Review Detail of Jynxieee in Heaven Smiting God Emperor

The mc is from a smaller kingdom and there a thousands strimger than it but the mc is able to destroy an wntire mountain at the age of 12. And the thing is he isnt the only one that can do it. If it was that easy to destroy a mountain there wouldnt be any left. The power ranking make no sense at all.( I only read to chap 8 tho)
