Are You Saying I Have to Win Over Long Aotian's Younger Brother?

[A sunshine-on-the-outside, sweet-but-scheming flirtatious pursuer x a socially anxious, sensitive recipient who constantly rants internally]

When he woke up, Shen Zhiyu discovered that he had transmigrated!

Even more ridiculous, his older sister, Shen Zhimo, had come along with him!

And the most absurd thing of all: the two of them had been bound to completely different Systems!

His sister got the [Strongest System], with a clear goal: defeat everyone and save the whole world!

He got the [Conquest System], with a baffling goal: make the Dragon-Aotian male lead fall for a man... his younger brother, Xiao Jing???

The siblings exchanged a look. All they wanted was to finish their missions as fast as possible and go home.

But what was going on with those two brothers?

They'd said the Dragon-Aotian's younger brother was a sunny, cheerful little softie. So why was Xiao Jing always smiling and sticking to him, calling him "A-Yu"?

They'd said the Dragon-Aotian himself followed the ruthless, emotionless path. So why did Xiao Heng always "happen" to pass by whenever his sister practiced swordplay, casually dropping gear for her?

Shen Zhiyu, a little giddy from Xiao Jing's flirtation, covered his burning ears and frantically thought to himself:

Isn't something wrong with this plot???

Is this really that serious (not really) Dragon-Aotian power fantasy novel?!
