Konoha's Tag-System Ninja - Chapter 31 - : Sudden Incident!

As a kind of punishment, the wings of a demon king were cut, and he eventually lost all of his power. To get back his power, he made a deal with the angel. He will go to the realm of humans to find a special girl with a special skill who is meant to be her queen. If the woman got pregnant, all of his sins would be forgiven, and he will regain all his powers. But he didn’t think that knowing her would be an adventure for him as the king of demons in the human realm.

The Infinite Survival System suddenly appeared on Planet Blue. Those who are chosen are forced to survive in dungeons.

The Survivors can continue to grow stronger if they survive the dungeon missions. However, just one failure and it would be their deaths.

Every Survivor gets a talent. Some talents can boost the Survivor’s agility, and some enhances their luck, while Zhou Chen’s talent was Passive Plunderer. It allows him to plunder the passive skills of the monsters he hunts.

With that talent, Zhou Chen slowly gathers a powerful list of passive skills.

In the near future, a space channel connecting the other world suddenly appeared on Blue Star, and a large number of other world monsters poured into the homeland where human beings depended for survival.

Human civilization has shrunk sharply and had to hide in the base city to survive.

Only warriors can lead human beings to open up living space and regain lost land.

However, martial arts requires talent, and not everyone can become a martial artist.

People with outstanding martial arts talent can not only advance quickly and break through limits, but also optimize their exercises and benefit future generations, and are admired by all mankind.

By chance, Lu Heng discovered that his martial arts talent could continue to evolve…
