Genshin Impact: A Snezhnayan Technician and Herrscher of Reason

[No Harem] [Puppet] [Herrscher of Reason]

Lu Jianwei transmigrated to Teyvat with only a Herrscher of Reason Core. He didn't want to be a savior. All he wanted was to quietly coast at work in the Fatui's military-industrial system, do some experiments, and practice close-quarters combat.

However, everything he made turned out to be more profitable than the last, and the Regrator promoted him, assigning him to work with the Doctor for twenty years. At long last, after that troublesome man was gone, he was transferred to Sandrone's team. He thought he could finally draw up blueprints in peace, but on his very first day, she caught him in the act.

"You call this a weapon?"

Obviously. It can defend, attack, and even take down your clockwork creations. Of course it's a weapon.

Unfortunately, a high-output test missed a linked component, and he got the harshest dressing-down of his life from the Armory Palace. When a girl's voice rang out at night, the Marionette slammed the door in irritation, while he sat by the window, listening with great enjoyment.

Behind what looks like an ordinary working life lie secrets spanning two hundred years, a storm brewing across the seven nations, and two Harbingers who are not to be trifled with.
