Cang Su had almost never used this rare elixir related to spiritual power.
Firstly, it was because this kind of elixir was too rare, but also because Cang Su was not sure whether taking this kind of elixir would be good or bad for her.
However, now, Cang Su had to use this elixir for the Tian Yuan Cauldron.
Thinking of this, Cang Su quickly made the hand seals according to the content on the scroll.
He even softly recited the abbreviated spell on the scroll, and bursts of spiritual power quickly surged from the center of Cang Su's brows.
The powerful spiritual power immediately shattered the ice jade bottle, and the ice liquid inside twisted in mid-air, and then continued to change rapidly with Cang Su's movements.
Gradually, it condensed into a key, and the ice liquid slowly but effectively moved under the power of Cang Su's spirit.
Feeling that his spiritual power was like a pair of invisible palms constantly rubbing the ice liquid, the solemnity in Cang Su's eyes did not diminish at all.
The prototype of the key soon appeared, and a drop of cold sweat quickly fell from Cang Su's forehead.
And at this moment, Aozun on the side also reminded with a solemn expression, "Take the Jiheng Bone Pill, otherwise you won't be able to bear it once the seal is released."
After listening to Aozun's words, Cang Su took the Jihenggu Pill without hesitation.
Before the effects of the Ji Heng Gu Pills could take effect, Cang Su made a sudden move and put the key condensed from the ice liquid into the huge transparent lock.
Immediately, there was a loud "click" sound, and Cang Su's heart also froze.
"Kakakaka!" The giant lock was lowered, and there was a loud noise immediately, and then the chains wrapped around the Tianyuan Cauldron were cut off piece by piece.
The flame aura above the Tianyuan Cauldron suddenly moved faster and faster, and sparks appeared one after another.
The last chain finally fell to the ground. Immediately, the blue-white flames in the Tianyuan Cauldron surged up, broke through the medicine cauldron, and rushed towards Cang Su.
Waves of mental coercion that made Cang Su's scalp numb came roaring in, bringing with it a force that could destroy the world.
A drop of cold sweat suddenly fell from his forehead, and Cang Su quickly activated the power of Ji Heng Gu Pill in his body.
I saw a huge silver rib cage suddenly emerging from Cang Su's body, and then firmly protecting Cang Su within it.
As soon as the silver skeleton appeared, the bluish-white flames from that side also came like a powerful force and hit it hard.
An invisible barrier appeared in front of the skeleton, completely blocking the blue-white flames and not harming Cang Su inside at all.
"Don't relax! It's not over yet!" His eyes were still sharp, and Aozun squeezed out these words through his teeth.
Naturally, he didn't dare to be careless, so Cang Su quickly activated the power of the elixir in his body.
Suddenly, the silver-white light of the huge rib cage became more dazzling, illuminating the entire sea of fire as bright as day.
However, this was not enough to make the blue-white flame retreat.
Only an old roar could be heard from the flames, and then the flames became even stronger, condensing into a flaming wolf and slamming towards Cang Su.
Cang Lang let out a sharp howl, and his huge head slammed into Cang Su's ribs.
Silver and white against blue and white, they immediately eroded each other and refused to give in to each other.
The silvery white light suddenly disappeared a lot, and some thin cracks appeared on the huge rib frame.
Seeing this, Cang Su frowned slightly.
Although the defensive power of the Jiheng Bone Pill is very strong, it is the remnant soul of a powerful person at the heavenly level, so its power is naturally extraordinary.
Naturally, he didn't expect a single pill to be able to withstand the remnant soul of the Demon Fire Heavenly Man. Cang Su knew that this was just the initial attack, as long as he could sustain the wave of attacks, that would be enough.
Thinking of this, Cang Su's mind moved, and a touch of spiritual power quickly covered the skeleton, and then quickly smoothed the cracks on the ribs.
