After its upgrade, not only did the system interface became more refined, its functions were more advanced, too. Now, when Zhao Yu tapped on the hexagram poem, there would be a pop-up with numbers that represented information about the direction, distance, and time.
In other words, Zhao Yu didn't need to spend any effort to resolve the side quest. He only needed to make a comparison on the map, using the chunk of numbers.
Besides, there was also a new function on the device bar. This was the "strengthen" function, which he couldn't tap on previously, which had now been finally activated.
Zhao Yu tried it and realized that strengthening the device really required a large amount of accumulated points. For example, if one wanted to strengthen the Invisible Bulletproof Suit, it would require to more than eighty accumulated points!
