The two walked along the deep cave for about half an hour, and nothing strange happened along the way, it felt like an ordinary natural cave.

"Looks like there's nothing strange about this cave, it's just a bit of trouble to find an exit." Qin Tian groaned after groping around the surrounding rock walls.

Seven also nodded in agreement, this place is indeed very ordinary, it should just be a naturally formed cave under the mountain, and he doesn't even bother to use the special ability of the stone pendant.

Suddenly, a breeze blew in front of them, bringing with it a strange smell that seemed to be somewhat salty.

"This taste...... How does it smell like seawater? Qin Tian sniffed and said in surprise, it stands to reason that Taihang is still far away from the sea, and it is impossible to smell the salty smell of seawater, unless they have been teleported to an extremely far place.

"Let's go, let's take a look." Qin Tian felt strange and insisted on going to see what was going on, after all, the place where the wind was blowing was likely to be the exit.

No. 7 couldn't resist Qin Tian, but he also had some doubts in his heart, the red glow of the stone pendant quietly shrouded his eyes, and then, he had to rely on its eye ability.

The two were a little closer at this time, after all, the salty smell brought by the breeze was a little unusual, maybe it was a well-arranged killing game, in case one accidentally touched something, the two of them were together to help each other.

Suddenly, a bloody arrow with a thick fishy aura shot towards No. Seven from the depths of the cave, even No. Seven hadn't reacted yet, but fortunately, Qin Tianyi beside him pulled No. Seven and held him in his arms to avoid a catastrophe.

"If it's okay, let me go." No. 7's cold voice spread in Qin Tian's arms, and at the same time, he also forcefully got rid of Qin Tian's chest, and his face was extremely ugly.

Qin Tian felt that No. 7's reaction was a little strange, but he didn't understand what was wrong with him, could it be that he complained because he was in danger after following him?

However, he still naturally let go of the hand holding Seven, after all, Seven seemed to have a bad attitude towards him now, and he didn't dare to provoke him too much.

"What was that? It feels like an arrow with blood on it. Qin Tian looked at the blood arrows that disappeared in front of him and behind him, and said in disbelief.

"Yes, indeed, but the arrow was made entirely of blood, and it came from a short distance ahead." Seven looked solemnly at the depths of the cave, although it was pitch black, he could barely make some clues with his pupil power, and the scene ahead was completely different from here.

"Be careful, I'll go ahead of you." Qin Tianyi stopped No. 7 and took the lead in walking forward, half of his body was protected in front of No. 7, holding the jade talisman and the jade plate in both hands, if he encountered danger, he could also react.

No. 7 hummed softly, Qin Tian would still care about him, and under the premise that he had such a bad attitude towards him, thinking of this, he couldn't help but raise his head and glance at Qin Tian.

The two of them walked slowly for about ten minutes, and the rock walls around them became more and more open, obviously going to the deepest part of the cave, and this was the source of the blood arrow.

"This, this is ......?"

Qin Tian and No. 7 were shocked when they saw the scene in front of them, the sight in front of them was not a gloomy sea of blood as they imagined, but a clear waterfall, surrounded by lush vegetation, and there was no trace of murderous aura at all.

"Could this really be where blood arrows are generated? It doesn't look like it. Qin Tian muttered to himself, but the dim light still seemed to see through the essence of it, maybe there was a trap somewhere.

No. 7 stared at the clear spring under the waterfall, there seemed to be a secret passage under the clear spring, which was really a bit strange, but there was no trace of blood anywhere, where did those blood arrows come from? Could it be that it was really made up out of thin air?

Just as Qin Tian was about to get closer to that Wang Qingquan, two more blood arrows suddenly rushed out from under the clear spring, heading towards Qin Tian's head and torso respectively, if he were an ordinary person, he would definitely be shot into a sieve.

But Qin Tian has years of practicing karate skills, a catwalk sideways to dodge a blood arrow shot at the head, but the shot to the torso is really difficult to dodge, his left hand jade plate against his chest, forcefully offset the blood arrow.

The blood arrow dispersed, but the thick bloody aura on it rushed towards Qin Tian, Qin Tian suddenly felt so disgusted that he almost vomited out, this bloody breath did not look like it was from an animal, could it be human blood?

However, it can also be determined that there must be secrets under the clear spring, and the bloody qi on these blood arrows also comes from there, and the secrets hidden in these blood will definitely be able to find clues at that time.

"Why don't we go down and have a look?" Qin Tianyi decided to go down to explore, after all, now that the road has come to an end, they haven't found the exit yet, it seems that they can only go down and see if there may be a way to get out.

No. 7 was silent, he didn't think that Qin Tian's decision was correct, in case of danger, they didn't even have a chance to escape, thinking of this, No. 7 decided to observe it himself.

His eyes flashed purple as he stared at the secret passage below the clear spring, where a boulder blocked the spring from entering, and on the other side of the boulder was a snake-shaped passage with a blood-red rock wall clinging to it, looking particularly permeable.

But as far as Seven could see, there seemed to be a bright light at the end of the passage, which seemed out of place with the entire dark red environment, and if he guessed correctly, there should be an exit to get out, but it could also be a more complicated environment.

Besides, it's useless to stay here, I don't know who built this waterfall and the clear spring, it is like a cycle of reincarnation, and the end of the waterfall is just a stream of water fed back by the clear spring.

"Okay, let's go down, but there's a boulder down here, what should we do?"

Qin Tian looked at the bottom of the clear spring and thought for a while, they didn't have ready-made diving equipment here, this was a troublesome thing, and the boulder was also a trouble, if it was forcibly broken and the spring water poured into it, it would be really dangerous.

No. 7 looked at Qin Tian's bewildered face, knowing that he didn't have any ideas, maybe he was still a landlubber, and this kind of diving work still had to rely on himself, Qin Tian would definitely not be able to count on it.

"Forget it, I can't think of a way to do it, so I'll go down and explore the truth first."

No. 7 said that, no matter what Qin Tian was going to say, he jumped into the clear spring.

Looking at Qingquan, who disappeared in an instant, Qin Tian was a little worried, and when he got closer, No. 7's figure was moving rapidly in it like a fish in water, and Qin Tian was amazed to see it, this guy is not bad in the water.

Next, wait for Seven to find out the situation there before we can do it.
