The first layer of the Treasure-Controlling Formula could be initially mastered at the Nascent Soul Middle Stage, so clearly the method he had used to activate it was wrong.
Then what should he do?
Lin Xuan pondered in some vexation.
"Forget it. I'll meditate first and rest for a while before thinking about it."
With that thought, Lin Xuan took out a few spirit medicines and swallowed them, then regulated his breathing to recover his magic power. After a day and a night, his depleted true essence had been fully replenished, and he began studying the Heaven-Reaching Spirit Treasure again.
This study took another half a day. Lin Xuan cultivated righteous, demonic, and yao arts alike, so what he had learned was naturally extremely broad. Even compared with Lihe Realm cultivators, he was probably not lacking by much.
Yet in this half a day, he used every secret art he knew, and there still was not the slightest effect. In the end, left helpless, he even tried foolish methods one by one, such as hacking it with blades and burning it with fire, but the shield remained like a stubborn rock.
Lin Xuan was speechless. It felt as if there were a mountain of treasure before him, yet he simply could not find the key to enter. One could imagine his gloom.
Of course, he would not give up. After all, Lin Xuan's temperament far surpassed that of ordinary people. Back when he had first stepped onto the immortal path, he had been slighted by his elders and bullied by his fellow disciples, yet he had still devoted himself single-mindedly to bitter cultivation. Now that he stood at the peak of the Human World, he would definitely be able to think of a way to use this treasure.
