“We live in a world of gliphs. The left arm chamber, right arm chamber, left leg chamber, right leg chamber, wind chamber and the heart chamber. These are the six chambers of gliph that represent a glipher’s quality.”

In his previous life, he was the best metalsmith on the continent; even the most powerful fighters came to him for weapons. He was no doubt a powerful man, but sadly, his incapability to retaliate left him at the mercy of others.

Chui Yim, once dead, reincarnated into the world of gliphs, accompanied by Heaven’s Flame. However, the violent introduction of Heaven’s Flame crippled his heart chamber.

Born with a heart deficiency, he was unable to perform strenuous exercise, let alone engage in physical fights. As such, his father who worked as a doctor made him study hard and sent him to the Riding Clouds Academy, where he met a close friend who was escaping from his family’s mu*derer.

Determined to write his own destiny, Chui Yim vowed to break limits and take up the path of a cultivator.

When Han Kain woke up, he and several other people were inside a mysterious hotel with different rules and different expectations.Going into each hotel room threw them into other worlds and scenarios where they must brace death at times to escape or lift the curse of the individual rooms for a chance to bring everyone that died during the process back to life.Using their blessings that were given at the time of entry, they have to weave their way through the rooms while sometimes sacrificing themselves for a higher likelihood of success.* Very little horror; more of a thriller
