It was precisely because of this that Ling'er was so worried. This fellow usually seemed to be very rational. Why was she so reckless this time?

There was naturally a precedent for successfully expanding one's Qi Sea, but those were the proud sons of the major powers. Their foundations were deep and their foundations were solid.

Furthermore, when one expanded their aurasea, there would be experts at the Martial Saint level or higher guarding at the side, protecting them.

"At most, I can just suppress the raging spiritual energy in his body at the last moment to prevent his body from exploding and killing him, and protect his little life!" Ling'er's expression became slightly ugly. After hesitating for a moment, she gritted her teeth and sat cross-legged beside Ling Yun.

She stared at him with her beautiful eyes. From the looks of it, she was already prepared for the worst case scenario. She was ready to suppress him at any moment.

Lingyun naturally did not know what Ling'Er was thinking. Right now, the Spiritual Energy in his aurasea was like the surging waves in the ocean, causing it to vibrate slightly. However, it did not bulge at all, much less expand.

His Aura Sea barrier was too thick. He had been cultivating day and night for more than ten years. Although most of his spiritual energy had been devoured by the Spirit Devouring Array, many of it had become nourishment for the Aura Sea, causing it to become extremely thick.

Ling Yun was still crazily releasing that pure and dense spiritual energy, fusing it with the grandmist purple spiritual energy without even the slightest gap.

Stretching, this was the simplest and most crude method he had ever used. He used pure and dense spiritual energy to push his Qi Sea to its maximum.

To other people, this method was simply courting death, but to him, it was not the case. Other people's spirit energy would be refined to a pure state, and there would still be minute impurities seeping through.

If he was not careful, it might cause a disturbance in his spiritual energy and cause a riot. At that time, his Qi Sea would explode instead of expanding.

But Ling Yun did not have to worry about any of this. The Primordial Purple Qi was transformed from the Supreme Pagoda, and it was incomparably pure without any impurities.

It was just like the primordial purple energy of heaven and earth. It could contain other spiritual energies and there was no need to worry about it exploding.

Furthermore, the Aura Sea Barrier was sturdy, so there was no need to worry about it being destroyed. At the very least, with his current Aura Sea Barrier, it would be difficult for even a Martial King to break through.

What he needed to endure was endless pain.

"What a waste of time!" Very quickly, Lingyun frowned. His Qi Sea barrier was too solid, even more solid than he had imagined. If this were to continue, it would take at least three to five days.

What made him feel fortunate was that just now, when he had fully circulated the primordial spirit technique to absorb the spiritual energy of heaven and earth, even after filling his aura sea, there was still a portion of it stored inside the Supreme Pagoda for him to use.

"Let's go all out!" After hesitating for a moment, Ling Yun's eyes flashed with a hint of viciousness, as if he had made up his mind. His hand seal changed, and strands of pure grandmist purple spiritual energy attached to the Qi Sea barrier and exploded.

Seeing Ling Yun's body suddenly tremble like a sieve, Ling'er, who was sitting beside him, slightly frowned, and could faintly hear the buzzing sound coming from within his body.

"What is he doing?" Ling'er's eyes were filled with doubt.

"Wow!" Suddenly, Lingyun opened his mouth and spat out a mouthful of blood.

"What's the matter with you?" Ling'er also did not expect Lingyun to suddenly vomit blood. She panicked, only to see Lingyun ignore her, and cough out blood as if it was free. Very quickly, the blood dyed the white robe on his chest red.
