The Soul System in the Apocalypse - Chapter 24: System Upgrade Function

When The Cute Kunoichis Spied on Their Teacher's Secret is a light novel written by Kazuma Kamachi and illustrated by Ryuushi Tajima.

The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

A series of nine stars occurred here, and various creatures violently mutated, killing the former overlords – humans crazily.

Thermal weapons are no longer humanity’s trump card.

Fortunately, mutations have also occurred in humans.

Human beings will awaken their bloodline at a specific time and gain the inherited power of various ferocious beasts.

And Xu Mo, who obtained the system, was even more outrageous.

He awakened the bloodline of the ten ancient beasts and led mankind to regain its dominance! !
