Although Shen Tian had grasped numerous new forms this time, he still decided to keep as many hidden as possible. He definitely would not reveal them all since the cultivation world followed the survival-of-the-fittest mindset. He had a higher chance of survival, the more trump cards he concealed.
If one displayed only battle prowess of the Foundation Establishment stage, then a Golden Core cultivator's powers would be enough when they encountered dangers.
If Shen Tian revealed all of his strength, then once someone targeted him, it would be catastrophic for him.
After this experience in the Fog Plain, Shen Tian had understood the importance of the strategy to be steady and hide one's weakness even more. If he were given another chance, he definitely would not take the risk and come look for treasures alone.
Shen Tian ate the delicacies, so he sorted the benefits he had reaped and prepared to leave.
