Back to Field: The Master Mechanic

I'm looking for a book in which the protagonist travels through time and becomes He Jiong's younger brother (who seems to be) suffering from smiling depression. Does anyone know the name of the book? Thanks

(It's so interesting! Is it fun to troll Cai Xukun every day? ) You guys, You just don't understand anything and you're just pretending! Kun fans just like Cai Xukun and think Kun is the best at basketball! Kun composes and composes his own songs, can you trolls do that? OK? (No, get out! Also, Kunkun sending a lawyer's letter is legitimate protection, isn't it? ) (This is justice! You trolls are uneducated and still go around making trouble. What is this? ) (This is simply embarrassing! Even if Kunkun is not good at basketball, he can still be on TV shows. ) (It's so nice! It's great! You trolls can only blindly troll and troll on your mobile phones. ) (Really disgusting! Kunkun has fair and tender skin, red lips, big eyes, and a pretty nose. ) Kunkun is awesome! If you dare to criticize Kunkun again, (come here to read, I am an ally)

360-Degree rainstorm and pear blossom needle, are you ready to die together? Kill yourself too

The protagonist's golden finger has nothing to do with entertainment, so why is he licking it like Haba*?

After reading this introduction, I understand that the Heavy Rain Pear Blossom Needle is a hidden weapon that kills the enemy together  **fires at high speed haha

Can a wooden man still dive into the sea? Make one and let me see! Elementary school students all know that wood has buoyancy, and it's almost as good as crossing a river!

Whether the world is in chaos or not, yearning has the final say Yuanfang, what do you think?

After reading dozens of chapters, I feel that Xiaohong is the protagonist.

First of all, some common sense. What is a mechanism? If you make a pile of wood move by itself and have its own thoughts, artificial intelligence is not as good as you.

This novel is still being written
