Without hesitation, Han Sen summoned his horn bow and mutant black needle arrow and shot it at the sacred-blood copper demon that was swooping down.
When Jin Rijie was about to fight the sacred-blood copper demon, he suddenly saw a black arrow flying toward the sacred-blood copper demon's eyes.
However, the sacred-blood copper beast reacted very quickly. Its six blade-like claws locked the black arrow in a criss-cross.
But the moment the six blade-like claws locked onto the arrow, the arrow spun violently like a drill bit. It bounced off the blade-like claws of the copper demon and violently drilled into the copper demon's eyes. Immediately, the arrow pierced through the copper demon's head.
Thump!
The seemingly powerful sacred-blood copper demon fell from the sky and died.
"Sacred-blood copper demon killed. No beast soul gained. Eat its essence to gain zero to ten sacred geno points randomly."
Hearing the voice in his head, Han Sen licked his lips and felt sorry that he did not gain a beast soul from such a good sacred-blood copper demon.
Jin Rijie and Jin Mingli were dazed. It was terrifying to kill a sacred-blood copper demon with one arrow.
After the sacred-blood copper demon was killed, the rest of the mutant copper demons turned around and ran into the cave. Han Sen and the rest of the team chased after them.
However, they only killed a few mutant copper demons that were too slow and the rest were long gone. The cave was quite deep and crisscrossed. Han Sen and the rest of the team did not chase further, but went back to deal with the body first.
The Copper Demon's body was as hard as metal. There was no edible flesh inside, only a small amount of blood essence that flowed in its body.
Han Sen carefully released the purple essence blood from the body of the sacred-blood copper demon and stored it in a bottle. A large sacred-blood copper demon only had as much essence blood as a bottle of water.
Because Han Sen killed the sacred-blood copper demon himself, he did not need to share it with others. Han Sen swallowed all the essence blood and listened to the voice telling him that he had gained three sacred geno points.
This was not a small amount. After all, most of the sacred-blood copper demon's body was inedible. However, the essence blood alone could give him three sacred geno points, which made Han Sen quite satisfied.
Han Sen's sacred geno points had reached 83, and it was only a matter of time before he maxed out on his sacred geno points.
"Copper demons are hard to come by. Should we go to the cave and kill the rest of the mutant copper demons? Maybe we can gain a beast soul," suggested Jin Mingli excitedly after dealing with the body of the copper demon.
Han Sen naturally would not object to this suggestion. Even a mutant shapeshifting beast soul was quite popular. No one would say no to money.
Jin Rijie asked for Professor Sun's opinion, but Professor Sun did not respond. In addition, there might be different plants or fungi inside the cave, which Professor Sun was also interested in.
The four of them entered the cave. Although there were many caves in the cave, they were all quite spacious. They didn't encounter any danger along the way. They didn't even know where the Copper Demons had run off to. They had been paying attention to their surroundings along the way, but they couldn't find any trace of them.
The cave was quite large. The deeper the four of them went, the wider it became. After walking for more than two hours, the cave suddenly opened up. The huge cave seemed to be an underground space. There was an underground river about 30 to 40 meters wide flowing through the cave, all the way to the opening on the left side of the cave.
The water flowed very fast. However, for some reason, the sound of the water was not loud, and the surface of the water looked calm.
Through the light of the torch, Han Sen saw the group of copper demons on the other side of the river, twisting their waists and continuing to escape.
"Should we continue to chase them?" Jin Rijie looked at Han Sen and asked.
Han Sen looked at the dark underground river and could not help but frown. He was still a little scared of the underground river. The two huge ink-jade dragons were in the underground river.
Ink-Jade dragons were ferocious sacred-blood creatures. Even if he encountered them now, he would not dare to be careless.
The cave was so dark that the light of the torch could not shine into the water. Instead, the reflection of the fire made it even harder to see clearly.
Han Sen was a little scared that a sacred-blood creature like an ink-jade dragon would suddenly appear in the river. No matter how strong he was, he was no match for an ink-jade dragon underwater.
"Do you have wings?
If you want to chase them, let's fly over them, "Han Sen hesitated and said. He was a little scared to go into the river like this.
Jin Rijie smiled awkwardly and said, "We do have wings, but we only have one mutant wing beast soul and one primitive wing beast soul."
"That's a bit troublesome. I only have one primitive wing as well."
Han Sen did not mention his sacred-blood wings. It was better not to let others see them.
"How about this? I will use my mutant wings to carry Professor Sun. You and Ming Li can fly over by yourselves," Jin Rijie thought about it and said.
Han Sen shook his head slightly and said, "I will fly over first. If there is no danger, you can cross the river."
Han Sen felt as if there was something wrong with the river, and it gave him goosebumps. But it was just a feeling, and he didn't know what it was. Since they had come this far, he couldn't just turn back.
In addition, on the way here, Professor Sun had found some interesting plants. It seemed that he was very interested in moving forward.
Han Sen summoned his black-feathered beast and flapped its wings to a height of three to four meters. Then he slowly flew over the river.
Primitive wings could not fly high or fast. This was the limit. Han Sen stared at the dark underground river as he flew. If anything happened, he would be able to react in time.
Jin Rijie and the others watched Han Sen slowly fly over the river and were a little nervous. The environment here was really dark, and humans were naturally afraid of water and the unknown, which made them break out in a cold sweat.
When Han Sen flew to the center of the river, he suddenly felt that something was wrong. A chill ran down his spine.
Boom!
The calm surface of the river suddenly exploded. A giant wave was created, and a giant creature emerged from the water. It opened its mouth and looked as if it was going to swallow Han Sen whole.
"D * mn! I knew something was wrong. Now, something is wrong." Han Sen's heart jumped. He stared at the bloody mouth that had just emerged from the water.
