Lin Lei nodded and returned to her space immediately. She quickly went up to the second floor, pushed open the door, and shouted, "system! Where do I put the medicine? "

"Master! The medicine is in the South Cabinet. In the fifth box, there is a blue bottle! "

She took the bottle and looked at it. The surface of the medicine was written in English, and Lin Lei could only roughly understand it. "system, do you want to put all this bottle into the water source? "

"Master! According to your previous description, you only need to put a bottle cap on it.

"There's one thing I want to tell you, master. I feel that the unknown substance in the water should have been produced in the past few days, so I should investigate how the substance was produced? "

Lin Lei raised her eyebrows, "it was produced in the past few days. System, are you sure? "

"Yes! Master. "

"system, was the appearance of this substance caused by me transferring the energy stone inside into space? " Lin Lei voiced out her doubts.

"Master, did you bring all of his things into space when you took the energy stone?

"The energy stone is a multi-faceted thing. It's made of many things. I don't know if it's because of the energy stone.

"I suggest that you go to the place where you found the energy stone and explore it. Maybe you can find the answer you want! "

Lin Lei was deep in thought. Due to the urgent situation that day, if they didn't leave now, both her and Song Yi's lives would be in danger.

She did not notice if there was anything left under the energy stone. What was left behind by them.

If there was really something left behind, would it be the cause of the mutation of the corpse?

Lin Lei's brows were tightly knitted. The more she thought about it, the more anxious she became. "SYSTEM! I'll go out first. You can check this substance again. How many kinds of reasons are there for it to form? "

"Alright! Master, I'll use the instrument to examine it now. This isn't the first time I've seen this substance, but my memory is limited.

I only know his treatment method, but I don't know how it was formed?"

Lin Lei nodded again after hearing that. She brought the medicine out of the space and saw the nervous man waiting outside "Hubby, we should go down and take a look. The system told me just now that this substance might have left something behind when it took away the energy stone?

That's why the water is polluted!"

Song Yi frowned, "En! Later, I'll go in and take a look. Did you put the medicine in the water? "

"En! " Lin Lei immediately opened the bottle cap and poured out a bottle cap, "the system said that this bottle cap is enough. "

"Is this little enough? " Song Yi looked at the bottle cap. There was only a little medicine, but it could evolve the pollution in the water. This was too amazing!

"I don't know either. Let's put it in and test it. " Lin Lei squatted on the ground and directly poured the medicine into the water. The medicine was dark blue, and after it went in, it instantly disappeared "We'll find out after we test the water quality later. "

"En! There's no time to lose. I'll go into the water to take a look first. " After saying that, Song Yi began to take off his clothes. Looking at the water flowing out from the tomb, he estimated that the water inside should be very deep, so he was worried. His wife went into the water.

Lin Lei raised her eyebrows and said, "I'm worried about you going in alone! " Seeing that his actions were swift and neat, leaving only his underpants, she reached out to hold Song Yi's hand. Without stopping him, she went into the water "I want to go down with you. Hubby, DON'T BE RASH! "
