Li Si floated in midair, staring at the system panel before him in surprise.
The heavily injured Brett saw that Li Si was not continuing his attack. Wary, he could only stay put and refrain from making any moves.
Li Si paid no attention to Brett. To him, the notification on the system panel was far more important.
Extraordinary Domain Wisdom!
This was the boon Li Si had requested when he personally came into contact with World Tree Yggdrasil.
Strictly speaking, Li Si had not directly obtained the power of Extraordinary Domain Wisdom from World Tree Yggdrasil. Rather, he had been given the opportunity to master the Wisdom Domain.
As the embodiment of certain traits of Gaia World's source power, World Tree Yggdrasil possessed such an ability. Otherwise, not even a chief god with Greater Divine Power could grant Li Si such a precious opportunity.
The trial Li Si had undergone had undoubtedly been granted directly by Gaia World's source. Otherwise, he could not have personally experienced the entire history of Gaia World, from its birth to the present day.
It was as though he had witnessed firsthand the birth, rise, and extinction of countless Transcendental Races, as well as the budding and emergence of nearly all transcendental knowledge and techniques.
Only after fully reviewing this transcendental knowledge, equivalent to the Concealment of the entire world, had Li Si successfully seized that flash of inspiration and mastered Extraordinary Domain Wisdom.
Although, in order to protect Li Si's brain, the World Tree had taken the initiative to erase the overwhelming majority of that transcendental knowledge from his mind, the Wisdom Domain had remained behind. That was the most important gain.
Extraordinary Domain Wisdom was a key—a key of vital importance to Li Si.
Wisdom was an exceptionally mysterious and powerful domain.
