Lin Feng was eager to improve his strength. He needed to become stronger than anyone. He was eager to break through to the Ling Qi layer. Only then would he be able to become an Elite disciple. Everybody would be forced to respect his power then.
If he managed to break through to the Ling Qi layer, his spirit would awaken. With his spirits and his mastery, he would become a fearsome opponent.
Exactly like Chu Zhan Peng and Lin Qian whose spirits had awakened. Chu Zhan Peng could fly high in the sky and carry people on the back of his spirit. Lin Qian could control ice and fire by using her universal spirit.
Lin Feng trusted that if his strength and power increased, his spirit would awaken and with his spirit he could increase his strength many times.
Therefore, once Han Man recovered from his injuries completely, Lin Feng would go into closed door training within one of the eight mountains and cultivate hoping to break through to the Ling Qi layer as quickly as possible. He has understood that he would need to increase his strength or he would not be respected in this world.
