The Book of Life and Death had been slashed, its physical form destroyed. Although the data was saved on Singularity's tablet, that was just a local backup.
To get the entire Underworld system running again, Singularity needed to build a "Central Server" capable of hosting the data of billions of ghosts.
The location was chosen in the coldest place in the Underworld—The Hell of Ice.
Why here?
Because server heat dissipation is a huge problem. This place was a natural water-cooling room.
"The temperature here is constant at minus 273 degrees, absolute zero. Perfect."
Singularity stood before a massive iceberg, directing a group of Frost Demons who had been scared witless by Slayer and were now conscripted as laborers.
"Move it! Pile all that 'Mystic Yin Cold Jade' into the shape of server racks!"
Singularity held his multi-functional whisk, drawing a huge blueprint in the air.
"Heaven and Earth as the board, mountains and rivers as the circuits, Yin and Yang as the Bits."
He no longer used traditional bricks to build; he used spirit stones and runes to construct hardware.
CPU: Singularity found the strongest computing artifact in the Underworld—the "Thousand-Mechanism Plate" (a treasure left by Zhuge Liang after his death, capable of calculating heavenly secrets). He dismantled it to serve as the core processor.
Storage: He utilized the spatial folding technology of "Storage Rings", linking countless micro-dimensional spaces together to form an infinite-capacity hard drive array.
Firewall: This was even more impressive. Singularity directly moved the "Pre-Heaven Eight Trigrams Array" over. Any virus attempting to intrude (whether computer virus or inner demon), if it didn't understand the I Ching, would get lost and crash upon entry.
"This is too hardcore..." The Frost Demons shivering nearby muttered as they moved bricks. They had seen cultivation, seen artifact refining, but never seen anyone building a server in Hell.
The story has been stolen; if detected on Amazon, report the violation.
"Alright, hardware assembly complete."
Singularity wiped his sweat, standing before the crystal ice tower that glowed with a ghostly blue light.
Next was the software part.
He sat cross-legged, his spiritual consciousness connecting to the Heavenly Dao Tablet, and began to "Write Code."
Of course, his code wasn't in English, but in Oracle Bone Script and Thunder Patterns.
if (User.Karma < 0) { Goto(Hell.Level[18]); }
(If user karma is less than 0, jump to the 18th Layer of Hell.)
else { Reincarnation.Start(); }
(Otherwise, start reincarnation program.)
Singularity's fingertips danced, and streams of golden runes poured into the crystal ice server like a waterfall.
Vrrrrm—!
As the last line of code (rune) was written, the entire iceberg server emitted a low hum.
A pillar of light connecting heaven and earth pierced through the dome of the Hell of Ice, connecting directly to the Heavenly Dao.
[System Startup Successful.]
[Name: The Dao Cloud.]
[Status: Online.]
[Coverage: All Three Realms.]
Singularity looked at this masterpiece, tears of excitement welling up.
"It works! Even if the Underworld is bombed flat in the future, as long as this 'Cloud' exists, data will never be lost!"
Just then, Slayer walked over, dragging the corpse of a massive Ice Dragon.
He tossed the dragon corpse on the ground, glanced at the glowing ice tower, then at Singularity.
Slayer walked over, reached out with his gauntlet, and touched the cold server casing.
Zzt-zzt.
The server's indicator lights blinked twice, seemingly saluting this "Physical Security Consultant."
Slayer didn't smash it.
On the contrary, he seemed to think this thing was useful. Because he discovered that as long as he was near this server, the download speed for the tactical maps in his helmet became incredibly fast.
[Map Data Updated.]
[Demon Locations Real-Time Marked.]
Slayer nodded.
This was right. This was the logistical support he needed.
Singularity leaned in with a fawning expression: "Big Hero, this server isn't bad, right? I specially opened a VIP Line for you, max bandwidth! Whenever you need to check where the mobs are in the future, just shout, and navigation will start immediately!"
Slayer patted Singularity's shoulder (almost patting him into the ground).
This was the highest form of praise.
Singularity rubbed his shoulder, but his heart was delighted.
"Entity vs Virtual."
In this instant, the Underworld completed the leap from the "Bamboo Scroll Era" to the "Cloud Era."
"Next, time to deliver the new toys to Daddy Client (King Yama)." Singularity looked at the few jade tablets he had just made, a sly smile appearing on his face.
