The sacred-blood black-feathered beast king turned around and tried to escape, but Han Sen caught up with it again. The beast king roared angrily, but did not struggle anymore.
While Han Sen was wondering, he suddenly found that the lights on the walls and vines seemed to be frightened by the roar of the sacred-blood black-feathered beast king. They suddenly flew up and gathered toward Han Sen and the sacred-blood black-feathered beast king.
"What are those?"
Han Sen was shocked. When he took a closer look, he noticed that the lights were actually blue butterflies. They were each the size of a hand, and their blue wings glowed with a blue light. They were incredibly beautiful.
Soon, a group of blue butterflies flew to Han Sen and the sacred-blood black-feathered beast king. At this time, Han Sen realized that the sacred-blood black-feathered beast king did not come here for no reason. Obviously, it wanted to use these blue butterflies to deal with Han Sen.
Han Sen was alert. Seeing a blue butterfly was about to land on him, Han Sen waved his dagger and cut it in half.
"Primitive ghost butterfly killed. No beast soul gained. Meat not available."
While Han Sen was wondering what had happened, the Ghost Butterfly he had cut in half suddenly turned into a blue flame and exploded everywhere.
Han Sen turned around and hid on the other side of the sacred-blood black-feathered beast. When the flame fell on the sacred-blood black-feathered beast, it was so hot that even its fur was burning.
Groups of ghost butterflies rushed over and hit Han Sen and the sacred-blood black-feathered beast, turning into a ball of blue flame as soon as they hit.
There were so many ghost butterflies that neither man nor beast could dodge. The sacred-blood black-feathered beast was burned and screamed.
Han Sen was not having a good time either. His sacred-blood armor was not afraid of the ghost butterflies, but there were blue flames everywhere. The armor could not withstand the high temperature of the flames.
In just a moment, Han Sen felt that he was about to be roasted. He cursed the sacred-blood black-feathered beast in his mind. However, he had no time to care about the beast at this moment and jumped into the underground river. If he did not escape, he would be roasted into suckling pig.
Almost at the same time that Han Sen let go of the sacred-blood black-feathered beast and jumped into the river, the sacred-blood black-feathered beast also jumped in, but it was very fast.
Such a huge body, after folding its wings, actually looked like a big fish, quickly swimming downstream along the underground river.
Han Sen gritted his teeth and followed it. There were so many ghost butterflies here, many of which were mutant. The flames they produced were so hot that it was not a good place to stay.
However, the sacred-blood black-feathered beast king was too fast. It was getting farther and farther away from Han Sen and was about to lose Han Sen.
Han Sen would not let it go. He pulled open the horn bow and shot an arrow at the sacred-blood black-feathered beast king. The arrow could not travel too far underwater, but Han Sen was not far away from the sacred-blood black-feathered beast king. The mutant black stinger arrow flew through its feathers, and the string on the arrow also entangled the beast king's feathers.
The sacred-blood black-feathered beast king dragged Han Sen along.
The creature swam faster than a fish. In the turbulent river, it was even faster than the current. It kept pulling Han Sen into the depths of the water and swimming forward.
"Is this guy an amphibious creature?"
After following the guy underwater for a while, Han Sen could not hold his breath. After all, he could not breathe underwater. His body had not evolved to that level yet, while the sacred-blood black-feathered beast king seemed to be able to breathe underwater. Otherwise, it would have died long ago.
However, it was still full of vigor and didn't seem to be out of breath at all.
Han Sen gritted his teeth and called back the mutant black stinger arrow stuck in the sacred-blood black-feathered beast king's feathers. Letting the sacred-blood black-feathered beast king swim on its own, Han Sen rushed out of the water, gasping for air.
He looked around and found that he was still in a cave. He did not know how big this underground cave was, and there were still some Ghost Flame Butterflies on the walls. However, there were very few of them, and they were just like stars in the sky. They were just lying on the walls and vines.
Since he had lost the sacred-blood black-feathered beast king, it was not too dangerous here, so Han Sen was not in a hurry.
Glancing at the ghost butterflies on the walls, Han Sen shot at one of them with his horn bow. With a snap, the ghost butterfly turned into a ball of blue flame.
"Ghost butterfly killed. Primitive ghost butterfly beast soul gained. Meat inedible."
Han Sen was overjoyed. He was in luck today and gained another beast soul. Although it was only primitive, it was usually a one-time use beast soul.
For example, the six-winged poisonous bee beast soul that Son of Heaven once used could only be used once. However, this beast soul was generally more powerful than other beast souls of the same level.
The other Ghost Butterflies were alerted, and they all flew towards Han Sen. Han Sen fired his arrows, and after a while, all of the butterflies were killed. Blue flames exploded in the air around Han Sen.
After killing all the ghost butterflies, Han Sen climbed out of the water and sat on the rock to check his trophies.
In addition to the primitive ghost butterfly beast soul, Han Sen also gained a primitive black-feathered beast soul and a mutant black-feathered beast soul.
Primitive ghost butterfly beast soul: one-time use concealed weapon type.
Primitive black-feathered beast soul: flying beast soul.
Mutant black-feathered beast soul: flying beast soul.
Han Sen was overjoyed when he saw the types of the beast souls. There were too few creatures around Steel Armor Shelter that could produce flying beast souls. Few people in the entire shelter had wings.
It was great that these black-feathered beasts could produce flying beast souls. Han Sen himself lacked a pair of wings. After all, the wings of the purple-feathered dragon could only be used in Dollar mode. Otherwise, he would be exposed.
The only regret Han Sen had was that he did not kill the sacred-blood black-feathered beast king. Otherwise, he might have gotten a pair of sacred-blood wings.
"I will go back and kill a few more black-feathered beasts. Even if they are primitive flying beast souls, I should be able to make a lot of money by selling them to young men and women who like to look cool."
Han Sen summoned the ghost butterfly beast soul. Suddenly a blue butterfly flew out and landed in his hand, turning into a dark blue, butterfly-shaped concealed weapon as thin as a cicada's wing.
The two wings of the concealed weapon were thin and sharp, which made Han Sen feel a little creepy.
Han Sen cast the butterfly away. However, because of its shape, the butterfly did not fly straight away. Instead, it made a weird curve in the air and flew back to Han Sen after a few circles.
