Naruto: Kurotsuchi Mayuri - Chapter 19 - 12.1 : Konoha Hospital!!

Qinghe County master Gu Sheng died. She had a first class beauty, her name could move the world, but she still lost to the hands of a woman inferior to her. Gu Sheng was only able to understand that she was the antagonist of the heroine after her death, a cannon fodder.

In a pure white space, Gu Sheng was expressionless because of the transmigration.

System: “The heroine must change her fate, must fight against cannon fodder and the passerby to brush a sense of existence. As the master, you are their biggest stone in the way.”

Gu Sheng’s eyes flashed and made a peerless smile, “Then let me see who is the stumbling block that should be trampled and who is the final winner!”

Akira Kuromiya is just an average high schooler who gets killed by a robber. He wakes up and is now a chicken!? Even worse he becomes the familiar of a girl who's apparently the heiress of a powerful clan.

That was for a short while though, as he was abandoned and woke up to find out he, now she, is trapped in a deadly magical forest with all sorts creatures trying to kill her.

The world she finds herself is one of magic and monsters like the manga she's been reading. Akira, now Hinotori is trying to live her life as a chicken in another world!

This was the apocalypse. Humanity was at the brink of extinction, all resources were exhausted, and the entire world was in ruins.

Just then, enormous, mysterious black towers appeared in various locations across the globe.

Inside the towers, there were huge amounts of resources. The greater the number of floors of the towers, the more resources it contained. However, corresponding to that, there were also more powerful beasts protecting them.

The only way for one to obtain what he desires is to become stronger and defeat them.

As such, at the demand of the Global Federal Government, teenagers who are of age have to go to the towers to awaken their talents.

Liu yan, who had transmigrated here, awakened the SSS-rank talent: “God-tier Extraction.”

Extract the impurities, and increase the power level of his equipment.

Extract the beasts, and obtain resources to level up.

Until one day, he realized that he could extract the stats and talents of other people…

This marked the beginning of Liu yan’s journey of endless harvesting.
