with a few subordinates.

Without these heavy weapons of long-range attacks, these metal golems would not be able to move very fast, and they would not be able to keep up with Wu Tie and the others.

After running wildly for a long time, a black cliff in front of me was in sight.

A large black hole in the cliff stands out.

Outside the black hole, there was a huge skeleton nearly a kilometer long.

It was a hideous hydra skeleton, and the pitch-black skeleton was still emitting a faint black aura in all directions.

"Hydra?" the chief commander shivered subconsciously, his veins throbbed violently, and black lines flashed under his skin.

"It's ...... Warcraft Xiangliu. Wu Tie was also shocked.

This is not a hydra, but an ancient troll, or an ancient demon god...... The great murderer is the willow.
