As the breeze blew, the leaves rustled. Yi Yun could hear the sound that every single leaf produced very clearly. This Dao Tree was fully integrated with the Heaven and Earth. It was the Heaven and Earth itself, and Yi Yun was outside this world. He was just a passerby.
Thousands of years of life and death passed with a finger snap. Not only humans, even the other billions of lifeforms were just passers-bys to the Heaven and Earth.
Yi Yun listened to the wind and to the rustling leaves, as his thoughts were fully immersed in the Purple Crystal.
Suddenly, Yi Yun seemed to have a pair of eyes that could penetrate through everything as his gaze landed on the Dao Tree.
There were runic patterns on every lead on the Dao Tree which Yi Yun saw very clearly. Yi Yun could even use his vision to penetrate the tree bark, and see the growth rings in the trunk.
This was something even elites from the 12 Empyrean Heavens could not do.
The ancient tree rings circled again and again, a condensation of Great Dao itself.
Over countless years would one tree ring be formed.
"Three thousands tree leaves, 108 tree rings."
Yi Yun saw through it all, but when he tried to see the energy flow trajectories in the tree rings and the Dao runes they contained, he felt like his spiritual energies were rapidly depleted.
This had never happened before. Back then, Yi Yun had used his Purple Crystal's energy vision to see through all Origin energy flows, and the rules that governed the flow of energy were laws themselves. Hence, Yi Yun could easily see through the Great Dao laws. It was the same back in the sword tomb and the Great Empress mystic realm.
However, today, Yi Yun found his spiritual energy failing to hold up while watching the energy flow.
Yi Yun took a deep breath and cut the Purple Crystal's energy vision off. He was in no hurry.
Even if he saw it once clearly, with enough time, he would be able to see the 3000 leaves and 108 tree rings in their entirety.
As the Dao charms gently flowed, the breeze blew at the tree leaves, emitting rustling sounds of Great Dao. This was the truth of Life, and everything that the Dao Tree had seen while standing here for the endless ages.
Yi Yun immediately felt his body being impacted by a surge, as if he was in the rolling rivers of time. Without being able to do a thing, he rolled away.
The more a passer-by peeped, the more he would not be able to withstand the accumulated insights over the endless years.
As the waves tumbled, after an unknown period of time, Yi Yun recovered his spiritual energy again and again. He struggled to peep, seeing each leaf's Dao runes sporadically.
Seeing them clearly was one thing, but to gain any insights from them was very difficult!
Yi Yun suddenly understood that a passer-by was just a passer-by. The amount of insights gained would be extremely limited. It was all borrowed from the Dao Tree.
Seeking enlightenment through the Dao Tree's Dao, and seeing through the Dao Tree's runic patterns did not mean that it would become his own.
Then what should he do?
Yi Yun suddenly recalled the time he cultivated the "Tai Ah Sacred Technique". He had used the Purple Crystal to see through the "Tai Ah Sacred Technique"'s picture of the Sun.
The "Tai Ah Sacred Technique" may be low in quality, but after Yi Yun entered the Great Empress mystic realm, he learned that the "Tai Ah Sacred Technique" had a tinge of connection with the Azure Yang Lord. And the Azure Yang Lord's Dao came from the "Yang God Manual", and the "Yang God Manual" was truly one of the 12 supreme Great Dao formed at the very beginning of the 12 Empyrean Heavens.
Although the "Tai Ah Sacred Technique" was no longer worthy for Yi Yun to gain any further insights into it, the method that Yi Yun used to gain the insights from the picture of the Sun back then was not necessarily unusable. And that was… copying.
