Transmigrating to Another World to Build an Astartes Legion

The original owner was tricked by his stepmother and lost most of his family property, so he could only go to the South Continent to inherit a fiefdom. This mess was taken over by the struggling author from Earth who was playing Warhammer.

But he awakened the template of Fugrim, and could also obtain a gene seed every seven days of login! After careful consideration, he decided to build an Astartes Legion!

Sweep across the southern continent, conquer this planet, complete the Great Expedition, unify the Milky Way, and establish a human empire!

Pah! I must have been possessed by a weasel just now.

He thus whipped capitalists while building the Sons of the Emperor's army, becoming the greatest conqueror in the world!
