The Undead system - Chapter 19: strange happenings

Keith, a regular office worker from Earth, suddenly transmigrates to the world of the novel he had been reading for the past decade. The new world, which was also called Earth, was slightly different. People with various powers existed who were called awakeners, making this world comparatively dangerous and also mysterious. While he was thrown into the novel’s world, he was also given a mystical ability to grant systems to other people. Armed with his special ability, he slowly climbs up the power ladder by taking “taxes” from the people he would give systems to. The only question that remained, was what would a realistic normal man, when faced with a similar minded protagonist, do when their goals opposed each other.

Wen TianHe originally thought he was a man who’s going to be a domineering chairman. But in the end, he became the man alongside the domineering chairman.

The sharp edge of a knife is difficult to cross; thus the wise man said that the path to salvation will be hard.
—Mao Mu, (Blade)

—Vietnamese Overbearing Chairman, Si Guan (Silence is Golden)
