Aside from not being able to cultivate the perfect Ice and Fire body, Lu Yu hasn't found any other side effects.
But just this one side effect is enough to give Lu Yu a headache.
Cultivating the Ice and Fire Seventh Heaven to its peak offers a chance to break through the Iron Bone realm, but the power of extinction within his right hand's bones prevents him from tempering the bones, thus making it impossible to fully cultivate the Ice and Fire Seventh Heaven.
However, Lu Yu isn't without a solution; he can first cultivate the Ice and Fire Seventh Heaven to its utmost limit until he can no longer increase his Qi Blood.
Then, with experience points, he can increase his Qi Blood to the threshold of breaking through to the Iron Bone realm.
It's just that Lu Yu currently needs 900,000 experience points for each point of Qi Blood, which is an enormous expense, and he still needs to enhance other martial arts, creating a vast gap in experience points.
