Kuma Kuma Kuma Bear - Chapter 164: Bear-san Receives An Invitation

An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.

I’m an imperial uncle; his imperial majesty’s uncle.

Once, someone with nothing better to do took a comprehensive survey of the current dynasty, and summed up the imperial court’s three great cancers.

Wang Qin leads in corruption; the treasury is never full.

Yun Tang favours a few, forming cabals; leading to corruption in our politics.

Prince Huai plays with power, and serves as the head of a hundred poisons — thus causing instability to the throne.

When they talk about the most venomous of vipers, the wicked one who plays with power, the biggest cancer of them all, they’re talking about me: this insignificant prince, Prince Huai, Chengjun.

I can only say that I feel rather hapless in the face of these theories.

In truth, I have been ever dutiful, ever devoted, devoid of intention to monopolise power, and possess even less of a heart to covet the throne. In the entire imperial court, I dare say there is no loyal subject more loyal than I.

But, most tragically, in all the realm, the matter of my being a loyal subject is something that not many would believe.
