Because the plane sent by the Chen family was not arriving in New York for three more days.
Lin Fei decided to take this opportunity to infuse the power he absorbed from Zong Guoyao, Martial Saint level four, into Ruyan and Chen Xinyi.
Chen Xinyi only had the strength of a Master, while Ruyan had never practiced martial arts.
Originally, infusing power into Ruyan, who had no martial arts skills, would take several months.
However, time was not on their side, as the plane from the Chen family would arrive in New York in three days.
Hence, Lin Fei had to complete the infusion of power to Ruyan and Chen Xinyi within these three days.
To ensure the successful infusion of power into Ruyan and Chen Xinyi, Lin Fei had to use his mysterious strength.
For three days, without rest or sleep, Lin Fei used his mysterious power to infuse the energies absorbed from Zong Guoyao into Ruyan and Chen Xinyi.
