The System Has Gone Mad and Insists the Modern World Is Primordial Chaos

Ding! Host detected under attack by a swarm of first-tier prehistoric beasts, blood-sucking mosquitoes. Life in immediate danger. Prehistoric Sage-Ascension System successfully loaded.

This System will help the Host survive in the exceptionally perilous prehistoric world until becoming the supreme Sage.

Main quest issued: Expose the demon spy among the five people in the dormitory. Reward upon completion: Innate Spirit Treasure, Five Elements Banner.

Early in the morning, Lin Fan was bothered by mosquitoes. He slapped at them, but not only did he fail to kill them, their numbers grew.

Just as he was getting frustrated that he couldn't swat them dead, he unexpectedly awakened the Prehistoric Sage-Ascension System.

Seeing the lavish reward for the main quest, he immediately hung his roommates up and beat them for three days and three nights, trying every one of the Ten Great Tortures of the Qing Dynasty. Yet his roommates still refused to confess. They must be highly trained spies, so he would have to keep torturing them...

Surely the System hadn't gone crazy and mistaken the modern world for the prehistoric one?
