As a Necromancer, Contracting Hundreds of Millions of Dinosaurs Is Not Too Much.

The ferocious beasts invaded, and all the people awakened as beast masters to survive. Lu Chuan was the only awakened SSS-level undead beast master. In his previous life, he had not discovered the characteristic of "the dead get stronger as they age". He contracted a weak skeleton dog and was betrayed and died tragically by the school beauty Zhao Manman. One day before his rebirth, he went straight to the Dinosaur Museum, contracted a 160-million-year-old Tyrannosaurus rex skeleton, and summoned a super-powerful undead Tyrannosaurus rex. His strength increased dramatically, far surpassing his peers who controlled ordinary beasts, and he became the strongest beast master.
