The Heaven-Ordained Emperor

After transmigrating to an imaginary ancient world, he can’t get enough to eat or drink, while the government keeps raising taxes year after year. Can’t pay? Off to the army with you! They even force people to have children to replenish the ranks. The steppe cavalry are back? The emperor’s been captured again? Another political marriage? The soldiers have all been wiped out? No worries, it’s not a big deal. Watch me conquer the world with math, physics, and chemistry! There’s nothing that can’t be solved.
