The head of the Sword Hut should have known God Lu's secrets. Thus, she knew that as long as the old King of Gods wanted to, he would be able to reach that realm.
But there was a price to pay. He had to absorb the dark map, which stood alongside the celestial map. It was like yin and yang. He also had to overcome desire in order to achieve the seventh level of nebula.
God Lu had always had the ability to reach paramita. Lu Shu believed that he definitely had enough distress points to do so, but decided not to.
Lu Shu felt that if God Lu had killed Lural in order to advance his realm without any emotions, then all this would not have happened. He would not have given up his strength to reincarnate. The head of the Sword Hut would not put everything down for a person like this either.
God Lu would not have any emotional burden. He was a demon inside out.
