NOTE: (This comment was written when I was at manhua chapter 273)
After 10 chapters or so, the mission for Yao Lao will begin...some issues will occur(in the end) but it will be fine as the goal was achieved and there were some benefits after that...
After 30 chapters, the Gu Clan arc will start.....it's a major event, so I am skipping it
After 40 chapters, he will go back to Jia Ma as there will be some sector trying to overturn Yan Alliance......and he will go back to central plains with Cai Lin and his daughter Xiao Xiao(4 to 5 years old).....Yao Lao will decide to personally teach Xiao Xiao and jokes about how Cai Lin was going to kill Xiao Yan if he was not there....she will be embarrassed at this moment...before that he will spend a night with Cai Lin

.....don't know if it will happen in manhua or not.....at this stage he is at Dou Zun eight star(peak)...
After 100 chapters or so, it gets annoying as there was no content that made sense anymore......it just gets repetitive and just goes on.......at this point he will be at 5 star Dou Sheng....
I don't know how it is given in Wiki Fandom but this is just until the novel chapter 1550.
The chapters are pretty much an estimate considering the number of novel chapters needed to make a manhua chapter.
There are many significant events in between and I decided to skip them to not spoil more of course
