Zhang Yang entered seclusion.
The reason was those six hundred thousand First-Grade Foundation Establishment Pills.
That was truly a staggering number. It was estimated that even in the Immortal Cultivation World, no one had ever swallowed spiritual pills like a whale, right? Wasn't he afraid of indigestion?
But that was exactly the stupid thing Zhang Yang had done.
He wanted none of the Foundation Establishment spiritual effect from the First-Grade Foundation Establishment Pills. He only wanted the wisp of spiritual qi inside them; everything else was wasted.
Thirty thousand First-Grade Foundation Establishment Pills could produce one thousand breaths of Natal Spiritual Qi.
Six hundred thousand First-Grade Foundation Establishment Pills could produce twenty thousand breaths of Natal Spiritual Qi.
Zhang Yang's calculations were extremely accurate, and he carried them out without hesitation.
After three months of seclusion, he had consumed one hundred thousand First-Grade Foundation Establishment Pills and obtained three thousand breaths of Natal Spiritual Qi.
He immediately poured them into the Soul Meridian Sword Core. That was right—the first layer of the Soul Meridian Sword Core only required 300 breaths of Natal Spiritual Qi, the second layer only required 500, and the third layer only required 1,000. Upon reaching the fourth layer, however, it required three thousand breaths of Natal Spiritual Qi.
That was a colossal number. Zhang Yang did not know whether obtaining Heaven and Earth Spiritual Qi was easy in the Immortal Cultivation World, but even if he cultivated every day and obtained ten breaths of Natal Spiritual Qi daily, those three thousand breaths would still require a full year of bitter cultivation.
If he wanted to break through the Soul Meridian Sword Core to the fifth layer, he might need ten thousand breaths of Natal Spiritual Qi.
For the time being, he did not even dare think
