Chen Ming continued to follow the man once again. He didn't know what he was about to gain from this, but at the very least, after a few more days, he finally realized why Liu Song was so strange at every turn. Why the man seemed to be extremely human and another second a person with extreme vigor.
One simple word: Liu Song probably had multiple personality disorder.
Of course, Chen Ming couldn't be sure because he didn't get to interact with the Emperor other than a handful of times, which wasn't enough really.
Thus, he decided to continue to follow the man at the same time, he started learning the martial arts guidebook that the system gave him along with the weapons. Although this guidebook seemed ordinary, there was nothing around that. With every turn, he was able to experience those moves just like that without even having to practice it.
