Reincarnated Troll: Use Brute Force to Rewrite the Rules of Another World

There is no female protagonist, development flow, lord, war, or commanding troops. Reincarnated as the lowest-ranking troll clan in the magical world, it has no other advantages except brute strength. In order not to be dismissed as an experience baby by others, the protagonist has no choice but to embark on the road of becoming stronger to protect himself. Using secret techniques and traveling in human society, will he eventually become a vassal of the nobles or a lord who dominates one side?
