Warming up???
Song Kunlun's words directly left the spectators in the lab dumbfounded.
Such a thunderous, lightning-like punch was merely a warm-up? Could it be that their boss got knocked senseless?
But Song Kunlun's subsequent actions made it clear to them that he wasn't knocked senseless; it really was just warming up.
Song Yun's foot was still held by Song Kunlun.
After Song Yun delivered that last punch, his entire strength, like a flowing river, drained away in an instant.
This is a period of emptiness after exerting all one's strength, which always requires some time to recover.
At that moment, Song Yun was just like this, his strength rapidly recovering, but Song Kunlun wouldn't foolishly wait for him to fully recover.
Of course, now it didn't even matter to Song Kunlun whether Song Yun's strength fully recovered or not.
Song Yun's thunderous rain of punches, though they reddened Song Kunlun's skin in waves, didn't hurt him at all.
Not a single injury.
