Swordmeister of Rome - Chapter 138

An Individual from Earth finds themselves in the Shinobi World, equipped with a Scientific System. From that moment, he delved into scientific research far ahead of its time.

If a man ‘Levels Up’, any boring work can be repeated endlessly―Natsuno Taiyou.

“Talent” should be useful only in game, but even in reality how is it useful!?

When Taiyou woke up he received a power from a fairy “The ability to Level Up in the real world”, but immediately when leveling up boring work, surprisingly ‘charm’ had dropped down!―However, the charm level that was originally 0, has thank god become ‘65535′!

Taiyou aims to level 100. And enjoy a harem life with seven brides.

The Zhuang Lady sent her dog, Yin Huayue, to keep an eye on him and confine him. She is cold-blooded and hypocritical, and always has a fake smile on her face. Helping him get ready, combing his hair, and lighting the lamps. Awake for twelve hours a day, Li Jingyun spends ten hours thinking about how to make her leave. But after that, she actually left. He became anxious.

Despite our brief time together, we are not appreciated despite our strength. Rather be alone, instead of withering alongside with another.
