Journey to the West: Sun Wukong's Advice System - Chapter 802 - 495: Exposure

Based on the popular Vocaloid series, by HoneyWorks, called “Kokuhoku Yokou Renshuu (Confession Rehearsal)“:

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

Facing extinction, humanity seeks salvation in the Astral Verge, a dangerous dimension accessed via portals that threatened to wipe out the entire planet.Few years later, aspiring recruit Daniel Vance enters the Verge for his final assessment, hoping to Awaken a Talent and secure his future. While others gain common abilities, Daniel secretly Awakens the mythical SSS-Grade Talent: [Soul Assimilation]. This allows him to absorb essence, enhancing gear, gaining stats and EXP from slain creatures, and crucially, absorbing attributes and skills from fallen Awakened.Witnessing the swift death of the arrogant Jaxon Rex, Daniel makes a grim choice: he assimilates Jaxon, gaining his first skill, [Kinetic Pulse]. This sets his path: scavenging the aftermath of others’ battles. He enhances gear and, after achieving his first kill on an injured beast, waits patiently to assimilate two more fallen recruits, acquiring [Quick Step] and the invaluable passive [Aura Sense].Starting as average, Daniel rapidly gains power in secret, enhanced gear, multiple skills, and boosted stats , far exceeding his peers while remaining outwardly unremarkable. He navigates the lethal Verge alone, using its inherent dangers to fuel his growth, wrestling with the moral cost of his unique, overwhelming power.

I accidentally changed the whole world, the resurrection of the dead, genetic variation, recovery of the qi, mountain and seas reborn, land and seas expanded and evil spirits have started to appear.

Ghosts are now commonplace. Some people now have three heads and six arms. Some people have obtained martial arts techniques and ordinary people are now just cannon fodder.

Fortunately, I have acquired an ability which can make various items mutate.

books into martial arts or cultivation manuals,

fruits into precious treasures of heaven and earth or poison that you can only imagine and…

weapons, that can split the earth or gain sentience!
