Walking past the cliff and standing at the other end of the metal bridge, the general palm turned back at Wu Tie in surprise.

"I'm so curious. Actually, I just wanted to save you for a while. I really never thought you could really come with me."

He patted his left arm with his right hand, and smiled and said, "Do you remember my arm? It was cut off by you. I thought you were so young, and you would always hesitate and fear."

Wu Tie looked at the newly grown left arm of the general palm.

"I have hesitated... I'm afraid, to be honest, there are also." The white tiger split across his shoulder, and Wu Tie rubbed the gun hard: "But after seeing Zhu Zixi's power, I will not let go of any opportunity to improve my own strength."

"Even if it's working with me, my former enemy?" The general's palm grinned and turned around and continued to walk forward.

"Even if you are cooperating with you, the former enemy." Wu Tie nodded and glanced at the several fog knife killers following behind him.

"Hey, you're not stupid enough to get a fight with me before you take revenge?" Wu Tie carried a spear and followed the general's palm step by step.

He stared at the back of the general's palm and said slowly: "One of my elders told me that when facing a strong enemy, everyone can join forces with the past enemies. Is this the reason?"

The general laughed.

After walking forward for a while, he spoke: "It makes sense, but I really don't think about my suggestions? Add the fog knife and I will accept you as my personal disciple."

"Compared with the Immortal Sect, although my Fog Sword is just an inconspicuous small force in the Cangyan Domain... But I have confidence that as long as I can return to the ancestral land, it will be no problem to repel the Immortal Sect."

"At that time, my fog sword will unify the Cangyan Domain and expand outward. Maybe you will be the new fog sword general order in the future?"

The general commander promoted Wu Tie all the way to the various benefits of the fog knife, but Wu Tie just said nothing.

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

The group moved forward, and every five hundred meters, there was a heavy metal portal.

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

When passing by a half-open metal door, Wu Tie deliberately knocked on the door ten meters thick with the white tiger crack.

With a loud bang, the door trembled slightly, and a little dust fell from above the door.

The door is excellent in material, extremely hard and extremely flexible.

The White Tiger Strike was so heavy that Wu Tie could not leave any traces on the portal with a casual blow.

The General Palm and a few fog knife killers glanced at Wu Tie. The General Palm said proudly: "Have you seen such a strange thing? These portals are almost impossible to complete. Even the Lu family, who is best at casting in the Cangyan Realm, cannot create such a giant thing."

"The foundation of my ancestor of the Fog Sword is not something that ordinary people can imagine." The general smiled brightly: "I really don't think about it? I want to revive my Fog Sword, and I need talents."

"Why do I feel that this is either a prison or... a refuge." Wu Tie muttered to himself without paying attention to the general's order.

The face of the general palm changed slightly.

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

In the dark corridor, the faint light emitted from the thin fluorescent traces illuminated the entire corridor, not as bright as Xuri, but it was enough to see the details around it.

The straight square corridor has a metal gate of ten meters thick every 500 meters every 100 meters.

The thick metal door was not completely opened, but the gap was moved away for more than ten meters away and allowed people to pass through.

This attitude...as Wu Tie said, it either looks like a prison or a refuge.

"I don't know, how many years have passed since this place." Wu Tie walked to a gate and carefully looked at the deep patterns carved into them and the tiny crystals embedded in the patterns.

Don't know.

Can't recognize it.

The complex patterns composed of these patterns and these tiny crystals must have their wonderful uses, but Wu Tie cannot tell them now.

There was an extremely huge reserve of knowledge in my mind, but most of them could not be called. Wu Tie watched it for a long time and was still confused.

The general palm ruler was silent for a long time before he snorted coldly: "Let's go, this corridor is full of dangers. If I hadn't led the way, if it weren't for the secret method left by the ancestors of the Fog Sword, we would have died countless times here."

Continue walking along the corridor and passing through a total of twelve metal portals up to ten meters thick, the group came to a metal cave.

In front of me is a square cave about a mile long and wide and nearly a thousand meters high.

Metal trestles extend from the ground all the way upwards, and many portals are carved on the walls of the metal holes. Some portals are faintly shining, and all portals are connected through metal trestles.

High in the sky, there are also overpasses across the entire space connected between the trestle and the trestle.

The dense metal trestle and metal overpass make this huge metal cave look very crowded.

Perhaps many years ago, many people walked back and forth on these trests and overpasses, and behind those portals was their living place.

Wu Tie walked into the nearest portal and walked around. There were some metal utensils, beds, tables and chairs. The space in each portal was divided into ten standard small lattice rooms, and the furnishings inside were almost exactly the same.

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

The small lattice rooms behind the portal have a cramped space and can only accommodate one person lying. Behind such dense portals, so many lattice rooms can at least serve tens of thousands of people.

Tens of thousands of people are crowded in this ant nest-like space.

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

The ancestors of the Mist Knife obviously had a bad background.

Pass through this metal cave, walk through a short corridor, and then another similar metal cave.

