Han Sen was afraid that the crab might snatch his part after it finished its own, so he summoned the angel and quickly fed the remaining silver eel to her.
The Archangel was the main force to help him hunt super creatures, so it was essential to Han Sen that she transform again. Sacred-blood meat was not a waste on her.
In addition, this silver eel was as thick as a bucket and more than 30 feet long. Han Sen's part was about 18 feet long. It was too much for him to eat up, while the Archangel ate it with ease. Her mouth moving nonstop, she was not affected by the toxins at all. The silver eel disappeared quickly.
Han Sen then had the time to look at the beast soul of the silver eel. Han Sen felt he was a bit too lucky recently. As long as he hunted a sacred-blood creature, he would gain a beast soul, which even scared Han Sen himself a little bit. He was afraid that he would use up his luck entirely, and then he would have none.
