Isekai Yururi Kikou ~Raising Children While Being an Adventurer~ - Chapter 327

In the interstellar era, the starry sky group came, and human beings stepped into the starry sky, opened the door of psionic energy, and stepped into practice.

Jiang Chen pushed open the door of psionic energy, but he felt that there was something wrong with pushing it open…

Your body has awakened the [Toughness] skill, which is strong and resilient.

Your bones awakened [hard], the opponent stabbed your body with a sword, and the long sword was broken by the bones.

Your hair has awakened [fork], and the sword qi has been divided into thousands, and the net is spread.

Your stomach digested a panacea, awakening [digestion], endless spiritual energy, and instant digestion.

Until one day…you awakened the [Perpetual Motion Machine], the heart kept going, and the power kept going.

Years later, you realize in a trance that your body is already on par with gods.

He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

While a certain young man hides in a certain Ruins City, wanting to become a tanky mage through passive farming.

Mages should focus on learning more spells and magic? There is no time to invest in body strengthening? Mages are defenseless when they run out of mana? None of these are a problem for Gurney and his Passive Farming System. Through the system, Gurney trains both his body and mind at the same time, he goes beyond the limits and logic of an ordinary mage. This is a mage who casts spells while tanking hits, his recovery speed surpasses even warriors and knights. This is the journey of a vigilant and careful mage who grows tankier and tankier.

…

With the rising waves of darkness, the steampunk steel ship sets sail on a journey and adventure.

Whales sink to the depths of the sea, sirens sing with beautiful voices, calling out to the Transcendent sailors who hunt for mermaids.

The mysterious Time Hunters who obey the ancient rules search for their prey.

He who bears the title of “Hero” carries the burden of fate as he steps on the road to write a new page of history.

Ancient “Sealed Ones” rush to break out of their imprisonment, wanting to create and release new “Supernatural Memetics”.

The combination of steam technology and supernatural powers bring forth the era of “Transcendent Genetic Warriors”.

Infant dragons who have just hatched watch as the Dragon Slayer digs out their mother’s heart from her body.

Calamity level lifeforms sharpen their blades, stepping into the stage of this extraordinary era.

The tides of the era surge and swirl, bringing along the mysterious fog of darkness…

The indescribable existence nurtures and grows…

Along with the stare of the Abyss…

Every drop of this family bloodline is stained with sin. They are the embodiment of contradiction; calm yet maniacal, with great memories yet often forgetful. They pledge themselves to their dreams yet often compromise, are angels that are also devils… It’s why I hate them. And also love them.
