Sheyan could see a large amount of fresh blood flowing on the ground, almost forming an ocean. When he stepped on the blood, it went up to his ankle. At this time, the blood had dried to a thick, semi-coagulated state, so there was a strong resistance when he lifted his foot.
A human certainly could not produce so much blood. To create such a large pool of blood, dozens of humans would have to bleed to death. It was even more impossible for contestants to produce so much blood due to their superior healing and hemostasis abilities, unless they were hung up to bleed.
In such a dangerous wilderness, the large pool of blood was extremely attractive. Sheyan could already see a large number of dangerous insects and small animals crawling over, greedily licking the nutritious liquid that was normally hard to come by.
