You must know that although Gu Lin has a lot of secrets on his body, in his opinion, this bronze ancient stone is definitely the largest and most mysterious thing in his body.

Even the well-informed Blood Flame Worm didn't know anything about this bronze ancient stone.

But Gu Lin knew that it was definitely not a mortal thing!

After all, the original Blood Flame Worm's primordial spirit had been completely shattered, but now it was able to come back from the dead because of this bronze ancient stone. At that time, even the Blood Flame Worm was stunned in the face of this situation.

Obviously, the collapse of the primordial spirit is definitely a dead way to die that cannot be re-died, and even the Blood Flame Worm may not help. But this bronze ancient stone breaks common sense!

Moreover, after Gu Lin injected enough spiritual energy into it, he found that there were four small but extremely ancient vicissitudes of doors inside the bronze ancient stone.

The four bronze doors seem to have come through time through endless years.

At that time, after he poured all the energy of the Ghost Yin Taro into a bronze fire door in the Immortal Domain, the fire door miraculously opened.

Although Gu Lin was not sure what its effect was at the time, after the Blood Flame Worm's guess, this fire gate was probably able to be used as a storage place for the human body's refining spirit veins.

And this is definitely the place that shocked Gu Lin and the Blood Flame Worm the most!

In general, this bronze fire door should be of no use in the slightest.

After all, everyone has a dantian in their body to refine the spiritual vein, but there is also a limit, each dantian can only refine one kind, which means that a person can only have one spiritual vein at most.

If there are too many, the spiritual veins of different attributes will have a rejection reaction, and if you forcibly contain them, I am afraid that the final result will be that the dantian will collapse and explode and die.

But if this bronze fire door can really be used as a storage place for refining fire attribute spiritual veins, that means that the other three bronze doors can also refine spiritual veins!

If it were to be calculated in this way, it would come to a conclusion that made Gu Lin even the Blood Flame Worm dumbfounded—with this bronze ancient stone, Gu Lin might be able to refine the four spirit veins!

If such a thing spreads, I am afraid that even in the Spiritual Qi Continent, it will definitely set off a violent turmoil.

After all, everyone can only refine one spiritual vein, which is almost common knowledge in the Spiritual Qi Continent.

Of course, there are some extremely anti-heaven physiques, due to their own mutations, they may be able to break this restriction, and they have two attributes and can refine two spiritual veins.

But that's pretty much the limit!

On the Aura Continent, I hadn't even heard of anyone who could refine three spirit veins, and as for four, it was simply a legend like the Arabian Nights.

After all, after seeing the battle between the Poison King and the Moon Queen on the Fire Desolation Domain, Gu Lin also had some understanding of the powerful Heavenly Veins in the Desolate Beast's body.

A celestial vein is to make the spiritual desolate powerhouse so desperate, it can be imagined how much the strength of refining a celestial vein will increase!

And if that bronze ancient stone is really capable of refining four spiritual veins, and these four spiritual veins must all be heavenly veins, that kind of terrifying power is probably not an exaggeration to describe it as burning mountains and boiling seas.

Of course, there is another situation where even Gu Lin feels terrified when he thinks about it, and even the Blood Flame Worm trembles all over his body when he thinks about it, and that is refining the four Origin Heavenly Veins!

The Blood Flame Worm has already explained to himself in detail the Origin Heavenly Vein, this holy relic is born with heaven and earth, representing the will of heaven and earth, even the extremely powerful Heavenly Vein can only be obediently surrendered in front of it.

It can be said that every Origin Heavenly Vein is tearing the heavens and the earth, shocking the heavens and crying ghosts and gods, and has endless power.

As long as you refine any one, I am afraid that you can call the wind and rain in the Aura Continent, if you can refine the four Origin Heavenly Veins, then such a scene...... Gu Lin couldn't imagine it! Even the Blood Flame Worm was simply unguessable!

After all, if you can really refine the four Origin Heavenly Veins, I'm afraid you can stand at the peak of the Aura Continent and guide the rivers and mountains, and look at the world!

Of course, the Origin Heavenly Vein is extremely precious, let alone four, even refining one is an unattainable dream for ordinary people.

Even the Heavenly Vein, which is much lower than it, is coveted by countless people.

But Gu Lin does have such an opportunity.

After all, he now had a piece of purple jade in his body, and that piece of purple jade Gu Lin was now able to determine that it was related to Emperor Ling Zifeng.

And Di Ling Zifeng is a genuine Origin Heavenly Vein, theoretically speaking, Gu Lin does have a slight possibility of obtaining the Origin Origin Heavenly Vein, although this possibility is very small, and it can even be ignored.

But no one can erase the value of the Bronze Ancient Stone, if Gu Lin can really refine the four spiritual veins because of it, it will definitely be a great killer weapon for him in the future!

Thinking of this, Gu Lin suddenly looked at the medicine tomb with deep eyes.

Since I found this ancient bronze stone, there has never been any movement, and it is lifeless, like an ordinary broken stone.

What's inside this medicine tomb, and why does it make the bronze stone react like this?

Thinking of this, Gu Lin's eyes suddenly wandered, and he thought bitterly.

I have also been near the medicine tomb before, and there was no movement in the bronze ancient stone at that time, why did such a change occur as soon as the medicine tomb was opened this time?

It seems that there is definitely something in this medicine tomb that has a lot to do with the bronze ancient stone!

Thinking of this, Gu Lin suddenly lowered his head and tossed.

At this moment, a thought suddenly flashed through Gu Lin's mind, and then Gu Lin instantly opened his mouth wide and muttered, "Could it be the Ancient Coffin of the Burial Heaven!?"

Thinking of this possibility, Gu Lin's face was suddenly full of surprise, and his expression was full of consternation.

Not long ago, Wanbaofang just released the news that the Ancient Coffin of Burial Heaven, one of the nine ancient tombs, appeared in the Ten Desolate Medicine Mountain this time.

And according to Wanbaofang, the last place where the ancient coffin of the burial heaven appeared was the medicine tomb!

It seems that the reaction of his bronze ancient stone may not be related to the burial of the ancient coffin.

Thinking of this, Gu Lin suddenly thought to himself.

If this is the case, it is not difficult to explain the mystery of this ancient bronze stone.

After all, the Burial Heaven Ancient Coffin was the most mysterious of the nine ancient tombs, and no one could know anything about him.

And the bronze ancient stone is actually related to it, and both of these may have a shocking origin!

Thinking of this, Gu Lin's originally hesitant heart finally slowly firmed up.

If there was still some hesitation in his heart just now, but when the bronze ancient stone had this reaction, Gu Lin finally put aside the burden completely this time.

After all, this thing is also a big secret pressed in Gu Lin's heart, and Gu Lin is also eager to find some clues in his heart.

Therefore, after thinking about it again and again, he finally made up his mind and planned to break into the medicine tomb.

However, just as he was about to move his body and go to the depths of the medicine tomb, he suddenly found that Qiu Yin on the side also emitted a burst of purple light, and that kind of light seemed to have a deep resonance with something in the medicine tomb.

Seeing this situation, Gu Lin suddenly looked at Qiu Yin with a stunned face, and his face was full of surprise!
