Can one man, armed with the knowledge of two worlds, avert a catastrophe and carve out a new destiny?Prepare for an epic tale of innovation, mystery, and survival in a world where the past and future collide.

In the third year of the Kaihuang era, as the Great Sui began to unfold between the fall of the Northern Dynasties and the rise of the glorious Tang Dynasty, Emperor Yang Jian created the House of Blades – an intelligence agency for strategies and conspiracies – in preparation to unify the world.

On a snowy night, a convoy of tribute from the Kingdom of Khotan was raided. Not one soul survived the attack. Feng Xiao, Second Commandant of the House of Blades, was ordered by the Emperor to investigate the matter in person.

On the distant border, a storm brewed as major forces gathered from all sides in Liugong Town. The strong rubbed shoulders with the strong; the skilled crossed paths with the skilled.

Here, the ever-successful Second Commandant Feng ran into a wall for the first time – all because of a feeble Taoist priest with ailing health.

Some things would never be known if no fights were ever picked. Only through their skirmishes did Feng Xiao realise that this sick bastard seemed to have way more aliases and personas than he himself ever did.

In the Interstellar era where the strong are king, soft and cute species are almost all extinct.

Tu Mianmian, who crossed over, was given a ruthless Duke husband, a husband who could destroy Mechas in minutes.

As a lop-eared rabbit who had just refined his human shape, he felt weak, pitiful and helpless.

So, he resolutely ran into the entertainment circle, relying on his sky-defying appearance to garner large amounts of fans from interstellar society, including his own gong/husband.

It was night, and the Duke who was going to improve the relationship between husband and wife walked to the door and saw a fluffy lop-eared rabbit lying on the sofa…

When Tu Mianmian found himself sleeping beside his gong with his rabbit body stretched out, he scared himself. Sitting up in shock and dazed, he unconsciously stomped the Duke’s mouth. Shivering, he retracted his rabbit paw, but was caught by his gong with a cold face.

Tu Mianmian: …I, I, I am willing to cut off this rabbit’s paw!

Before he could finish speaking, the iron-blooded Lord Duke approached his mouth at the speed of light: Chuu~~ ( ˘ ³ ˘)♥
