Ju continued, "Aside from the Heavenly Candle, there was also a breakthrough in a special field."
"Building on the [Death Symbol], Miss Hela created the [Death Tablet], which can be applied in actual combat. It drew from the [Certificate of the Dead] issued by the rulers of [Autron], Theresia's world, which gave Miss Hela inspiration and direction."
"Originally, Miss Hela wanted to explain this technological development to you herself, but during wartime, she was eager to develop new usable runes, so she asked me to do it in her place."
Two labels popped up above Ju-form Star's head.
[Death Tablet: Undead Passage], [Death Tablet: Undying Puppet Shadow].
Lu Yao clicked the first one.
In appearance, it looked like a black crystal panel.
[Death Tablet: Undead Passage]: Opens a passage to the Underworld for a short duration. Usage requirements: Dead (0/5) World Stone (0/40000)
Ju said, "The Death Tablet uses the Black Wall as its carrier, with the Death Symbol printed onto it using the Dark Element. Using it does not consume the dead; they are only needed as mediums."
Five gray ghosts appeared beside Star's Shadow.
All the prerequisites had been met.
Lu Yao invested the full amount of World Stones into the tablet and clicked the mouse.
The crystal panel glowed, projecting a red gate of light into the void.
Ju explained, "This is the Undead Passage. It can enter the Underworld, but due to current technical limitations, it is a one-way passage."
Lu Yao understood.
This was an improvement on Odin's death rune.
He looked at the next one.
[Death Tablet: Undying Puppet Shadow]: A puppet shadow created with the Death Symbol. It can synchronize consciousness with the dead through the Law of Death. After the puppet shadow disappears, the dead one's consciousness will return.
