The Last Echo of Deep Blue

In 2121, an apocalypse unleashed by the invasion of three races, the insect race, demons, and monsters, swept across the entire planet of Es. The moon vanished completely, and its lunar essence scattered across Es. The alien races had wanted to claim it, but humanity got there first, sparking a full-scale struggle for plunder. Less than five percent of the planet’s population survived, and life was laid to waste. The insect race and demons also discovered that metals and radioactive materials could greatly increase their strength, and began wantonly ravaging human territory. Mo Tianyao and Luo Chengjin had been ordinary high school students, but were forced to endure the countless partings and deaths of the apocalypse. They launched a counterattack, awakening new abilities time and again and mobilizing the resources of the Blue Realm, the plane where Es was located. At last, they struck back against the invaders in the Abyss Realm, determined to bring an end to both the Deep and Blue Realms!
