Lighting was a relatively simplistic Essence. Many Dao Realm experts would gain enlightenment of it as their first Essence. One of the reasons for this was that it was relatively easy to understand. Because of that, Essence of lightning was not uncommon in the starry sky of the Vast Expanse. Even in the Mountain and Sea Realm, or other worlds, Dao Realm experts with the Essence of lightning were nothing rare.
However, people who transformed the Essence of lightning the way Jin Yunshan had done for his ninth Essence... were as rare as phoenix feathers or qilin horns.
From this, it could be seen how grand Jin Yunshan's aspirations were!
As he said, his ninth Essence was not merely the ordinary Essence of lightning. No, his was Tribulation Lightning of the Vast Expanse. If he did manage to Transcend into the Daosource Realm, and become a Dao, then if his suppositions were correct, he could represent the Vast Expanse as the lord of Tribulation Lightning!
