Green apparently thought of this as well. "Master, do you think you can detoxify the water in the moat?"
"We'll go take a look first. Meg, you will arrange for everyone to throw out everything in the castle. Everyone has drunk the spatial water, so I don't think that they would be poisoned if they touch anything."
Meg agreed, then organized the slaves to clean up.
Accompanied by Green and Meirin, Zhao walked straight towards the moat. The three looked at the moat. It was really like Green said; the moat water indeed released a queer green light. Not only did it scare them, it also made them feel puzzled. Although the water was flowing, the green color didn't dissipate.
Meirin wrinkled her brow as she looked at the moat water. "The water is flowing, but evidently it still contains a lot of toxins. I think that the problem could be from the underground lake."
Zhao nodded. "Grandma Meirin, take out a little water. I want the space to analyze it and test how strong the toxicity of the water is."
Meirin waved her hands, and a bubble of water floated up. Zhao immediately put it in his spatial farm.
The spatial voice sounded in Zhao's head. [Purification of toxic compounds in the contaminated water is possible]
Zhao could now rest assured. "Grandpa Green, Grandma Meirin, let's go to the underground lake. If we want to use the spatial water to remove the water's poison, then we better start at the source."
Meirin and Green were also relieved. To be honest, they were afraid that the spatial water would have trouble removing the poison. Although they believed that flowing water would eventually take out the poison, this would require a very long period of time, which would impact their clan's development.
Just as they were about to head to the mountain, Zhao suddenly stopped, standing motionless while staring at something.
Meirin and Green were both puzzled, so they followed where Zhao's eyes were looking. It was just an area of black soil, nothing unusual in the Black Waste. Green was confused, not knowing why Zhao was staring at it. Meirin also had some difficulty figuring out why he froze, but when she finally understood, her face suddenly went white.
That area of black soil was where Zhao first did his land improvement. Now the color of that piece of land was no different from the rest of the Black Waste.
Meirin's voice quavered. "Master, could it be?"
Zhao nodded, his face pale. If it was really the case in which that land changed back to the original black soil, then his land improvement had failed.
Green didn't understand what was wrong with the two, but looking at their faces, he knew that something bad had happened. He walked behind Zhao as they went towards that piece of land.
