"Not bad, it seems?"

Shen Yi opened his hand and let that uncanny gray-white armor disperse.

The great formation drew swiftly back in around him and settled again at his heart.

He had not much wanted to go deeper into formations.

In most of the situations he met with nowadays, after all, there was nobody to buy him time so that he could lay out a great formation in peace.

Learning a little shallow formation work against unexpected need was one thing; a spirit-formation like this, which ate a terrifying amount of lifespan, struck Shen Yi as poor value.

But the case now was plainly different.

This Guixu Immortal Armor Formation was carved into his body and could be brought up at any moment. What the former Nanyang Sect Master had produced was indeed the thing best suited to close-quarters fighting.

And having felt out its effect a little.

It was at the very least no weaker than Heavenly Reckoning Forty-Nine.

"Hff."

Shen Yi steadied his breathing and looked at the demon lifespan he had left.

【Remaining Demon Lifespan: 427,000 years】

The great difference between the Guixu Immortal Armor Formation and Heavenly Reckoning Forty-Nine was this: once he was past Xuanqing's insights, working the Forty-Nine out on his own had made no headway whatever, and had come near to driving that heap of demon remnant thoughts into collapse and extinction.

But the Guixu Immortal Armor Formation… was merely slow.

If there was progress, that meant it could be pushed!

Before Shen Yi had even begun drawing on the demon lifespan, he felt a touch of nausea rising.

If he remembered rightly, a technique of this brain-taxing sort he had at most worked out for a few tens of thousands of years before — something on the order of the Parting-Flame Heart-Burning Palm — but set beside a true Return-to-Void spirit-method, that was a lesser shaman standing beside a greater.

He went back to that mountain peak again.

And sat down cross-legged once more.

A vast mass of demon lifespan poured madly into the spirit-formation method.
