Tong Yan must be a smart person, but he really can't figure out now, what happened to this hall master of the Seven Stars Hall to become like this?

He can be sure that there must be a lot of work in this. Maybe it was this Seven Star Hall Master who accidentally touched the mechanism in this Immortal Cave Mansion, or maybe he was persecuted by the people of the Heavenly Alliance.

The only way to solve these questions was to find the person from the Fengtian Alliance. But where would that guy be now?

Looking at the hall master of the Seven Stars Hall who died unexpectedly, he didn't have much sympathy, there is a saying that you can't live if you do your own evil, this guy can even ignore the brothers in his own hall, and he ended up like this, it is completely self-inflicted.

He wasn't in the mood to collect the body for this guy, and there was no way to do that. The only thing he had to do now was to find the person from the Fengtian Alliance who had disappeared.

Since there was no problem here, he had to go back, and then look for clues as he went.

But after searching all the way, he didn't find anything until he returned to the bronze door where he had first entered.

Could it be that the problem arises on this bronze door?

He thought about it for a moment and decided to take a closer look at this unusual bronze door.

The peculiarity of the bronze door should be the dense spells on it. There are so many kinds of charms that no one can say that they can recognize them all. Moreover, if there is a slight difference in the drawing method between two seemingly identical spells, the power and utility of the spell will also change dramatically.

Among these dense spells, Tong Yan also saw a few spells that he was familiar with. For example, there are nine-star divine spells, ghost killing spells, and purification divine spells, etc. But obviously, there are also many that he doesn't know, or even has never seen.

Not to mention anything else, the master of this Immortal Cave Mansion can master so many spells, which is far beyond the reach of many people.

But after looking at these "dazzling" spells, Tong Yan felt a little tricky.

Why did he think this way? In fact, it is not that the more spells there are, the more powerful they are, and many spells will have a spear and shield relationship between them, and when put together, they will not have the effect of one plus one equals two, or even the opposite effect. With so many charms all engraved on the same bronze door, is it rare that they really complement each other? Maybe not necessarily, but it's just a cover-up, a real master charm that doesn't want people to hide in these spells.

If it is said that the possibility of using these charms to manipulate this bronze door at the same time is very small, and there must be another way to actually mobilize this bronze door.

He thought to himself for a while, and decided to clear the fog, as long as he found the "outliers" in these spells, maybe all the problems could be solved.

Without further hesitation, he immediately raised his leg and walked to the side of the bronze door, and then looked at the charm after charm.

It's a stupid idea, but it's the most effective. As long as he concentrates, he will definitely be able to see the clues.

As it turned out, he was right. After more than half an hour, he finally read the charms on the bronze door one by one.

And among these charms, he manifested seven special charms, memorized them, and slowly closed his eyes.

In his mind, he connected the seven charms with threads, and when they were connected, he suddenly understood.

The seven charms are composed of the Big Dipper Seven Star Array, and the Big Dipper Seven Star Array can be used not only as a killing array but also as a trapped array. Most importantly, these seven mantras are by no means good spells, but evil spells. Seven evil curses form the Big Dipper Seven Star Array, isn't it the extremely vicious spell of lore?

At this moment, Tong Yan's brows immediately furrowed tightly. Even if the owner of this Immortal Mansion didn't want others to enter his cave mansion, he really shouldn't have laid down such a vicious formation. What is the difference between this and the ugly deeds of those demons? It's better to destroy this immortal mansion when he ascends to the heavenly realm, and save himself from staying here and harming people.

But then again, how many people are willing to destroy their homes? Even if you ascend to the heavenly realm, I am afraid that you will not forget the years spent here.

It's a pity that there's no point in talking about this now, and now that the matter has come to this, let's think more about how to find that guy from the Fengtian League.

If the people of the Fengtian Alliance didn't die here like the Seven Star Hall Master, then they would have entered the real Immortal Mansion through some means.

Tong Yan is now in the poison killing array laid out on the bronze gate, but there is still no way to go further, or how to enter the real immortal mansion.

But now he can only start from this seven-star array, but what should he do? You can't touch this killing array, right?

After much hesitation, he finally made up his mind. If he doesn't enter the tiger's den to get the tiger, and if he doesn't touch the seven-star killing array, how can he find out what the problem of this immortal mansion is?

It was risky, but he didn't seem to have a choice.

If you want to touch this formation, it is actually not difficult, as long as you inject a wisp of true qi, you can complete it. Although he doesn't have true qi in his body now, he has demonic qi. In essence, demonic qi is actually very close to true qi, except that one is born from the spirit and the other is born from the demon.

However, he did not rashly inject demonic qi into it, but summoned his Heavenly Demon Bone Armor, and used the power of the star source in his body to condense a layer of light on his body. This is his strongest defense now, if he still can't resist this Big Dipper Killing Array, then it can only be said that he should have this calamity today, and there is nothing to regret.

Everything was ready, he took a deep breath, and then a finger struck, and a wisp of demonic energy was instantly injected into the bronze door.

Under the injection of demonic energy, the bronze door immediately glowed with red light, and the Big Dipper Seven Star Array also became more and more dazzling at this moment.

Tong Yan didn't dare to get too close, and hurriedly stepped back.

But before he could gain a foothold, seven rays of light immediately shot out from the seven spells that formed the Big Dipper.

This Big Dipper Killing Array is comparable to an extraordinary formation at a glance, and its power is naturally several times stronger.

Tong Yan didn't dare to despise it, and when he was about to shift and transpose, his body flashed a few times, and he was able to avoid these seven rays of light. But on the other hand, the seven rays of light all fell towards the end of the passage.

He wanted to follow the light to check it, but he didn't expect that several rays of light shot out of the Big Dipper Array.

His reaction was fast enough, but he was accidentally hit in the arm by one of the bundles.

It didn't matter if the light was so wiped, there was an immediate feeling of heaviness in his arm. Immediately afterward, I saw that black gas instantly rose from the place where his arm was hit by the light, and then, his arm actually hardened little by little under the swallowing of this black gas, and inexplicably grew a black stone layer.

What the hell is going on? Is he going to be petrified? No, it's not petrification, it's ...... Instead, it was swallowed up by the stone little by little!
