Dark Magus Returns - Chapter 10: A combination?

The gods visit my shop. I travel across countless worlds with them. But then… “This is my sword, the Heavenly Tyrant Blade.” “This is the Ruyi Jingu Bang.” “This is the lightning spear I once wielded.” Their payments are… peculiar.

Crossing into a fantasy world, Meng Changqing thought he would live an ordinary life, but he unexpectedly awakened a friend system!As long as the other party agrees to become his friend, even if it’s just verbally, he can obtain corresponding attributes from the other party, as well as additional rewards!“Adding the True Legend of the sect as a friend, obtaining attribute: First-class aptitude!”“Adding the Sect Leader as a friend, obtaining attribute: Perfect-level ‘Indestructible True King Art’!”“Adding the dragon girl of the demon race as a friend, obtaining attribute: True Dragon Bloodline!”“Adding the Sword Immortal as a friend, obtaining attribute: Chaotic Sword Body!”“…”So Meng Changqing began his journey of “relying on friends” for cultivation.As for those who are unwilling to be his friends, Meng Changqing can only draw his long sword from his waist and make friends with his noble character.

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

Lu Zhengfei personally killed Chen Qianqing with his abuse.

He cut off Chen Qianqing’s legs, and blinded his eyes, locking him up with chains in his house. Then, he watched with his eyes wide as he died. Injuries inflicted in the name of love would always end in a tragedy.

Did Lu Zhengfei regret it? Of course he did. And so, God gave him a chance to be reborn.

But this time, he found that he himself——became Chen Qianqing.
