"Are you sure?" At this time, even Chen Fan became cautious, the thing whose ability was above the Chiyan Python was definitely not something that Chen Fan could face at this moment, if there really was a fourth-level monster, even if it was just a face, it was possible to pinch Chen Fan to death at any time.

"I'm not particularly sure!" Lin Yuan looked distressed, looked at Chen Fan, and then at Zhao Yu, who was nervous, and loosened his fist very helplessly, "There is indeed a strong energy source below, but I can't sense the breath of life for the time being." ”

"What does that mean?" Chen Fan and Zhao Yu both looked puzzled. Lin Yuan had no choice but to continue to explain, "My perception ability only needs to be able to distinguish between two things, one is the living body, and the other is the energy power that exists in the living body, but I only sense the latter. ”

Chen Fan hesitated, "In other words, the guy who released this breath is very likely to be dead, right?" ”

"Let's just say that, but I'm not particularly sure!" Out of caution, Lin Yuan didn't dare to say too much, thought about it and said, "And it's unlikely that this thing will appear after the apocalypse, because the aura under the hot spring pool is particularly stable, almost connected with the entire mountain range, if you have to find a reasonable explanation to explain this phenomenon, it can only be...... It can only be ......"

Lin Yuan thought for a long time and didn't come up with a suitable descriptive, but Chen Fan explained what he was thinking in one sentence, "Maybe there have been supernatural beings in the Blue Star World for a long time, but it was only later that he died here, and this is the place where his bones sit, so it is possible to generate such abundant energy." Do you want to say this? ”

"Yes!" Lin Yuan exhaled and nodded subconsciously, but then shook his head and said, "But this kind of speculation can't convince myself, human beings must have started to appear after the end of the world, according to your statement, this crack under the ice appeared hundreds of thousands of years ago, which is too ......."

"Everything is possible, in fact, contemporary humans do not know the true history of our ancestors, maybe there really existed in the Blue Star decades and thousands of years ago?" Chen Fan's eyes flickered a few times, as if he thought of something, and his eyes became urgent.

He was able to travel back to the real world ten years after the apocalypse, and other humans may not be able to do this, of course, Chen Fan didn't understand the principle of this kind of travel, but there was an assumption in his heart, could there be someone who completed the time and space jump like himself and was teleported hundreds of thousands of years ago?

This is the only reasonable explanation that Chen Fan can think of, of course, Chen Fan doesn't know what is going on, and he can't draw conclusions about everything in Tianchi so early.

"Have you discussed what to do, those devil bugs may come in at any time!" At this time, the lama Bai Jiang on the side had already found a rope, tied the seriously injured and dying Zha Song to his back, and said to everyone in a hurry.

After his reminder, the three of them remembered that the place they were in was not safe, that ice rock could not block so many devil worms, and the passage to Tianchi was not just that crack, and the longer it dragged on, the more likely they were to fall into a siege.

When Bai Jiang's voice fell, Chen Fan and Lin Yuan had already captured the restless breath surging in the air, and the two of them raised their heads at the same time, and found that the ice above their heads was crawling with insects burning with green fire, these insects were densely crowded like a tide, sticking their bodies to the ice, and with the sound of "click" gnawing, the ice was rapidly melting and becoming thinner and thinner.

The flames emitted by the Zerg monsters also affected the bottom through the barrier of the ice, and the entire cave space fell into a strange green, and it seemed that it would not take long for the monsters to come down.

"There's no time to hesitate, I'll go into the water first, if it's okay, everyone will go into the water like me!" Chen Fan didn't want to fight a war of attrition with these devil bugs, even if he successfully killed all the devil bugs, he wouldn't gain anything, so it was better to use this hot spring to avoid their pursuit.

"It's too dangerous, let's go, you don't look good." Lin Yuan said hesitantly.

"There's no need to argue, I came up with the idea, so naturally I'll be the first to go down!" Chen Fan shook his head and refused, and before Lin Yuan could say anything, he had already jumped off the water.

The temperature in the pool was much higher than outside, when Chen Fan jumped into the water, he immediately rushed to be wrapped in a warm breath, at first he felt very comfortable, but as he continued to dive down, the temperature in the water began to gradually become hot, and the water pressure was constantly changing.

After diving for about fifty meters, when Chen Fan opened his eyes again, there was already a foggy scene in front of him, his eyes had been evolved and transformed, and he could see far away even under the water, but there seemed to be some kind of shielding obstacle in the water of this hot spring pool, cutting off Chen Fan's sense of the environment.

Not only that, but even his powerful sensory organs were shielded, and he could only sense a distance of four or five meters, and the further he dived, the more powerful the sense of oppression generated in the water became.

The water in the hot spring pool is not calm, and the surrounding pool water is still bubbling and bubbling, and I don't know how deep it is. Faced with this environment, Chen Fan also fell into hesitation, unable to determine whether to continue diving, but just when he hesitated, an undercurrent appeared in the water, washing over him without warning.

Chen Fan instinctively tensed his muscles, until he was sure that this undercurrent was not a threat to him, then he relaxed a little, as the undercurrent paddled in the depths of the pool, about two minutes later, Chen Fan found a two-meter diameter hole, the hole was filled with pale red light, at first it felt very shallow, until he approached the hole to see, only to find that the cave was full of reefs, zigzag surge I don't know how deep it was to the bottom of the water.

Moreover, there was an extraordinarily pure energy gushing out of the cave, and its scale was unimaginably huge, even with Chen Fan's heart, he couldn't help but tighten his pupils suddenly, and he groaned secretly in his heart, "It seems that the energy that Lin Yuan discovered is hidden in this channel......"

At this time, Chen Fan already felt a little stuffy in his chest, and he had been swimming in his heart for a long time, unable to breathe in fresh air, which made him feel very difficult, and he hesitated in his heart, and finally chose to stay away and return, paddling backwards along the undercurrent, and soon stretched his neck out of the water again.

The moment he came out of the water, Chen Fan took a few breaths of air fiercely, and the shouts of Zhao Yu and others were also heard in his ears, "How are you, have you found anything underwater?" ”

Chen Fan shook off the wet droplets on his face and pointed to the hot spring passage below, "Lin Yuan is right, the Yuan power here does come from below, I found a secret passage nearly fifty meters underwater, I don't know how deep it is, but all the breath is washed out along that dark passage." ”

"Is there such a thing?" Lama Bai Jiang's eyes lit up, and he hurriedly said, "I have been here countless times, but I have never tried to go into the water, so the reason why we were able to evolve in advance is also because of the mysterious aura in that secret passage?" ”
