Lin Dong had seen this situation happen often back in his old world. But now that he had both Planetary Essense and Qi he wouldn't be able to be stopped on this planet later. The Ji Realm supplied him a constant supply of Qi but it needed to be processed by a Cultivation Technique, and he decided to use the Divine Void Cultivation Technique again. He knew he died last time due to it but he felt it was different this time, but he also wanted to combine the Planetary Essence into his cultivation as it was important. Back in the old world, there were only Weapon Essences and only certain bloodlines or special bodies could access Elemental Essences. But in this world, everyone technically had a special body with the weapon spirits but had no access Qi, so the planet instead produced Planetary Essence for the creatures of the earth to grow stronger.
