The Extra's Survival: Logging into the Game Master System! - Chapter 149: [Angel of Light!]

For He Gu, to be secretly in love is like a strong alcoholic drink. Obviously, once it flows into your system, dizziness, the loss of self-control and suffering will follow closely by, making it possible for anyone to be fatally attracted like moths to flames, and willingly endure the hardships.

While you made sure to not overdo it, I’ve become completely intoxicated…however, for every intoxicated feeling, you will inevitably wake up from it one day.

When Song Ju Han continued to act childish and recklessly destroyed He Gu’s tenderness for him, he had never imagined that the man has already been written into his destiny. Even more, he had never imagined that—the person brought to him by destiny—would one day want to escape…

This is a world where humans, demons and mysterious beasts coexist. Humans cultivate mysterious qi. Demons cultivate corporeal bodies. Mysterious beasts cultivate soul perception. A legend says that in the middle of an endless rainforest, there are extremely powerful existences; they are called demon kings. Some demon kings have a tyrannical corporeal body, some are experts in illusions. Some demon kings are proficient in magic, some can even move mountains. Some demon kings are able to sense things thousands of miles away. These demon kings rarely appear in the human world. Even if they emerge in the human world, they would reincarnate in human form; assimilating with mankind while seeking to breakthrough realms…….

In short, MC inadvertently created a world, but as the creator of the world, he did not know the world at all. He should have lived here like a fish in the sea with some plug-ins that MCs always have. But now he is even stumped by the bugs in the instant world. Luckily, in this world he has found his shadow guard, or his lover? So the daily adventure is getting not so boring…

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.
