After returning to the vice city lord's residence, Ye Qingchen went straight back to his quarters and hung a "Not Receiving Guests" sign on the door.
With two to three days left before departure, Ye Qingchen had no friends in Northern Barrier City worth saying goodbye to. He had already met with Liu Wan'er, so he decided to spend these few days consolidating and integrating his knowledge of formations.
Having just broken through to the second layer of the Martial King Realm, it would be difficult for Ye Qingchen to advance further in a short time without a fortuitous encounter. As for alchemy, he seemed to have reached a threshold, and it was not a pressing matter at the moment.
Conversely, formations were now the quickest and most effective way to enhance his combat power.
Although he had been studying for a long time, his attainment in formations was still at the level of a First-Grade Array Master. This was only because he had never been exposed to formations before.
