Transformed into a mermaid, the fertility system helped me have a baby

An Fei sighed unwillingly and didn't dare to continue fighting without being careless.

Of course, no one dares to take it lightly, but the cod is like being produced on an assembly line, and the number of them will never decrease no matter how much they are killed.

And Yu Ai suddenly discovered something. They had killed so many cod monsters, but there was not a single monster crystal stone!

"Where is the crystal?" You Ai shouted.

The other three were all stunned, and took the time to look around, but they didn't see any crystal stones.

"Hey! Why is it gone?" Long Man killed another one, and this time they noticed that the crystal disappeared by itself.

! ! ! ! ! !

Guan Landa flicked his tail, fanning the codfish away, and looked at An Fei and asked, "What's going on?"

An Fei shook her head, "I don't know either!"

That doesn't make sense! I've never heard that low temperatures can cause crystals to disappear!

Before Youai could figure out what was going on, three codfish attacked her from three directions at the same time. She had no time to fight back and could only flee. But the direction she turned was not right, and she swam directly to the ground.

She sighed in her heart. The distance was too short. There was no room for her to move. She could only fight in hand-to-hand combat.

She simply turned around, leaned against the ground, drew out her dagger, and was about to fight a bloody battle, but she saw that the cod monsters chasing her turned a corner above her and attacked Long Man.

Long Man: !!!

Guan Landa called out to her, "Yu Ai?"

You Ai was slightly stunned, leaning against the freezing cold ground in a daze, and after a while he responded, "I'm fine!"

She just leaned against the ground, watching the other three people fighting with the cod, but not a single cod came for her, as if she couldn't see them.

"Come down quickly, keep your body low and close to the ground." You Ai shouted to the three people above.

Long Man heard it and glanced over, and saw that You Ai had almost merged with the ground, and there was no cod around him.

Although she was confused, she continued to fight and sank. With the last strike, she lay down on her back. The codfish, which had opened its mouth wide, passed over her with a cry. Guan Landa and An Fei also quickly lay down on the ground.

The cod swimming above seemed not to see them, stopped attacking, and swam forward in a line as if nothing had happened.

Guan Landa raised his head slightly and said, "This is the first time I've seen a monster that can't see the ground."

"It's hard to say!" You Ai looked at the cod in the sky and made some calculations in his mind.

These cod monsters are not invisible, but how do we explain why they don’t attack them while they are clinging to the ground?

Unless these cod don’t see with normal eyes!

The cold air sinks, and if the temperature here is high or low, then the temperature will be lower the further down you go.

Thinking of this, You Ai adjusted his own temperature, lowered it to the lowest level, and rolled on the ground.

Long Man watched her suddenly roll over and asked, "What's that move?"

"I wonder if they can't see the low temperature." You Ai said as he stood up and swam slowly upwards.

Sure enough, the cod swam forward as if it couldn't see anything, ignoring Youai's approach.

In order to verify it, You Ai used her spiritual power to restore her temperature. As soon as she felt warm, Cod discovered her and immediately attacked her.

Fortunately, Youai was prepared and did not fight. She pushed away the cod that was approaching her and then sank back to the ground.

"What is going on?" Guan Landa asked hurriedly when he saw You Ai retreating.

Yu Ai was certain when she saw the cod that were chasing her lose their target and then turn around and rejoin the main group.

"I think the cod can't see us, but they see the heat coming from our bodies," she said.

Long Man said, "What do you mean?"

"Just now I deliberately adjusted the surrounding temperature to the lowest, and the cod seemed not to see me. But when I started to circulate my spiritual power and generated temperature, they discovered me. So I guess what they can see should be the temperature, or heat." You Ai explained slowly.

"So, if we can ensure that our bodies are warm enough for them to not detect, then they will be like they can't see us?" Longman said.

You Ai nodded, "It should be possible."

"Will this work?" An Fei asked worriedly.

Guan Landa hesitated for a moment and said, "Let's try it. We can't do anything if we stay close to the ground." They came here with a heavy responsibility.

Several people began to lower their body temperature to the lowest level. You Ai and Guan Landa slowly straightened up first, followed by Long Man and An Fei.

Sure enough, the cod swam forward on their own as if they didn't see them.

"This is really..." Long Man stopped talking halfway because the cod closest to her turned around and leaned towards her as if it heard her talking, which scared her so much that she immediately shut up.

Is it possible that they can hear even if they can't see? Long Man thought so, but then he heard You Ai speak, "Don't worry, they can't hear it either."

You Ai shouted this sentence, and the cod in front of her turned its head to look at her, but only for a glance before swimming away.

"What's going on?" An Fei said in a low voice, which caused the cod to look at her. She was startled and was about to go back to the ground, but the cod turned around and swam away the next second.

"It's just a little heat emitted by our speech. It dissipates as soon as we open our mouths. They can feel it, but can't catch the source. It's okay." Youai's words were a little longer, attracting the attention of several cods nearby, but they did not attack Youai.

Guan Landa understood, and then he sneered helplessly and amusedly, "What on earth is the reason for this?"

"Anything is possible. Even this place we are in is a magical place." You Ai said, "If An Fei hadn't seen the records before, I would have thought that we were hypnotized and haven't woken up yet. We are just dreaming now."

This remark aroused the same feeling of several other people. Everyone looked at each other and couldn't help laughing.

After laughing, An Fei said, "So what do we do next?"

"Let's go and take a look." You Ai raised her chin and gestured in the direction where the cod were swimming. She wanted to see what was causing these cod to appear in such an endless stream.

The others had no objection, and they then headed in the direction where the cod swam. The result was not surprising, but it was also quite unexpected, they saw a hole.

A dark hole, from which schools of cod swam out continuously.

Long Man said: "What is this?"

Guan Landa said, "Will it be like the original door?"

An Fei shook her head: "These cod can come out from inside, so maybe it's possible to get in."
