From this point alone, Bei Feng was undoubtedly much luckier than the other cultivators on Earth in that he had an alternate path to choose.
But if he went to another world through the Myriad Heavens portal, he could only stay in that world for a year. That was not what he wanted.
As of now, he no longer had any attachments on Earth, and could leave at any time. As for the Heavenly Demonic Corpse, there was still a long time until it would be born. If he had a path out to another world, he could always use it to come back in the future to collect the corpse.
A thousand years was simply too long. There was no way he could stay here, waiting for it to come out.
As for the other Demonic Corpse in the underground crypt under Mt Qing Ling, the government had sent many people in to explore the crypt. However, the casualty rate was still somewhat high.
