Lao shan lung

The first shen gao ren I think is at the transition from hr 3 - 4, it's an urgent at the guild hall so yea have fun, I'm not sure about lao but hey! Life's good

You keep chopping at his legs until they change coluor TWICE on EACH legs.
U fight him wen you do rothals blue ratholas rathien pink rathien doblos ratholas+rathien kirin

I answered your q with awrong answer sorry.
To kill a loa shan you jut start chopping at him
Jump on his back carve nd use anti-dragon bomb
Also use balista nd spikes wen close
Also bring acannon ball to shoot him with wen hes on his way to the fort NOT wen hes at itor you will miss

You can beat a lao shan lung earlier than the Hr4- Hr5 transition by beating all the 3* and 4* quests and unlocking the red lao shan lung. The one you fight in the transition from Hr4 to Hr5 is the ash lao. When fighting Lao the safest place is it's head but doesnt cause the most damage. While using a far range weapon shoot at it's back to cause most damage. When using a melee weapon attack the stomach to cause most damage, but if you want to stay safe attack the head. When you make it to bridges where you can get on top of them jump on it's back for a few carves and use the anti-dragon bombs located in the supply box. When you reach the last area use ballistas that can be found in the supply box and on the ballista rack in the base. I don't really reccomend cannon balls because you can probably do more damage after youre finished shooting the ballistas than waiting for it to get close enough to use a cannon ball. When Lao stands up climb the ladder, back up the where you shoot the ballistas, and there should be a button click "O" on it when lao gets closer and you will have used the dragonator to hurt him. To unlock elder Shen Gao Ren you need to beat all the monsters in the game twice not including Fatalis, Lao Shan Lung, Rajang,Shen Gao Ren, and Akantor.
