Lin Feng controlled his Steel Tree to follow the Red Dragon King from a distance. While he did not fear the Red Dragon King, it was no easy matter for his Steel Tree Avatar at advanced Nascent Soul stage to hide from detection by the sensing ability of a demon Grand Sage.
Of course, while Lin Feng could pursue the Red Dragon King openly, that would be equivalent to a wolf constantly driving a herd of sheep to run for their lives.
When the Red Dragon King left, Lin Feng vaguely felt that something was not right with its mood. Hence, Lin Feng wanted to find out what trick this old dragon was hiding up his sleeve.
Shi Yu and Liang Pan had some interest in the matter as well. As they had inherited the lineage of the First Emperor and Emperor Tai respectively, they had inherited the hatred between the dragons and the two Emperors of Man as well.
