The two tribes had resisted before, but the old Tyrannosaurus king was very wise, and with the powerful Devil Tyrannosaurus Legion, he broke the backbone of the two tribes. For thousands of years, they could only linger under his terrible rule.
If the Tyrannosaurus king had not died suddenly, they probably wouldn't have even retained the consciousness to resist.
However, even so, it was not very smooth, and the two young clan leaders could only lead a group of young people and their Demon Dragon partners to initiate a surprise attack. Demon Dragons, a variant of Devil Tyrannosaurus, could fly, but had relatively thinner bodies and were partners that the two tribes could domesticate.
Under the desperate fight of the young people from the two tribes, they annihilated several Devil Tyrannosaurs vying for the throne. The ordinary Devil Tyrannosaurs were not very intelligent, and without the high-intelligence leader, they instantly scattered.
