If he cut off half of his strength to create an avatar, this new avatar would be very strong from the very beginning. He didn't need to cultivate from a young age. Furthermore, once an avatar in the loose life form controlled a world like Dao Domain Sunflower Head, it would grow up very quickly.
As for his original body, although his strength had been halved, he didn't lack resources at all. If he cultivated the Supreme Divine Technique and the Godfiend Formless Technique at the same time, he would definitely return to his peak in a hundred years.
Anyway, the human race was still in the Chaotic Wasteland, and with the existence of Fifth Senior Brother here, it could be said that the human race were absolutely safe. By the time he left the Chaotic Wasteland, he would have long recovered his peak combat power.
