The spiritual energy in his Qi Sea was the grandmist purple spiritual energy transformed by the Supreme Pagoda, so there was no need to mention the degree of purity.

If other people's spiritual energy was water vapor or fog, then his spiritual energy was water. Moreover, it was extremely compressed water.

The Qi Sea was like a bottle. If it was filled with mist or mist, it could be mixed with other things and wouldn't be full. However, if it was filled with tangible water, it wouldn't be able to be filled with any other things.

Before releasing that ball of grandmist purple spiritual energy, his aurasea was already filled to the brim. Once it was released, it immediately became like a bottle filled with water, forcefully filled again, and with a bottle stopper tightly stuffed.

One could imagine the result of this.

Lingyun's Qi Sea felt like it was bursting with spiritual energy. A pain that felt like his flesh was being torn apart entered his mind, causing his face to contort.

The wall of the Qi Sea was constantly moving. What Lingyun needed to do was to endure the pain and continue to pour spiritual energy into the Qi Sea.

Of course, he still had to be careful not to explode, directly causing the spiritual energy to explode. That way, his body would be smashed to smithereens.

He couldn't afford the consequences of that.

He could only open up a part of the bottle, the bottle with the Qi Sea, bit by bit.

Unknowingly, he had already sat down cross-legged. His handsome face was covered in sweat, and his expression was twisted, as if he was enduring an indescribable pain. He bit his lips, and bright red blood seeped out.

"AHH!" Lingyun let out a low roar, and the Grandmist Paragon Incantation began to circulate subconsciously as well. Spiritual energy continued to howl as it entered his body, entering the Supreme Pagoda, and then gushing out.

This only made his situation worse.

The spiritual energy in Ling Er's body fluctuated non-stop. Strands of red spiritual energy were being emitted from her body. She had reached her current cultivation limit and could break through at any time.

However, seeing Ling Yun's current state, how could he have the heart to peacefully break through? Let alone breaking through, when the time came, she would be full of distracting thoughts.

Ling'er was from an extraordinary background, and was experienced and knowledgeable. Naturally, she knew what Ling Yun was currently doing, and could not help but curse inwardly. However, she could not help but feel worried.

However, there was nothing she could do about it. She could only rely on Ling Yun and stomped his feet.

There was no turning back when one chose to expand their aurasea. There were only two possibilities. Since ancient times, there had been no exceptions.

The first result was naturally success. By expanding one's Qi Sea, one could increase the amount and density of spirit energy stored within the same cultivation level, as well as increase one's battle prowess.

This was a good result, something countless experts yearned for.

The second result, which was the worst result, was that it couldn't expand. The spiritual energy in the Qi Sea lost control and started to revolt.

The Qi Sea barrier was strong enough to withstand the impact of the spiritual energy, and it was possible that he would benefit from this disaster and successfully expand his Qi Sea.

However, this was just a conjecture. No one had ever succeeded before. Most of them had lost control of their Qi Sea, causing explosions. The Qi Sea had been blown up and their people had been turned into ashes.

If the Qi Sea barrier wasn't solid enough, it would be broken by the Qi Sea which had gone berserk. The Qi Sea would explode, and the Qi Sea would destroy the Qi channels.

Other than these few possibilities, there were no other possibilities.
