"Then how can there be in this moon stream?" She didn't know much about the species in this world, so she had to ask Ling Yuan for advice.

"This ...... I don't know very well. Ling Yuan's fingers tapped on the table for a while.

"However, I suspect that it is the murderer of Yun Xuan. Why don't we go fishing in the river tomorrow and see if we can catch this jellyfish. ”

"Okay, that's on me." I was originally studying medicine, and Ji Yu said that she was very experienced in capturing these research items.

……

The next day, after meeting the city lord, the two came to the Yuexi River in order to find out the cause of Yun Xu's death.

Ji Yu fished up the plankton net from the river for the tenth time, and the net was made of materials she found in the space, but there was still nothing in it.

She turned her head and smiled bitterly at Ling Yuan, "Still nothing, it seems that we have to lure it over with bait." ”

She took out two vials from her sleeve and shook them at Ling Yuan, "I already knew I needed bait, so I brought it in advance!" You see, I brought a bottle of live Daphnia and a bottle of yeast powder. Yeast powder is the food of daphnia, which in turn is the food of peach blossom jellyfish, and the yeast powder poured here can make daphnia gather and then attract peach blossom jellyfish. We'll just have to catch it again. ”

Ling Yuan nodded, "You're very thoughtful, so let's try it." ”

Ji Yu walked to the water's edge and poured the yeast powder and daphnia into it in turn, but a quarter of an hour passed, and there was still no movement in the water, and there was not a jellyfish that was attracted to it.

She fished the plankton net a few times, but still found nothing.

"If the bait doesn't work, this is the only way to try." Ji Yu took a kettle that she brought with her,

She opened the lid and poured the liquid into the river.

Ling Yuan didn't know what it was, he only saw that the liquid inside was transparent, the same as well water. He couldn't help but ask, "What is this?" ”

Ji Wei smiled slyly: "My bath water, I soaked it in a wooden barrel for two hours last night." ”

"......" Ling Yuan was a little speechless, "Ji Yan, this ...... Do you think peach blossom jellyfish will like to drink your bathwater? ”

"I think the skin flakes of the human body should attract peach blossom jellyfish. You see, we waited so long and didn't see a single peach blossom jellyfish, which means that there are not many peach blossom jellyfish in this river. But why did Yun Qi meet a peach blossom jellyfish so coincidentally when he was in the water? This shows that the peach blossom jellyfish is very sensitive to the smell of the human body, maybe it is attracted by the smell of the human body, so I made two preparations, first using a bait experiment, and then I tried my bath water to see if it can attract the peach blossom jellyfish. I wanted to put my hand in the river and soak in it to attract the peach blossom jellyfish, but this jellyfish is very poisonous, and it would be bad if I accidentally got stung by it......"

Ling Yuan was shocked by Ji Yu's idea of risking her life, and hurriedly said, "Don't go into the water, it's good to use your bath water." Although her own medical skills are very good, but what if, he can't help but worry about her.

Sure enough, not long after, a small pale pink peach blossom really appeared in the water where Ji Yu fell into the bath water, gently swirling under the surface of the water.

"Ah, here it is!" Ji Yu excitedly went to get the plankton net,
