The Reincarnated Beast was often evolved from the ordinary monster. If the unhatched parasite egg was put into the other rare monsters, the egg would be swallowed by the rare monster's Parasitic Soul Worm, turned into the most basic nutrients and would not retain any ability.
Dean looked at the parasite egg and his eyes flashed slightly. Although it was unhatched, it was the parasite egg of a legendary monster. Its value was still amazing. If it was exchanged on the market, it could be exchanged for more than ten rare Parasitic Soul Worms.
However, this thing made Dean a bit tangled. If he wanted to hatch it, he had to pick a suitable new host, and it would take at least a few months for the parasite egg to hatch in the new host body, so he had to carefully raise and take care of the parasite egg during that period.
