How Did the Great Sage Become Accomplished?

Yuanwu Continent is full of hundreds of tribes. Whenever mankind faces the crisis of annihilation, a group of people will stand up to guard the last fire of mankind, and these people are called great saints. My name is Song Yuanming, and I am particularly happy to be one of the many time travellers. On the continent of Yuanwu, people there cultivate a kind of magical energy, which is very powerful. I couldn't beat them at first and was often bullied. Fortunately, I got the sacred tree later. With the help of the sacred tree, I eliminated all the bad guys, and in the end I became the Great Sage inexplicably. OMG! Is it that easy? If you want to know my story, please collect it and watch it.
