Seventeen Again: The Sweet Life with My Family - Chapter 637 - Qualified Mrs. Shen

I am Lin Fan and I’ve become a jack of all trades just because of a powerful Encyclopedia.
In the first ever competition organised for trolls, all the other contestants lost. The crowd exclaimed, “Brother, you’re so good at trolling.”
Lin Fan replied, “But I’ve never been trolling…”

Welcome to Freia. A continent where evil magi ruled. Until firearms came, that is. Now the people live free of those demons…

More, however, must lurk beneath the surface.

Claude, a transmigrator from another world, finds himself in the midst of this changing world, attending ‘middle school’. Or, as he calls it, ‘boot camp’. His destiny was to graduate and join the military, but the future is seldom so simple.

His life, and the world, is set on the path of upheaval and chaos the day he finds a cookbook.

A magical cookbook.
