Song Xiaodong originally thought he could recover somewhat in two days, but his injuries turned out to be far worse than he imagined.
Over these two days, aside from eating, he focused entirely on trying to restore his meridians. However, the damage to his meridians was extremely severe; after two days, he had only managed to recover a little. He could now return to the level of a normal person, but as for his former strength, it was out of reach. Even dealing with two big men at this point was something he had no confidence in.
Of course, if Song Xiaodong were to resort to killing, then his current physical state would be sufficient. Killing someone doesn't necessarily rely solely on inherent strength; there are plenty of techniques. Song Xiaodong had honed his skills on the battlefield for so long that, if he wanted to deal with Cao Heyang and the others one by one, it wouldn't be a problem.
