About ten seconds after the branches had spread into their body, they begin to absorb the Cosmic Elemental energy.

The speed of absorbing is faster than I had expected, which is a very bad thing as this Cosmic Energy had gone very deep into the twins, and when the branches absorb it at such a fast speed, the pain they give is immense.

"Ahhhhh….."

I had just throught about pain when I heard the blood-curdling scream from the twins. It is a very painful scream, far more painful than my patient gives.

The cosmic elemental energy is no simple energy; it has a connection with the Cosmic Quintessence, thus very hard to absorb. If I had used my strings to absorb it, I would have utterly failed to do that.

It is one of the reasons why I had made the core central part of my plan. I germinate it using the Cosmic Elemental energy and used extremely precious resources, so it could absorb the powerful Elemental Cosmic Energy.

The screams of the twins have become louder, and they are filled with so much pain that I wanted to close my eyes.

The twin's mother is crying; if not for Old Healers Energy enveloping her, she would have come running toward her daughter. The twins need no disturbance; they are at a very critical juncture; they have to bear this pain with their sanity intact, only that way they can get out of this predicament alive.

Hun?

Suddenly, I noticed something which made me very surprised but also brough a smile to my face that I immediately opened my eyes and looked around the formation and saw what I had expected to see.

The formation of the floor and on the twin's body glowing very softly; the work of the formation is already over, but it still doing something. It is taking the energy from the Blood Red Vitality Crystal and fusing with the twin's body.

This stage should have happened at the end when branches finished absorbing all the Cosmic Elemental Energy but started at the beginning.

The vital energy it is taking from the crystals is very small, so others had noticed it yet as all of them are looking at the twin's bodies, but they will soon notice it when the runes begin to absorb the greater amount of energy.

The absorption of Cosmic Element Energy is increasing. Its release of vitality energy into the twin's body had also increased with another change had begun. The phantom of trees that is floating above the twins are slowly becoming bigger and more clearer.

Ten more minutes have passed, and now the size of the tree had increased by five to six inches, and they have become even clearer.

The change of the tree is not only happening outside but happening inside two; the tree shape core in the twin's chest also becoming more solid with the absorption of a greater amount of energy.

The people in the hall had finally noticed the changes that are happening in the hall. The floor of the hall became a little pale compared to other parts of the hall. 

It is clear that runes are absorbing the vitality in blood-red crystals, and it is just a beginning as till now, the branches spread in the body had not even absorbed 10% of Cosmic Elemental energy contained in the bodies of twins.

While most of the things going smoothly, there are some problems occurring too. The rate of Cosmic Elemental Energy entering the twin's body had increased several times.

At the beginning of treatment, it was only five times, but now in less than an hour, it had increased to eight times speed, and its rate is increasing rapidly; within few minutes, it will reach nine times.

It is a good thing, all the Cosmic Elemental Energy coming from outside, directly being absorbed by the core, not a 1% of it absorbed by any other part of the body, which is great. 

Still, I hope it would not increase at such speed, not before the core is fully matured and I begin the next phase of my plan.

I opened my other close eye for a moment and looked at the body of the twins carefully; at first, I did not saw any, but as I looked carefully, I saw the elemental petrification is easing slowly, which pleased me greatly.

With braches of core sucking of Cosmic Elemental energy and pumping vitality into the body, the signs of petrification are easing; I need them to disappeared completely before I begin the next phase of my plan.

A little more than an hour passed by, and 60% of the Cosmic Energy present in the twin's body had been absorbed. Not only that, but the floor I am sitting on had also turned mostly while one could be barely able red in it. 

The runes have absorbed all the vitality present in the vitality crystals of the floor, and now, they moved toward the wall.

A few minutes ago, I detected a tint of pain from the leader of Bloodsun eyes; as she saw how quickly twins are absorbing the blood vitality crystals. If I had been in her place, I would have had the same expression too.

While the Blood Vitality crystals could not be compared to the resources as the Devine Crystals, but the sheer number of crystals present in the tower more than enough to compare to it. Each floor of a tower could be comparable to a piece of Devine Crystal.

The whole tower worth several divine crystals.

With such progress, the visible change had occurred into twin's skin; the elemental petrification had been reduced by a huge degree, and rock-like skin had nearly vanished, but one could some signs of flesh the faint layer of fiery red and snow white.

While everything may seem like going great, it is not. The cosmic energy had increased at the speed of twenty-two times, and it is increasing rapidly.

If it continued increasing at such speed, then I would have to bring the next phase of the plan lot earlier than I had decided, and there is substantial risk in doing that, but the rate of cosmic elemental energy coming at twins leaving me no choice but to take the risk.
