At noon the next day, when the rare warm winter sun shone throughout Los Angeles, Chu Nan and Tahm Kench walked out of the research room.
Tahm Kench's face was weary.
From receiving Chu Nan last night and accompanying him to do experiments overnight until he stopped earlier, it had lasted for eleven hours.
Even if he was a fifth-stage Internal Breath Martial Artist and had much more stamina and energy than ordinary people, he was still exhausted.
However, his eyes still revealed intense excitement and satisfaction.
Although he had only cooperated with Chu Nan for less than half a day, he had already obtained a huge harvest.
Not only did he observe the immediate change in a martial artist when cultivating different Internal Breath cultivation methods from Chu Nan, it was far more obvious than on other experimental martial artists.
