While his strength was growing rapidly, Lin Yao clearly felt that the most important factor that contributed to the rapid strength increase was not the Heavenly Thunder talent, but the Armored Body Of Light, which seemed to have nothing to do with thunder and lightning.
Among Lin Yao's many talents, the Heavenly Thunder talent was the stepping stone. Light Adjustment allowed Lin Yao to evolve faster, and Project Thunder God was a bright future for him, as it would allow him to reach the end without fumbling.
However, without the Armored Body Of Light, Lin Yao's efficiency would be greatly reduced even if all of the above were available. Lin Yao would only be able to persist for around 10 minutes a day, and he would have to rest for 10 days after each development. It was difficult to tell how long it would take him to reach the end.
