The Six Prefectures of Zhongbo were ceded away in surrender to the external enemies, and Shen Zechuan was taken into custody in the capital, reduced to *a drowning dog loathed and condemned by all. Xiao Chiye followed the scent of the furor and made his way over. But instead of setting others on him, he kicked Shen Zechuan with his very own leg that rendered the latter an invalid. Who would expect this invalid to turn around and bite him in a counterattack until he was all drenched in blood? That was the start of an epic feud between both men who tear at each other every time they come face-to-face with one another.

“Fate wants to bind me here for life, but this is not the path I choose. The yellow dust engulfed my closest kin whole. I have no wish to bow in submission to an illusory fate. The imperial edict couldn’t save my troops, and the imperial court couldn’t fill the stomachs of my mounts. I’m no longer willing to lay down my life for them all. I want to conquer that insurmountable peak. I am going to fight for myself.”

1v1, HE, HE, HE.

◆ Main Couple: Xiao Chiye (gong) x Shen Zechuan (shou)
◆ There’s a yuri cp that are both important characters.
◆ Gong is even more of a scoundrel than the various gege in the author’s earlier novels.

Note: a drowning dog is someone who is down and out having lost favor or power.

- Description from Novelupdates

My disciple, whom I raised and cherished with my whole heart…That same disciple has returned and is trying to kill me.“Before you fall, before you cease to be my idol, my hero, my sun, I will kill you with my own hands. For your honor!”Just wait for a while…I’ll bring you back to your senses.

“….Krische-sama, are you not afraid of killing people?”

“……? No. After all, it doesn’t hurt Krische.”

Although gifted with the talent to do anything with ease, the girl lacked empathy.

In her world, there is only loss and profit. No goodwill, no love.

Inhumanly recognizing cold, mathematical logic as everything, she looks at everything in the world through calculating lens.

Return given profit with profit, loss with loss.

The girl was undoubtedly pure, yet undeniably abnormal—

Her favorite things are cooking, food, and being pampered.

Her specialty is mu*der.

—- This is the story of a slightly unhinged girl being surrounded by kind and loving people, and her journey to find happiness.
