After a while, he'd traveled several tens of kilometers, and he was already moving slower than he normally would as a safety precaution.
Otherwise, if he were charging through the mist as quickly as he could, he would've covered several hundred kilometers already.
He had once skirted around most of the outskirts of this sea of Black Infernal Mist, and even when flying as quickly as he could back them, it had taken him around a month or two to go the entire way around one side.
He didn't know where he was currently situated within the sea of mist, but it would most likely take him quite a few days to emerge from this area on foot.
As such, Han Li wasn't in a hurry to forge ahead. Instead, he merely progressed at an even pace while considering his trip into the earth abyss and the infernal river.
During this adventure, he'd had quite a few perilous experiences and had almost been reduced to a puppet by the demon monarchs, but he'd also secured bountiful rewards.
He had learned the true method to use his Divine Devilbane Lightning from Mu Qing and also secured a vial of Five-Colored Peacock True Blood from her. From Di Xue, he'd obtained the refinement methods for spirit servant puppets, thereby allowing him to master the refinement methods for the Nine Palaces Heavenly Talisman and the Armor Origin Talisman. On top of that, the elderly man with the Jiang surname had passed the new Azure Essence Sword Art onto him, along with the method to refine the Azure Bamboo Cloudswarm Swords again. If he focused enough attention on those two things in the future, he'd presumably be able to make his sword formation a lot more powerful.
However, none of those things were as valuable as the Divine Infernal River Elixir that had been promised to him.
From what he knew of already, this elixir could alter one's constitution, thereby allowing one to absorb more of the world's origin Qi than they'd normally be able to. This was an incredible item, and he naturally didn't want to give up on it.
With this divine elixir, he'd be saving himself countless years of cultivation. For a cultivator with ordinary aptitude like Han Li, that was definitely something of the utmost importance.
The items on the list given to him by the elderly man were all extremely difficult to find, but there was still hope for him if he had a time period of 1,000 years to find two-thirds of the items on the list.
With that much time allotted to him, Han Li was relatively confident that he'd be able to achieve such a feat.
However, what he had to do now was to return to his cave abode on the island as quickly as possible, then go into seclusion so he could consolidate the rewards that he'd reaped from this trip. Once he reached the pinnacle of the late-Deity Transformation Stage, he'd be abl
