And today, they were lucky enough to encounter this endless magma power, and the next time they wanted to open the other two bronze doors, it would definitely not be that simple.

After all, it is definitely very difficult to find a place where the aura of heaven and earth is extremely abundant. It can be said that in the future, if Gu Lin wants to open those bronze doors, he can only use a large number of elixirs to urge them.

However, although there was a bit of a headache in his heart, the Blood Flame Worm also knew that this was all for the future.

Gu Lin obviously knew the priority of the matter, and now that this bronze door had been completely opened, his top priority now was to quickly find a place to refine this celestial vein.

With his current strength, if he was able to refine this Heavenly Vein, not only would the black fire disease in his body be able to get a chance to be solved, but even his strength would definitely improve by leaps and bounds.

After all, the energy contained in this celestial vein would definitely make even a Spirit Desolate powerhouse feel terrified, and if Gu Lin could absorb it thoroughly, his strength would definitely reach an earth-shaking transformation.

Thinking of this, Gu Lin suddenly no longer had the slightest hesitation, quickly spread out his body, and then slowly flew towards a place in the Ten Desolate Medicine Mountain.

Because of the battle with the beast just now, Gu Lin's physical condition can be said to be extremely bad now.

Now his entire body was covered with bruises, and there was a large stream of blood flowing outward, the bones in his body felt like they were about to be completely shattered, and the meridians were even more painful, like the bite of ten thousand insects.

It is even no exaggeration to say that Gu Lin has almost reached a point where he is exhausted, and now even if a spirit desolate powerhouse appears, he may be able to kill Gu Lin here.

Therefore, if Gu Lin wanted to refine the Heavenly Vein safely, he had to find an extremely safe place to completely refine the Heavenly Vein.

Otherwise, if he was carrying such a heavy treasure, if he was discovered by a strong man who cared about the people, Gu Lin believed that his fate would be extremely miserable.

After all, the husband is not guilty, and Gu Lin knows the truth of his guilt.

Not to mention that his current strength has almost completely lost, even if his cultivation in the Spirit Ancient Realm is still there, in the face of a treasure like the Heavenly Vein, which countless people are eager to grab, there will definitely be many strong people who will snatch it with red eyes.

Therefore, Gu Lin flew in the Ten Desolate Medicine Mountains for a long time, and after careful inspection, he finally determined an extremely stable place.

It was an idyllic valley, and the entrance to the valley was like a rock splitting straight down from the sky, leaving a thin crack that could only pass through one person.

Moreover, those seams are surrounded by weeds and trees, and it is impossible for ordinary people to find such a place.

Even if it were a coincidence that the trees and grasses were to be found here, it would be impossible to find such a non-existent entrance.

Knowing that this was the safest place within a radius of hundreds of miles, Gu Lin suddenly dragged his bruised body and slowly walked towards the valley.

The inside of this valley was extremely vibrant, with trees and lush grass, and the aura in the air was also extremely rich, which was definitely of great benefit to cultivators.

Gu Lin searched carefully, and finally found an extremely secluded cave, so he dived into it headlong, ready to start taking the Heavenly Vein.

Gu Lin's current strength had reached the seventh order of Lingxuan, and this was all thanks to the medicine witch worm in his body.

That medicine witch worm can be said to be an extremely rare treasure of heaven and earth, after all, as long as you can feed him enough elixir, what level he can grow to, your strength can also be improved to the corresponding level, this is definitely a treasure for many people!

And after Gu Lin's feeding, this medicine witch worm has now reached the peak of the second order, so Gu Lin's strength has also been improved to the corresponding seventh order of Lingxuan.

It stands to reason that this creature is extremely anti-heaven, so the heavens also have an extremely powerful suppression of this creature, and it can be said that few medicine witch worms can reach the third order. Otherwise, if he had an extremely large strength but fed him elixir, that kind of behavior would probably be like a rocket.

Something like this is obviously hard to happen!

However, Gu Lin remembered that the Blood Flame Worm had told him that although the ordinary Medicine Witch Worm could only reach the peak of the second order, the Blood Flame Worm had an extremely high status in the Witch Worm Clan, and he said that he had a way to upgrade this Blood Flame Worm to the third order.

Therefore, before absorbing and refining the Heavenly Vein, Gu Lin should also ask the Blood Flame Worm to upgrade this Medicine Witch Worm first.

In this way, Gu Lin was able to maximize the improvement of his strength this time.

"By the way, I remember you told me that you could upgrade this medicine witch worm, do you think it's time to make a move?"

The Blood Flame Worm felt the medicine witch worm in Gu Lin's body, if you knew that there was still room for upgrading, if Gu Lin completely refined the Heavenly Vein, and his strength skyrocketed, it would be in vain to raise the level of this medicine witch worm at that time.

After all, once your strength far surpasses that of this medicine witch worm, this medicine witch worm can be said to be completely useless!

Therefore, in order to maximize Gu Lin's strength this time, he should also take action to upgrade this medicine witch worm now.

Seeing that the Blood Flame Worm nodded and was about to make a move, Gu Lin suddenly asked with a curious expression: "When you upgrade, do you still need an elixir or something?"

When he asked this, Gu Lin was also a little apprehensive in his heart.

After all, there is really nothing left in his hands now, except for those two, the rest of the medicine kings can still be used, and some low-level elixirs Gu Lin are also gone.

However, there was one in the Medicine King that could not be used at all, because the Blood Flame Worm had told him that the purple Medicine King might just be a descendant of an elixir differentiation, and even if Gu Lin tried all the methods, he would not be able to absorb it at all.

Alas, if you use another medicine king just to upgrade the medicine witch worm, this kind of practice is inevitably a bit too extravagant!

After all, if nothing else, even if he took this medicine king directly, the improvement of Gu Lin's strength would probably not be a little bit higher.

Moreover, this medicine king can be said to be the only elixir that Gu Lin can use now, and he can only use the power of the blood flame worm when he uses the elixir as a reliance, so this elixir is undoubtedly Gu Lin's last hole card!

If this elixir is used now, Gu Lin will not have the slightest power to fight back when he sees a strong man like the Poison King in the future, and he will only have to flee for his life!
