Hong Kong Movie: with Explosive Soldiers, I Become a Troublemaker

Gu Yan inexplicably traveled to the world of Hong Kong and is neither a policeman nor a gangster! Just a low-class person. Fortunately, there is an explosive system. Elite soldiers, special forces members, and weapons and equipment can all be purchased with money. What would he do in this situation? I'll see if I can make money. If it's more, I'll switch to writing. If not, I'll try to finish this book! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
