The soil in the field was very wet, obviously just watered. At this time, the Xu Dianbu nodded and confirmed Zhang Zong's guess: "Yes, the weather has been dry recently and it has not rained yet, so Yang Shaoqing discussed with us and decided to water the crops. It was last night, but in just one night, all the crops died, and even if they drowned, they would not be so fast?"

Xu Dianbu's words also made Di Renjie nod in agreement. Even if there was too much watering and waterlogging occurred, it would take several days for the crops to happen, rather than just one night like now.

"How did you water it? Take me to see!" Zhang Zong said again. He only watered last night, but all the crops died today. No matter how you look at it, it makes people feel that there is something wrong with the watering this time.

"Bachelor, please follow me!" Xu Dianbu nodded immediately. He also hoped that Zhang Zong and Di Renjie could find out the cause of death of these crops as soon as possible. Now that this matter has been reported, it is likely that His Majesty will alarm His Majesty. If Zhang Zong could find out before His Majesty and others arrive, they might have a glimmer of hope.

Xu Dianbu took Zhang Zong and Di Renjie for a while and finally arrived at the southeast corner of the field. A ditch was dug out here. There was a river upstream, and a water truck stood by the river, which could lead the water in the river and then pour it into the ditch and flow into the field.

There was still some water that had not flowed out in the ditch. Zhang Zong squatted down and observed it carefully. Di Renjie also saw some clues at this time and asked in a low voice: "Brother Zhang, do you suspect there is something wrong with this water?"

"I let the crop die overnight, and I happened to have watered it last night. It really makes people wonder if there is something wrong with the watering this time?" Zhang Zong nodded slightly.

"If there is any problem with watering this time, is it that someone poisoned the water?" Di Renjie also touched his chin and said to himself, but then he said with some confusion, "But I have only heard of poisoning people and poisoning crops. Is it the first time I have heard that there is any poison that works on these crops?"

"The poison that works on plants is not less than that on humans. For example, I know a poison that plants will die when touched. And the most terrifying thing is that this poison is colorless and tasteless!" Zhang Zong seemed to have seen something, and said to Di Renjie with a smile.

"This is impossible. As far as I know, although there are many poisons in this world, it is almost impossible for poison that can really poison people to death to have colorlessness and tastelessness!" Di Renjie shook his head in disagreement when he heard this.

"Brother Di, you are wrong. This poison is really colorless and tasteless. Even if you drink it, you will definitely die!" Zhang Zong smiled again.

"Is there really such a poison?" Di Renjie couldn't help but ask with a shaken question when he saw Zhang Zong's confident look.

"Of course, the name of this poison is..." Zhang Zong deliberately paused when he said this, and then he said the name of "poison", "Keep water!"

"Burn...boiled water?" Di Renjie also looked stunned when he heard this, but soon he realized that boiling water is really a "poison". Using it to water plants will definitely burn the plants to death. If someone drinks boiling water directly, it can also burn people to death.

"This... this is really a poison!" Di Renjie finally showed a laughing and crying expression, but then he was stunned again and said excitedly, "Brother Zhang, do you mean that someone boiled the water and poured it into the ground, and then burned the crops to death?"

"Although boiling water is a good way, it is impossible to achieve. After all, although this field is not big, it is not small. It is impossible to achieve boiling water on a few acres of land." Zhang Zong shook his head and denied.

"Brother Zhang, why do you say boiling water?" Di Renjie was confused when he heard this. In fact, he felt that using boiling water to water the ground was not realistic, but apart from this method, he could not think of any other method.

"I actually want to tell Brother Di that some things that seem harmless usually can be used to do evil!" Zhang Zong then explained with a smile. After saying that, he stretched out his finger and dipped them in the water in the ditch, then put them beside his mouth to taste the taste, and then sneered, "It's true!"

Seeing Zhang Zong's actions, Di Renjie was curious and followed suit. He immediately reached out to dip some water and tasted it. Then he widened his eyes and said, "It's salty? Why is this water so salty?"

"Brother Di, do you know that there are two places in the world where people are most often thirsty, one is the desert and the other is the sea!" Zhang Zong sneered and said again.

"How can the sea die of thirst? Isn't the sea full of water?" Di Renjie asked with confusion after hearing this. Although he was good at judging cases, he was from Taiyuan. Later, he was in Guanzhong, Henan. He had never seen the sea at all. He had no idea about the sea. He didn't know that not only could sea water not quench thirst, but people who would drink sea water died faster.

"The sea water is salty. If a person drinks sea water, he will become more and more thirsty as he drinks, and eventually dies faster." Zhang Zong explained.

Di Renjie was extremely smart, and immediately understood after hearing this, and immediately slapped his head: "I understand that sea water can make people who drink die faster, and the same is true for crops. If sea water is used to irrigate the fields, these crops may die of thirst!"

"Yes, this is just like the fact that plants cannot grow in saline-alkali land. If someone adds a lot of salt to the water and then uses this water to irrigate the crops, of course, it will water the crops to death!" Zhang Zong finally said his conclusion.

Just now, Zhang Zong carefully observed both sides of the ditches and found a white trace at the junction of the water and the ditches wall. Although it was not very obvious, you could still see it after careful observation. These white traces are the salt crystals left by the evaporation of water.

"What a vicious way, use salt water to fill the ground. Not only are these crops destroyed, I'm afraid this land will not be able to grow things within a few years!" Di Renjie said hatred when he heard this.

"Brother Di, if you want to poison such a large crop, you must have a lot of salt. Salt and iron have always been a product strictly controlled by the court. You'd better check it carefully and see who has accumulated salt in large quantities recently. You should be able to find some clues!" Zhang Zong said again and suggested.
