Wang Daoyuan recalled the situation of the treasure map before. After breaking the seal and revealing the treasure location and treasure hunting route, his divine light was restrained.

Obviously, the treasure map has other uses.

It is precisely because of this that the Purple Thunder Earth Immortal and the Five Thunder Earth Immortal believe that the treasure map will reveal new clues only when it reaches the Iron Stone Pass.

In fact, Wang Daoyuan has already seen all the clues that should be there.

The treasure map still retains a certain power, probably related to the formations along the way.

Thinking of this, Wang Daoyuan took out the treasure map.

As soon as the animal skin appeared, subtle fluctuations of spiritual energy were emitted from the formation in front of him.

Xuanyuan carefully sensed the connection between the treasure map and the formation: "There is a door. As soon as the treasure map was taken out, the formation was affected. There must be some kind of connection between the two."

Wang Daoyuan nodded: "It seems that the means of liberating the formation are hidden in the treasure map."

He stared at the treasure map for a long time, but couldn't see any clues.

Xuanyuan said: "Master, this treasure map contains divine light, and there must be something hidden there. Why don't you give it a try?"

Wang Daoyuan first injected a large amount of spiritual power into the treasure map, but the treasure map absorbed all the spiritual power, but there was no reaction at all.

"This thing is really picky, even my pure spiritual power doesn't care."

In desperation, he had no choice but to inject immortal power.

A bright yellow dragon flew out from his fingertips, then disappeared into the treasure map on the first floor.

After a while, streams of light appeared in the corner of the treasure map.

The streams of light gathered together to form a mysterious restriction.

The moment the restriction was formed, it formed a strong attraction with the formation in front of it.

Wang Daoyuan did not deliberately control the treasure map and let it fly out.

The treasure map flew to the incomplete formation, and the restrictions on the map were integrated with the incomplete formation in front of it.

The spiritual energy within the formation flows smoothly, and the originally incomplete formation becomes complete.

Wang Daoyuan was a little surprised: "Good guy, the formation has not been broken for hundreds of thousands of years, but it has always been a broken formation."

Xuanyuan was stunned and it took him a long time to react.

“Although the Zan Zhen faction’s methods are clever, their biggest flaw is their fragility.

Incomplete formations are most afraid of breaking them with powerful means.

Generally speaking, the formations deployed by the true immortals using the residual formation method may not necessarily be able to block the earthly immortals.

This formation has experienced the turmoil of the war between immortals and demons, and more than 300,000 years have passed.

There are already true immortals in the Qianyuan Realm, but they still can't break this formation.

The methods of those who set up the formation are really unpredictable."

Wang Daoyuan calmed down: "For now, let's not worry about how exquisite this formation inheritance is. Let's break the formation first."

Before he finished speaking, there was movement in the formation in front of him.

Where the treasure map is located, the barrier formed by the formation gradually becomes thinner, eventually forming a gap.

The hole is one foot high and more than two feet wide, and a strong man can easily pass through it.

Wang Daoyuan exclaimed in amazement: "The skill of those who set up the formation is so clever that it is unmatched.

He even left the key to the liberation in the treasure map."

After that, he took the lead and walked in through the gap in the barrier.

I walked along the treasure hunting path for a while, but nothing dangerous happened.

"There's nothing wrong here. Come in."

Lord Ming Lei Shen nodded and walked into the gap in the barrier.

Xuanyuan was timid. He stretched out a turtle claw and poked into the gap a few times.

After making sure everything was okay, he slowly moved in.

Wang Daoyuan casually took back the treasure map, the gap in the barrier completely disappeared, and the entire formation returned to its previous appearance.

Even Ming Lei Shenjun, who didn't understand the formation at all, was extremely surprised.

"Although I don't know the formations, I have seen many mountain-protecting formations from big forces.

But under this formation, those mountain-protecting formations are not worth mentioning."

Many of the arrangements Wang Daoyuan encountered before can be related to the Tribulation Array Immortal, and this treasure map is most likely left by him.

This guy was a formation wizard in the Qianyuan world back then.

The formations he arranged were so unpredictable that even other formation immortals couldn't understand them.

After ascending to the Immortal Realm, I learned a more advanced inheritance, and my formation methods will naturally make a huge leap forward.

With his methods, many formation immortals in the Qianyuan world are not qualified to compare with him.

Wang Daoyuan walked forward according to the trajectory of the black stream of light in his memory. The formations he encountered along the way were easily solved using the treasure map.

After traveling for hundreds of miles through the iron and stone pass with many formations, and with the treasure map in hand, I didn't encounter any obstacles.

The main city of Tieshiguan is already in sight, and there are cracks everywhere on the city wall.

The entire city wall is no longer complete, parts of the city wall have fallen to the ground, and some have even completely collapsed.

Broken wall tiles were scattered all over the floor.

Wang Daoyuan condensed a sword light and slashed at a broken wall brick.

Dang~~

After a crisp sound, the sword glow disintegrated, leaving the broken city bricks intact.

"If you want to damage the bricks on this city wall, I'm afraid you will need the strength of a third-level Earth Immortal."

Xuanyuan chuckled: "Master, you underestimate the methods of the immortal world.

Tieshiguan is a famous pass in the immortal world. When it was built, every city brick was refined according to the level of immortal treasures.

Even the handyman monks must be eighth-level weapon refiners.

Those who inscribed the magic weapon restrictions and formation restrictions were all ninth-level weapon refiners and formation masters.

Any piece of city brick requires the strength of five true immortals or above to shake.

Many city bricks were piled together, and nine true immortals took action to smelt them into one with the foundation.

The entire main city of Tieshiguan is like a huge iron stone crystal.

Coupled with defense systems such as formations, it is difficult for even the Nine True Immortals to break through.

As for the broken city brick you touched before, even though it was shattered like that, even the restrictions were wiped out.

But it was made from iron stone crystal after all, and had also been smelted by the spiritual fire of the nine true immortals.

Without the realm of true immortality, no one can even think of shaking it."

The city wall of the main city of Tieshiguan is a thousand feet thick and a hundred feet high.

On those relatively well-preserved city walls, formations can still operate.

The light on the weapon refiner's restraint flashes, obviously it still works.

More than 300,000 years have passed, and the spiritual veins have also degraded, but their strength is still so amazing.

To be able to defeat Tieshiguan like this shows how brutal the battle was.

Lord Ming Lei was extremely surprised: "According to what fellow Taoist said, this iron stone pass is so strong, how could it become like this?"

Xuan Yuan let out a long sigh: "The nine immortal kings of the immortal world and the ancestor of the demon race, the demon, were in a head-on confrontation. Even the immortal world was shattered, so what does a section of city wall mean?

If the Immortal World had not been shattered, this fragment of the Immortal World would not have fallen into the Qianyuan Realm."

Wang Daoyuan recalled the position in the treasure map where the black streamer finally disappeared, and determined the location of the treasure.

Tens of breaths later, Wang Daoyuan came to a huge stone beside the city wall.

According to the instructions on the treasure map, the entrance to the treasure place is near this huge rock.

This boulder is completely white jade in color, completely different from the surrounding jet black iron stone crystals.

"Xuanyuan, is this stone made of some material from the immortal world?"

Xuanyuan came over immediately, stared at the boulder for a long time, and tapped the boulder several times with his tortoise claws.

"Master, this stone does not look like it was formed naturally."

Lord Ming Lei God also walked over, condensing a ball of black spiritual power in his hand, and then slapped his palm on the boulder.

Pfft~~

The black spiritual power disappeared instantly, leaving the boulder intact.
