It is worth mentioning that among all these, the most crucial invention was made by Ye Yiyao.
During the Great Nirvana period, as time progressed, the power of mutant beasts increased significantly. If Ye Yiyao hadn't invented the special technology that could prevent mutant beasts from entering the protection stations, not even Ye Tian would have been able to protect so many people.
Since then, Ye Yiyao has become the Imperial Technician of Huaxia. With her invention, Huaxia has even managed to build four more protection stations.
Moreover, the scale of the protection stations was gradually expanded, and many territories occupied by demon beasts were reclaimed.
Now, only mutant beasts of relatively low levels are active around the human protection stations, as the stronger mutant beasts have been eliminated by Ye Tian and others.
The remaining low-level mutant beasts are used for training new recruits.
