If he hadn't been afraid of wasting this Wind element Spirit Stone, Xu Yi would have given up long ago. That feeling of exhaustion, as if he were on the verge of death, far surpassed having his bones scraped and his heart gouged out.
He had struggled through the inscription of the array patterns on all three Wind element Talisman Papers. Xu Yi had no idea what kind of torment he had endured. That sensation of time freezing was like having his nerves ground to dust, bit by tiny bit.
Even with his powerful Yin soul, he had barely held on until the very end before immediately collapsing into unconsciousness.
Whenever he recalled that agonizing sensation of time freezing, Xu Yi still felt lingering fear.
After putting away the three talismans, he couldn't help but peer inward at his spiritual platform. To his surprise, the little figure within seemed rather spirited, and much more alert.
He suddenly understood. Making three talismans at once had been grueling, and he had pushed his Yin soul too far. But once it recovered, his Yin soul had actually benefited.
It was like training the body: after being pushed to utter exhaustion, the body often grew stronger once it recovered.
Xu Yi had long understood this principle, but he hadn't known how to train his Yin soul. Previously, he had tried inscribing array patterns in his mind. It had produced a slight effect, but nothing significant.
This time, however, his sudden whim to draw three talismans simultaneously had let him stumble upon an effective way to train his Yin soul.
But the moment he thought of that terrible pain, he couldn't help shuddering from the depths of his soul.
Half an incense stick later, he returned to the Immortal Guest Tower and ate his fill.
