Lin Huang did not waste time the days after the New Year.
In order to get Bai, Tyrant and the rest to learn human combat skills faster, he took an entire day to talk it through with Bloody and Grimace. They eventually came up with an idea.
Lin Huang got Bloody to collect a massive amount of combat skills as its database, analyze the core composition of all combat skills, extract them and merge them into combat skills that were suitable for Bai and the rest.
The reason he wanted to spend so much time doing this was that it took a long time to learn high-grade combat skills.
Even an immortal-level human powerhouse who was talented in Sword Dao would need at least a year to master a legendary-level sword skill perfectly.
Lin Huang's ability to learn one sword skill an hour did not come from his talent but from the cheats that he collected.