After passing twelve metal caves along the way, there is another cliff that is unfathomable and nearly a hundred meters wide.

This time, the General Palm and his subordinates were also much more careful. Wu Tie also noticed that there were bright red blood stains near the cliff and some broken metal fragments. It was obvious that the General Palm had suffered a loss here.

It was still the general commander to jump off the cliff and put it in a slump in a sunken rock. A metal bridge extended from the opposite side of the cliff. The group walked across the metal bridge. On the other side of the bridge, it was just a small platform with a radius of nearly a hundred meters.

"Wu Tie, when you get here, it depends on you." The general's hand commander looked at Wu Tie seriously: "This should be the last level of entering my fog sword ancestral land... just..."

Wu Tie nodded solemnly, he held the spear tightly in both hands, a golden light flashed between his eyebrows, and an invisible force field enveloped the entire platform.

He was always on guard against all possible changes, especially the possible abnormal movements of the General Secretary and his several subordinates.

The face of the general palm became a little strange, and he murmured: "The ancestors... actually lost the most important certificate token for returning to the ancestral land. We are forcing us juniors to work so hard..."

Shaking his head, he took out a blood-colored crystal the size of a palm from his chest and embedded it in a pit in the middle of the platform.

Octagonal crystals and pits are perfectly pitch black.

Widths of extremely thin blood light quickly extended from the pit to all directions. Large areas of thin blood-colored patterns quickly covered the entire platform, and then dense light flew into the sky, wrapping the entire platform firmly.

The light around it rotates, and the body seems to be floating in the air without any force.

Wu Tie looked around nervously. After about a quarter of an hour, their feet suddenly sank and everyone came to a huge sand and gravel cave.

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

The ground is full of black gravel.

Wu Tie bent down and grabbed a handful of tiny gravel. He frowned. This was not ordinary sand, but black glass sand condensed after the sand and gravel was burned by high temperature.

The muffled sound of "rumble" came from afar. A few miles away, giant metal puppets, which were round and seven or eight meters high, were wandering around slowly.

At first glance, there are at least thousands of such giant metal puppets.

Their left hand is a metal ball full of sharp thorns, and their right hand is holding a handful of extra-large weapons, knives, axes, sticks, hammers, everything.

These big guys wandered on this black sand plain, and piles of huge white bones could be seen everywhere in Wu Tie's sight, on the dark sand and gravel Gobi.

These white bones are often a hundred meters long, and are inserted into the sand and gravel like arches. These puppets shuttle back and forth between the white bones, and occasionally their bodies hit the bones and make loud noises.

"We are going there!" The general's palm bent down, grabbed the octagonal blood-colored crystal from the ground and put it in his arms.

Wu Tie's pupils shrank a little.

Just now, they were clearly on a small platform. After the general order inlaid the crystal in the middle of the platform, they were sent here, and the crystal also came.

Obviously, this crystal is a pass to enter and exit this sand and gravel Gobi cave.

Wu Tie stared at the chest of Zheng Zhanglin very seriously.

The general palm rule noticed Wu Tie's gaze, and he smiled and pointed forward: "We want to cross this plain... These big guys are indestructible and have endless brute force... We rushed several times, but suffered heavy losses, but we couldn't rush over."

Wu Tie frowned, and he poked a large stone beside him with one shot. He raised the gun bar and threw out a stone the size of a water tank with a huge force in conjunction with the invisible force field.

The big stone roared and flew out of the air for several miles.

A metal puppet on the ground suddenly raised his left arm, and the prickly metal ball the size of a water tank flew out with a "bang" and hit the big stone heavily, smashing the big stone into countless pieces.

The metal ball was frozen in the air for a breath, and quickly rotated in place for hundreds of weeks, flew back in a "swish" and pieced together on the left arm of the metal puppet.

"Indestructible, with infinite brute force, and these metal balls are hitting everywhere." The face of the general palm twitched violently. He looked at Wu Tie and said in a deep voice: "My loyal dead soldiers were smashed into meat sauce by these metal balls."

"So, I need someone with enough brute force and strong defense to help me block these guys." The general palmer looked at Wu Tie very seriously: "I don't know if you can do it."

Wu Tie's face also twitched. He looked at the huge metal puppets and imagined the crazy scene of metal balls hitting the sky, and couldn't help but shudder.

"Try it." Wu Tie told the general order frankly.

"Don't force it." The general palmer also looked at Wu Tie honestly: "Although, I really want to go to the ancestral land to see what treasures are hidden inside... According to the ancestors, the treasures inside can turn the world..."

A trace of horror flashed in his eyes, and the general palm said in a deep voice: "Maybe, it can also make me die without any bones. But, do you want to go and have a look?"

Shaking his head, the general order looked at the metal puppets: "These guys were originally guards who guarded the ancestral land... However, the ancestors lost their identity certificates to control them, so that if we wanted to return to the ancestral land, we were blocked by them."

Wu Tie took a deep breath.

The heart protection mirrors on his chest were squirming violently, quickly turning into a set of white and tight armor to wrap his whole body.
