It is also known that he is now in a critical moment of life and death, as long as he can grit his teeth and get through that difficulty, he will be able to break out of the cocoon into a butterfly and fly into a dragon! Once this difficulty cannot be survived, what awaits Gu Lin is complete failure, and the end of failure is ashes!

And Gu Lin obviously knew the seriousness of the matter, so he also gritted his teeth tightly, trying his best to maintain his current extremely vague consciousness.

It can be said that after the experience of nine deaths just now, the Blood Flame Worm has used the power of the Blood Flame to suppress the Heavenly Vein, and it will no longer pose a danger to Gu Lin's life for the time being, so what Gu Lin needs to overcome now is this inhuman suffering!

This feeling of being burned by the flames can no longer even be described as painful, it is almost like being in an infernal hell rolling back and forth in the sea of swords and fire, Gu Lin feels that every inch of his flesh and blood is being desperately squeezed dry.

And once he couldn't bear it in the face of this pain, Gu Lin's consciousness would immediately fall into a coma, and at that time, this refining Heavenly Vein would completely end in failure!

Thinking of this, Gu Lin gritted his teeth fiercely, and then pinched himself fiercely, trying his best to maintain the last trace of his sober consciousness, and at the same time, Gu Lin also slowly forced the origin qi of the heavenly veins towards the bronze fire gate.

It stands to reason that the place where the human body refines the spiritual veins should belong to the dantian, but the Blood Flame Worm has already told Gu Lin before that the fire gate in the bronze ancient stone in his body can also be used as a place to store the spiritual veins, so it is possible for Gu Lin to refine the four spiritual veins.

So Gu Lin now also wants to try whether what the Blood Flame Worm said is true. After all, if this bronze ancient stone can really help Gu Lin refine the four spirit veins, then this will definitely become the biggest opportunity for Gu Lin!

Thinking of this, Gu Lin suddenly shook his head fiercely, and then maintained his consciousness a little, urging the origin qi of the heavenly veins into the bronze ancient stone bit by bit.

And that heavenly vein was filled with extremely powerful and terrifying fire power, and that kind of flame energy even burned Gu Lin's meridians to black! Gu Lin now felt an unbearable devastation in all his internal organs.

So now it can be said that it is the most critical and important process, as long as Gu Lin can send the Heavenly Vein into the Bronze Stone Gate, this Heavenly Vein refining can be said to be a complete success!

However, the distance between the Heavenly Vein and the bronze ancient stone can be said to be extremely short, but this extremely short distance is like a heavenly moat to Gu Lin, because as long as the Heavenly Vein moves slightly, there will be a sharp pain like the bite of ten thousand insects in Gu Lin's body, and in the face of that huge pain, Gu Lin's face has become extremely distorted, and the whole person's face looks extremely terrifying!

Every time the Heavenly Vein moved, Gu Lin felt as if the bones in his body had been smashed by a hammer, but he also knew that in the face of such a desperate situation, he couldn't feel the slightest sense of relaxation, otherwise he would be completely dissolved!

If he knew the seriousness of the situation, Gu Lin's whole person would now be burned as if he had been burned into a burning man, and even his skin had become charred and black, and the power of the raging fire was spreading out of his body, reflecting the entire cave in red.

After enduring so much pain, in Gu Lin's eyes of hope and expectation, the heavenly veins finally slowly moved towards the bronze stone gate.

I don't know how long it took, it was definitely not a long time, but for Gu Lin, it was like a year, but in Gu Lin's gritted teeth, the extremely powerful Heavenly Vein Origin Qi was finally completely forced into the fire gate in the bronze ancient stone by Gu Lin!

Seeing this situation, Gu Lin's tense nerves were finally able to relax a little, and the whole person exhaled deeply and violently, as if he had walked away from the ghost gate!

He only really felt the horror of this celestial vein now, Rao was sent out by the blood flame worm and most of his energy, but once this thing was sucked into the human body, it was like a time bomb, and if he was not careful, he would be blown to pieces immediately!

And Gu Lin is glad that under the double favor of luck and perseverance, Gu Lin finally got through this inhuman pain, that is, he finally boarded the dragon gate, and a earth-shaking transformation is about to occur!

However, although the most important step is completed, it does not mean that Gu Lin can completely relax now, because the process of refining the Heavenly Vein is too long and cumbersome, and it can be said that a little mistake in any small link may cause the final failure, so Gu Lin is not completely able to put down the heart he is carrying now!

Because although the Heavenly Vein has entered the bronze ancient stone or the door, but the Heavenly Vein is an extremely terrifying existence, this thing has even faintly possessed spirituality, with its noble temperament, it will definitely not be willing to stay in the ancient stone like a lamb, but will turn into an undead beast and start a violent impact, so Gu Lin must also find a way to solve these problems.

In addition, there is a more important problem that Gu Lin needs to solve!

This is also about the last energy of the Heavenly Vein, and how much power Gu Lin can exert in the end!

That is, after Gu Lin completely refined this Origin Qi, he used this Origin Qi as the core to help this Heavenly Vein absorb energy again and return to the powerful and terrifying state at the beginning.

After all, most of the energy in the Heavenly Vein has been drained by the Blood Flame Worm, and it has been absorbed by the undead beast, and this is also so that Gu Lin can easily absorb it, otherwise, with Gu Lin's current ** strength, even with the help of the Blood Flame Worm, there is no possibility of refining it at all.

However, after Gu Lin refined the Heavenly Vein, it did not mean that the power of the Heavenly Vein would be like this forever, it was undoubtedly a lot weaker than the original power.

After all, most of the power of the Heavenly Vein has been injected into the origin of the undead beast, and now the power existing in the Heavenly Vein is only a small part of the original, if this is the case, the power of this Heavenly Vein will definitely be greatly reduced in the future.

Therefore, Gu Lin not only had to refine the Heavenly Vein, but also regain its power, let it reabsorb enough aura, and then emit that powerful and terrifying charming power!

But this process is not something that can be done overnight!

Because the Blood Flame Worm drained most of the energy of this Heavenly Vein at once, this Heavenly Vein was accumulated by the endless power of fire for hundreds of thousands of years, and if you want to restore its energy, even with the help of this Origin Qi, I am afraid it will take at least a few months!
