A Hentai System in the World of Danmachi - Chapter 154 - 153 - Rivira.

When Fang Yuan was transmigrated into a world where Gu Breeder was the main profession, he found that he was not gifted.

Not only that, the Gu in his body could cultivate on their own.

[Your Iron Skin Gu has trained profoundly and has achieved the Gold-grade!]

[Your Bloodthirsty Gu has begun to multiply itself into a swarm of Bloodthirsty Gus!]

[Your Sunlight Gu has been absorbing the power of the sun for years and has gathered the Truth Flame of the Sun!]

[Your Drunken Gu has evolved into a Soul-reaping Gu. Your control over it has risen by 100 folds!]

[Your Flying Sword Gu was hurt in battle. Amid its desperation, it has evolved into a Sword God Gu!]

“Heck, even Gu undergoes involution as well now?” Fang Yuan let out a sigh.

Ji Yuan transmigrates to a Cultivation World, and although he is lucky to become a Cultivator, he ends up serving a Cultivation Sect as a Fisherman.Given this start, he thinks he could only tread the path of a servant.Unexpectedly, he awakens a building upgrade panel.【Fish Pond lv1: Fish fry growth rate +20%, a certain chance for half-spirit fish to evolve into Spirit Fish】【Cave Mansion lv1: Self-healing walls, basic Dust Avoidance Barrier, nighttime Spiritual Qi concentration +20%】【Chicken Coop lv1: One Spirit Egg per day, containing a trace amount of Spiritual Qi, allows Fasting】【Pigsty lv1: Spirit Dolphin gains 100 pounds of muscle in seven days, the flesh contains Body Tempering Medicine, and can accelerate wound healing】【Spirit Field lv1: Crop cycle -30%, output contains weak wood Spiritual Qi】

When human beings ventured into the Interstellar Age, they encountered the Ochs Civilization, and thus followed the first Interstellar War.

Lost territories continued to increase along with the skyrocketing casualties. Eventually, humans were forced back into the Solar System.

In the 58th year of the Federation, Lin Fan, a traverser from Earth, graduated from the Interstellar Military Academy and entered the Federation Fleet.

That then signalled the day of the humans’ counterattack!

From dominating the Milky Way to the entire Universe, mankind never stopped.

This is a story of a traverser leading mankind to rule the Universe!
