Yin is only going to be in this world for a week so she might as well spend all that money that will soon be useless. Blueprints for guns is a good start but she should also get all the science info and blueprints on stuff like factories, power generation or communications she can after all the branwen clan is setting up a network of tributaries in conquered towns and villages and if she gives out any earth science or blueprints the branwen clan gets more tribute from it. She could also pick up all the anime and manga and put it on a hardeive to prepare for the next time she’s sent to another world.
Ojalá la MC lo trate como un hermano pequeño a Hajime ( ya que la fmc es la mayor de todos ) , y una vez llegados al otro mundo , puede encargarse de los que en el original querían matar a Hajime y la fmc tome su camino , dejandolo con su vida tranquila ( y antes que se valla, puede llevarse a shizuko , sería interesante leer como seguirá xd.
