Taking out the Life and Death Book, Qin Hao poured his World Power into it. The Life and Death Book suddenly opened, and pages flew out.
Each page rapidly expanded after flying out, becoming a white sheet one kilometer in length and width. The strong aura of laws and divine power quickly filled the entire Chaos Ruins.
At the same time, the eight great divine power worlds hidden deep within the Life and Death Book also appeared. The vastness of these worlds and the immense divine power within them astonished Guiyi Venerable.
"This supreme treasure, named the Life and Death Book, has no defensive or offensive capabilities. It is a soul-based supreme treasure, but it offers no enhancement to soul defense or attack. It has only one function."
As he spoke, Qin Hao took out the Wan Shou Tu Pu (Myriad Beasts Diagram), and an Undying was released from it.
"Leave your soul imprint on the page," Qin Hao said to the Undying before him. Although the Wan Shou Tu Pu (Myriad Beasts Diagram) was not used much now, it still enslaved many World Lord Rank and Undying-Level cultivators.
The one released now was just an ordinary Undying, one Qin Hao had enslaved in the Ancestral God Tomb.
"Yes, Master," the Undying said, directly imprinting its soul imprint onto the page. A soul imprint quickly appeared on the page. After it was done, Qin Hao, without any hesitation, swept the Undying beside him with immense World Power. In just an instant, the Undying was completely annihilated.
Watching Qin Hao's actions, both Primordial Chaos City Lord and Guiyi Venerable felt a bit puzzled. However, they were soon drawn by the movement on the page.
Within the page, the soul imprint began to tremble, and a subtle divine power surged from the divine power world towards the soul imprint. At this moment, Qin Hao also activated his World Power, accelerating the divine power's speed. In an instant, the Undying's divine body re-condensed, and its soul power rapidly recovered.
After the Undying regained consciousness, Qin Hao did not continue to draw power from the Life and Death Book. Instead, he directly erased the name from the Life and Death Book and re-absorbed the Undying into the Wan Shou Tu Pu (Myriad Beasts Diagram), allowing it to recover slowly on its own.
"The Life and Death Book has only one function: it can revive anyone who leaves their soul imprint on it. After each soul imprint enters, it will slowly absorb divine power and integrate it into the eight great divine power worlds, continuously expanding the divine power within them to supply the divine power needed for recovery."
"The Life and Death Book has a total of 365 pages, and each page can store 10,000 soul imprints," Qin Hao said, putting all the pages back into the Life and Death Book. At the same time, he used his World Power to float the Life and Death Book into Primordial Chaos City Lord's hand.
"Will it affect the comprehension of laws? Will there be any side effects?" Primordial Chaos City Lord asked. After all, it involved the soul level, and any damage could potentially cause problems.
"No, it only preserves the soul imprint. After falling, the soul imprint will automatically absorb divine power to recover. The soul imprint can be canceled by oneself, or directly removed or annihilated by the controller, without causing any impact."
When creating the Life and Death Book, Qin Hao actually created something more like a 'respawn point' in a game. However, the time wouldn't be as fast, as the recovery time for an Undying's divine power is relatively long. Even with the blessing of the eight internal worlds of the Life and Death Book, it would still take some time.
However, the advantage was that after revival and reaching the stage of conscious awareness, they could directly recover on their own, placing very little pressure on the Life and Death Book.
The benefit of its singular function was that it would not affect those who left their soul imprints, and outsiders would find it very difficult to affect other soul imprints. It was like having a save file stored on a game server, allowing for a rollback at any time.
"Excellent!" Primordial Chaos City Lord nodded in satisfaction after hearing the explanation. Such a supreme treasure had no offensive power and offered no strength enhancement, but for a race, it was a rare and invaluable asset.
After all, even when a Universe Lord revives a powerful being from spacetime, there is a huge cost. There is even a certain risk of falling.
The Life and Death Book was completely different. Soul imprints stored within it could slowly absorb and preserve divine power. After death, they could quickly be revived using the stored divine power. Once they reached a certain stage, they could directly recover on their own.
This meant that the Human Race would have a group of powerful beings who were completely fearless of death, and even needn't worry about the consumption after death. Although the limits were uncertain, even if it was only Champion-Level, such a group of people could directly face Venerables and fight without regard for their lives.
After all, for the various races currently, after a Champion's death, most, aside from those with connections or exceptional talent, would wait for a certain period to be revived. How long they would wait was unknown, and they might even never be revived.
Now, this concern could be completely eliminated. However, selection of candidates still needed careful discernment. The existence of such a supreme treasure must be kept a Lockdown, and only a portion of people would certainly be able to appear on this list and leave their soul imprints.
The time for it to be truly revealed would be when the Human Race faced a genuine great war, only then could this supreme treasure be brought out for the Human Race to use.
"I'll value this supreme treasure at 2000 supreme treasure points. You can freely choose any supreme treasures or materials you need," Primordial Chaos City Lord was not stingy with Qin Hao. 2000 supreme treasure points were enough to freely choose a peak supreme treasure.
In Primordial Chaos City Lord's eyes, a supreme treasure like the Life and Death Book was completely comparable to a peak supreme treasure. He found it hard to imagine that such a supreme treasure could even be refined.
In this Universe, and even the Universe Sea, there were many supreme treasures, and many strange ones existed, but a supreme treasure like this, with absolutely no offensive power, merely serving as an auxiliary tool with a single function—revival—had never been seen before.
Primordial Chaos City Lord even thought about whether Qin Hao, after his strength increased and he became stronger, would be able to refine similar supreme treasures capable of accommodating Universe Strongest and Universe Lord-Level beings.
If so, the Human Race would truly have nothing to fear. After all, once Universe Lords and Universe Strongests were freed from the limitation of being unrevivable after death, they would become even more insane, and the power they unleashed would be even greater.
This was also why avatars became a highly sought-after secret method throughout the Universe. Avatars meant that as long as one avatar existed, other avatars, even if they died, could be revived at any time.
As a peak Universe Lord with an avatar, Primordial Chaos City Lord was also the most difficult to deal with Universe Lord, not even showing the slightest fear when facing a Universe Strongest.
