Twilight of the Warriors: Walled In

In the golden eighties of Hong Kong, Kowloon Walled City was not only a special zone full of mystery and enchanting charm, but also contained an orderly disorder that was inclusive and integrated diversity. This place gathered many masters hidden from the world who built their own order based on their rules, attracting the masses to flock, but also made people hesitant to approach casually.
Chen Luo Jun, an unfortunate young man, inadvertently found himself here. Fortunately adopted by Tornado, a legend inside the city, he discovered that the actual situation of the city is not as terrible as depicted by the outside world. On the contrary, he was attracted by the order in its chaos and met several fascinating friends, including Shinichi, Shi Er Shao, and Si Zai.
Just when Luo Jun thought he had found a fairly stable place to settle, he heard rumors of outsiders maliciously invading Kowloon Walled City. The big boss who used to keep an eye on the city unexpectedly began to take action, initiating violent fights one after another in a frantic invasion of the city. Everyone, led by Tornado, fiercely opposed the harassment of the big boss, vowing to protect the city that provided them a place to live and establish their lives.
