Michael was a teenager who had lost everything to the war against the vicious Makisis - his entire family, all of his friends (not that he had many to begin with), and his sense of purpose were all gone. 

At the brink of death, he thought he had lost all hope. With everything that mattered to him gone, there was nothing left to live for. 

However, a mysterious system appeared, offering him quests and missions to level up. He was hesitant for his hope to return but he listened to the system anyway, having no other options.

Blood Monarch System

"Darn it. The system didn't even notify me." Micheal thought as he fell to the ground, bleeding. Zion lunged towards the invisible Makisis almost like it could see it. Blood claws line came out of its claws as it attacked the Makisis. Micheal was stunned that Zion also had an ability related to blood. After all, it was called the Blood Wolf Beast.

Micheal stood up from the ground. He removed the spike from his stomach, and groaned in pain. The deep wound closed up immediately. "This is why i should have filled up my blood saver."  He opened up his stats screen while Zion continued to attack the Makisis.

Micheal had lost 5 hp when the spike hit him. He realised that if the spike were to hit him eight more times, it meant death. He immediately formed a great sword.
