Heaven and Hellfire Compiled - Book 2: The Heir of Kings

Qin Chen crossed into Taiyi Holy Land as a sweeper, and at the age of sixteen awakened the system. As long as he signed in at different places, he could get different rewards.

Sign in at the Land of Emperor Ruins and get the world’s No. 1 Chaos Holy Body and the Chaos Emperor Sutra!

Sign in to seal the magic land and get the quasi-emperor soldiers!

Sign in at the Refining Hall and get the God-level Refining Technique!

Sign in at the medicine garden and get the medicine of immortality!

Sign in at the Imperial Palace and get the Emperor-level forbidden magical power ‘Resurrection from the Dead’!

…

Qin Chen thought that he would just sign in silently until the world was invincible.

One day, the relics of the Great Emperor will appear in the Holy Land, all the holy places, families, and ancient dynasties have come, and there will be an unparalleled demon king in the relics, killing countless powerhouses, ruling the world, and wanting to destroy the Holy Land.

In desperation, Qin Chen could only walk out, slapped the Demon King to death, and sighed: “I just want to be a sweeper and sign in silently. Why do you force me to take action?”

The Interstellar Fleet from the game appeared before the ordinary youth, Bai Zhongqi, and the player became the Chancellor of the Empire, opening a new chapter for his brethren and Earth as they set out for the vast sea of stars. The nations of Earth were engaged in cunning and fierce competition for the future of the Intergalactic Era. Bizarre and varied alien civilizations were waiting for Earth’s explorers to discover them. It was a cruel, dark jungle where only the fittest survived, and a world filled with opportunities and magnificent adventures.
